Uhmm...Guys, I think I did something stupid as far as wontanserver is concerned. After successfully flashing 2 W800i's. I opted to change my wife's W900i which was on Hongkong Firmware. I was a bit reluctant at start because the system did not detect the W900i as opposed to the 2 W800i's. It said that I select the phone manually. So I did, after successfully flashing Main/FS, it went to the booting phone, this may take a while prompt. And it did take a long while, I guess this is the custpack portion of it, so after like 30 mins in the same state I took the phone off the USB, and of course it said Flashing Failed and ACK not found??? Did it a 2nd time and we're still stuck at that "booting phone, this may take a while" part and it's been there for like close to an hour already.

Here's the log, hopefully someone could help me out. TIA
