Since the ICS update for the Galaxy Tab 10.1n (German Version of the 10.1 GT-P7500) still has yet to see an OTA update and I was eager to try out Jellybean. I rooted both my Galaxy Tab 10.1n and my Galaxy Tab 2 7.
Galaxy Tab 10.1n
The 10.1n is identical to the internationally shipped 10.1 (aka GT-P7500). The only difference is the Design due to the patent dispute with Apple in Germany.
Odin can be used to flash both Tablets, so keep it handy if you want to experiment in the future.
The Current CM10 with Jellybean is very stable and seems to be working fine. I havent fund any critical bugs so far.
If you have installed the Samsung OTA onto the Stock ICS Version 4.0.4 you might experience some difficulties installing the ClockworkMod Recovery. With the OTA, the Recovery will not be persistent and is thrown out after you boot the Tablet into Android. The link above on rooting the P3100 includes the Fix for the nonpersistent Recovery Manager. It includes a fix-recovery Zip that will deal with the problem. The rooting process is pretty much identical to the 10.1
Why install JellyBean?
There is one good reason – performance boost. The User interface is a lot faster and more responsive than ICS. I will add a detailed test for CM10 once it has gone out of experimental status.
So far the sophistication on the Roms nowadays is so good, that even experimental builds work surprisingly well compared to 2-3 years ago from the postings about Custom Roms on the HTC Hero.
