Downgrading Galaxy s8 G950U1UESC5CRF5 from 8.0 to 7.0 - Samsung Galaxy S8 Questions and Answers

Hello, I have tried many attempts to downgrade but was unsuccessful. I have spent the past 3 days non stop trying every possible solution that popped up but I still can't solve it. It's for a research job and I desperately need it completed. Some of my device's details are:
Carrier: XAA
Version: 8.0
Baseband version: G950U1UES5CRF5
Kernel version : 4.4.78
Knox 3.0
-Downloaded 7.0 firmware from Sammobile,
-Tried multiple versions of Odin ( from 9 to the latest 13.1)
I get this error message on Odin after abl.elf:
FAIL! (Auth)
Complete(write) operation failed
All threads completed ( succeed 0 / fail 1)
Desperately need help, thank you!

You don't that anti rollback kicking in the only 7.0 is a combination file which is no where near a usable img

Sorry, I don't quite understand what this means? Basically, I just need a version of Android lower then 8 due to an App's requirement

Downgrading is not possible if you need a lower than 8.0 firmware it will have to be a different device...
The 7.0 combination file I spoke of is a samsung test rom which is meant for phone diagnosis
It is not functional as a phones operating system let alone a rom to run apps on....
The error you received is the phones bootloader preventing downgrade there is no work around, hack, trick,or method to do it

Oh I see. That would explain the painful 3 days Ive spent trying to do this. Would you happen to know if this device is able to be rooted?

Almost every other thread above and below this one asks and answers....

N910F 5.1.1 upgrade failed - help please!

Used Odin 3.10 to update my 910F from 5.0 to 5.1
It seemed to go OK but at the end the phone was in boot fail.
When I run it again, Odin fails right at the end and leaves this message on the screen:
UDC START
Volume size is too big 81920 < 471840
ODIN : Invalid ext4 image
I used the German 5.1.1 from Sammobile.
How do I get out of this please?:
You'd better flah this one: http://forum.xda-developers.com/note-4/general/rom-unofficial-repacked-lollipop-t3105093
It helped me.
Thanks for the hint!
I ran that one and Odin finished successfully, which it wouldn't do before. But the phone still won't boot beyond the Samsung stars screen, with the blue light on and getting hot.
After that I tried again with the official 5.1.1 from Germany, and this time Odin went through OK with no errors shown, but the phone still hangs on boot.
Any more ideas?
Finally fixed it.
I stumbled about with a few different firmwares, and eventually got it to a state where the official 5.1.1 finally came to life.
Still not sure exactly what happened, but I now have a Note 4 with 5.1.1 and working again.

Probably you want to downgrade the bootlader. If the firmware is A310FXXU2**** you can't downgrade. If the firmware is A310FXXU3**** you can downgrade. https://www.sammobile.com/firmwares/galaxy-a3-/SM-A310F/SER/download/A310FXXU3BQD2/132023/

You can downgrade a firmware is the firmware has U3 bootloader. For example A310FXXu3CQI2. If the firmware is A310FXXu2**** you can't downgrade.

Hello i have a samsung galaxy s9-g960f with binary 17 i think, odin says device 17 binary 2 (or whatever i want to flash). Is there any way to downgrade it to binary u2?
Samsung's downgrade lock is an insult to users. The blatant destruction of the device is a mockery of the user's intelligence and an abandonment of Samsung's reputation.

Wifi models don't have locked bootloader but LTE models do.
Downgrade firmware to Android 6, you need a version closed to the release of Android 7. It will fail if you're flashing older firmwares.
I have no problem of downgrade from QF1, Android 7 to PL4, Android 6 ( US firmware ).
You can try this one, region doesn't matter.

Download samfirm from here :
https://forum.xda-developers.com/attachment.php?attachmentid=3803841
Enter your model no. example SM-G935F
And region code: INS
And click check for updates, it will check for latest version available for your region. Then proceed to download.
If samfirm gives some error codes, then I guess you have to use updato or sammobile. Here is the link for updato https://updato.com/firmware-archive-select-model?record=C97F8A453DF911E89F15FA163EE8F90B

You know I would have never advised anyone if I haven't tested myself. You can flash without any issues, but nougat will seem much laggy, don't know why. I just experienced it after downgrading that last nougat release for my region was much laggy then it was before I upgraded to oreo. But it may just be my imagination because oreo is more responsive and faster than nougat.
Nope S2 won't hurt. The thing is that the number after alphabet is same i.e 2. S2 is update from U2. 2 must be same. Also firmware is same for both F and FD models.

Yes always enable oem unlock, just in case you may need to flash custom recovery or root, just to be safe its good thing to always keep oem unlock enabled.

