I'd ask on forums like XDA Developers and Howard's Forums.
That said, since I don't need these and the office has a lot of phones, what issue are you trying to solve?
I have some problems about cert and imei and I search on the internet and I found the name of Darkmed Electronics. Now I am wondering that anyone who had used the Darkmed programs? Can I thrust them? Please help me. I think, they are good at their work and I had watched many videos on youtube but I need to find someone firstly.
