We are going to install ClockworkMod Recovery on the Galaxy Tab 2 10.1 (GT-P5100 is also valid for GT-P5110) with heimdall. After that you can root your stock image or install CyanogenMod on your tab. If you have another version of Galaxy Tab 2 you will need other images for it, for links take a look at the links at the bottom.

Warning: It was working for me. I’m not responsible if you break your device. You are doing this steps at your own risk. The installation of a modified firmware invalidates the manufacturer’s warranty! You have been warned!

Flashing recovery

What we need:

• Heimdall v.1.3.1
• Recovery image (Odin package)

Lets go

• Install heimdall, in ubuntu you can install vía apt: sudo apt install heimdall
• Unpack the tar Recovery image
• Disconnect your tab from PC and shut it down
• Press Power+Volume Up
• Confirm the warning dialog with Volume Down
• Connect the tab to PC
• Flash the recovery (please start heimdall with root rights to avoid any access problems)

sudo heimdall flash --RECOVERY image-twrp-x.x.x-p51XX.img --no-reboot

• Disconnect your tab
• You can boot to recovery if our press Power+Volume Down, release power button when you see Galaxy Tab logo and hold Volume Down for the next 5 seconds. Wait for recovery, it takes some time.
• You can now proceed with rooting of stock image or with installing of CyanogenMod

Rooting stock image

What we need:

• Root installation with Recovery Clockwork zip package.

Lets go

• Upload the CWM (Recovery Clockwork) package to sdcard (yes, to the external microSD)
• Boot to recovery and select “install the zip”
• Select CWM zip package, that’s all

Flashing ROM with Google Apps

What we need:

• ROM image for the tablet. In this link, https://andi34.github.io/roms_tab2_lineage.html, you can see the different options, one that has worked very well for me has been LineageOS.
• Download the Google Apps for the version of your ROM in https://opengapps.org/
• If Google Apps doesn’t work you can install Aurora Store as an alternative, in https://f-droid.org/es/packages/com.aurora.store/

Lets go

• Upload the both zip files to the external sdcard
• Boot to recovery and install the zips
• Do a “wipe data / factory reset”
• Reboot
