I followed the second method (Odin), and everything went fine. Wifi is working properly and the battery life is great. The issue I have is that unlike the Roms you posted for the Verizon (i545) which I flashed today as well I found out that by using the Odin method on the L720 my KNOX counter went to 0x01. I know you didn't specify that by flashing the ROM the Knox counter would change, so I mistakenly assumed (since I flashed your i545 ROMS) that there would be no problems with Knox.
Anyway it really doesn't matter because I have had the L720 for close to 2 years and by this time there is no warranty to speak off, but I think you might want to update the OP to let others know that by flashing the ROM using the Odin Method their KNOX counter will change.
Question... Do you know if maybe the reason for this is that I used Odin for the L720 and on the i545 I used Flashfire instead. Perhaps Flashfire might be the prefer option for those that do not want their Knox counter to change (assuming Odin was the culprit)
Thanks.
