Build.prop gone wrong, what should i do?

[Android Central Question]

hi good day/eve, I'm prince I have an android 4.4.4 cherry mobile flare s3 octa and I tried changing my android version to 6.0 so what I did was I downloaded kingroot and root my phone so I could've access to /system then I edited the build.prop file (I changed my SDK to 29 and my Android version to 6.0) then reboot, after reboot I started panicking coz none of my apps opens when I tried opening them so what I did (out of panic) was formatting my phone and nothing happens I still couldn't open any of my apps (except for total cmd file manager for some reason) I tried rooting my phone again (using PC coz as I said if download king root or any other one click root app it still won't work coz it won't open and the last rooting that I did was wiped after the format) but unfortunately I can't (I tried shaume,king root PC, root genius etc but non of them works) what should I do? Please help and please do respect my post

PS. I need root access to re edit my build.prop file using totalcmd which is the only user installed app that can run in my phone.

P.s.s I could also run the factory apps only the user installed apps won't run (except as I said totalcmd)

Has anyone been a leader to help.you? I have a similar issue I edited my buildprop after rooting with kingroot I changed some build codes to make it think my s7 edge was a galaxy 9 for fortnite purposes.. now for some reason I went to play the game didn't work so I wanted to change my prop back to the original and it says I need root aces. MKes no sense I already rooted it so tried again and it would t root every time I install an app like purify ot supersu ot opens the app and says supersu keeps closing. So I was wondering if you had a fix for this

^ Welcome.

The poster of that probably has not registered as a member so you may be talking to the wind.
I’ll move the thread to the General Help & How To forum, where hopefully it will get better attention than in AAQ. I can’t move it to an S7E forum since the original question was about a different device.

Generally, unless you've had a few years of experience in Linux, build.prop is one of those files you should stay far away from. At the very least, before playing with it, make a full backup of anything important to you. Because now you have to reflash the phone's firmware, and that doesn't come with your files on it, so unless they're using fastboot to flash it (then you can remove the -w in whichever flashboot line it's in) you're going to lose anything not backed up. And there's no other way, unless you can root the phone in its current state.

(And using a single-click root like Kingroot is a very bad idea - for one thing, it installs stuff you don't want, in addition to the one file you do want [which is all rooting is].)
