First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance
Cheers
Request again
Dear mates
I have really very high respect for the forum so please help me out.
ThanQ
Cheers
This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."
Not helping either
Disabled LG modem from Device Manager after installing the USB drivers.
No use
Before going to any service, do a backup and Factory Reset your device, then try again...
I will try this definitely but going to service means 3-4 days without phone . really very scary .
thanks mate
anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

Got exactly the same situation with USB(on different PCs) and also Emergency mode on every reboot(taking battery out for about an hour helps).
Did SD wipe though not sure about factory reset afterwards, gotta try it one more time...

I have tried uninstalling driver and just plugging in with USB but still neither PC nor phone detects USB connection.
I have tried it on Win7, Win Vista and WinXP.
respected mates please help me.
I am on transfer in June so don't want to take chance with Service centre as of Now.

Are you sure you are having the latest driver?
try this:
Code:
csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
install it,
(you may have to choose language from the last tab, 1st or 2nd option)
and choose P500 from "driver installation"
I didnt experience this issue but if i cant help im sorry.

Hi,
I have been trying too Root my S291 for a whole day yesterday. I followed this manual by jozco313:http://forum.xda-developers.com/showthread.php?t=2762565
I tried doing it on two different computers and I had the same problem in both. After I install the drivers on the computer and enabling USB Debugging I open the Root tool and click on the first option, after that my phone shut off (maybe it's still on but with blank screen I'm saying that cause after I click the first button on the Root tool I hear USB disconnect sound and after a second+- I hear the USB connect sound meaning maybe the phone did reboot itself like it supposed to but nothing is happening on the computer or on the phone).
What can I do?
Btw the phone came with a multilanguage Stock ROM B04, today I managed to update the ROM to B11 and tried the root again but I had the exact same problem.
Thanks

Did you run the program as Admin? You might need to disable your anti-virus program momentarily as some of them see these programs as threats and stop them from working correctly and sometimes quarantine the files held within that programs folder. Plus there's no talk of whether or not that method even works on B11 now. But if you go back to that thread on the last current page or 2 they speak of your issue and what was done to resolve. Once again, now that you are on B11, this root method might or might not work anyway.

I have a vzw lg g3 running Android 5.0.1 kernel 3.4.0 software ver vs98524b. I have tried all the one click root systems for the lg devices and nothing will work. Super user installer never runs in download mode and just stays at 0%. Phone also isn't letting me downgrade back to a earlier build using lg flashtool. This is seriously driving me crazy. Can somebody please help me out here.

I remember being able to go back and forth between KK and LP no matter the fail attempts of loosing root, Do you have custom recovery? If you do you can easily boot to it by pressing the power button and the volume down key and enter the recovery from there and flash a rom with root, MAYBE I'M WRONG but that is what I remember doing whenever root was gone. I haven't done this in months so I'm not sure, maybe someone else can help you
Instead of using the one click GUI root...use the script root. It's a sourceforge download I believe..
I believe I have tried this....I'm going to look more. Can someone provide a link? In the meantime ing oibg to try to get back to kk not having any luck
So how I finally got flashed back to kk. Trying to root but seems like my phone isn't cooperating with the scripts. It says waiting for device.....that's all it does. I have ish debugging turned on and drivers installed

It took my device for to finish up the script when it says "waiting for device", not sure if you waited for a while or expected it to be a quick process or not but I am positive that with my device it seemed like it took FOREVER. Just a heads up, not sure if this is much help but just an idea.

Did you have your phone in PTP mode instead of MTP mode? I seem to remember that when I went to root mine I was in MTP mode and it didn't work.
I have tried both pro and mtp
Sent from my VS985 4G using Tapatalk
I also had somewhat of a struggle rooting on 24b. The MTP mode didn't seem to allow Adb access. I think toggling back and forth from mtp to ptp finally allowed adb devices to show the device. Wish I remembered which how to I followed to link you to. Do you have Lg drivers installed?
Here is guide I followed. Thanks to digital-bug for guide that helped me.

