Phone will not boot past recovery. Please help, major panic!!

Oh dear.....I hope I haven't destroyed my O3D....
I was attempting to install the V10D update, so used the backup I took right after rooting and installing ROM Manager to restore the phone to its status before installing the performance pack. If I tried installing the update OTA before this I just got an invalid package error.
So the restore went well and it rebooted fine. So I ran the update again, and it downloaded and appeared to install, but when the phone rebooted it just booted straight into the recovery. I tried to get it to reboot again, but again it just booted back into recovery.
Ok, nothing to worry about I thought, I just ran the restore again with the same restore point as before....but after it finished it's still booting back up into the recovery!!! No matter what I do the phone just seems to keep booting into the recovery menu. I've tried booting into emergency mode by powering the phone off, then holding the UP Volume key and holding power, but it doesn't seem to work.
Can anyone help? Please?
Lil update -
When powering off the phone and then connecting it to the USB cable, it automatically boots into recovery mode without me even touching the power button. At this point the LG Mobile Update detects the phone and advises me that there's an update available. I try to apply this, but after entering the SN and IMEI, it just gives me a message "Updating is not possible any longer due to a fatal error while the LG Mobile Phone Software Update". I get the same error if I use the recovery Phone option. This always happens at the download stage, so is it possible that it's just failing to download the update from LG rather than actually do anything with the phone?
Please don't tell me I've ruined my brand new phone!!

Unfortunatly, you've managed to do the same as I have... leave the phone for e a few days and wait for a rom that you can install via clockwork recovery, you'll have your phone up and running again. Dont do as I did and wipe the recovery from the phone, it will result in a total brick (or at least a brick till LG releaase a full rom update (could be months yet...).

Oh man, I'm panicking so much that I might have ruined the phone now.....

I'm not sure what I'm looking for there, I've looked through that thread but it doesn't seem relevant to the problem I'm having.

I have the same problem, if you put it into emergency mode you can update to 10d but then its even worse then you are stuck in the firmware update screen
tomorrow I leave on holiday and was planning for nice 3d pictures and movies but I am screwed...

Don't panic, I managed to totally brick my phone today and LG told me to send it back for DOA but I managed to recover it in the end.
My phone wouldn't show anything on the screen, it remained black so I can say your position sounds much better than mine.
What you will need:
USB Drivers - Download from here (Check note)
LG Mobile Support Tool (LGMST) - Download from here
Before you start: Disconnect the phone from the computer and totally remove the battery.
So here we go:
!!!REMOVE ALL THE LG USB DRIVERS FROM THE SYSTEM BEFORE YOU CONTINUE!!! Go to add remove programs, select the LG United entry and then uninstall it.
First install the USB Driver from the link above and wait until it has finished with the setup.
Then run the LGMST. When it starts and it says "Disconnected." then put the battery back to the phone and connect the phone to the computer.
Press ONLY the Power button and wait until something happens. If you see that the phones boots and the LGMST starts it by itself then wait till it stops with all the information gathering stuff.
Then regardless of what the program says of you having an update or not, DON'T START THAT UPDATE!
Click on alt on the keyboard and the from the menus at the top select Customer and then emergency(the last option).
Type in the phones IMEI (located at the box of the phone or on a sticker under the battery) without dashes, just numbers.
Finally click on Check and follow the instructions on the screen.
You should be ready as new after 10-15 minutes with the standard V10B firmware and you should not even lose data.
Tell me if that helped so if it didn't we can still fix it I'm sure
Note: I'm aware that 3.3.0 is the latest USB driver that it ships with the phone but for some reason I had only success to flash the phone using the older 3.2.1

That does not work for our problem, just a blank screen is better than stuck in firmware update mode :s

I'm afraid that didn't work (I think I'm gonna cry soon)
When I go to the Customer Support option, the last option isn't called Emergency it's called "Recovery Phone" and seems to launch exactly the same thing as it does if I click the big "Start Updating" button. There is no option named Emergency at all. Does that mean my phone isn't/wont/can't boot into Emergency mode?
I don't even hold down the power button for my phone to switch on, the second I insert the battery it boots into Clockwork Recovery. If I power off the phone and connect the USB, I don't get the battery charging animation or anything, the screen just remains completely blank. Then if I press the power button (alone or with anything else) it just boots to Clockwork recovery.
The LG Mobile Support Tool seems to detect the phone in this state, but as I said, when it tries to do the download, I just get an error saying "Updating is not possible any longer due to a fatal error while the LG Mobile Phone Software Update". The version of the Mobile Support Tool that it's installing is 1.5.1.8 after downloading from your provided link, just incase you need to know that. It seems the tool automatically updates itself on every launch.
Someone also seems to have posted the actual ROM in this thread, http://forum.xda-developers.com/showthread.php?t=1155874 would installing this perhaps assist? Is it even possible to install this when my phone wont boot up past the recovery manager? If it is possible can someone perhaps advise me how?

