Update Galaxy Tab P1000 to Jelly Bean 4.2.2 with CM10.1 Custom ROM

The Galaxy Tab P1000 users can now update their tablets to the latest version of the Android system, the Jelly Bean 4.2.2 system, as the CM10.1 custom ROM firmware has been made available for the mentioned device. And for learning how to flash the Android 4.2.2 OS on your Galaxy Tab by installing the CM10.1 custom software, you will have to complete the present step by step guide. Here, you will find all the details needed and required for the update operation along with other relevant info, so read and apply the next lines if you want to easily resolve the flashing procedure.

CM10.1 is one of the most popular Jelly Bean 4.2.2 based custom ROM released for the Android platform, the firmware being available and suitable with almost all the Android powered devices out there. The software brings many bug fixes, extra features (that cannot be found in the default version of the Jelly Bean OS) and capabilities that can be used for improving the performances and the looks of your Samsung Galaxy Tab, not to mention that the platform will be opened for further changes as you will have access and control over the internal system of your tablet.

Unfortunately, the present update is still in development stage as we are dealing with the Experimental variant of the CM10.1 custom ROM. So, there might be some minor issues and bugs included in the Android Jelly Bean 4.2.2 system, meaning that not all the features will work on your Galaxy Tab P1000. Don’t worry though as the problems will soon be resolved and you will be prompted with the stable version of the CM10.1 firmware. But, until then the Experimental software is all you get for your Tab.

Now, if you want to flash the Jelly Bean 4.2.2 based update on your Galaxy Tab, you will have to prepare your handset first, as the installation procedure is complex and risky and has to be carefully applied. The first thing to do is to root your tablet, or else the tutorial can’t be performed. CM10.1 is a custom ROM and such platforms can be updated only on rooted devices. Anyway, do root your Galaxy Tab and then resume the rest of the pre requisites.

Up next, you need to replace the stock recovery image from your Galaxy Tab with a custom one. The best will be to install CWM recovery on your tablet. CWM recovery will then be used on the update operation as the CM10.1 software will be installed by accessing the mentioned tool. Take note as a custom recovery image can be flashed only on rooted systems.

A negative aspect related to the mentioned tasks is referring to the warranty of your handset. Unfortunately the Galaxy Tab warranty will get voided so if anything bad happens and you manage to brick your tablet, you will be by yourselves. Anyway, do remember that this is not permanent; you can choose to restore the warranty if needed. You just have to downgrade to stock ROM, or to update with an official release of the Android OS. Then, the root access will be revoked and the factory restrictions reinstalled.

Now, in order to avoid the unpleasant situations, before detailing other info related to the update process, you will have to backup the Galaxy Tab data; a wipe will have to be applied (I will show you how a little bit later) which means that all of your personal info which is saved on the internal storage memory of your handset will be erased. So, as you can tell, a backup is a must have; save anything you can, starting with the text messages, EFS folder, market apps, internet settings, call logs, contacts list and so on. Also, if possible (still recommended), use the custom recovery image and apply a Nandroid backup too.

As soon as the up mentioned tasks are completed, you can concentrate on applying the general pre requisites; I have explained the same during the list from below, so don’t skip the next section.

  • Be sure that you can use a computer or notebook where you will download the CM10.1 firmware file. The, the Galaxy Tab and its USB cable should also be near you.
  • On the computer there shouldn’t be installed or running any security tools, like antivirus programs; these programs are usually interfering with the update operation – you will have problems when downloading the ROM and so on.
  • Your tablet should have enough battery power left – more than 60%; if not most likely, your handset will get turned off while you will trying to install the Jelly Bean 4.2.2 based custom software.
  • Enable the USB debugging option on your device by going to “Settings -> Applications -> Development -> USB debugging”.
  • This step by step guide / tutorial is compatible only with the Samsung Galaxy Tab model number P1000; don’t use the next steps if you want to apply the CM10.1 ROM on a different device as you can end up in bricking the same.

How to Update Galaxy Tab P1000 to Jelly Bean 4.2.2 with CM10.1 Custom ROM Firmware

  1. As already stated, on your computer you need to download the firmware file.
  2. The Experimental version of the CM10.1 ROM can be downloaded from here.
  3. Don’t extract the file, just save it on your PC.
  4. Then, connect your Galaxy Tab with the computer via its USB cable.
  5. Select the downloaded file and copy-paste it from the PC to your tablet.
  6. Unplug the USB cable as we no longer need to use the PC.
  7. Turn off your device.
  8. Reboot by pressing on the Power, Volume Up and Menu buttons at the same time, for a few seconds.
  9. The recovery mode menu will then be displayed.
  10. Now, by using the same first select to wipe the system; go for “wipe data factory reset” and “wipe cache partition”.
  11. Then, return to the main menu of recovery.
  12. From there, this time select “install zip from SD card” followed by “choose zip from SD card”.
  13. Pick the update file now and flash the same.
  14. When the installation procedure ends you need to select “+++go back+++” and “reboot system now”.
  15. Note: in case, in the end you will get stuck in a boot loop, then you have to reboot into recovery once more; from there re-wipe the system of your tablet again and everything should be working as planned.

Congratulations; you have updated your Samsung Galaxy Tab to Android 4.2.2 Jelly Bean OS, as the CM10.1 custom ROM has been successfully flashed.
