Posted by techhackz-admin Thursday, March 11, 2010


Replacing your device radio can have many benefits including enhancing your battery life, phone coverage as well as GPS signal. Let’s take a look at how to replace your HTC Diamond 2 radio.

I won't be responsible if you end up bricking your phone, unlocking or flashing your radio or ROM can be risky. If you follow the instructions then you should be fine, I've flashed my phone several times without any problems!

Flashing your HTC Diamond 2 radio is very similar to flashing its ROM except that it will NOT hard reset your device so you'll NOT lose any data or programs you might have installed!

- HTC Topaz / HTC Diamond 2 or AT&T Pure.
- Hard-SPL package for your phone ( at
- your phone should be already configured with your computer and be able to sync with it through ActiveSync or Windows Mobile Device Center (Windows Vista or Windows 7)..

1. Unlock your phone
See my previous post about how to unlock your HTC Diamond 2:

2. Pick your radio
There are plenty of radios available for the HTC Diamond 2, you can find all of them @ XDA:

There is also a wiki site @ XDA that you can check out:

You will have to try a few of them to see which one works better for you, it depends on where you are located. Here is some feedback from the XDA thread (slightly edited to remove typos!): has received good feedback from Germany, Brazil, Hong Kong, Great Britain, Italy, Austria, Netherlands, India, Bulgaria, Singapore, France, China. got as well good feedback. I saw now difference on and it needs CID/Security unlock, because it comes from Rhodium. got some good feedback from Croatia. Some users report problems with Wi-Fi WPA. got good feedback from Europe, Japan, USA. This ROM is my recommendation!

3. Flash a new radio
When you have picked your radio of choice, simply download the radio and unzip the archive into a folder on your hard drive. If you get an exe file you don't need to unzip anything just double-click on the exe file to start the extraction process.

Once the files are extracted, you should see a CustomRUU.exe file, double-click on it to start the Radio flashing process. If you only get a NBH file then you will need to get the CustomRUU.exe file from a different release.

The process should take a few minutes, simply follow the instructions on your computer and device screen and wait for it to reboot.

That’s it you’re now all set!

You can test your newly installed radio using a tool created by akirius @ XDA, you can get it @
