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

You still have M919 bootloader, so just flash a recovery with Odin
Edit: the only thing that you updated to 5.0 is the system and kernel

so basically i didnt have to flash that to start flashing lolipop roms huh.....lol....i thought i did because i had so much trouble with nb4 roms... thought had to update something like modem...thank you. i will have new rom soon... nice.
Hello guys,
following situation:
Long time I had a 4.4.something Rom installed. Before I flashed a custom Lollipop rom, I followed the advice to just go back to stock and let it update to Lollipop so that the firmware will be updated accordingly and I won't run into problems when flashing a Lollipop Custom Rom. Everything worked fine. Now I had to send my phone to HTC for display repair and just to make sure they won't nag about the custom Rom I reflashed some older stock rom via TWRP backup I found here, I think it was a 4.0 or so. The question is, does this also affect my phones firmware or is it still on the current newest level? So when I get it back, would I need to update to stock Lollipop again before flashing a custom rom or can I go for it straight away?

It won't affect your firmware.
Okay thanks, so Firmware should still be up to date and I can flash a Lollipop Custom Rom. I don't know what they do at HTC repair, if they only reset it or if they also update it, well I'll see.
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...
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.
I have a LM-G710ULM on android 8.0.0
Sec patch sept 1, 2018
Kernel 4.9.65
Its never been bootloader unlocked or anything and internal mem is almost full so was going to wipe it and factory restore but figured now would be a good time to look into unlocking bootloader and flash a custom rom.
Im just looking for good performance and reliability, I have not flashed a custom rom in years and not at all with this phone so is there any up to date guides for people with no clues?
Any rom suggesstions?
Thanks!
You may try to upgrade to latest android 10 official firmware first. You will not flash anything custom but at least you will get an update from android 8 and start to familiarize with flashing.
And even if you want a custom ROM, the most recent ones are based on latest android 10 official firmware, so you have to install that first anyway
