Before applying this tutorial on your Samsung Galaxy Tab 10.1, keep in your mind that YOU WILL LOSE THE WARRANTY OF YOUR DEVICE.


Be sure to make a backup of your data.

Those are the file needed to apply this tutorial on the Samsung Galaxy Tab 10.1 P-7500 (3G and Wifi) :

Odin3 1.85 (Used to flash the Tab) : Odin3 v1.85.zip

Official Stock ICS Samsung Galaxy Tab 10.1 P-7500 :


ClockworkMod Recovery : ClockworkMod_Recovery_v5.5.0.4_P75xx.tar

MOD Modem : CWM_I9103XXLQ3_Modem.zip

MOD Voice Call : Voice_Call_Enable__Stock__ICS_4.0.4_ROM_Build_1.zip

First Step – Copy the files to your tablet :

Copy CWM_I9103XXLQ3_Modem.zip and Voice_Call_Enable__Stock__ICS_4.0.4_ROM_Build_1.zip to your device

Second step – Update your device Android version (Skip if you have the 4.0.4 version):

If you have a previous version of Android, there is many other ROMs where the Voice calls MOD was tested on and worked.

- [Deodexed]Stock ICS rom XXLQ8 & Stock ICS rom XWLP5 - Get it Here
- [Offcial] Stock ICS rom XXLQ8 & Stock ICS rom XWLP5.
- [ROM][ICS] JellyBeanRom ICS - Get it Here

Personally i always use the official ROMs with my devices.

So here is how to upgrade your P-7500 version to Android ICS 4.0.4 .

1 – Go to the download mode :

How to set Galaxy Tab 10.1 to fastboot.

2- Open Odin3 and choose in PDA the Official Stock ROM Android ICS for Samsung Galaxy Tab 10.1 P-7500 file :


4- After installation the Galaxy Tab 10.1 will reboot with the ICS version.

Third step – Change the default fastboot with ClockworkMod Recovery (CWM) (Skip if it’s already installed):

Changing the default fastboot will allow us to upgrade and add any other features to the device ROM easily, by just placing the zip files into the /sdcard path and install them.

The default fastboot doesn’t have this feature (protected)

1- Go to the download mode like the previous step :

Choose “ClockworkMod_Recovery_v5.5.0.4_P75xx.tar” and press “Start” :

After installation your device will reboot as usual, now go to the fastboot (same as download but at the 2nd step choose the fastboot mode in the left)

After you press the Volume UP you’ll enter to CWM :

Note : Other versions of CWM will not work, cause you’ll stuck in a rolling screen like this :

Last step – Install the MOD from the zip :

After rebooting and entering the fastboot mode select “Install zip from sdcard” :

2 – “Choose zip from sdcard”

3- Choose “CWM_I9103XXLQ3_Modem.zip”

4- Yes

5 – Installation progress of CWM_I9103XXLQ3_Modem.zip :

6- Repeat from step 3 with the file “Voice_Call_Enable__Stock__ICS_4.0.4_ROM_Build_1.zip” :

After finishing installation, press the power button for about 6 to 8 seconds to reboot the device .

After rebooting you’ll get the Phone icon with your apps, and it would be added next to your contacts details as well.
