Unable to ROOT Desire Z from 2.2.1?

[AlecTaylor]

I want to load a custom ROM on my Desire Z. (finally!)

And I eventually got adb to work.

Now following the guide: Rooting the Vision (G2/DZ) and DHD; I got as far as this step:

4 S-OFF, root and its friends Super-CID, SIM-unlock, engineering hboot, clockwork recovery and root

In the following section we are trying to gain write access to the emmc by power cycling it.

We recommend to install the engineering hboot as part of the gfree procedure.

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 -y recovery.img
# ./root_psn
# sync

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

Before receiving this error:

# ./gfree -f -b hboot-eng.img -y recovery.img
./gfree -f -b hboot-eng.img -y recovery.img
--secu_flag off set
--cid set. CID will be changed to: 11111111
--sim_unlock. SIMLOCK will be removed
--hboot set. hboot image hboot-eng.img will be installed in partition 18
--recovery set. recovery image recovery.img will be installed in partition 21

md5sum #3 == md5sum #1 - the hboot image was not installed!
Probably the power cycle of the eMMC failed. Check the messages above.
You might join the IRC channel #G2Root on Freenode for further help!

What should be my next course of action?

Thanks for all suggestions,

Alec Taylor

Double check you have the right hboot downloaded and that the md5sum matches, then run the command again. If you still have issues copy and paste your input/output from cmd here

I have included the input/output from my CMD in the initial post.

Sorry I thought you were just copying and pasting from the guide you were folowing. I guess I was reffuring to the entire root procedure but its no big deal
Its telling you exactly what is happening, phone didn't take the flash of the new engineeging bootloader, probably the emmc didn't cycle, try running command again, if its the same outcome double check your radio version as that can cause this or can you post all info from your hboot screen here

Also I couldn't get it to work with Gingerbreak or DooMLoRD's Easy Rooting Toolkit either.

Right down all info on boot loader, you seem to know what to do but you're missing something, possibly need to change radio as gfree will not work with newer ones

FYI: Was able to root it finally by upgrading my stock to gingerbread from froyo; then back down to non-stock froyo followed by upgrade to modded Jelly Bean.
