If you see bootloader, it is not a brick
im not a Guru on this, but i had a similar problem.
I THink your phone is not bricked since you get to the bootloader,
ActiveSync wont work since there is no OS on your phone, but nevertheless the USB is working and you must flash a need OS through there.
Download the Wizard Love ROM, and keep it always in hand since it works 100% of the time.
Unzip it and then run: newromupdateutility_wizard_noid.exe
Thats pretty much all you need to do.
It will flash the wizard love rom, and youll get your phone up and running again in no time.
Dont stop or kill the process until its done, you will notice it hangs around 14% and 96%, it will complete , dont stop it, it takes about 10mins or more.
If you want to try a new OS, like WM6, read the first sticky on this forum http://forum.xda-developers.com/show...293480&page=14
. I have use this method and i went from Wizard Love rom to PDAVIET4. Then from PDAVIet4 to Aku3.3v2 (but did not work). I flashed wizard love, and then using the method i went from Wizard Love to Aku 3.3v2. Works like a charm.
Please excuse my english, im spanish.
