Default Flash Stock Rom from another phones backup?

OK, so my phone messed up when i changed DPI.

After few tries i end up with a blank phone.

Can only find TRE (Carrier) on Samfirmware, of course do not want a Carrier Rom.

My father has a Note 3 from Tele 2 in Sweden (same as i have) that is not locked or anything.

Can i back it up and install it on my phone then just factory reset?
Hos about the IMEI and other imported numbers?, backed them up but it was on the internal... So it is gone.

Havet IMEI from CM11 rom but i suspect it is not original.
