FYI . . . I just tried to install the new I535VRLHE radio from the goo.im link (tar.md5 file) in the op. It hung and the install failed in odin. I began to wonder if I had done something wrong, so I hopped on over to the xda site. I found one other complaint of the same hanging/failing problem when installing the HE tar.md5 file through odin. Otherwise, there wern't too many other useful comments.
If this turns out to be a problem for others trying to install the HE radio, you might want to use the .zip version and install it through recovery instead of odin. It worked for me. You can download it from rootzwiki at the following address:
[OFFICIAL][MODEMS] <VRLHE> Verizon SGS3 (SCH-I535) [ODIN or RECOVERY-flashable] - Verizon Galaxy S3 Development - RootzWiki
I've only been running the new radio for a couple of hours, so I don't have much to say about it. I did run through the basic functions of the phone and it seemed to work fine. Time will tell if I keep it or go back to the G7 version that was working fine for me.
Good luck.
