My kindle is brick for installing process of cm10.1. so i enter the fastboot mode and use this tool .
but after restore su & reboot , amazon logo (yellow colored kindle fire) appear and stopped
how do i fix it? please help me
using the cm10 process means that you have loaded a custom recovery. That means you need to flash the original recovery system back to the device. I believe verygreen explains this in his post on the cm10 build. You could use this tool but you would have to use the downgrade method explained in the op.
