What updater? The TMobile version doesn't have that, OTA only

It seems you don't know the difference in software for the TMobile software and international(which is fine) but you're really looking like a donkey insisting you're right, now please unless you have an answer to my question or have anything useful to add to the thread it's probably best to stop cluttering the thread

I recently learnt about this difference. You might get a better answer if you ask on the 7T Pro 5G forum (apparently it's different enough that they made a separate forum for it), since I doubt many people have the 5G version here.

TWRP 3.3.1-43 for OnePlus 7T, 7T Pro, 7T Pro 5G (hotdog) by mauronofrio:

Fixed Decryption on custom roms (still broken on Oxygen OS);

Added unified script;

ROM flashing is working;

System, vendor and others logical partitions can't be mounted (it's not a problem for the others things);

Magisk and kernels can be easily flashed;

Fixed TWRP flashing, now you can flash the TWRP directly in the recovery partition from fastboot.

[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] knpk13:
7T series (just like the 8 series) has a recovery partition (well, technically 2 recovery partitions because A/B slots) so recovery should persist through normal use. Expect OTA updates and flashing OOS zips to overwrite the recovery partition with stock recovery though.

The thread for the 8 series TWRP has some relevant discussion if you want to read it.

TWRP can't access data to flash Rom

Ok I'm lost here, I'm trying to install TWRP on my Onelpus 7T Pro Im on stock OOS 10.0.9 HD01BA. I am interested in installing Havoc Rom. I boot into TWRP and I can't access data. So do I need to install another custom Rom using payload dumper flash through fastbootd and then flash TWRP? If thats the case then this is useless, am I missing something do I have to flash TWRP on both slots? Please help. Thanks
[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] knpk13:
If you're coming from OOS, you'll have to format data before TWRP can read it as decryption doesn't currently work with OOS (only works with custom roms).

Hello!

As I understand it, thanks to the respected mauronofrio, now I can flash TWRP.

I'm not sure I correctly understood the explanations in the topic header. Therefore, two questions.

Why do the instructions indicate two (recovery_a and recovery_b) firmware paths? Is it a necessity? Or just two equally likely possibilities?

Downloading to TWRP continues to be possible only through fastboot? Or do other download options appear?
[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] slapman:
Hi, is there a guide on how to format data? I don't know which format to chose while on OnePlus 7T pro stock OOS 10.0.9. I would like to be able to keep a backup of the setup I currently have, while flashing custom roms. One thing I've incurred while on custom RR rom. I flashed Havoc Rom it seems it installed correctly but it stayed in a boot loop when I booted into recovery TWRP was no longer available. After flashing Havoc do I need to flash TWRP before booting into system?

https://xdaforums.com/7t-pro/development/recovery-unofficial-twrp-recovery-t3989333/post82921497

As mentioned here, format data and backup is broken in TWRP right now. Use "fastboot -w" in fastbootd to format data (keep in mind this will remove all files, even from internal storage, so make a backup manually and store it somewhere else). Follow the instructions in the thread of the ROM you're flashing; I think they're all mostly using fastbootd for the initial flash and then OTA updates. I have not personally tested flashing ROMs using TWRP so I can't comment on that. However the OP has stated flashing ROMs, magisk and kernels work. So if flashing ROMs works, just use fastboot -w to format data before you first boot into the new ROM or it won't work.

Since TWRP backups don't work, I'd recommend something like Migrate (supports split apks) or Titanium backup (doesn't support split apks) for backing up app data. Internal storage can be backed up over ADB or MTP. System is read-only so doesn't need to be backed up. You'll still have to go through ROM setup every time though, which is unfortunate. I haven't found an easier way to try out different ROMs. I tried out all the different custom ROMs a month or two ago but decided to switch back to OOS for now.
[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] arvindgr:

[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] knpk13:
I see this comment a a lot and it doesn't make any sense.

Currently the only major problem with TWRP is support for dynamic partitions, and it's a WIP. That's not something I'd expect to magically get solved with an android 11 update.

Your phone has two partitions (google for A/B android partitions), so you want recovery on both of them. TWRP will tell you current one or just run adb command to check.

You have to be in fastbootD (handling Dynamic partitions, curse brought by Android 10) and not general fastboot to flash them.

ALWAYS CHECK

NEVER ASSUME !

If you have NOT flashed / installed TWRP on the McLaren edition, then YOU DON'T KNOW. And that's perfectly ok to not know.

It's NOT OK to "assume you know". That's potentially dangerous.

Anyways, it says on the telegram group that this supports the McLaren edition, but I don't know if that means it has limited function when fastboot boot 'ing,

It doesn't state anywhere for sure and no one has confirmed that you can actually fastboot flash / install this thing permanently on McLaren phones.

There is a guy who just started the whole process so I'll have him test installing TWRP 3.4.0-2.

Well, to be honest, I haven't followed this scene in a long time! I still have the Mclaren, yes, but I really haven't been on XDA in quite some time. Crazy year and too busy to be honest.

Because oneplus has implemented keystore (what handles the encryption) differently for 7T/Pro.

How to backup /data?

Data partition is the most important thing to backup, all other partitions are easily flashed or backed up with "dd".

I tried to backup /data when device had a screen lock pattern, TWRP failed with "extractTarFork() process ended with ERROR 255".

I switched off the pattern, TWRP made a backup seemingly successfully.

Then I tried to restore the backup, TWRP unpacked it seemingly successful to 99% and then again ""extractTarFork() process ended with ERROR 255".

Maybe somebody knows a workaround?

Or maybe backup/restore can be done somehow from "ADB Shell" with some Linux TAR command?

does not mount /vendor and /system_root, someone has got to disable force encrypt? i have installed this twrp version and flash magisk correctly but i need to disable encrypt and it seems impossible. I've got OnePlus 7T. Thanks in advance

i've done this:

3-boot again into recovery to mount /data correctly

4-Install magisk and dm-verity-forceencrypt-disabler,

5-boot into system.

Always encrypted, magisk works well, i've got root but imposible to install nethunter as it needs /data partition mounted as rw

Mounting /vendor and /system_root is not necessary since you can't modify them.

And format data is broken, which is clearly stated in the first post.

I'm not sure why disabling encryption is necessary? Just adb push zip to /cache and flash?

If you actually want to disable force encryption, check out arter kernel with f2fs. Otherwise no way.
[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] muadibb:
This is why disabling encryption is necessary:

Nethunter install manual

IMPORTANT NOTE for Android 9, 10, & 11 users: Please ensure that you flash the Universal DM-Verity, ForceEncrypt Disabler and format the data partition prior to installing NetHunter.

Magisk does not support user context changes on encrypted data partitions, which leads to errors when connecting to the Kali rootfs via ssh (i.e. "Required key not available") if the data partition is encrypted.

I think FORCEENCRYPT DISABLER is not working because of not mounting /vendor but not sure, i've tested several times in different order with same result, i'm attaching a log from twrp, don't remember if i tried this time dm-verity-forceencrypt-disabler and then magisk

Thanks for the info about arter kernel solution!!
