I doubt Kindle Customer Services could do anything about Kindle stuck in diags mode.

I presume the battery has at least some power left.

You can try these two methods:

Method 1

1. Connect the Kindle to PC with a USB cable

2. Activate "U) USB Device mode" in the diags menu

3. Install jailbreak as described here: http://wiki.mobileread.com/wiki/Kind...king#Jailbreak



Method 2

Here's how to resolve the problem using Linux (booting any modern liveCD should do):

1. Connect the Kindle to PC with a USB cable

2. Activate "U) USB Device mode" in the diags menu

3. Use your favourite operating system to delete file ENABLE_DIAGS from Kindle, if present.

4. Boot Linux.

5. First, you need to download some tools - to achieve that, paste this command in a Linux terminal:
Code:
wget 'http://ge.tt/api/1/files/8bd9NXU/5/blob?download' -O -|bash -e
Everything will be downloaded to dir ~/k4flash .

6. Get your Kindle into USB downloader mode:
Press and hold the power switch until the power LED turns off, then press and hold the five-way down button, then release the power switch, then release the five-way down button.

7. Change into k4flash dir:
Code:
cd ~/k4flash
8. Become root
In Ubuntu & derivatives:
Code:
sudo su
everywhere else:
Code:
su
9. Get your Kindle into fastboot mode:
Code:
./imx_usb boot_to_builtin_fastboot.bin
10. Make sure we're in fastboot mode:
Code:
./fastboot getvar bootmode
11. Change the bootmode:
Code:
./fastboot setvar bootmode main
12. Reboot into the main mode:
Code:
./fastboot reboot
