For all the repeat questions on ROM threads - Verizon Galaxy Note 4 General

I frequent the JasmineROM and CyanogenMod threads in this forum and have noticed (and answered) many repeat questions: questions that have already been answered maybe a page or two back. I've noticed frustration in the answers to these questions (I've felt it myself), so I decided to start a new thread that will address the questions and provide the answers. It won't stop the questions from happening, but at least we can all just paste a link instead of writing the same paragraph over and over to people who don't seem to do any research.
---------------------------------------------------------------
Here's the format I'll be using for the questions and answers. I'd really appreciate it if suggestions could follow it, but it isn't necessary at all.

(This may be in the wrong section, but I figured General would fit it best. Please move it if it's better somewhere else.)

I know I'm going to forget to include quite a few things. If you've seen a repeat question, I believe (I don't know for sure ) that replying to this post with at least the repeat question and then allowing me to edit it into this post will be a good way to go about this (I'll give credit with a name and link to the post).
---------------------------------------------------------------
Without further ado, here's the "FAQ":
Q: How do I root my Note?
A: http://forum.xda-developers.com/note-4-verizon/general/guide-noobs-guide-to-perm-root-twrp-t3360883
Q: How do I upgrade to the MM bootloader and modem?
A: http://forum.xda-developers.com/not...t/howto-bootloader-unlock-upgrade-to-t3398144
Q: I have no WiFi after using the latest version of CyanogenMod, JasmineROM, PaulPizz or any other Marshmallow-based ROM.
A: Make sure you have upgraded the bootloader and modem to Marshmallow. Guide here.
Q: On CyanogenMod, I'm losing LTE and only getting 3G.
A: Reboot into Recovery and then back to System. It won't fix it permanently, but it will restore LTE for a while.
A2: Delete the StraightTalk APN from your APN settings. (Obviously, you shouldn't do this if you have StraightTalk.) (Not everyone has a problem with the ST APN, but I figure I'll put this here.)
Q: Screen rotation isn't working on JasmineROM 6 or 7.
A: Many people have reported that this is a result of debloating. Not everyone has the issue, but those who have say one they remove Facebook and DT Ignite (among others), screen rotation breaks.
Q: Bluetooth audio is stuttering in CyanogenMod 13.
A: The workaround for this is to enable Daydream. That will prevent the phone from going to sleep, but will display a dark background with a clock, allowing you to still get a fast charge. The problem with BT audio lies in a CyanogenMod change that caused some problems with Bluetooth discovery upon device wake. hsbadr is working on a new build with the fix incorporated.

