Good evening,
I bought a second-hand LG G2 32go, and I realized that it had been rotted by the previous owner (while I had asked him if the telephone was "blank" of any root).
In brief, the telephone is never detected on any PC (tried on different 2, with various drivers) by USB (I just manage to see it in WiFi).
In normal mode (phone started), with the good parameters (Synchronization Media and Debugging USB): no LG tools detect it. I tried with several cables, several PC, several drivers.
I have access to the download mode (it is here I realized that it was rooted): still not detected by Flash Tool.
Hard Reset tried unsuccessfully.
The Android version of the phone is 4.4.2 stock, Pit version 3.4.0, Build KOT49l. D80220b and software version D80220b-EUR-XX.
I'm appealing to you because in my researches, I found cases of defective USB cables, bad configuration, or still " I found, that works !" but which do not share the solution
I had a S3 before, with whom I spent hours of research, but with G2, I am too fast submerged by links and too numerous solutions and I do not find myself there any more.
Then would you have an idea or a solution to help me ? I just want that phone to be detected by USB.
Thank you very much beforehand
Try to clean the usb port

Any other idea please ?

Hey guys, need the help of some XDA geniuses here. I'm usually on the android side of the site but got an issue with this
I received the phone from a friend of mine, brand new, never used before and really wanted to try Windows phone 7. Upon turning it on, the phone just stuck at Samsung boot screen and hung there. I turned to Google, it appears to be a common problem fixable with WP7 loader.
Unfortunately, for some reason, when trying WP7 downloaded (tried 7.05, 7.21, and 7.41)it comes up with the same issue. Write fail on MIBIB and on two occasions when it gets passed that, it freezes on PDA write.
Few pieces of info
Rev 1.3
Able to get to download screen
Downloaded the supersport auto flash samsung-i917-focus-firmware-UCJK2-ATT-USA
Also Samsung focus USB driver
I'm really hoping its not a hardware issue cause I was hoping to use this for a while so if any of you can help out, that would be amazing.
Thanks
On how many comps have you tried?
Possible things to consider/try:
- different computers
- different usb ports
- different usb cable (try a samsung cable not a generic one)
- the attached WP7 downloaders (try 7.41 first and then 7.03 - this one I have from my I8700 but should work)

I have tried this on two different machines and different USB ports on each computer. Also unfortunately, I could not locate the stock USB cable that came with but I did use my HTC evo 3D micro USB cable which I used to flash multiple android Roms. Can't imagine the cables would be terribly different but I'll try a blackberry micro usb . I will try the particular wp7 loaders you Gave me, thanks and I'll check the links for any more info that I may have overlooked previously.
Alright, well, it finished the flash this time, but the phone still stuck on boot. I now tried this on three computers so I've got nothing.
Also I checked over all the other links and there isn't anything new there. Anything else I can try?
OK, so another symptom is, after flashing MAGLDR, even multiple times, I still can't get to it. Volume down, camera and power just has the phone rebooting over and over, download ,mode is available though.
Anything else to try?
Having the same problem
Hi guys so i'm having the same problem as described above, is there a fix for this as yet? anyone with a fix please feel free to contact me at [email protected] :good:
i have problem in my phone samsung OMNIA7 i was flash him but he did not work i mean he still write samsung OMNIA 7 start and off i don't know what is the problem please help me thanks
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!
Sent from my LG-D802 using XDA Free mobile app
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.

Sirs, I flashed the baseband (https://www.androidfilehost.com/?w=files&flid=12880) then it got working back.

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.
---------- Post added at 03:58 PM ---------- Previous post was at 03:56 PM ----------
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

I also have the same problem.
It happened when I tried to backup info through LG PC Suite: the phone disconnected during the process, and now it's not recognized by any PC (http://forum.xda-developers.com/lg-g2/help/lg-g2-recognized-windows-backup-t3155323).
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.
Did anyone manage to fix this?

