SPH-L710 Resurrection Help

[PhoneSquire]

Hello All,

I have some Sprint Samsung S3 SPH-L710 phones that are hard bricked. I bought this Riff box to try to bring them back but I get this error:

Open serial port...OK
Connecting to the RIFF Box...OK
Firmware Version: 1.37, JTAG Manager Version: 1.56
Selected Resurrector: [Samsung SPH-L710 V1.0.4714.55098]
Connecting to the dead body...OK
Detected dead body ID: 0x406B10E1 - CORRECT!
Set I/O Voltage reads as 1.81V, TCK Frequency is RTCK
Adaptive Clocking RTCK Sampling is: [Sample at MAX]
Resurrection sequence started.
Establish communication with the phone...OK
Initializing internal hardware configuration...OK
Uploading resurrector data into memory...OK
Starting communication with resurrector...FAILED
ERROR: No response from the RIFF Box.

I have looked around on the forums here and the only response is to change the RTCK or TCK Speeds which I have done on every option and I reach the same result.

Can anybody help me or redirect to a solution I am in dire need here

Can Anbody help me? Is there anybody on these forums for help? If the RTCK TCK speeds don't change anything, the site says to "Check device hardware for problems." I have 5 more S3 phones that are bricked and I bought this RIff box to try to fix them. I feel like I bought this box and got ripped off.
