Even though there are only few custom ROMs available for the Samsung Galaxy Tab 2 10.1 model number P5110, you can still improve and optimize the performances and the looks of your tablet by installing the new Blackbean firmware. Also, by flashing the software you will be able to update your Tab 2 10.1 to latest Android 4.2.1 Jelly Bean OS, though you will actually get a custom (different from the default Android system) Jelly Bean flavor. You have it all explained during the next few lines, so if you want to try something new for your Tab, then complete the present step by step guide.
This version of the update is still in development stage, but according to our sources (those of xda-developers) you have nothing to worry about because there are only minor bugs in the system and the same will be resolved soon. Also, we are dealing with the unofficial variant of the Blackbean platform, meaning that third party devs worked on providing the software. As mentioned there might still be some issues in the ROM, but you can safely download and install the Blackbean Jelly Bean 4.2.1 OS on your Galaxy Tab 2 10.1 for a daily use.
The update is based on the AOKP and CM10 ROMs therefore you will be able to flash important features and new apps on your Galaxy Tab 2. Remember that the firmware brings the Jelly Bean 4.2.1 system on your Tab 2 10.1, but you will not get the default Android looks as the Blackbean OS is a custom ROM and not an official software. Now if you want to read more about this update, about its bugs and features, check the link from here. Then return and resume the rest of the steps from this tutorial and in the end you will safely manage to update your Samsung Galaxy Tab 2 10.1 with the Blackbean custom ROM.
Before heading to more complex stuffs, here is what you have to do: root your tablet or else you won’t be able to apply the firmware and update to Jelly Bean 4.2.1; then install a custom recovery image on your device, this being the tool that will be used on the update process; backup the data (contacts, text messages, market apps, EFS and so on) and make a Nandroid backup before starting the flashing operation because a full wipe of the system will have to be performed.
Completing this guide and the root task implies in voiding the warranty. This is happening each time you want to perform unofficial operations, but don’t worry as if you are following dedicated tutorials everything will be fine. Furthermore, the warranty can be easily restored as soon as you downgrade the Galaxy tab 2 10.1 to stock ROM, or when you update the device with an official software released by Samsung. Of course by doing the mentioned things, the root access will be revoked, the bootloader relocked and the factory restrictions reinstalled, but at least you will have the warranty back.
Now, all you have to do is to ensure that you can use a computer or notebook with internet connection enabled and you can start the update operation. Also, the tablet and its USB cable should be near you; the USB debugging option on your Galaxy Tab 2 should be checked; there shouldn’t be any security programs running on your computer or handset as these programs will interfere with our work; the device should have enough battery power (at least 60%) or else you should charge it; and you must apply the next steps only if you want to update the Samsung Galaxy Tab 2 10.1 model number P5110 to Android 4.2.1 Jelly Bean with the CM10 and AOKP based Blackbean custom ROM firmware.
