Can anyone help me on this, it's driving me mad as I've tried everything for quite a long time.
I have an S3 which could connect fine of my Win7x64 laptop and then I got an S4. I cleared my S3 and reflashed a clean ROM. Now my S4 can connect via USB and I can use both its storage but S3 won't be recognized. I hear the first beep upon connection and then a triple-fail sound. In system manager I see the attached icon.
If I mount from recovery I can see only the SD card but internal is seen an inaccessible drive (maybe that's how it should be as one card is mounted anyway). Later when I enter my ROM it still won't recognize. I've tried to install KIES although I never had it, it didn't help so I uninstalled it. Then I uninstalled all existing drivers and install latest Smasung drivers from here. Still no luck. The drivers must be ok on my PC since my S4 connects correctly but S3 won't.
All other users of the same ROM (Omega) report that USB connection works flawlessly so it can't be the ROM. Any help on this?
