Yes, its possible to rollback to previous version. Download the previous version of Stock ROM from sammobile and flash this ROM via Odin v3.07 then it will roll back to the previous version..
Hit thanks if my post is helpful.

No way to rollback into previous version, as no vendor supports downgrading . If u need your old software, just download Original stock firmware (definitely some older version :silly and reflash it with Odin as @Parth2187 mentioned:cyclops:

This is what I did. I had a nand bqckup of my 4.1.2 stock rooted rom.
1. Flashed 4.1.2 stock via Odin.
2. Root3d and flashed CWM recovery.
3. Once in recovery rolled back my original nand.
Please note if u end up in a boot loop. Make aure u go to stock recovery and do data/factory reset and wipe cache and u r good to go.
Hope helps. Worked foe me.

If you root your phone, you won't be able to receive OTA updates and it will void your warranty. If you unroot you can get the OTA updates.
To root see this thread
If you want to unroot, see this thread.

Try doing factory reset thats best thing possible u can do

I don't think a factory reset can unroot a device. I am not pretty sure about this, if u are successful in that, its okay. But factory reset just formats the internal SD card. It wont do anything with /Root directory. When you are rooting a phone, we flash SU to the /root directory.. Then how come a factory reset can unroot a device. Probably impossible! Correct me if i am wrong

+1...factory reset does not unroot...........flashing stock rom through odin and using traingle away ( not in that order ) would unroot the device..we are priviledged that our device has all prequisites for rooting and unrooting...

I tried flashing the old rom with odin but it gives some error :/ maybe my firmware has sm problem :|

If you have flashed the 412 stock rom that will install a bootloader older than dmg l1 which is why you lose imei. The bootloader patch is essentially.just the dmg1 bootloader and your efs has been changed sonthat only dmg1 or newer can read it so if you have a efs backup you can restore that or simply flash the blpatch tonreplace the old bl with dmg1 which should fix.your problem. Shouldnt effect the binary counter as far as I know but if it does you can always triangle away again

Root66 firmware is in my thread in development section, link in my sig. Youll find instructions for Odin there and all over the place with a quick search and from the sticky threads. Not being rude, just don't like redoing what's already out there. If you have any specific questions about the process, ill be happy to answer them.

Flashing any recovery or kernel trips the warranty bit. No way around that and no way to reset it I'm sorry to say. Since you've flashed recovery its likely tripped already so flashing kernels and roms won't make any difference anymore. The binary counter doesn't matter as its easily reset. But if you have a custom kernel or recovery it'll retrip to 1 every time you boot.

You can flash Any of these roms via Custom Recovery TWRP and you will do fine.
Do note, some people have mentioned that with a 4.2.x or 4.1.x Roms, sometimes their IMEI goes missing. So take a Nandroid and EFS Backup before hand.

Perseus mentioned the nv (efs) backup before. Easiest way to protect yourself is open a terminal emulator and enter this.
su
reboot nvbackup
Device will reboot and create an internal, hidden backup of your nv data. I highly suggest doing this.

If you mean you made a nandroid backup, that is completely different and does not include any of the NV data. The backup I mentioned is intended to protect you from ever losing your imei in the first place.

http://forum.xda-developers.com/galaxy-s3/general/galaxy-s-iii-partition-layout-basic-efs-t1689623
I used this method.

Ok , first, never use anything you find in the international models forum for any US model. They are very, very different devices. If you made an image from mmcblk0p3 as stated in that thread, you actually made a copy of sbl2 I'm pretty sure.
Also, the imei, (the important thing here) is not actually stored on the efs partition as it is in some other devices.
Run the command I posted before for the best solution. If NV corruption is ever detected, it should auto restore from this backup during boot up.
And again, stay away from the international forums. Most of the info there will not apply to our devices here and many, many people have bricked due to that mistake.
And delete the backup you made. If you were to try and restore it to your device after updating it at some point, it would most likely cause a brick.

OK thanks I'll get on that . I flashed a remix ROM and everything seems good right now. I'll try to back it up today.

Read up on Kit Kat, you might not want to upgrade. You will lose write access to the SDCard. There are ways to then fix it, but you could lose function in some of your apps. Samsung finally adopted the Android specs for write access.

I deleted stock apps, help! :(

Hello I tried rooting my device using Kingo Root, well it was rooted successfully. Now, I messed up in deleting some bloatware apps from a list I saw before making a backup . Then when I click the settings>about device, it crashes. Then when I try to factory reset, the apps I uninstalled didn't came back. Please let me know what to do, I just want to make the phone the way I got it then root it.
ps: I googled and some say flash the stock room, I'm scared to flash it because I don't know the firmware version of my phone since I can't access the About device of my phone. I'm in the Philippines btw.
pps: I don't know if it might help but, I installed Kies and the fimware was the latest and it was: PDA:NC2 / PHONE:NA3 / CSC:NC2 (AFR); I don't know how to read that, no google result so far. I'm planning to download firmware from this site: //samsung-updates.com/device/?id=GT-I9082

You can use Partition Backup app. Nandroid backup will backup most of the main partition, but i prefer third party app which will show some unseen partition.
As for the memory thing, i believe @Yousef Mohamed have better knowledge, he even made a flashable zip for expanding the internal memory size.

Gonna try it out thanks. I'm going to do what I learned from here to my future devices Yeah, I hope Yousef does reply.

EFS is most important "recoverable" partition
Bootloader partitions are the most important because without them you can't even boot the phone ( you can't boot to download mode , recovery mode or even the OS )
So you can't recover it

How can i remove root without using Magisk ?

Hi guys,

I flashed original boot img but OTA still doesn't apply.
The only solution might be to flash stock rom 9.4.0 (July) using MI flash tool but i'm afraid that It isn't possible to do it

Installed org boot with A/B?
Did u modify system partition? Like build.prop OR something?
If nothing works you must try using MI Flash tool with the stock ROM

I would like to keep data

Connect the Phone to the pc via USB in the flash tool must say "refresh" once you click refresh must apear your device with de adb/fastboot id. Then click select, choose the folder you've downloadwd, then click flash. Now wait until the flash tool says "flashed".
After that your Phone must have stock ROM ready for OTA. If you want to keep magisk i'll recomend you to follow BubuXp guide to install magisk with proper support for OTA's

Thank you very much, i will do it tomorrow.
One lady question, i saw that the rom is 9.4 while my device is running 9.6.
Is this a problem ?

There's no problem it will flash everything a leave the device with stock ROM, i recomend you to use the first way, you will lose the data, but I think is better, anyway i think both methods will lock the bootloader, so anyway you will lose the data, make backup and If u need something tell me.
Good luck, LB

There's no problem it will flash everything a leave the device with stock ROM, i recomend you to use the first way, you will lose the data, but I think is better, anyway i think both methods will lock the bootloader, so anyway you will lose the data, make backup and If u need something tell me.
Good luck, LB
