After I found out that Android 4.2 has the feature to create multiple users with their own profiles, I wanted to find a way to upgrade my Samsung Galaxy Tab 2/p5110 to Android 4.2.

I was a beginner in installing custom firmware (ROM) on Tab 2 and it took some evenings to finally have a shareable Tablet with multiple users. I want to share my progress and experience with you. So if you find something to improve please let me know.

If you don’t have already Android 4.2 and your vendor does not have an official firmware update (Stock ROM with Android 4.2 or later) then you need to install a custom ROM which is running Android 4.2. I choose a custom ROM from Cyanogenmod.org. Version CM 10.1 runs Android 4.2 and supports a lot of tablet devices (see).

This HOW TO is for Samsung Galaxy Tab 2 product family (also for Samsung Galaxy Note 10.1 see here). I worked out the HOW TO on my Tab 2 p5110.
Samsung Galaxy Tab 2 product family:
Samsung Galaxy Tab 2 7.0 (GSM) p3100
Samsung Galaxy Tab 2 7.0 (Wi-Fi) p3110
Samsung Galaxy Tab 2 7.0 (Wi-Fi+IR) p3113
Samsung Galaxy Tab 2 10.1 (GSM) p5100
Samsung Galaxy Tab 2 10.1 (Wi-Fi) p5110
Samsung Galaxy Tab 2 10.1(Wi-Fi+IR) p5113

But Cyanogenmod has installation instructions for any supported device, so you have to transfer some steps for other Tablets. The process to install a custom ROM can destroy your tablet device and is on your own risk. The installation of custom ROM is disruptive. You will lose all data and settings and you will start with a fresh installed Android 4.2 on your Tab 2. Please take time and read also the provided links to understand the general process and risks.

Select your Tab 2 device and read installation instructions from Cyanogenmod.org.

B- Put your Tab 2 in Download Mode
Quote:

Samsung devices come with a unique boot mode called Download Mode. If you put your Tab 2 in Download Mode then you can install a custom recovery with Odin. Rooting the stock ROM is neither recommended nor necessary.

1. Power off the Tab 2 and connect the USB adapter to the computer but not to the Tab 2.
2. Boot the Tab 2 into Download Mode by holding down the right volume button + power button. If the Tab 2 switches on you can release power button, but you still have to hold down the right volume button, till the device entered “Downloade Mode”. If you see the message “Downloading…” you can proceed with the next step
3. Connect USB cable and wait for Windows to detect the Tablet and the install the driver.

C- Use Odin to install custom recovery ClockworkMod

Quote:

ClockworkMod, abbreviated as CWM, is a popular custom recovery for Android tablets. ClockworkMod recovery allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the Samsung (stock ROM) recovery, and is one of the most common ways used to gain root access, back up device data, install custom ROM

1. Run Odin
2. Odin should now recognize your device and light up the ID:COM field yellow to signify this.
3. Click on PDA button, locate the downloaded GT-Pxxxx_ClockworkMod-Recovery_6.0.1.0.tar and click on OK to load it on Odin
4. Make sure that the “Re-Partition” and “Flash Lock” are unchecked; this is important as you might brick your device if these options are ticked!
5. Click on Start and wait for Tab 2 to reboot after Odin has completed.

The Tab 2 now has ClockworkMod Recovery installed.

D- Start ClockworkMod to Backup your Stock ROM

1. Power off the Tab 2 and insert an removable microSD Card (external sdcard)
2. Boot the Tab 2 into ClockworkMod menu by holding down the left volume button + power button. If the Tab 2 switches on you can release power button, but you still have to hold down the left volume button, till you see the ClockworkMod menu.
3. Use left or right volume button to select “backup and recovery” and press power button to enter “backup and recovery” menu
4. Use left or right volume button to select “backup to external sdcard” and press power button to start the backup. Wait for the message “backup complete!”.

Now you have an “image backup” of your Stock ROM. I recommend to backup to removable microSD card.
If you don’t have a microSD Card you can also backup to internal storage. To find/transfer see

E- Installing CyanogenMod (CM10.1) from ClockworkMod menu.

1. Power off the Tab 2
2. Put the CyanogenMod ROM .zip file and and Google Apps .zip file on the root of your external microSD card and insert it back to your Tab2. (I had to put cm-10.1-20130305-NIGHTLY-p5110.zip and gapps-jb-20130301-signed.zip)
3. Boot the Tab 2 into ClockworkMod menu by holding down the left volume button + power button. If the Tab 2 switches on you can release power button, but you still have to hold down the left volume button, till you see the ClockworkMod menu.
4. Use left or right volume button to select “wipe data/factory reset” and press power button to execute.
5. Use left or right volume button to select “install zip from sdcard” and press power button to enter install menu.
6. Use left or right volume button to select “choose zip from external sdcard” and press power button to browse microSD card.
7. Select the CyanogenMod .zip File and confirm with yes to install.

After CM10.1 is installed you have to install Google Apps.

8. Use left or right volume button to select “install zip from sdcard” and press power button to enter install menu.
9. Use left or right volume button to select “choose zip from external sdcard” and press power button to browse microSD card.
10. Select the Google Apps .zip File and confirm with yes to install.
11. Use left or right volume button to select “Go Back” and press power button to execute.
12. Use left or right volume button to select “reboot system now” and press power button to execute.
Now your Tab2 comes up with CM10.1 and Android 4.2.

F- Update Google Search and create User Profiles if needed

Use Google Play App to update Google Search (voice search should now work)
Create Users see

RESTORE- If you want to go back to your stock ROM

1. Power off the Tab 2 and insert the removable microSD Card (external sdcard) with the backup taken from step D
2. Boot the Tab 2 into ClockworkMod menu by holding down the left volume button + power button. If the Tab 2 switches on you can release power button, but you still have to hold down the left volume button, till you see the ClockworkMod menu.
3. Use left or right volume button to select “wipe data/factory reset” and press power button to execute.
4. Use left or right volume button to select “backup and recovery” and press power button to enter “backup and recovery” menu
