[Galaxy S 5 Q&A, Help & Troubleshooting] learning1:
I have testing every rom I could find on my G900W8 and below are the results

Custom ROMs have 2 issues with the G900W8 .

-Fingerprint Scanner Support

-LTE Band Support - 3g is slow and LTE not functioning properly is slow also)

TESTED RESULTS

If you use the ODIN MOBILE G900F flash method you will likely trip your KNOX.

If you follow these steps exactly you will not. *** The rom will not work well

Flash all with Mobile ODIN from rooted 4.4.2 (towelroot + super su for knox 0x0)

G900FXXU1BOB7_DevBase_alexndr.zip

BL_G900FXXU1BNL9.tar.md5

CP_G900FXXU1BNL9.tar.md5

Any other solution will set your KNOX to 0x1

If you want to maintain your Samsung warranty and KNOX 0x0 stick with 4.4.2 until a fully tested ROOT method for 5.0.0 Lollipop is working.

If you want custom ROM the following works well.

TWRP Recovery working ok

openrecovery-twrp-2.8.5.0-gt-klte.tar

Philz Touch working ok

philz_touch_6.57.8-klte.tar.md5

BEST SOLUTION for LOLLIPOP (KNOX Will be 0x1)

Odin 3.0.9 use AP (to flash)

Update to Lollipop (G900W8VLU1BOB3_G900W8OYA1BOB3_G900W8VLU1BOB3_HOME.tar.md5)

Install Recovery -> openrecovery-twrp-2.8.5.0-gt-klte.tar

Root -> UPDATE-SuperSU-v2.46.zip from SD Card using Recovery

** Use app like titanium backup to FREEZE ALL Samsung or other Pre-installed apps.

** edit CSC files manually if you want extra features.

WARNING for XPOSED Framework 3.0.alpha2 in Lollipop stock ROM

At this time from my testing

xposed installer alpha1 and alpha2 is bootlooping the G900W8 with stock rom.

BusyBox Pro also has issues installing Busybox at the moment on Lollipop stock rom
