Tested and confirmed to work with Kindle 2.
Firmware: Kindle 2.5.8 (555370010)
Create an empty file named
ENABLE_DIAGS in the root folder of the mounted Kindle volume. Unplug the Kindle and give it a full power cycle (reboot).
It should not have a ".txt" extension, so if you are using Windows make sure that you uncheck Hide Known Extensions in your folder options settings.
P.S. MoviNand tests are non-destructive. They just verify the filesystem.
Code:
MoviNand RootFS Verification
----------------------------
FAILURE
The rootfs failed md5sum verification
beause the following file had a bad md5sum:
/usr/lib/tts/speech/components/voicefont/vf_tom_fu ...
FS Version : 010-TNM0.9-055537
Build Date : Thu Jan 13 18:17:49 PST 2011
Press X to continue ...
Note, this device was never hacked, only firmware updated once. This gives me the impression that one shouldn't worry about a receiving a similar test failure.
