edit : crap ..... worng section ... how do I delete ?

Hello.

I have a KFHD 7" happily running under Hashcode's CM10.0. I'd like to update to kitkat.
For that, it seems I need to upgrade my recovery from TWRP 2.4 to 2.7. ( If the rom should install under TWRP 2.4, let me know, cause I got an error when I tried. )

So, after messing a bit with my drivers, I got ADB to work fine.

However, I need fastboot to update recovery. My Kindle can go into fastboot, no problem.

But windows just won't recognise it. "Fastboot devices" always show no devices connected.

I tried with various drivers ( including those from QEMU thread ) on 2 differents computers.

So I'm starting to wonder if there is something I missed in the virious threads. Is there something I should know that would prevent me from seing the device under fastboot but not ADB ?

Are you running Windows 8.1?

If you have the image,try using FireFlash by stanga72. Just place the image on the sdcard,open fireflash,select "Flash Recovery" and choose the image. Hit Flash,and reboot into recovery.

For some reason, Kindle devices won't be recognized in fastboot without the specific flag "-i 0x1949". For example, "fastboot devices" becomes "fastboot -i 0x1949 devices" and "fastboot flash recovery recovery.img" becomes "fastboot -i 0x1949 flash recovery recovery.img".
I'm positive this is the issue.
Have a nice day! :D
