I have this unit also and am trying to get the touch screen to respond. has anyone verified the manufacturer? I'd like to just reload the system. I've done computer repair since the mid-90s but avoided android and IOS devices until now so I am now looking for open-source tool recommendations preferably tools that can be run off of a pc or laptop. any help or tips would be appreciated. Thanks!

I was able to get root on this, extract attached zip to root of flash drive (fat32 format is required) and attach it to the 4pin USB. Then short the F1 pin (next to the wifi antenna - see attached image to ground. You can also check the pin maps on the device for F1. Once you have it grounded, just reboot the device and it should flash twrp to the unit. Once you have twrp flashed, install terminal emulator and type "reboot recovery" and it should start twrp after which you can install magisk for root.

This files were tested on 1gb/16gb version from 4PDA.

I managed to kill all the gapps on my device and now android auto doesn't work with the ZLink app. If anyone can share the twrp back up of system apps folder.

Thanks a lot! It worked, had a different setup of the rear connectors but found the one that was the same.

Yes, here's my layout.
There is only one male connector that corresponds to the picture by WW3.

For 10 seconds? It didn't work the first time for me? Is the Flashdrive Fat32? Did you transfer the files to the flash drive? It should start automatically, follow the instructions to the letter.

Yes, everything unplugged.
Then connect the two pins with the tweezer, then insert the USB cable with your flash drive in it, then insert the power cable while still holding the tweezer in place and continue to hold it for atleast 10 seconds after you have inserted the power cable. Hope that helps.