Q: I'm already on Marshmallow with a locked bootloader. Is there hope for me?
A: Yes. You need to downgrade to Lollipop first. Flash the full firmware (thanks, @hsbadr!) on ODIN. Make sure that auto reboot is unchecked. When you get a "pass" in ODIN, boot into recovery and do a factory reset, otherwise you could get a bootloop. It takes a while for the first boot... upwards to 15 minutes... so be patient. Then you can start to unlock the bootloader. The bootloader must be unlocked before you can root.
Q: What ROMs can I flash?
A: That's a tough one. If you have a Lollipop unlocked bootloader you can only flash a ROM based on a Lollipop bootloader. Often the developer of the ROM will put the base of his ROM in the title of the thread as the bootloader firmware name (ie N910VVRU2BPA1) is a Lollipop firmware. Otherwise, you'll find the information at the lower left corner of the opening post. If you don't know, ask in that thread.
Subsequently, you must have an unlocked Marshmallow bootloader in order to flash a Marshmallow bootloader based ROM.
Confusing the issue more is the fact that it's possible to have a Marshmallow ROM use a Lollipop bootloader.
You can find all of the ROMs that are specifically for the N910V Note 4 variant (Verizon) here.
Q: I hear there are ROMs for other Note 4 variants. What's up with that?
A: True deal. Some of the other variants, the international models specifically, have been unlocked for awhile and there's a thriving development community. You can find those ROMs here. You've gotta know some stuff before you can flash one of their ROMs.
1) Stick with ROMs developed for the N910F and N910G variants. The radios are closest to ours. Flash a ROM for another variant and you're now a test pilot.
2) The same rules apply to their ROMs: Lollipop bootloader on your phone? Lollipop based ROM. Same for Marshmallow.
3) You'll need to flash a data fix to make their ROMs work on the Verizon network. Further, you may need to flash a kernel to make wifi work. I had luck with the Oscar kernel when I tried the Noble ROM last week.
(Note by Zacharee1: I've only had luck with the data fix on TouchWiz ROMs. AOSP ROMs, like CyanogenMod and Resurrection Remix, have problems with the data fix, resulting in reduced performance and still no cellular.)
Q: I've gotta, gotta, gotta have wifi calling.
A: At this time, you're pretty much stuck with a stock based ROM like Jasmine or PaulPizz. @hsbadr is working on getting it to work on CM13 but I'm waiting for other issues with that ROM to clear up and I am not current on its features. You will not find it on any of the international based ROMs.
(Note by Zacharee1: WiFi calling still does not work on CM. I have hopes for it in the future, but I may be moving to T-Mobile, where I'll probably have it anyway, so I won't be current on this either.)
Q: What are some tips about choosing and flashing custom ROMs on my Note?
A: Read these tips:
1) Find a ROM that interests you and has the features you can't live without. Most ROM developers are pretty thorough in the opening post or so regarding what you can expect.
2) Read the thread cover to cover. But Douger, some of those threads have hundreds upon hundreds of pages. Why? Because you'll know what issues others have had with the ROM and you'll find possible workarounds. You'll find out whether or not there are any showstoppers that'll keep you from using it as a daily driver.
3) Before you flash anything, do a full nandroid backup. In TWRP, check off all of the blocks. If crap blows up in your face, you can be using the phone again in about ten minutes of recovery time. Otherwise, you can spend hours setting the phone up again after flashing a ROM again.
4) Speaking of spending hours, plan on it. If you don't have the time, wait till you do because you;
5) Need to do a full wipe. That means data, system, cache and ART/Dalvik. Often when flashing ROMs, things don't get cleaned out properly, and artifacts will remain. Most ROM developers will include the instruction to wipe, which brings us to the next point;
5) Follow the directions exactly. Do not freelance unless you know what you are doing. That means flashing kernels, modems, bootloaders, etc. Follow the instructions in the order they are presented. If you don't understand any of the instructions, don't proceed until you do.
6) Perform a factory reset after flashing a new ROM but before booting.
7) Before rooting, I strongly suggest that you move anything you have stored on internal storage such as pictures or music, off the phone. Before you flash your first ROM, format the internal storage. The root process involves Chinese software and if you're not one who keeps up with the news, the Chinese are notorious hackers. Make sure you get all of the cooties off your phone.
8) It takes a long time for a phone to fully boot once you've flashed a ROM. Usually, it's over in about ten minutes but twenty minutes isn't unheard of. Be patient and resist the urge to pull the battery.
9) If you can get into recovery and download modes, you did not "brick" your phone. Contain your panic and think things out. The best advice I can give is to try to get back to the last time things worked.
Q: How do I know whether to use ODIN or flash in recovery?
The developer will usually tell you. But, if the file you're flashing has a ".tar" or ".md5" extension, it's flashed in ODIN. Often that file is zipped (extension ".7z") and needs to be unzipped. If the file has a .zip extension it's flashed in recovery.
Q: What is Odin?
A: Not the Norse god in this case. http://forum.xda-developers.com/gal...08-2013-odin-3-09-odin-1-85-versions-t2189539
Q: What is TWRP?
A: TWRP is what's known as a custom recovery, which is what allows you (for the most part) to flash custom ROMs and packages to your phone. Each build of TWRP is device-specific. Make sure you downloaded the correct version for your device. http://www.xda-developers.com/how-to-install-twrp/
Q: What should I do if I'm having an issue with the ROM?
A: PLEASE don't just complain that something isn't working. See if you can fix it yourself; maybe it was something you installed or changed? If it's not unique to you or even a clean flash doesn't fix it, then you should look into providing some logs for the dev. Check out LogCat. Ask the developer how they want the log delivered.
Don't complain if you dirty flashed the ROM (meaning you didn't wipe /system and /data before flashing -- leaving internal storage and SD card alone is perfectly fine). While it's possible your issue is something wrong with the ROM, the developer will just ignore you. Also don't lie about having done a clean flash. It's pointless, and the developer can probably tell from any logs you provide that you actually dirty flashed. It's not fair to others if you take up their time by helping you try to fix a problem that can be solved by flashing the ROM the way it was meant to be flashed.
Q: Things on my screen are too small/large.
[SIZE="3"[I]A: You can actually change what's known as the DPI. Here's a method for that for the Note 4 on TouchWiz: [url]http://forum.xda-developers.com/note-4-verizon/development/solution-dpi-change-camera-dialer-t3422699[/url][/I][/SIZE]
[SIZE="4"]Q: I really like the ROM I'm using. Is there something I can do to help the developer out?
A: Luckily for you (and the dev), there is. Many developers will have a DONATE button in the sidebar on their posts. Remember, this is the only way most of them get anything from what they do. Developing these ROMs is usually done as a hobby, and considerable time and effort are put into producing something for you to use on your phone.
If you can't donate (or don't want to -- it's understandable), hit the THANKS button on the developer's posts. It's a nice gesture that shows you are interested in their work and that you would like to see more.
Q: What's this Xposed thingy I've heard about?
A: Xposed is a framework that allows almost unlimited customization and feature unlocking. As such, it is not something to play with lightly. This is the forum devoted to Xposed. This is where you'll find the framework, installers, and the modules.
@wanam has done much of the development for Samsung phones. Here's where you'll find his work. Since his is made especially for Samsung ROMs, I strongly recommend sticking with his base until you're more comfortable with using Xposed.
Q: There are so many downloads for Xposed. Which one do I use?
A: As always, RTFT (read the f'ing thread). However, here's a shortcut. Note 4 phones are ARM. Version 86 is current. Use that for AOSP based ROMs. Use the "alt" version for TouchWiz based ROMs. You need both the framework and the installer.
---------------------------------------------------------------
It's not very much so far (it's hard to come up with this on the spot), but I hope you'll all help out by posting the other frequent questions you see around these forums.

As always, RTFT (read the f'ing thread). However, here's a shortcut. Note 4 phones are ARM. Version 86 is current. Use that for TouchWiz based ROMs. Use the "alt" version for ASOP based ROMs. You need both the framework and the installer.

10) Douger does not use Titanium Backup to restore his apps, especially if he's flashing a different ROM than the one he was on when he created that backup.
11) If you didn't do a full wipe before you flashed that ROM (dirty flash) do not complain about things not working properly on the developer's thread. Do send the developer a logcat so he can look into the issue.

From now on, I'm just going to link all questions to this thread. If they're too thick to use it, tough cookies. It'll be all they get from me. I just reported this post to see if we can get it stickied.
And thank you for fixing my boo boos.

What you need to know about ODIN.
Everything you wanted to know about TWRP but were afraid to ask yo mama. TWRP is phone specific. Don't try to flash any old copy of TWRP.
Giving back to the community. How to logcat.If you're having an issue with the ROM you're on and you did a clean install, generate a logcat, then PM the developer and ask him how he'd like it delivered. It's basically a system dump which shows where errors were generated. It's helpful to narrow down the bugs. Don't fib about doing a clean install. The logcat knows, and is worthless to the developer.
How to change your DPI Thanks, @charly211297!
Almost forgot the most important thing: If you enjoy using the ROM or kernel and have gotten value from it, please consider sending the developer some beer money. Most of these guys spend considerable time in development and fixing bugs. Remember that no one here gets paid for what they do and if nothing else, hit that thanks button.

[Q] AT&T SG4 SGH-I337 Slow

Hello. Sorry for the noobie question. I tried to search the forums, and I did find the noob beginner guide, but I still wasn't sure, so I prefer to ask before I screw up my phone lol.
I have the AT&T SG4 SGH-I337 Phone. It was fine before it was upgraded to 4.4.2 (I didn't want to upgrade, but it did it on its own one day). Once it went to 4.4.2, everything is just DOG SLOW. I mean everything. In Car Audio takes forever to connect, phone calls takes like 5 secs to answer, even after I press the answer button. To unlock the phone I have to press the code 2-3 times, as I can see the keys I press is lagging behind.
What I wanted to ask is this: How can I bring this phone back to the previous OS? Or How can I modify this phone to a stock OS, where all this bloatware crap is not installed?
All I care for is my Bluetooth, in car audio and calls and have a phone that's fast enough as it was originally.
can someone point me to the right thread where it gives me step by step instructions? Ive never modified a Samsung Phone before.
I found this thread, but wasn't sure if its the right one for my phone.

