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!!

Build ID: P500-M76XX-V20i-DEC-06-2011-XX

Error in file hsu_mdm_apis.c, line 557
REX_TCB ptr: 0x01ea5640

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.

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.

Try this

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

...the second post in the link below solved mine...
http://forum.xda-developers.com/showthread.php?t=1710559
basically ends up with my trying to use lgmpd and seeing no phone at the select port screen
You also might need the p500 drivers installed to use the lg thunder 1.5

You can download it from here

thanks, same version I already had installed though

thanks, tried all 8 ports still no detection, changed my bios settings to use usb 1.0 only, didn't help, tried usb 2.0 highspeed didn't help, tried usb 2.0 full speed, didn't help

you could try flashing a new kernal/rom through the computer?

try to put phone in recovery with volume down button
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..

It was a Christmas gift but its been used quite a bit.

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

I just got the error it looks like you overclock too high of a frequency u got that instead of the kernel panic. I think it is because that our processor can't handle the oc and crashed.

He's never overclocked it on purpose, I just asked him, he doesn't know what overclock means.
Thanks for the input though

Went to researched and found out that the error happens wipe the /system isn't wiped properly. Try kdz first then install a custom recovery and wipe /system using amora recovery instead of cwm.

not to sound rude but have you read this thread? I've tried kdz multiple times in many different ways. Do you have any kdz tips I haven't tried?

Yeah I have. Uninstall usb drivers. Reinstall them turn off LG USB modem. Connect it to ur com. Shake the phone like crazy and hope it connects once connected just update.
Uninstalled-reinstalled, rebooted, lg virtual modem doesn't appear on the list until you get the phone to connect at least once, I shook shook shook, while in emerg mode, it never seems to connect, I tried lgmdp and kdz, both never connect. Tried with and without the battery in, never connected.
