中兴机顶盒b860a s812版本刷机求助
本帖最后由 智能小柠檬 于 2022-2-21 13:17 编辑论坛的教程都是全砖可以线刷，或者能进系统开ssh和abd连电脑。我的盒子刚好是介于这俩个之间，因为上家刷机失败，可以进rec，但是双清也无法进入系统，缓存文件夹固件文件夹都被破坏了。
ttl被锁定无法输入，所以无法开启线刷模式。
卡刷模式同样因为无法输入，无法完成命令。求助。
救砖联系我 求助这个盒子的短接点在哪里 用全砖方法试试 leidada269 发表于 2022-2-21 13:46
用全砖方法试试
当然试过，连不到电脑。因为不是全砖
歪打正着进了线刷模式，求固件，网上能找到的固件都刷不过去。 短接点r23
