Nokia 3660 to 3650 and back!!
 

Today by mistake :D I transformed Nokia 3660 to 3650, I was "contact service" and I flash it like 3650 :D , and here is how to do it, and files which you need!!

3660 to 3650
1. erase flash with attached files (erase 3650)
2. flash MCU & PPM for 3650 (i flashed with version 4.13)
3. write PMM & unlock phone
Now you got working 3650 only thing that only some keys are working because you need to put keys from 3650!! (This is the point when I find out that I flashed 3660 with 3650 flash!)
Maybe if you write PMM from 3660 keys will work but after all I did, I didn't want to try that!!

So now I had to convert it to 3660
1. erase flash
2. flash MCU & PPM with flash for 3660
3. write PMM & unlock phone
And again 3660 is working!! :D
