My N900 telephony features have been going in and out for the last week, until I completly lost all phone function.

Figured it was my software so i reflashed it to pr 1.3, but didn't reflash the file vanilla emmc cause well it just would not remain in usb mode when i tried running flasher 3.5. Flasher 3.5 sees it in usb flash mode but then it doesn't and the usb symbol in the upper right hand corner disappears and flasher cant see it again.

The thing seems to work anyway. It seems to boot up just like a new n900, yet im still having the no sim problem. Swapped the sim card for my brother's sim. We both have tmobile. Still no dice.
