Have you tried using UFS box as J4F interface and see if you then have an error?

Yes Odia, I have tried & still get cert mismatch error when flashing. I use 7 pin cable aswell. On some of the phones eg. N70 when you still get 2nd boot err cert mismatch & flashing error on J4f aswell even if the regulator is 3.0v & using a 7-pin cable & dual-line is selected, I have been told that its the flash ic that is faulty. If reheating the flash ic does not help, you have to change flash ic.

Thanks for the reply, but I was talking to mail0 and their situation.

Yes what you have been told is right, it could be an issue with Flash IC, cable or another voltage issue, the regulator is not the only cause of this error and really all other factors should be ruled out first, unless of cause the regulator is incorrect, then it would be best to correct it anyway.
