some time ago, I used an automatic flasher to install the OS on internal memory card of my n810. Since then, every time I restarted the device I had to hold Menu and choose the partition from which I wanted to boot (now I learned I could change that using bootmenu file or something similar, but that is not the problem).
The problem I have now is, that I updated my OS2008 with the Application manager. I backed up my using the automated procedure. And now I don't see the boot menu anymore, so the device boots up to old OS.
Are you sure to continue? (yes/no) : y
Create backup of current initfs (yes/no) : n
Part 1 - Preparing initfs.bootmenu.jffs2 image
*** copying current initfs ...mount: mounting /dev/mtdblock3 on mnt failed
If you remove extra stuff you may write to initfs and customize bootmenu.
Remove unneeded extra (and factory testing) stuff? (yes/no) : n
!!! unknown initfs version 2008-43, cannot install bootmenu
Cannot find initfs.bootmenu.jffs2, something failed, nothing flashed.
I tried redownloading the initfs_flasher, reextracting, doing it with other options but nothing quite helps.
I would greatly appreciate it, if you would help me
