i had flashed my k610 cid53 to w660 cid53 and everything works,,,,
the only problem is the walkman, so i need to patch it, i'm following this instructions [cid53] W660 Ultimate Guide! - SE-NSE Forums for applying patch on cid53 phones (sorry for posting link from other site)

but during applying the break file from the link an error occurred and my phone would not start and can not be detected by Jdflasher and xs++ .

what should i do now? Please help me...
