Phone not detecting my USB connection - AT&T LG Optimus G

Hello all, I'm having issues with my lg optimus g that I purchased from a friend recently.
The phone itself is in great condition, no signs of wear and tear and he's had it since launch.
He explained to me when I bought it that none of the things he'd tried would allow the phone to make a working connection to a computer. This is all across the board, in no mode can I get a connection. Bootloader, recovery, or normal boot. Now what's even weirder is that the phone doesn't even seem to know that its been connected to a computer either. None of the standard USB debugging or select connection type prompts appear.
It is not such a huge deal to me but I would like to know what is causing it and if it can be fixed..
Thanks for any insight or information you can give me.

Wont sync or be recognized by USB

im having a problem in which my touch pro will not sync or be recognized by ANY type of usb connection (ie, advanced network functionallity unchecked, disk drive mode) it syncs via bluetooth just fine, and when connected to the computer via usb the dialog box asking which type of connection still pops up and it still charges, but no type of connection will go through, i have tried everything except for a hard reset which is what im really avoiding because i have it finally running exactly how i wanted (complete with manila 2.1 on wm6.1 htc 2.01 rom which took me an hour to get working exactly how i wanted), any suggestions, im going crazy here

from where i sit, it sounds like u've spent more time fussing with the no-usb problem more than the hour it'd take to "setup" your phone lol.
can you provide any more info? when did it start happening? have you tried from a couple different computers? cables? please give as much information as you have on the entire subject so we dont have to "drag it out of you" as you are the one requesting assistance dont make us do all the work
I have been having same issue with my Touch Pro. It was working great a few weeks ago...then it just stopped...my pc can't sync or recognized the device. I have been doing extensive reading on so many posts...but nothing seems to work. I finally gave up and a did a hard reset last week...guess what? It still did not work. I suspect it might be a hardware failure. Here is what i did and it was unsuccessful:
Install and then uninstall WMD...nothing, bought new OEM data cables (2 to a pack)...nothing, unchecked the advance network functionaility...nothing, someone recommend to swipe the connection inside the phone for possible dust...nothing, tried on my laptop, desktop PC, work PC and my UMPC (all worked before)...nothing, i tried different usb ports on ALL pcs...nothing, started up ICS and connect (supposedly it will install drivers needed)...nothing.
I also notice that some of the chargers I had for it-also stopped working. Only OEM chargers work now.
Also, there are MANY people complaining about this problem as well...
so I use this program, WIFI Remote Access v1 beta 4, freeware to add apps or make changes via wifi. Works great.

Wish I could find a "fix" for this issue...I can't sent it to Sprint or have a warranty since I flashed it over to Metro PCS...like I said it was working for the past 5 months or so...

well probably last weekend it started happening in which WMDC would just drop the connection and wouldnt reconnect until i rebooted the PC and yesterday morning it also wouldnt connect till i rebooted the pc then it synced and added songs just fine, then i went to school and sat down on one of the computers there and worked on a paper i had to do, this was the last time it worked at all, i got back home and when i connected it to the PC no connections accepted at all, ive rebotted and soft resetted about several times to no avail.
**UPDATE**
i just bit the bullet and did a hard reset and guess what?...........still not working so im resyncing everything through bluetooth and soon will reinstall manilla2.1, after this i will be going to sprint tech support, maybe i can have it exchanged for a TP2
well so yesterday i went up to the sprint store, explained my situation to them and said that ive even done hard resets, they guy had me turn in my phone to him and said that the repair would only take 45mins well 70 passed before i saw my phone again and when i got it back they told me that the reason it wouldnt sync is due to all the 3rd party programs i had installed (only 3rd party program was spb pocket plus) all other installed programs were made by microsoft,sprint and htc. so they did a hard reset and told me it synced their computer fine and that it may be a problem with my computer so got home and it STILL DID NOT WORK!! i even plugged in my axim x51v and it synced without problems,i cant believe i wasted 5 hours of my time and pay an extra $7 for such unprofessional service. they didnt even offer me a new USB cable.
Hey eric,
I have been to other sites and there other members experiencing the same thing. This is the first time hearing it was a 3rd party app...you know it isn't an app if you do a hard reset, which I DID...and it still my pc doesn't recognize it. In my case, it was working great one day...and the next day- it just stopped working.
Now my wif also went haywire. And a hard reset didn't fix that either...
I will be getting the Touch Pro2 soon. I never experience any issues when I had the HTC Mogul...my HTC Pro...well I love it...but i can't deal with the hardware issues...I just replaced my keyboard not to long ago.
Sorry to hear Sprint gave you the run around...
edit: I read somewhere in another post...that sometimes the wifi wire can get unplugged after installing a new keyboard...I opened it up and found the wifi wire (on the back side) plugged in the wrong connector. I must have unplugged it accidentally and then plugged in on the wrong connector. Found the error...now wifi works great.
I've began to have the same issues as well. Last week I flashed vet's ROM and thats when it died. I tried hard resets and other ROMS and its still the same thing so I dont believe it was vet's ROM but more of a hardware issue.
I have no activesync functionality, no flash ability over USB, but charging and disk drive work fine.

I never had this issue. Only internet stops working with the weather updates and skyfire, Im on metro, I just reflash the cab for the internet and that fixes that. But did anyone else try flashing a new rom like hemirunner426 did? Could be worth a shot to get it working. Sounds like urs is F'ed dood sorry.
well I bought a new usb cable from ebay for only $3.xx and since it arrived my usb functionality was restored.
Its usually a problem with the usb cord. I had this same problem before. Just go to the sprint store and they will exchange the cord for free, they also redesigned the cord do it doesnt keep breaking.

