Custom OnePlus 8T+5G OS - OnePlus 8T Questions & Answers

What are some custom operating systems I can use for the OnePlus 8T tmo edition? Most of the custom ones won't work due to the fact that I have the TMO edition. I have also unlocked my bootloader, but I can't find a custom recovery. What should I do? I'm really new to custom OS. Any help is appreciated.

You can install lineage os

Convert to global via MSM and you'll be able to get rid of TMobile restrictions but you still have to pay off the phone to get SIM unlocked.
After converting you can install custom recovery like Orangefox and flash custom ROMs

Carrier Version Bootloader Locked Workaround for Custom ROMs?

Could you in theory install a custom ROM by rooting the Pixel 3a with King(o) Root then flash recovery via TWRP app or Flashify the img. To then install a custom ROM that from TWRP from there?
I have Sprint version but I'm just wondering in general

That kingo stuff doesn't work. It's a scam if you ask me. And you need to request your carrier to unlock your sim before anything. Then you can proceed to unlock bootloader and whatnot.
Even if there was a way that wasn't a total scam to get root on your verizon locked device, TWRP is broken on any Pixel 3a running Android 10 due to partitioning design changes breaking it. So even if you had TWRP installed, you couldn't actually use it.
The only way to install custom ROMs for now is to flash via fastboot.

Help with flashing ROMs on T-Mobile version

I have a T-Mobile branded OnePlus 7 pro, I got the code from T-Mobile and I unlocked the bootloader and flashed TWRP and Magisk. My question is, can I just install any room or do I need to convert to global international using the msm tool first?
If I can just flash directly, how do I install the open Beta? The instructions say to to do it manually in settings, but that's not an option in the T-Mobile ROM, and each ROM seems to have very specific instructions on how to flash using twrp. Thank you for any assistance.

flash OnePlus 7 international rom to tmobile

I have a TMobile OnePlus 7 pro (on cricket) rooted(magisk), unlocked carrier, unlocked bootloader, twrp. Can I flash one of the international custom ROMs (like havoc, crdroid or resurrection more specifically an Android 9 version) without flashing the international firmware? I had problems when I previously tried to convert to international that the phone wouldn't recognize my sim even after taking the OTAs.
If not, one I flash to international firmware and do the ota's can I flash an Android 9 rom over oos 10.x.x? I've been out of the game for awhile and the whole ab partition scheme along with how ROMs are for this phone is a bit confusing. Thanks.

Firstly how did you unlock the bootloader without going to the international oos. What? Unlock sim and bootloader token?

Yes I carrier unlocked and then flashed the unlock token.
If I don't flash international can I flash custom ROMs or do I have to flash international first? And I I do flash international and then do the ota's, can I flash a custom android 9 rom ontop of oos 10.x.x(10.3.5 I believe is the newest)?
Your oneplus 7 pro is working on cricket? I unlocked my t-mobile op7 pro via tmobile and flashed the global rom and updated. I sold the phone to a friend and he's on cricket. Cricket is telling him the phone isn't supported but prior to selling it to him I put his sim in it and it worked. Made a call and browsed internet. When he went to set it up after factory reset his sim card got locked by cricket and the phone kept turning off with the only way to power on being holding all buttons to enter fastboot. So if I put the t-mobile rom back on it will his service work?

I flashed the global rom with no issues. Sim card didn't work initially but after the first update it worked no problem. It takes ota's with no problem and I didn't even have to unlock the bootloader. The msm tool and op file did the trick

Your phone is China or Global?
If your phone is China, do not flash any version of miui 12.5. It will disable Google services.
Also for all phones, do not install a very old version of miui because it will brick it. Try to remember the version of miui that you was on before you jumped to xiaomi.eu, and install a newer version of that.

What stable A12 ROM for one plus 7 pro

I have a European 7pro running stock A10.
I would like to flash a A12 Rom.
What is the most stable Rom at the moment.
I assume the following
Bootloader needs to be unlocked.
I need twrp for back up
Do I need magisk to install?
ROMS come with gapps.
When I tried to flash a custom rom about a year ago I got it to work but no matter which rom I used it would not recognise the sim card and v therefore I couldn't use it as a phone and use mobile data. Please advise which one and a guide. I just want the basic A12 features I don't need anything fancy. Just bored of stock A10 and would like some additional functionality of A12.
Thanks Bart
