Need 5.0.2 Roms please. NOT 5.1.1. (Japan Softbank sm g952z ) Will test wrong models

I need 5.0.2 roms please.
Everyone on this site upgraded their 5.1.1 roms and completely deleted 5.0.2 roms from google.
Ive searched pages and pages.
I found one, for some g9250f model, or something, it ran GREAT, except no wifi or cell service.
even if I tried to copy paste, restore the EFS partition with my files, still it would not work.



anyone know of any s6 edge . s6 non-edge 5.0.2 roms around?
Ill be happy to settle for non Edge versions, as long as the wifi and cellular work.
I couldnt care less about fingerprints and heartrates.

I just want to get rid of this Bloat ---- that doubles the Rom size and loads up 100 extra samsung crApps

Rom Question. S6 Edge - SM g925Z Japan Softbank.

I Have the SM G925Z Version of the galaxy s6 Edge [Japan SoftBank]

I See many Roms that say "Works with many g925 Versions !" but the Japanese Z Version is never listed anywhere.
only the F T U V P etc etc versions.

If I use TWRP 2.8.6.0 to backup my current Rom, can I try these other Roms and safely return to my Stock Rom
if cell or wifi service stop working? If I try 5.1.1 Roms, I can not return to 5.0.2 roms?

Can I use TWRP to install a 5.1.1 rom that I download, even while my current Rom is 5.0.2 ?
or can I only install Roms using Odin Flash tool ?
My ZTE Warp phone was able to install Roms from downloaded Zip files with TWRP.
But I am not 100 % sure about the process.
