How to Update Sony Ericsson Xperia Neo with Official Cyanogen Mod 9 ICS Firmware

Xperia Neo LogoSony Ericsson Xperia Neo users can now benefit from the Official nightly build of ICS 4.0.3 firmware version powered by Cyanogen Mod Team. In the due course of this article we will be checking out a detailed coverage on how you can install this Cyanogen mod 9 firmware. Please note that this is the nightly build and may not be as stable as you expect it to be. Over a period of this article we will be checking out on what are the list of pre requisites you need to follow along with a detailed tutorial in the next page. This update which we will be discussing is not an Official firmware update released by SONY and also we don’t have any ETA on by when an official ICS update will arrive.

Disclaimer: Neither we, nor developer should be held responsible for any damage happened to your device in the process of following the instructions mentioned in this article. It’s very unlikely that there will be any issues but just in case if at all there are any issues then we are committed to help you in solving the same.

Note: This article should be only applied to the phones which are dubbed as SONY Ericsson Xperia Neo and not to any similar handsets. If this update is applied to any other phone then it may brick the device.

Rooting Information: Please be informed, once this procedure is applied the warranty will get void.  The only way with which you can reclaim the lost warranty is by re locking the boot loader again for which we will try to come up with an article on androidadvices.

Essential Pre Requisites:

  • All the data present in your SONY Ericsson Xperia Neo should be backed up so that just in case if any data is lost or corrupted, the same can be easily restored with the help of below mentioned steps. Don’t use any PC Suite to back up the data, as it will not recognize the device after the update since it’s a custom ROM firmware.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Disable all the antivirus suites in your computer and uninstall the same in your device as these tools generally tend to interrupt the process of firmware update.
  • Minimum charge left in the device should be at least 60% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
  • Enable the USB Debugging in your SONY Ericsson Xperia Neo from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked as shown in the below screen capture.

    It has been available in the UK mreakt for months and i got one as soon as it was released. So here are some tips after some time using the X1. Be patient as it may lack feedback in occasional cases, be careful when using the touch UI, because it is hardly thumb-optimized. Apart from this two little flaws, everything works just fine in the X1, i love it.
