Heh...maybe. I have a business trip coming up in a week. Normally I'd shut the phone down during the flights, but I guess I'll be using "airplane mode" for its intended purpose instead. I am usually around power adapters so under normal conditions I can leave my phone on at all times. Quickbooting in to recovery and then booting from recovery back to ThundeROM seems to work, so if I ever need to restart my phone for any reason, that's the path I'll be going. My first immediate need to shut the phone down completely will be in a few weeks when I go on a four day backpacking trip. There is minimal coverage and no power, so I'll need to turn it off and only turn it on in emergencies. Hopefully I can work something out by then.
I just changed recovery from CWM to thunderc, so maybe that has something to do with it. My wife is away all weekend, so she'll never know if I spend the entire weekend trying to find the specific pattern of battery pulls and plug/unplugging that predicably recovers from the LG logo issue. If I can find one, I'll feel a lot better about continuing to fiddle with the phone. Other folks have reported that they have the same final product (ThundeROM 1.7, VC baseband) and can shut down completely and then turn back on without problem, so hwith enough patience and a reasonable level of confidence that I won't end up with a permanent brick, I think I can eventually get a working product on my phone.
Anyway, step 1 is to buy more beer, and step 2 is to swallow my pride and install Windows on my computer so I can use the LG installer if needed. Then I'm off to the races. It seems like a lot of work just to get a working phone, but I love this little phone and really enjoy showing up folks with their iph*#@s, so I'm going to get it working.
