Well, I finally got around to looking into getting Ice Cream Sandwich (Android 4.0.x) on my original Samsung Galaxy Tab. This is extremely experimental, and I can tell you that I had no 3G access using the 20120704 nightly build. However, the 20120708 build does seem to be working. I don’t believe that this due to the build, but that at some point in the process, I didn’t do a “wipe data” and “wipe cache”. From a stability perspective, you might want to stick with Gingerbread, and go with the latest Overcome version to get Android 2.3.6, however despite the rough start it does seem to be working well and I like ICS a lot.
Anyway, I am going to try recall the steps I took to get to this point. I usually try to document as I go when getting into these things, but this one was a challenge. However, I do feel that I have the basics, since I went through this several times.
There are two important things that are key. One is being able to get your Tab back to stock Ginderbread using Overcome. The other is getting the correct CWM Recovery version (220.127.116.11) installed.
I used Windows 7 64 bit to run ODIN to install the Overcome related ROMs.

Ensure that your computer is able to see the device properly. Windows 7 should be able to detect the Galaxy Tab without issue.
With all the software downloaded to a working directory, unzip GB-Stock-Safe-v5.zip, and the Modem-TMO.zip files.
Put the Tab into Download mode. To put it into Download mode, power it off. Then, hold the power button and the volume down on the volume rocker. Connect the Tab to your computer via the USB cable.
Start odin. Note: I am not sure what the deal with this is, but it is not clear where you can find this. I have been using a very old version, however, I did find this link to a version from 5/25/2012: http://androidfirmwares.net/Tools/Download/8 and other file sharing sites. You will know that the drivers used to detect the Tab are sufficient, if you see “COM:#” highlighted in ODIN.
Click the PIT button, and browse to and select the gt-p1000_mr.pit from the GB-Stock-Safe-v5 directory.
Click the PDA button, and browse to and select the GB_Stock_safe_v5.tar file from the GB-Stock-Safe-v5 directory.
Next, click the PHONE button, and browse to and select the modem.bin file in the Modem-TMO directory. NOTE: It is very important that you select the correct modem software. These are the instructions I used on a U.S. T-Mobile Galaxy Tab.
Click the START button. You should see a PASS notification appear in ODIN once complete, and the Tab will reboot.
This will install a fresh stock version of Gingerbread. Next, you need to install the Overcome kernel.
Run through the wizard on the Tab, and enable Mass Storage. Unplug the device, go to Settings/Wireless and Network/USB Settings and choose Mass Storage. Plug the Tab back in, and copy the Overcome_7_Series_v4.1.0_Wipe.zip file to the root of the Tab.
Power off the Tab and put in back into Download mode.
Launch ODIN, and use the same files for the PIT option and the MODEM option. However, for the PDA option select the Overcome_Kernel_v4.0.0.tar you downloaded earlier.
Click the START button. This time when it reboots the file system will be converted. This will take some time.
Once up, you need to put the Tab in Recovery Mode. Power off the Tab. Hold the power and volume up on the volume rocker. To navigate around these menus, you the volume rocker to move up and down, and the power button to select. Navigate to the “install menu”, and select “choose zip from internal sdcard.” Select the Overcome_7_Series_v4.1.0_Wipe.zip file copied to the Tab earlier.
Once completed, navigate to the reboot menu, and reboot the Tab. At this point, you should have Gingerbread 2.3.6 on your Tab.
Once up, disconnect the Tab from the computer, run through the wizard again and enable Mass Storage.
Plug the Tab back in, and copy the download CyanogenMod (cm-9-yyyymmdd-NIGHTLY-p1.zip), the Cyanogenmod 9 T-Mobile Modem software: (modem-galaxytab-t849uvjjb.zip), and Google Apps (gapps-ics-20120317-signed.zip) to the root of the Tab.
Put the Tab back in Recovery Mode, and choose the cm-9-yyyymmdd-NIGHTLY-p1.zip copied to the root of the Tab from the “choose zip from internal sdcard” option.
Now, this is where this get a little fuzzy for me. I believe I had boot issues at this point with 20120704 nightly build, however I noticed that the CWM Recovery version was now 18.104.22.168, so I did a “wipe data/factory reset” and a “wipe cache partition”. Then, I tried again and this time I also select the Google apps zip copied earlier and the T-Mobile Modem software: (modem-galaxytab-t849uvjjb.zip). This time ICS came up, and 3G worked, and seems to be working much better than I expected.
Below is a site that lists nightly changes, so you can determine whether you want to update:
CyanogenMod9 Changelog site: http://changelog.bbqdroid.org/#tenderloin/cm9
It would appear that using a ROM Manager is really not supported on this version of the Galaxy Tab. I haven’t tried to use it, because I have found nothing that indicates that it is supported.
So, if you want to update to a newer nightly build, I would recommend downloading the build and copying it to the root of the Tab and install it from Recovery Mode via “choose zip from internal sdcard”. You should probably do a “wipe data/factory reset” and a “wipe cache partition” prior to installing the update too.
UPDATE: I did an update to a last night’s build, and did not have to “wipe data” or “wipe cache”. It just took awhile for the 3G to come up after the first boot. Since then, it has been fine. Maybe you just need a little patience when installing the nightly builds.
