[Q] P500 stuck in emergency mode, not detected by computer

I have tried the LG update software, nothing detects the phone, it instantly boots into emergency mode hoping I have not bricked the phone. This all happend while trying to downgrade the baseband and it just stopped at about 25% and stayed there for ten minutes, I attempted to reflash and the same failure happend, I then rebooted the phone and it has been in emergency mode since then with no detection at all.
did you flash a custom rom? or were you using the stock lg rom
try use other usb port ???

check downgrading ur phone detail just flash ur desired android version.
if sucessfull via lgmdp(latest method) search threads for lgmdp method or use kdz which solved all probs.
Try to enter emergency mode with vol up + back key + power button (not just power button) and then connect it to usb.
I have tried the kdz(after emergency mode issue) and lgmpd method already as it was required for the baseband flash the first time, I have clockworkmod recovery installed and cannot boot to that, was downgrading the baseband so I could go back to using CM7, as we speak I tried using CDMA setting in KDZ and I seem to have gotten a response, will update with whatever method works to unbrick
well after using KDZ method in CDMA mode, with shaking the phone, crossing fingers toes arms legs and eyes, I flashed riginal firmware and unbricked my phone, thank you for the links, after about 8 different pages I managed to get it working thank you all

try 3 button combo home+vol down + power and see if it comes out of lg logo and boot
I'm stuck in the Emergency Mode!! yellow screen with my P500 too.
I tried with KDZ Updater in all possible combinations and got the error "Upgrade error WParam:100. LParam:502" at each attempt.
I tried these rom's: V10A_00.kdz, V10B_00.kdz, V10E_00.kdz, V20B_00.kdz.
With LGMDP THUNDER v1.5, but I run into this error, after pressing the Start (write ROM button): Error! Partition Table.
Help!
I opened a dedicated topic here http://forum.xda-developers.com/showthread.php?p=17307504#post17307504.

I know it sounds weird but it did for me.

Hello, my P500 is not detected any more by computer!
I looked over the internet and it seems a hardware problem. The phone is charging but cannot be detected as hardware. Unfortunately to resend it to warranty I must first remove Superuser because I rooted my phone. Is there any way to install the firmware once again from the sd card? I cannot make it through a computer because as I said before is not detected. I have custom recovery installed: ClockWorkMode 5.0.2.0. I looked over this forum and found some custom Recovery Zips, but I don't know how to use it. Any idea please? I must get rid of root access so I can return my phone to warranty! Thanks!

Strange stuck LG P500

Hi, i've a strange (but i hope common and resolvable) problem.
After all, i say that i searched through the forum (with the search function) but with the solution that i found and tried i didn't solve anything.
I start saying that i got a p500 with a broken sdcard reader board (it simply doesn't have a microsd 'cause doesn't recognize).
That phone some days ago just shut down and went stuck on the LG Logo.
I tried at first the hard reset (home+vlm down+pwr), nothing happens.
I tried then the recovery mode and try to update with lg updater, and didn't work, lg doesn't recognize the phone on the updater (but on the main screen of the BBc app does).
After some tries, (dumb tries, for example leaving it without battery for some hours), and searching, i did two ways:
-KDZ Firmware update way, selecting 3gqtc and diag on lg logo, or recovery (and recovery sc) on recovery screen, nothing done.
-LGMDP for installing fastboot and CWM and v20e. It completes the operation but nothing changes, the lg is still stuck on the lg logo.
The last thing that i noticed is that one time, powering on the phone, button's leds flashed about 4-5 times. but if i try to re-do the action, doesn't get anymore.
I would know if there is another way to exit from this stuck-screen.
I hope opened the topic on the right section.

When you say recovery and recovery sc, you mean EMERGENCY and CS_EMERGENCY, right?
So, you tried selecting these options while on the black menu of recovery (like the Clockworkmod one) or on the yellow screen saying Emergency Mode!! ?
In case you were on the recovery, try the following: remove the battery and, while holding the volume up and back keys, connect the phone to USB. After that, try using KDZ selecting EMERGENCY.
But in the case you were correctly on the emergency mode and just used the wrong words here, then I'm sorry but I don't know what else you could try to solve your problem (wait and see what other ideas people will come up with).

Yup, sry it's late night and i got confused with words.
I'm can go on the yellow screen and "EMERGENCY MODE" is texted on center.
And on KFC Used both modes of emergency (even diag).
I tried to do this without battery, but the result is the same. When it reboots stucks up on the lg logo. =(
Uh, i forgot to post the errors of kdz:
Upgrade error
WParam: 100
LParam: 500

lg optimus hub bricked/stuck

Okay long story short, I attempted to install transparent cm7.2 status bar and phone bricked (fastboot). I fixed it and installed other phone model's cwm with windows cmd command (stupid, I know). After this I'm always stuck at lg screen. Can't get into recovery either. Lg update tool does not find the phone, neither does cmd.exe. I sometimes get the ''colored snow screen'' or whatever I should call it. But it doesnt change the fact that the phone can't be recognized by anything.
What should I do? I ran out of ideas. I can't turn the phone in any mode, it always starts with the lg screen.
bump
bump. dammit, am i really screwed? I managed to get a notification about new hardware installing yesterday but none of the driver stuff I had worked so I left it the way it was and did not install anything afterwards.
I've just entered Emergency Mode!! with volume up+down+plugging into usb. Some driver got installed but there's still no lg stuff in device manager
Completely bricked.
Doesn't turn on at all.
Okay, any excuse I can tell the phone suppliers?
cek recovery
whether you have flash before CWM recovery?
if you might have tried to go to CWM pressing the power + vol down
if you managed to do as they pleased
The phone is a brick. It doesn't turn on in any way. Completely dead. If I could get to CWM I wouldn't be asking for a story to tell the phone suppliers xD
You can use KDZ Updater and also download original lg firmware. All can be found here in this forum.

I am able to go in SW upgrade mode, but after 2-3 minutes the phone get off, i think the battery is out, is it possible? How can i charge it? The charge from phone turned off doesnt work in my last rom

I think in that case you would need another working device to charge your own battery.
