The bootable USB didn't work even on an old laptop, but I have made a bootable CD and it works. Anyway it didn't repair my Kindle so I think that there is some problem with hardware.
I went through all the Kubrick procedure and got all the green lights. When it comes to flashing the main partition, which should take from 1 to 3 hours, it was done in several seconds and a message "Flashing done" appeared. After that it was not possible to start Kindle. It didn't respond.
Then I put it on charger and it was charging the battery for several hours. Then the charging LED was turned off without become green and after reconnecting the cable it becomes orange again and continue charging.
Something weird is happening.
It seems that even not being used Kindle runs some processes and drains the battery (or the new battery is also bad). The battery was fully charged two days ago, Kindle was not used, but still today it takes hours to recharge it. Sometimes happens that I try to turned it on and it turns on after 2 minutes, and starts with restarting. So it is doing something for that time which is not reflected on the screen.
Maybe power module is bad and interrupt the supply, which causes the frozen screen and often restarting.
I will try again tomorrow after charging the battery again. If it doesn't help it must be some hardware problem, so buy buy K3
Pocketbook InkPad will be my next choice
