I have some new data for you guys.
From OpenVIX 6.3
-Tried to restore the backup that had issues on slot 13, the one that seems problematic and didn't install returning the same issues as from OBH.
-Tried to install OpenVIX 6.4 image (not a backup) on slot 13 but didn't install.
-Installed OpenVIX 6.4 on empty slot 14 and installed with no problems.
At this point I thought there was a problem on slot 13 as you
@Ev0 supposed.
-Tried again to install the bugged OBH backup on slot 14 but again didn't install. Confirms there is a problem with that backup.
From OpenATV 7.3
Made a backup from it's Image Manager of the OBH 5.3.010 that I have on slot 7.
Restored the backup I just made on slot 13 (the buggy one) and it installed with no problem.
This should prove that the slot 13 is ok.
That's it for now.
