motorola-defy

Thanks to the xda-developers, the Motorola Defy users can now receive the Android 4.0 Ice Cream Sandwich OS update. The update can be achieved by installing the CyanogenMod 9 custom ROM on your phone’s internal system. The operation is not hard to complete, but in order to do it right I recommend you to follow this how to guide. If you do it by your own, without consulting us, you might wreck your handset and I know you don’t want that to happen; so take a look below and learn how to safely update your Motorola Defy by installing the CyanogenMod 9 ICS 4.0.3 Firmware.

Also, read the whole tutorial in order to avoid the unpleasant situations. There are some things to consider and some preparation processes to complete before starting the proper guide; without these operation you can lose the data stored on your phone, or worst, you can damage its Android based system. Don’t worry, as you have it all detailed and explained so everybody can understand what to do. We should be done in just a couple of minutes, so let’s get started.

CyanogenMod is a firmware that comes with many features that aren’t included in a basic version of the Android platform. But, the only way in which you can enjoy these advantages is by flashing the same on your device. In a few words, CM is a free aftermarket distribution of the Android platform and you can take advantage of it without having any particular Google apps installed because it’s developed on the Android Open Source Project. A specialized team is working so CM can be installed on almost every Android powered devices, so we have them to thanks.

I know that the Motorola Defy is not a high end smartphone, but the CM 9 ROM will manage to improve its performances. Its system will be unchained from the factory restrictions and several features and capabilities will be added. You will be able to customize and optimize the operating system, the appearance and many other things by your own taste, making your phone your new playground. Furthermore, you don’t have to buy a new handset in order to enjoy the new Ice Cream Sandwich OS as it will run perfectly on your old Defy as well.

But, unfortunately, there are some negative aspects too. The most relevant one is that installing the CyanogenMod 9 ICS 4.0.3 firmware will make you void the Motorola warranty. In case if something bad happens (this may occur extremely rarely and only if you don’t follow our directions) you will be on your own. Then, in order to succeed, you must first root the Motorola Defy. The update can’t be applied on an un-rooted device.

Then, the release of this OS update isn’t coming from Motorola and it has nothing to do with the mentioned company. Unfortunately, there are no words about the possible launch of the ICS firmware, so this may be the only method for getting it. Also, CyanogenMod 9 is still on the beta version, meaning that it isn’t finished; there might be some bugs in the system. But, these issues should be resolved as soon as a new update will be released by the CyanogenMod developers.

Now, as I already mentioned above, there are some preparation things you need to take care of. During the installation process you need to use a Windows / Linus / MAC running computer, the phone and its USB cord. Prepare the handset and the PC as showed below:

  • Applying the update might wipe the data out from your Defy. So, in order to keep your personal info in safe hands I recommend you to backup the Motorola data, contacts, messages, calendar ans apps.For making a safe backup, I suggest to take a look over a guide like this one; you can always check our latest tutorial for learning how to download SMS backup and restore app for Android.
  • Enable the USB debugging in the smartphone. Simply go to “Settings -> Applications -> Development -> USB debugging”. Disconnect the device from the PC when trying to enable the USB debugging.
  • The power form your handset should be around 60%; if not charge the Defy.
  • It will be a good idea to deactivate the antivirus tools from both PC and smartphone.You can re-activate them as soon as the ROM is applied.

You can now go to the second section of the post and the one that interest you the most:
