-再一次强调,请先查看 [[docs:techref:flash.layout#Details]],并注意[[docs:techref:bootloader]]分区和''ART''、''NVRAM''等等小分区没有包含在OpenWrt固件。因而某些错误导致这些分区数据被损坏,将不能恢复它!你的机器可能已经无法启动,你不得不去论坛问其它人要这些分区的备份,然后发送给你,你还要替换MAC地址然后通过 [[docs:hardware:port.jtag]] 恢复。+再一次强调,请先查看 [[docs:techref:flash.layout#Details]],并注意[[docs:techref:bootloader]]分区和''ART''、''NVRAM''等等小分区没有包含在OpenWrt固件。因而某些错误导致这些分区数据被损坏,将不能恢复它!你的机器可能已经无法启动,你不得不去论坛问其它人要这些分区的备份,然后发送给你,你还要替换MAC地址然后通过 [[docs:techref:hardware:port.jtag]] 恢复。

-如果bootloader分区损坏,不会有 [[docs:techref:bootloader#additional.functions|booloader console]],只能通过 [[docs:hardware:port.serial|Serial Port]] 连接 [[docs:hardware:port.jtag|JTAG Port]] 来恢复或焊下flash芯片,参阅 [[docs:guide-user:troubleshooting:generic.debrick]] 获得帮助。+如果bootloader分区损坏,不会有 [[docs:techref:bootloader#additional_functions|booloader console]],只能通过 [[docs:techref:hardware:port.serial|Serial Port]] 连接 [[docs:techref:hardware:port.jtag|JTAG Port]] 来恢复或焊下flash芯片,参阅 [[docs:guide-user:troubleshooting:generic.debrick]] 获得帮助。
