[Q] help laptop wont recognize download mode

ok i recently accidently flashed a stock ef09 rom which took away my root and custom recovery. well i went to go put custom recovery back on my transform m920 with sw upgrade. my drivers work amazingly usb debuggin on or off it doesnt matter. but in download mode my computer sees it as unrecognized device. i have not installed adb drivers due to an error: (SAMSUNG Android USB Modem Software was not installed successfully (16) there is a driver installed for the device, please uninstall it first). im running a dell 1737 laptop windows 7 64 bit and any help will be appreciated.

- Use Device Manager on your PC to uninstall whatever device is showing with the error (possibly 'Samsung ANDROID')
- Uninstall any Samsung USB drivers you have installed
- Unplug phone from computer
- Install these drivers, or Kies from Samsung
- Enter download mode and re-plug into PC
Let me know how you get on.
Good luck!

[Q] USB Device Not Recognized [Unrooted]

Hello everyone,
My pc won't recognize my samsung galaxy note 10.1 GT-N8000 *4.1.2 Android version* and also on Kies
Already tried: -Reinstalling samsung device on PC
-Restarting the device (samsung galaxy note) as well as the PC
-Kies installed
PLEASE HELP!, I WOULD REALLY APPRECIATE YOUR REPLIES
BTW, here's the screenies ↓

Try a different usb cable... Sometimes it can be that...
Otherwise re-download the usb drivers and try that.. They can be found in dev section, a quick search will find them...

The problem is that u are using a hub port on your pc or a deffective one try another one and if you have another data cable to ensure that the problem from the pc and not the tablet

If changing the cable/port did not work try the following:
1. Bring up dial pad
2. Dial *#7284#
3. Select Qualcomm USB settings
4. Make sure MTP is selected, if it isnt, select it and click ok button
5. Reboot Phone

tab 2 10.1 usb not found by computer

so im trying to root my samsung galaxy tab 2 10.1 (with http://forum.xda-developers.com/showthread.php?t=1957165), but when i boot to download and connect it to the computer, it doesnt even find it. i decided to try it normally, but still nothing.
heres a list of things i attempted to fix the problem:
downloaded kies and redownloaded the drivers
try with debugging and without debugging
change usb from pda to modem and back to pda in phoneutil
try all usb ports
its still not fixed, please help

Uninstall KIES, only use drivers e.g from here http://downloads.k0k0.de/redirect.php?r=fr_SamsungUSBDriver
Maybe Clean-Up your drivers first ( http://www.nirsoft.net/utils/usb_devices_view.html ) and reboot you PC after that, then install the new drivers.
