We are working on a android 7.1.2 running on i.mx6 platform. We tried to do Android OTA update to change the version of the software. Software was downloaded from our server and then it proceeded for installation. It rebooted the system. There we could see Rings rotating with the progress bar. After some progress, progress bar got stuck at 80%.
On terminal i could only see that it was booted with recovery command with starting kernel message.
how to debug this issue ?