Believe you will need to Odin back to NB1 then update to NC1

Read the OP on the link very well and generally not a good idea to use links outside xda unless you are 120% sure of what you are doing--good luck--

I would suggest getting the Google Play Edition rom as stock android is much better optimized. Tutorials are available on the all things NC1 post. This will require root and installing a custom rom. Your warranty (if still applicable) will be void if you choose to do this. Regardless, the software on the device is not well optimized and the touchwiz UI is unnecessary imo. The GPE rom also does not have the samsung or at&t bloatware.

Use the "All things ATT" link rugmankc gave you. In the first posts in that thread you will get links to the root method, safestrap, and a list of compatible ROMs. A few thoughtsL
1. Before making any changes to you phone, charge it to 100 %, unplug the charger, and let it sit idle for some number of hours. Then check to see what services are using most of the power. For a while my own 4.4.2 GS4 was slow, and it turned out to be google play framework services bogging things down, and this showed up as an excessive battery drain during idle. If you phone uses more than say 0.5% battery per hour when completely idle / screen off (but with cell and wifi on), something's up. Fix it and maybe your problems will resolve.
2. Next step: back up any data / photos etc. and do a factory data reset from the settings menu. After it has been reset, perhaps whatever problem is going on will be cleared up.
3. You don't need to root the phone to ODIN a stock firmware (NB1 then flash update to NC1). Links are on the ALL Things ATT thread. This should take it all the way back to proper NC1, bypassing any mess that might have happened if you got a corrupt flash during your OTA update.
If the phone still performs so poorly as you describe after a flash back to stock, there's a problem that's more than the OS/ROM. Sure, the stock build is a bit laggy and bloated, but it's not so bad as what you are seeing.
If you find a restored stock ROM to be better but still laggier than you like, I have had good results with the GoldenEye ROM, flashed according to the instructions in the ATT thread. To flash, you must first root and install safestrap (selinux mode changer set to permissive may be required). You then boot to the safestrap recovery, wipe everything but the SD card, then flash the rom, SuperSU, ATT Module, and ATT BuildProp/APN. That should get you up and running on a new ROM.
I'm a died in the wool geek but I read through this forum and others for two weeks before attempting... but I'm very happy with the phone as it works on GoldenEye. I'm on V36, but V38 is current.
Good luck

Thank you very much for your help. Yeah everytime I redo my phone, from scratch, it works OK for about an hour. Then bam, it goes back to being a low pain in the rear. This is ONLY after the phone upgraded to 4.4.2. I didn't choose that upgrade, actually I didn't want to upgrade, but OTA upgrade took over and BAM, I got screwed.
OK I just installed the Safestrap and rooted the phone. Now I gotta figure out the rom part.
Im still going thru that link that rugmankc gave me above. Now im trying to figure out how to change the OS, since I just rooted the phone. I have to do this. Ive gotten really really tired of the phone being so slow, I basically give up on many tasks that I need to do, just cause its too slow.
Ill update once I get it figured out, hopefully I wont brick it, that's the only thing that im afraid of.
Don't remember, did you consider Odin back to stock and start over. If not, whatever was causing the slow downs may still be there. Could have been a bad update.
Read the SafeStrap thread by HashCode carefully. I read the OP 100% and last 30 pages or so of thread and don't even use it. It is complicated to me. IE which slot to flash to stock or rom. I think stock, Flash Modules. Install Selinux and set to permissive. And using correct SafeStrap. Gives me a headache and I am not even needing to use it--
Good Luck--as mentioned just backup whenever you can before moving to next major step. :good::good:

Thank you. Actually I backed up my phone already, as I reformatted it last night again. I don't know how to Odin back to stock. What is that? Is that a stock Android? Sorry I don't know.
Thanks...
It's in the same All Things ATT, MK2 thread under Returning to Stock Odin. An option if you still have issues. Takes you back to stock NB1, firmware and all. Kinda like your update, but think you may have got a bad update. Other options are to wipe internal in case bad stuff still there. Frankenscript was pretty thorough--:good:
SafeStrap is how you are going to flash a new OS/Rom. You can't flash custom kernels and aosp roms unless TW based like a couple GPE mentioned.
Read/Scan the two mentioned threads, as in OP and first and last couple dozen pages. Probably the last are more important. You will see folks asking the same questions you will eventually ask. I have read thousands of pages over the years and it has kept me out of trouble--most of the time--

Man, that link really got me confused as heck lol. Ive been reading that link the entire weekend and still im a bit confused.
I rooted the phone with towelroot. Ive installed SafeStrap, but it worked the first time I ran it. Now if I want to run it again it crashes my phone. Not sure what that is about.
Either way, now my understanding is that I should be able to download a rom for my phone and flash it. From that link that I was given, its very confusing.
Could someone PLEASE PLEASE help me here with this?
My phone is an AT&T US SG4. Here are the details:
SAMSUNG-SGH-I337
Android 4.4.2
BaseBand I337UCUFNC1
Kernel Ver 3.4.0-1125940
Build # KOT49H.I337UCUFNC1
Which ROM can I use for my phone? As long as its stock, I don't care which version, Google Play ROM or CY or Golden, whichever, as long as I get rid of this crappy Samsung and AT&T stuff off my phone.
Could someone please help me out here? I know that link says everything, but jeez, im trying to make sense of it, and so far, I got the phone rooted, but just cant figure out the ROM part.
Thanks...
I can't help with specifics as I don't need SS.
Make sure you have correct SS--3.72, afaik
Flash, I believe, to stock slot not rom slot but confirm that
Install Selinux app from Play and set Permissive--afaik
The above items are things people get into trouble with, so reconfirm them
Just keep reviewing the thread and the SafeStrap thread in Dev section by HashCode. Maybe go back more pages from end of threads as you have time. You can post in All things thread now for help and at 10 posts in Dev section. It will come together in time--:good:
Flash roms only for you build, think there is a list within that thread or another one in General or Q&A.
iB's Goldeneye 38 is good and you can use the Aroma to select SafeStrap and the Slimmed down version.
Read his SS flashing instructions first.
Make sure you use SafeStrap recovery to wipe ALL--System/Data/Caches before flashing--:good:
Cornelp: Having recently been through all this, I wrote up a short summary with some links for another user, and it might help you to look through it. It's an overview written from my end-user perspective, not a replacement for the detailed posts the devs have done.
However, based on your description, I would say the best thing to do is ODIN back to stock because I have a sneaking suspicious you got a bad OTA flash. It happens. Going back to stock will be the best way to eliminate that as a source of problems. Learn how in the All things ATT thread OP.
Best of luck to you!

