Custom Rom/Firmware Upgrade for UK LG GW620?

Hi,

My daughter has a UK LG GW620 on T-Mobile, and it is still running Android 1.5.

I can find quite a lot of info re updating the firmware, and my understanding is that there is a firmware available and this can be installed using fastboot.

The problem I have is that I can't get the phone to boot into fastboot. I have tried with and without the battery, pressing the space bar, space + menu, and space + enter. With the battery out, I just get an animation showing the battery cover being replaced. With the battery in the phone just boots normally.

Am I missing something here. Should the phone be rooted first, and is there anything else I need to do before booting into fastboot etc? None of the guides I have read say that the phone needs to be rooted, though that is what I would have expected.

I'd really like to get this sorted as the phone is fairly crippled.

 

Well, as seen as you're the only person to reply to my question, not far.

To be honest, unless I can find an easy solution I probably won't pursue it. I'll let you know if I make any progress though.
