[Q] Still have the stock rom, why did my phone stuck? - LG Optimus Black

Hi, first of all I must say that I never used any custom rom or flushed my phone yet. I still use the stock rom provided by LG. So I was typing a text a message today and suddenly phone locked and I couldn't do anything. I clicked power button and pressed again to get the main screen but some part of the screen was total black and some part was just fine(still I can't do anything btw). So I just pressed power button longer to close; I could close it but then when I tried to boot, I just got stuck at LG logo and it's still the same(30 minutes passed!!!). How about that? What should I do?

Remove battery.
Wait 10 seconds.
Then put battery back and turn it on again.

I just did it; over 3 minutes passed and it's still stuck at LG logo!!

my advice alhough i have not worked with lg phones would be to reinstall the stock rom. i am unsure from your post if you were using a custom rom when this happened when you bot the phone if its like the htc phones you can hold the voldown and power buttons to get into what is essentially the bios of the phone i hope this helps

Then, connect the phone to the usb in a windows computer.
Run the LGMobile Update tool.
Go to the menu Customer Support/Recovery Phone
Follow the instructions there.

I connected the device via USB and opened the Recovery Mode in lg mobile update tool, but it doesn't recognize my device. I already installed usb drivers and they were working correctly couple of days ago. What else I could do? Any help would be appreciated...

hi! How about hard reset?

Well, it seems like I have to do one, because I fell that it'll never come back so where should I begin for a hard reset?

Remove battery
Put it back
Hold Volume Up.
While holding, plug in USB cable to computer.
Your screen should say S/W Upgrade.
Run LGMobile Update.
Customer Support/Recovery Phone.

I did exactly what you said. It could successfully update the phone, it's still stuck at lg boot logo. So the next thing I should do is a hard reset?

After what you did, it could take a few minutes to start, that is normal after rom changes.
I'm not aware of a 'hard reset' for the P970, beyond what you did.
I think this could be an indication of a hardware failure.

Bricked p970

Hellow!
Today i have a Custom Rom to my Black.
But when i flash this, and press reboot in CWM the mobile turn of, and never never can turn on again.
I tried presisng vol. Up, but doesn't working.
Any ideas?
are you sure that ROM is for the Optimus Black? where did you get it from?
Is a SuperTeam ROM.
but in other way.. rom's can't kill mobiles...
Send me the link for the ROM.
http://db.tt/DNETBI5
No wonder it's not booting, you flashed a ROM that is not adjusted to P970.
I suggest you follow the repair tutorial (connect USB while holding volume up and without battery - you don't need the power button).
It should work. If it doesn't, well, you should go switch it at the store.
This rom is maked to p970! I'm SURE!
Other problem, for understand this.
Now when plug USB / AC to my black, doesn't appear battery caharging image, screen is black, and twho hours ago when y conect mobile(turned off) in screen apears a battery, but not now.
Now, you understrand more?

The ROM is made for P970 but it's not adjusted to it.
There's a difference.
Try this:
http://forum.xda-developers.com/showpost.php?p=14570674&postcount=21
Isn't perfect, i know, but i don't know why when I flashed my p970 dies.
I tried ALL tutorials in XDA or other forums but the problems is.. that i can't turn on mobile in S/W Upgrade mode, you know?
I press and conect via USB but p970 do nothing!
It is very strange. Are you sure that you're doing it right? It is so easy.. Remove the battery, but don't insert it again. Without the battery you press vol up button and connect the computer to the device at the same time you press it.. You'll see s/w update screen
You thing that I'm idiot, no?
Sorry.. but i tried more than 20 times this combination.
Tried Vol. Down + Power too... and nothing works.
The only way is going to store, nah?
Yes I think you are. Someone that isn't able to just press vol up while connecting pc-lg without battery, that ask others to try a rom that bricked his own phone and that is talking about combinations and power when the only combination is vol up while connecting the device ... sorry but you'r not thinking right
Well try again.
Quit battery -> Done
Press Vol. Up + Conect to PC -> Done
What hapen? Nothing!
Do you have the lg mobile support tool and lg p970 drivers installed?
Okay, I cannot boot into s/w update and no battery charging indicator.
I haven't other solutions!
It's bricked mate, you have to switch it.
You don't have to have the battery out to do this.
I bricked my phone by accidently uninstalling the launcher without having another and i did this method with the battery in and it worked fine. You have to have the LG Mobile software installed though.
I accidentally uninstalled the launcher as well. And the phone is bricked. Did i happen to find a solution to that ?

