[HELP] unrooted phone without uninstalling xPosed

Hi, I have a Wiko Highway that I want to send to warranty.

So i had my phone rooted, and unrooted it and then factory reseted it, but i forgot to uninstall xPosed and its modules.
Now i started to install some apps so i dont send the phone empty, and when installing snapchat it wont let me login (as it block's rooted phones)
So, by some way snapchat "thinks" i'm still rooted, i'm afraid the provider can tell that :/

Is there anyway to prevent this?

Thanks

How to get rid of twrp recovery completely on galaxy s4 after uninstalling twrp app?

Hi! I was wondering if you can get rid of twrp recovery comepletely on galaxy s4. I am in need of sending my phone to repair because of the damaged sim card tray or reader after i forcefully forced the nano sim card which is supposed to be micro sim card in and force it out which damaged the sim card tray/reader.

Although because the galaxy s4 was another countries model, my own country(singapore) samsung service centre did not count the warranty as valid and refuse to fix it without a fee and i was thinking of fixing the warranty to bring it back to where i bought the phone first from for them to fix since they apparently have their own store warranty and i bought the phone last year first of july.

How to fix it with It being android version 4.3 and with the set warranty bit:recovery,how to fix it for my in case warranty to be valid? I have uninstall twrp app from my phone in googleplay and have flashify back the stock kernel and the SElinux i think.