Unfortunately the phone wont boot into Emergency mode. The clockwork Recovery mod seems to have taken over all of the boot options. If I hold the volume up key and press the power button, nothing happens. If I hold the volume down key and the power button, it boots to clockwork recovery. If I just press power, boots to clockwork recovery.
Is there any way to strip off Clockwork recovery and restore the original/stock recovery onto the phone? Or even just remove Clockwork recovery so that it just hangs on the LG boot screen? (See reasoning for this below)
I can still select the USB mount option in Clockwork recovery and the PC still picks it up as a storage device and I can browse around.
The phone is only 7 days old, so I'm almost tempted to just delete the internal memory so that clockwork doesn't show up, then take the phone back to the store and say it wont boot up and try to get it replaced.
Or what would happen if I renamed the clockworkmod folder on the phone's hard drive?
(Just another note, I don't have an external SD card in the phone, just the internal memory)

If you can upload a backup of the ROM and advise on how to install it via Clockwork, you will be my hero.

How else can I put it into Recovery Mode? How can I tell if I've done it right?
I managed to hold the up volume key and hold down the power button, and the LG Mobile Update detected the phone whilst the screen was blank. I thought that meant I was in recovery mode?
I should point out that the LG Logo wasn't flashing up however. I only ever see the LG Logo before it boots into Clockwork RecoveryMod

I also got that fatal error thing when i bricked my phone. For me the phone would start flashing but it got stuck at 17% and then an error followed saying that there was a communication problem between the phone and the pc. My solution was to switch from my desktop computer to my laptop and the procedure ran smoothly after.
You said that the phone powers up directly after you connect it to the pc and while having the support tool running?
You can try to shut it down so it shows a black screen as you said and then try to boot into emergency mode with the vol.up+power button.
The windows sounds might help you on that. you can listen from the computer when the phone connects/powers up or not.
EDIT: Just read your post, if the phone remains black is a good thing.

if your update fails or goes into clockwork recovery etc you will need LG mobile update on your pc and install the lg p920 drivers
turn your phone off take the battery out leave it for 10 sec, connect battery and usb cable hold power and volume up hold it for 10 sec let go then do it again for 10 sec
now run LG mobile update click customer support > recover type your imei let it update once finished power up phone now you will get a screen on the phone that says updating let it update

Well I'm not sure what I did differently. Not sure if I wasn't pressing the button hard enough or my finger was slipping off, or if I've just somehow tricked the phone, but the LG Phone Update from the Phone Recovery option is now running.
I've been doing the same thing I was doing before (or at least thought I was doing) and I'm not sure what I did differently....but....fingers crossed..... the download will finish in 40 minutes (on a crappy connection at the moment) so I'll be able to see what happens then....
UPDATE -
Progress, though not quite yet success.
The LG Mobile Support tool downloaded the software and applied the update succesfully, though my phone didn't automatically restart. I pressed the power button however and it loaded up and not into Clockwork Recovery Mod. It's not however sitting on an "Updating Firmware" screen and the progress bar doesn't seem to be filling at all.
How long does this part of the process normally take?
Does the phone need to be connected to USB for this part of the process? The LG Mobile Support Tool says the phone is disconnected so I'm guessing there's no active data connection between the PC and phone, just power.
Does this normally take a while? Or should I perhaps try the recovery again?

This is only supposed to happen when you apply the OTA update. Try to reapply the stock firmware in emergency mode. After the program applies the firmware, it should boot up the phone by itself in android and give you a success or finish message on the computer.

Is applying the Stock Firmware not what I did with the LG Mobile Support Tool when it downloaded that huge 300MB+ file?
I have contacted the customer services for Carphone Warehouse, and the guy advised that if the phone seemed to have developed a fault and wouldn't start, then since it's within 28 days of purcahse I can get a like for like replacement. Might have to go ahead and do that this evening.

