So last night i installed a custom rom for my s7 edge to try if its stable and then when i see that its not stable i donwgrade it quickly but the thing is that the downgrade failed because the error saying "sw rev check fail device 4 binary 2" andni know there is something wrong with either of the bl,ap,csc and i know that error says that either your using the wrong file or your using the old file but as i know thats the latest file update for my phone i just downloaded it, so no i dont know what to do and im stuck on the unstable custon rom that i installed, pls help asap. Thank You
