Help jailbreaking Kindle DX on 2.5.8 (555370010)

golliher · 05-18-2026, 08:34 PM

I have spent the afternoon trying to jailbreak my Kindle DX.

Suspecting the problem was with the date, I create a .bin file that has set it to Jan 1, 2025.

However when I try to update using Update_jailbreak_0.13.N_dx_install.bin
I get update filed and there is no "You are Jailbroken book" and ";log" does nothing.

I tried repacking it to add logging to see where it is failing, but from here I'm lost. It seems the jailbreak file I have doesn't match the firmware on my Kindle DX (serial starts with B004)

I would love some help with this. I feel like I'm close, but also I'm stumped.

Thanks for the reply. Unfortunately, for the original Kindle DX the guide at kindlemodding.org does not work. I have used it for several newer Kindles, but not for the original Kindle DX (ID 0004)

I did however eventually find this thread and it got me to a working KUAL and KOREADER

Case closed. :-)