Complete instructions here:
http://forum.xda-developers.com/showpost.php?p=51130818&postcount=5
Basically, download ODIN to your PC, run it, get phone into download mode, connect phone to PC via USB, in ODIN select the NB1 file, tell it to start. When done, reboot phone. Then flash the NC1 update from an SD card using stock recovery.
A good pictorial description of how to flash can be found in this S3 thread here:
http://forum.xda-developers.com/galaxy-s3/help/guide-odin-flash-guide-t1671969
Though for a different phone (the S3, not our S4), the process is still the same.
Good luck. I'm headed off to a work trip and won't be on the forum much this week!

Thank you all. I was able to revert back to the NB1 stock, but it failed the first time. I had to download and install the NB1 Rootable Odin. For some reason, the NB1 Odin didn't work, but the Rootable one worked.
So im glad I was able to go back. Now I just gotta test it and see if it does slow down as it did before. I will post update, in case anyone else has the same problem, maybe this would be a good solution.
Thanks again to all of you guys, really appreciate it. I really hope it worked.

Verizon Note 4, I have Root and BL Unlock. A few questions within.

So after blowing off the second half of my duties at work today, I managed to allocate enough time to get my SM-N910V rooted.
I have a few basic questions about what I should expect to see happen.
Allegedly, Verizon is rolling out an OTA upgrade to 6.0.1 Marshmallow sometime soon. Now that I have 'custom' boot and root achieved, will my device still receive and adhere to this OTA upgrade?
I have not applied any custom ROMs to the device. All I have done is follow the steps on this forum to unlock the bootloader and permroot.
If yes, cool!
If no, could someone please share with me a uniform resource identifier (lol) that links to a guide for installing CM13 to this device?
I will use my mind to beam eternal luck at anyone who helps me out. Thankyas.
Have you ever used Odin?
If you have twrp just load onto an sd or the phone and make sure to clear cache and wipe.

Yessir Mr. Nasty,

Just to clarify, you're saying that if I boot into TWRP again and clear the cache/wipe, I'll go back to factory settings and get the OTA?
If you have a microSD card, use TWRP to backup all of your current data to it if you'd like to preserve it and have something to restore if anything goes awry. Download a custom ROM zip and whatever other zips you'd need for that particular ROM, and put them on the card. Use TWRP to format data and wipe everything EXCEPT FOR THE CARD, and then reboot into recovery mode again and open the TWRP install menu.
In that menu, navigate to external_sd (or whichever root level folder it is that contains the strings "ext" and "sd", referring to the microSD card), and select the zip or zips (in the proper order) that you want to flash. Then flash them, wipe cache/dalvik, and reboot.
I wouldn't stay on a stock ROM if I were you. You might avoid getting the OTA, but you're guaranteed to avoid it by running a custom ROM. JasmineROM seems to be the go-to ROM for stability, but hsbadr's CM13 builds are very functional.

I dont know what everyone is thinking, but OTA will not work with rooted device. It will failed and in most case you will nee to flash full stock rom to fix it, then your bootloader will locked again. The best bet is to wait until Samsung released the rom and Dev here will modified it the right way so you can flash with TWRP.

Honestly, don't bother with CM13 yet. It's buggy. I was on it for a short while, tried a couple different builds but I got sold on the Note 5 port which is on 5.1.1. If you have any apps that don't allow mock locations, they won't work on any 6.0/Marshmallow ports (i.e. CM13) from my short experience. I could be wrong. I couldn't find a way to allow mock locations on CM13, so I went somewhere else.

I think CM13 is worth giving a chance.
I'm about 90% sure the MM update will come with a new bootloader (a locked one). I highly advise against trying to accept it if/when it comes. Someone here will tear it apart and make odin flashable images to get us on 6.0.1 TW rom. Until then, flash TWRP and CM13. I've been using it daily and it's one of the better CM roms I've used on any device.
Also look into Dual Boot Patcher so you can crack flash roms without affecting your primary one.

I might add to that storing a copy of that backup on another device... your desktop computer, perhaps, so that if something really goes bad and wipes your sd card, you still have a backup.
Do not, no matter how much your phone nags you to, take an OTA now that you're rooted. The odds are good that they've closed the exploit used to get root.
If you're looking for stability, Jasmine ROM is the best that I've tried. It's not being supported anymore, but it really doesn't need it. Everything works. I froze, then deleted every single Samsung and Google app that I don't use and it is just smooth.
CM 13? The last I looked, the camera doesn't work well, Bluetooth is problematic, you can't set your sd card as internal storage and a few other niggling issues. I've been doing this since my Droid Incredible and have found that ROMs ported from other devices will have issues until the developers marry the software to the hardware. I'm now waiting for the official Marshmallow to drop and let the developers take a crack at it.

Bluetooth is flawless. I can't see why anyone would set their sd card as internal (defeats the point of being able to move info between other phones and/or computers). Camera works very well (for CM). I've had very few issues with taking pictures. Recording video doesn't work for me. I've modded every phone I've used (I've owned many that I wouldn't carry due to no root) since the Eris and this is IMO the best CM port ever.

I am using PaulPizz 5.1.1 ROM and it's working almost flawlessly. I'm happier than ever with this phone. I want to wait for the OTA 6.0.1 to hit and the teardown of that to begin before I switch.
I'll look into dual boot.

