Phone not seen by computer - T-Mobile, Samsung Galaxy SIII

After I flashed one of the recent deodexed leak roms my pc would no longer see my phone. The phone would charge but no notification in the phone and no com port was assigned to phone. I tried everything I could find in these threads; restart the computer, use quality usb cord, wipe cache partition, wipe dalvik cache, re-install drivers, and factory reset. I even superwiped and re flashed. What did the trick was just going into download mode. The computer immediatly saw the phone and installed drivers. After the drivers were installed I restarted the phone and everything was good.
Thought I would share.

Cant connect S3 to pc via USB connection?

For some odd reason when I plug my phone into my computer it does not show up. I have a mac so I have to change it to camera only connection. It always used to have a option appears in the notification center for media device and then digital camera. Now it doesn't appear. I also tried connecting it to a windows pc and nothing. So im wondering if this is a wicked v3 rom issue or what.
I tried wiping cache and dalvik cache. NOTHING
Tried rebooting both the pc and phone. NOTHING
Tried a diffrent pc. NOTHING
Help!?!?!

Phone not recognized via USB

Having problems with SIM not being read on 4.2.2 CM rom (I bought the phone with said ROM installed). Decided to try to dowgrade to 4.1.1 official Stock rom. Problem is my phone will not be recognized with any USB cables. I have tried 3 cables and will try more (though I know these cables work fine) and will try a different PC tomorrow,.. but this PC is not the problem, I can tell you that.
I have tried installing the drivers provided in the toolkit and the phone is still not recognized. Have also tried installing Kies, and device is still not recognized. Have tried rebooting phone and PC and still not recoginizing. ADB in developer options is enabled.
When I say not recognized, I don't mean that Windows is popping up saying "device not recognized" - my PC is not even finding the device. There is nothing in Devices and Printers, nothing in Device Manager, nothing in My Computer... I also tried doing factory reset / cache wipe / dalvik cache wipe. Still nothing. Is there any way to flash back to stock rom using CWM restore menu via a ZIP? I can drop the file on a microSD card and restore it from there, but I don't know if there is any way to do that from CWM.

[Q] Bricked Gio - No Boot, No Recovery, Only Download Mode, Odin Doesn't Detect

Hey there guys!
Recently I wanted to get some custom ROM on my brother's Gio. It had stock Samsung software on it, did a factory wipe in recovery, worked perfectly, then I installed CWM in the orignal recovery from the SD card - didn't root before. Since then I can't boot into Recovery, however Android booted up. I tried to use some apps in software to get rid of this problem, but ROM Manager said the device is not supported, then I tried another one called Rashr, which had a question relating to recovery I guess instantly on the app's startup, I hit "Reboot" since then the phone is bricked. If I turn it on with just the power button, it shows the Samsung logo, stuck in a bootloop. I can't access recovery, only dumpram, and Download Modes. I tried fixing this with reinstalling the stock stuff through Odin, but the software doesn't detect the phone. Tried installing Kies, standalone USB drivers, multiple Odin versions, different cables, ports, different computer, nothing worked. When I connect the phone to my PC it plays the "device connected sound" but I got a message, that it's an unidentified device. Went into Device manager, where it recognizes it as a Samsung USB device, with the yellow triangle. Tried updating the driver manually from the manufacturer's list, uninstalling then reinstalling the drivers with no luck. Also I tried cleaning the USB port of the phone, still nothing.
The computers I've tried are running Windows 8.1.
Please help me, I think I've tried everything still the device is bricked.
I have same problem.
did you fix it ?
weLL ,sad to say it but ,its neither worth the effort,time or my typing these letters up here to remind you ,that it's neither the end of days or expensive to buy something this side of the stone aGe ! have fun but not with that one ;(