[Q] Possible Bricked P920 (Stuck on Boot) [SOLVED]

Hey there,
In a bit of a dilemma here with my phone.
I was running the XBSA V21E Gingerbread with ICS Theme ROM with the TitanKernel V0.4.2 V21D 09-04-2012.
I decided to install I a new rom without a flash, The Promethius Project V1.4 followed with he latest Promethius Kernel. All went successfully with no errors, according the the boot anyway.
ok...after trying to reboot many times, I have not been able to get any further than the 'LG Boot Logo' I left it on last night as I couldn't be bothered trying to fix it at the time and it stayed on the logo for over 7 hours. (Figured it would nonetheless)
These are the steps that I have tried, of which wont work for me:
1 - Turn off your phone
2 - Press power and volume down until the LG logo apears.
3 - Release the power button but keep the volume down pressed.
This takes you to the recovery screen.
1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)
6) Click on User/Support then emergency mode, insert your IMEI and click on check - I get a popup saying "Please Check Phone Information Again"
Iv'e done everything with and without the battery in place, I have removed sim and SD card.
Any help would be greatly appreciated.
Kind Regards.
EDIT: Solved!!....huh? How?.... Well my lesson learned is, flash before installing a rom....[GUIDE] Recovering from brick/bootloop
Worked for me anyway

if the case is stuck on LG logo, go to CWM menus, wipe all and reinstall the ROM, install it twice, reboot. (always work for me if I got stuck on LG logo).
sorry for my bad english.

I mentioned that I can't get to the menu in my post.

ow sorry, I didn't notice that you can't go back to CWM menus also.
you are using LG Mobile Support Tool right for recovering?
If not, download LG Mobile Support Tool and run.
- Change Country in Option&Help, select country.
- Download the usb driver, if you are not installed yet.
- Take off your battery
- Connect the phone while holding vol.up and wait until LG support tool detect your phone
- If it connected, go to Customer Support and select Recovery Phone
- insert your IMEI, ok
- wait until it finish downloading and recovery your phone.
If not succeed on downloading, try install PC suite first and redo the steps.
Hope it's work.

I don't mean to be rude, but did you read my post at all? I mentioned that I can't do that either.
1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)

OMAP4430 appears and disappears again and again

Hi, its been almost half a year now since i bricked my O3D, im still having problem solving this. I'm still newbie at this so i dont how to solve it. Still stuck at where you fastboot the omap thingy. I cant get into download mode i've tried all sorts of ways and still no luck. Did install OMAP4430 and after that the fastbooot one, tried holding vol+ and plug the cable and no logo appeard on my screen its pitched black only the search/back/home/menu buttons lights on. Then after a minute or less its turn off and the OMAP4430 in the device manager started to appear and disappear all the time, also i cant seem to find the LG port device on my device manger Help?

for pc driver installation. It is rather fiddly, so proceed slowly and read all details carefully. Once it is correct, however, you can use LG Flash Tool, Fastboot, ADB, or whatever for this device.

did all its says from the top still i cant find the LG port and my device manager keeps on refreshing and the OMAP device also keeps on appearing and disappearing.
Btw i did went(last year ago) to LG costumer service and after a week they said that the main board is the problem, and it cost more likely 40-50% of the original price of my phone Up until now im still hoping for my phone to be fixed.

I would try again; there are a lot of little details there that are easy to miss the first 5 or so times trying to do it. Rebooting pc between each step, for instance. You must be logged onto pc as administrator also. It took me some time before I was able to install the drivers correctly and that was before I wrote it all down in detail.
If it really is the board (I picture a scenario where they want to sell you a new phone) then none of this will help. However, the omap4430 blinking on and off tells me it is trying to connect, but is not installed correctly.
Take your time with each part and carefully check every detail.

omapboot and sw are two different modes.
the "LG port device" appears only in sw mode
omapboot:
you need omap for flashing the custom bootloader
enter the mode: remove the battery and plug your phone to usb while holding vol +, for me its working also when i just plug the phone without battery. if the device is appearing to fast in the devicemanager plug the battery into the phone, and the device should stay and you can install the driver,
sw mode:
is needed when flashing wit lg flashtool or smartflash etc for flashing stock roms or simliar.
you can enter that mode:
plug your phone to usb while holding vol+ with battery insert, and keep holding until the phone screen shows sw and some korean letters.
now you can set the port to 41 in the device manager

yes, in the sw mode, thats where i got stucked did hold vol+ w/ and/or w/o battery (tried both) no logo and korean letters appeared on my screen totally pitched black only the search/back/home/menu lights up after that the omap keeps on appearing and disappearing. Tried different cables btw im using win8 and i also tried fresh start on other laptop's of my friends. It's very frustrating

anyone had some success here? I have as well OMAP device on-off, I can go to SW Upgrade mode (no Korean letters though) and to stock recovery.... Tried LGFLashTool2014 (but it crashes on "Read Phone information) and "Flashtool"-Tool, which can enable fastboot and flash uboot, etc. But to no success...

