Tmobile ROMs can't be flashed through USB .. you have to use SD methode.

This slowness is a known bug in older WM2003 ROMs ... either to use a recent ROM like 4.01.16 or A30.09 .... or to install the fix named "clear_notify.exe" in your \windows\startup directory

Bad signal could be out of the RSU 4.21 ... depends on your network and the device type you can use a better RSU ... but it's a very risky action!!!
