Summary

Analyzed USB capture from official flash tool for MT6768 (lamu/Samsung A15) to verify chipset support. Existing configuration for hwcode 0x707 is complete - no changes required.

Analysis

USB Communication (1.pcapng, 163MB):

  • VID:PID 0x0e8d:0x2000 → already in usb_ids.py
  • Standard MTK preloader protocol with "READY" handshake
  • hwcode 0x707 (MT6768/MT6769) → fully configured in brom_config.py

Exploit Compatibility:

  • Kamakiri exploit with var1=0x25 → configured
  • All BROM addresses verified (watchdog: 0x10007000, uart: 0x11002000, etc.)
  • Payload mt6768_payload.bin exists

Changes

  • Added mtkclient/Loader/Preloader/preloader_lamu.bin - device-specific preloader (322KB)
  • Added MT6768_LAMU_ANALYSIS.md - detailed USB capture analysis documentation

Files Analyzed

  • DA_A15_lamu_FORBID_SIGNED.bin (625KB) - DA agent
  • preloader_lamu.bin (322KB) - preloader binary
  • 1.pcapng (163MB) - USB communication dump

No configuration updates needed - lamu variant uses identical hwcode 0x707 configuration as other MT6768 devices.
