I am trying to flash a TWRP recovery on my Coolpad F1. I already have the img file.
However I am trying to do it with ADB and ADB ONLY. So without any app, NO FASTBOOT, or anything else... only ADB
The reason for this is I'm trying to do this is because I'm making a toolkit and I want it to automaticly flash TWRP but on my phone fastboot mode only works with the stock roms (stupid developers).
