Thanks for posting your question Jniede.
I am having the same issue exactly.
I upgraded the stock firmware after I bought the phone and
I'm wondering if that is related. Did you upgrade to the latest stock firmware before attempting
to flash?
Edit: According to an earlier post in this thread by EndlessDissent it shouldn't matter which
firmware is on the phone. So maybe that's not it.
Edit2: a more recent (2013) post by toeshot
(

says "once you install the 4.3 update you cannot use Odin to flash a downgrade ROM even an official Samsung ROM." so maybe that is it...
I don't have any more time to mess with it right now I hope some of this information is helpful.
I am currently digging around for a solution.
My Odin log is identical to yours and now my phone will only boot into download mode with an error.
The error states "Firmware upgrade encountered an issue. please select
recovery mode in Kies & try again."
Edit2: At the top of the phone it states:
SW REV CHECK FAIL : Fused 1 > Binary 0
Which firmware did you attempt to flash? I tried the latest one in the OP.
"root66_SPR_L710VPBLJ7.tar.md5"
I was going to try and flash the "L710VPALI3" one but I don't have a decent internet connection to
download it on.
Have you tried flashing one of the other images?
