[Q] Computers won't detect Phone - Sprint LG Optimus G

Hi, So I've found that computers aren't recognizing my phone. I've made sure its in MTP mode. Drivers and the multiple computers I tried were up to date. The device does charge but no data? My device is softbricked and it's making it difficult to recover because no computer will see the phone. Any help is appreciated.

Cords, cords, cords, and then try another cord. This is, by far, the pickiest phone I've had with chargers. Most of the one I've been using for years give me a slow charging icon on my LGOG. Good luck

I'd guess that your charging port is broken. I had that problem, sent it to LG, and they fixed it for $45 (even though it was under warranty; I was very upset). And now I have this problem again, only a couple weeks later. It doesn't matter which USB cord I use, and I have over a dozen.
I'm beginning to hate this phone.

Not sure what it is, but we only have one of our 5 laptops that can pick up either of our LGOGs.

Something weird I noticed.

So I got my phone on craigslist from a guy. Just the phone, no cables or anything. I tried using my HTC usb cable, but it wouldn't work. I had to buy a legit Samsung cable for it to work. Now that I got rid of the stock ICS and installed a jellybean ROM, the HTC usb cable works now! Which is good, cuz I lost my samsung one.
Any idea why this would happen?
I don't think it matters or will help anyone. Just use OEM cables and one less thing to worry about.

Standard USB cables is universal, they should be all the same, with 4 pins:
Vcc, Data-, Data+, Ground (of course 3.0 have new stuff)
Maybe the HTC cables have built issues or you were using a USB port that wasn't delivering full 5volts. Sometimes I tried flashing Odin and it failed on cheaper USB cables. And since my desktop have weak USB power output, the file transfer to the Nexus fail sometimes unless I use a USB cable with dual connectors connecting to two full USB ports. But I don't think there is any prevention method to make one brand of cable not work with a certain phone brand, this is a universal standard, not Apple. Which is why I refuse to buy Android tablets that use proprietary ports.
Maybe he had something borked in his rom and didn't know and that was why he was unloading it.

Hey its from Craig's list. Anything is possible...

yeah any micro usb cable should pretty much work. everything ive tried works fine (blackberry, samsung, htc, generic ones)
I had the same issue with me g2x charger. Only reason why I wanna use my g2x charger over the Samsung OEM one is because the Samsung one does not fit with my case so I'm forced to take off my case every night so I can charge

He probably had fast charge enabled, which was wiped when you flashed stock JB

Nandroid and warranty.

I am thinking of changing my phone via warranty. Will I still be able to use my nandroid backups on my new glide? USB charging getting worse.

I'd like an update if possible if you are able to get it warrantied? I thought once anything was modified that was it? And won't they argue that the crappy micro-B usb failing is the user's fault, rather than the fact it's an unreliable unresiliant usb port? *I miss the mini-b usb*
If its same carrier then of course same device, I don't see why it would be an issue, just nadroid it before you replace it with an older backup.
I went back to an osimood nandroid backup and guess what my charging is working perfectly! Does this make any sense? Guess my phone does not like ICS. No need to send it in under warranty now.

I'd keep a close watch on it none the less so as to not begin experiencing the problem again only for it to occur outside of the warranty.
#1 Are you using the real Samsung charger? I've stopped using other chargers in an effort to prevent excessive wear/damage to my ports. They fit the most flush and smoothly it seems in comparison to half a dozen other chargers and usb cables I have used.
#2 Are you sure it wasn't just a bad flash? Did a reflash? did a wipe and then flash? Just curious but I'd give that a shot. Also checksum the ICS image you did use to be sure it wasn't a bad download?

Sorry to threadjack, but every Samsung charger/cable I've ever used has barely held itself in the port, loose and floppy like an old hooker's va-jay-jay. (inb4urmomlol)
Now Nokia, those guys can make a damn microusb cable! plug into the charging port, I can pick up my phone and swing it around by the cable if I wanted. takes just a bit of effort to pull the cable off the port...
And now back to your regularly scheduled banter...

Since you mention it, I can't argue. My nokia ports were pretty rock solid, but I still have my old Nokia USB cable, and while so far all of my samsung ports and cables seem pretty solid/not loose, the nokia fits in (short of making any dirty references :laugh pretty snug and too snug for comfort, which is why I mentioned sticking to the original ones in hopes of less force and wear.
I understand loose but now it works with osimood where it didn't before the same exact cables. Seems that there is something that changes with ICS and charging.

