[Desire HD Android Development] adroider:
hi all. I’ve been trying to unlock desire HD for a while and eventually managed to get it sorted.

The info was on this site, but scattered around a bit, so if this is useful (i.e. all in one place) let me know..

Like all these things:

IM NOT RESPONSIBLE IF YOU BRICK YOUR PHONE, AND YOU SHOULD ONLY DO THIS IF YOU KNOW WHAT YOU ARE DOING...!

IT WORKED FOR ME FIRST TIME. I DID THIS AS AN EDUCATIONAL EXERCISE ON A BRANDED ORANGE UK HTC DESIRE HD PHONE.

This was done with no sim card installed at any point, just a formatted SD card.

First do a factory reset of the phone with an SD card inside, no sim.

Start the phone, and go through the basic setup, by skipping most things, just so you can get to the home screen.

Step 1. Put your device in USB debug mode.

Press 'settings', then 'applications', press 'development', then tick 'usb debugging'

Step 2. Get visionary and install to the phone to do temproot, then permroot.

The apk file you need is com.modaco.visionaryplus.r.14.apk

I will try to upload, if the site lets me. Otherwise a quick search will find it.

Once it is installed to your phone (i used the htc desktop sync tool to install the app) by connecting my phone, select htc sync as the type of connection (as opposed to charge only) then from HTC sync suite (on your PC) select application installer, then select the visionary .apk file.

Once installed, disconnect the phone and power cycle the phone. (With all the power cycles mentioned in this post there is no 'holding of other keys' required)

Once back up, go into settings on the phone and you will see the visionary logo in your list of applications.

Start the application, and you will see the temp root option. Select this, and then come out of the application and power cycle your phone.

Once you do this, and the phone is back up again, go back into the visionary app, and then select permroot option.

Then again power cycle your phone. BTW, i did not select the tick box to make the folders r/w, some instructions said to do this.

Once you have restarted the phone for the second time, it should be perm rooted. To confirm its rooted, you can take the time to install a terminal program, and run an 'SU' command, but i did not bother. I just figured that the permroot worked.....which it did...

OK we are finished with visionary, thanks visionary guys..!

Step 3:

You need to get hold of the 'HD easy radio tool', again, i will try to upload the file.

Basically you need to unzip the zip file to a folder on your PC. Connect your HTC Desire HD, and then select 'charge only' in the phone selection. (i happened leave the HTC sync suite running on the PC, even though it was idle)

Go to the folder you unzipped on your pc and run the desire hd easy radio tool_V2_2.exe. you then get several options to choose. I went the whole way and selected the first option 'super CID,s-off, unlock'

Then proceeded to do it. It took about 30s to 1m. You should get a message that it was successful.

Thanks easy radio tool guys!!

Step 4.

You need a ROM, or RUU file. I chose this one. Its quite a large file and i will try to upload. I got it from this (xda) site, but cant find it now. From what i understand this one is completely 'blank' ie it does not appear to have lots of modifications, and it appears (from what i see on my phone) to be a clean factory rom. I tried to upload, but too big for site. You may need to google it.

RUU_Ace_HTC_WWE_1.72.405.3_R_Radio_12.28e.60.140f_26.04.02.17_M2_release_161342_signed.exe

Connect your phone (again in charge only mode) and then start the 'RUU_Ace....' application on your PC.

It will start an HTC installer application that will try to connect to your phone. It will then show the current ROM you have installed, and confirm that you want to update to the one shown.

Remember to have a good charge in your battery, and don't disconnect during this point, you will brick your phone if you do. Make sure your PC does not go to sleep, and have it on external power if its laptop.

The flashing process takes about 2-5 minutes.

Once complete the pc htc application will tell you all was good.

The phone needs to be rebooted, if it has not done so already, and when it starts up, the phone will be brand new. No orange logos, no orange s/w, and fully unlocked to use any SIM card.

Good luck!
