The phone was running 6.0.1 MM stock when I got it.
It booted normally and worked for a few seconds, everything worked fine and after 10 - 15 seconds it froze and rebooted and it kept on doing that until I removed the battery.
I connected it to the PC but it wasn't detected by odin (the drivers are installed correctly). I got this message from Windows: "Unknown USB Device (Device Descriptor Request Failed)". I tried a few times and everytime this happened.
I kinda gave up but I tried to connect the phone to pc one more time and it got detected by odin like nothing has ever happened.
I flashed Lollipop but it was restarting at the end of the bootanimation.
I bought a new battery.
The "Unknown USB Device (Device Descriptor Request Failed)" problem still exists.
Somehow got detected again so I flashed TWRP and while in recovery the phone "works fine" even with the charger unplugged.
The phone is still useless tho.
Flashed back MM stock and the issue still exists.
I already ordered replacement USB port. It will come soon so i will check if the detection problem is caused by broken USB or software issues.
Also there is a small probability that my "new" battery could be dead too.
hey, bro, i have SM-N915G.
From last few days, i am facing the same issue.
All of a sudden phone keeps rebooting itself until I connect it to the power supply.
after connecting to the charger it gets booted properly.
please help me if you found any solution.

Make sure you had stock recovery on the phone. Other recoveries may make the udpate fail. Try another USB port and reinstall the drivers. The LG and/or the LG Updater program are very picky about USB ports. During the update the LG Update tool resets the USB port after each part of the phone is flashed (i.e., baseband, recovery/boot and system. On mine when it told me to remove the battery I refused and simply removed the USB cable, plugged it back and restarted the update and it worked. This is just the program not seeing the phone reconnecting to the computer and timing out. I heard the phone connect before I got the stupid remove battery message, so I decided to try a simply cable pull and reinsertion first and that did the trick for me (was at 5% in SW update screen on phone). It reset again at 56% and 76% (dropped to 75% after reconnect) but this time the phone reconnected and the software saw it in time to continue the update normally. Good luck.
My friend switched off his phone so he will save battery in his skyrocket, then the phone looked like bricked which is weird. I've tryed to put it in download mode - nothing cwm - nothing, just silence, no vibration, no reaction w/e i've tryed to do. Is there a workaround so I won't have to turn on phone and i could flash rom? AFAIK he had installed CM9 and everything was fine. Weird thing tho. Is there anything that we can do? When i plugin phone to the pc with odin turned on (windows 7) says that the driver is not functioning although i have installed samsung usb drivers and i've connected galaxy note with ease... Then i installed another samsung usb driver somewhere in gs2 skyrocket board. Still no luck. Specifically error says "This device cannot start. (Code 10)"
Well, it just doesn't boot, keys combinations doesn't work anymore and my computer only recognizes the phone if I connect it without the battery plugged ( disassembled ), then the LED turns on green and nothing else happens.
I downgraded to the ICS Version of the device and worked perfectly fine, I used it for about 2 months, but when I noticed the lack of functionality compared to 4.4.1 KitKat I decided to upgrade it via OTA. I downloaded the JB Rom version via OTA to prepare my device again for KitKat, "Install Now", but when the flashing process ended it never turned on again, I almost tried everything without finding a solution. But, when I was trying to do something by my self I noticed something; I can't access to the phone with the battery plugged, but when I remove the battery from the connector and plug it into my PC the LED turns on green and the computer detects that there's a device plugged in without showing any dialog box of which devices is.
If there's any help I would appreciate it. Thanks
What does it say in Device Manager on your PC when you plug in the phone?

It says that I plugged an "Unknown USB Input Device" not detected by RSD but by Windows.
Installing Motorola Drivers didn't solved that problem
Edit: Plugged in without the battery connected to the main board, but the screen it's connected to the device by the two Flex
Hello everyone,
First of all sorry for my English. I'm used to read posts on this site but this is my first post, as I have several issues with my phone. Here are some informations:
Device: SM-G920F
ROM : Stock 6.0.1 September security patch
Rooted
TWRP 3.0.0
Yesterday I began to see USB notifications "USB connected"/"USB disconnected" that appeared very often but my phone was not charging at all. When I wanted to charge it (5% battery left) nothing happened the phone didn't charge, I've tried several chargers.
I rebooted on recovery and tried to mount usb to connect the phone with my PC but impossible, I could'nt click on "mount USB".
And then I did the mistake : I did a total wipe (data, cache, internal storage) thinking to make a new installation...but the phone is not recognized by Odin (I tried several cables, USB ports, Odin versions, drivers installation).
So to sum up now my phone does not charge, has no OS and cannot boot on recovery. It can boot on download mode but not recognized by Odin. And when I plug it to charger or PC there is the battery image with the lightning but nothing moves.
If anyone has an idea of what is happening to my phone, and what to do to repair it would be very nice
Thank you for your help to everyone
Wow, I'm experiencing the same exact problem, how did you solve it?
I rebooted on recovery (twrp) and followed what is explained in a video on youtube called (SOLVED)How to fix can't mount data ,system ,cache
Once my pc recognized my phone I flashed a clean rom with Odin.
Today I still don't know what was the problem
Your phone hade waterdomage, inside usb. You are very luky, if it working now.
I'm experiencing the same exact problem, but in my case there is an error appear (an errors occurs when update) so now there is no power in battery and the the charger are not charging the phone also the pc not recognize the USB , so i don't know what i should do ? :crying:
Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.

I ordered a new USB port board, will let you know the results!
Any results after changing the usb port?
Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help
Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.
