Hello all,
I just rebooted my phone this morning and my phone appears to be in a hard bricked state now. When I plug it in, I see that it comes up as QUSB_BULK_CID:SERIALNUMBER and not sure how to recover it. I did some searching and it seems like you need the proper firehose, but I'm not familiar with these methods of recovery, only TWRP. My device was completely stock, no root and the unlocked USA model (LM-G850QM). Any help would be very appreciated!
Got the phone to restart. I left it for a while, unplugged from computer, held down POWER + VOL DOWN + VOL UP and then plugged in, the LG G8X logo came back.

Hello there. My device is LG Optimus Chic E720, and a couple of days ago, I installed ROM Manager and downloaded a random ROM. After the download was complete, a window came out and I clicked on "Backup current ROM". After that the phone restarted and entered in fastboot mode with a black screen and an inscription saying: "Fastboot mode started udc_start()".
I looked around the internet how to remove that and i found this tutorial: http://androidforums.com/optimus-m-all-things-root/382525-guide-get-out-fastboot-mode.html and i did it step by step and it worked. The phone got out of the fastboot mode and rebooted itself. But after that the LG logo came out for 2-3 secs and the phone rebooted again and again. I plugged in the data cable so that the phone wouldn't turn off and pressed vol up+vol down+power button and it entered in emergency mode. I couldn't do anything. I looked around the internet again and i saw this thread http://forum.xda-developers.com/showthread.php?t=1060121 and decided to try it. I did everything it says, except that in the "phone mode" menu, i chose "emergency", because my phone was in that mode. So I started the software update and everything was going OK until it stopped updating (or at least i thought so). It just stopped, the phone went off and that's it. Now it doesn't want to turn on. It's practically dead.
I am asking you guys, is there any chance of me bringing it back to life and how ?

Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?
I've seen a few other similar threads, so apologies if you think I didn't search. But all those other threads appear to be with a rooted phone. This phone was not rooted or modified in any way. It was fully stock from T-mobile.
It belongs to my 12 year old daughter. She is not technically savvy, so I believe her when she tells me she wasn't trying to root it ("What's rooting?" she said). Here's what she said happened:
She was at a friend's house. Used the phone until the battery died, no abnormal behavior by her or the phone before the juice ran out. Went to plug it in, the greyed out battery with a loading indicator came on the screen as soon as she plugged it in, and a few seconds later, the LG boot logo appeared. It showed for approximately 10 seconds, went to black, and then started the LG boot logo again. It's been in that boot loop every since.
We have to pull the battery to turn it off. The battery and SIM card have been pulled for hours at a time. I tried the hardware keys to get to stock recovery (volume down + pwr. Wait for boot logo, release and press power while still holding volume down). Recovery will launch, but as soon as I choose the restore option, it goes back into the boot loop.
Tried the many-times-posted sequence to flash stock recovery. When I hold volume up and insert the USB, the initial screen for download mode shows up, stating to keep holding volume up until you see the download screen. After about 5 seconds or so, it starts the boot loop all over again.
Only thing out of the ordinary was applying a recently pushed update from T-Mobile.
Here's a link to a video showing the loop, the recovery mode, and download mode: https://youtu.be/eRmXqFoz5iY
Even though the phone is under warranty, T-Mobile wants $20+shipping to replace it. I'd like to try to fix it before I pay them for breaking my daughter's phone. Any help is greatly appreciated.
Long story short my V521 is bricked, as far as I can tell.
Here’s what happens:
Turn on.
Shows ‘can’t detect corruption’ unlocked boot loader screen.
Shows LG screen.
Reboots.
If I attempt factory reset via hardware buttons, I get a Nougat circle that says ‘Erasing...’, then reboots into the above loop.
Download mode seems to be nonexistent, as it just never works. My PC does not recognize it as the right device for LG support tool or Uppercut to find it, despite all drivers being installed.
ADB was working until stock recovery flashing (which I thought was gonna be a fix...)
And now I don’t know what to do.
Basically, the only thing I have is an unlocked bootloader.
Someone. Please.
Help me.

Try:
1. disconnect usb cable and power down your device,
2. hold vol+ button and plug in usb cable
It should boot your device into download mode.
Hello,
I had my Oukitel WP 10 rooted from One click root, it was working just fine, then about a month later, the phone was acting weird, ( going slow). I rebooted the phone and waited for it to turn back on...well, it didn't do anything. I tried putting it in recovery mode, and pressing and holding power + volume up, nothing. I tried power + vol. down, nothing. I had it charging it all day, and tried everything again, nothing. But, if I have it plugged into the computer. It beeps, then I unplugged it, then it beeps again, so the computer detects it. I tried to get One click root to help me with it, they said they can't help me, and to try somewhere else.
So, if you can, please help.
