PW3 Need Help! Navigate the Diag mode over Serial console

Dra_w · 12-25-2020, 12:36 PM

Hi. During doing some research on the Diag mode of Kindle Paperwhite 3, I try to test the MAD TEST under the Mics Individual diagnostics menu which laterly corrupts the touch driver, unfortunately.

When I try to re access this test mode with my touchscreen not responsible to figure out what happended via serial console as below, I cannot access by typing 'o':
diag> MUSCAT_WFO - System Diags - 100

Code:

   ~~~~  1.1.40.329941  ~~~~
     pcbId:0670709182970F82
(DS INFO)-Device Setting
(TOUCH PLATE)-Touch Plate Test
(OTS)-Operator test suite
(o)-Misc individual diagnostics
(WIFI NART)-nART factory test
(USB EXPORT)-USB device mode
(o)-Reboot or Disable Diags
(POWER SUSPEND)-Lock screen
(X)-Exit
diag>   O: command not found!

Does anyone know how to access the Mics individual diagnostics menu or how to fix the touch firmware corruption as information below:

Code:

ds info
get_input_from_stdin Received [DS INFO]
diag>   MUSCAT_WFO - DS INFO -  51

Look at the main startup scripts, some of 'em are responsible for flashing the blob.

(Some of that may or may not be hidden behind a feature flag, not that it's relevant since you're probably going to be doing it by hand anyway).
