I'm new to this Asus 5Z, used to flash my old HTC One M7 until unofficial LOS 17.1 but decided to change to a more powerful smartphone.
I tried (really tried hard) to follow your tutorial. My computer is W7 with adb & fastboot working (installed latest platform-tool), unlocked BL thanks to Asus apk, did all the things without issues until the step 10. When I flashed the rom (latest LOSMicro-G 18.1), twrp remains flashing and never stops.
And I did something stupid... rebooted to bootloader, as fastboot wasn't working (no device detected) i rebooted twrp, but adb wasn't working neither. And I... formated data, and wrongly rebooted to bootloader, thinking that I was going to try again.
I'm now stucked into bootloader (fastboot mode), it's impossible to power off the phone, I don't have twrp anymore and the phone isn't recognized by fastboot devices comand. On my computer, I removed android and asus drivers, tried to install them again, but I still have a yellow warning and a code 10 error.
So I'm unable to communicate with the phone and flash anything.
Can someone help me ?
What is the code 10 error? Also, did you try hard rebooting back to fastboot? (long press vol+powerup for 15-20sec). You can try edl as a last resort. Folks over at https://t.me/ASUSZenfone5ZGroup might be able to guide you better.
