[Defy Q&A, Help & Troubleshooting] spy king:
I have tried flashing flashing

1.JRDNEM_U3_3.4.3-36-1.7_CHINESE_SIGN_SIGNED_UCAJRDNEMARAB1B50AA03A.0R_PDS03C_USAJRDNFRYORTINT15_P002_A014_HWp3_Service1FF.sbf

2.JRDNEM_U3_3.4.3-36-1.7_CHINESE_SIGN_SIGNED_UCAJRDNEMARAB1B80AA03A.0R_PDS03C_USAJRDNFRYORTHKTW_P016_A011_HWp3_Service1FF.sbf

The last full sbf that I flashed was SEA official re-release from here

I am now unable to flash, I am getting a "Error verifying code group 33 checksums" :(

What could the issue be?
