Parts of 4.4.2 rom to 4.3 possible?
since i have a problem with bt in 4.1.2 and 4.3 rom and solved with 4.4.2 i am wondering if the part of bt in 4.4.2 can be merged to a previous rom.
i dont know if its driver or something else. i tried to copy every file i saw in 4.4.2 which said bt to 4.3 rom but then bt didnt work.
yes i did not had hope about that, i m not developer i had to tried it.
could someone answer me if its possible ?
