Due to some DCT4plus unlock phones issues, here is some general tip while writing unlock_img:

If your partial file is under 1mbyte - flash only it as MCU
If your partial file is over 1mbyte (like 1650) - flash it TOGETHER with PPM and CNT (otherwise - BLACK SCREEN PROBLEM!, you no need do it if unlocking old security phones like 2610 _not_ 5.65)

If your phone is DCT4Plus you need flash restore file
If your phone is DCT4.1 Costo _NO NEED FLASH_ with restore
If you will flash your DCT4.1 Costo with restore it will turn into Contact Service (normal!), and you need unlock it again
If you dont know which phone is on which CPU-type check at www.karwossuite.pl

About unlock 2630,etc
To clarify few things....
this unlock we decided not release at moment

Why?
Because this solution (same as provided by other teams) is not solution...
by relocate just simple secure rom call (0084000f) to free space in flash! (and write of course special emulator)
After unlocking we just noticed phone have problems like resetting, shutting down, etc
Thats we working now to be world's first in permament and stable solution
so you can even upgrade your phone firmware to latest ORIGINAL version
without obtaining CONTACT service as gift
