MB526 Defy plus flashing problem

[kwaku85]

Hello!
I have problem with MB526, I have flashed this phone with same version of firmware, and then- died. A was try similiar versions, but same problem. Still dead (only flashing mode after power on). And then I decide to flash never version (latest on support):
DEFYPLUS_U3_4.5.1-134_DFP-231_AR_SIGN_UCADEFYEMARAB1B80AA004.0R_PDS03C_USAJR DNGIBRRTARAB_P016_A027_M001_Service1FF.pcf
Phone back to life, but have no Polish lang. Any other version make phone dead again. Can You help me somehow?
And what's the difference between those 3 types flash on support?

Can you post here exact firmware version that this phone had had before you flashed it?

They intended for flashing Defy for different regions, for example, DFPRC_U_4.5.3 - most possible that this firmware is for Chinese Defy.
In nine cases of ten, cross-flashing not allowed by the phone and can cause it's brick.
