Picked up a used LG Volt from eBay for cheap, seller said device is user-locked. First thing I noticed is this is a Boost phone and there is a Sprint sim installed. Thought someone might have been monkeying with the internals. The phone is pattern-locked. I have tried every conceivable combination of button presses/holds and the device will NOT enter recovery mode. All I get is the LG logo coming on and the notification light glowing, then the logo and light disappears, then the logo comes on for a couple seconds then back off again and keeps repeating this cycle.
I connected it to my PC but, since I can't unlock the screen I can't set the phone as a removeable drive and it does not connect to the PC. I have installed the LG Drivers and tried to put the phone in DL mode, however, it is still not recognized by the PC. If I open up device manager on my PC and then plug the phone in the device manager rolls up and back down again like it is trying to figure something out, but the device still does not show up . I have installed/uninstalled the drivers and rebooted my PC several times in hopes that it would connect. I have tried a couple of Android managers on the PC but they don't recognize the Volt either. I have booted the PC into Linux and tried to work with it there but, again, it is never recognized. I have read several post concerning flashing in DL mode, even installed LG Flash Tool, but since the Volt isn't recognized the procedure comes to a halt. I read about ADB but I can't unlock the phone to set debugging and, I believe, the phone needs to be recognized by the PC.
If I could just get past the pattern-lock or get the PC to connect to the phone I feel I might have a chance fixing it.

Is there anyway to turn on usb debugging on a bricked lg optimus t ???
Found that on one forum
-> My Optimus T did the same thing when I was trying to do the official update from LG. This is what worked for me. Disconnect usb cable from phone. Pull battery. Restart computer. after computer reboots, leave battery out of phone and plug usb cable back in. Let windows install drivers. After drivers are installed, go into device manager and disable android modem. will not update if modem is enabled. It will say you have to reboot pc for changes to take effect, click no. log off pc and log back in, do not reboot. after you log back in you can get the software updater from LG and it will reflash your phone. Worked for me anyways. I thought my phone was bricked, but this saved me.

Like so many others, i've tried to flash an incompatible rom to my chinese mtk6589 1gb ram 8gb rom knockoff device. (bought on amazon, called newisland) here is the model no.: Alps 09_v89_jbla828_hd
I rooted it correctly, I have the correct drivers. I installed cwm recovery.
I believe I backed it up on mtk droid tools, but i'm not sure it saved correctly.
The first few roms I tried got stuck on a distorted brand page, but at least I was still able to access cwm on the device.
My current situation is as follows:
black screen, device doesn't react to trying to load cwm. When I plug it in, I get a red battery-charging light.
when I connect my device to my windows 7 64-bit computer via usb, I get the sound that the phone is attached. After about 10 seconds, it sounds like it is being disconnected, but it's not. Then it re-connects, disconnects.
I had uninstalled the vcom drivers through usbdeview, and now I am incapable of reinstalling them. The only indication in device manager that my device is connected is under “network adapters” where it shows up as “alcatel single rndis interface #7.” this alternately shows connected/yellow exclamation point corresponding to the connecting and disconnecting sounds of the device. The drivers and the device itself never appear in the list, not even for 2-3 seconds.
Trying to load the drivers independently leads to the message “inf does not support this method of installation.”
spflash tools doesn't show the device as connected.
My questions:
1. is the device a total loss?
2. can I possibly revive it without using the touch point method? (I can't seem to detach the cover even after I unscrew all the screws)
would appreciate any help I can get.
Please post in [Ask Any Question][Newbie Friendly] so that the right experts may be of help.
All I see is a google logo, not rebooting just staying on the screen. I am pretty sure I deleted the operating system, but I can't seem to get in recovery. What lead up to this was me not being able to connect the device to windows over usb, nothing in device manager, I couldn't even get adb to connect even through twrp sideload. But now I think I caused a whole new issue. I'm just trying to get back to stock rooted lol. Advise?
Edit: unpluged battery and replugged it in, got into recovery now, still having issues connecting so I can flash a rom.
Edit: I have the google usb driver installed from the android sdk. I still can't see my device in windows device manager nor I can't see it through adb. still searching around for a solution.
Edit: I found my old rom still on the device so I was able to install that to actually use the device. I still can't seem to connect to the pc in any way though. I have usb debugging checked drivers installed. Windows just doesn't seem to think a device is there.

Try toggling MTP and/or PHP in USB options.
Your device might show up as an adb device in Device Manager.

Use a different usb port, different cords, or even a different computer, until you get a pc to recognize the phone.
I had this. It was because not all USB leads have data. Even some that do are wired different. Use the original or HTC work fine with N5 as I've both brands

Well on my 4th cable, what do you know it works just fine. Feel a little silly but thanks everyone.
hi guys, (LG-P920 is my Phone)
yesterday i installed ROM MANAGER to install CWRMOD (or something like that).
Then i choose my Phone Type and flashed it. After that my phone permanent restarts in 1 second,
showing LG Logo and restart, restart restart nonstop.
I understand that i ****ed it up with flashing that recovery mod. So i decided to Plug into my PC
and install everything new, but when i connect my phone to PC , it detects a unknown device every second and does it permanently too. I tried the "Battery out, Volume Button UP and connect" trick, then it stops acting weird but my PC
dont recognise my phone as OMAP, it is just an unknown device
What should i do guys? i tried installing LG Support Tool, LG Mobile Driver, and i read all the Instruction to UNBRICK your phone.
But all the Instruction starts with a successful regocnition of OMAP driver, but my PC dont even recognise it as OMAP.
PLS HELP
ok i fixed it, it was a really complicated move to 0.1 sec click that omap and install while my Phone was permanent restarting.
I have searched for 2 days now and tried countless fixes for this issue, even fixes that have nothing to do with the phone. When I plug my 7 pro into my Windows 10 desktop it is instantly recognized and I can access files. When I plug in my 8T I get "USB device not recognized."
It's actually more complicated than that though. I tried using a different cable, it worked for a bit. It loaded and I could access it. Cool. Went to the MSM tool to flash the global rom and right as it started going the phone disconnected and the "USB device not recognized" error popped up. Now the phone is bricked. Black screen, doesn't vibrate when I plug it in. Can't unbrick it with the MSM tool as it's not a recognized USB device and isn't connecting with the computer.
Tried connecting it to my Samsung Galaxy Book 2. Same thing. 7 pro is fine, 8T isn't recognized.
I have tried removing and reinstalling drivers. I have tried unplugging the computer and all cables. Tried several other things. Searched youtube, google, duckduckgo, this forum, oneplus forums, and asked at r/oneplus and got no reply from anyone.
Can this be saved?
Update: Connected another OnePlus 8T to my computer and it popped up an option to install drivers from a cd that doesn't exist. It seemed to think the phone attempting to install drivers was coming from a CD. Never could get it to work, used the .exe file I already had and installed drivers and now that phone is recognized and I can access the files. This never happened with the other phone. It was errors from the start.
