engineering hboot

Download the appropriate HBOOT for your phone:

T-Mobile G2: ​http://android.d3xt3r01.tk/cyanogen/vision/hboot/vision.hboot-0.76.2000.zip (md5sum 7669AE12DC2FAA10AE555A164980EFD0)

HTC Desire Z: ​http://android.d3xt3r01.tk/cyanogen/vision/hboot/vision.hboot-0.84.2000.zip (md5sum 2CE1BDD5E4C1119CCFCECB938710D742)

HTC Desire HD: ​http://android.d3xt3r01.tk/cyanogen/common/hboot/ace_glacier.hboot-0.85.2007.zip (md5sum df4fd77f44993eb05a4732210d2eddc6)

Note that the md5sums are for the actual hboot img contained within the zip file, not the for the zip file itself. Note also that the dz, g2, and dhd each use their own version of the engineering boot, as the phones are partitioned differently. (If you have previously installed the wrong HBOOT for your phone, you may need to reflash everything after partition 18)

Copy the files to the phone

Before you can adb as described below you need to enable debugging in the settings on the phone. In Settings go to "Applications -> Development" and check the "USB debugging" option.

In the commands to run below, $ or # represent the prompt and should NOT be entered as part of the commands (in Windows this will be something like C:\> instead).

Unpack all the zip files to a directory on your PC. Open a terminal or command window and change the current directory to where the files are on your PC and execute these commands:

$ adb push psneuter /data/local/tmp/
$ adb push gfree /data/local/tmp/
$ adb push busybox /data/local/tmp/
$ adb push hboot-eng.img /data/local/tmp/
$ adb push root /data/local/tmp/
$ adb push su /sdcard/
$ adb push Superuser.apk /sdcard/
$ adb shell chmod 755 /data/local/tmp/*

Temporary root

In the terminal (or command window) execute these commands:

$ adb shell /data/local/tmp/psneuter
$ adb shell

after the last command you should have a root shell in adb (this is indicated by a # prompt). Leave this terminal (or command window) that contains the root shell open.

S-OFF, Super-CID, SIM-unlock, engineering hboot and root

From now on we recommend to install the engineering hboot as part of the gfree procedure.

If you do not want to install the engineering hboot for any reason skip to the next section!

In the root shell (indicated by the #) that you got in the Temporary root section execute the following commands:

# cd /data/local/tmp
# ./gfree -f -b hboot-eng.img
# ./root
# sync

You may see an error message along the lines of "mkdir: /system/xbin already exists", but if so you can ignore that, the rest of the script should still run ok.

Wait a few seconds for the changes to "take".

Check the md5sums of the installed hboot

As it is very important that the hboot was installed correctly we recommend to check the md5sums of the partition. In the root shell (indicated by the #) that you got in the Temporary root section execute the following commands:

# cd /data/local/tmp
# ./busybox md5sum hboot-eng.img
# ./busybox md5sum /dev/block/mmcblk0p18

If the md5sums don't match then first of all - DON'T REBOOT and second run for help at the #G2ROOT IRC channel on freenode. If the md5sums match -> reboot your phone.

S-OFF, Super-CID, SIM-unlock and root

If you do not want to install the engineering hboot follow this steps!

If you ran the commands in the previous section the skip this section

In the root shell (indicated by the #) that you got in the Temporary root section execute the following commands:

# cd /data/local/tmp
# ./gfree -f
# ./root
# sync

You may see an error message along the lines of "mkdir: /system/xbin already exists", but if so you can ignore that, the rest of the script should still run ok.

Wait a few seconds for the changes to "take".

Reboot your phone.

Backup and cleanup

During the process gfree created backups of the partition that it changed to your sdcard in /sdcard/

The files are called /sdcard/part7backup-<time>.bin and part18backup-<time>.bin (if you installed hboot). It is highly recommended that you copy these files to a save location on your PC and keep them'''

You can delete the files in /data/local/tmp they are not needed anymore.
