Root Flashing Rom Failing In Philz Recovery?

[axelxbc]

So I did search, and have been searching for awhile for this before coming here and posting. Have only found vague answers in other forums (Or outdated ones).

Before I start I want to Mention, I do not care if KNOX gets tripped, I have already updated to the most recent Bootloader with KNOX, I believe it is 4.4.2. Already updated my modem to the ND8.

I have flashed TWRP 2.8.6.3 using Odin.

Every time I try to flash a new Rom with Philz Recovery I receive a Failed Cannot mount '/system' And of course displays the failed at the top of the screen. I have already used this Rom before with the older Bootloader, but I was under the impression you can still flash Roms even after upgrading to the new Bootloader? What am I doing wrong?

If I have to downgrade to the older Bootloader, I will do that, but when searching for the firmware I could not find that either. Only found the stock Sprint Firmware.

Thanks for all the help in advance, I am really new at the New Bootloader, and KNOX stuff.

*EDIT
I am On Virgin Mobile Model: SPH-L710

I did not find a way to delete this thread. The issue was it had a "Error executing updater in binary zip". Downloaded a newer version of the Rom and it worked. It happened with two of my Roms, which were different, so I thought it was a Bootloader, or Philz Recovery Error.

So problem fixed! Delete Admin.
