how i got into emergency mode

i hope this is any helpful info for the future, i was flashing a jb ROM and i had a feeling it wasnt going right cause it was stuck on the boot logo. so while it was still booting i did the vol up, power, and home combination. and it went straight into emergency mode. i only read the first 4 pages so if someone already pointed this out sorry.

The following key combos are for the P506 Thrive but I think also for the P505 Phoenix.
[ code]
Power+Vol up+Home == Recovery mode
Power+Vol down+Home == Fast boot mode
Power+Vol up+Back == Emergency mode
Power+Vol up+Vol down == Factory reset
[/code]

Oh god!

Damn it!

I used to have a LG Optimus One and when I was messing around with it I accidentally installed a HTC recovery. I literally bricked my phone very well bricked and it didn't matter what I tried I couldn't get it working. I was all this novel until someday I got very upset, threw it at the floor till the lcd crashed and went to the store to buy a new phone (by then I bought a Nokia Lumia 710 with Windows Phone)...

Dear lord, now, after months away of that bricked nightmare I found out the light in the end of the tunnel, but with one exception: the tunnel had fallen apart. Oh, my phone could be recovered using this tutorial... Why couldn't I find it earlier? It would save me nearly 300 hundread bucks I spent on my new phone (unbranded). And as long as I can remember I didn't need to do anything to boot it into recovery mode, when I turned it on it would automatically boot into emergency mode....

Darn!

Rom Manager Boot Loop after selecting Backup current rom

Hi.. I installed Rom Manager onto my friends p500,it was rooted earlier.. but it did not have a custom recovery ..so i flashed the latest cmw through the rom manager app.
After which i selected to create a back up.. The mobile restarted (to enter the cmw recovery for backup operation).. but soon after the restart the mobile got stuck at the LG Logo.. I waited for about 10mins and it did not respond. Then i removed the battery and then power it on.. but it is stuck at the LG logo.. I am unable to get into custom recovery.. (power+home+volumeup).
Also, Mobile is not detected when connected to pc.
How to resolve this issue?? Please help

Locate a recovery for your device and download. This is assuming that you are using a Windows PC. Click the link in my signature for Android Flash Recovery. Download AFR and unzip to a folder of your choosing. Read the README.txt or /help/index.html. Boot device into fastboot mode ( Power + Vol down + Home ). Run androidflashrecovery.exe. Browse to where you downloaded your recovery to and select it. Hit the "Flash Recovery" button. After flashing, since it's enabled by default, your device should reboot into the new recovery. If this doesn't work, more than likely you have disable USB debugging on the device. If that's the case, I hate to say, but you're kinda screwed.

Thank you for the reply

Was glad to help as best as I could. A word of warning tho, don't use ROM Manager for anything other than installing a recovery. It tends to mess things up on occasion. That's one of many reasons that I wrote Android Flash Recovery. You ended up getting lucky. I have a bricked P506 that no tools can fix :crying:. I think KDZ updater did that tho. It has bricked a lot of devices. I've tried to use LGMDP on occasion with no luck. How did you flash a recovery with it? If you don't mind sharing.

In the early days of p500 there was no easy technique to root p500 with Stock Roms.
We followed doktornotor's method to root and instal custom rom.
i.e flash P500-CWM-3.1.0.0.zip and root it through su-2.3.6.3-efgh-signed.zip

The complete info of HOW TO DO it is on this page http://xdaforums.com/showpost.php?p=15217609&postcount=3

Hope this would help you

shaking

its not shaking the phone... you should rather touch the screen by wiping it left and right, up and down or what ever way you want. there is a sensor or something like that when your phone is dead.

Hi, because with last update increased count of people with bricket phone, I just tryed search for way how to repair this phone. It seems, that last possible way how to save your phone is emergency mode.

I would like to notify you, that I didn't tested it (I'm had not luck enough to brick my phone yet ). I just searched and tried write this for help to others.

So, let's go on.

1) If it's not possible connect to phone via ADB (in Adroid SDK/tools run "adb shell") at all you will try next steps. If it will work, you can use another, verified tools like custom recovery or KDZ_FW_UPD (search on forum for more) [HOWTO] Flash original firmware on P500, )

2) If you fail in previous step, you can try enter into emergency mode manually and try to flash ROM with KDZ_FW_UPD:

Download KDZ updater and uncompress it
http://www.4shared.com/file/UleS4dP3/KDZ_FW_UPD_EN.html

Install msxml.msi from the uncompressed directory

Charge your battery to almost full state (I'm not sure, but it can be reason if phone doesn't start)

Turn phone off somehow (remove battery etc.)

Install drivers properly

Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments

Install the LG drivers by selecting the update manager from the lg site

Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.

Press and keep pressed "Volume up"+"Return" and connect USB cable to phone

Yellow screen with text emergency mode should appeared

Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.

Run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT (I have one report that CDMA mod works too)
Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)

I Recommend do not switch phone off. There was some people, which done it and after they were not be able to turn it on again. If flashing failed, just select some another mode and try it again, again, try shake/connect disconnect, again, again....

In KDZ file : Choose the ROM file you downloaded in the first step

Press Launch software update

Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.

