Please help - Back to Stock S9 SM-G960F - Samsung Galaxy S9 Questions & Answers

Hello,
I was running a S9 (SM-G640F with latest Pie Update) and flashed Lineage OS 15.1.
For flashing Lineage OS I has installed a Vendor Image for 8.1 (so the Installer told me).
I already made a Backup before flashed Lineage with TWRP and I have checked all boxes for backup up all partitions.
Now I want to go back to stock ROM and I tried to to recover and all I can recover is the system partiton.
I have tried this and then I get a Bootloop.
What can i do to get Stock Rom Working again?
Thank you!

Not tried with the S9 but when I did play about with TWRP you had to wipe system/data partitions, then restore the backup
Or just flash stock with odin and start fresh

Help :( TWRP Can't mount anything!?!?!?!?!

Today was not the best day. I wanted to try a rom out but it ended up needing 6.0 to install. I said whatever and tried to restore back to 5.1.1 (would not get past bootloader). It kinda worked... I got my my bootscreen but it stopped there. Now that I think of it, I may have needed to reflash the kernel? I couldn't perform a factory reset. It said it could not mount anything. It has been like this ever since. Anyways, I got locked out of my phone and used odin to flash 6.0 (I had a 5.1.1 file also but decided not to so I could try the ROM). I rooted it with odin and installed twrp. Same thing. Cant flash anything, backup, restore, etc. Everything else works (kinda I hate 6.0 but cant go back). I want to install xposed to get gravity box working. TL;DR I screwed up TWRP flashing a rom that needed 6.0, not 5.1.1 now I cant mount anything in TWRP. PLEASE HELP ME!!!

So is 6.0 the problem? I kinda just spent 4+ hours setting up 6.0 (shame I can't backup 6.0 thanks to TWRP)

There is no problem with TWRP and 6.01...IF you use the RIGHT version of TWRP.
If you go here you will find everything that you need including a link for the latest firmware (take this as an opportunity to update) and CF-Auto-Root and the correct latest version of TWRP:

My guess is that you installed the wrong version of TWRP, possibly for an Edge.

How to downgrade from 7.0 to 6.0.1?

Hi all,
yesterday I did the update to 7.0 via TWRP. Everything is working well, but I am missing Xposed.
So, how can I downgrade to 6.0.1? Just flashing 6.0.1 via TWRP?
Ask support. They told us when u have beta they've a special roll back build to flash? I hear something like this.
Just flash twrp, Format data, wipe everything flash the stock MM rom zip and reboot if using custom rom make sure to flash correct firmware for that version
It depends the steps you took, I think there are some threads about this but from my knowledge if you are still on ext4, unlocked bootloader and custom recovery, a simple clean flash should work...
But do check

Use the latest twrp beta version or modded twrp by eng.stk, backup data and clean flash 3.2.8 and make sure you change data partition to ext4.

Can you explain what the Android GSI is and where it gets flashed to? What OOS version were you on before you flashed the AGSI?

Android GSI stands for Generic System Image and its a system image that can be installed on treble supported devices such as OnePlus 5T I installed it to get Pie for my phone...this was before Pie for OnePlus 5T was released and I had OOS 5.1.6 before I installed Android GSI

Does the unbricking tool include a system image?

I'm going to guess that you might need a stock system image to flash. If you made a backup of one in TWRP before flashing the AGSI then you can just flash that. Otherwise you can see if the unbricking tool works. There's an all-in-one till tool for the 5T but it didn't look like it has a factory image. Worst case I can extract one for you (I would clean flash a ROM and extract the image since my current one has Magisk injected). Just let me know if the other fixes don't work.
