How to Update Samsung Galaxy S 4G T959V with Slim Bean ICS Firmware

Galaxy S 4G LogoSamsung Galaxy S 4G smartphone can now be easily updated with the latest Slim ICS firmware which is a custom ROM firmware. Please note that this is not an Official firmware released by Samsung Electronics and also there is no ETA on by when there will be an official update. Though this firmware says that it’s an ICS version of firmware but this firmware comes along with the Jellybean 4.1 features and also comes with a host of add-on applications which comes pre loaded in this device. Unfortunately, there won’t be any official firmware of jellybean 4.1 which will be released. Full credits to codedgraphx for developing this firmware.

Note: Please note that this update should only be applied on the devices which are named as the Samsung Galaxy S 4G, model number T959V. Unfortunately this update is not compatible with the T595 or with any other device.

Disclaimer: Follow all the instructions carefully mentioned in this article, we should not be held responsible in any manner if your Samsung Galaxy S 4G doesn’t boot up or gets bricked due to not following the instructions.

In the process of applying this update, all the data in your device will be wiped off, so with the help of below mentioned steps you will have to back up all the data using the below steps. Don’t use KIES or any other PC Suite tools for backing the data as it doesn’t detect the custom ROM firmwares.

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

All the antivirus tools in your device should be turned Off as these tools generally tend to interrupt the process of firmware update. Minimum battery life should not be less than 50% so as to make sure that just in case if the data gets lost or corrupted, the same can be easily restored. From Settings option you need to enable the USB Debugging option which is generally there in the Development options.

So now assuming that you have followed all the above mentioned instructions, you can now proceed to the next page where we have summed up a detailed guide on how to apply this firmware update.

    Could you possibly publish the Slim ICS for the T959W Canadian version? We just receive ‘Installation Aborted”
    Or lead me by hand to mofidy META-INF so that it allows it?
