现在是PandoraBox-Boot，进TTL报错信息如下：

华硕NVRAM v0.08 可用空间：131072。完整性：签名失败！
end_request：I / O错误，dev mtdblock4，扇区0
SQUASHFS错误：squashfs_read_data无法读取块0x0
SQUASHFS错误：无法读取squashfs_super_block
VFS：无法打开根设备“ mtdblock4”或未知块（31,4）：错误-5
请附加正确的“ root =”引导选项；以下是可用的分区：
1f00 256 mtdblock0（驱动程序？）
1f01 512 mtdblock1（驱动程序？）
1f02 5376 mtdblock2（驱动程序？）
1f03 124928 mtdblock3（驱动程序？）
1f05 512 mtdblock5（驱动程序？）
1f06 512 mtdblock6（驱动程序？）
1f07 107520 mtdblock7（驱动程序？）
1f08 16384 mtdblock8（驱动程序？）
内核崩溃-不同步：VFS：无法在未知块上挂载根fs（31,4）

复制代码

一开始是按照https://it.ismy.fun/2019/05/16/xiaomi-router-3-flash-pandora-firmware/的教程刷的，刷入bootloader后直接重置摁住重启，导致变砖。购入TTL之后按照https://openwrt.org/toh/xiaomi/mir3的救砖方法和https://www.right.com.cn/forum/thread-342165-1-1.html的救砖方法均无效，初步判断是因为他们是U-BOOT，而我手的这个已经是PB了，所以照搬无效，求大神给个刷机思路。

具体启动日志如下

rootfs物理地址错误，所以无法读取，虽然重刷已解决，但NAND闪存可能存在坏块或不稳定，难保问题不会再发生，如果坏块出现在rootfs，那就必须借助 "initramfs"

小声补充一句：我迟迟不敢刷pb-boot，因为已经看过不少杯具，此外，没有适配小米路由器3的Breed也是让我不敢折腾Bootloader的原因
