Hello guys, i've unlock bootloader using motorola official method but after run command to flash TWRP the next message appears:
PS D:\Alan\Moto Z\fastboot> fastboot flash recovery .\twrp-3.2.3-0-griffin.img
target reported max download size of 536870912 bytes
sending 'recovery' (23344 KB)...
OKAY [ 0.496s]
writing 'recovery'...
(bootloader) Image not signed or corrupt
OKAY [ 0.761s]
finished. total time: 1.261s
Any way to install TWRP in Oreo?
