Samsung S6 EDGE+ (LDU - Flash stock ROM and remove Retail Mode)

Hi all,

Uninstall Retail Demo app

I found this all online named "retail demo" which I installed on my phone and now I am unable to access my settings menu or uninstall the app. When I try to to uninstall it a pop up appears that the device is locked. Is there any way to uninstall it without root access?

Wished for stock rooted ROM 4 Verizon Note 4 retail nail Dev converted.

Can someone point me to a rooted stock ROM for lollipop or better yet marshmallow for the Note 4 with the retail to Dev conversion? I didn't have the retail converted it to death using dr.cool's very well written post.now I have some emotion nightly ROM. My dream is to have a fully functional rooted marshmallow ROM. If such thing exists and can be flashed X Odin,adb or any other method with the tutorial for dummies please point me to that ROM for download. Thank you in advance. By the way this is the smn910v Qualcomm processor.
