A Journey Through DM-Verity and Bootloader Challenge

I recently needed to program a certain phone—specifically, root it or at least unlock its bootloader. But here’s where the fun began: I couldn’t unlock the bootloader.

Sure, I could blast it with MTK Client, but the moment I did, the phone threw a DM-Verity corruption error. Fastboot flashing or OEM unlocking? No luck—the volume up key wasn’t responding.

“Just flash vbmeta!” they said. Great advice in theory, but flashing vbmeta using SP Flash Tool or MTK Client didn’t work either.

“Try fastboot with the DM-Verity vbmeta command,” they suggested. A solid idea, except… I couldn’t even boot into fastboot because the DM-Verity screen blocked me at every turn.

I tried everything: editing the little kernel, tweaking the boot image, but nothing worked. Even changing a single hex digit in the code triggered a DM-Verity error.

That’s when a great guy—a legend in his own right (and chasidish :muscle:)—came to the rescue. His advice?
“Use Autobooter.”

Autobooter is a straightforward tool that essentially forces MTK devices into fastboot mode. With that, I was finally able to bypass the roadblocks. The Tiq M5 is now happily running Android 14 and currently testing Android 15. Exciting stuff ahead, folks!
