Hello.

As You can see from your Software log, there was an error with writing data:

Quote:

Write data verification is enabled.
Writing GPT partition...
Write verification error 1. Possible reasons: damaged or write protected eMMC.
Disconnected.

This error means that device has HW issue (damaged or write protected eMMC) and Software can't write data to device. If you had investigated this issue more thouroughly you may have discovered that on many Hynix eMMC chips there is a bug with write protection (probably manufacturer's feature for saving device/user data). Currently for such devices only solution is a chip replacement.
