But as logs say that phone has DFL61_HARMATTAN_40.2012.21-3.265.6_PR_265 -> 40.2012.21-3 means PR 1.3 version if the Mexico variant, which means that DFL61_HARMATTAN_40.2012.21-3.420.4_PR_LEGACY_420_ARM_RM-696_PRD_signed.bin actually has older sw cert timestamp. Mrcrab is missing the link to 265 PR1.3 version, so you either need someone with the bin or sw variant with newer timestamp.
