What will happen if I flash a custom rom for GT-I9082 on a GT-I9060c/m/i? I have a Samsung Galaxy Grand Neo Plus/DUOS (GT-I9060C) and I would like to know what will happen if I FLASH A Custom Rom for the Galaxy Grand Neo DUOS (GT-I9082) Onto my phone (GT-I9060C)

Will it be Hard-Bricked,Soft Bricked or will it work fine

Custom ROM description : Lineage OS (Android 7.1)
Linux 3.0
Supports dual sim

Current rom: Rooted Stock rom 4.4.4 kitkat SuperSU  Pro running TWRP 3.0 For GT-I9060I (idk how gt-i9060i twrp recovery worked on the gt-i9060c
With AKAS security software (idk what that is)



Hmm So if i did flashed the rom and its soft bricked (repairable) will i still be able to use DownLoad Mode because i heard some people said that it will hard brick your phone (unrepairable) if you install roms that wasnt met for your phone. Also im on GT-I9060C not on GT-I9060I because i9060i doesnt have a magnetic sensor

Heres some description about my phone:
The similarities of the 2 devices are mostly only in their name. Grand Duos (i9082) is out Jan 2013 and uses a Broadcom BCM28155 SoC, while Grand Neo Plus Duos (i9060i) along with its family are out circa 2015 and use a Broadcom BCM23550 SoC.

Recovery will reject ROMs made for a different device, and even if you manage to flash it in, it won't boot due to the hardware difference (soft-brick in your words).
