[Q] G925I - os 5.0.2 how to know if firmware downgradable - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hi All,
How to know if firmware can be downgraded or not. For example if am on firmware/Baseband G925IDVU1BOE3; is there a way to know if it can be downgradable to "G925IDVU1AOD1" or "G925IDVU1AOE2" before hand.
FYI: I downgraded from G925IDVU1BOE3 to G925IDVU1AOE2 only after doing it practically via odin. So the question is: Is there a way to know if we can downgrade firmware without doing it practically. I asked this question in other post and people are not much aware of it. So thought of starting a new thread.
Also how to know that we can't downgrade from 5.1.1 to 5.0.2?
Thanks ,
Richa

Hi,
The downgrade patch/exploit is fixed in 5.1.1 and there is no way to downgrade it. (As I read in few posts including Ping Pong root OP). If u are in 5.0.2 then u can downgrade to any firmware within 5.0.2.

Hi, sorry for my bad english, I'm from Mexico
Yes, you can do it (I made myself with the 23.1.A.0.726 Lollipop, the HK and US) and is working really fine
Just 2 thing in mind:
1.- You need root and working recovery (in your last rom, for example 4.4.4)
2.- The correct files to make the preroot: the supersu, the ftf and the dual recovery(this works with lollipop http://forum.xda-developers.com/showthread.php?t=2261606)

How to downgrade from Android 6.0.1 to 5.1.1

Hello
I flashed the latest firmware available for my S6 edge (SM-G925F) : G925FXXU3DPDP (XEF).
I've never used Android 5.1.1 on my phone and I asks to you if downgrade is possible at this point (latest BL I think) and if yes, how ?
Thanks you for your further replies
Bye.
I Think Once u Flashed The latest Firmware U can't Go back
Because Of bootloader
Bt U can try Download Android LP And boot loader And put Ur phone in Download Mode Flash with odin
i updated on 6.02...
didn´t like it...
flashed back to 5.1.1 stock without problems (odin)
Hello poci,
You were running with which firmware ?
It's easy to go back to lollipop?
I'm reading some comments off people wich say No, ando some less who say Yes.
i made an OTA update from 5.1.1 to 6.0.2... but i didn´t like the battery drain on 6.0.2......(or 6.0.1 i don´t know anymore)
after clean install of 6.0.2....there was no change at all...
then i went back to 5.1.1 by flashing a stock 5.1.1. firmware with odin...no trouble or anything else...
If flash fails, is my device will be hardbricked ???
if you have the right firmware...i would say "no"
so why should it fail?
i used this firmware for my o2 edge
G925FXXU3QOLD_G925FTEF3QOL1_G925FXXU3QOJB_HOME.tar
Beceause newest bootloaders blocks downgrade, you was in which firmware on Marshmallow ?
don´t know exactly...60.1 then
when 6.0.2 blocks downgrade...

Downgrade to 5.1.1 Lollipop

Good morning,
I tried to downgrade to Android Lollipop from Marshmallow running Baseband DPL3 and Build DQA7. I used the normal firmware, but also the 4 part one, both did not bring any success.
Do you know if the downgrade is possible with my software version?
Thanks a lot!

how you downgraded is your fingerprint sensor working if everything is ok then tell me which firmware you used????
I'm sorry the fingerprint scanner doesnt work. I used an Engineering Bootloader and flashed the S6 edge 5.1.1 firmware right after that without modem, cm and sboot.bin... fingerprint scanner is a part of cm.bin. I couldnt downgrade that so it's avaiable but not working

Sorry bit don't think it can be done as the bootloader has been updated. If you flash a marshmallow firmware you will very likely get sboot.bin fail

Downgrading firmware

I have a galaxy tab A sm-t380 and I'm trying to downgrade the firmware from 7.1.1 to 6.0. I looked online and the only firmware I could find was the latest firmware or the second to oldest firmware. Does anyone here know where I can get older firmware for this particular tablet? Any help is much appreciated.

The tablet came out in 2017 so this tablet is too new for offcail 6.0 and this device has no custom roms so I can't help you.
