[Q] Bootloops when using OTG - Galaxy S6 Q&A, Help & Troubleshooting

Has anybody else connected via a USB OTG cable to a USB drive? I get stuck in bootloops both when running normally and in recovery mode. I thought this might be a better way to backup my storage since connecting via a USB cable to a computer takes a very long time.
Edit: Working now, seems that the S6 does not like the Stickmount app but supports OTG without an extra app.
Thanks

[Q] USB not recognized

Hi all,
My Droid charge decided to do something weird today; it no longer will USB mount! This problem is particularly bad because, while I can put the phone in download mode, my computer will not recognize the USB and ODIN (1.2 & 1.8) cannot wipe the phone.
Any suggestions? I really need my phone back, but I'm not sure what to do.
Tried reinstalling the USB Samsung Drivers, using the original data cable, and two different computers (Win7). SD card will mount in an external drive (aka without the phone), and the phone will charge via USB. I have the most recent form of CWM on it, and the EP4P debloated and rooted rom.
Thanks,
frak

That happened to me a while back. Mine had the added bonus of going into desk dock mode and staying there. It was a hardware issue with the USB port. It would charge, but nothing else. Mine did become intermittent though, and cycling the cable in and out seemed to help it some, but ultimately, I had to send it in for replacement

What cable are you using? I accidentally grabbed my charging-only cable the other day and didn't realized it only had the wires for positive and negative. No data pins.
Is it the cable that came with your Droid?
Another thread similar. Check it out and try some.

Had that yesterday. A different port worked fine for me. Maybe a couple of power cycles will do the trick.

Usb problem...

Hey all,
I recently got a set up to get my HDD contected to my note. (with y cable for power suply) However when i plug it in it just says usb connecter connected and after a few seconds it tells me that mass storage is savely removed? this happens while the cable is still plugged in and im just waiting without touching any cable etc. Any idea what could cause this problem?

I had read about this somewhere. Cant remember.
I think its an issue with the driver. Just to confirm try another PC.
Or else the usb port or cable is screwed.
Hey thanks for responding . A pc isn't the problem. I'm currently one step further which is that the note 10.1 does see that a usb device is connected but doesn't recognize it as a mass storage device. Any ideas what could solve this?

Ums does not work with stock roms

I'm not using a stock rom though...
I'm not on stock and I had to use a USB OTG app to mount my drive. I used USB OTG Helper but there are others out there that work too.
Will try that but in case it doesn't, what rom are you using?
Thanks again

Same here bro.. using revolution HD.. usb not recognized.. in the device manager detected with unknown device..

I'm not sure if my drive is NTFS or exFAT, that might make a difference. I'm also using a powered USB hub but have been able to mount the drives using the USB OTG helper app that I mentioned. USB seems flaky to me tough... sometimes it works without a hitch, sometimes I have to mess around to get things to connect properly.

I was connecting fine over USB before installing AR and now it reboots the tablet whenever connected to the computer. Strange issue. And a frustrating one because I like to use USB a lot for transferring music and other files.
Installed AR 8.0 because from the description it sounded very "stock" but runs a lot better. It appears it isn't as stock as I had hoped.

thankfully, the issue resolved after flashing darkman's compatibility pack 8.0. you should try rooting...

S6 does not work USB and Wifi. Can not update

Hello, I have a galaxy S6 where after restarting the factory settings stopped working the USB and Wifi. When I try to update the software via OTA I get the message "Your device has been modified. Software updates are not available".
I have already tried to connect it via USB in recovery mode and even then the device is not recognized on any computer. I also tried a new reset with wipe cache and wipe data but it does not resolve. Do you know any alternatives?
Note: The USB port normally charges and if I connect a pen drive via OTG I can copy data.
Install TWRP by USB from PC, and MTP in TWRP should work.

The problem is that USB is not recognized on the PC. The device only appears as charging.

Then you have broken USB port in phone or in cable.
Try another USB cable, if it's not working u have broken it in phone and there is nothing you can do about it expect a repair.

The strange thing is: If I connect a pendrive in the device with the OTG cable I can see and copy files from the pendrive.
