We have had unofficial releases of CyanogenMod 9 builds for months on the Galaxy Tab 10.1, but today we get our first ROM from an official channel. Steve Kondik, CyanogenMod founder who now works for Samsung, released the pre-alpha version of CM9 for the Galaxy Tab 10.1 today via a post on Google+. You can download the files here.
The installation is quite simple. Just flash the recovery image in fastboot and then the .zip file.
I am not sure what the differences are, or if there are in fact any, between the CM9 ROMs that have been on XDA for months and this release. If you notice any differences let us know in the comments!
