Possible solution for USB error (device unknown in Windows) - Galaxy S I9000 General

Hi all!
On my I9000 4-5 months ago the USB connection to PC went dead (unknown device error in Windows), but the phone was functioning normally. 3 weeks ago the phone frozed completely, and don't even started, was stucked at boot logo. I managed to enter download mode, but since the USB was not recognised, I could not reflash with a new rom. I tried several PC-s, several cables, many many times, with the seame error (unknown device). I sent the phone to the service, even they said that the main panel need to be changed.
Today I had an idea (brilliant!!) to heat the phone with a hairdryer. When it was hot, plugged on the USB cable, and a miracle happened! The laptop recognised instantly the Samsung Android device, and I managed to reflash with odin, and now the phone is working well, even USB is working now!!!
I dont know, maybe this will help anyone who has the same problem. It is worth a try!

Seriously????

Well I just hope this is not a joke. Am having th same problem. Am gonna try your solution out.
Thanks

And the hairdryer fried the lint in USB connector?
Using tooth brush could be a safer route to go.

Wizard won't start

Dear users,
My Wizard won't start.
Information:
- Stuck at bootloader
- Hard reset won't work
- Updating (at windows xp) won't work, as it stops at 99% (tried 3 roms, even the original from t-mobile). Giving a communication error and my wizard keeps rebooting.
When did this start? After using Button_rom 1.5, it stopped at 99% =)
Anyone that can help me?
Thank you

Mostly,Communication errors are due to weak or drained battery,get it fully charged.
Secondly,get the phone in Bootloaders (RGB) screen and hook it up with pc via usb cable and watch small usb appear at the bottom of the Bootloader,if its there,then reflash the official rom,if its not there,then its a connectivity problem.Either the usb cable is faulty or the mini usb port of the phone.You can even try by changing and plugging the usb cable in another pc usb port.
BTW, remove any sdcard or minisd inserted in the phone before flashing.

Thank you,
My phone had problems recently. It won't start without power cable. And it suddenly shutdowns as I am playing games or listening to music.
It allways hangs at 99%, and with the original ROM it hangs at 80% and also gives the error. It just reboots =(
Ive powered the phone up the all night, after that I tried to flash a rom, but it gave me the exact error at 99%.

[Q] USB Port Charges but no sync/detection by PC.

hi guys, just to say that i read and have been reading for almost 2 weeks now on everything i could find and seems no one has been able to fix.
Some threads go on for 4 pages and then it turns out to be the cable etc which i found fustrating as surely should of have checked cable first before posting.
Anyhow, my usb stopped working randomly, it charges fine but doesnt connect to computer what so ever, as if i never plug it in. If i do plug in a OTG cable to the phone it says usb connected and then disappears.
What i've done so far after countless hours of reading.
- Replaced USB connector with new part
- Reflashed a stock rom with mobile Odin pro
- Flashed PURE Google Rom 4.3 pre rooted with TWRP,
- installed CWM Phillz touch revocovery over TWRP
- Tried phone on 3 different computers all with kies and drivers installed, no luck.
- Tried many different cables
- Tried other samsung phones with those cables on all pc's work fine.
- Updated kernel via odin
- Tried to boot without micro SD card inserted etc.
Is there anything else that i missed? Anything else you could suggest? maybe i put the wrong rom on? possibly a PIT error?
bear in mind phones warranty is VOID untill i can get the USB working again. or even maybe because i replaced the usb connector my self if they can tell i opened the phone then also void.

Thanks for the reply and sorry for the super late reply as I was doing donkey hours at work due to colleagues not turning up.
Eitherway, I tried that solution for me and that was also a no go. Mount unsuccessful for the error iirc.
Would it help to say that i used to connect my external hdd to the phone previously and used to do so with a OTG cable and when the phone didn't read my hdds because they were ntfs i used a program called stickmount pro and others, possibly could it be that those programs caused an error?
Also i have come to realize that my memory card has now been corrupted and I can't read some of the data on it while in the phone or while using an external card reader.
Could this possibly be anything to do with the PIT? As that's the only thing I think I havnt been able to do?

[Q] Windows will not recognize Note 3 anymore, help please!

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks
Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?
Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.
Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Thank you! Worked perfectly!
I have the same problem, do you have any solutions ? Thanks.
I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!
please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...
I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!

