After a busy day, My phone Charged down to 1% I have put on charging and after 5% i pulled the charger out. Put an alarm and slept. After waking up in the morning I saw it was Off, I tried to Charge but red light didn't respond. I tried to switch on, the screen blinked black light for 2 seconds. Later I have tried pressing Home+Vol Up+ Vol Down, I have tried Recovery mode and Factory Mode it turned off after blinking for 2 seconds. Thats it and dead. Now no response from phone even I charged the battery from another phone and put in this. There is no screen blinking from then Onwards
I tried :
Flashing with SP Flash but when connected to PC It is not detected as Mediatek Driver 'USB Device Not Recognized' In Device Manager it shows 'Unknown USB Device' Port Reset Failed. Re installed Mediatek drivers and tried VCOM too. nothing worked.
Last year I have updated to Lollipop officially connecting it to wifi and selecting 'Software Update' in Settings. From then USB is not detected whenever I connect PC, It only charges the phone there is no option of USB Mass Storage. So I have never turned on USB Debugging option.
I never:
Tried to Root, Flash or Change ROM and any Software related works.
Please help me in this issue. How to Recover It. How to Flash it and Install any Lolllipop firmware without losing Phone Storage Data (If possible).

If you did not do any software related work, you bootloader must be locked. Which means you cannot flash any ROM by yourself. The only thing you can do right now is to hand it over to the service center. There is absolutely no other way.
But such a case is absolutely impossible if you are not rooted. If it is still under warranty, exchange the phone. Or your phone must have been refurbished at some point of time.
my problem
Is there any other way that can we do anything by ourselves rather than giving it to service center

Ok so I am trying to install ICS on my LG925 but I have a problem. My phone seems to be stuck in download mode. When I power off the phone the only way I am able to reboot it is to remove battery, plug usb into wall jack, plug usb into phone, hold volume up and power insert battery. When I see the lg logo I remove USB and the phone boots up. But like I said everytime I power down the phone I must go through this process. Already tried factory defaulting but it made no difference.
I am using lgmobile support tool to restore phone now. I believe I have already tried this without success though. The phone updates without a problem, but when rebooting the phone remains in s/w upgrade mode. (at least I believe that's what mode it's in the screen remains black but it does communicate with the pc.
After finally getting through the ICS install correctly my phone is now booting properly again. Nice to finally have ICS now to find and apply all the bug fixes.
Hi, its been almost half a year now since i bricked my O3D, im still having problem solving this. I'm still newbie at this so i dont how to solve it. Still stuck at where you fastboot the omap thingy. I cant get into download mode i've tried all sorts of ways and still no luck. Did install OMAP4430 and after that the fastbooot one, tried holding vol+ and plug the cable and no logo appeard on my screen its pitched black only the search/back/home/menu buttons lights on. Then after a minute or less its turn off and the OMAP4430 in the device manager started to appear and disappear all the time, also i cant seem to find the LG port device on my device manger Help?

for pc driver installation. It is rather fiddly, so proceed slowly and read all details carefully. Once it is correct, however, you can use LG Flash Tool, Fastboot, ADB, or whatever for this device.

did all its says from the top still i cant find the LG port and my device manager keeps on refreshing and the OMAP device also keeps on appearing and disappearing.
Btw i did went(last year ago) to LG costumer service and after a week they said that the main board is the problem, and it cost more likely 40-50% of the original price of my phone Up until now im still hoping for my phone to be fixed.
I would try again; there are a lot of little details there that are easy to miss the first 5 or so times trying to do it. Rebooting pc between each step, for instance. You must be logged onto pc as administrator also. It took me some time before I was able to install the drivers correctly and that was before I wrote it all down in detail.
If it really is the board (I picture a scenario where they want to sell you a new phone) then none of this will help. However, the omap4430 blinking on and off tells me it is trying to connect, but is not installed correctly.
Take your time with each part and carefully check every detail.
omapboot and sw are two different modes.
the "LG port device" appears only in sw mode
omapboot:
you need omap for flashing the custom bootloader
enter the mode: remove the battery and plug your phone to usb while holding vol +, for me its working also when i just plug the phone without battery. if the device is appearing to fast in the devicemanager plug the battery into the phone, and the device should stay and you can install the driver,
sw mode:
is needed when flashing wit lg flashtool or smartflash etc for flashing stock roms or simliar.
you can enter that mode:
plug your phone to usb while holding vol+ with battery insert, and keep holding until the phone screen shows sw and some korean letters.
now you can set the port to 41 in the device manager

