Radio S-OFF

WORK IN PROGRESS NOT DONE YET And scotty2 did it again!

Howto (Overview of the steps)

  1. Perm root your phone
  1. Make a backup of partition 7 of your phone
  1. Use a custom kernel and the appropriate wp-this module to get rid of the write protection of the radio partitions
  1. Copy the image of partition 7 to your PC and modify it with a HEX-editor, push it back to phone and copy it to the partition 7

At this point in time the @secu_flag is removed from your phone and you can run certain AT@SIMLOCK commands.

  1. start hboot, attach a serial console to it and start rtask c
  1. attach a serial console to the now running AT-command interpreter and run AT@SIMLOCK=3,2 to write the subsidy data clear text to partition 7

4 Enable @secu_flag=0 in partition 7

adb push mmcblk0p7-new.img /sdcard/
insmod /sdcard/wpthis-cyanogen.ko
dd if=/sdcard/mmcblk0p7-new.img of=/dev/block/mmcblk0p7
sync

Wait a minute to make sure that the changes stick

5 start rtask c in hboot

sudo modprobe -r usbserial
sudo modprobe usbserial vendor=0x0BB4 product=0x0C94
sudo screen /dev/ttyUSB0
rtask c

This will terminate your console session. Attach the serial to the new USB-device

sudo modprobe -r usbserial
sudo modprobe usbserial vendor=0x05c6 product=0x9002
sudo screen /dev/ttyUSB2

In the following code there is mixed commands and answers. You only type the commands the start with AT.
