Inkpad 840 - new firmware = no loading or removing books etc

carltonbp · 11-01-2019, 06:49 PM

I can't add or delete files. It all looks good in windows but when I go back to ereader all the files I deleted are still there i and any files I added are not there. I've tried rolling back firmware via SD card slot but it doesn't work (gone back two versions, the process starts then goes into boots up with no firmware change).
I've tried formatting, and windows says the drive is working fine.

Any ideas?

I've had several read/write errors also before the new firmware, now they seam gone but i must say i don't trust it.

The internal memory is actually an sd card, it's rather easy to open the reader with standard plastic spudgers https://wxcafe.net/posts/pocketbook_...mbly_and_root/
just start at the side opposit of the buttons with a plastic tool, for the button side i used a steel spudger (smaller).
The sd card slots out, simply remove the kapton tape, push it in and move towards the battery.
i have pulled an image ofthe current 4gb sd card in my reader and wrote it to a 16 gb card - don't have any 4gb for the moment - using ubuntu "disks" tools - you should be able to write it with windows tools also.
I tried to extended the last partition to fill the 16gb card but was unable to do so because of an overlapping partitions error....
it also dit NOT booted with the 16gb card "as is".
so I'm now ordering a 4gb replacement card, will take bit of time before i can test...
I can share the image with you if you want , it's a blank factory reset image.
Just need an extra 4gb sd card to try it with.

edit: bloody hell, they charge more for a 4gb card than a 16gb card...

just came acros this post https://www.mobileread.com/forums/sh...d.php?t=290103 and https://www.mobileread.com/forums/sh...1&postcount=29

so it looks like making /using an image is moot

It likely will not work, since it sounds like your SD is broken, but have you tried the procedure of factory resetting your device from the system menu? Take backups first.