Need Beginner's Guide, so Custom Rom can be installed

***UPDATE***
Thanks to reply, I have now successfully done everything I set out to do, and created follow-up guide!
You can find it HERE
Original Post below:
Hello Everyone!
I'd like to start off saying I used to have a Nexus 4, with TWRP and Lollipop-based CyanogenMod. I was able to install this all by myself, and keep both TWRP and the ROM updated. I also flashed custom radio to unlock the LTE capability on that phone. My tool of choice to help customize the phone was Nexus Root toolkit.
I was able to follow guides posted long ago on these forums, to do what I wanted with the Nexus 4 back in 2013/2014, but it seems I'm not so capable these days. I've hit such a roadblock with lack of root and constant stutters/slowdowns with everyday use on my current device, the Axon 7, that I must get away from the stock software. I heard it was not so easy with other devices, and while a few devs have posted wonderful guides for users, it's just not enough for a true beginner like me. From skimming guides posted, it seems like devs already expect you to have installed custom recovery, or unlocked bootloader. Then when I try to do these things, so I can move onto custom ROM, it seems the guides are out of date or just not step-by-step enough for me to use, and I don't want to take a risk and brick my device trying things that I'm not sure about. I'm a power user through and through, but not so up-to-date or knowledgeable enough to be able to follow the guides already on the forums. Consider me 1 out of 5 on tech level for Android software.
Here's the model/software already on my device: Stock everything, from bootloader and recovery, to ROM.
Model: A2017U, Nougat 7.0 on B15 ROM
What I still need clarification on:
with my device already running on nougat, do I need to install the nougat universal bootloader/radio I saw in earlier guides?
will LineageOS have any downgrades in regard to audio quality, on either the headphone output or speakers?
will my ROM of choice have Daydream VR support? if not what would be needed?
this is not a big deal, but do I need a special app or entire custom ROM if I'm interested in a temporary unroot to use apps like Android Pay?
Here's what I want on my device: TWRP, LineageOS with root.
If anyone, expert users and devs alike, could reply with current known-good info about the following, I and a lot of other users would be eternally grateful:
unlocking the bootloader, installing TWRP, and LineageOS, in a stupidly long but simple step-by-step process.
Quick follow-up info:
What I can do so far: download current LineageOS nightly, correct version of root .zip, and TWRP from official websites
NO, I'm not good with using ADB on Windows to get things done. I had to ask a friend to help me install it on windows, the guide he sent was much easier than the one i was using, and he still had to walk me through how to use it once installed to help me unlock bootloader/root on another device, Zenphone Zoom if anyone is interested.
PLEASE, don't link me to other guides for any part of this process, if the steps are thorough and relevant, please copy here, of course with all due credit given to original poster.
Feel free to let me know if more info about my knowledge level or device is needed to help you work on my request.
Thanks for reading, here's to several years more of everyone enjoying this wonderful device!
ok there is three real steps, but it can be aheadache, mainly because you didn't unlock before going to nougat.
Step 1. Downgrade to B29 Marshmallow - go here https://www.zteusa.com/axon-7/ and on the support tab in software updates is a full B29 software package. Download it, unzip it once, then put the update.zip file on your SD card.
- on the phone, in developers options, turn on OEM unlocking (it is needed to flash from sd card)
- boot phone to recovery, choose update from sd card, pick the update.zip from the sdcard, the phone will flash the B29 software. It is a bit slow, let it do what it needs to do.
Step 2. Unlock phone and install TWRP - go here https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514 download the miflash program, fastboot unlock program, and twrp for B29.
- instructions are all there, just do what it says.
Step 3, Install LineageOS - https://forum.xda-developers.com/axon-7/development/unofficial-lineageos-14-1-zte-axon-7-t3545679 very straight forward. Don't forget to install first the bootloader, then the rom, then gapps.
What makes this so hard is not being easily able to unlock in nougat. Most of us here unlocked way before marshmallow
No need to downgrade to b29.

I was thinking this too. Should be as simple as the steps below
1) Flash signed twrp using axonroot tool - this pry's open the door
2) Using twrp, flash fastboot (b20_fbop or something?) - opens door wider
3) Enable usb debugging and oem unlocking in developer options
4) reboot to fastboot/bootloader mode
5) fastboot oem unlock - door is now wide open
Done.

Is that a "should work" or "does work" because I'm trying to root and install LOS also on stock non rooted nougat Axon 7 and so far I've gotten nowhere and no one seems to be able to give me a list that says Yes this works

I followed the instructions and is apparently in a boot loop. Initially it was working but now it is not. I can't even wipe the device to start from scratch. Is there another ROM available to try?

Ok, I've edited your post to clear some of the clutter and numbered everything so I can answer everything.
1. No, bootloader updates are only for users who haven't updated to B15 (through official means)
2. Only audio issues are with the front facing speakers. The way they sound is if you turn them up to 100% and then push it even higher to like 140%. So if you keep it at about 71% they sound normal. Check this guide here to get even better quality on overall sound (headphones, speakers)
3.B15 and LOS both work with Daydream. I currently use LOS with my Daydream headset currently.
4.Magisk with this kernel here. Currently have fully functioning Android Pay with LOS.
5. This is a big problem. If you're not comfortable with ADB you should maybe rethink messing with this phone. EDL mode (which is how I flash TWRP and subsequently the B20 bootloader to unlock) is very similar to ADB and the tools needed to flash in EDL can brick your device. Learning how to use ADB isn't bad but it's good as a fallback so you're not relying on strangers to help you out in a pinch (which most will, I just like having the ability to do things mostly myself).

I'll keep on saying this as much as I need to, I get where you're coming from. There's a lot of data about the correct way of doing things. Best thing to do is read and search. When I got my phone B29 was the new hotness and there was a bunch of older data floating around that I had to sift through. But I did it, I sifted and found my own way and combined two different methods to get my phone rooted and flashed with LOS. Honestly, the trial and error, the searching, the sifting is totally worthwhile because while this device is /DIFFERENT/ compared to methods for HTC and Samsung products, it's not harder. It's better to get yourself properly antiquated to the device you plan on flashing/hacking/rooting because there is /always/ a chance for bricking. Then another thread will be created asking for help to unbrick. Take the time, read now, read everything, understand your device, then push forward.

