To install firmware on Android 4.3, do the following:
Download
this archive and place its content on the empty memory card. Wait about one minute until such message appears:
and turn off the power.
Then place
this archive into SD card root and apply the power. The process will take nearly 3 minutes. After that the box will reset.
Please, note: after firmware update all installed programmes will be deleted, and settings will be reset to the factory one. You will need to set the right control protocol and screen resolution.
JB43_Partition firmware update should be performed once. I.E. if it has already been done, then, for example, if you downgrade to 4.1.1 and then again upgrade to 4.3, you don't need to update JB43_Partition once more.
Android 4.1.1 firmware.best regards,
