Ok, I'll try not to mess it all up this time...
Here is the link to download:
{Mod edit: Link removed. ufile.io is not accepted as file host on XDA}. That is
super.img I've created using
my script, it is packed into a tar archive and zipped to reduce the size for file sharing. It is specifically for SM-A325F, based on the NPB (Nepal/Butan) version of the firmware and contains
LiR v3.16. After unzipping it is ready to be flashed using Odin into the AP slot over the stock NPB firmware. That means, you have to
download and flash it first, then flash the
super.img. After each flashing go straight into the Recovery mode and do factory reset, only then boot the system.
But that's not all, additionally you have to extract and flash
optics.img from your regional firmware.
Here is how to do it. Changing
optics.img to your regional one is not compulsory but with the Nepalese/Butanese one you'll only have a few major cellular providers working. You can do it at any time after flashing the system, it does not require factory reset.
I have chosen the NPB stock firmware as the basis because after analyzing contents of other regional firmware I've found that it is probably the most non-bloated and privacy-respecting of all (the worst were Russian and European).