yes, in the sw mode, thats where i got stucked did hold vol+ w/ and/or w/o battery (tried both) no logo and korean letters appeared on my screen totally pitched black only the search/back/home/menu lights up after that the omap keeps on appearing and disappearing. Tried different cables btw im using win8 and i also tried fresh start on other laptop's of my friends. It's very frustrating
anyone had some success here? I have as well OMAP device on-off, I can go to SW Upgrade mode (no Korean letters though) and to stock recovery.... Tried LGFLashTool2014 (but it crashes on "Read Phone information) and "Flashtool"-Tool, which can enable fastboot and flash uboot, etc. But to no success...
Received an OTA notification and installed. At last check, was at the "updating apps" stage. Went to bed. This morning, nothing. Won't turn on at all. Was plugged in all night. No splash screen, no vibration, nothing. Totally dead. Power button + Down button doesn't work. Any hope of recovery?
Update
Also getting - unknown usb device (device descriptor request failed) / code 43 when trying to plug the phone into my computer.
Did you try holding volume down and connecting phone to computer? Try disconnecting the battery for a few minutes, reconnect the battery, and try to power up.
If for some reason it's an issue with the bootloader, there's a backup bootloader, hold vol up + power
Also something to try is LGNPST, that can reflash stock firmware
Power button+volume down doesn't work? The device might be fried. That might also be why your PC doesn't recognize your phone, although the very fact that your PC does recognize that there is something trying to connect to it, makes me doubt my hypothesis.
I'd try to adb reboot it, I think the phone doesn't have to be turned on for that to work. Are you familiar with adb commands? That way I was able to revive my old HTC that was stuck in bootloop and volume buttons didn't work so couldn't get into recovery. Just turned off the phone, plugged into the PC and adb reboot recovery or something, don't remember the exact command line, but you can find guides about it easily.
damn ! i have the same problem after the last OTA update
Maybe it's volume up while inserting the USB cable? Can't remember as I haven't used a nexus 5 for months.
My phone bricked dead, It won't respond to anything, won't turn on and won't show it is charging even!
When I connect it to pc thro usb windows shows a device is connected then says "device is not working properly"
and every fast boot shows "waiting for device"
I tried everything, I don't know what to do.. can anyone help me please?
Thanks
Reinstall the pc drivers and try to put the phone in bootloader mode (press power+volume down for roughly 3 seconds.) If the phone doesn't boot into bootloader (fastboot) mode, I'm afraid you will have to send it to moto (as fastboot flashing firmware is taken as last resort).
Edit : You sure the usb port is fine? It might have been that the usb port got damaged and now the battery drained out.

I think usb debuging is off... Thats why computer not recognizing....

Your phone won't turn on? How do you expect to show on your PC if you can't even turn the device on? It sounds like either the battery or USB port is bad and the battery died so now it can't charge... Assuming of course you tried the normal stuff like cables, chargers, different ports, etc.
Similar thing happened to my phone I kept my phone overnight charging and in morning I tried to go to bootloader mode It took about 1 min to go to bootloader mode then after going to bootloader mode go to twrp recovery and reboot system and you are done remember try this whole process on charging your device if doesn't work still you will have to give it to moto hope it works
if your device is not responding when you press Power button, probably is hardware problem.
so yesterday i was playing on the phone and suddenly the whole phone freezed and a strange cracking sound come from dthe speakers, i turned it of by pressing long the power button and it never turned on again.(blugged on a charger and try on pc if its recognice any qualcomn driver but nothin)
in the morning i tried again to charg but noting and i give a try on pc and suddenly a red led is started blinking after 3 hour it booted up and started to charge by 10%hour. (pc cannot recognize the phone while booted up)

it turned into a bootloop (with stock recovery and unlocked bootloader) and nothing can recognize it in fastboot .
Any advice??
