[Q] installing custom ROM on G2 [iPhone Refugee Thread]

Hello fellow XDA'ers,
I recently purchased the LG G2 and this is my first android phone. I'm coming from an iPhone 5 (for a multitude of reasons that are not applicable to this thread). I wanted to start this thread for people like myself who have no idea on how to install a ROM on an android device. There are various ROMs being released (verizon and ATT) and I would love a general walk through on how to install. Can anyone experienced point me in the right direction or offer any advice? Thanks in advance!

There aren't really any custom ROMs out for the G2 yet, just a couple of debloated ROMs (stock, plus root and minus carrier bloatware). Better ROMs will come, but it will be a little while. The G2 is just too new right now to have much out for it.
For a beginner, a few things you should keep in mind before rooting or installing a custom ROM:
* Be absolutely sure that what you're doing will work on your device before you do it. For instance, don't install a recovery image for an AT&T phone on a Verizon phone, unless you want to turn it into a paperweight.
* Read instructions carefully before you do anything. You should at least have some idea of what you're doing, so that in case something goes wrong, you'll at least have a chance of recovering. Don't just blindly follow instructions and hope you don't brick your phone.
* This *will* void your phone's warranty. If your phone dies after doing this (whether it's related to this or not), and you try to do a warranty exchange, they'll respond with something that is the same in English, Italian, and Spanish -- "No." On a related note, you are taking some risk by doing this. You could possibly mess up your phone. You could do things right, and an over-the-air update could conflict with what you've done and then mess up your phone. This is a risk you assume, not the developers of whatever you're trying to do.
* These forums, as well as #lg-g2, are for help. If you're not sure about something, ask. It's better to ask than to lose $600 because you incorrectly assumed that something would work.
Overall, rooting and ROMming your phone does give you more control. Just know what you're getting into.

There is risk involved yes, but it doesn't just straight up void your warranty in every situation. Depending on the carrier you are with and their RMA process you can get a perfect replacement with no hassle every time, and the carriers that do give trouble still have a small chance of going ahead with a replacement anyway depending on the tech you get. Many times for certain hardware issues it wont matter if you are rooted or not and you can still get a replacement as well. But choosing to unlock your device and do custom software for it you do have to accept responsibility that you could do something to break you device and that is your fault, not the manufacturer.
(skips these couple sections of text for just custom recovery and ROM install)
As for specific instruction, I cant really help much there. The instructions didn't really work well for me in the TWRP thread on XDA for installing, as there is nothing available when using Goo Manager, despite what that retarded thread says. I found better info on Rootz Wiki through a Google search on what to do, and even that was a bit wrong and I had to use some common sense to do things the right way. That common sense only comes from knowing how to use the command line and knowing how ADB commands work though, someone new to the process wont know that for themselves.
Looking over this thread for the newest info it looks like pretty much everything in this video should be correct and the download link for installing root should have everything you need:
http://www.youtube.com/watch?v=Y45SXPRb31o&feature=player_embedded
http://downloads.codefi.re/thecubed/lg_g2/root/ioroot6.zip
That gets root access on your device. You may or may not even want to do that. That installs root into your ROM you are currently running (stock), but you want to install a custom ROM and your custom one probably already is rooted to begin with. What you most likely want to do is just go straight to installing the drivers to connect your phone properly and use ADB to send ("push") files to your phone, then use something called "Loki" to bypass the locked bootloader and flash a custom recover to your phone. From there you can install ROMs perfectly easily. You can follow this guide in the link, but it doesnt give you links to the phone and ADB drivers you will need:
http://rootzwiki.com/news/loki-bootloader-bypass-twrp-recovery-come-att-verizon-lg-g2/
Right now there is not really anything but Clean ROM available, which is the stock OS that has a bunch of the "bloated" and unnecessary LG and ATT system apps un-installed. It cleans things up a lot and gives you a much better experience. In the future hopefully we will see some AOSP based ROMs that have a lot of the good features like "knock on", and those ROMs will be best since they dont have any of the bloat that the LG ROM has, and the AOSP based stuff gets a lot better mods to them and offers far better customization and tweaking.

Thanks for the info! I did not know that a most ROMs come rooted. So basically, I would not need to root then install a ROM?
I have an AT&T G2 so I would be installing the Clean ROM posted in the developers section. I would love the opportunity to debloat the phone and it seems like this is the best option currently. Enigma, are you saying that the knock on and off feature does not work with this ROM?

Installing ROM
Hello everyone,
I have rooted and have TWRP with the verizon phone.
How do i move a ROM into a phone so i can install it?
I have already made a backup of the current phone with everyone and copied it to the computer.

Put your phone in USB debugging mode under developer tools...hook up the micro usb to your phone and move the zipped ROM to the root of your internal phone storage.

