I've just updated my Galaxy Tab 2 7" to OS v4.1.1 (Jelly Bean). Since that I can't connect to my device (from my Windows 8 PC, via USB) anymore.
Most relevant to me is the fact that I can't even debug my Android apps using the tablet (which is actually the reason why I bought it). Eclipse does show it among the adb devices, but in an offline status.
The Android SDK is updated. I've tried to force the install of the drivers via the android_winusb.inf located in the
\android-sdk-windows\extras\google\usb_driver
folder, but it doesn't seem to carry the right pieces of information. Tampering the file by manually adding 'em seems to conflict with the along-coming .cat files.
I've also tried by installing Kies, but even that piece of software can't connect to the device.
What do you suggest? Thanks in advance.
Magically, a new OTA update has come "from above" right to my device just a couple of minutes ago. That fixed the whole thing (no action made on the PC side).
Looking at the "about device" data sheet, Android version is still 4.1.1.
I haven't tracked the previous kernel version nor build number, so I can't see if and how they've changed; but I can write 'em down now, just in the case it may matter for someone else to check against:
Kernel version 3.0.31 - 523998 Build number JRO03C.P3110XXCLK7
