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.

Thank you VERY MUCH. Thanks....
Don't use those links, some are redirecting me to questionable sites. Not sure if it does to you also.
I don't have time atm but someone will get you the correct info. :good:
It may have been a bad download that updated you--
Also, those files are too old for you if you look at thread date--

Assume you are now on NC1
Believe you will need to Odin back to NB1 then update to NC1
If you want to root other steps involved--This thread covers it pretty well
Some one else more familiar can be exact, as I am on old bootloader and no handson exp--
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.

The google play ROM I would not mind, but I cant seem to find a way to root my SG4 NC1 firmware.
Do you happen to have a link or directions, please?

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.
Hi, bought this phone yesterday, and flashed the rom of the dev adition, and lost my radio, was lucky enough to get best buy to take it back. I got another one though, and I was wondering if there is an official marshmallow downloadible rom for this phone. Don't just want to flash the ota, want to get the entire rom, and I am bootloader unlocked. Also, is there a cfautoroot for this phone on marshmallow.
Thanks in advance

I just want to be on the latest rom, be rooted, and have a custome recovery. Can this be done with cfautoroot on the xt1575, because beeing blind I have to do everything through fastboot as much as possible because my wife will help me some times but usually she gets very frustrated when she has to work twrp and install things for me, so sorry for the ramble, but that's why I some times ask questions that have already been asked.

Fastboot flash twrp and download the newest rooted w security update and flash, what I did was flash the non rooted to get everything, then flashed rooted to get root. I can understand that there is a lot of clutter. Wish I could do it for you I deff would
so no problem, what wipe should I do before the flash of the rom, cache, dalvik, and data? Also, does the rooted deodexed use a different baseband or modem, and is there any advantage to deodexing in this day and time, I heard that most of these roms these days were actually not odexed anyway, just asking and learning
Do not do not use fastboot to wipe anything. Download the regular from the link above and the rooted and put on SD card. Flash recovery in fastboot use bootloader to get into recovery(otherwise phone will overwrite) wipe everything accept external in recovery and flash the ROM with February security patch
https://www.androidfilehost.com/fid=24459283995299100
Then after it flashes completely flash https://www.androidfilehost.com/fid=24459283995302251
Then let reboot. I did this with no issues.
Requesting guidance before I brick my phone.
I currently have bootloader unlocked, twrp installed, and my nexus 6p rooted. I'm running 7.1.2. I've also changed a line in the (build.prop) provisions in order to tether free (since I am on at&t)
Basically, I'm wanting to install pure nexus. I have the custom rom file and the vendor image file.
Before I install from, I'm wondering if I need to unroot first? Also curious if how "shamu" will affect things since I'm on Angler.
Thanks!
Okay you need to stop everything you're doing and read this topic until you know what is what.
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page577
First of all, you obviously wouldn't flash a Shamu package on Angler. That's a great way to brick your phone, permanently.
Read every single step in that guide above, even if you don't think it's pertinent to what you're trying to do. Read it a second, third, fourth, fifth time until you know the steps by heart. Until you know what's next.
Also, download the correct Angler zip file and DO NOT FLASH A SHAMU ZIP ON YOUR PHONE.

You can follow the original advice I posted above. Read that thread I linked. It's ALL covered there. No sense in me writing everything up here when all you need to do is click the link I posted and follow the return to stock sections. There's even one for maintaining your data. Read the thread. It covers literally everything.

Sorry I don't mean to bug man but I'm so lost. I'm trying to find what you are referring me to but I'm not finding the info I need I haven't been on here too often so this is like a pain in my rear so far. Plus I'm a very hands on kinda learner so I need some like handicapped help lol If you don't mind I don't want to pester anyone...
I was able to load pure Nexus. I didn't realize there was a pure nexus rom with Angler on it.
My main question was if I had to reverse the root. But I'm good to good now.
Rom loaded, vendor image loaded, and Google Apps loaded.
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.

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

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?
I'll put the long story below..but spare those that don't want to read. The short is, I'm not able to ADB Sideload the OTA images as it always fails to verifiy signature at about 40-47%. I've searched many places and not found a fix. So I'm hoping the genuises here at XDA which I frequent can help.
The long story. I've flashed roms for many years. My current device was the Nexus 6p. Running XE Rom I think it was. Flashed an update all was well, but my sim card would not show up. I was on MetroPCS and remembered needing a different radio. Flashed that,still no sim. Decided I'd go back to Stock since those had been updated to 8 by now. Flashed the OTA and followed some steps by another thread on XDA, one of the last was locking the bootloader. I had not booted up so I didn't know if my system was working. My big mistake! I locked my bootloader and don't have a system to boot into so I can enable OEM Unlocking. So now I only have adb sideload, can't flash individual images through fastboot! I think it can be recovered but for some reason the signature verification issue keeps coming up no matter what cable or PC I use.
If anyone has any thoughts I'd love to hear them. I have since moved to a Hauwei Mate SE and am pretty pleased but will not be a flashing phone I don't think. I loved my 6p and it still had lot's of life for me. I hate to sell it for parts at this point.... Thanks for anyone willing to chime in.

First, if i understand right you tried to flash OTA over custom rom to return to stock?? To go to stock you must flash full system image, not OTA.
And second, why the hell did you lock the bootloader??...you dont lock the BL unless you are 100% stock..
I know i didnt help you much, but if your BL is locked, dont know how to help...maybe someone else know how to unlock it again
Meanwhile read this guide,it will help you to understand some things:

Oh believe me my head hit the wall for sure! I got careless and wasn't thinking straight. No reason to lock the boot loader except it was on a list of steps to get back to stock..and I guess it was late! doh.
There are lot's of posts/videos I've seen that should allow what I'm trying to do with sideload adb but mine keeps getting a signature verification error. Each new full version of a release 7.0 8.0 etc..has the entire rom, images etc. So your suppose to be able to flash those even though they are OTA updates... *shrug*
It's a blur what I did exactly in some areas. I at one point may have tried to flash the set of Stock IMG files as well. But for sure now all I'm left with is a locked phone with who knows what on it! Stock recovery...some form of 7.0.0 that has NYC as letters...that I can find NOWHERE! on any official releases...
Prob trash, I really want that night back..lol.