[Q] Galaxy S4 SGH-i337m (Canada) rooting & flashing custom ROM

Hey everyone,
Please bare with me, this is my first time rooting & flashing a smartphone, so my knowledge on the topic is still limited even after some reads.
I also have the "misfortune" to not fall into the (apparent) easier route of having a non-Canadian Galaxy S4 where the model starts with "i950.." but mine being SGM-i337m. From what I've understood, the only reliable method I could use would be CF-Root, as described in this thread (OP's post), although the thing that bugs me, because I'd like to be able to install whatever ROM I'd like, is the line that says "[..] and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares [..]".
Also, which might be worth mentioning, my best bet is I'll probably end up flashing Cyanogenmod's ROM and they seem to have packaged installers, but I'm still worried it might not cover my model (if I take that route instead of rooting using CF-Root). From CGM's wiki under Supported Devices, there's a list that includes "jfltecan" (code name) for Canada, but I'm still hesitant. Do you guys think it covers Koodo (service provider) which I believe is owned by Telus (another SP) ? The last thing I want to do is brick my phone or have it unusable at the booting stage or whatever. And I don't mind reading, so any helpful links which covers this specifically would much be appreciated, although I don't mind an all cooked answer
Thanks

[HELP THREAD] Australian i9505 Users Region-Specific Help

Okay! I've been on this board for almost seven years, with phones ranging from a HTC TouchPro through to my current Samsung Galaxy S4 International GT-i9505. The ROM I'm on right now is (with thanks to AntaresOne) cm-12-20150315-OPTIMIZED-jflte, available from his thread, below...
http://forum.xda-developers.com/galaxy-s4/i9505-orig-develop/rom-cyanogenmod-12-t2943934
Everything works well - it's fast, has great battery life, the images, screen, text, video all look great, the sound for a phone call is clear and loud, ringtones are loud, the Bluetooth works with my Fusion car stereo and I can play video from it to my Samsung LED TV via wi-fi.
The intention of this Helper Thread is to have somewhere just for Australian users with Galaxy i9505's or i9505T's (the Telstra model) ONLY. That way, the discussions and advice shared is much more 'region-specific'.
On that note, I'll share my experiences with how to get the best out of your phone. Firstly, may I just say please read through these instructions carefully before coming to me with questions. I have spent the best part of five years tinkering with an i9000, then a i9100T, now a i9505 International. Also, there's heaps more help and advice to be found here on XDA-Developers, sammobile and a number of other Android forums, so I've always found it best to research as much as possible to take the very best information that actually works. No question is too stupid, unless you ask one that's been answered a thousand times already, like...
What's the best ROM?, What's the best modem?, How do I root my phone?, and Will rooting void my warranty?
And so, we start afresh with a Galaxy i9505, also known as jfltexx. Back up all your photos and music to your PC, and you'll find any number of apps on Play Store to backup your text messages and call logs. Titanium Pro is the best. It does need root access, but fortunately there are a couple ('SMS Backup & Restore' is one) that you don't need root to use. Seeming though 99.99% of everything you can do to upgrade your phone is best off being done with a clean slate, trust me when I tell you - BACK YOUR STUFF UP AND FACTORY RESET THE DAMN THING!
The most important step - BACKUP YOUR DEVICE'S EFS FOLDER!!! This is a location where information pertaining to your device's IMEI number and Country Code etc. are stored, and this folder can sometimes be wiped when you flash a new ROM. From Lollipop onwards, the way that's done is a bit different, but again there's plenty of apps and methods out there that will do this backup for you. Thing is, most often you'll need to be rooted, so...
You'll find throughout XDA a number of device-specific threads and posts about how to gain root access on your device. The fastest and easiest way to perform this task is to go visit Chainfire...
http://forum.xda-developers.com/showthread.php?t=2219803
The specific file you are looking for is called CF-Auto-Root-jflte-jfltexx-gti9505.zip. You use a nice little program called Odin - which just happens to be included in the package you've just grabbed - to 'flash' that into your phone. Yes yes yes, this voids your warranty and trips the Knox flag. Sadly, as much as you might find people who say that it can be reset, KNOX CANNOT BE CHANGED BACK ONCE IT'S 0x1!
Next, go and check out flatzki's thread at...
http://forum.xda-developers.com/galaxy-s4/general/i9505xxuhoa7-odin-files-100-t3043983
He's just got his hands on the Android 5.0.1 Lollipop Stock ROM for the International Galaxy S4 LTE, jfltexx. Thank him while you're there, and grab the ZIP file I9505XXUHOA7_OXAHOA7.zip. Create a New folder on your Desktop, then (using WinRAR or 7ZIP) extract the contents of the ZIP you downloaded into that folder.
Once you've done that, you'll be looking for a way to get rid of the 'dreaded' Yellow Triangle. Go check out...
chainfire's TriangleAway Thread
and follow the instructions from the Master himself. Grab the TriangleAway-v3.26.apk from the link at the bottom of that post, and throw the man a Donation - the guy reigns supreme with these devices and deserves every bit of credit for the support he gives us all.
Next, go and find yourself a ROM. AOSP (Android Open Source Project) ones are the best. The origins of AOSP ROMs are Google's original Android source code, so you're getting the base code of the OS exactly as the Original Programmer intended. Samsung (and other OEM's) then get their grubby little hands on that code, then go to town making it control their hardware in the manner they want.
Now, there's two lists of Custom ROMs for the i9505 that are shared here on XDA:
For tweaked and altered versions of original stock AOSP ROMs, visit the Galaxy S4 i9505 Android Development section.
For custom ROMs that are pretty much 'outside the box', and built from scratch by individual developers or groups using Android source code, visit the Galaxy S 4 i9505 Original Android Development section.
No matter what you decide to 'flash' in, if you have questions about the ROM itself, how to flash it, or anything else about that particular release, ask them of the ROM Chef in the thread where you got it from. They're the ones who cooked it, so they've already gone through the trials and errors and successes of getting their ROM working on an i9505, making them the best guys and gals to ask if you have dramas with the ROM. 99.9% of the time the ROM Chef's thread will have in the first couple of posts Instructions on How To Flash, FAQ's, known issues, etc.
The advice I give everyone regardless of what device you have is, Back the damn thing up first - it's called a nandroid backup, Google it - and make sure you clean all traces of the old firmware out of your phone thoroughly. More often than not, the dramas people have when they get up and running on a newly flashed ROM (or, issues in restarting the device after a flash) can be directly attributed to remnants of the old ROM interfering with the new. This is especially so for flashing via Recovery. If you use Odin to flash a Stock firmware, it pretty much smashes its way over the top of whatever you've got installed, and gives you a fresh palate to work with.
Now, if you're having issues with carrier network connectivity, call quality, mobile internet etc., it could be either your network APN (Access Point Name) settings or your ROM's 'modem' package. APN settings are within the phone's Network setup menu. The best list of Australian carrier APN's I've found is at Ausdroid Forums. Modems are a sort of 'try them until you get one you're happy with' kind of thing, and if you're still in the dark, go and read Formhault's post about the subject at...
http://forum.xda-developers.com/showpost.php?p=50787570&postcount=2549
My advice when it comes to modems is, grab a couple of CWM-flashable modems and take at least two days of testing each until you get one that gives you enwhitenment.
Hope that gets your device running smikko, and if you're that stuck you need a bit of special attention, PM me. Lastly, make sure to click on the Thanks button if you got help from this tutorial...

LG V20 (H91010l) AT&T to Stock LG ROM

Hi all! Newbie here.
This has been asked before but I need to confirm a few things.
So I just bought a used LG V20 here in the Middle East but only later realized that it is an AT&T unlocked device. I have attached a screenshot of my device software info. It has all the bloatware and is running Nougat December 2016 patch.
I read that AT&T OTA updates can only be received if it the device has the AT&T sim connected to servers in the USA. I want my device to run the original stock ROM by LG and not a carrier one as such.
I searched around and came across this thread which seems to be the closest situation as mine;
https://forum.xda-developers.com/v20/help/remove-att-rom-to-att-stock-rom-t3809173
Considering that I'm not a techie but I can run things with guidelines and the software version on my device is H91010l;
Question 1) Can I just follow the method Brian has mentioned in the thread or is there anything extra that needs to be done? I've read that some devices are blocked to have different firmwares loaded onto them.
Question 2) What kind of backup needs to be taken? I don't have any data on this phone yet so I have nothing to lose but I don't know how to take backups of system files if that's required. A guide on that would be helpful!
Apologies for the long post and repeated questions, but software help here in the Middle East is limited so I don't want to put myself into any trouble with a bricked phone.
Thanks in advance!

Just follow Brian's instructions. You don't have to root if that's what you would like to know.
Just an #FYI, before some "Senior" member gets on your case, you may want to use the search option in the LG V20 forum, as well as the search option within the threads.
Use keywords, such as "H910 to us996 no root." If you use Google search, you can use something like, "H910 to us996 xda." You're going to have to read a lot, compare information on threads, look up videos on YouTube, but know that if language seems to be a barrier, you can ask. And don't be intimidated with some jerks on here. There are plenty of experienced and knowledgeable folks on this forum...but you also have to do your part in research and troubleshooting.