I have had similar issues with MTP and ADB access on my V985. What I have discovered fixes mine every time is to plug the mini USB into a USB port on the front of my case or into the add-on card. Essentially not through any hubs and NOT directly hard connected to the motherboard. But a port attached to one of the headers IE front of the case ports. I don't have any good explanations for why this works, but it works. Normally i plug my phone in to a USB 3.0 hub and it, normally, does work, but when it does not I go to the front of the case which is a 2.0 port connected to one of the headers on the board.

I had similar issues ( as well as many others) when trying to root. After many unsuccessful attempts I tried a different computer and it worked like a charm. Both were xp machines. Getting a recovery installed was a different story neither machine worked and after a couple days of frustration I tried the autorec app which did the trick.
Try a different USB cord, also uninstall and reinstall the drivers you might have the wrong driver installed.

Hi guys,
I have been searching for hours but I can't seem to find how to fix my problem.
I have a new Z5 Compact that I was trying to flash with the stock firmware but I somehow managed to brick it. I don't think I had the drivers installed properly when I tried to flash with flashtool but since flashtool didn't even detect my phone or appear to begin flashing it I don't know how I bricked it. Anyway after trying for hours to fix it on my own I can't seem to find the information that I need. I have installed the drivers properly as far as I can tell by allowing unsigned drivers on windows 10 but whenever I boot to flash mode the phone isn't detected. Nothing even comes up in Device Manager so there are no options to update drivers or anything. I just hold the volume down button, plug in the usb, the LED briefly flashes red before holding on green and then nothing happens. Neither Flashtool or PC Companion detect the phone and I have tried this on 2 different laptops running Windows 7 and Windows 10. If anyone has any instructions on how to get this to work on Ubuntu I'm willing to try that too as I also have Ubuntu installed but I am really at a loss for what else I can try.
Any help would be greatly appreciated.
Thank you

sounds dumb but have you tried a different port and different cable? i ran into the same problem and found out one of the ports on my laptop doesnt work for data. flashtool is a major pain, it took me three pcs to find one that it worked with and then it took a good 5 tries and reboots to have a successful flash. flashing twrp and then xpower would be easier imo.

Yeah, I have tried 7 ports and 3 cables across two different pcs. There's a desktop I can try on but I'll wait until tomorrow. It's really frustrating. I just wanted to root so that I could batch install my apps from Titanium but now I have got a brick. In the time that I have spent trying to fix it I could have selected and installed all the apps individually.

keep trying, it'll work after you figure out whats wrong with your install, flashtool is real finnicky. If your already soft bricked and only want root id suggest fastboot twrp 3.0.2 then flash xpower 3.0 and be done with it. the only real reason to use flashtool is to flash a new image onto the phone because you cant take an ota.

I tried following that guide but when I try to install the driver it just says "The INF file you selected does not support this method if installation". You didn't happen to have that problem and find a workaround did you?
Just an update on what I have tried if anyone has any suggestions...
I tried inserting a SIM in case that would make any difference. I have also tried it on a desktop pc as well as the two laptops now which is windows 7, 8.1 and 10. The Windows 8.1 attempt was a clean install and I used the advanced boot method to enable the installation of unsigned drivers. I had high hopes for that but it didn't work. What I find curious is there is no activity when I plug the phone in, in flash mode. If I plug it in, in fastboot mode it searches for drivers and the device appears in device manager but with flash mode I get nothing. I'm beginning to think that perhaps the device itself has a faulty flash mode.

I managed to flash a Z5 Compact with the same model number without any issues on the same computer that won't detect my handset so I'm pretty sure that it's an issue specific to this handset. Thanks everyone for their suggestions.
I got my v30 with a small crack in the screen for cheap from a seller who has a ton of us998's and a handful of ls998's. (Edit, it looks from the seller's feedback that they are indeed frankensteining sprint phones over to unlocked versions to sell for more $$. I'm wondering if they messed something up on this one and that's why it was so cheap.)

