Thanks a lot bro ! Works great but has some minor issues , for example keyboard crashed once on my device . Also it's awesome to see that tethering fix so early.
You should provide more details like firmware version, the physical state of your phone at least, before asking such questions. The issue can be of software or hardware nature but you didn't provided any useful information ...
Thank you ... I'm installing it right now :D
