The SD card from the PB626 v1.6 (4 GB) became non-functional. I still had a v1.9 device with broken screen and moved the 8GB card to the v1.6 board.
At first the touchscreen did not work at all. I transferred a firmware file to SD card and initiated manually a firmware update to 5.14.1225. During update some funny messages about voltage settings were visible but if I remember correctly the update aborted anyway.
Now the reader appears to be fully functional again.
However, yesterday I tried to update to the new version which is 5.20.1157 in order to be able to root the device.
The update aborted. The last messages were:

The device will turn off in a few seconds

Any ideas which files from the defunct SD card to transfer to the v1.9 card?
I do find the corresponding wave form file on the defunct SD-card.
I damaged the slot of the SD card slightly so I have to glue the card into the slot. Thus not so easy to assemble and disassemble ...
Any suggestions what to try first are welcome!