[Q] LG G2 USB Not Recognized

Hi, background is this..
I have a D802-10C G2 that i rooted the stock 4.2.2 rom a while back using the post chinese method. Easy enough, all worked fine. no complaints. A couple of weeks ago i got offered the OTA 4.4 update, this failed due to the root. I then removed the root using the feature in super su. that seems to have worked as no apps or file managers etc could get root access. However, the OTA still wont work.
Now my problem is my phone will no longer be recognized by any operating system, on multiple computers. I have tried many ADB drivers, Windows 7 wont even detect the device, i've used every PC connect mode, USB debugging. However always the same result, it's as if i'm plugging in a blank usb cable into the computer. Nothing at all.
The only thing that does happen when i connect the phone to a computer is the phone starts to trickle charge. There is nothing detected in Device Manager in Windows 7 I've tried connecting in download mode, nothing. I've tried the LG support tool, PC sync. Nothing.
WiFi does connect to the PC suite fine BTW and other than that the phone is working perfectly. I've also tried connecting multiple usb cables on multiple ports.
I haven't been able to find a single case of the same problem in the week or so i've been looking. Hoping someone can help, i'm thinking i may have soft bricked my phone. I really do not think this is a driver issue.
Any help would be great. cheers

YOu can try checking the device manager or use other USB port on your phone.

The problem is not like the usual ones you will see about "computer not being able to see device" I don't think it's a driver or software issue, or if it is it's unlike any i have found in the weeks i've been searching the net for a solution. Here's why....
When i connect the phone to Windows 7 and 8 ( on 3 different computers) No hardware is detected, nothing in the Device Manager, no yellow question marks indicating 'Unknown Hardware'. Nothing, all it does is start trickle charging.
Now even with no ADB, or any driver at all installed, the computer should still detect the phone. Mine does not.
The same thing happens using OSX and Linux Mint 16 (again multiple computers) No devices or mounted or volumes shown at all. Linux terminal command "$ lsusb" does not list my hardware.
This is why i'm pretty much convinced that there is something wrong with the USB port on the phone. Because, if Linux can't see it then surely it's a hardware problem right?
The only other thing i can think of is, i have messed up the phones firmware while trying to unroot it? but only because the timing of all this is just too uncanny.
I think i'll have to suck it up and admit defeat here. Funny thing is the phone works perfectly and charges fine.
Stuck on 4.2 , with no ADB functionality. Perhaps i'll sell it cheap to someone who doesn't care.
Cheers for the reply mate.
Same problem here!
Only my G2 is not rooted, it is still on factory OS and recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB ison on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definetly there seems to be a problem with the phone, but I don't beleive it's a software but a firmware problem.
Please help if anyone knows what to do.
same thing happened after installing T-mobile rom thrugh twrp. but my device boots into fastboot and i tryed falshing :
laf.img, boot.img, aboot.img, recovery.img, laf.img
but after reboot my LS980 dissapear from device manager and stucked on LG logo.
Dont know what to do now.
I'm no expert, but given there are a lot of them here and none have weighed in on this with any ideas for a fix, i'm going to assume it's a hardware problem.
Anyone else agree? Hardware problem not software?
Cheers
I guess that you already wiped everything right? Apart from that, i'll suggest you to go to some tech supp and ask them if they can verify that each pin of the micro usb is properly working.
Sorry for my english, hope it helps!

I will try to check the connector although i dont think that it is a hardware issue.
BTW I can enter the download mode after flashing the mentioned partitions and i can also enter the stock LG recovery but when i do the factory reset it keeps showing Factory reset processing ... for ever
It has happened to me the same thing :crying:, and is a problem with the boot.img, if by chance your G2 version 4.4.2 and the the 4.2.2 boot.img, goodbye.
The only solution is to take it to repair a service official, there will change you the card, with the consequent change of IMEI.quent change of IMEI.

I have some kinds of that problem, let try:
Settings -> General -> PC Connection -> Select USB connection method -> Media device (MTP) (or whatever)
Got this same issue after flashing cloudy g3 rom. Then later flashing dirty unicorns, which requires jelly bean baseband. But even restoring g3 and 24a baseband, still doesn't work. No pc tethering and no on the go usb. My usb port is basically charge only.

Everything else works fine...I actually never even noticed this bc I never tether to pc. But now I have to bc I want flask kdz

Also found a description of the same problem here: https://www.reddit.com/r/lgg2/comments/2urpnw/lg_g2_usb_only_charging_not_recognized_by_pc/ - no solutions, too.

What happens when you put the old board back?
Honestly I haven't put the old board back in because it's such a pain to swap out.
I've had this exact same problem - installed a new daughterboard (trying to fix the muffled microphone issue) and the phone could not fast-charge or perform data transfer. Reinstalled the old daughterboard, and charging and data transfer worked again. Not sure what I'm missing.
