Optimus P990 Does not boot - LG Optimus 2x

I am running the latest version of CM10 for LG Optimus X2 P990.
The phone froze about an hour ago and I couldn't restart it so I decided to remove the battery.
After doing so the phone refused to boot at all! It can not be powered on at all, only if I have the charger plugged in and even so it shows only the LG logo and then restarts again.
I thought it was a ROM issue and tried to do a factory reset but I cannot access neither the recovery mode nor the software update mode.
In each case it shows only the LG logo and then either powers off or restarts.
I don't have any ideas left. Please help.
Thank you.

Try this to restore your device (you'll lose all data, except that on the external SD card).

Thanks for your help.
That worked but only for a bit. I can now see the softare upgrade screen but the phone still does not start.
It shows the LG logo and then restarts again.
I tried using SmartFlash after NVFlash fixed the softare upgrade mode but still nothing.

How can I check if my internal SD card works if I can not even power up the phone for more than 2 seconds?
I am not familiar with the KDZ upgrade can you share some help?
[EDIT]
Tried upgrading via KDZ file but the methods I found online (using the B2CTool and the KDZ_FW_UPD.exe) wont work.
I'm open to new suggestions.

I have a somewhat similar problem...
Got a P990. When I tried to tun it on, it just showed the LG Logo in White and right after that an Empty Battery with an exclamation mark in an triangle. I figured its deep cycled or something and tried to charge it on a computer with the usb cable (was in school, so no charger available). It showed the battery for quite some time (maybe 30 Minutes?). And no reaction to any button whatsoever. The phone got pretty warm at this state. I removed the battery tried to boot without it, or get into a recovery. Nothing.
Since then, the phone is even more dead.
No reaction on the screen, purely black, no backlight, no matter what I try.
Not recognized in NVFLASH without battery and the official LG restoring program does not detect it when trying to do an emergency restore.
No reaction on the pc, tried two pc's and three different usb cables with and without PC. (no new device found, nothing in device manager)
I got the phone, and I do not know what happened to it before, but no water damage and the mainboard looks fine (reseated all connectors inside).
I got about 2,4 volts from the USB cable on the battery pins, without a battery connected, by the way.
Should I try a macgyver charge like it was done on a defy http://forum.xda-developers.com/showthread.php?t=892026?
Any help?

I have the same problem. I tried installing cm-9.9.9-JB-p999-2.zip file by copying it on the internal card (not external SD card). The phone rebooted itself and now stuck at LG logo, doesn't move anywhere from there. Shutdown and rebooted still the same. I tried the following procedure .... Can someone please advise how I can fix that.
Thank you.....
Copy the CyanogenMod 10 ROM and the Jelly Bean GApps package to your phone’s external SD card.
Switch off your phone.
Reboot your phone into ClockworkMod Recovery Mode. You can do that by pressing and holding down the Volume Down key and the Power button simultaneously until recovery boots.
Create a NANDroid backup of your current ROM. From the main recovery menu, select Backup and Restore and select Backup on the next screen. Wait until the backup process is done.
Go back to the main menu and perform a full wipe:
Select Wipe data/factory reset and confirm the action on the next screen.
Select Wipe cache partition and confirm the action on the next screen.
Go back to the main menu and select Advanced. From there, select Wipe Dalvik cache and confirm the action on the next screen.
Go back to the main menu and select Install ZIP from external SD card.
Select Choose ZIP from SD card and locate the cm-9.9.9-JB-p999-2.zip file. Confirm the action on the next screen to flash the ROM to your mobile phone.
Return to the main menu and flash the Jelly Bean GApps package in the same manner as in steps 6 and 7.
Go back to the main menu and select Reboot system now to restart your phone.

[Q] Constant Rebooting after trying to flash to gingervolt

After trying the update(made cwm backups btw) the phone is in a reboot loop cycle. However, I can't get back into CWM in order to restore the backup i made or even the revo_stock or the stockrooted zip. I can get into the OS to the point where it wants me to select a language then it tries to find the SIM and fails completely and reboots. If i pull the battery and try to boot from the power on the USB it will reboot to the LG logo then instantly reboot again... Ideas anyone?
cliffs:
-backed up in cwm
-tried to install gingervolt
-stuck in reboot mode
-cannot access cwm to restore
Did you wipe data both times MT said? Maybe try wiping again?
Did you try flashing from a froyo ROM?
Wiped date both before and after the flash of gingervolt. I was using the decrapped rom 1.1
I would happily go back and try to clear the data again, however i cannot access CWM in order to do so after the gingervolt flash... Even using the power button+volume down i get no access...

