Need help. I have zenfone 5z, my device is working properly, the bootloader is unlocked, and the phone is rooted but I'm not able to get TWRP I'm getting two errors,
1. When using fastboot boot C:\Android\platform-tools\twrp-3.6.2_11-0-Z01RD.img, I'm getting FAILED (remote: 'unknown command').
2. When using fastboot flash recovery C:\Android\platform-tools\twrp-3.6.2_11-0-Z01RD.img, I'm getting FAILED (remote: '(recovery_b) No such partition').
Initially, I was able to boot into TWRP but I didn't understand a few things at that time, so I lost TWRP as it was not permanent. Now, I have tried everything except using a different computer.
Someone had this same issue he resolved it after installing the driver a second time, when the device in bootloader, but it didn't work for me.
I think this is related to partition, but I don't know much about it. So, I flashed stock ROM (factory version) but no result.
I'm very much interested in using Custom ROMs any help would be appreciated.
