Android box stuck?

Question

linux

We have: Android box TAPPRO. Hangs on the splash screen. When you try to flash it, it stops at 7%
Initializedisk error writes. Well, in general, apparently the problem is with emmc. But I would like to be more specific. There is a download log.

I wrote out all the lines containing errors:

What is the reason? How to fix? NAND replacement?

Answer 1

To clear your conscience - you can still check the food. No "swelling" or "leakage" of capacitors. The presence of voltages close to 5, 3.3, 2.5, 1.8, etc. Absence (20-40 mV max.) voltage ripple.
