The T-Mobile users of the Galaxy Tab 7.7 can now receive the official Ice Cream Sandwich 4.0.4 update as the ROM has just been released by Samsung. The OS can be OTA (Over The Air) applied, but for those who prefer to install the firmware manually, I have develop the present step by step guide. Also, this tutorial will be perfect for those who want to downgrade the Tab to the stock ROM for regaining the warranty, or to restore the official Android system if they recently flashed a custom ROM that isn’t performing as it should. Regardless the reasons, during the following lines we will be checking in how to update the T-Mobile Galaxy Tab 7.7 to official ICS, so for the proper procedure, check it out.
Remember that this is a manual method so you will not use the Samsung KIES for applying the ROM. Furthermore, you will have to complete a more complex operation which implies in downloading, installing and then using the Odin tool. Anyway, we will discuss more about this during the proper steps. KIES should be installed on your computer though as it brings the latest drivers available for your device and we will need them for succeeding with our purpose. For those who don’t know Odin is designed especially for this type of operations, so you have nothing to worry about; the program will only ease your work.
As we are dealing with the official Ice Cream Sandwich 4.0.4 update which is released and provided by Samsung just for the T-Mobile Galaxy Tab 7.7 model number T859, by applying the same on your tablet you will not void its warranty. More, for being able to perform this manual operation you don’t have to previously root your device. If the tablet is rooted, you will then revoke the root access, the factory restrictions being reinstalled. So, you will have to regain the root access but only by following a tutorial that suits the new OS. That’s why this update is perfect for those who want to downgrade the Galaxy Tab 7.7 to the stock ROM as the warranty will be restored and the bootloader relocked. Finally, you don’t have to install a custom recovery image for this process as Odin is all that you need.
The only thing that you must take care of is referring to the data which is saved on your tablet’s internal storage memory. The info might get corrupted so you will not be able to use it once the update is installed. Therefore, it is more than recommended to backup the Galaxy Tab 7.7 first. There are many ways available for performing this operation, but choose the one that you prefer the most. You can anytime download and use free distributed backup and restore apps from Google Play store, save files to a computer or SD card or use the Android cloud by syncing with Google. More info about these processes can be found by searching through our how to section; you will find there all the details needed for completing a full and safe backup.
As soon as the backup is completed, you must ensure that you can use a Windows running computer with Internet connection enabled, your Galaxy Tab 7.7 and its USB cord. For being able to apply the update without any headaches I recommend you to deactivate the security tools (antivirus, Firewall, and so on) from both computer and tablet. Then, as you will connect the handset with the PC, the USB debugging option from your Tab must be enabled. Remember to install the KIES for getting the proper drivers. And if your device has less than 70% battery power left, use the charger and plug it in for a while.
The official ICS update will power up the performances of your T-Mobile Galaxy Tab 7.7 by adding new features and capabilities into the system. Also the battery life will get improved and some previously reported bugs will be removed, so you will be able to enjoy a more stable and smooth operating system. Be aware though, as this how to guide is being suitable only for the Galaxy Tab 7.7 model number T859; don’t apply the steps for similar devices as you can easily brick them. In order to check the version number of your tablet go to “Settings > About Device / About Tablet”.