I really hope you found a solution. Ive been looking an answer for this annoying problem for 6 months!
Ive read almost 50 threads in differents forums about this problem but no solution at all.
- Tried changing charging port. Cost me a few dollars but no solution.
- Tried USB debugging on and off from developers menu.
- Did MTP+ADB option in *#*#0808#* menu.
- Turned Low Battery Dump "on" in *#*#0808#* menu.
- Tried 10 or more different original Samsung cables.
- Upgraded PC USB drivers.
None of them worked for me.
Hope you have made a progress.
Hello guys,
after trying everything I could imagine and find on the net, I still didn't get my PC to recognize my S6 edge plus.
Hopefully someone od you has got some more ideas.
The Problem:
Connected Phone shows "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. No MTP connection and no ADB possible so far.
Done so far:
Samsung USB Mobile Drivers
Kies
Smart Switch (with reinstall of drivers)
6 different cables with 4 PCs (2 Win10, 1 Win7, 1 Linux)
USB-Debugging on / off
*#0808# switched through every mode
USB-Hub drivers
Factory Reset
More Info:
5 of the 6 cables are working just fine for data connection with my S3
There is no infobar tooltip to change USB mode at all, just telling me it's loading
In Download Mode the phone doesn't get recognized by Odin (with same cord and USB Port the S3 does)
In Stock Recovery Sideload Mode the Device does not show up in adb devices (with same cord and USB Port the S3 does)
Regards
up
I'm guessing you have downloaded and installed the Samsung drivers?
New Infos on this case:
Local tech support inspected the phone. They suspect the mainboard to be defective due to corrosion signs.
Of course the repair cost would be ridiculous.
I'm gonna repair it myself, but I'm not quite sure if it's really a faulty mainboard.
I rather think of changing the USB board first, because it's like a 10th of the mainboard and more likely to get wet if that's the reason for the damaged phone.
Any ideas??
Regards
You didn't mention if it charges via USB?
Im in the same situation..
charge via usb but is not able to recognize the phone in any computer (a lot of different cables with 3 PCs)
My unit was wet and i think that something is wrong for this reason.

Hi Cento50. Have You managed to get the phone to work? At first my phone was showing up in "This PC" on Win 10. but after trying Samsung usb drivers to get Odin3 working now it is the same as Yours. Shows in Device Manager as: Unknown USB Device (Device Descriptor Request Failed). A strange Conundrum.
Hello @Photobil2012 yes fix habe worked!
One little wire have replaced 2ohm resistor.
And have fix fast charger and data comunication with PC!
We i have repaced first one diode.
Phone a this time work complete.
First this problem i have connected one hard disk to otg cable with phone battery low!
My suggestion Please caution to use otg interface with high current if have low battery in the phone.
This cause high current drain and possibile burn diode and resistor.
Hi Cento50,
Alright! Thank you very much for the most timely reply and tech info on the successful fix. This is very good news to receive. I just replaced the battery so it is brand new and that works fine now. However, if it is necessary I can apply the same type of fix that you applied. Great work, and thanks again for your help.
Hello everyone,
I own the samsung galaxy note 10.1 edition 2014 and for some years now I have not been able to use it properly. When I put the tablet to charge, I have a red cross on the battery. Following much research, no proposals have allowed to fix the problem. I notably changed the battery, the charging port as well as the cable and the charger (while all the original components seem to work).
On one of the forums, I read that changing the rom and updating it on lineage on android 7 could have solved the problem. It also suited me because many applications that I use every day no longer work on the tablet.
So I try to root the tablet but once again a problem arises, odin cannot find the tablet in download mode. So I look at the device manager and I see that indeed on the usb port there is registered device descriptor request failed. So I go back to the forums, I try again a multitude of soultions that do not work as installed, uninstalled, reinstalled the drivers. Make manipulations in windows. Change USB port, cable. Activate debug mode or not. I even put the old charging port back. Nothing to do I always have the same message.
I also thought to myself that it was because I can't choose MTP mode on the tablet, I tried to do some research, I couldn't find anything conclusive.
So I'm in dire straits, I'm waiting for my savior :crying:
Thank's in advance for answers
Sincerelly
Ps: My tablet is in kitkat version and I cannot switch it to the lolipop version because I have a message telling me that the tablet has been modified.
