Unable to unlock bootloader for Asus Zenfone Max Pro M2

[RikSantra]

I have been trying to root my Zenfone Max Pro M2, I was following this guide by the forum, however when I installed all drivers and rebooted into bootloader using adb, the phone's screen showed 'CSM Fastboot Mode' for a second and then everything became black with only a small text on the upper left corner saying 'press power button to shut down' on pressing power button it only booted to normally. On using fastboot on the black screen itself, it showed no devices attached.

Yes, I downloaded the correct firmware file,
pressed on browse,
selected the zip file
pressed on start.
then it restarted my phone and told me to select the 'Apply update from ADB' and then it told me to press on the 'resume' button and I did that, the progress indicator showed up and then suddenly disappeared and the resume button appeared again. I spammed it and yet it didn't seem to work.

Do you have a usb hub?

Try this if it nothing else works
After running this, fastboot commands should work.

tried it just now, it's still the same

 

[Kenora_I]

Welp that's it i guess. Unless you have some usb 1.1 stuff lying around or an old cable

Running intel or amd on that laptop?

 

[Kenora_I]

Worked well

Broh. For last two days i also facing the same issue. Today I made it.
Without closing 'command' box in pc, and removing usb,,... keep restart to fastboot mode.

Or

Restart pc without unplugging usb(mobile should be on fast boot mode) direct open flashall_aft.bat/ flashall_bat.cmd....

I tried this and well, the screen stayed at CSC Fastboot Mode for like 30 secs. The flash tool was stuck with the following on it:

------------------------
Begin fastboot flashall
------------------------
Earse Data: Yes
Support All device

but after a few seconds windows played the sound it plays when a device is connected and the the screen again went back to being black with that same error.

1. Start an admin PowerShell (or admin CMD if you want). You can right click on the start button and select "PowerShell (Administrator)".

2. Enter the following commands to create 3 registry entries.

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "osvc" /t REG_BINARY /d "0000" /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipContainerIdQuery" /t REG_BINARY /d "01000000" /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipBOSDescriptorQuery" /t REG_BINARY /d "01000000" /f

3. Restart your phone, let it enter fastboot mode, and then connect to the computer. At this point, the unlocking should proceed normally, and the device no longer disappears from the "fastboot devices" result and Windows Device Manager.
Use at your own risk, I sourced this from a old XDA post about windows and a Mi Mix with the exact issue.

Well, I mean on this thread someone had the same error and said that reinstalling the correct drivers worked.
