Hello all,

I connected to my Kindle via serial port according to this schema https://www.mobileread.com/forums/sho...d.php?t=162775. I used
FT2303 based USB->RS232 adapter. Successfully, it is not support "real" RS232 (with negative signals), but it is very lucky for 1.8 TTL.

Now I may see that is happening with my device during the boot.

Below is my log of Serial connection to Kindle Touch:

It is still constantly rebooting...
because of two different events:
boot: I def:rbt:reset=user_reboot,version=000000:
crit system_monitor:job=network,sts=1,sig=:hard-reboot in 20 seconds:

What may I do with this?
And, by the way, for some reason, my keyboard is not working for Kindle. It ignores my "any key" before boot and my "enter" for maintenance menu.

Could you help me with this?