I had the same thing happen to me. Although once it rebooted i was able to bypass the setup process and just manually do it from the home screen.
If you can't even get past the LG logo without it rebooting, I also had that happen to me on my last phone a few months ago. I called Verizon and they said that they had reports of other phones doing that too. Unfortunately I never figured out how to fix it. The problem was that it never stayed on long enough for the computer to recognize it.
Flashing Gringerbread ROMS from froyo breaks this phone. I did that same thing
restoring a back up is what you need how to get there idk
I haven't had much luck getting the phone to do anything, it will stay turned on for ~2-3 minutes then instantly reboot...

CWM reboot loop
Use this zip from thecubed it works wonders.
My phone would not go past reboot option in CWM
Search fast boot loop thread for further instructions on how to use it.
I pulled the SD card from my Revo and used it in my old win mobile Omnia so it would mount on my PC then I copied the zip onto the stuck Revo card.
Well after a few hours of tinkering i got her working... CWM never wanted to register but finally after about 100 tries of power on+vol it actually caught and booted into cwm. from there it was a cake walk until i got into gingervolt and it refused to allow the phone to come out of airplane mode(why this was even on is beyond me). after about 4 reboots the phone is working flawlessly...

LG screen shows up then black screen with blinking buttons

Hello guys!
I'm having some problem with my OB. This happened after one reboot while using TeslaLED's torch. My phone rebooted then the LG logo showed up. Then to my surprise, the nova8's boot animation didn't showed up. At first I thought it got bricked, but I waited for it to finish boot up. Then when I touched the screen, I felt a haptic feedback, meaning the phone ain't bricked.
Then I tried pulling battery and rebooting again. Same black screen with flashing buttons. Then after 5 tries of pulling battery and rebooting, it continued to boot to bootanimation and screen didn't turn black. But everything was wiped out. So, downloaded all my apps again.
And everytime I reboot my phone I get this black screen.
After a month of pulling and rebooting, I decided to go back to stock, to see if it was a problem with Nova8 ROM. And I hoped the issue will be gone after flashing back to stock.
But now, I'm on stock ROM. LG logo shows up, then black screen, then I waited and heard LG's stock bootanimation. Meaning it ain't bricked.
Can you help me? Is there a way for me to fix this? Any form of help will be much appreciated. Could it be hardware problem?
hi, I have the same problem that you've tried everything and I can not make my optimus black out the screen of lg. I've watched several people with the same problem.
Well, I can't say that it's good that you have the same problem. But now I'm sure that it has to be some problem with Nova8. And that it did something terrible with our phones.
I've tried flashing Cm7 rom and this problem doesn't occur. It could be a problem with Froyo Roms?

should always work. If not, either your phone is bricked and needs to be returned, or your PC doesnt work properly, or you missed anything in the thread, so follow it CAREFULLY, or you simply need more knowledge about your phone... so keep on reading

it is not bricked. I'm using my phone as I speak. It's just that its very hard to boot normally if I reboot. Because There's an 90% chance of getting into black screen than to continue boot up to bootanimation
yes my Ob also did not able to restart it if it was on the screen of LG, but now he does not care anymore.
Did you have CWM installed before? If yes get SuperoneClick and a custom .zip rom (e.g. redy's). And put .zip Rom to ur sd card.
1. Extract Superoneclick to C:
2. rename the folder to SO
3. then open Command Prompt by typing cmd into search/run or push windows + r and type it there
4. when command prompt is open type "cd so" without " "
5. type "cd adb"
6. type "adb reboot recovery"
7. wipe data, cache, in advanced wipe dalvic
8. go back
9. choose install zip from sd card and install the zip you just downloaded and everything should be fine, but ALL your data will be lost!
should I do the command prompt while the phone is connected?
Yes, otherwise, how should the phone get what the PC wants it to do? and also enable debugging mode if possible.
Solved it!
It seems that my phone has issues with Froyo based firmwares. When I flashed Zeus1 and CM7 my phone didn't showed the same problems I had.
What I did:
1.Used KDZ updater to flash V10A.(I came from Nova8)
2.When it's finally up and running, install Gingerbreak to attain root.
3.Download CWM recovery from ROM Manager.
4.Download any Gingerbread based ROM.(CM7,Redy's repackaged, Zeus1)
5.Put it in SD card.
6.Reboot to recovery
7.Wipe data/Factory Reset
8.Wipe cache partition
9.In Advance, wipe Dalvik Cache
10. Go back, Install zip from SD card.(Look for your ROM)
11.Wait for it to finish
12.Reboot.
13.Enjoy!!!
Why V10a? Because root can be attained using Gingerbreak. I tried Superoneclick , but got no luck.

