A while ago I’ve upgraded my Nebula Mars II to the V1045 Beta Firmware (with Google Play Support).
As was really good, until it started not to turn on by sliding the lens cover down.
The issue is that it seems to try to boot, but halts the process. I can hear the fan starting for a 1-2 seconds and then it turns off again. charge lights blink. sometimes it tries multiple times to boot but nothing happens.
After a 15-20 mins of a random ritual of plug into outlet, open cover, wait, repeat, eventual reset I can, sometimes, get it to work again. Once it’s on, all is good again. no issues.
It could be beta firmware related. To ensure that, I’d like to get it downgraded to a stable version firmware. Since it has been manually upgraded to this beta firmware, I don’t know how to revert back to the mainstream firmwares to test.
Any hints ?
Is there somewhere to download these firmwares and manually update it ?
