Unable to Update, Error - Previously Rooted

[ravenofdoom]

I have a Verizon GS5 that I previously rooted. I gave the phone to my girlfriend and factory wiped it beforehand, losing root, and now when I try to have her take the latest update that came out, it gives an update error. She had no need for root, and I hoped just factory resetting would put it back on the path without update errors. Guess I was wrong.

I re-installed towel-root and SuperSU then did a full unroot, but that still isn't allowing the OTA to pass without an error. Two things I did before I factory reset on my rooted GS5 was the SDCard Fix and Xposed + Tethering Mod. I'm wondering if those changes are still existing (even after the factory reset) and somehow the update sees those/ and stops / gives the error. Is there a way to see the update error log? (E.g. maybe root now and then undo the sdcard fix / exposed tether hack)? I'm just looking for a way to get around doing a full wipe and re-image with ODIN.

I re-rooted and looked at the logfile.. it says the update error was unexpected contents at /system/csc/feature.xml.

I looked into the file and see xposed framework and Wanam elements modified this file. I need a clean one... could anybody on the original 4.4 that came with the Verizon GS5 upload this file??

EDIT: I see now it made a .bak file there, so I restored it. Let's see if unrooting and updating will work now.

SUCCESS! It's funny how i had to root to look at the log file to find what was wrong then unroot to update. Thankfully sdcardfix and xposed made backups of the two files it modified so I could restore them so the checksum on the update would pass.
