河南联通IPTV盒子B860AV2.1U刷机及覆盖密钥问题

刷了一个不知道管用与否的IMG里边有个LICENSE文件夹还让放到刷机工具目录 然后勾选FLASH BOOTLOADER 覆盖密钥三项 刷过之后重启 无限重复ZTE画面无奈准备重刷   然而再刷其他IMG全部卡在1%Romcode/初始化DDR/下载数据/读取镜像失败
哔了够了望大神们解释一下覆盖密钥是什么意思？？ 是不是有加密一说？？

之前刷过2、3个包 都可以 但感觉不理想后来又刷了一个 其中有一个什么SECURE_BOOT的文件 勾选了是否覆盖密钥后来提示刷成功   然后盒子就一直重启表现为开机画面一闪就黑屏然后继续开机画面闪 一直循环
