Original software
A regular sdcard is used as internal memory, so we can simply take it out and read/write it on the computer. It is worth noting that the image is tied to a specific sdcard (its serial number), but it is enough to simply untie the image from this dependence.
Note: Before experiments, make a backup copy of the SD card (via dd) |
# fdisk -l /dev/sda
Unlinking an image from a specific SD card: after the system starts, the main application is launched - pocketbook located in /dev/sda8 (in fact, this is a link to /mnt/cramfs/bin/monitor.app). This binary contains a check for the serial number of the memory card. However, we can easily cheat this check: replace the path to the serialnumber of sdcard with a simple text file with this number.
copy the cramfs.img file from sda8 and unpack it: cramfsck -x tmp_cram cramfs.img
As a result, there will be a monitor.app file in the tmp_cram/bin directory.
Using strings we can find that the program gets the serial number from /sys/block/mmcblk%c/device/serial
Сreate a file with serial number in /mnt/secure (you can do it in another place, the main thing is that the final path is the same length as the line above) and replace path from from /sys/block/mmcblk%c/device/serial
to your file.
now just copy the file to sda8, delete the old link and create a new one. ln -s monitor_patched.app pocketbook
