For most revisions (except rom 10 a86) the nexus or t911 or blue nexus are all fine. If you want to tackle rom 10 a86 you may need to think about a ubomb (jabs).
reading through the tuts on the nexus orange and the modded t911 (clear case) , i notice the power required for the nexus is 9v to 12v , and the t911 is 9v or are they both the same voltage , ie would i b able to use my spare broadband power supply on a t911 , just wondering if anyone here is using the clear case modded t911 with one as dont want to plug it in and naff it up