Verizon Galaxy S7 Edge: Removing bloatware after 1-Clk-Root

Just picked up a carrier unlocked Verizon Galaxy S7 Edge model SM-G935V.
Now that I finally have a model which seems like it should be relatively easy to root, I would prefer to learn to do it using a PC ie flashing ROM, but I have no PC*access*right now.
My main question is:
After rooting my phone using a 1-click root method, will it be relatively easy for me to un-install ALL bloatware & eventually end up with a phone that's running just as efficiently as it would if I had picked out and flashed a good stripped down ROM using a PC instead of some 1-click method?
I'm also considering purchase and use of Super-sume Pro (if the job is done with Kingroot).
Any advice AT ALL regarding what I hope to do would be greatly appreciated... and jic it helps here s a little of my background:
I have NO successful experiences using TWRP or the like w other phones.. although I believe I came close!!... my last few phone picks turned out to be models which were pretty much impossible to root (locked bootloader was the common culprit best I could understand).... Otherwise I think I'd have been able to do at least 1 previous model the flash-rom way.
I DO have A lot of general experience w PCs and have successfully rooted a few phones using 1 click Android software such as Kingroot, but at that time I did not fully understand or hope to remove bloatware to cool battery or otherwise dial in best performance.
It's been at least 3 years since I last performed a 1 click root on any phone.
Thanks in advance for any advice or assistance... I really appreciate everyone & everything at XDA.

Best advice, get/borrow a laptop and follow the instructions in this thread https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616 to see about rooting your S7e. All those "1-click" options never worked for me. With the method in the above link, I can root my S7e in under 15min.
1) First and foremost, what is the current software version your S7e is running? example= G935VVRS4CRI1. IF the 5th digit from the RIGHT is the letter "B" stop! You can't root. If it is the letter "A," or a number, you are good to go.
2) even with root, there is no flashing of ANY custom ROM's. Yes, you can debloat and make some changes, but with the godd**mn locked bootloader the options are limited. Rooting does not unlock the bootloader, therefore there is no TWRP, Magisk, etc.
Others with experience regarding those 1-click methods may chime in with their advice/experience. But none of those instant methods ever worked for me.
Good luck.

Skyline,
Thank you for taking the time. Much appreciated. Luckily I already found out about the software version issue and I'm looking at the number 4, so that potential roadblock isn't one
Let me try to understand exactly what you said towards the end of your reply, though.
Are you saying that even if I use a PC and avoid any 1 click method that I will not have any option to flash a custom ROM? I could have sworn I saw a thread a few nights ago somewhere here at XDA which required use of a PC, specifically for my phone model and it described the altered OS or ROM as being as simplified as it gets, devoid of all Verizon bloatware. Maybe I am referring to it in correctly when I say custom ROM, I'll look for said post to see what I may be remembering incorrectly.
I have personally had great experience w 1-click methods in the past, @ least 4 different phones (older Samsung, LG).. but I have NEVER tried 1-click w a phone thats truly important... as in important enough to seriously worry about stolen IMEI, keylogger or other malware, etc..
I want a perfectly clean, safe "out of the gates" root on this phone, so I'm willing to wait to make sure it's done the proper/best way on my FIRST attempt.
Looks like the thread is already talking me out of using 1-click (might have known deep down that needed to happen lol).
Anyway thanks again for your advice.
When I finally do get to rooting it, I'll post the details and overall experience info here.

Whatever you do, DO NOT UPDATE to the latest software version.
With root, you can debloat all you want. I have next to nothing running on my phone (goodbye Google "services"). You just can not flash any custom (non-official Samsung) ROM's such as LineageOS, Calvioppe, etc... thanks to that damn locked Crapdragon. Much as I love my S7e, when it dies, it will be my last Samsung for that reason alone.
If you follow the steps outlined in the above linked thread, you should be able to root 1-2-3. I have been rooted since it became available and have had zero issues. It will require a PC/ laptop but it is reliable and verified working.
Good luck with your project.

Thanks again for the warning about no updating... I am WELL aware of this, my friend.
Take a look at this thread... it really looks to me as if this person is talking about flashing a ROM on the S7 Edge, no?
https://forum.xda-developers.com/s7...a-evolution-x-samsung-galaxy-s7-edge-t4058837
That's only 1 of at least 2 or 3 similar threads that I've been having a look at lately...

If you look closely, that is for the Exynos version of the S7e. Verizon uses the Snapdragon (ie. Crapdragon) processor which has a locked bootloader for US models.

Ok I get it completely... one last teeny tiny bit of hope- I purchased mine Unlocked by manufacturer. Could that possibly extend beyond carrier unlock and (maybe maybe please just possibly) mean my bootloader is unlocked?
Went out of my way to make sure it was unlocked by MANUFACTURER, not SELLER for obvious reasons. Had no knowledge about chipset... dammit there's always something to miss no matter how much prep one tries to do!

Unlocked just means that the phone is able to be activated on any carrier ie. not specifically locked to only Verizon.
Only the Exynos and Chinese Snapdragon can be bootloader unlocked. As mentioned, I love my S7e, and will use it until it dies, but I seriously doubt I will get another Snapdragon Samsung that is locked down tighter than Ft. Knox.
Good luck...
