Try to connect your Tab to PC from the KIES program in a mode of emergency restoration of firmware for 2 cases:
1. When Tab is power on (a usual mode)
2. When Tab is power on n the Download mode

Check the connector of 30 pin on your Tab with a good magnifying glass. Probably it has damage of contacts and doesn't allow to have communication with PC (it is a typical problem of this connector).

If you think you get working drivers installed, put your computer online, put your phone on download mode, plug the cable, and wait for it to install.
This is for windows 7, otherwise install the Samsung usb drivers again

That's hard.
If you do not get the PC recognize your phone in download mode, you have a real problem.
Try another USB port and cable.
Try to connect your phone to another PC.
Maybe you have to give it to a service center for repair.
Is your phone already out of warranty?
I had a similar problem where it freezes on that screen.
My problem was I installed an ICS rom with old version kernel.
Once I installed the latest CF-Root the boot was successful.
If Odin can't see your phone and you can still go into Download mode, I would check to make sure that Kies is not open and no Kies process is live (Task Manager / Processes), I think it's call "KiesTrayAgent", just kill the process and any process that has a Kies word in it.
Otherwise try another PC.

>>> Phone is supposed to be on and in download mode not off to use Odin .
Possible failed OTA update as per multiple posts due to root not removed .
Leading to USB on phone not recognized try a factory reset first .

Galaxy S3 not being recognized in odin in download mode
Could someone please assist.
My rooted Galaxy S3 phone (FW v4.1.2) is stuck at the Samsung startup screen after installing a font app from the app store
To resolve I have tried:
1. The recovery screen - doing a factory reset and reboot
2.. Reflash through ODIN.
I can get get the phone into download mode but ODIN will not recognize the phone in Download mode (Funny that phone is recognised by Odin at the stuck Samsung boot screen)
- I have unistalled and reinstalled KIES and USB drivers
- I am using the stock USB cable
- Tried different USB ports on computer
- Tried on different computers
The problem may be Windows driver related. Because phone gets stuck at the Samsung startup screen, all processes of driver installation do not conclude successful. "MTP USB Device" shows error in Windows Device manager, USB composite deivce.
Uninstalled and reinstalled these a couple of times without success.
Please assist
Issues with usb on s3
Actually fixed my own Question....
My phone was in download mode and was not being recognized by my computer my windows 7 computer. I pressed the usb icon, where a box popped up saying that there was an unknown device. You could find this in device manager.
I then went to device manager to update the driver instead of pointing the device directly to the driver when i clicked browse my computer for software then it shows a location and option to let me pick from a list of device drivers on my computer then a box pops up showing model above that there is a little check box uncheck that two boxes will appear with manufacturer and model
Scroll samsung electronics and model samsung mobile composite device that is what you want to update the driver to...
I pulled the battery then re-entered download mode and windows to over installing the rest now it works fine. I would attach images but it will not let me for some reason. if anyone can help with that I will do it later.
THIS COULD POSSIBLY help with devices not being found on computers in bootloader or just on rom loaded and running..

Hey guys, i know it's a bit late now, but i had exactly the same problem with my gt-i9300 (got stuck on samsung splash screen and odin didn't recognize it in download mode) and just realised that everytime, i connected my phone to my PC in download mode, a message would appear that "Gadget Device" (or something like that) was connected. Then i searched in my device manager for the name of it (i found it under USB-Devices) and uninstalled the driver of it. As i connected it again with odin started it would install the driver automatically and *swoosh* odin recognized it.
A year and some later after the last post and I seem to be having this problem as well... I believe it was due to a bad flash at very low battery level which ended up in encryption failure ya da da, factory reset, clear/format everything and flash custom rom from SD because any other connection would not work.... then managed to get windows (many flavors inc. 7, 8 and 10) to connect as MTP or in USB debugging mode but Odin mode (download) just won't do anything... i put the phone in DL mode, nothing happens, no windows connection sounds, no changes in devices manager, even when searching for new hardware. I'd be very interested to know if anyone has had anything like that. I'd really like to flash stock to go back to a custom rom, flash twrp to replace cwm but all seems to no avail if i can't get a connection while in DL mode.
tried to install adb fastboot but also nada since no connection is being made.... might be something with DL mode gone awry with the bad flash... long story but OTA update from current ROM decided on its own to push update even though battery was at 5% and no user interaction ever happened...
we'll see what happens...

dear friend already tried to set up a stock deodex via recovery? it avoids using Odin and will be able to install the drivers on your laptop with your connected device!
:good:

Simply download driver for samsung gti8552 and install it on the computer/laptop in which you want to connect your device for modifications/fixing.
Here is the link for the driver---> CLICK HERE
Let me know for further assistance. Thanks
Just remove your phone battery ,sim etc . then wait for few seconds and boot to recovery or download mode by only battery not with sim and sd try if this works
This happened with me then solved by this method

If download mode works , then the problem is the usb cable or the samsung driver on the PC , here is the lastest driver , If ODIN 3.10.7 detects the device try to flash TWRP-3.0.2-0 TAR as AP , if it worked reboot in recovery and the rest is up to you witch rom you gonna flash , note this is for custom roms only like CyanogenMod
Thank mate Installed TWRP and CM13, everyhing works well Changed USB cable and managed to get phone detected, quality USB cable makes difference.

Well the battery is discharged , that's why it doesn't boot , There must be something wrong or with the charger or with the usb cable , most of the time is the cable , after you manage to boot , try to flash TWRP instead CWM

Thanks for your prompt reply.
I tested the cable and charger in other phones and they work fine. In the other hand the S3 was at 30% by the time I restarted it and never came back to life. Also when I connect it to the PC there is no sign of the S3 on the device manager.

Pc don't recognize phone in download mode

Hi im trying to go back to stock firmware but my computer dont recognize my phone when it is in download mode i have the drivers installed and Samsung Kies and i have tried different cables and ports but it's not being recognized for some reason i need help
Try different USB port. And try to pull the battery out and drain all power by holding power key for a minute. Sometimes it helps expecially if u running 5.0 or higher

Did to check in device manager to see if it is not recognized?
It may be, but the driver isn't applied to the device
