bypass/fix signatures do not match the previously installed version

So i need to back up app which has backup function disabled, so i decompiled app, changed backup to true and compiled, app installed and i could back it up with adb but data was gone, i needed to keep /data/data/com.myapp so i did, with pm uninstall -k and it kept data but now i can't install my modified version, it gives me error "signatures do not match the previously installed version" is there any way around this?

i don't need some root solutions, my goal is to back it up from pc with adb without root

i also tried to extract data with app not installed, but didn't work, what tells phone not to back it up if app is not installed? data itself?
