How to Update HTC Desire Z with Jelly Bean CM10 Custom ROM

Furthermore, now there are suitable updates available for almost all the Android powered smartphones out there, so it’s really hard to stay calm and wait for the official update to come. Anyway, today it’s time for another handset to receive the Jelly Bean flavor as the HTC Desire Z can be easily updated by learning how to install the CyanogenMod 10 Custom ROM firmware into its system.
So far, CyanogenMod 10 is the only Android 4.1 based custom ROM available, the software being already delivered for several devices such as HTC Evo 4G, Samsung Galaxy S2, HTC One S, HTC Sensation, HTC HD2, Galaxy Vibrant and more. You can learn how to update the mentioned smartphones by checking our latest step by step guides. But, there is one big inconvenience with these updates: the CM 10 firmware isn’t official yet, so we are not dealing with a stable version of the same.

For example, for the HTC Desire Z, you will have problems while trying to use the WiFi, Data / Network, sounds, music player and much more. As the ROM is not official, the beta version is being offered and tested by those of xda-developers who had tried to bring a relatively runnable OS. Don’t worry though, as the bugs will be resolved and removed once the CM team will release the software, updating with the same being more than easy. But, let’s see which the features that do work are, as this is the most relevant aspect:
Now, the HTC Desire Z is a low range smartphone with poor specs. The phone is coming with an 800 MHz processor, 512 MB of RAM and a 5 MP camera. Gingerbread is on top of all, so as you can see an update is more than welcomed. The CyanogenMod 10 ROM will bring Jelly Bean to you along with many other capabilities that will power up the performances of your phone. The battery life will be improved, the system unchained and opened for changes, you will gain more speed and you will be able to get apps from outside the Google Play Store coverage.

- After rooting, you must install a custom recovery image on your Desire Z.
