Hello,
My reader stuck on boot and I my idea how to bring it to live also. I replaced memory card, restore four partitions structure and fill it data which I restored from damaged card. Then I make update firmware with success. Then reader stuck on boot in place as picture. I connected serial port monitor to it and in attachment is what he said. I tried to patch monitor.app with new CID of card as tutorial on this forum but he still is the same place. What is the reason that boot log include some errors?

Hi,
This is quite fortunate that I find your post. In fact my own sd card broke down completely and I am trying to resurrect my reader.
Regarding your question, from what I understood from different forums and videos, the os takes the SD card CID numer and if it is wrong (like when you copy everything to a new SD card) it simply won't boot.
Apparently there is a way to make a patch of the software so it would read this number from a file not from the card. If your old card is still alive and functional I can explain you in details.
I also have a question, how did you manage to boot your reader? When I copied the partition table and the files it did boot so I assumed that I have to install some bootloader or something.
Hi,
Your answer helped me. I bring it to live, but different way.
I messed something up in this description. Few months ago I made copy "dd" command, but not all card. I must cancel operation copy because after many hours it didn`t move forward, only display some errors. But fortunately it was enough - structure partition was restored but not all data was restored and some errors also was in this image. I write it image on new card then many probes bring it to live, patches etc. Nothing works until today. I reversed previous changes to original state and do only one modification - I modified .freezestatus file as in (
https://www.mobileread.com/forums/sh...0&postcount=93). Previously the problem was the wrong serial number of the new card that I pass to this generator. I restored all files to original state and then connected the serial monitor and I could read the correct one ( reader print it: SD card number: 00000022 ). And it works now ! Left only one problem with battery. Unnecessarily I replace it with new one , and reader works on charger and sometimes on battery but not long.
Resolved problem with battery - connector not correctly pressed down.
This solution has one culprit, TTS is not working afterwards. Only way out of this, get pocketbook.ru to send you a new image.
Not sure if they are doing this now, in times of war and boycott.
Hi,
my solution in my case works fine as in attachment. Best regards.

Huh! I hardly ever use TTS, so I didn't notice this on my Inkpad 1 with the replaced internal SD card. You are right, some certificate used for verification no longer matches and the TTS fails. Oh well, it's still better than a completely broken device.
Great that you solved everything!
As my original card stopped working I have no access to it and cannot simply clone it.
Therefore the only solution I found is to build everything from sources (i found the kernel sources for PB631 and UBoot sources). I am not really good at this and for now have not succeeded. I'd appreciate if you have any useful tips.
I cannot even build the kernel as the compiler complains (i found an sdk with a cross-compiler) for some reason
And also I asked the tech support from the pocketbook but they refused to give me the iso. :-(
@WYXUS: I think building your own OS from scratch is a bit crazy. I am pretty sure that all of the necessary software (including kernel modules) is not provided as source packages, so you cannot duplicate their system yourself. In the past, others have found someone who would make an image of their own card and send it to them. Perhaps you can get someone to do that for you, and then you can modify that to work with your own SD card.
