I believe that your phone SHOULD be charging even though it has the exclamation mark boot screen. Just let it site there and try again in a little bit.
If anything, download flash tool and flash to latest firmware.
Ok, so say that I want to use the new firmware 2.1.1.A.0.6 which has the 55 baseband.
Can I downgrade use the 54 baseband on this firmware? And if so, can I use ROMS that say "for .435" because A06 and .435 are extremely similar just A06 is sup...
