I rooted my Galaxy Note 2 and used an app from the app market for backing up the EFS, the app crashed in the middle and I ended up losing the EFS. Nothing worked and I had to take it to the service centre (thankfully I could remove the flash counter and make the status to official so they did it within warranty.)
I have exchanged the phone with my sibling, I have the s3 now. The battery life on the official UK 4.3 version (since it wasn't out for India yet) sucks(any. I would like to try custom Roms.
Kindly link me to any existing thread(I Couldn't find one) if its there.
What all precautions should I take?
1)Backup the stock ROM(using Titanium Backup?)
2)Backup EFS(using?)
Thanks in advance

you can use the hc-KTool to backup the efs, is easy to use and free downloads from the play store. backup the stock rom is a custom recovery such as CWM, Philz, TWRP.

another precaution may be, install the correct kernel for rom you wear. clear that if you change custom kernel. but just these two precautions, especially with having the efs backup.

but EFS backup would require root? And the root method available is for 4.1.2
Rooting and Custom Roms were so much more fun on the sk17i

Just flash latest official firmware from Samsung and then u will be able to update ur device!!! Use Odin to flash!!!
Hello,
I bought my SGS3 more than a year ago. It came with 4.0.4 (ICS), I inmediately changed the ROM to have a pure Samsung one (I live in Mexico, so I wanted to get rid of the TELCEL ROM). After some months I changed the ROM to Jelly 4.1.2 and I kept the phone with it.
I always have rooted my phone without any issues, in order to be able to make backups with "titanium backup" app, so everytime I change the ROM....I do first a backup and then I flashed, so I have to be able to root the phone in the next ROM.
I read about the 4.3 release in October 2012, but after a week I read that too many issues were going on.....so I decided to wait.
So finally, I saw XXUGMK6 from "samsung-updates.com" page and I downloaded it.
I researched a little bit about the official ROM and the version XXUGMK7 was released then, so I decided to change it with this version.
Once I flashed the phone with this ROM everything looked fine, so I proceed to "root" it using ChainFire procedure (CF-Auto-root), but I have not been able to do it!!
I already read a lot of threads looking for solutions, I followed the indications..........but it is not rooted.
I got the right Odin Version, the right ZIP for rooting (CF-Auto-Root-m0-m0xx-gti9300.zip)........followed the OP by ChainFire.....but it does not work.
So.....I humbly ask for help, I really do not want to go back on 4.1.2 because not been succesfull in rooting.
Regards,
Guile

If you got the I9300 model with no sim lock- no problem.
Ps- notice that if your current build is below EMG4, than your file partition will be changed to EFSv2,
needs to be noticed if you'll try to go back to 4.1.2 afterwards

I think he can go back after flashing 4.3 ROM. I have done that.
Aashish, you can install any ROM as per your requirement if SIM is not locked with any SP.
But there is a chances of loosing IMEI. So please take backup. Search and download MG4 modem handy.

Yeah what you propose seems very straightforward BUT it would be advisable to do a full backup INCLUDING EFS, just check the EFS box in TWRP for instance, as it's not usually included in a backup by default.

Ah I get it now, in which case I would be tempted to go to an Indian 4.1.2 firmware through ODIN and the update through OTA if that's possible. That would reduce the chase of stuffing up your EFS by using an official Samsung update procedure.
Hey Guys.
Once i tried to downgrade my Galaxy S6 Edge SM-G925F from Marshmallow to Lollipop with odin, but it failed and i had a brick. I tried different Versions of Odin and with much luck i fixed my Phone. But now i am insecure and hope to get help from you. I installed latest Smart Switch Version. What do i have to do to downgrade without bricking my Device?

Only possible when flashing 5.1.1 custom rom via recovery, but you will lose your imei, BUT you can backup your imei and after flashing new rom restore it.

Yes before you proceed you will need to install a "custom recovery" (Search about it if you dont know what it is)
Go to recovery like you want to format but instead go to "Backup & Restore" and select backup and then select "efs" which is IMEI.
After flashing a custom rom and after the first boot you will notice that there is no signal, so go to recovery and select to restore efs.
I recommend you to backup efs to ext sd card.
This will void your warranty, even downgrading it self will void it.
Goodluck!

Any firmware 4DPG1 or above can not be downgraded. Im guessing before you was on U3DPAD or lower which can be downgraded. The first MM builds could be downgraded. But any 4xxxx can not
ah ok....
then i downgraded fast enough
my main reason of downgrade:
in MM it is not possible to change the font with HiFont App....!!!
i see other people saying that it's possible.
but i have one of the latest builds so, in your opinion , it is impossible for me to downgrade.
but are you sure? i can't believe that, i want absolutely a solution, i am searching it from so many time, please help

What build number are you in? It is impossible to downgrade from a late build 4xxxx. I have tried absolutely everything. The only way is to flash a nandroid backup but even then you will lose imei. You can always back up efs and restore but its not always as straight forward to restore it. You would also need to flash a new bootloader and modem.
Did you make a nandroid backup of your previous firmware? If not then you cant try that.
The only other way you can try is to flash a 5.1.1 custom rom. Again you will lose imei. So efs backup is important. You would also need to flash BL and modem again.
There are roms based on lollipop which is a much safer way to revert back, try one of them.
Overall i wouldnt try it bit its up to you. If you do and you find a way to do it let me know.

You cant downgrade after 4xxxx firmware mate. After updated bootloader your stuck on mm.
There are ROMs based on 5.1.1. But because you flashed 4xxxx firmware you cant downgrade. All lollipop firmwares are 3xxxx
