Well the soldering thing isnt a problem, I have a smd rework machine and various solder stations. If you can explain the software stuff you need, I can handle the hardware part of it. I have rooted all my android phones and played with roms in the past but Im not a software guy, by any means. I may have another 4500 at work, Im not sure..we sent so many back to United Radio which is the repair center Pioneer tells us to use. I am willing to sacrifice this one, and I have a ton of SD cards if you want me to try something, let me know.
