This is a global release and the same can be applied to all the Neo V devices, only thing which you need to ensure is that it should not be applied on the network locked phones.

Pre Requisites:

  • All the data like SMS, Contacts, Call log, APN, MMS Settings and other data present in your internal SD should be backed up so that just in case if the data gets erased or corrupted, the same can be restored with the help of below mentioned steps. Remove the SIM card as well as SD Card from your phone as it’s recommended to remove the same.

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 Arc S from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked as shown in the below screen capture.

USB Debugging

  • Just in case if you are on any of the custom ROM firmware, then you need to clear the cache and wipe the data from the recovery mode. Also, additionally if there are any lag fixes, you need to disable the same or else it will hamper the process of firmware update.

As soon as you follow all the instructions, you can now proceed to the next page where we have mentioned a detailed article on how to apply this firmware update.

  38. Couldn’t update . Error block sin that’s what it’s says

  39. Hey guys, I have successfully upgraded my Xperia Neo V to ICS 4.0. The new looks and features are cool. But you never warned that this update will wipe out my phone’s data. I must say that Google has done an amazing job in restoring my apps and data.

    For Android Devices, please note that your instructions are incomplete and misses some disclaimers. Also, as given in the instructions that after upgrade phone will reboot automatically, it actually didn’t. I had to manually boot the device after waiting for 10-15 mins.

    Nevertheless, it was a job well done and I have got my long expected ICS upgrade. Thanks folks.