!!!!WARNING!!!!!! TOO LONG!!
Thank you for your help but this post did not work for me. After downgrading and trying many times to get imei i flashed the FACTORY BINARY but nothing i had lost modem and did not have baseband and NVDATA.
so with my heart rate @ a billion beats/sec with thoughts of i had bricked my phone. i clam down and started trouble shooting one by one .
At this point modem was undetected odin would fail to flash any firmware.
so i downloaded latest firmware 8.0. lucky it flashed and removed the FACTORY BINARY now back to stock 8.0 with no baseband and modem firmware. I did the following;
1. Flashed latest TWRP via Odin.
2.Formatted DATA then reboot back to TWRP (more drama ) your likely to face DM verify issue like i did here flash CF auto for android 7.0 but it wont give you root for some reason.
3.back to TWRP flash SuperSu for s7edge(SR1-supersu)
4.download the NVDATA,modem,and EFS for your device google search should yield.
5.flash NVDATA,modem and EFS. then factory reset the phone in TWRP
7.wait for many dramatic reboots,(reroot if you lost root)
8. then download and install ROOT BROWSER
still no network in my case at this point. i waited 20mins.
9.browse to the EFS folder in root. delete everything except **FACTORY APP**and **PROV-DATA**
10.do a full reboot
11.if no network like me, go to TWRP and factory reset.
12.sit back sip coffee and wait..
THIS IS WHAT WORKED FOR ME (G935F) i have since flashed back stock rom and rerooted and i have not lost IMEI again am now running a custom rom since 3hours ago still IMEI and network is strong. BE CAREFUL NOT TO BRICK YOUR PHONE I AM NOT RESPONSIBLE. DO AMPLE RESEARCH BEFORE ATTEMPTING THIS METHOD MAKE SURE ALL FILES ARE FOR YOUR DEVICE. ALWAYS KEEP LATEST STOCK ROM WITH YOU.
Could you tell me which rom should I flash on s7 edge locked to three UK? I bricked my phone. Don't have backup.

Don't have a backup. G935F on three UK. G935FXXS2DRA9 is what sammobile shows. But due to a scam on their website I can't create an account for 'free' download. Could you send a link with another download? Thanks

Thats because you were flashing older bootloader version on a newer bootloader..
Download this https://updato.com/firmware-archive-select-model?record=6CF8552A10BC11E89F15FA163EE8F90B
Flash it using odin 3.13.1 , also be sure to use CSC file and NOT the home_CSC..

Download this updato.com/firmware-archive-select-model?record=6CF8552A10BC11E89F15FA163EE8F90B[/url]
Flash it using odin 3.13.1 , also be sure to use CSC file and NOT the home_CSC..

I was able to bring my s935f to life but unfortunately imei and signal is gone... Now, the fact is that I had same situation with my note5 in the past and...…. have given up due to lack of ideas how to fix such complicated thing like bringing back imei. Have tried all apps from play store-/rubbish. Even today I still have that motherboard in my drawer.
BUT s7 edge looks so great that I would take a chance to fix it if anyone my kind members could provide me with instruction explaining how to do this on basic knowledge level.
I know how to flash rom using Odin., how to install usb drivers, unlock oem, usb debugging,, how to flash twrp, root the phone...… but I struggle with the knowledge about 'pit file' (what the heck is that? because my odin 3.13.1 doesn't have pit file slot which I have seem on youtube movie....) ,I am confused with the fact that I can flash let say csc ,file in AP slot in din? Ums, …. Anotherwords wouldn't be a HUGE PROBLEM if the steps given on youtube or google work!!! But they don't!!! I mean my note5 here. So I am fully aware that simple looking instruction may bring a lot of hidden problems such as 'your rom flashed ok on youtube but my exactly the same phone and rom faild…. and now the Game starts when you read on google multiple solution and non of them work for you because you missed some small detail that wasnt mentioned in the movie because that was so obvious to creator. Looking back on my previous playing with roms I can say that IS ALWAYS SOMETHING ………. so I expect a lot of stress.
If YOU know or did it before how to make my phone great again, tell me please. Otherwise this pretty beast will end up mining electroneum.... Thanks

Having Trouble Reverting G892A (GS8 Active) to Stock

Hello all,
I recently purchased a Galaxy S8 Active (AT&T). It was on a stock firmware out of the box. I found an XDA thread with a rooted G892A ROM, and I attempted to install it. I must have done something incorrectly, because the phone would no longer boot. I researched how to use Odin to flash the phone back to the stock firmware but was not able to complete that process.
This is what my phone shows during the download mode flashing process: https://imgur.com/BjhUoXb
- If you look at the last line, it says: "SW REV CHECK FAIL : [abl]Fused 4 > Binary 3"
This is the message that Odin fails on each time when flashing the stock firmware: "abl.elf, FAIL! (Auth)"
How I can get this phone back to stock firmware?
Thanks!

You will need the flash version 4 firmware on your device. It"s the 5th digit from the right of the firmware that you downloaded. My firmware is G950FXXU4DSDA so the number 4 ( from the right ) is my version number. You can not download grade to a previous when number.

Have you ever found G892A firmware on either sammobile or updato?! I've only ever seen Tmobile and Sprint firmwares...

This thread https://forum.xda-developers.com/galaxy-s8/how-to/sm-g892a-galaxy-s8-active-stock-odin-t3667204 is the only place I've ever found ATT firmware updates for G892A.
