G950U1 Oreo to Nougat Possible?

Is it possible to flash back to Nougat from the Oreo beta on the US S8?. I've tried searching but I could only find information on the international version.

Follow the SMG950U instructions. Basically getting BLQ1 nougat flashed on the phone and then getting the update.zip for CRB8 and applying that in the Vol UP+Bixby+PWR boot.

Connect to pc with smart switch and it will give a downgrade option. At least it does for mine...

Need CRL3 update.zip

Hey guys,
I am currently running Android Pie beta4 on my S8 G950F and I am looking to downgrade to CRL3 to be able to get the official Android Pie update.
I need to do this update using the SD card because I do not have access to a Windows device, or can someone give me some details how could I make the android pie update to my S8 using a Mac ?

There are no updates to downgrade. You need to flash via odin. Go find your needed G950F ... 4DSBA firmware and flash home csc. If you have issues, flash csc (wipes phone).
¡BBB!

Get yourself a Windows VM or see if you can get Odin and SamFirm on Mac.

EEA 10.3.30 to 10.3.2.0 = anti rollback brick?

Hello.
Hope you can help because I'm kinda confused atm
My device is redmi note 7 lavender, came stock with EEA (european global) rom.
I recently unlocked the bootloader, installed twrp, tried a few roms (xiaomi.eu, crdroid, phh-treble gsi, etc). Currently using crdroid without issues.
Previous to all this I was using stock EEA 10.3.2.0 firmware and then sideloaded ota for 10.3.3.0.
According to this post this phone has ARB
What I'm wondering is if I were to go back to stock firmware, would I brick my device? Because the only available fastboot version for EEA is 10.3.2.0 which is older I guess, but I'm not sure exactly how ARB works and it that would trigger it.
Thanks in advance

I recommend that you do not return to the previous version, sometimes the ota bring changes in the bootloader, and you can leave it hardbrick as it happened with several Motorola, even with devices that have a Qualcom processor. Expect that someone else has done it or that the software is released to an equal version.
start to investigate the changes that were added
I leave this link you fence to interest move from the EEA to the global version

If you're asking specifically about turning back from 10.3.3 to 10.3.2, then there is no problem (I went from 10.3.3 to 10.3.2 to 10.3.3 again and everything is ok).

My RN7 is global, came with 10.2.3.0 as stock, I updated via OTA to 10.3.5.0, and I was wondering if I try rolling back to 10.2.7.0 (As I didn't find any rom of 10.2.3.0 for global PFGMIXM) it will trigger the ARB? thanks in advance (both have lvl 4 in adb query)

Don't. Just bricked my phone.

Sorry to bother but, did you bricked going from which-to-rom, using TWRP or the mi-flashtool?

Rolling back firmware only through twrp, trying to get previous drivers for international version which bug less on proximity sensor.
As the phone is unlocked I might have found a way to restore from brick without physically opening the phone. Will keep you updated.
Edit/Update: yipeee!!
Need to completely flash the phone based on the procedure detailed here. And reflash whatever custom ROM afterwards as you get back to stock.

Just rolled back from Global 10.3.5.0 to 10.2.7.0 with MI Flash Tool (fastboot rom type). 0 problems, seems you can rollback from your MIUI 10 ROMS of the same version(EEA with EEA, Global with Global, etc, and of course that these roms have same ARB 4), at least worked for me, posting this future records.

Actually firmware tool (as opposed to twrp) is the way I reset ARB.

Downgrade from Pie to Oreo

I have a G950F unrooted and with stock Pie. Is it possible to downgrade to Oreo ? Of course I'm keen to root and unblock the booloader

Depending on what firmware version you are on. Due to bootloader(binary) versions increasing you cannot downgrade to a previous version, only a previous version with the same bootloader number or a higher version.
Basically if you on version 5 (bootloader/binary) you won't be able to downgrade to Oreo.
The only way is if there is a custom rom that has an Oreo favour to it.
You can still root on pie.
