Is your CRR-L09 showing errors like "Your device is corrupt" or "dm-verity verification failed" after flashing? These messages mean that the vbmeta or verified boot is damaged. In this post, we will show you how to disable vbmeta, use a custom or patched vbmeta.img, and manually replace the boot partition so these errors stop and your CRR-L09 boots normally.
Sometimes, even after flashing the firmware, the phone doesn’t turn on and only shows a black screen — this problem usually happens because the wrong preloader or DA file is flashed despite secure boot being enabled. In this guide, we will not only help you identify the correct files but also explain the complete step-by-step process to boot an MTK device and make it usable again. Every step will be explained in simple language.
