You can resize the first partition (the exportable internal filesystem); I did it by changing the size in the partition table with a hex editor. My device did not recognize the new size until I reformatted the internal memory with its System utility. You might be able to use some tool to modify the partition table, however all the ones I tried balked at the overlapping partitions that PocketBook sets up.

The link is dead Maybe anyone still has this image? Or anyone could make one from their restored device?

I am trying to follow the steps and make my own modification, but ending with bootloop...

All you need to save this image to some drive under Linux and run the following command from the folder where it saved as su:

gunzip -c pb626.img.gz | dd of=/dev/mmcblk0 bs=1M status=progress


Replace /dev/mmcblk0 on your actual SD card device. You can find it with:

fdisk -l

Good luck!

Ok, I solved my problem.

Firstly: "sw_20170718_626_W_5.14_1225_5.12_CI_gdb_pn_630_us er" didn't work for me – infinite hourglass when booting. I mean process of patching monitor.app and adding original serial text file didn't work. BUT with "sw_20160922_626_W_5.14_791_5.12_CI_gdb_pn_630_use r" same process worked perfectly.

Secondly: as I used Dropbox to sync my books, I wanted an update (as only from version "W_5.14_1225" updates to Dropbox API were included). So I started researching more and I found that there is a way to "rebind" any Pocketbook to any SD card.

Here is the link to forum post (in Russian): link.
Here is the Google translation: link.

Basically you can download an app (linked in the above post; reposting here as well: https://yadi.sk/d/bo7FNPlRy_fMzA ) and then use it to regenerate ".freezestatus" file (replace existing one with the new one at "/mnt/sde9/.freezestatus") with a command:
Code:
./serial --serial_number YT4517001251004000Y5 --sd_serial 0x12345678
After this it just works WITHOUT replacing monitor.app and so on.

P. S. Russian post includes much more details and more usefull info, but for basic "clone the SD content from original to new one and make it work", this replacement of ".freezestatus" is enough.

Note: I completed the following steps on my linux machine because i found it much easier as i don't have much experience with windows.
1.Create a copy of the sd card image using dd.
Command: sudo dd if=<sd_card_devide_location> of=<path_to_output_file>
Example: sudo dd if=/dev/mmcblk0 of=~/Desktop/pb_sd_image.img
2.Find the cramfs.img
As described above the cramfs.img is located in the ebrmain partition.
Since I was searching for it under linux the disk was mounted at /dev/media under the name "Volumn".
3.Unpack the cramfs.img (this could be done with cramfsck)
Command: cramfsck <image_name> -x <path_to_output_folder>
Example: cramfsck cramfs.img -x out
4.Modify the monitor.app
Note: monitor.app is located at: <path_to_unpacked_cramfs_image>/bin/monitor.app
I used ghex to modify the app by substituting the string "/sys/block/mmcblk%c/device/serial" with "/mnt/secure/.sd_original_serial".
5.Substitute the patched app 5.1: Copy the application to the mounted disk that contains the "pocketbook -> bin/monitor.app" symlink. 5.2: Rename the old symlink: Command: mv pocketbook pocketbook.ORG 5.3: Create the new link Command: sudo ln -s <name_of_patched_app> <name_of_symlink> Example: sudo ln -s patched-monitor.app pocketbook
6.Create the .sd_original_serial file:
Note: The .sd_original_serial should contain the CID of the original sd card;
To create the .sd_original_serial file i used the following command:
Command:cat /sys/block/mmcblk0/device/cid > ~/Desktop/.sd_original_serial
7.Copy the newly created .sd_original_serial to the "secure" sd card partion.
For me its name was a combination of 16bit code devided by "-".
8.Make sure both monitor.app and .sd_original_serial have the correct permissions.
Just to be safe i used: chmod 777 <name_of_file>
For both of the files when i copied them to their proper location.
I hope this helps you fix your device. Good luck
Hi

I need your help. On one of my PBTL3 I have internal memory problem. The PBL3 starts and operates normally but it does not save the setting changes and new apps etc.
I went thru the above mentioned procedures with the image from its original 4GB SD card and the image from the Russion site. Both did not work, resulting in the sand clock display.
I am not an expert with Linux but I installed Ubuntu on my Win10 PC and spent 5 days to go through the above instructions, learning terminal commands and how to root. I believe I can now execute all the steps correctly but the results are not successful after 5 days.

Because of this problem I bought the second PBTL3, which runs without any noticeable problem. I copied the image file from the 4GB SD card from this second PBTL3 to the 8GB SD, as the image is slightly larger than the 4GB SD from the first PBTL3, and went thru the above procedures. The result is the same; the first PBTL3 starts with this 8GB SD and shows the initial display but does not proceed further.

If I swap the original SD cards between these two PBTL3, their behaviors are also swapped.

I would appreciate it very much, if you could suggest what I can do further, as I am at a loss

Software version is: 0626 5. 8. 317.
I downloaded sw_20190730_U626_5.20.1157_user and flashed it from the external SD but it did not make any difference.

Thanks for your help in advance.

For this to work you need a firmware version lower than:
5.20.346
And no updates should be done afterwards, otherwise the sandclock doesn't go away.
or the permanent solution incl. possible updates:

Thanks for your quick reply. I have tried to use the image from this Russian site but it did not work. I have also downloaded the program files for generating .freezestatus file but have no idea how to use them due to my lack of Ubuntu experiences. Fortunately my PB3 works with the original 4GB SD with read only status problem. I was able to extract the device info using your app as attached.
I would appreciate it very much, if you could give me an instruction for generating the .freezestatus file;

Where in Ubuntu should I place the program.
What are the command lines I should execute in the terminal.

I learned lots about Linux for the last 7 days. This was not easy for 70 year old man.
Thanks for your help in advance.