Now... That's why I avoid using Samsung's USB cable, they're too much troubles. I have two of them shorting itself out, so the Wacom Bamboo USB cable gets used instead - no problems. I wonder why Samsung makes the most unreliable USB cable, hmm?

USB cables! my wife and I both have Glides and with in 3 to 4 months both of the usb cables broke! I mean the end that plugs into the phone just disintegrated! I use a usb cable that came from a palm one phone, its twice as long and works wonderfully! although be very careful with the port in the phone! was caught in a light rain, and a single drop happen to hit perfectly on the charging port! that ended the usb functionality! still charged but could not use on a pc. I had already rooted the phone! I called att and they sent me a new one on warranty. I got lucky I guess, all I did was delete all the apps the used root and used root explorer to delete superuser.apk. rebooted the phone and sent it in!
I would say if you need to send it in, just flash the leaked ICS update and that will un-root and also restore a stock recovery. there's also a stock 2.3.5 and the stock recovery floating in the forum here somewhere!
Yup... -___- Mine just shorted out, from positive to negative - at least Samsung's charger itself is fault-proof (didn't let out the magic smoke when that occurred).

Ya its strange..I tried each n everything including cleaning ports and changing too!! The most weird part is except my GNEX, all my other devices works fine
I have been dealing with this very same issue for about a month.
So far, without any success, I've tried:
- connecting my gnex to computers running windows 8, windows 7 and Ubuntu. (Removed and reinstalled all drivers using multiple routes.. Gnex toolkit, Samsung drivers, pdanet etc.)
- I've cleaned the USB port multiple times (gentle toothpick, canned air, rubbing alcohol)
- I've disassembled the phone and very carefully removed the USB flex cable to check for damaged ribbon cables.
- reverted to stock ROM
- tried both CWM and TWRP recoveries
I'm now out of ideas. However, there is a replacement USB flex cable on amazon for roughly $7. This is my next and probably final option as I'm no longer on contract with any service provider and use my gnex as a WiFi/sip device.

Is your problem fixed now?
One more weird situation has begun..my gnex charges itself(even though i haven't connected any charger)..it actually doesn't charges but it seems as if i am really charging it! This happens after every few minutes..
No. Still without success. Have not yet ordered the replacement part.
If your biggest issue is transferring files though, there are several apps like Google drive and dropbox that can come in handy as well as file explorers that allow network access over WiFi (I'm about to us ES file explorer to transfer a 2gb file... Hopefully)
From what I've read here on xda and elsewhere, this issue will likely lead to a complete failure of the USB port, meaning no charge either. Best of luck to you that this doesn't happen.
**edit - if you are already rooted, be careful not to undo it, because I've not found a way to root without USB. Also, there is ADB over WiFi, I just haven't messed with it.
Sent from my Galaxy Nexus using xda premium
Exactly ! i am facing the same situation i.e. sometimes my phone charges and sometimes doesn't..even when connecting to computer ,adb doesn't work and it may charge the phone sometimes..
Is my gnex's USB port damaged or is it software related issue?

What does "phantom charge" means?
By phantom charge, I mean that symptom you described of your phone saying it is charging even when it is not plugged in.
I have ruled out software issue for my phone, and likely your phone as well but that is your decision. To me, this is definitely a hardware issue.
The part I linked to is twice as expensive as I remember. Perhaps do some more searching for a better price.

Pc not detecting android but charging

Hi this recently started happening again. Basically plugged my s3 in via usb. Nothing shows in my computer, but phone remains charging. I have tried uninstalling and reinstalling all samsung usb drivers but it does nothing. Tried installing kies/older usb drivers, still no luck. Regardless of if there are drivers or not on my pc, there is no detection what so ever. My pc was detecting my phone perfectly before. Anyone know the solution to this?
try roboot ur phone?
Tryall usb ports on the computer. Is it seen in device manager?
If so try uninstalling from thrre. Then reinstall drivrrs. Uninstall kies and don't reinstall it.

Already tried restarting phone. The samsung drivers are not listed in device manager. I have already uninstalled kies.

Try a different USB cord. I had the same issue with an old USB cord I got off eBay, I would have to adjust the cord a certain way and keep it there for the computer to recognize my phone. I got a new cord and don't have the issue any more.

