Default [Q] WIndows 8.1 MTP won't stabalize

I have AT&T M8. Windows 8.1. When I connect phone with USB cable the MTP won't establish a secure connection so that phone shows attached to computer and I can explore files. The MTP files show as installed. I have HTC sync manager insatlled. But Media device (MTP) connected flashes non stop and computer keeps asking what to do with phone when connected. File explorer shows phone connected and then gone again in a couple of seconds.
Help please!

Turned out I was using a cheap USB cable. Are you using a good quality cable that can handle data as well as power?

Try a different port. Yes it sounds silly, but I have had this same issue on 3 different types of phones. I would always forget about having this problem and I kept saying what the heck is wrong here until I realized it. I always end up putting it in the wrong port so I ended up labeling the correct port on the PC.
Change is inevitable, except from a vending machine.


Current Phones: Note 3, S4, AT&T S5, TMO S5, & LG G2 . Yes, I'm a phone junkie because I switch between all of my phones and never let them totally die.

Phones sitting on standby in a drawer: iCrap5, iCrap4, Note 1, SGS2, HTC Vivid, Note 2, S3, LG G Pro

My one and only tablet....The awesome Galaxy note 10.1

Thanks for the advice! I have 3 ports on my laptop, I've tried all 3 of them with no luck. I'm trying to s-off using firewater thru adb, after I run the first command "adb reboot" , my phone reboots. I get 3/4 of the way thru the commands for s-off and my computer asks me a bunch of questions about my m8 and then I get disconnected from adb, (no device)? I'm running Windows 8.1, stock root, no mods, screen lock off, usb debug on, fast boot off, sync manager uninstalled from my computer. I'm out of ideas to try. Any help or advice is greatly appreciated.....

If your laptop only has USB3.0 ports, then you'll need to replace the built in Microsoft USB 3.0 drivers with the Intel USB3.0 eXtensible Host Controller drivers. This will give you proper ADB support when your phone reboots into fastboot mode. Also make sure you have proper HTC drivers installed as well (HTC Sync manager drivers should do the job, but if not, the HTC driver links can be found on this site).

Known issue with Windows 8/8.1 USB 3.0 and adb.

Sorry I don't have direct URL's at the moment, but I'm in the middle of a workshift. If you can't find what I'm talking about I'll post more info tomorrow.

Hope this helps.
