Help with my phone

[aultman07]

I've got two problems here. The first one happened a few weeks ago, the second one happened last night.

Ok first problem: my phone tells me to "insert sim card" even though one is already in there. I've tried everything: cleaning the sim card, cleaning the place on the phone where the sim card goes, bending the metal holder thing, putting numerous pieces of various types of paper in between the sim card and the metal holder, got a new sim card. I'm currently using the sim card in a razr phone, so it ain't the sim card. And I tried someone else's sim card in my phone and it didn't work either. Any suggestions?

Now the second problem is really serious: last night I installed Core Player on my phone and it installed fine and I watched a few videos using it. I've still got the phone connected to the computer through the usb cable. All of the sudden, it turns off. So I turn it back on, but it turns back off within 10 seconds. All it shows on the screen is "PDA Corner Ultimate". I've tried a hard reset and it doesn't work. I've tried 3 different batteries and that doesn't work either. Any suggestions?

Please help.

I think the next step would be to reflash the ROM, putting the OEM 6.1 back on it, Even if you have it now, just try reflashing it, its one step further then a hard reset.

I would have already tried that, but it won't stay on long enough for me to reflash it. The phone only stays on for like 10 seconds. It gets stuck in the splash screen.
