Moto G6 Plus - No bootable A/B slot, device not detected with adb.

[GuestD1058]

Hi,
I installed the PPW29.116-20 FIRMWARE for pie 9, it was working fine until I uninstalled magisk and now it will only boot to Fastboot mode saying "No bootable A/B slot".

The problem however it the device it no longer detected in adb to reinstall. adb devices returns no devices. This is odd as it was working fine before.

I have tried with both moto and universal adb drivers, changed cables and even changed computers - nothing it making it appear.

Any help would be much appreciated

Use Fastboot!

Requirements:

• Fastboot (because you're in Fastboot mode, lol) download links for Windows, Linux, Mac.
• fastboot images for your ROM e.g. from this thread
• fastboot flash file (contains flash commands, see in thread above)

Just unpack the zip file then open cmd/terminal, navigate to that folder and enter:

fastboot devices

When output looks like this your phone is detected:

XXXXXXXXX      fastboot

'XXXXXXXXX' is your phone's serial number.
Unpack and copy the images and flash file into the same folder as fastboot. The folder contains following files:

On Windows double-click 'flashfileNoErase.bat' (ROM thread).
Check for errors, press enter and the phone will reboot.

I just want to thank you for this, I have been crying all night because I bricked my phone just a few hours before buying it, please know that you helped a stranger greatly-

Phone of a friend suddenly died without any reason and wouldn't boot anymore. Tried this software out and it worked straight away. Requires a quick account registration however, but no biggie.

Thank you so much!
