Hello Guys. 

Decided to do an update of my F10BT but after that device can restart itself sometimes. I used the test mode and did a scan of two NAND's Users and Ndata. In the first one, i.e. USERS, some errors popped up, while in the second one everything looks fine. Could this be the reason as my device is resetting? I will be grateful for any help.

Also here is a pic which i've done after scan.
