Code:
zcat /mnt/us/rootfs.img.gz | dd of=/dev/mmcblk0p1 bs=4096
Kindle gave back this to my terminal on linux


Seems like this should have more warnings!

How can de-brick my kindle?
Still diags works and i am able to ssh to my kindle!

Can I retry it with bin files from 5.8.7?

Please help me out!

The 2GB firmware is known to brick the 4GB model.
I.E: It does not include the code to recognize the eMMC model used.
No memory == No run

Drop this idea before you waste a lot of time, producing a paperweight.

Let me try this just one more time -

Firmware for the PW2-2GB model will not run a PW2-4GB model.

Those of you who are hijacking my jailbreak thread for non-jailbreak problems, please stop.
