Let me prefice this by saying that my son doesn't know how to flash files, know what super user is, or know how to do much on his phone at all other than watch youtube and text.
He is running either official CM7-RC2 or RC3 for his P500, installing Link2SD and linking a few games is the only tweak I did.
He says it just started boot looping in the morning after charging all night.

My son was complaining his P500 was not starting, I figured it was a very low battery which ended up in a boot loop pattern. The next morning he said he charged it all night and it still wasn't working. Now I knew something was not right.

I pulled the battery, tried to offline charge it, gets stuck at lg logo. Tried to boot with no battery, just the usb plugged in, same bootloop.

Tried to boot into CWM by holding vol up/home and this screen somes up!

Now every time I turn on the phone I'm greeted with this Blue Error Handler message.

Code:
[Blue Error Handler V1.2] Arm 9 Crash!!
[Press Volume up key] To get Ramdump!!
[Press Volume down key] Reboot&savelog!!

<Additional Info about this crash>
Build ID: P500-M76XX-V20i-DEC-06-2011-XX
Time of crash (m-d-y h:m:s): 06-15-2012
Uptime (h:m:s): 0:00:04
Error in file hsu_mdm_apis.c, line 557
REX_TCB ptr: 0x01ea5640
tcb.task_name: PROXY_00
I can get into emergency mode but lsusb shows nothing, adb sees nothing, kdz says phone not found. I've tried shaking the phone like a fool over and over.
The computer and usb cable work fine on my two other P500s.

I'm kind of out of ideas.

You also might need the p500 drivers installed to use the lg thunder 1.5

You can download it from here

LGMDP doesn't connect to the phone, it waits at the select port screen. The drivers are installed since LGMDP can see my other P500s.

*edit* I was just thinking, I haven't tried connecting my other phones in emergency mode. Perhaps it is the drivers.

It did not detect mine either at first place... follow this.

1) close the LGMPD
2) plug the usb into a different port you are already doing
3) put the phone into emergency
4) connect
5) then start LGMPD

hope this helps

I wish I could get recovery going, but it always just hangs and the first lg logo if I hold any buttons down during boot. The only way I can get emerg mode going is to wait for the Blue Error Handler message to come up then hold vol down and back.

Once my phone got bricked and yes nothing detected my phone in emergency mode...so I just kept my phone turned off and plugged in and started doing what the thread said...then it automatically detected my phone and my phone's problem was solved
Please do it at ur own risk...I wont hold any responsibilty.

Mind if I ask how long have ur son been using this phone? To me, it looks like it is due to age. Well that is how I see it.

a cheap trick
This is what i tried on some other phone with similar situation...

use KDZ updater....to update v20g

put to emergency...
start the update (even if the phone is detected or not)
it may or may not install the rom correctly ......but after that LGMDP will start detecting your phone..

ya I've tried updating using KDZ updater many times it always hangs at the point where it says phone not found.

I use Ubuntu on my machine and its a pain to have to reboot to windows to try to flash it, are there any linux alternatives to LGMPD or KDZ? Maybe I'll try the official LG updater full program thing next time I reboot.

I just bought an atrix 4g for myself so I'm busy playing with my new toy
