Hostar & Geekmaster - thnx for help and quick reply!
I try your advice - here is all procedure:
First - I started MfgTool and connected kindle (using magic button to enter in Diags mode).
D) Exit, Reboot or Disable Diags
then F)Fastboot Bundle Install.
After that i started inf-wizard.exe and make "Kindle.inf" file.
This time VID/PID was 1949/D0D0.
Then - open cmd and start fastboot.exe:
fastboot getvar serial
- getvar:serial FAILED (command write failed (No error))
finished. total time: 0.000s
So, i tryed to install geekmasters inf file. I just copy that file into my generated "kindle.inf" file. Installed new inf file, and started fastboot again - same result.
I'm sure I'm so close to the right answer..... can't figure out where is mistake.
kindle fastboot inf installed....
VID/PID is 1949/D0D0...
Geekmaster: thnx fot avatar idea!
