Unbricking PW2 - erased eMMC

Hi All,

I'm trying to unbrick a PW2 (B0D4 - WiFi 2GB) with an erased eMMC.

I believe the kindle was stuck in a boot loop after installing an OTA update. USB drive was not showing.

Boot Log:

Wrong Image Format for bootm command
ERROR: can't get kernel image!
uboot >
Would someone be able to share the kernel/partition images. All links I can find are dead.

Thanks

Take the firmware version of your choice from the Amazon server.
Unpack the Amazon update package using our KindleTool utility.


PS: The above are two (very) FAQs.
Plenty of additional details available on-site here.

Thanks. I was under the impression that the updates wouldn't restore the diags partition?