I've tried four different cables, one I know worked for rooting my nexus 6p.
I've tried every usb port.
I've tried all of this on a second computer.
I've also tried setting up the phone and doing all this with usb debugging both disabled and enabled.
The main error I get in the device manager is usb "Device Descriptor Request failed" and from the system, "usb device not recognized".
Is there anything else I can do or is this phone toast?
I can get into recovery mode, but it says:
Code:
Unable to open sysfs usb node ( no such file or directory). Trying configfs failed to set driver control: no such device.
Says that twice, then says, not send the package you want to apply to the device with "adb sideload <filenale>". . .
But the computer doesn't recognize it.
Do you think putting the stock kdz on an sd card and updating that way will fix the usb or is this a hardware issue?

You mean by holding the volume up and then plugging the v30 up to a computer?
It just goes to the charging percentage screen. That's it.
Is there any way to update the device via the sd card to the stock firmware and the Recovery mode (vol dn+power) which I can get into? That error above makes me wonder if something is missing. (II Tried putting the stock kdz on an sd card but it didn't see anything there.)

Yeah, with phone turned completely off.
Squeeze the "up" volume button, while simultaneously plugging USB cord into computer.
Shouldn't make any difference but you've turned on USB debugging in Developer Options?

Maybe try Master Reset, which totally resets the device?

Yep.
I've tried the master reset (confirm twice on grey screen),
The update and factory reset inside the system menu,
and the reset by going into the blue recovery screen.
There are some logs too, I just don't know how to get them off the phone.
I suspect that these ls998 can't be Frankensteined to US998 and that's why u got it for cheap. JTAG via Octoplus box (service avail on eBay for $35) is needed to restore download mode

Yeah, these dealers are mass converting using something like Octopus box, and maybe something didn't go right this time...
So, he'll need someone else with Octopus box to fix it, I guess.
Something the sprint store could do? Looks like the seller is willing to swap out, but I'm worried about the quality of the swap. They are all cracked, but hairline vs SHARDS is a big difference.
(I noticed a bunch of the us998 phones listed have ls998u stickers on the back)
I couldn't find listings for people who can restore with octoplus or octopus, what should I search for?
Uploaded two pictures of the recovery menu and what happens when I try to start adb from the phone.
Also, when I run the graphics test, it fails, tries to install something, then fails at that. I took a video of that and the entire log if anyone is curious.

We don't have OTA files for these LS998 do we?
If so, running it should restore download mode. Or if already on the latest OS version, force installing it with LGUP FOTA mode, as described in the post linked below.

The OTA file in there is for H932 (and outdated anyway) but the procedure is the same. You'd need to find an OTA file for your LS998. Not a file created by a Dev, but an OTA Update zip captured by someone on the phone or with LG Bridge. And again, I'm not sure we have those for LS998.

I haven't found one yet, but I was hoping something like that would fix it.
Can u get into bootloader mode? (Powered off, hold vol.down, plug in usb-c while other end plugged into win10 PC usb2 port)
Nope. Just powers up to the charging screen.

Im curious. About the entire log and video you took.
After the latest update of WIndows 10 my V30 wasn't getting recognized. So I installed LG bridge and it asked to update some driver, I clicked yes and after that the phone was detected fine. Maybe try that once

I've reinstalled bridge on both computers. On my desktop it asked me to update my usb driver.
ps I just noticed on the packaging manifest that it says the usb port isn't working, but it's scratched out lol. Mistake on their part.
I'm still guessing it was a bad jtag that screwed up some of the partitions.
Graphics test tries to install stuff and fails
here are the logs, You'll have to slowmo it and pause as necessary. (Didn't include the dmsgs, but I could if anyone wants to see them, it will just take a while.)
