Attempted serial jailbreak but the diagnostic menu is different?!
I hooked up my KT2 (serial begins 90C6, firmware ver. 5.8.9.2) using a USB serial and I can get to the uboot> prompt.
I enter Code:
bootm 0xE41000 So I started pressing buttons. Entering a ? gives the text output below. Entering d, l, m, o just gives the same error. Code:
BOURBON_WFO_PREEVT2 - System Diags - 82 ~~~~ 1.16.614.246981 ~~~~ pcbId:0620601144260BGF (DS INFO)-Device Setting (OTS)-Operator test suite (o)-Misc individual diagnostics (WIFI NART)-nART factory test (USB EXPORT)-USB device mode (NEONODE DRAW)-Touch Draw test (o)-Reboot or Disable Diags (POWER SUSPEND)-Lock screen (X)-Exit m get_input_from_stdin Received [M] TCP_IP_Server_Handler:exe pass in null menu item! d get_input_from_stdin Received [D] TCP_IP_Server_Handler:exe pass in null menu item!

Nevermind. I was using the kindle face down and only looking at my serial terminal. (Since there was some delicate soldering on the back, I was reluctant to move it around.) Flipping it over, I found a menu which allowed me to quit the diagnostics and get to the login prompt.
Everything else wen pretty much according to the guide; got rid of the root password, ran the jb.sh script, and KUAL works! btw, I used a sparkfun-branded 3V3 FDTI USB serial converter with a Sparkfun bidirectional level shifter. (I got the 1.8V for the low side of the shifter from an Adafruit adjustable breadboard power supply.) I'm not a huge fanboy of Sparkfun, just had this stuff already and wanted to make use of what I already had. |
