android_device_oneplus_hotdog's Introduction

TWRP device tree for OnePlus 7T Pro (hotdog)

Disclaimer - Unofficial TWRP!

These are personal test builds of mine. In no way do I hold responsibility if it/you messes up your device. Proceed at your own risk.

Compile

Install repo tool from here: https://gerrit.googlesource.com/git-repo

Initialize and sync minimal manifest TWRP: https://github.com/minimal-manifest-twrp/platform_manifest_twrp_aosp

Clone device tree:

# Assuming you're in the synced TWRP repo
mkdir -p  device/oneplus
git clone https://github.com/arminask/android_device_oneplus_hotdog device/oneplus/hotdog

To build, execute these commands in order

source build/envsetup.sh
export ALLOW_MISSING_DEPENDENCIES=true
export LC_ALL=C
lunch twrp_hotdog-eng
mka adbd recoveryimage

To test it:

# To temporarily boot it
fastboot boot out/target/product/hotdog/recovery.img 

# Since 7T / Pro has a dedicated recovery partition, you can flash the recovery with
fastboot flash recovery recovery.img

Issues

  • adb connection only starts working when user decrypts userdata on TWRP bootup prompt. Not sure if it's by design, but expected functionality is adb starts working immediately on bootup. This will mainly affect users who use roms with different userdata encryption, to get around it, start adb sideloading and then cancel it, adb connection will start working normally.

android_device_oneplus_hotdog's Issues

Fix ADB

The ADB connection on PC will only start working after the user enters the PIN and decrypts userdata on TWRP bootup decrypt prompt.
If you don't enter your PIN (or can't because your ROM doesn't use FBEv1 and the prompt doesn't show up), ADB won't work.
To fix this, qcom/usb init scripts need to be fixed. I haven't found a fix for that yet, if anyone here knows how to, please make a pull request :)

Workaround: Start ADB sideload and then cancel it, then ADB connection will start working normally.