I quoted this because this thread is like the third I've seen in the last couple days. But to offer some help, this is the guide that I've followed with two phones one running B29 stock and one running B15 Stock. It remains the same because of the use of EDL. It's also good in case you want to go back to complete stock (which at the time was speculated would brick your device) but I read between the lines and discovered that it's just not a big deal. Once you get TWRP installed, make sure your Data partition is EXT4, flash LOS, flash GApps and you're good to go.
The hardest part of the process, is getting your drivers to be recognized properly for the EDL flashing tool to work. Anti-Virus softwares tend to throw false positives with tools like the EDL Flashing tool. I installed a fresh copy of Windows 7 JUST to have a flashing station ready JIC. Once I did that, smooth sailing.

EDL mode (which is how I flash TWRP and subsequently the B20 bootloader to unlock) is very similar to ADB and the tools needed to flash in EDL can brick your device. Learning how to use ADB isn't bad but it's good as a fallback so you're not relying on strangers to help you out in a pinch (which most will, I just like having the ability to do things mostly myself).

I quoted this because this thread is like the third I've seen in the last couple days. But to offer some help, this is the guide that I've followed with two phones one running B29 stock and one running B15 Stock. It remains the same because of the use of EDL. It's also good in case you want to go back to complete stock (which at the time was speculated would brick your device) but I read between the lines and discovered that it's just not a big deal. Once you get TWRP installed, make sure your Data partition is EXT4, flash LOS, flash GApps and you're good to go.
The hardest part of the process, is getting your drivers to be recognized properly for the EDL flashing tool to work. Anti-Virus softwares tend to throw false positives with tools like the EDL Flashing tool. I installed a fresh copy of Windows 7 JUST to have a flashing station ready JIC. Once I did that, smooth sailing.

I've already used EDL mode from that page to put a fresh copy of stock nougat to, among other things, reduce the potential issues upgrading causes. So all I should have to do is flash B15-NEW_TWRP (Nougat) from that page and then fastboot unlock?
from there reset data/cache, flash custom ROM.
flash gapps
reboot, install apps.

Thank you for the guide, but I managed to get everything done without having to downagrade from Nougat. I was having issues with my Windows variant recognizing my phone after drivers were installed so I used Linux Mint 18.1 and everything went smooth as a whistle. I think the mods should pin your thread post.
I followed the rootjunkie YouTube videos, worked perfectly and the files were all available.

How to upgrade from 6.0.1 to 7.1.2?

Hello guys,
I'm a complete novice on rooting or flashing cellphones, I'm just a regular user of a Moto X Play XT1563 (bought in Colombia / South America) that wants to upgrade to Nougat 7.1.2.
I want the 7.1.2 just for a regular usage: apps, internet, bluetooth, NFC, camera, GPS, phone calling and of course a good battery performance.
I want to kindly ask for your guidance in all steps required for the backup and upgrade, so if you can please guide me about the whole process I will appreciate it a lot.
Thanks

Hello!
In short, the process for our phone would be...
0. Backup data.
1. Unlock bootloader. This will void your warranty. Unlocking bootloader allows you to use fastboot mode to flash custom images to your phone from a computer.
2. Flash TWRP Recovery. This is done in fastboot mode. Once you have TWRP, you can flash on to or modify the system partition (and other partitions) of your phone on the go.
3. Format the /system partition to get rid of the existing ROM (stock in your case) and then flash whatever ROM you want. This is done using TWRP.
4. There's no fourth step.
Its pretty straightforward, detailed guides to each of the steps are available in this forum. You should use the Index Thread pinned on the General forum to get the links to the required guides at one place. Use the search if you encounter trouble. Then there's the forum to ask.

Thanks for your response,
I bought my cellphone two years ago so It already went out of warranty so no issues with that step, I already found the guide to "Unlock bootloader" but before I start with it I would like to ask if after that the phone will be unuseful? I mean, after unlocking the bootloader can I start the phone and continue using it? It's my only cell phone so I want to be aware if I will stay long time uncommunicated.
My second question is about the new ROM I will flash, I've no idea about what "versions" exists or where I can download them... so is there some kind of "most stable" version using Nougat 7.1.2? or some "ROM Reliable supplier"?
Thanks

Unlocking bootloader will wipe all your data (it will trigger Factory Reset on your phone). Other than that, your phone will be 100% usable.
Roms are available in Android Development and Original Android Development sections of this forum. Just check the threads that include [ROM] in their title. You have to decide for yourself which rom suits you the best - read its description and what users say in comments.

As said, after unlocking bootloader the device will be wiped- You will have to reenter your Google account and reinstall applications etc. Not a big deal.
Custom ROMs sometimes take a few iterations until some bugs here and there are ironed out. Sometimes it happens, in others one may end up switching to a complete fresh ROM. In such instances, you will usually have to make a "clean install" (i.e. a factory reset) and then reenter the Google account and reinstall everything again... It sounds irritating, but nowadays it's pretty much straight forward, and if you don't have hundreds of apps it usually is finalized in 10-15 minutes and is semi automatic.
Updating to a newer version of the same ROM sometimes can be "dirty flashed" (i.e. without wiping all your data) so in a couple of minutes you are set up and ready to go. More convenient, but if something isn't working right and you complain in the thread, certain chances are you will be politely asked to make a clean install first amd some users may flame or grill you alive for dirty flashing and complaining at that :laugh:
Most custom ROMs are usually based on either AOSP or Lineage OS (aka LOS) with some custom modifications. The first post in a ROM thread usually mentions all the rich features (or lack of), how to install (pretty much the same: make a backup in twrp, wipe data/system/cache/dalvik, flash ROM zip file, flash Google gapps zip, flash some additional optional zips such as supersu/magisk/whatever for root etc). Then some download links, faq etc.
It's good practice to read the first post (aka OP), then at least the last page to get a feel of the ROM (e.g. see what others are praising or complaining about this or that), then search for specific stuff that may concern you. For example, some ROMs had this cellular data bug that it got disconnected and required restart. You may decide this os crucial for you and choose another ROM, others may use the device for other things and couldn care less about cellular data bug...
Enjoy, it always feels good tp flash a new ROM, a new version . F!ck LeMoto for delaying the update for so long- You may have been waiting for update to Nougat as early as last year's November or October. Well, on custom ROMs it's here for many months!
On the other hand, they usually say stock ROM is more stable, and in many cases it is also true...
Now you know more or les what you're dealing with: free choice vs. waiting forever.