If you are using a desktop you can try to power it down, unplug the power source, reboot it then try again. If on a laptop, you can try to unplug the power source as well. As strange as it sounds, I was having a similar problem (on windows 7) and this strange fix works every time it happens to me

+1 I have bought a bunch of USB cords online, half of them will only charge but not recognize the device. I would try a different cord first.
I'd say at least try two cables, unless you can confirm one to be good by testing on another device.
Also, try on a different computer. This will at least tell you if the problem is your computer or your phone.

I know, I've lost count of how many cables I've gone threw since my first android device. I found one that was 3 ft. Long and charged my phone quickly, 3 months later it stopped working. I would get one from Samsung but they're too short. Its hard to find the perfect micro USB cord lol.

Yes but as I mentioned before, these cables go bad all the time. Usually wires come loose in the tiny connectors they use. Unless you somehow manage to keep it straight and flat all the time, and never pick k up your phone while it's plugged in, the cable will eventually go bad.

I had the same problem and it turned out to be the cable. It was the one that came with the phone. My phone was bricked because I hadn't checked the md5 of the rom I was flashing so I thought that I had really screwed something up when I couldn't even get the phone to connect to Odin. I was about to file an insurance claim until I finally tried another cable and it worked instantly.

we have the same problem
I tried another USB cord I tried another PC my phone can't detect at any PC but I have all the drivers for my device even the other android phone still can't detect
Where did you get the Samsung drivers? Did you try other USB ports?

[Q]microUSB Port

So I rooted and flashed SlimBean on my T-Mobile G2 a while back and that was all fine and dandy until a few days ago, the microUSB port broke. I am not sure what happened, I didn't change anything except maybe the processor in recent memory. This has happened to many devices that I have seen, but never in this way. Most devices when the port breaks, you have to wiggle the plug until it starts charging. With the G2, I plugged it into my laptop and I got a notification on my laptop that the port I plugged it into was overloaded... Any extra information would be great about this... Recently I changed it to JellyBaby, but the issue still remains. I have tried different cords, computers, and outlets and nothing has given me any response.
Sent from my SGH-T959 using xda app-developers app
oddly enough i had this issue too as soon as i used SlimBean 6.2
now my mac nor either of my pc's read my Desire Z as a USB drive and doesn't prompt me to mount as a disk. I have to use AirDroid to transfer roms now, which is a little inconvenient given the range of my router and distance to my computer.
But it STILL charges fine. I tried with 4 cables too. diferent ports. etc. different roms. different kernels.
I opened a dud Desire Z that i have that broke long time ago to see what is involved in replaceing the USB port but it's not worth me risking to break the phone I currently use and then not being able to charge it at all.
I think I remember one a small plastic object from the microUSB port flaking off. So maybe one of the data pins on the microUSB port came off and it charges but it doesn't detect data connections?
I dunno. I dont feel like it's worth it to check. When a new qwerty phone comes out i'll be happy. Hopefully it lasts long enough for that to happen (if it happens).
if you figure out the issue, let me know! I will test your findings on my phone.
Mine won't charge...

Chances are the port is bad, usually if you peer inside you can see the physical damage but not always
A new port runs about 5$ sometimes less sometimes more but if you search a bit I tend to buy them at about 2$
Replacing one on this phone isn't too bad if your handy with a soldering iron, if you haven't soldered anything before or nothing this small then you may want to have someone do it for you as you can make things worse
External battery chargers are a pain but cheap, but before you invest in anything try a new cable and a new ROM and new firmware (like return to stock or change bootloader etc) if it still won't work near 100% a bad port

Well I am 15 so... No soldering for me.
I have an external battery charger along with two other batteries. That is working so far.
I have tried new:
Cables
Computers
Outlets
ROMs
I cannot try anything below 4.2.2 because I can connect to a computer to do so an do not have any Nandroid backups.
I am also experiencing major cell reception issues, and can't find a post with alternative modems. Do they exist for this phone?

Here you will find links to all things about the vision, don't look for modem the term used is radio.
You can use an external SD adapter to download ROMs from PC or download overnight directly to phone (full batt) or use apps to transfer data between PC and phone, I personally back up my data to dropbox and there tons of others that work great too.
Yeah skip the soldering, but maybe consider either paying someone to do it for you or buying a broken vision on eBay and swapping logic boards, that's easy even for the most novice
Best of luck!
