[G900P] "Unfortunately, System UI has stopped" after installing xposed framework

I recently installed the MOAR rom on my 5.0 on my G900P since the rom is deodexed and to install xposed, you need a deodexed phone. I flashed the xposed-v75-sdk21-arm-arter97-snapdragon.zip from http://forum.xda-developers.com/xpos...lipop-t3113463 and when I reboot my phone, I get the error (did I install the wrong zip file?). I've tried clearing the dalvik cache and cache partition (I get an error when trying to clear the cache partition), and none of these have worked. Is there anything I can do to fix this, or should I just not install xposed? Thanks.

EDIT: I flashed the uninstaller provided by rovo89, but I still am having the same problem. I also get the error "Unfortunately, the process android.process.acore has stopped."

Flashing G900P Firmware on G900F Device

Hi! I've been using CM13 for my device until recently when I decided that I would like to go back to the stock samsung ROM. Having decided, I've tried to flash the SM-G900F firmware through Odin but it didn't work; I've tried 4 different firmware packages from different countries and android versions, yet they all resulted in failure. My phone is currently soft-bricked with access to (stock-samsung) recovery and download mode.

I've noticed, however, that on the back label, my device is the SM-G900F, but in download mode, it reads SM-G900P. I figured that maybe the Odin flashes were failing because my device is actually the G900P. I was wondering if I could try flash the G900P firmware through Odin, but I'm hesistant. If the flashing fails, will my device be hard-bricked?

Can G900P use a GSM SIM card for data?

I want to use a FreedomPop SIM card (T-Mobile network, I think) in my G900P for cell service, but I can't seem to get it to work.

With the phone stock, it displays the message "Invalid SIM" after inserting the SIM card. Switching to GSM doesn't seem to help. Also in the stock state, the phone displays "UNBLOCK" under the *#0011# info, and never asks for an MSL code (which I have).

I rooted the phone and put Cyanogenmod 13 on it, but still can't get GSM service. Cyanogenmod doesn't warn that the sim is "invalid," but even after setting to GSM mode (using *#*#4636#*#*), the network just won't connect.

(I also manually set the APN with everything I've tried.)

Is this phone even capable of using its SIM slot for GSM?

Thanks