Phone Stuck: Weird Problem

Hello Friends,
Dont know what the hell is this, but it is totally weird.
Actually i m using NOVA Rom 3 and it was running pretty good on the device.
I m browsing the firefox and checking laptops on ebay.
all of sudden my phone hangs, i wait for few minutes but nothing happened.
I pulled off he battery and restart it, but it stuck on the booting (LG Logo) and all the buttons were flashing.
I decided to restore the backup and tried to boot it into the CWM by pressing the G key, (i always use the same method to boot in to recovery)
after many tries, i plugged it into the PC via USB and boot into the firmware upload mode (by pressing the volume up and insert the cable into USB)
i tried to flash it with the KDZ Tools, it says 100% done but i cant boot up the fone.
Please guys tell me what to do,.
And i think LG will not giving me any warranty as the phones is rooted and i was using a custom firmware
Thanks
I want to know a thing
My fon is not booting, i tried every method.
So how LG guys will know that my phone is rooted and i installed a custom firmware?
Or they just checked it after the repair and then charge me?
May be some one will solve this query..
Thanks

[Q] O2X not detectable on PC and Cannot access to Recovery mode

Hi!
My phone is no longer detectable on my PC via USB (Win7 and Linux), with adb or nvflash with vol+ + vol- or vol- + power or anything.
This problem come from the last official stock update, like what, it's crazy. And no access to hidden menu, etc.
Then, after, trying to solve this problem by applying http://forum.xda-developers.com/showthread.php?t=1981359, by using Rom Manager to replace TWRP by CWM recovery (I know, it's very bad idea...), now my phone don't want to boot in recovery mode, I probably corrupt my system.
Now I have a brick, which can boot and display "S/W Upgrade Please wait while upgrading..." with vol down, but no usb IPX mode or adb or anything (to be sure, I try with another android phone, and work perfectly).
In normal boot, I have LG logo, then rom logo (an X in color), and no change, this animation continue but no end.
I had try many usb cable, reinstall lg drivers and nvidia drivers, different pc and os...
Can we restore recovery mode with special scheme, file, on a sdcard only by boot the phone?
I'm very interested in any ideas that can unlock me.
A big thank you to the community!

Yes, this script only call nvflash with predefined parameters.
My phone is not detectable by nvflash or adb, that is why it doesn't work.
Peace. :highfive too
I had a weird brick with my 2x too, after flashing a wrong rom and it was not working at all
So I decided to remove the battery and use a spare one I had in my stuff, and the phone turned on, and when i turned it off again I could reuse nvflash to get back to stock
Did you try something like that, or only charrging the phone for a few hours to see if comes back ?

I don't try another battery, but I have charging the phone with the official lg charger during 4 days, and nothing... This why I asked if we can boot or reconfigure with a "magic" sdcard...

Remove battery.
Press and hold volume- key.
Connect USB cable.
Still press volume- key.
Release when you see screen says "S/W" download.
Insert battery back.
If it worked use smartflash to flash a rom. If the screen still black, then you should try it on another pc. There is no way to screw up the nvflash mode with a bad flash or anything. Keep in mind that keys can be unresponsive during the years. It is realy hard to set my phone to nvflash mode since my volumkeys are unresponsive. I have to press them so hard that my phone nearly break in to half.
If it still not works change usb cable. Check the device manager for devices with a ! in a yellow triangle. If you see that you have some kind of driver issues. If all of these fails to revive your phone, then your phone is dead.

Thank you!
unfortunately it doesn't work, try with a new pc and a new cable... no change. My usb slot in my p990 is probably dead. what is infuriating is the rest works well.
Did you use fast charge with any ROM ?
USB fast charge can damage the USB connector
Did you try using the method to check if the device connects to computer with nvflash, since it does not require battery ?
Try checking this and if the USB connection broke you can send your device to a repair shop to replace it, or even search ebay, aliexpress and etc to find spare parts, and if you do so, I recommed get an extra battery (non original batteries are cheap)
good luck

That is probably a myth.
Try to use a very short usb cable and use the ports on the backside of the pc ( not a laptop!), I always had problems with the front usb ports.
SO I really dunno what could possible made this device die
I nevr had big issues with mine like this, but the closest thing that hapenned when the device stopped working, and did not charge, was to put another battery and this helped
is someone selling this the whole USB flex hardware? I wanna buy it. I am from Philippines.

