JCGQ20刷AX1800后TTL救砖求助

zds***

没听劝告就知道JCG Q20可以通刷CR6608结果就不知天高地厚的去试刷AX1800了  能刷是能刷但是BUG太多， CR6608的固件进不了后台 密码都是错的  AX1800的固件又无法获取SSH
于是就想到了TTL救砖 买了TTL工具以后 发现连上去和救砖教程完全不一样  因为boot loader是小米的所以TLL一直在跳码 也无法中断 找了各种教程都没用 求教大家如何救回 就想刷个pbboot就行。。

其中这两条我都试过了 毫无反应

你如果一直连着ttl的话看信息，可以看到在救砖工具链接成功后会ttl会显示进入救砖模式，载入固件后会重启，然后随便按哪个键都能进入uboot，但速度要快，不然重启完成后，之后再怎么操作都不能进uboot了，小米的固件封了ttl输入，而且会校验config分区，直接在uboot改nvram参数也没用，如果校验不通过，会启用默认设置，而默认设置是封ttl刷入的，我当时搞了挺久的，来回刷

这个我倒是没想到。我连TTL开始救砖以后确实能出现信息 但是这部分我没注意 后来刷完以后TTL就断了 系统也进不去。和官方的机器情况不一样。插拔电源重启+快速连TTL 自动发指令 无论怎么试都不行

如果直接等救砖工具刷完，那已经没法再进uboot了，ttl写入已经被锁了

按键无效的话 也可能是线序不对。。我之前搞vs010 的时候就是线序不对， 也有跑马就是停不下来。。
