Background:

I bought this phone (brand new) in late November 2010. Within a week or two the phone started randomly powering itself off (even when the battery has plenty of charge left and the phone is just sitting on my desk). I hadn't performed any modifications at all (no rooting, no custom ROMs). Hadn't even downloaded any apps by that point.

I have never seen it happen... I'll use the phone like normal, the screen saver blacks out the screen like normal, and then I go to use the phone some time later (a few minutes, an hour, etc.) and I find that the phone has powered off on its own. It happens when I have the phone sitting on my desk, so the power button is not being pressed accidentally. The frequency is intermittent: sometimes it will go for a few days with no shutdowns and then sometimes it will happen twice in one day.

At first I thought it was a battery problem (I thought maybe the battery was overheating and the phone was shutting off to cool down) so I went to Telus and they gave me a new battery. I tried that for a week but the problem persisted. So I took it back to the Telus outlet again and they sent it away to an LG-authorized service center for repair. Doing this cost me $30 for shipping + service charges because I didn't purchase an extended warranty and I was 1 week past the 30 day device exchange period.

When I received my phone back (the service bill said that a "software upgrade" had been performed) the problem still continues! The phone has been shutting down at random exactly the way it did before it was sent away for service.

I didn't want to send the phone away for service again so I tried updating the phone's software myself - hoping this would stop the random shutdowns. I downloaded & installed the proper USB drivers using the LG Mobile Support Tool (I needed to put the phone in USB debugging mode in order for the mobile support tool to detect the phone). Everything was going fine, the LG Update Software downloaded the ~100mb firmware update file (I think V10s) and proceeded with the install but somewhere near the beginning of the install the phone went into Emergency Mode and stayed stuck there. I left it alone for 30-45 minutes just in case this was part of the install but after the program stopped responding I figured this wasn't normal. So I unhooked everything and took the battery out hoping it would reset itself but every time I would power the phone on it would bring up the LG screen then proceed to a bright yellow screen with the text "Emergency Mode!!" displayed.

I tried a few methods to get the phone out of emergency mode (hard reset/factory reset, leaving the unit off for extended periods of time, trying the mobile support tool again, etc.) but nothing worked. The only way I was able to get the phone operational again was to download the original firmware (V10g), install the MS XML sp3 parser and run the KDZ software updater (with phonemode "EMERGENCY" selected).

So with the phone running like normal again I figured I would try the update again. Now when I connect the phone and run the LG Mobile Support Tool it says a new software update is available but then when I click on "Start Updating" it goes through it's initial checks then says that this model cannot be updated, and it won't even attempt to download the new firmware update.

I have found the V10s available here: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500H/ATLSRB/V10s_00/V10S_00.kdz

But I am hesitant to try and install it with the KDZ updater in case something goes wrong.

My questions:

1. Is anyone aware of a fix for the random shutdown problem? I read through this thread

but I didn't see any concrete solutions.

2. Do you think the V10s software version will fix the random shutdowns?

3. Can you think of anything that I'm doing wrong? Why won't the LG Updater let me install the update now?

Thanks
