Hi,
I am so happy I could leave the freezed screen (now I know that Kindle was in fastboot Mode).
I followed the steps in this forum:
fastboot for win32
https://www.mobileread.com/forums/sho...d.php?t=171460,
except that in the steps (written by Poetcop) I omit running step
fastboot flash diags mmcblk0p2_ssh.img [from the first post in this thread]
because I thought that the partition was Safe.
Following the capture of the Console in Windows XP
C:\kindle\fastboot_win_public>fastboot setvar bootmode diags
setting 'bootmode' to 'diags'...
bootmode diags:
finished. total time: 0.016s
C:\kindle\fastboot_win_public>fastboot reboot
rebooting...
finished. total time: 0.000s
Thank you very much to all the experts in this forum for sharing priceless information for the benefits of all.
Good luck!
