Hi [MENTION=4277844]chenxiaolong[/MENTION] , I got a problem: I can NOT flash zips patched by DBP(v9.1.0).It prompts a warning: not running under u:r:mb_exec:s0 context.

Flashing ROMs patched by earlier DBP is OK; Flash zips patched by DBP(v9.1.0) under TWRP failed, prompt: Can not run real update-script.

Device: Oneplus2 A2003

Tried DBP in: AOSP-CAF 6.0.1,CM14.1
