Drivers?

(Sorry if this is a duplicate of some other post, but since the forum search tool seems to have vanished, I don't feel too horrible...)
Last month, I used QPST to install a different PRL. I h ad to download KIES and everything, and it all worked swimmingly. Between then and now, I did an update PRL to see if it would help with a certain problem, so now I am of course on 60683.
I wanted to reload 01115 to see if I could actually get 3G roaming in Milwaukee, but suddenly my phone is no longer recognized by Kies or QSTP. I tried reinstalling the drivers, but it did no good.
I can still access the PHONE and Extenal_SD partitions as drives, I just can't do anything diagnostically.
Any ideas?
Thanks,
Dalmus

Okay, I got it working.
Kies still won't see my phone, but having Kies reinstall the drivers actually got Windows to load the drivers, and I watched what Port the phone was sitting on.
So even though I kept seeing "uknown usb device" in QPST, I selected the proper port anyway, and everything worked.

[Q] Computer/USB Problems

Got a GS3 a little over a month ago in exchange for an Evo LTE that was having serious text message issues. As soon as I got it, I was experiencing absolutely horrible battery life, so I immediately rooted and installed Blazer rom on stock kernel. I did this through Odin, so I had to plug my phone into the computer, which recognized it as a USB storage device so I could access files and whatnot.
Fast forward to now and I"m still having seriously battery life concerns. Today, I ran the one-click unroot/return to 100% stock zip from this link. I tried to plug my phone into my pc to load the file, but though it will charge, the PC won't recognize the phone. I ended up downloading the file to the phone and resetting to stock (thinking I was taking it to Sprint tonight). I made sure the most up-to-date Samsung drivers were installed. I updated my chipset drivers. My USB 3.0 drivers. I even updated the BIOS. Tried three different USB cords and all 14 USB ports (2.0 and 3.0). No luck. Windows keeps saying "One of the USB devices attached to this computer has malfunction and WIndows does not recognize it." I have XP, 7, and 8 all installed on this box and none would properly recognize my phone.
My question is whether this is a computer problem or a phone problem. Given my semi-advanced knowledge of computer hardware, I'm inclined to believe this is actually a problem with the phone, but don't want to go waste an hour or two at Sprint trying to get it fixed. Any insight is greatly appreciated. Picture of actual error included.

Wish I could help. I had a few issues connecting my S3 to my work computer, but downloading the Samsung drivers for the Sprint Galaxy S3 L710 from the Samsung web-site solved that problem. I'm using XP at work. On my home computer and my laptop, which are both using Windows 7 Ultimate, I haven't had an issue though.
Maybe try using the driver from the Samsung web-site or trying to install Samsung Kies and then connecting your phone.

I tried Kies. I installed, uninstalled, and reinstalled the drivers twice, with a restart inbetween each step to be safe. No luck.

Stopped by the Sprint store today. They couldn't get it to work either so as it turns out it was actually the USB port on the phone.

S3 Will not connect to computer.

So last I synced my phone was about a month ago so I went to sync it again yesterday to get all my new music and an error popped up saying "USB Device not recognized" So I went to another computer same thing. One is running win8 the other win7. I uninstalled Kies and all driver and reinstalled them on both computers same thing USB error. I tried my girlfriends S3 today and it connected no problem. So I know its a problem with my phone and not my computers. I have tried clearing the cache rebooting in safe mode and download mode, pulling out the battery and sim and pretty much everything else with no fix. What else am I missing here or what should I try?

No Phone QPST

Hello I have the Samsung Epic Galaxy S2 (SPH-D710) Running JB GB27 and using Agats GB27 as root. I downloaded Samsung drivers from their development site and was able to connect to QPST and CDMA with no problem.
The problem began after I downloaded Kies and installed it. Then I wasn't able to connect to QPST or CDMA anymore indicating 'No Phone' on port when in fact the phone is connected with 'ALL' and 'Modem' set on the phone correctly.
Kies displayed that my samsung drivers were being updated to the latest version. I decided then to delete Kies and unistall the samsung drivers Kies updated for me. Cleared out the registry and orphaned files left over reboot. Re-installed my previous samsung drivers but to no avail.
I'd appreciate any and all feedback
Thank You

[Q]MTP

I've recently arrived home from vacation and I've installed the latest LG mobile driver direct from the LG website (vers. 3.11). Trouble is, Windows doesn't say anything about drivers uninstalled properly or anything, drivers are properly installed but it can't go into MTP mode.
anyone have some suggestions?

Which rom are you using? I have the same problem with gee based roms. Stock and gproj roms are working fine.

I think this is stock 4.1.2? This is a converted F180K though so I'm pretty sure this is some knockoff.
Anyway since I'm not so sure, here's a screenshot I took.

Nevermind. Found workaround. Installed WiFi File Transfer to act as replacement for MTP, will also use superbeam to beam large files from pc to phone (phone to pc does not work though, wonder why).
