【已解决】求助 AX6变砖 TTL修复 过程会自动关机或死机

mingpcer

各位好，请问下懂的坛友，
砖了，先用小米修复工具，刷官方固件后会蓝灯闪烁表示成功，但开机仍然亮单橙灯，久不久闪一下，
用TTL救砖，启动后按回车中断uboot启动，

Writing from /tmp/.mtd_crash_tmp to crash ...
Log saved to crash.
FATAL: Data mount fail again. Restoring defaults.
ubiattach: error!: strtoul: unable to parse the number ''

[    9.187349] UBIFS error (pid: 209): cannot open "ubi1_0", error -19tach: error!: bad MTD device number: ""
mount: mounting ubi1_0 on /data failed: No such device
[    9.252

跑码到上面这就会关机或死机了，灯不亮，

系统：Win 10 64bit

USB转TTL设备：CP2102

试过换USB口2.0 3.0，更新CP2102驱动至03/28/2016,6.7.3.350等都一样，

已解决，第一次用TTL，就遇到这种不能中断的问题，蛋痛！搜很多资料后一步步知道问题和解决问题的方式，有空时分享下。

可以试试更换usb驱动器，建议使用CH340G或FT232RL的usb转接器，不行就没办法了

求助楼主，你是怎么解决的？我目前和你情况一样，用小米修复工具成功，但启动后还是橙灯。

同楼主的问题，无法中断进uboot。后来用小米修复工具成功刷一次，再重启就能进入uboot了。
