The CyanogenMod team recently released its newest build of nightly ROMs, CyanogenMod 10.1 (CM10.1), for a host of latest Android devices including the HTC One and Galaxy S4 I9505 (Snapdragon 600). Now, the Galaxy Tab 7 GT-P1000 is the new entrant to join the Android 4.2.2 (Jelly Bean) party, thanks to the release of CM10.1 Nightly ROM.
The CM10.1 custom ROM is based on the original Android Open Source Project (AOSP) release, which is reportedly designed to deliver superior performance and stability than stock Android versions. As the ROM is still under development, it may harbour a few untested bugs or broken features. However, all such issues will be fixed in the upcoming updates.
NOTE: The instructions provided in this guide are meant for reference purpose only. IBTimes UK reminds its readers that it will not be held liable if device is damaged or bricked during or after the ROM installation.
- The CyanogenMod 10.1 Nightly ROM and the instructions provided in this guide are applicable for the Galaxy Tab 7 GT-P1000 model only. Verify the device's model number by navigating to Settings > About Phone.
- Backup important data and settings on the tablet via one of the recommended custom recovery tools such as ClockworkMod (CWM) or TWRP (it creates a complete image of the existing phone setup).
- Ensure the tablet has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) during ROM installation.
- Make sure USB Debugging mode is enabled on the device by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or go to Settings > Applications > Development (if tablet is running Android 2.3 or earlier). Otherwise if device is running Android 4.2, then do the following:
- Go to Settings > About Tablet
- Scroll down to the bottom of the screen and select Build Number
- Tap on Build Number seven times to unlock or reveal the hidden Developer Options in tablet's Settings. Now, select the checkbox to enable USB Debugging mode under Settings > Developer Options.
- Verify the device is factory unlocked (not locked to a specific carrier) with its bootloader also unlocked.
- Ensure the correct USB drivers are installed for the tablet on computer (download Galaxy Tab 7 GT-P1000 USB drivers)
- It is advisable to root your device before installing the custom ROM, as rooting enables full-functionality on your device.
- If the device is stuck at boot animation or results in boot loop issues after installing the ROM, then perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
- Allow the newly installed ROM to stabilise for five to ten minutes, before you start working on it.
- If the Status 7 error pops up on screen, it could be due to an incompatible device being flashed, or a firmware related kernel might be missing (for instance, a Jelly Bean kernel is required for installing any Jelly Bean ROM).

Step 7: Now, perform a full data wipe task to remove conflicts between new and original ROM. To do so, perform Wipe Data/Factory Reset, then choose Yes on next screen to confirm.

Then select Wipe Dalvik Cache under advance option. Once this is done, proceed to the next step.

Confirm the ROM installation on next screen and the installation process should begin.
Step 9: After the ROM is installed, repeat step 8; but choose gapps-jb-20130301-signed.zip instead of ROM zip to install Google apps.
Step 10: Once both the ROM and Google Apps are installed, returnto the main recovery menu and hit reboot system now. The tablet will now reboot into the newly installed ROM. The first boot may take some time (about 5 minutes) to complete. So, leave it alone.