Thanks for your thoughts,
After reading here and there I finally was able to flash AOSP Extendend v4.4 on my cellphone, it seems to be working fine.
As I said I was not looking something specific I was just annoyed of waiting so long for the official update (it seems it will never happen) and wants to be in touch with Android Nougat, maybe now I will use my piggy bank to save for a Pixel phone
Thanks guys for your guidance

Hi,
How it is working? Did you found any bugs? eg. problem with battery, with mobile data, lte, camera?

Hi all. I'm new to rooting can any one please help and point me to the right tutorial to root a samsung s7

Hi All
Looking for a best tutorial to follow and the right one for my phone really don't want to brick it, obviously :/. as there seems to be a few versions for the S7
I have the following: S7 android 8.0.0 SM-G930F not sure what else I need to know! I'm in the UK so I assume UK phones come with Exynos cpu's
and as far as I am aware android 8 is Oreo! but when they say Stock Rom I assume they mean the same as what came with the phone the original rom?
if so is there an alternative stable rom without the crap included or is it just as simple to delete every thing you don't want now it's rooted! and does that mean if I reset the phone its back to normal with all the crap included! or is there a way to keep it rooted even after reset! and should anything be disabled I.e prepare the phone before attempting to root like any kind of auto encryption that needs disabling and just one more question
if at anytime the rooting process hangs for a ridiculous amount of time when should I throw in the towel! and what are the chances of retrieving the phone back to original state! or does a dirty shutdown brick it?.
I started the root process but failed at first hurdle!, followed instructions install Odin3_v3.13.1 but when I connected the phone nothing showed up in Odin? though I will have another go just to confirm I followed it correctly, I'll update this when it's done.
this was the tutorial I followed:
Easy 4 Newbie [Root Guide]SM-G930F, G935F, G930FD, G935FD (Samsung Galaxy S7 Edge)
Warning ! Please note that the official TWRP for Nougat on Galaxy S7/ S7 Edge is not available yet but based on my experience the Marshmallow version is working on Nougat. By installing a custom recovery on your S7 and S7 Edge and rooting it...

I know alot of questions I would really appreciate any help and clarification on the above.
many thanks

Look pal, rooting the phone is just like being an adult, it means you will get rid of Samsung's "Child Care".
Yes, UK models use Exynos chip, but you have to be sure, look at your baseband version, if it is G930FXXX, then you are good.
ROMs are in two shapes:
Stock-based: These are just like the one you are using, or other Samsung phones does, like Samsung Experience, One UI, TouchWiz. Maybe MIUI and FlymeOS will come into account, as there are ROMs based on them + Samsung's.
AOSP: These are pure Android ROMs, with few modifications to the core, but keeping the UI as close to the source as possible, Google & OnePlus phones come with a near-to-pure operating systems.
Changing a ROM is not risky, as long as you follow the instructions, without any unaccounted improvising.
Before you install a ROM, read the working and bug list, to make sure you are installing something you have an idea of.
You need to install TWRP recovery (or any other one you like), and format data, in order to be able to travel among ROMs and/or root your device.
Formatting is only required because the phone is forcibly encrypted, and TWRP can not decrypt it, at least not for this device.
Rooting is simply about flashing a 5-MB file, Magisk, then rebooting to system, no need to wipe data.
No need to do any additional steps, unless you are trying to hide root from some apps and/or pass SafetyNet.

Hi Mohamedkam000
Thanks for replying. I'm not confused about why I want to root the phone. I'm just trying to understand the inner workings and the risks as I'm not as clued up with phone OS's as I am windows. I don't care about warrantees or hiding the the fact it's rooted I just want a clean rooted phone free of big brother well inside at least I know you will never completely keep them out but making it hard is a start lol.
Thank you very much for all the above especially on clarifying about the roms and the reason TWRP formats due to encryption nice one
My Baseband version slightly different though it's G930FXXU8ETI3 not sure if having a U instead of a third X makes any difference!
and I posted wrong tutorial I'm actually following this one below again not sure if that matters.

It doesn't matter which version of Android you are using, root is the same.
However, on stock ROMs, it might sometimes get rough, as you may end up with Wi-Fi not working (happened to me Q1 2020).
If you really want to learn how Android OS works, then rooting the stock ROM is not your way.
Try AOSP ROMs, preferably start with Oreo ones, you can root in 3 common way, LineageOS SU Add-on, Magisk, Super SU.
But before you tickle your phone, you have to make a backup of your current device, of every partition, EFS is the most important partition, so make sure it is safe.
Baseband version doesn't matter a lot, unless you're paranoid with updates, it is sorted alphabetically, each string on its own.
The phone is more similar to a linux machine than to a Windows PC.
Edit: To root stock ROM, you have to flash dm verity, so you don't end up encrypted again.

Thanks again for clearing quite a few things up I thought rooting stock rom would have been far safer way forward wow how wrong was I! but I guess I am just trying to find any kind simile to windows in any way but as you pointed out again it's more like Linux which again I've only played around with ubuntu and mint for a short period so again not to up on Linux lol.
It's funny I was just reading up on AOSP ROMs then got your message. I see they have a stable but not complete! Android 10 not that I would consider it need as I need a stable OS so Oreo is fine for me.
I have backed up phone using Smart Switch on the PC I assume that copy's every thing that's needed, I reset the phone in anticipation all be it prematurely but at least it restored all my data so if anything that was a good test of the back up at least .
I will have look at some AOSP ROMs and see what's involved there, I'll check out their tutorial hopefully it will include the whole process including root.
I gather by your comment using a AOSP ROM you don't need to use dm-verity or will that still be needed!.
The first thing to do is to flash (install) TWRP, it's a custom recovery (think of it as a mini OS that can boot before Android), that will be the base for any of your future tinkering.
Here is the thread, read the FP carefully: [Recovery][Exynos] Official TWRP for Galaxy S7 (herolte)
Once TWRP installed, you can do many things:
Install addons like Magisk. Magisk is the tool you use to obtain root. Forget SuperSU, its outdated, and don't works in modern versions of Android.
Install a custom ROM (this subforum is the perfect place to find them).
Backup & restore an image of your current ROM (very useful).

