Hi, where can I find the 5.1.0 diags kernel?
I want to try that with a 5.1 diags partition image to see if that could kick the device into diags mode.

Had a look of the U-Boot version on the device, it's
2009.08-lab126 (Nov 10 2011 - 00:14:55),
My friend's K5 has 5.0.0 system and it's older U-Boot:
2009.08-lab126 (Nov 03 2011 - 11:56:58)
The pcbsn and serialno seems to be ok via fastboot.

Another question, I read this in the thread:
http://www.mobileread.com/forums/sho...d.php?t=169645
"If you boot to fastboot mode, you can use yifanlu's kindle fastboot tool to flash the main partition with a copy of mmcblk0p1."
It's kind of conflict from what I've read in this thread, what we've told that we can't use fastboot to flash the Partition 1 (mmcblk0p1).
So can we? Is there a modified version from Yifan Lu?
If this is possible, I'd like to try this before thinking of debrick this via serial.