[Q] Phone suddenly «wiped» / won’t boot

Yesterday I suddenly found my phone to be turned off by itself. When I tried to turn it on again, nothing usually happened. Sometimes however, it looked like it would turn on, but the white bootlogo would barely show, or maybe up to a second, and then it would go black again. When connecting a charger the charging icon would show for a second, and then black again, and still the phone wouldn’t boot. Recovery or download mode wouldn’t work either. I was hoping it was only the battery that had just died, since the phone won’t work at all without the battery, even with the charger connected. But when I tested a friends battery today, it would still not boot, and my battery worked fine in his phone. But, at least it turned on each time now, showing the bootlogo for a second, and then all black again. Recovery mode still won’t work, but I’m able to get it in download mode. If I connect the phone to the PC by cable first, it won’t start or go in download mode, I have to get it in dowmload mode first and then connect. I was using stock system v2.3.3 from about a year ago, but with Clockworkmod kernel.
So what could have happened? I figure the system is either corrupt, or even wiped?
Or could the phone itself be badly corrupted?
I also have to mention, that a few months ago the internal and external SD-card was suddenly wiped, and I got a message about error on one of them and had to reformat.
Since download mode is ok, I hope there is a chance to maybe flashing the system again with Odin?
Is ther any way to connect the phone to the pc and get access to the memory to maybe copy whatever data still there, if any? Or can I reflash to just put the new system on top of everything without formatting?
I think your sd connectors are corroded or damaged. For your data try to flash the semaphore kernel by Odin to get a recovery (link ). After flashing, go into the recovery look for "mont and storage" and select "mount usb storage" or something like that. With your pc connect your device and copy your data in your pc like an usb stick.
If it doesnt work, say goodbye to your data and try to reflash a rom by Odin
Link here
http://hotfile.com/dl/140301534/be8872c/I9000XXJVU_I9000OXAJVU_OXA.rar.html
Instruction:
- Unzip the file
- Open Odin (if you don't have it download here )
-Put CODE in the PDA case
-Put MODEM in PHONE
-Put CSC in CSC
-Now Put your phone in Download Mode and connect it
-Press Start and don't touch anything until the great case above the yellow one became green.
Please reply me for more info
Thanks, I'll try that tomorrow morning at work, don't have the time today.
At least I do have a complete backup from about two months ago, so it's no disaster about the data. There's not really anything that important on the phone, it's just all the work setting everything up like I want it again.
Please reflash a stock rom with odin...
I was able to flash semapfore kernel, but still I couldn't get the phone in recovery mode.
Flashed stock firmware 2.3.3 (last nordic version), and the phone booted fine, but lots of old programs kept crashing and messing with the system. Best of all, everything on the internal sd was there, so all the latest titaniumbackup was there. So I copied this to the PC, did a factory reset, flashed CF-root again, copied the titaniumbackup and clockworkmod-backup to the internal sd, and cwm-backup is beeing restored as we speak. Then titaniumbackup will be restored and everything should be fine for now.
I'll be leaving for holiday in a week, so I don't want to use lots of time right now to do a clean setup of the phone. There is way too much other things I have spend my time on before the holiday. But after the holiday I think I'll just have to do so.
Thanks for helping.
For your apps who crash you have to wipe apps data (with TB).
The apps crashing when I just reflashed didn't really matter since I was going to install the backup anyway.
But a few apps kept crashing even after I flashed the backup. So wipe app data was what I eventually found out I had to do.
And so the same thing happened again.
But this time it doesn't seem like reflashing will help at all.
Crappy trashphone, it's been a disaster rom day one.

The phone won't boot, and won't go into recovery mode, only download mode.
When I turn it on the boot logo only shows barely, and then nothing happens, just like last time.
I've tried reflashing several times using Odin, but this time it doesn't help, phone still won't boot. I've tried both without repartition, and wit repartition (and pit).
My friend got me to put his phone on cm9 after using froyo for a long time.
The strange thing was that the method to get into recovery suddenly changed from volume up, power and home. For some reason it is now both volume buttons, home and power ..
Just thought I'd share this since your recovery should work after a kernel flash.

