Hey guys!
I'm rooted with magisk on this ROM - https://forum.xda-developers.com/oneplus-5t/development/rom-unofficial-aosip-aka-derpfest-t3978357/amp/
What would be the best way to downgrade/roll back to an Android 9 ROM? Safely.
Appreciate the help! Thanks.
I just did this process.
You just need to have your twrp updated and flash the stock rom (or other roms).
You'll lose your recovery, it goes to stock, and magisk.
I think flashing a non-stock android 9 ROM is way better, you won't lose your recovery.
If everything goes bad, you can try the unbricking tool for 5t.

So if I'm understanding correctly, it doesn't matter that I'm on the latest firmware as well? All I have to do is find a android 9 ROM (I'm probably going to do oos Aroma) and flash that in the latest recovery installed. Latest recovery being the one I'm currently on twrp 3.3
Yeah, that's it.
I was using aicp android 10 I just flashed lineageOS android 9, all worked well. I'm also using twrp 3.3 that should be OK.

Your post has many repeats - please clean it up.
Yes, when you RSD or flash a stock rom, you also change the recovery back to stock(unless you selectively do not). If you want TWRP, just flash it again.

Despite all the unnecessary repetations... You did go back to 7.0, not 7.1? Well, unless you flashed a version older than the stock version you where on when switching to custom ROM, just look if there is already a OTA. In fact there should be many. OTAs with unlocked bootloader aren't a problem as long as you don't change recovery, the only problem is flashing an older stock ROM than you had. Then you'll get an OTA too but that would brick your device
I am on an old version of 8.1 on my Pixel XL, I am unlocked, rooted w/magisk , and have newest version of TWRP.
I was browsing the roms section and most require being on the newest stock image.
So my question is, can i just flash the stock updated image using TWRP or do I have to install the image, re-root, and reinstall root?
Way back in the day i remember just using TWRP and flashing whatever rom i felt like using for the day without much extra work but have been out of the ROM gave for some time but would really like to take advantqage now of a good rom.

Hi there, I have my reasons, but I want to return back to a custom Oreo rom, I'm currently on a custom ROM with the latest firmware 9.0.7, so is it a case of downloading a earlier stock firmware, flashing in recovery? Also as I want to stay decrypted too, do I still use the v4 no Verity file on Oreo?
Thanks everyone
I am also thinking of going back to Oreo and have my reasons also. I think the best way would be to use the Aroma installer by brad which has oreo stock too.

would also be very interested if downgrade is possible. bought a used 5t with pie but need xposed and a few modules. anybody out there who tried downgrade?
Hi..I successfully downgraded my 5t to Oreo ob19 using flashable zip from below link
https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-mirrors-official-oxygen-os-t3708099
Copy the rom zip to internal storage. Reboot into stock/twrp
Wipe data/cache reset system settings
Flash zip and wipe cache then restart
We are back into the good old Oreo...
Hello,
I haven't flashed my phone for about 2 years.
I am running Firehound 8.1.0 64bit with TWRP 3.1.2-0 (I think)
Do I need to flash anything other than the latest TWRP to enable me to flash android 9.0 & 10.0 ROMs? As when I upgraded to 8.0 I seem to remember their being a bit of work involved.
Thanks in advance for any advice you can offer.
All you need is a 64bit unofficial twrp
Format data to remove encryption with twrp & wipe system & cache
As long as your stock base firmware is oero nothing else is required (if you are still on nougat firmware your fingerprint reader will not work unless you flash oero stock firmware or fingerprint fix)
The process is exactly the same for any custom rom

Is there a way to tell whether I am running Nougat or Orio based firmware? The build I am on is from March 2018. I think I remember reading about this back then but I'm unsure as to whether I flashed stock Orio or not.
I will have a look through my ROMs thread to see if stock Orio was a pre requisite.
So if I am on stock Orio, all I should need to do is update TWRP and I'll be good to go?
Edit,
I just looked through the ROM thread and the dev said a camera issue would not be fixed until stock Orio released. I have a new laptop now so looks like ill have to get ADB and fastboot back up and running then fastboot stock Orio before flashing a new ROM.
Thanks for you help

After flashing Oreo I recommended JarlPenguin's TWRP
Posted in the other forum so I'll move it here
I'm on rooted Android 9. Used the method in another thread, installed TWTP, dm-verity, WETA kernel etc. Never had any issues.
What's the step by step to upgrade to Android 10?I have the downloaded firmware and the latest Odin. Also d/l the newest TWRP. Should I update TWRP first? ( In TWRP)
Then how to flash 10 and stay rooted? Doni need to go through the whole process again to root?
Any help welcome - thanks in advance!
rooted what? stock? custom ROM? GSI?
Stock rooted. Using TWRP, Weta kernel , decrypted and Magisk.