Have you installed OMAP drivers properly?
Open Device Manager on your PC and search for OMAP4430 (it connects and disconnects continuously) so, quickly double click on it and chose update driver. Select browse my computer for driver software > then go to usb_drv_windows folder in OS_HACKING tool then press Next. Wait till the driver installs.
After that, run the AIO Tool and follow onscreen instructions. You should now be able to enter Fastboot mode and flash your phone.

Dear Bro!
I've flashed, unbrick, made my Lg p920 dualboot several times before but now I have problem and need u advice.
Yesterday, when I was playing a game it suddenly turn off, and turn on to the lg logo and go off. At the first time I just think its the error came from the game so I tried to press power button to turn it on but no success.
After awhile I plug power cable in and the phone turned on and boot smoothly in to the ICS, but this time I realize that power button is not function anymore.
Up to now, My phone is:
Power button dont work.
If I want to turn it on I must plug the power cable in and It boot completely to the ICS(when I put in battery the phone is wake up and boot to lg logo and go off).
I tried to install Omap driver several time but no success, There isnt Lg United Mobile port in device manager to change the port to com41.
I cant boot in to flashmode to flash but can go to TWRP (via a software in android - restart to TWRP option)
My power button physically situation is good (I mode build.pro to wake my phone up by camera button 2 years ago and it work well up to now with no problem) Therefore, I think the problems should be errors in bootloader or kernel , xloader so I think if I could flash them via TWRP may be solve.
Could u please help me?

My power button physically situation is good (I mode build.pro to wake my phone up by camera button 2 years ago and it work well up to now with no problem) Therefore, I think the problems should be errors in bootloader or kernel , xloader so I think if I could flash them via TWRP may be solve.
Could u please help me?

XDA member Zogu made a thread quite a while ago. Here it is:

There you will find Wkpark's bootloader as a flashable zip that you can flash in TWRP. You said that you are an experienced user so I take it that you can also find and flash a kernel compatible with your ROM.
To be honest, from your description, I don't think any of the above will help you (but you can try, if you want). I believe that your power button is stuck to "pressed" state. If you could spray it with some contacts cleaner while repeatedly pressing and releasing it, you might get it to work again.

Hi guys
Does anyone know what is the best course of action to revive an lg p920 running stock ICS and died after twrp 2.3.3.0 was flashed via twrp manager from the market.
The screen went black and phone completely dead now.
I just ordered a factory cable on eBay and wondering whether to flash kdz or is there another fix that I can flash to revive it?
Cheers..

Solved
Even with factory cable, windows 10 PC was my problem.
I flashed kdz on a different PC running windows 7 and all is working fine.

Lg g Stylo, "no command" please help me!

Please guys I need your help!
Phone model: Lg G Stylo h631 T-Mobile version.
Today I was using my phone and after finishing a call, my phone started to update itself. Then I received a error message. After that, I get stuck with a dead android guy on the screen, and I get the message "no command". I try Different combinations of buttons to solve this problem: Volume Down + Power release and then press the buttons again went the LG logo appear and have no luck. Then I try Volume Up + Power, also have no luck. I think I try almost every possible combination an nothing is working.
If anyone has any idea how to solve this issue please help me. Any help would be appreciated.
(Sorry for my bad English)

Make sure you download or have downloaded and installed the LG drivers from the LG website or any other reliable source or your phone will not be able to recover.
Unplug the phone, take out the battery and once the phone is completely off, replace the battery. Keep the phone powered off and unplugged. Plug a data capable (the usb that came with the phone is best) usb into a PC. Press the VOLUME UP button and HOLD it WHILE plugging the usb into your phone, (The PC should already be connected before plugging in the phone) continue to hold the VOLUME UP button until you pass the LG splash screen and you should then be in DOWNLOAD MODE. From there you can reflash the stock ROM that came with the phone. The stock ROMs are pretty easy to find here on XDA.
If you don't know what flashing a ROM is or means then XDA has plenty of guides for that as well. To return to stock you will need the LG Flash Tool or LG UP depending on which version you want to flash. Marshmalllow uses the LG UP program and Lollipop uses the LG Flash Tool. You can find guides and all the tools\software you will need to fix your phone right here on XDA or a little Google searching.