Never seen this kind of brick before

So when I installed the TWRP app on the google play store and started it. It required me to rewrite my sd card or whatever so I went and ahead and did it. While my phone turned off still plugged into my computer via usb it started spamming the format windows on my computer. Like roughly 12 tabs opened up asking to format this drive. So I closed all the windows and re plugged in the usb and the same problem came up. And awhile all of this is going on the device is on but the screen is black and the back lights are on. Even when trying to restart the phone its the same problem stuck on black screen and the formatting windows keep popping up. It won't go to download or recovery mode it just stays on the black screen. This is my 2nd lg g2 I bought for business and I don't recall ever having this problem with my original LG G2. Anybody have any experience with this or a fix?

Yeah I've tried but the lg flash tool will give a error in the middle of flashing it
saying the phone is disconnected from pc, even though its still connected. It would go up to 25% then 60% then back to 25% in the middle of flashing then the error pops up.
Edit: Yeah while flashing the vs98024A kdz it will stop at 60% on the lg mobile support tool and it won't go past that. It'll just have the phone being disconnected from the computer error.
Is it safe to assume nobody knows how to fix this?
Same exact brick here.

Suggestion, have you tried the tot method yet? There isn't a 24A tot, but you can always take the ota.
same thing
I have the same thing and got it the same way with goomanager .was installing recovery and after reboot I got black screen with backlight on but to logo no nothing... can't get to download mode because I can't power off the phone. I also get the format drives promt in windows (about 15 or so all with a different drive letter) one drive I can read and it contains a folder called image with files in it. that drive is write protected. at this point I will wait till the backlight kills the battery and hope I can get into download mode after it shuts down.
FYI: I did try the LG mobile support tool but it did not see the phone. would love some ideas....

instead of waiting for the battery to drain, try this:
1. Unplug the phone from charger/USB cable
2. press and hold the power + volume down buttons for a few seconds... let go of the buttons 2 seconds after you feel it vibrate.
3. hold the volume up, and connect the phone to your computer.
you should be in Download mode by now....proceed to flash the phone back to stock using the LG Flash tool.
Hope this helps.

My wife has the same phone .. is their a way to copy her working files to the bricked phone?
Windows see's the phone as QHSUSB_BULK in device manager if that helps any. before all this started it saw it as an android device

I believe I have soft bricked/hard bricked my LG G4 h811 . Can anybody help me?

Okay so I'm a newbie to rooting. And I was on this step where I let the tool install some files to my phone and it said to unplug and pull battery, the next step said to hold power and - volume down button and release power when I see the LG logo while holding the - volume down after a second quickly hold power and - volume down to access factory data reset and settings. So it restored my phone back to factory settings and no root, the video said to try again but the problem is that my phone will power on anymore and is unresponsive when I charge it. So I took the battery out for a min. and the phone turned on but got stuck on LG logo and freezes then it shut off. I tried to boot it up again on LG logo screen, the corner it says Secure booting Error
Error code: 1009
MODIFIED!
And it froze and shut off. Now whenever I try to boot it up it gets stuck on LG screen and shuts off or when I'm in factory reset it freezes when I press yes. I put it into download mode and try to install the LG G4 stock kdz file but my computer couldn't connect with my phone for example, I plug my phone into the computer via USB but nothing, no sound and no charge now it won't turn on at all. I hope this wasn't too hard to understand and I'll greatly appreciate any kind of help, thank you.
.
I wonder if LG or T-mobile is pushing an anti-root tool that hard bricks the devices. My device was working fine until this morning after my alarm went off - Mind you, I have been rooted since the root came out. I unplugged the phone, put it in my pocket, and it got really hot, then it does the same as yours; except, my phone shows bootloader:unlocked when i try to reset it. So, yeah, you are hard bricked. No recovery from what I hear. U got a paper weight. I do not believe any of the G2 or G3 fixes will unbrick our devices. I think it may need a jtag.
