It was the last time when we reported about the arrival of Gingerbread 2.3 firmware officially via KIES Mini, but in the due course of this article we will be checking on how you can power up your device with the unofficial ICS Android 4.0.3 firmware. Please note that this update is not officially rolled out by Samsung Electronics and also there is no ETA on by when Samsung will ever bring ICS update officially. In the process of applying this firmware, you need to ensure that your phone is rooted as this procedure can only be applied on the rooted phones. Though there will be some bugs but we are pretty sure that developer will soon come out with the next version which will come up with enhancements.
Advisory: This update should not be applied to the phones which are NETWORK LOCKED DEVICES, if you still continue to update your phone then we cannot guarantee on the consequences. This should be applied only to the model I897 and not on any other I9000 models.
Disclaimer: Please be informed that this process involves the rooting of the device and once the device is rooted, the warranty gets void. The only way with which you can restore back the lost warranty is by re installing the stock firmware in your phone. We will try our level best to come up with an article with the factory firmware.
Important : First thing is you should back up most of the things on your phone. You should back contacts, third party applications, text messages, Phone contacts, pictures and other music video files can be backup to internal and external SD card. Make use of the following dedicated apps –
SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Notes – Manually save the notes in your mail as these will be lost in the process of firmware update
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”
Minimum battery charge left in the phone should be at least 70% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
