Help Firmware upgrade encountered as issue

[trickslk]

I recently brought a tmobile unlocked, Samsung galaxy s3, T999.
I tried to upgrade firmware with samsung keis, but it stucked at 0.
Then I tried, Emergency Firmware Recovery, it also got stuck.

I rooted it and applied a custom rom, CyanogenWIZ(Found on xda top review rom)
Then i wasnt able to turn on wifi, SIM not detected, etc.

Then I wiped all data, reset the phone.

It didnt goto the home screen, stuck at loading(with that google 4 colord dots).

I could ONLY access, Recovery Mode and Download mode properly.

THEN

Finally was able to reinstall the stock rom,

Galaxy S3 Stock Firmware | Galaxy S3 Root
T-Mobile Galaxy S3 Stock Firmware MD5

T999UVALEM_T999TMBALEM_T999UVALEM_HOME.tar

After that, It loaded all those "Android 4G tMobile logo, Samsung Galaxy S3, that green animation"

But it didnt go further than SAMSUNG logo with blue animation thing.

I installed the,

[Stock][ROM]Galaxy S3-LTE (d2ltetmo) - xda-developers

*****ODIN Firmware*****

First, Recovery, then Stock Kernel.

Now, IT says,
"Firmware upgrade encountered as issue. Please select recovery mode in Kies & try again."

When I press the turn ON button.

Cant access recovery mode. But download mode can be accessed.

PLEASE HELP ME< I REALLY NEED YOUR HELP.

Try using Odin on the 4.1.2 May 2013 build at Firmwares | SamMobile

BTW, did you see the following notice on the LTE Demo ROM? "NOTE: It is CONFIRMED that the T999L modem, does NOT work on the original T999. It will not brick the device, but you will have no connectivity."

If the stock ROM doesn't fix things, you may have to send the phone back to Samsung.

Surprisingly Kies saved me!!! I just fallowed the youtube channel for samsungservices under Using Kies Software Recovery Tool". This will factory reset and wipe data. Open Kies, click tools tap at the top of the screen, then click firmware upgrade and initialization. Turn off device and remove battery to see serial number MEID or in my case I used HEX number) and model number. type them in the appropriate spaces. reinstall the batter cover and connect phone to computer. It took about 10 min to finish and restart my phone. click okay a few times and check the read caution and check yo agree to terms to start the process. it took my S3 7-10 mins. BTW it may seem like its not moving after the download software stops but wait a few and you will see the up load arrow,

I had the same issue, when I started the steps above Kies never said my device was connected. But I just let it go through the whole process with out touching phone or computer.
