I am trying to follow this tutorial https://aiomobilestuff.com/motorola-moto-g7-power-xt-1955-root-twrp-unlock-bootloader/
fastboot flash recovery twrp.img
(I renamed my twrp.img to recovery.img) gives me this error
and the command
fastboot boot twrp.img
boots my phone into twrp and it freezes it. I am able to work again with my phone only after restart. Is there a way so that I could root my phone? Thanks in advance!
