[Galaxy S6 Edge Q&A, Help & Troubleshooting] robhuffster:
so i did not want to trip my knox and decided to use kingroot to try on 5.1.1 and when i wasnt paying attention it rebooted into download mode and installed its own recovery and tripped knox anyways. And then it failed in the middle of the flash so i reboot it and installed the g925r4 cfautoroot while on 5.1.1 and then factory reset it when it wouldnt boot.

Well its started acting weird and saying weird things about the modem every time i shut it down and also was doing logs all the time and what not and i ended up restoring stock firmware and trying to root again with cf auto root while on 5.1.1 well the second go on the cf auto root killed my baseband and sent me into a continuos bootloop unless i have a custom kernel installed, then it wont reboot. But no baseband, so no imei or anything. here is my build.prop if anyone could help, thank you.
