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.

Is There an Option to restore imei

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

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.
I need help to unbrick my phone. Here are the details of my phone and things I did before it became useless.
- Version: Updated version of Samsung Galaxy S6 Edge Marshmallow Android 6.0.
- replaced its recovery with TWRP via odin (3.10.6)
- install a ROM with the use of TWRP recovery.
- After rooting my phone and flashing a new rom via TWRP, I can't use my phone's physical buttons.
I also tried full-wipe installation of Custom rom and I got the same issue. I tried restoring it to a stock rom, but it always says "Fail".
Do you guys have any suggestions how can I fix my phone?
Which rom did you flash?
What point in odin does it fail?
I take it you have G925F? Not G8.
Whats your region and what firmware did you try to flash (stock)

Thank you for your reply. Here are my answers:
-I flashed "CarHDRom" to my phone using TWRP 3.0.
- Yes, 825F is just a typo, G925F is the correct model name. I double checked it in the box.
- Philippines, and I already downloaded the firmware that you suggested in another post about softbricked g925F (G925FXXU3DPAD_G925FOXA3DPAD_XEU).

Make sure you have origional cable and debug mode is on in dev options.
If this fails look for the firmware in the picture. Download and flash that.

I suggest TWRP. Make a full Nandroid back up before just incase. But if anything goes wrong you can just flash that stock back to fix.
I would root first with cf autoroot.
Then flash your ROM.
Do a full wife when rom installer asks as this is safest way.
If it bootloops just wait.
Glad i can help
Well it looks like CarHDRom is not compatible with my phone. Tried flashing it twice and I waited for 30mins of booting but it doesn't continue.

It is compatible im using it mate. Did you do a clean install? Wipe data when installer asks? My first boot took around 30 mims
30mins? Seriously?? Yeps.. I did a full wipe before booting with the CarHDRom.. is it the most stable TW based ROM now? ? thanks !

I got a customer who wants to downgrade from Android 10 to 8. I know Samsung has anti-downgrade protection and you can't flash older firmware using Odin.
What about rooting the phone first though and flashing the Android 8 firmware using TWRP? Wouldn't that work?

You'd have to flash system, vendor and a kernel that can run Android 8. Just flashing the firmware straight up won't work

I guess we both having same issue. I upgraded to UAETG3 and the mobile signals were gone. IMEI status is 'NG' and it says emergency calls only. The binary of aforesaid update is higher and it won't let me downgrade. Have you found a solution?

Try to flash complete firmware from odin and if not then your efs is corrupted !
I think combination file might downgrade with re partition
Any information how to downgrade modem and bootloader?
