Here we go. DISCLAIMER: you are on your own, so be careful.
Also, I tested this only on the original v1.6 firmware, but could (should?) run on the other versions.
Unzip the attached zip file somewhere in your M92 or SD card; you will find two directories,
gserial and
allow_root.
To login in your M92:- plug the usb cable;
- answer "No" to the USB Connection popup;
- run start_usb_serial.oar from the gserial directory;
- your computer should detect a new serial port device. Use you favourite terminal emulator to connect to it.
- login with user app, no password will be asked. (Be careful, even if you are not root, permission aren't really going to protect you.)
To logout press Control+D or type exit. If you want to login again, re-run the
start_usb_serial.oar command.
When you are done, logout then execute
stop_usb_serial.oar without disconnecting the USB cable. The usual popup will appear.
So now you want
to login as root, don't you?
Go to the
allow_root directory and run
root_pw_clear.oar; now you can login as
root, no password asked. To restore everything as it was, run
root_pw_restore.oar (will only work if you don't change the root password by hand, but if you can do that, I assume you can restore everything by yourself.) Also, does anybody knows what the original root password is?
Be careful and have fun!
EDIT: The archive was updated because I put the wrong module in there, as you can read below. Sorry guys!
