As we're here discussing about Ubuntu, I am giving any pre requirements but will let you know what you need.
- Rooted and CWM (latest version) Installed Galaxy Tab 2 (P3100)
- Should be running on CM10.1 Nightly ROM
- Some concentration and some luck
Note : The credit goes to @thatguruguy and @Menelkir @ketut.kumajaya for those work towards getting you and me the Ubuntu version for tab2 so thank them.
If you are yet to root and install cwm, go online and find out about how to do it.
I nor anyone above are responsible for any damage caused to your device directly or indirectly.
1. Download the device specific part for p3100 (that I've edited) from https://docs.google.com/file/d/0B6Za...it?usp=sharing
2. Download the latest Ubuntu nightly raring or quantal from http://cdimage.ubuntu.com/ubuntu-tou...alled/current/
3. Place both of these files to your external SD card (it's better to use external card instead of internal memory).
4. Backup your current Android to make sure you can come back at a later time. Use the CWM or the Rom Manager to backup the date. Keep the backup of data on external SD card and copy that to your computer for safety.
5. Reboot your P3100 into Recovery and do
- Data Wipe/Factory Reset
- Wipe the dalvik cache
- Format /System (this one is important)
6. Install quantal-preinstalled-phablet-armhf.zip or raring-preinstalled-phablet-armhf.zip (anyone of the file).
7. Install the device specif part that I've posted above.
8. Reboot System now and Enjoy the Ubunu
There is nothing much that you can do with the developer preview. So checkout how it is and feel happy that you could have a Ubuntu OS on your tab in future.
Cheers again to @Menelkir and @ketut.kumajaya and @thatguruguy for the device specific builds and the instructions.
I was told the Ubuntu can be installed also on the devices that has CM10.1 kernel and doesn't have to have complete os installed. So give it try and let us know.
I have made a video about getting the Ubuntu on your tab. This should help those that are having problems.
We're having a problem with porting ubuntu with the latest builds.the device specific part seems to be changed/modified.. our great devs are already working on it. If you still want to get a hands-on, try using the old version of ubuntu file.you will have to get into the parent directory to go back. I've tested the May 24th file and it was working. I will find a way to upload that build
Edit4: sorry it took a little long but here is the Ubuntu daily build of 24th may which was working with current build.
