Preloaderk62v164bspbin: Patched Upd

: In some cases, the patched preloader allows the device to accept commands that would otherwise be rejected, facilitating an unofficial bootloader unlock.

Many modern budget phones (Tecno, Infinix) will not allow you to flash the stock ROM using SP Flash Tool without an authorized account. By loading this patched preloader as the "Download Agent" or using it in a specific boot sequence, technicians can bypass this restriction.

This research details a critical flaw where a missing bounds check in the preloader leads to an out-of-bounds write. An attacker with physical access could exploit this for local escalation of privilege.