I can't even get Odin to recognise my phone it just wont pick it up I have Samsung driver installed and I have reinstalled many times I found an article claim to have a workaround but that was BS just selling some other app I even change the driver as described on there page,

AOSP ROMs are pure, you can't say they are not complete. They are complete, and what OEMs do, like Samsung and Xiaomi is just a customization that you can do, too.
It is preferred that when you take a backup, take it with TWRP, just to ensure you backed up phone's partitions, along with "EFS".
The root procedure on Android 6+ is done by patching the Kernel (boot.img), so unless you take backup of that, you cannot keep root.
There are stable custom ROMs, custom ROMs are meant for custom adjustments, however the stability depends on your phone, and the way you use it, you can compare AOSP vs. Stock and see the difference.
AOSP ROMs doesn't need dm verity, well, at least not if the developer did not mention the encryption part.

Some of the roms I have looked at mention external touch buttons at bottom of phone do not work or something else in the phone I'm just reading their comments.
I understand about the stock & custom rom's now that's not my problem at least not at the moment as I am miles away from choosing a rom! as I can't even get out the starting gate!. I can not get TWRP on my phone as the only way I can see to get it on a unrooted! phone is to use Odin but as I said Odin doesn't work at least not for me it does not see my phone. I would love to take a back up using twrp but that won't happen until I find a way to get TWRP on a unrooted phone. what crazy paradox is this!. you can't root phone without twrp installed and twrp won't install on a unrooted phone!. that makes perfect sense.

Does your phone allow MTP communication? I mean can you transfer files when the phone is turned on?
Does the phone show any notification about a usb connection?
If not, then you have probably a bad USB cable, at least, or you have a hardware issue that can go as deep as a burned charging port.
If yes, then either your USB cable is not as fast as the phone requires, or you haven't installed the Samsung USB Drivers on your PC.
Unfortunately, you cannot root your device without PC, at least not since Lollipop.

I can't even get Odin to recognise my phone it just wont pick it up I have Samsung driver installed and I have reinstalled many times I found an article claim to have a workaround but that was BS just selling some other app I even change the driver as described on there page,

Which version of Odin are you using ?
Use this version (latest): Odin v3.14.4
Which version of the Samsung USB drivers are you using ?

Does your phone allow MTP communication? I mean can you transfer files when the phone is turned on?
Does the phone show any notification about a usb connection?
If not, then you have probably a bad USB cable, at least, or you have a hardware issue that can go as deep as a burned charging port.
If yes, then either your USB cable is not as fast as the phone requires, or you haven't installed the Samsung USB Drivers on your PC.
Unfortunately, you cannot root your device without PC, at least not since Lollipop.

Hi
Yes I can transfer files.
Yes phone asks to allow or block file transfer and it ohone shows up in Devices and Drives list and I can access the phone directory and shows up as Samsung s7 icon.
I will try another USB lead but the one I'm using is new and wasn't cheap but still a possibility I have had leads that weren't suitable for other things I was trying so it is worth a try.
Thanks

When I downloaded Odin this was latest one Odin3_v3.13.1 though I have doubts that one version update will fix this issue as I did not see many if any people having my issue so they all used Odin and I believe theirs are fine even with older versions! but as I said Mohamedkam it's worth a try I will down load that version and give it a try.
As for the Samsung usb driver I believe that is where I got mine
SAMSUNG_USB_Driver_for_Mobile_Phones no version visible under properties on file version 1.7.23.0.
The USB connection seems to be fine I have uninstalled then re-download and reinstalled a couple of times.
I can transfer files no problem it shows up as Galaxy S7 Icon with card and phone drive inside.
I'll update shortly thank you.
Update:
I just went to try new Odin and whilst checking my phone have seen I have Offical TWRP app installed? I have no clue as to how that's got in there! as Odin did not show phone so I could select nothing!.
In the phone I open app and if i select backup existing recovery it opens and Select Folder tab and under that Selected Folder: /sdcard Filename: Recovery .img and at the bottom of screen Root access required.
I just hope it's installed correctly!. it is showing in playstore my apps as well just to confirm. if this is now installed what should I do next Now not sure what tutorial to start following.
I am just going to try the new odin and see if it picks up the phone back soon.
OK Seem that it now shows up in the new Odin. at least I think it has! in the log window I see this: <ID:0/004> Added!!
I didn't see that before.
Would be grateful if you could tell me how to proceed from here!
Correct, you don't need he latst version of Odin or the Samsung drivers, bit it was just to be sure.
You need to be in download mode, but before, you must have checked OEM unlock & USB debug in developer options (mandatory).
I've written a tutorial with images here (in French):

As I said the older version did not show any kind of data what's so ever and the phone was in download mode. phone displayed "Downloading" which I believe it says that even if it's not doing anything! so a tutorial explained. I think it must have installed the Official TWRP app even though phone did not show up in Odin everything was blank however when I installed the new version of Odin like you suggested it then showed up as <ID:0/004> Added!!. so your suggestion work thanks for that and I did enable OEM unlock & USB debug I did long time ago.
I would check out your tutorial but unfortunately I don't speak French and translating instructions is too risky but thank you for the offer but I'll carry on look around still undecided on what custom rom to go for as I said some comments point out small issues and the developers also state certain things are not working so that is making it hard to consider one if you know what I mean.
Again Thank you for your input very much appreciated.

Take a note that, when you flash TWRP, you have to boot immediately to the recovery, so as to enforce its existence, cause I remember they phone has an original recovery backed up somewhere, and gets triggered when you reboot directly to system instead of the unofficial binary.
I advise you to watch guides on YouTube, it's more .. understandable.

I recommend to go with ALEXNDR ROM: zero bugs, everything works perfectly (it's based on stock ROM).
[ROM][G930F/FD][ALEXNDR] * U8EUE1 * DevBase v7.4 * Encryption support [Jul-10]
Important notes for Developers / Chefs !!! This ROM is NOT based on any other custom ROM. My work contains many original ideas and innovations that I introduced as the first in the ROM development (see "Changelist" in post #2). Of course, it...

Yer I read that but I've ended up with TWRP installed and did not do that process because I was unaware it installed until it showed up.
As I said I'll just keep looking for now I know I'll find one that works for me from start to finish.
and I've been checking youtube but wouldn't want to use any links their providing but it may help familurise myself with the whole process if i watch enough of them.
Thanks again for your help.

I click on "code" tab and then "download zip" and I placed that in a download folder on my sd card when I select it I get the above error any ideas as to why I am getting this am I downloaded the correct file?
