Downgrade Samsung Galaxy s7 G930F (oreo 8.0 to Marshmallow 6.0.1) - Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri

Hi,is there any way to revert my samsung s7 back to the stock version 6.0.1? it currently mounts 8.0. THANK YOU

I would be interested too.

I think it is not possible atleast not with odin because of updated bootloader. You can try with twrp and an 6.0.1 based rom if you find any. But i cannot guarantee everything will function

i tried the rom "the galaxy project" with twrp everything works,but i would like to go back to the original samsung stock,i had read about the bootloader problem,i was hoping someone had found the solution

is there a method? does anyone know a method?

Unfortunately there is no other way do to the bootloader

Mixing firmwares is generally not recommended, but it has worked for me in the past. You can try to downgrade only the parts that aren't version locked.
For that, you will need to extract the tar.md5 and resulting lz4 files to get to the raw images and use heimdall to flash them individually. Good luck!

...thank you

how is it going?

G928A firmware downgrade?

I'd firstly like to state I am new to the forums, and give my thanks to brilliant people who give guys like me somewhere to turn. Now, my question is, is it possible to downgrade from MM PJ1 to OGG or OJ1 or lollipop in general. I've seen a similiar thread about a UAE version or somethung that said it was possible. I have successfully downgraded a Note 3 from lollipop to kitkat, which has locked bootloader too if I'm correct..?, but I would like to have any input before I do this as it is my main phone. Thanks!
yes it is possible.

So in theory, i could downgrade to Lollipop and use the kernal auto-root to possibly get rotot? I just got an HTC 10 so I'm really itching to mess around with that s6 Edge Plus. Lol.

How do I downgrade From 7.0 to 6.0.1??

I need to root me S& active and it does not look like 7.0 will be able to be rooted anytime soon.... so is there anyway I can revert back to 6.0.1 my phone is new and has 7.0 on it (just purchased 2 weeks ago) So I am assuming I need to flash the whole PK2 firmware... does anyone know where a link is to the full download to it?
Edit, heres the mirror to get from 7.0 back to 6.0.1
Confirmed working, and was able to switch from 7.0 back to 6.0.1 then back to 7.0 and then back to 6.0.1
Found this one G891AUCS2API2_CL8737252_QB10881022_REV02_user_low_ship_MULTI_CERT.rar here

Anyone no a better mirror for a stock 6.0.1 firmware flash?
Well found the password for the file....
password: G891AUCS2API2_FULL_FSFD
trying this again.
edit: Correct password above, file now working correctly
edit: Correct password above, file now working correctly
Its 7.0 not 6.0
this isnt 6.0.1
Has anyone found the 6.0.1 firmware for this phone? I can't seem to find it anywhere.
I also really need this firmware as i'm bricked, Every link I can find has failed me. It seems to have either expired or been removed.

Do you know if it will brick if I downgrade the firmware? Its on Nougat and dont want to risk having a paper weight.
I'm currently testing this one. Got S7 Active on 7.0 trying to downgrade to 6.0.1 to root. Link I have posted above was pointing to 6.0.1 firmware. First attempt to downgrade failed so far. S7 Active survived so far.
I'll be testing further after work.

Hi. I'm back. Took me a while, like 3 hours to get this one right, but I have managed to root S7 Active on Android 7.0 by following guide from the Russian site. I'd help if anyone is willing to root on 7.0
i had already put up tutorial, and links for Root on 7 here...
https://forum.xda-developers.com/s7-active/development/rom-mod-release-t3635879
also a nice script to debloat, and add s8 mods too ...
(its also where your QD4 odin file originated, look in the root of the rar file )

Samsung Galaxy S4 mini i9195 NEED flashing tools, rom and some advice

Hi
I have a Samsung Galaxy S4 mini i9195 and i'm curious is it possible to flash a phone without battery over Flash Tool ?
I am using MediaTek SP Flash Tool v.5.1728.00 and i was flashed my other phone Huawei Y360-U61 without battery, but i can't find any stock ROM for gt-i9195.
Any advice will be good.
Thanks in advance.

S4 mini does not have media tek chipset so that tool will not work. You need Odin or Kies (for Widows PC'S).
Edit: you can get a stock ROM from

Have you read this FAQ?

You need odin and corresponing rom. I found newest through search with google. I have an european model and could upload it for you to my gdrive account. Its Android 4.4.4 from Debitel (Unbranded). Alernativly you could install lineage os 14.1 from arco68. Its newest android 7.1.2 updated weekly. Works very well.
https://forum.xda-developers.com/ga.../rom-cyanogenmod-14-0-s4-mini-3g-lte-t3471761
I have seen you are from croatia, so ideally you find a rom thats for croatia. On sammobile you find just 4.4.2. I have a french (reimport) GT-I9195 and after flashing of german (because of releasing roms much earlier in germany) I was able to change but not anymore back to french. Don't know why, but I can live with them. After flashing I have to go to samsung recovery and Iam not sure what I have exactly done. I have since 8 months lineage os. I think it was enough to go to recovery mode and in log you see thats the recovery mode changes some parameters and the phone works again. Before wlan does not worked for me. Alternativly you could try -> Delete cache -> Factory Reset. But Iam sure this was not necessary.

Need to know if I can downgrade Sprint Galaxy S9

Hi,
I have a Sprint Galaxy S9 running One UI Version 1.0, Android 9, Basebase G960USQS4CSC8.
I need to downgrade this phone to Android 8 in order to successfully record audio calls from both parties.
I tried flashing G960USQU3BRK1_G960UOYN3BRK1_SPR & G960USQU3BRJ5_G960UOYN3BRJ5_SPR but they fail.
I need to know if downgrading is at all possible and if so, what file I need to use to successfully boot this S9 into Android 8.0?
Thanks!

You cannot downgrade the bootloader
G960USQS4CSC8 << Version 4
Flash an equal or higher BL version firmware
Thank you for the reply.
So I cant downgrade the S9 I have to Android 8 due to its Baseband version being 4...
Looks like I'll only be able to downgrade/upgrade the firmware using an Android 9 Firmware version, Not Android 8.
That really sucks.
Does anyone know what Android 9 version works with Call Recording applications?
Is this something that will eventually be fixed or this is how it is/deal with it?
Thanks!

Odin is official Samsung software for flashing official Samsung firmware.
But, once you are on the latest Pie bootloader you can't downgrade to latest Oreo, so it will be impossible.
Dude... there are a bunch of J600F Oreo ROMs hellooooo

Galaxy J Series

Just tested for 2 days:laugh:
