Reverting back to Stock Rom From Andriod 7.1.2 - Galaxy Note II Q&A, Help & Troubleshooting

I want to revert back to Stock ROM on my Galaxy Note II N7100. Currently I am on CrDroid 7.1.2. I am afraid that I will lose my IMEI if I downgrade. Can anyone kindly explain the process to downgrade or at least let me know whether the downgrade is possible or not?

Download mode and Odin are necessary.

Yes, you can flash back to a stock ROM and your IMEI should be intact.
You will need Odin and the latest stock ROM from updato.com, sammobile.com, or samsung-firmare.org.

[Q] Back to stock (KitKat)

Hi guys, hoping to get the Galaxy S5 tomorrow. So I wanna sell my Note 2.
I need to go back to stock to do this (not rooted, stock firmware)
I am currently running a 4.4 stock based custom ROM
I know with some Samsung's you can't downgrade after getting 4.4 firmware installed on your device.
Or can I download 4.3 firmware from sammobile and flash through odin without issues?
If this is the case. Would someone please Tell me a link to a 4.4 stock firmware I can flash through Odin please? Can't seem to find one.
PLUS any recommendations to prevent bricking my phone will be greatly appreciated!

Yes you can downgrade after a 'Custom' 4.4.2 to 4.3, not sure about official because it is still not available. Try flashing it with Mobile Odin Pro instead of PC Odin.
Note: Backup your all content and EFS as well to save signs of your phone.

[Q] Samsung SGH I747 - Restock Original OS

Hello,
I have installed CyanogenMOD on my Samsung S3 (SGH- I747(AT&T)... Before installing CMOD i had Android 4.3...
Sinc 4.3 had lot of issues, i decided to root my device and installed CMOD....
Now I want to restock to my original ROM(AT&T I747 UCUEMJB Stock Restore).. How should I do it... Please help..
Is it advisable to download the original ROM from "samsung-updates.com" and simply flash it using ODIN..
Please advise
Do you have the 4.3 or newer bootloader on your phone? If you do, do not flash any ROMs that try to downgrade your bootloader. Attempts to downgrade from your current bootloader could brick the phone.
This might help if you're on a stock 4.3 bootloader: This might help: http://forum.xda-developers.com/showthread.php?t=2722660
If you have the 4.1.1 or 4.1.2 bootloader, you can flash a stock ROM via Odin and OTA to 4.3.

How to switch ROM? From Lollipop back to stock, help!

I am running stock right now (JB 4.2.2) and I am planning to flash a Lollipop ROM (AICP 10). If I create a backup (for my stock ROM) at TWRP and did the needed measures to flash the Lollipop ROM and was successful however I want to return to stock ROM. Do I just have to factory reset and restore my stock ROM backup to have a stock ROM again? Sorry for this noob question.
Heeeeelp!
Any idea if that would work?
Just use odin to flash any stock rom
So backup-ing in TWRP before I flash Lollipop from my current rom [Stock JB 4.2.2] is useless?
You can also use your backup from TWRP.
But It will then show that it has been modified, could be a problem with the warranty.
If you want to go back completely for warranty then odin is the way to go
Thank you! I actually don't care about warranty since mine is overdue already. All I wanted to know was if I will be able to go back to JB 4.2.2 with that backup in case I have problems with Lollipop.

Return to Stock From CM12.1

I'm currently running CM12.1 on my phone. I love it, but I want to return to stock and give my phone an "out of the box" feel, and return it to the way Samsung made it to be.
I follow the typical instructions found here, but I always get an error (no screenshot available. Sorry!). I'm running Windows 10 and I have the proper drivers installed. Is there something I'm missing?
If the phone is running a 4.3 or newer bootloader, you cannot flash back to stock using a stock rom from sammobile.
Before flashing anything, I recommend verifying the bootloader and modem before flashing anything else. An improper bootloader and modem combination could brick the phone.

Alright. Thanks. A bit disappointed, but thanks anyway. Besides, CyanogenMod isn't bad.
I was just running CM 12.1 / 13 and I was able to revert back to Roger's Stock ROM Android 4.4.2
Try Odin3 and installing the stock rom. But you should always verify the bootloader.

If the OP is running the i747, it is the the AT&T version of the s3. AT&T never released a full firmware release for use in Odin after 4.1.1. AT&T only released OTA updates that upgraded the phones from 4.1.1 to 4.4.2. In order to flash a stock AT&T 4.4.2 ROM, it needs to be done from TWRP.

Hangs on setup

hey can anyone help me? i've recently reverted my note 2 back to stock via odin and everything seemed fine. When the phone booted and i went through the setup process it always hangs. No matter what i do it always hangs. I've tried reflashing it and rebooting it over and over again but it always hangs. anyone know why this keeps happening?
Are you flashing the latest stock ROM? You're performing a factory reset before booting the ROM for the first time?

Yup latest stock rom, and before i flashed via odin i deleted my previous rom via twrp and formatted internal storage so its 100% clean
I've downgraded a Note 2 sgh-i317m to 4.1.1 from 4.4.2 by flashing a stock 4.1.1 ROM from sammobile.com in order to network unlock the phone. Flashing the stock 4.1.1 ROM tripped knox and could be installed via Odin because the 4.1.1 ROM from sammobile.com did not contain a 4.1.1 bootloader so I wound up with a stock 4.1.1 ROM on a 4.4.2 bootloader. After unlocking, I flashed the stock 4.4.2 ROM again and the the phone worked as it should.
I'm not sure which phone you have and I'm not sure downgrading and upgrading will work in your case but it's something you may want to look into.

I've managed to get the phone working (N7100) and it seems to run fine on Nougat. I did some testing and indeed it would always crash on setup with kitkat roms. I wonder why this is the case....
It is strange that kit kat causes a problem.
Have you tried using a different version of twrp to wipe the system before flashing with Odin? Can't think of anything else that may solve the problem.
