Hello,

My Kindle PW2 stopped booting for some reason and tricks like reboot, hard reset, connecting to PC, charging etc. did not help. So I tried to re-flash it using TTL converter and soldering, but I got an issue when I was following the manuals. When I type bist in Putty, it goes into bist mode, but then I type fastboot and it hangs. By hangs I mean that it does not show any messages except battery voltage (so no Connected or USB speed HIGH messages). But more interesting, that if I connect both TTL converter and USB cable to my Kindle and PC, I get the successfull connection, but for 10 seconds only (then it goes back to bist automaticaly). Tried this on Windows and Ubuntu - result the same.

Could you point me, what can be the reason of such behaviour, please?

Appreciate your help!

Best regards,
Egor.
