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

Hi, I have a question, could anyone explain to me how the 7 Pro differs from the 7T Pro? They are practically the same phones, but TWRP on 7 Pro is fully functional, and on 7T Pro half of the function does not work, why? I just want to know what makes these models different

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?

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).
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?

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.

Hopefully atleast our device gets better recovery support with A11 update
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.
