Not sure if enough people who develop still have this phone, and sorry if this is noob to refer to but here it goes.
I was modding an exhibit II 4g for someone, and noticed the kernel this particular developer was using enabled him to put cm10 with android 4.1.2 on it, and it works awesome. So I checked the kernel out and he uses one written by "arco" which has his own website and writes code for any phone I'm guessing that would be compatible, it wasn't written specifically for the exhibit.
If anyone who has the know how and would be interested, the link to arco's website is:
So, the difference between the exhibit and the transform ultra is very slight, MSM8255 versus the TU's MSM8655 both of which are snapdragon s2, and the rest of the phone specs are similar. So is his work useable for making a kernel that would enable cm10 for tu?
