Can't connect to my phone

[gartmann]

I tried to much with installing diffent ROMs and now nothing's working anymore.

My poco starts only to fastboot but I can't connect with adb. Any other possibilities?

Drivers are all ok on the PC, because my second poco is normaly recognised.

Thanks for help.

Given unlocked bootloader, If you can only boot to fastboot maybe your recovery was deleted. You probably need to install twrp:

1.get twrp here:

2. If fastboot is working then:

If you can boot to twrp then flash a custom rom

Note that I'm unsure if above will work, only guessed

Can't flash twrp because in adb mode it shows < waiting for any device >

What happens if you type fastboot devices
