The CyanogenMod 9 (CM9) ROM is now official for the Samsung Galaxy Tab 10.1 (3G version). For the uninitiated, CM9 is an AOSP based ROM based on Ice Cream Sandwich Android 4.0 that features faster performance than stock ROMs, as well as a high amount of customization options, along with an inbuilt themes engine. It also comes without any unnecessary OEM apps and bloatware.
CM9 is in the nightlies stage and still under development, so some things may or may not work correctly. Nightlies are ROMs that are built automatically every night, incorporating the latest changes made by the developers, which makes sure it is always up to date. However, since nightlies are automatic, they can introduce untested bugs and issues.
Let’s take a look at how CM9 can be installed on the Galaxy Tab 10.1 3G P7500.
This firmware and the guide below are compatible only and only with Galaxy Tab 10.1 3G, model number P7500. It’s not compatible with other Galaxy Tab 10.1 variants or with any other device. Check your device’s model number in: Settings » About tablet.

How to Install CM9 on Galaxy Tab 10.1
PART I: Installing Requisite Recovery
- It’s important you’ve the proper drivers installed. If you have installed Kies, you already have the drivers, so download them only if your Tab doesn’t get detected.
Download Drivers | Alternate Link
- Download the recovery file which we need to flash in order to flash the ROM.
Download Recovery | Alternate Link | Filename: recovery.tar.md5
- Download Odin software, which will be used to flash the recovery.
Download Odin 1.85 from → here.
Filename: Odin 1.85.zip | Size: 199 KB
- Extract the contents of the Odin 1.85.zip file to a folder.
- Disconnect your tablet if it’s connected to PC and switch it off.
- Now, put the tablet in Download Mode — press and hold these keys together: Volume Down + Power. Right after the screen turns on, you’ll see a menu. Let go of both buttons, then press the Volume Up button to continue to download mode.
- Open Odin — double-click the Odin3 v1.85.exe that you got after extracting the file Odin 1.85.zip.
- Connect your tablet to PC now. You should get the message “Added!” under Odin’s message box in the bottom left. If you don’t get this message, then probably there is a problem with drivers. Make sure you’ve proper drivers installed.
- Now, in ODIN, click the PDA button, and select the file recovery.tar.md5 that you downloaded in step 2.
- Important! Do not make any other changes in Odin except selecting the required file in PDA as given in step 9. Leave all other options as they are.
- Now, hit the START button to start flashing the recovery. When the flashing is complete, your tablet will automatically reboot — and when you see the Samsung logo, you can safely unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of Odin.
IMPORTANT Note: If ODIN gets stuck and doesn’t seem to be doing anything, or you get a FAIL message (with red background) in ODIN, do the following – disconnect the tablet from the PC, close ODIN, remove battery, re-insert it, turn tablet on in Download mode, and do the procedure again from Step 7.
- After recovery is installed, go to the next part i.e installing the ROM.
Part II: Installing CM9 ROM
- This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
Important! Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
- Download the latest version of the ROM from the official development page. Open the link under the Latest nightlies heading from there, and download the latest version.
- Download the Google Apps package. This will install apps like Market, Gmail, etc. which are not present in the ROM.
Download Gapps | Filename: gapps-ics-20120429-signed.zip
- Copy the downloaded zip files from step 2 and step 3 to the internal SD card.

Here, press Volume Down to highlight the recovery mode icon, then press Volume Up to enter recovery.
In recovery, use the volume buttons to navigate/scroll and the power button to select options.
- Perform a Nandroid Backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this rom. To perform a backup, select Backup and Restore –> On the next screen, select Backup again. Go back to main recovery menu after backup is complete.
- Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete (this will not erase your personal files).
- Now select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the sdcard and select it.
- Confirm installation by selecting Yes – Install _____.zip on the next screen. The ROM will start installing.
- After ROM installation completes, select choose zip from sdcard again, then select the gapps-ics-20120429-signed.zip file to install the Google apps package.
- After the installation is complete, select go back and then select reboot system now to reboot your tablet and boot into CM9.

Then, select backup and restore, then select restore. Then press the power button again to start restoring your previous ROM. Once restore is complete, go back and reboot the tablet to boot up into your previous ROM.
