Hey dude~
I have Kindle 2i in hand, and the Software Version: Kindle 2.5.6(501108064);
After uninstall all of the hack, I try to update my K2i's firmware to 2.5.7_B003，it is no successful, get error code "U006";
And I found it is can't jailbreak either, the "kindle-jailbreak-0.4.N" is not work.

After "dumpMessages" I got the log info,
the error message is
"C def: patch: patchinfo="/usr/java/bin/cvm":checksum failure"

additional error info

install “2.5-jailbreak”
110108:135826 ota_install: C def: patch: patchinfo="/bin/busybox": patch failure

install “kindle-jailbreak-0.4.N”
110108:121453 ota_install: C def: patch: patchinfo="/etc/prettyversion.txt": patch failure

Could anybody help me to fix it?

(P.S. I have trid to uninstall the JB/Usbnetwork/Font hack/SS all version that I can find...what a pity... )