[Q] LG P990 stuck at lg logo

Hey all,
I have a problem with my lg p990. At this time, I am trying to figure it out whether is a software or hardware problem. I have searched each and every forum to over come this problem but went in vain.
problem:
1) lg p990 shows lg logo and goes blank.
2) when vol down and power is pressed the phone goes to s/w upgrade screen.
steps I tried:
1) I have used smart flash to flash my phone to stock ROM.
a) downloaded the stock ROM and flashed with smart flash. The smart flash says process complete successfully and the phone restarts and shows lg logo and goes blank.
b) I tried to flash different stock ROM with the smart flash but same result.
2) I tried using the lg update tool (offline procedure since lg blocked it).
The lg update tool successfully completes the update procedure and tells
the phone will restart. The phone goes to restart and the phone shows lg logo and goes blank again.
3) Last but not least, I tried to download the custom ROM.
a) I downloaded the ClockWorkMod recovery by using nvflash
b) after successfully download recovery image, wipe cache/factory reset/wipe cache partition/wipe dalvik cache.
c) copied ROM in the root of the internal sdcard (connect the phone-->mount it-->copied the ROM and Kernel--> installed the package--> says installation complete-->reboot phone--> the phone does not get pass through lg logo and stays blank. I have waited for 30 minutes but no luck.
I don't know what else to do. After I tried all the steps, the phone just powers on and shows the lg logo and goes blank but the menu,home,search button still lights up. I also resetted the phone but still same problem persists....
Any help would be greatly appreciated otherwise I have a paper weight worth $350.00
I had the same problem as you face here.
I tried everything NV-flash, smartflash, you name it, no luck. Then I did a emergency repair in the LG updater.
Start the Updater, select "emergency repair", make sure drivers are installed.
Battery out, press Volume Down and connect.
Enter IMEI and S/N and repair program starts.
I had to do it twice, before it finished. I maybe had a bad USB connection or cable, but after "S/W update" showed up in screen on second attempt, I reinserted battery and it went very smooth.
Let it boot.
And then root with NV-flash and you are back in business with normal GB partition table.
I can recommend Tonyp's CWM 6.0.1.5 touch for NV-flash, when you have finished rooting.
It took me 45 minutes, with a not too good internet connection.
PS.: I did not try this one: http://forum.xda-developers.com/show....php?t=1715272
but since I could not call up NV-flash, I did not want to spend even more time trying.

[Q] Update to 4.2.2 failed. Phone not booting!!!

Hi all,
Last night, i rooted by N7000 through PhilZ-cwm6-DDLSC-ODD-5.08.5-signed and was successful in doing that.
Later i wanted to update my device to 4.2.2. So i downloaded cm-10.1-20130727-NIGHTLY-n7000.zip file and kept in my external SD card.
Then in recovery mode,i wipe the factory data. There was option wipe data or wipe to install new ROM. I selected the latter one. Wipe for installing new om was successful. Then i went to update zip.file option. But since the file was in external sd card, it was not detected and i was not able to select the file. Then i rebooted the phone but only 'Samsung galaxy N7000' screen was coming and nothing was happening.
I rebooted my phone many times but same screen was coming. Then in morning i went in advance options. I selected Recovery Bootloader. Downloading screen was coming and nothing was happening. Then i switched my off and trying to start in recovery mode but its not starting.
I thin i have no checked USB debugging.
Kindly help soon as i am helpless without phone. Your early response will be highly appreciated.
With the option "install new Rom" you removed your old Rom from your device. So it is only logical that your device won't boot into it.
Next time follow the installation instructions given in the CM-thread exactly.
And of course you can choose a zip from external sd card in CWM. So take a look again.
Best thing to do for you: boot into download mode, install a stock Rom with PC Odin and use it without changing things.
Hey Thanks for the help. But now i am facing new problem.
I flashed my phone using odin with stock rom.
Later i rooted with PhilZ-cwm6-DDLSC-ODD-5.08.5-signed and then updated it with cm-10.1-20130727-NIGHTLY-n7000.
This time i was successful. My phone was updated to 4.2.2.
Then i used it for some time and switched it off for removing the external SD card. After that i tried to switch on my phone, its not working.
Nothing is appearing on screen. I charged it and then tried to switch it on but nothing is coming on screen.
When i try to switch on my phone in Recovery mode or in download mode a thin line on the screen appears and then disappears and then nothing comes on screen.
Help please. Last suggestion worked.Kindly advise
