Hi,

This error:
'Verifying eMMC firmware fail: NO Error'
happend because you didn't disconnect everything from eMMC (all lines : 1.8V, 2.8V, CLK, CMD, DAT0) before making short TP to GND !!!!

Some current leakege apply from CMD, CLK, DAT0 box lines and eMMC goto wrong state, when disconnect only 1.8/2.8V power lines.
eMMC wrong state cause 'Verifying eMMC firmware fail: NO Error'
No Error - means no communication error, only firmware update error occurs.

Disconnect everything from eMMC, make short TP to GND, plug eMMC power then remove TP to GND, plug into box, make sure that eMMC Identify 000000, start update firmware again. eMMC Update Firmware should be OK this time !!!!!!!!!

DON'T FORGET TO REMOVE TP TO GND CONNECTION BEFORE FIRMWARE UPDATE, BECAUSE WILL BE SAME ERROR: 'Verifying eMMC firmware fail: NO Error' !!!!!!!!!

Regards Viktor
