Love your work, tool looks great however I'm having trouble using it to flash TWRP. It goes through downloading boot.img and all that fine and gets to the menu (Bootloader is 'unlocked' but when I hit 2 to flash recovery.img I get this:
Type 1, 2, 3, 4, 5, 6, 7, 8 or 0 then press ENTER:2
target reported max download size of 268435456 bytes
sending 'recovery' (13794 KB)...
OKAY [ 0.481s]
writing 'recovery'...
FAILED (remote: Flash failure: Not Found)
finished. total time: 0.497s
"Recovery flash done. Bootloader unlocked. If you flashed original recovery, change bootloader state manually."
Press any key to continue . . .
And then it starts up in the regular Xiaomi recovery. Any idea what I could be doing wrong?
I think, it's a driver problem. When you will be booted into fastboot mode by the Toolbox, open device manager in Windows and have a look what kind of drivers appears there. You can try to use Xiaomi drivers from Drivers subfolder inside the Toolbox. Extract them somewhere, choose "Update drivers" in device manager, point to extracted folder. Probably Windows will say something about signature or something else. Just ignore this and force driver installation. Then all should work. Maybe you will need reconnect of the device and re-run of the Toolbox, but I don't think so.
