[ 12.353452] init: cannot find '/system/bin/surfaceflinger', disabling 'surfaceflinger' Step 1 – Bypassing Preloader Authorization Huawei’s Lua-L02 uses a signed Preloader that rejects SP Flash Tool’s default DA. We used a patched DA file ( MT6735M_DA_PL.bin ) with a brute force handshake script. Step 2 – Scatter-Loading & Partition Table The firmware scatter file revealed critical partitions:

$ md5sum system.img a3f5e2c1b9d8f4a2... (matches stock firmware hash) The MT6735M has a BootROM vulnerability (CVE-2021-0312, MediaTek BootROM Info Leak) that allows DA download even if the preloader is corrupt. By pulling the BOOT pin to GND during USB insertion, we force BootROM into download mode without preloader execution. This allows SP Flash Tool to write a clean preloader and boot chain. 7. Conclusion The "Dead Hang Logo" on the Huawei Lua-L02 is fully recoverable without JTAG or eMMC reballing. The key is forcing preloader bypass, using a scatter-accurate DA, and selectively rewriting only the corrupted partitions. This case demonstrates that MT6735M devices rarely suffer true hardware death; rather, they suffer metadata corruption that mimics hardware failure. By pulling the BOOT pin to GND during
