Flashed the rom, but used UK ROM, which is a clean OPEN (Bit nervous of using EU Open and configuring).
Both MMS and Bluetooth works great, but Ive now got H (HSPDA), Data & 3g Conn are both on, only have H now.
When I flashed, I followed the tips here, but:
I had ports 8 & 9 (it Used 8), but I found Putting into emergency download, clicking start on software, then plugging in the phone worked for me (In that order)
After re-reading this thread, I decided to re-flash to EU OPEN instead of UK OPEN and I can say the phone runs a little faster and smoother under EU, just wanted to add that, in case others were considering UK. I still have "H", I entered Virgin Mobile APN and downloaded "Network Setup" from LG Apps. I now have MMS, Bluetooth and full network tools.
I wanted to add this to back up what the_rider1920 and nasirahmed advised... use either EU Open or your carrier, as you run the risk of slow performance or even bricking it.
Thanks to all on this thread for great and consice posts and questions.
