I don't remember details, but twrp-3.4 is for android 10.
Btw. I made some fixes for this rom. I pushed some patches for review, but they seem to be not interested in it. Maybe people are focused on android 11 now.
If someone is interested:
- Wifi can work with 150Mbps speed. I tried to enable 5ghz there too, but you only need gChannelBondingMode24GHz=1 and gForce1x1Exception=0
https://github.com/deveee/android_device_asus_X01BD/commit/2bb9d29bb5cf6312a9acd3b6c67390411d047e54
- ogg files cannot be played on most players by default, here is a workaround
https://github.com/deveee/android_device_asus_X01BD/commit/27d1e4a64acb735787a49007b6259b9cd7e4c6c2
- Not sure if real bug, but there is incorrect path in "com.qualcomm.qti.imscmservice*.xml" files. Fixed in extract files script.
https://github.com/deveee/android_device_asus_X01BD/commit/3f8046f641c4f132dd34bfba69e63abb57e3f63d
- Don't complain about high media volume, I just hate it. It has to be compiled from sources to enable it
https://github.com/deveee/android_device_asus_X01BD/commit/f070d457ac6632435c1fb54c97beda33935e4538
- Add support for gamepad devices to kernel
https://github.com/deveee/android_kernel_asus_sdm660/commit/2a49f7b5a4981d541fe36a3d14af177e010e19a2
- Again not sure if real bug, but my selinux was printing error message each 3 seconds. It's just a hack, I can add proper sepolicy file if upstream is interested in it
https://github.com/deveee/android_kernel_asus_sdm660/commit/1c35ac14faee7557a738e6303f96f61f3fc76f52
- Also sound is a bit buggy, eg. phone speaker plays only single channel istead of both left/right channels. It can be fixed by copying lib/audio.primary.sdm660.so, lib64/audio.primary.sdm660.so and etc/audio_policy_volumes.xml from stock rom. I think that it can be also fixed by compiling audio drivers with different options, but I didn't find what's wrong. Using stock libraries is good enough.
Some of these fixes are not ready to push them upstream, but they are good enough to use on device. I can improve them and push for review if upstream is interested.
