[Q] Kies "cannot access the model information server" topic

I've been trying to update to lollipop via Kies3 for an hour or so now and i keep getting a "cannot access the model information server" error message before the update can begin. After googling the error i have disabled my firewall, tried without SD card, Sim and even tried it in safe mode with networking! Has anyone had the same issue when trying to update and if so how did you fix it?

Thanks

Kies Shows Multiple Firmwares; Old and Current topic

Hi guys,
I have an Unlocked Galaxy S5 G900H. Few days ago I flashed Argentina ROM for G900H and the process went successful. But when I connected my phone to Kies, it started showing multiple Firmwares. Then I Flashed Stock ROM back, but the multiple firmwares are still there. And as a result Kies cannot be used to upgrade or emergency firmware recovery.
Here's how it looks :


And when I click on Firmware Upgrade and Initialization, I get this:


And further proceeding with the upgrade, I get this:


What I have done so far:
Re flashed stock ROM but no luck. IF there's some special way I need to do it in odin, please let me know.
Did Factory Reset Multiple Times but nothing.
Kies is up to date. I even re-installed Kies.
I have no Antivirus Installed.

Please Help me
thanks

[Q] Firmware update failed and failed recovery with Kies topic

Hello,
I have a problem.
I used my Samsung Galaxy GT-P6800 until yesterday.
Yesterday I downloaded the latest version of kies and I installed it.
When I plugged my tablet to the program kies, this told me that there was an update available. So I accepted the upgrade.
Unfortunately not been successful upgrade. So I tried to make the recovery of the old firmware. I receveid again an error. Kies tells me to call the service center.
Now I am a tablet that does not turn on and that only goes in odin mode by holding down the power button plus the volume down button.
It should not be in recovery mode because if I try to press the power button for 10 seconds nothing happens.
How could I resolve the problem?

My tablet is not rooted.

I don't know what is the problem because doesn't compare the code error.
I do not know if it depends on the driver. I do not know if it depends on something else.
But I would like to re-use my tablet. Help me, please.
