FAQ/Info

Why run in recovery?
- TWRP provides an environment with fewer services fighting over the USB controller. checkra1n relies on a highly controlled data flow over USB.
Will this work with all Android phones?
- No. If you could already do this manually in TWRP, yes definitely. My Nexus 5X (2015) and Mi Mix 3 (2018) both work.
