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.

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
OR try this one, since it really is a step by step guide
http://forum.xda-developers.com/showthread.php?t=1396091 I do not understand, I'm Brazilian.
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.
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.

Hi Xda,
Yesterday I tried to install cyanogen on my Lg l90, I rooted it and flashed my phone with flashify and tried to install the rom, but during the installation something went wrong. I got into a purple screen that told me that the installation was failed and a ''Ramdump'' occured. So I canceled the installation, but when I tried to reboot my phone. It didn't work. I can't get into recovery mode, download mode or emergency mode. Nothing works. But when I put my phone on the carger without the battery in it. I get an icon of a battery on my screen. And If i plug my phone into my pc, A removable disk connects with a capacity of 64 Mb. I don't know what it is, there are 2 maps on it. Verinfo and Image. If I open the map Verinfo I get a textfile with a number on it. The map Image contains 75 files. I tried everything, getting it back with Odin. But nothing helps. Can you maybe help me?

When pink screen ramdump appears hold power button to restart the phone, it should boot to android.
Then you need to unlock the phone bootloader, check this guide: http://forum.xda-developers.com/lg-l90/general/guide-unlock-bootloader-flash-custom-t2839690

Hello,
Today, while I was using my phone, it restarted itself and has been stuck at a boot loop almost entirely since then. It has successfully booted up 2-3 times but will usually restart itself within 30-45 seconds of booting and then will be stuck in a boot loop again. When it has started up its usually after it has been bootlooping for a while. I'm rooted and using xTreme Rom v2.0. I have had occasional random reboots here and there before but the phone always booted right up again without any issues. I haven't done anything with root/recovery since early September.
I've tried doing a factory hard reset without any luck. My phone booted up after I tried the hard reset and it was like the reset didn't happen. I can't boot into TWRP. I can boot into download mode and I tried to reset using kdz. It got to 100% but the the phone restarts and is back in the boot loop (then the lg flash tool gets an error and force quits). I've tried removing my sd and sim cards, I've tried swapping to a different battery, I've tried leaving the battyer out and letting the phone cool down. Nothing is working. I have noticed that when the phone is going to boot up correctly the full LG animation plays. When the phone is going to boot loop I only get a static LG Powered by android image.
Any suggestions?
Since I tried to rest using kdz I can't get past the boot loop...Device also isn't recognized when using adb
edit: It booted up once this morning and went to the initial set up screen, like the kdz worked. But about 30 seconds-a minute later the phone locked up, rebooted and has been stuck in a boot loop since.
That's weird..
So the KDZ goes through all the way successfully.
Phone does the update all apps etc.. and it still boot loops after a while?
Which ROM version are you updating it back to?
My phone just did the exact same thing. I'm also on the Extreme Rom. Everything you described is my experience too. When I use the LG tool it goes all the way through and reboots the phone but just keeps bootlooping. Did you find a fix? I've tried everything i can think of. Probably going to take it in tomorrow and get warranty on it.

I used the following method:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Download the correct KDZ file to flash back to and follow the rest of the instructions. You can also look at this video tutorial. https://www.youtube.com/watch?v=zXO2SHqBiNk
The one you'll want to try is "Normal Flash"
"CSE Flash" is a full wipe that deletes all data.
Mine was weird where it told me my phone disconnected, but the progress bar was still continuing. If that happens to you, don't hit cancel, let the progress bar finish to 100%
Hey guys
Samsung Galaxy Mini 5570 is a pretty old device now and definitely not worth to talk about, but It's for my aunt and she said i HAVE to fix it otherwise she will kick my butt.
This is the whole story:
Phone was running a very low android version (it was 2.1 or something) that i could barely install apps on it (Just installed WhatsApp), I decided to upgrade it to a higher version so i could install other applications like Line and Telegram for her, so basically i had to flash CWM file first because it was required, I flashed it using this link:
http://www.droidthunder.com/root-install-clockworkmod-cwm-recovery-samsung-galaxy-minipop-gt-s5570/
They said flash the cwm file and factory reset your phone but i flashed the cwm file and rebooted my phone without factory reset, everything was working fine :good: but i decided to follow the instruction so i rebooted into the recovery mode and factory reseted my phone (by my phone i mean her phone, but i'm gonna say my phone instead) and guess what, it never booted up again. stuck on Samsung logo.
But i could go into the download and recovery mode, so basically i followed this instruction:
http://www.droidthunder.com/update-samsung-galaxy-minipop-gt-s5570-android-4-2-1-cyanogenmod-10-1/
which is from the same guy, I flashed it using recovery mode and flashed gapps too, everything went normal without any errors. So i rebooted my phone and ............
a black screen poped up, I was really worried because i couldn't boot my phone, nor could i go into the recovery or download mode. I don't know if i could or not but the only thing I'm getting right now is a black screen or a backlight.
The only thing that seems to be working is when i hold Power+Volume UP button, my laptop can detect my phone (as Samsung CDMA Technologies) but can not flash anything using Odin, it stucks on "setup connection" message. Nothing else is working, I tried:
Home+power+volume down
Home+power+volume down+volume up
Power+volume down
Power+home
etc
I also tried a hundred different ways like completely uninstalling the drivers (with or without kies) pulling battery out, try those key combination while battery is out and reinsert battery while holding them but nothing is working.
I found this article yesterday which is for unbricking the hard bricked phones, but ADB can not detect my phone:
http://www.engineerthink.com/blog/2015/11/how-to-unbrick-hard-bricked-android-phone/
Please help me guys, And do not suggest me to take it in Customer Service because i would if i could.
Thanks in advance