I'm suddenly having this problem now.....I have switched to 2 different computers (freshly formatted), flashed to 2 other ROMs via SD card but still no luck with the sync through WMDC.....It charges the phone but will not sync. Any ideas from the gurus??

[Q] Sprint Touch Pro 2 bricked or not?!

Hey guys this is my first post in the forums, and an unfortunate one at that !!
First of all I'd like to say thanks to anyone who can help a sister out , and thanks to all the people who contribute to XDA and it's awesome community.
Here is the issue, I was trying to switch the TP2 from Sprint to T-mobile services, followed directions as said and now the phone will not turn on at all.
However the phone is still being detected in device manager as an unknown device and it says Qualcomm CDMA technologies msm. I have tried installing the driver, with no results.
It will not go into boot loader, and it will not hard reset, I've tried every combination of pushing buttons I can think of, even the small little reset button.
Is this phone bricked?
Or is there a miracle that I can get it to work properly again?
EDIT: The strangest thing is that if the battery, sim, and sdcard are out the phone led will blink for a split second when connected usb to pc or a charger.

Can't conect O1 via USB to PC

Hello.
I use BlackBird 2.3.4 ROM. Before two days(i believe its not cuz of the ROM,i have it from like week) the USB stopped working. When i conect the cable it shows USB icon in statusbar,and its says USB Conected-click to copy files from/to pc. But when i click nothing happens-the USB dialog opens for like a sec and exit by itself. I've tried with disabling USB debugging,but it didnt help. "Mass storage only" option not working too.
I had faced a similar problem. The thing is bloody LG makes pathetic hardware. It is definitely hardware fault.
Maybe you can try to flash another ROM or kernel and see if it works out... Maybe try to connect it to some other PC... if nothing works, then LG service center is the only option.
Mine started working again automatically after a few days. But the data transfer rate has become so slow that I hate it. Cannot go to the service center because I am on CyanogenMod 7.
I am going to shift to a better phone in a few months. Maybe Galaxy Nexus in 8 to 10 months if it comes down to around $500 unlocked...
Never again LG...
Gauhar is right, LG is a pathetic phone maker. Try to flash your O1 back to V20C (LG 2.3.3 Gingerbread for Optimus One). LG's service centres will either charge you a premium, or refuse from repairing the phone, cause they can deal only with LG's ROMs.
Like GauharJK, wait for a few days or try other PCs. Even if that is useless, throw your phone into a gutter and get something better like Samsung or Sony Ericsson.
Yup ,LG sucks hardware wise ...
And I too faced same problem :: Phone not at all Connecting to PC , tried everything .
The culprit for You me and Everyone is PCB of this phone..
Which these LG Service guys take weeks to replace !

Android auto issue

I have a 2016 honda civic ex, and their an issue with AA, the phone goes into a loop of disconnecting/connecting until it either said phone cannot connect or it launches AA now with phone doesnt connect the phone begin to charge normally and since my phone is in debugging mode i am able to swap usb connection type, so i got from file mode, to usb drive back to file mode and it connects (only tried once) now i am posting here to see if anyone has tip for issue with AA or if their a way to get some log for u guys to look into when phone try to do AA
What Android Auto unit do you have? I have been using my honor 5X with my Hyundai Sonata and have no issues with Android Auto.
I have a Pioneer avh4100nex and haven't had an issue with it. I am unlocked and rooted too. In the past on my G4 it would hiccup from time to time and I could clear the AA app out from memory *killing process* and then reconnect and it would work like a champ. What head unit are you using?
I know this is an old thread but I am having the same issues with my 2017 Honda Accord. Did anyone have any luck with CM13? I am getting a this phone is not compatible error message thank you all in advance.
Should also mention it is on 6.0.1 and have tried multiple USB cords. Have not rooted it yet.

LG G3 WiFi Troubleshooting

Hey Guys
I have some questions related to my 3 year old LG G3 (32gig Version), which acts funny within the last few weeks...
First of all, my phone is not rooted (I use Android 5) and I have installed a new battery like 3 months ago.
So now to the problems:
My Phone will only very rarely connect to any WiFi I normally use. Even if I try to manually connect and/or forget the network and reenter the codeword, it won't connect 9 from 10 times. It says connecting.... and then saved.
So normally, I then turn of and on WiFi on the Phone, reboot the router, reboot the phone and eventually it's going to work, but it may take 10 to 15 times.... Does anyone know, what might be the problem?
Next, if I reboot my phone, sometimes it will not recognize my Sim-Card, even though it's always inserted. Here too, I reboot my phone several times, untill it recognizes the card again. But if it does, it always changes my phone language from English to German (well, thats not a big issue for me, just wanted to list it aswell...)
And the last problem, which is also wlan related: For 2 weeks now, I'm no longer able to find the phone-hotspot on my Laptop. It worked without problem before, but now, I can't even find it in the Networks list from my Laptop.... I fear, that this might be related to my phone not connecting to WiFi Networks, alltough this works at least some times and my phone sees all the networks....
So what you think? Is there still hope for my phone or do I have to get a new one? Would be a shame, cause I really like it otherwise...
Thanks a lot for your help
Greets Clara
same problem here.
Were you able to find a fix? Its a hardware issue, I think
