Thanks for reply.

I had stuck then I brought my phone to service center. Cost me $7.5 to unlock and re-flash. :(

Nicely my phone unlocked and runs perfect. All phone function are just OK. With w660i featurs : )

Bad news:
- I got firmware k530i CID51 with w660 FS (wth this happen?). I checked twice with XS++ and yes, It was k530i CID51 MAIN with w660 FS. o_O

- I cannot change CID51 to CID52 with XS++ because it seems error when check validation k530i MAIN and w660i FS on my phone.

- Phone totaly locked on CID51, I cannot re-flash MAIN firmware because no k530i@CID51 :hammer:

- I cannot apply patches and update for w660i :(


need some advices, how to get my phone back to pure firmware w660i CID52?
