I may not own nor intend to own an M3i Zero (GMP-Z003), but I think it's about time someone make one thread for all the problems so people can post here and someone who knows know how to fix the problem can answer their questions Sadly I am not the one to fix the problems, so don't rely on me, I can only answer the few questions I am I posting now. Q. Does the M3i Zero GMP-Z003 work with alternate firmwares such as the Quad-Boot, YSM3, or M3 Wood? A.No, sadly it was made with new hardware to lock those firmwares out. Q. Will it ever work with alternate firmwares? A. Give it some time, someone might work it out, but there's no promise Q. Does Sakura work on GMP-z003? I thought only Touchpod will do the trick. A. Currently, M3Sakura/iSakuReal/TouchPod will work. Q. My M3i Zero has a sleep error. It won't go into sleep mode or the screen flickers, what's wrong with it? A. From what I know, this error is either a hardware problem with the M3i Zero GMP-Z003 or a software problem Now start posting questions and answers and I will add them as they come.
