我的砖头最早的状态是插电后灯一点都不亮,按住reset键再插电也没有一点效果。于是去买了TTL转USB,3.3V电压,ax3000t只需要拆下后盖即可看到,不过因为没有出厂事先焊好排针,就自己想法子对其那4个洞插入就可。
拆下后盖,在靠近电源的位置有4个洞,从上往下分别是VCC(3.3V)、RX、GND、TX。使用xshell进行串口连接,接口应该是COM3,波特率选115200,插电即可看到输出信息,我的在帖子一开头就是最早的输出信息。

参照楼上大佬给出的https://www.cnblogs.com/p123/p/18046679。分别下载了mtk_uartboot.exe、mt7981\mt7981-ddr3-bl2.bin和一个uboot,然后按文中方法刷入,输出信息基本和文中一致,刷完后砖头就开始亮红灯,此时赶紧用xshell连接,按下任意键(建议除了enter键)就可以停止启动 (autoboot),可以看到uboot启动菜单,分别选择升级刷入bl2和fip。这两步类似,在windows本地起一个tftp服务器将要刷入的文件放入tftp服务器目录,砖头与windows连上网线,Windows的ip配置为192.168.1.2,掩码255.255.255.0,网关192.168.1.1,启动tftp服务器。回到xshell选择tftp client分别输入ip和文件名之类即可刷入,刷完之后按下任意键(建议除了enter)就可以停止autoboot(这步比较重要)。两个都刷完,最后再刷入固件(同上两个一样)就可以成功救砖。
