Downgrade to 5.1.1 Lollipop - Galaxy S6 Edge Q&A, Help & Troubleshooting

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

[Q] G925I - os 5.0.2 how to know if firmware downgradable

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.

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...

Honor 5X - KIW-L23 Marshmallow and bugfix update

Im having Honor 5X KIW-L23 model. I didn get EMUI 4 update or any bug fix update.\
The firmware for KIW-L23 has also not released.
Is there anyway to overcome this by using another OS? Will other OS suits to L23 ?

There's a way, but it's too risky, I don't recommend it.
I also have this model and I am seeking the stock firmware for it. I installed a custom ROM and forgot to take a backup (stupid). Now I can't go back to stock because I can't find any stock firmware online. What options do I have to get back to stock? (I miss my fingerprint reader)
Is there a KII-L23_Android 6.0.1 update?
I need a stock ROM for this model too.

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

How to go back from EMUI 8.0 rooted to 5.1 stock?

Hi everyone! I have rooted and unlocked my H9 STF-L09, i find it ok i guess, but i really miss the EMUI 5.1 days... I just think that was better.
So i'm asking you, is there a way to go fully back to stock Nougat, maybe with locked bootloader?
Thank you for your attention.
If you are rooted, your bootloader's actually unlocked.
So, because you're on oreo, you could use HuRUpdater to downgrade to a nougat firmware.
I'll test C432B184 rollback packages, if C432 is your actual region, as this version is the latest nougat build released for honor9 :
Code:
