My Meizu MX4 Ubuntu is stuck in a bootloop ... something is wrong with the OS image.

I can get to fastboot. When i plug the device into windows 10 it never gets an ID. In ubuntu i get the device recognized on certain ports with certain cables. (newer cables seem to fail).

Fastboot devices shows my device with correct serial. lsusb shows incorrect information.:

Bus 001 Device 026: ID 0bb4:0c01 HTC (High Tech Computer Corp.) Dream / ADP1 / G1 / Magic / Tattoo

fastboot flash recovery recovery.img always gives:

    sending 'recovery' (11220 KB)...
FAILED (data transfer failure (Protocol error))
finished. total time: 0.575s

as a test i tried :

    username # fastboot erase recovery
< waiting for device >
erasing 'recovery'...
OKAY [  1.026s]
finished. total time: 1.026s

now i have no recovery and cant add one.

Can anyone please assist?

as info when i use a newer cable i get this in dmesg:

It seems like an usb connector problem to me. Maybe claiming to Meizu or trying a whole lot combination of usb cables/usb hubs/computers? I have had some of this weird behavior and still need to find some time to fully debug and claim to Meizu for the hardware if needed. Will update when I test further.

UPDATE:

I failed to get fastboot working. I downloaded flash tool for ubuntu and got a scatter image from XDA.

I was able to write the whole catter to the phone by plugging it in and holding down the volume down button.

Phone now works perfectly again.
