Hi Jeanrhum,
Thank you so much for your support. I have followed your instructions and found that it still did not work (I have attached a link of a video showing the error message I get). I then attempted again using your code for both ext files and still no joy. I tried so many different dtb files and eventually gave up on this. I did attempt to update the software via the pin at power (Shown on the video) as the update via the android setup screen does not show any files to update the system with,
Also, fyi I did rename the u-boot file (i.e. u-boot-s905x-s912 renamed to u-boot.ext).
Also, Just want add I have tried various SD card (all Sandisk - ranging from 8 to 128 GB) also MyGica 1960 allows to update via USB and the video shows my attempt which sadly fails.
I would have replied sooner, but this forum has restrictions on how many replies I can make daily.
Do forgive me the video recording is a bit poor.
Any help would be much appreciated.
Cheers
F.
