Hi.
I was trying to Upgrade my O2 XDA Exec Rom with Xda_Exec_Upgrade_v1.30.162. The process went successfully till 100%. Then I unplugged my pda from the pc and tried to restart the device. I was surprised that the device did not respond to any of the following
Soft Reset
Hard Rest
Boot Loader mode Start (Bulb + Power + Reset)
It is totally blank screen whatever you do.
When I connected the device to the pc with usb cable, a Red Light is shown for 2 seconds and then goes off and a message comes up on the pc that "USB DEVICE NOT RECOGNIZED".
Then I tried to Remove battery from the device for a whole night and the next day morning i did all the above procedures again to get no results.
Kindly Help me out
Thanks

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...
Hey guys,
I've seen some solutions for my kind of problem but none of them seems to start at my frustrating point.
After I rooted my HTC One S I was able to reboot my device and everything went fine.
The problem occured just when my battery was depleted and the phone got turned off I had no chance to restart it.
The LED did not show me it was charging and it did nothing, when I pressed the power button or the volume/power combination.
So i connected it to my laptop and tried to check my devices through adb.
It says my device is in recovery mode.
Using the fastboot reboot command I was always able to reboot my phone and everything was just fine.
I thought it was alright, as I just had to pay attention not to use up my battery, when not at home.
Today my phone just decided to turn off. It refuses to boot up even with the fastboot help from my PC.
It just says: < waiting for device >
certainly I'm unable to post a link to a screenshot I made of my cmd.
Thank you for all kind of help
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.
Greetings!
The tab is DANY GENIUS TAB G4.
The tab was rooted with KingRoot android app and bootloader was accessed. But it got stuck in bootloader. My assumption is that I may have selected fastboot mode by mistake. But nothing happened after it, just stuck on the same bootloader screen. The battery died and tab didn't boot again in any way, nor did it showed to be charging.
One of the solutions related to charging it for a while worked to some extent as it finally showed charging screen. But upon booting up, only the LCD turned on with nothing but dark screen (no logo, nothing) - and that too only till the power button was held down. However, the bootloader was accessible. But in bootloader, nothing seemed to work. There are three options in the bootloader:
- System Recovery
- Fastboot mode
- Reboot
I tried entering system recovery but when I selected it, the tab would turn off immediately. I then tried selecting "Reboot", the tab again turned off immediately with no screen/logo or whatsoever. I did not try connecting it to PC at this point.
Could it be that ROM has been damaged? I already found and downloaded its drivers and ROM on PC. The tab hasn't booted since last time nor gets detected by PC, so I'm once again leaving its battery to be depleted for hours and try charging again. I plan to reinstall the ROM on it, if it does gets detected by PC.
My question is,
1. Is there anything else I should try first?
2. Any way to make PC detect it if it doesn't gets detected next time I boot into bootloader/flash mode?
3. Why isn't bootloader working?
Any help would be greatly appreciated!
Here's the list of things that I tried before charging it worked:
1. Hold power button for 1 minute while on charging, as well as without charging.
2. Hold power + volume up (bootloadder combination) for 60 seconds. While on charging + without charging.
3. Connected to computer. Repeated step 2 and 1 along with it.
4. Flash a bright light on its light sensor while holding power button. Also try volume down or up button along with it. As well as on charging + without charging.
5. The charging one was actually tried before, but it only worked when I left it for about 10+ hours without charging and then to charge till the charging screen showed up on its own.
More Information:
The tab was first Factory Reset from the settings, then rooted with the KingRoot 'android app' (not PC). But since there was no SuperSU or related app automatically installed, SuperSU was installed separately. Upon installing SuperSU, a messsage appeared saying something like,"Binary not updated".
The bootloader was accessed to wipe cache partition. It took sometime so it was left alone. It rebooted normally, so assuming it was successful, it was booted into bootloader again.
It was at this point that bootloader got stuck, and I assume that it may have to do with selecting fastboot mode.
Resolved!
It's the third day, and the tab was once again left for its battery to be depleted for around 15 hours and then plugged in to charge for about an hour. It once again finally showed charging screen, but screen would turn on with no logo or anything else (same as before). Thou, before charging screen showed up, tab was removed from charging for a little while this time.
The tab was left to charge for about half an hour before charging screen showed up and then booted again. This time it booted normally and was working fine!
For those who may encounter the same problem, keep trying for at least a week before finally giving up. Here's a few suggestion that some people gave me to try:

3. Play dumb. If it's on warranty, do a warranty claim. They won't be able to tell it's rooted since it doesn't boot up and nothing works.

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