Make sure that all update was done successfully. Phone should restart itself automatically

Disconnect the USB cable from the phone

Press the three button combo for HW reset of device i.e volume up + home + power button

List to do based on Zecanilis's [HOWTO] Flash original firmware on P500

3) Still no success? Wait for more "What I can do" or just go to LG and let repair on them.

http://android.modaco.com/content/l...modaco-com/321895/faq-gt540-reference-thread/

Please let me know if it works. I just searched for way and I haven't possibility to test this steps for now. I will do update if it will be necessary, same as I will try describe more about software which I founded.

Some experiences from thread(s):

About shaking (sorry, but I still can't believe... )

well its seems its not the shaking that helps.. rather you should touch the screen of the phone.. seems like there is a sensor or something like that. i got my lg p500 bricked sometime ago and tried everything.. and nothing worked because i forgot to turn on usb debugging while i still could...lol... but when i touch the screen it started to flash the stock rom. i guess even if your usb debugging is off you should touch the screen while launching software update using kdz updater

Please... help!

I tried to install a new rom to my LG Optimus One P500. But the installation failed, and my phone was stock in recovery mode. Then, i panicked a little bit, unplugued the phone, and it was still stuck on that yellow screen... so i removed the battery. Bad, bad idea.

Now, my phone just seem to be completely dead. I saw a lot of people talking about "Stuck with lg/android logo" of "stuck in recovery/emergency mode" or just in loopboot sh*t etc... But that is not my problem at all. Thoes people are lucky, they have at least a life sign from their phone...

Mine just don't even start up. Nothing. Black screen. And it dont look like i can boot it to recovery mode. I tried every damn combination of button i saw. Battery, no battery, plugued, unplugued, shaking it while dancing the rain song, sacrified some people in a volcano while holding volume up back power. NOT A DAMN SIGN OF LIFE.

How could this be possible?? It can't be really broke: its just the system that is messed up! When you mess up the OS of any computer, it just doesn't matter, you whipe everything and reinstall something. Its not like i stabed it with a fork, everything is physicaly OK with the phone.

Is there a way to reinstall the system on it? Why can't i go to the recovery mode? What's the matter of a recovery mode if you can just f*ck it up?

What can i do, please?

A flash filesystem is different than the filesystem on our computers. It's accessed in a completely different manner. And I don't completely understand it either. I've personally bricked two phones. Unfortunately I don't own a P500 and I think the button combinations are slightly different across the Optimus One Family devices ( P500, P505, P506, P509 ).

Kinda sounds like you are booting into recovery if you are getting a blank screen. Did you install a CWM recovery before flashing the ROM? Did you use Rom Manger to install the recovery? Did you select the correct recovery for your device? There are two of them, one for new baseband and one for old baseband. If you can get into Fastboot mode, the tool in my signature can get you up and running again.

Remove your battery. Press and hold the Power button to discharge any small amounts of juice retained by the device for about 10 seconds or so. Replace your battery. Now power it up and see what happens.

Also, if memory serves me, Power + Volume Down + Home == Fastboot mode, at least for the P506, can't find it on my P509.

UberNephew · Oct 18, 2012

Sorry, there is a misunderstanding. The screen is not blank, it stay black. Nothing show up. It just stay powered off.

Like this, its just impossible to get it mounted on my pc.

edit:
Also, for your questions, i used LGMDP. I don't know anything about the new baseband and the old one. What is it?

paul.n · Oct 21, 2012

If you had (stock) Android 2.2 Froyo, it's old baseband. Otherwise, it's the new one.
Regarding your phone, flashing you are under a big risk. Flashing doesn't modify the hardware, but it wipes something that is in the motherboard, what is necessary for boot and later writes it back I think. And if you pull the battery out, that file isn't written there and later phone fails to boot without that. So, you can try to go into emergency mode or try to flash it as is(if recognized), but otherwise your phone is a brick. Take it to service maybe. You can't do anything anymore.

I just want to thank The_Error, whose sticky helped me unbrick my phone. I have alot of people to thank for their posts, as I have been studying the forums for several months now, but I'll try to stick to the immediate story. Last night I was going to backup my rom and, since recently the phone had been in close proximity to a magnet, I wasn't sure of the integrity of my sd card's data, or the recovery. So I reflashed cwm 5.0.2.0. Must have had a bad connection. Went to backup rom from rom manager and no recovery. Stuck at lg logo. Tried repeatedly to access, to no avail. Grabbed laptop, hastily searching xda. Found this thread. Recently upgraded to win8 so I found my kdz folder under old windows. Reinstalled lg update tool so as to install drivers. Ran kdz in compatability mode for xp sp2 and as administrator. Pulled battery,sd,and sim(just in case). Replaced bat and set phone to emergency mode( back button + vol up, + while holding plugged in usb from computer. Tried in diag, and then emergency mode. Had a couple of errors( force close). Finally did run. Update finished. Bootloop. Pulled bat. Reboot. Magic. Froyo 2.2.2 v10s. Couldn't stand it. Had to have gingerbread with v20g baseband (never had luck before). Repeated process. Magic. Next project...super oneclick!!! I said before that I wouldn't be happy until I bricked my phone. HAPPY.

That is very, very similar to my story, except upgrading to Windows 8

Still, congratulations on the unbricking success!

Hello,

Had anyone tried "Recovery Phone" from the LGMobile Update app? It's under the "Customer Support" menu. Enter IMEI or S/N and see if it can bring it up to life.

Cheers.

Yes and it worked for me!! Yeah.http://xdaforums.com/images/smilies/rolleyes.gif
