OK, thanks. Can I please see what the kernel UBI is doing?

Could you please enable this option in the kernel config:

Device Drivers  --->
  <*> Memory Technology Device (MTD) support  --->
    UBI - Unsorted block images  --->
      Additional UBI debugging messages  --->
        [*] Additional UBI initialization and build messages

Then attach the UBI device, reproduce the problem, and give me UBI
output. I want to see what UBI finds on the flash. Please, refer
this section for more information about how to capture the debugging
messages:
