FLASHING ROM

[Sheffields18]

Can, Samsung Galaxy J7 Duo stock Rom work in Huawei Y6ii, when I flash it to the Huawei using TWRP recovery in my rooted phone?

No. Roms are brand and model number specific.

Jfalls is completely right on this... Best case is it won't let you... worst case is it does, and you have to buy a new phone.

Don't be the sort of person who puts this to the test...

Yes can work.

Yes can work.

No it doesn't....

Difference in hardware is just one of the few things that would make it impossible to work. Even custom roms have to be built for each individual device.
As mentioned earlier, best case scenario is that the flash would fail. Worst case, you end up with a pretty paperweight.

Troll much?

If you do follow that advice, be absolutely sure you have a working exit strategy in place first -- any saved data has to be backed up and you need to have the stock Hauwei ROM for your phone readily available. If you just soft-brick your phone doing this hopefully you'll be able to restore it back into working condition by re-flashing the stock ROM, if you hard-brick it however, that's a lesson learned with the cost being the phone.
On the remote chance the phone even starts up running a 'foreign' ROM, don't be surprised that it's functionally unstable and a lot of basic services that just won't work.
