I booted to the TWRP recovery for the first tiem and played with it by wipping everything using all the wipe options. Then I ended up unable to boot to the fastboot mode, normal mode or recovery mode.

And here is the message I got:

exec '/system/bin/sh' failed: No such file or directory

I read that I only have two options to boot to the fastboot mode: 1- Factory cable. 2- Opening the case and using the motherboard.

Is there a new way other than these last options?

If you have one of the custom bootloaders then you don't need either of those methods to get into fastboot; it will automatically listen for fastboot commands for 5 seconds at the beginning of the boot sequence. How did you install TWRP? – eldarerathis Oct 30 '12 at 13:51
I used Kindle Fire Utility from XDA Devs. – MIH1406 Oct 30 '12 at 23:04
