Your console isnt mechapawned. It seems that someone soldered PMAP and made full console reset via command c8d00. Currently, mechapwn cannot do anything with such consoles, I didn't implement emergency nvram restore for erased consoles. It is planned feature, as already many people ask for it, I will try to implement it but I cannot tell when it will be done.

您的控制台不是 mechapawned。似乎有人焊接了 PMAP 并通过命令重置了整个控制台c8d00。目前，mechapwn 无法对此类控制台执行任何操作，我没有为已擦除的控制台实现紧急 nvram 恢复。这是计划中的功能，因为已经有很多人要求它，我会尝试实现它，但我不知道什么时候会完成。

@AKuHAK 非常感谢，我现在无法使用硬盘fhdb

@leonda2008 you can test this build. Place attached nvram backup into your usb root (rename or remove old file or use another usb). nvm_5.04_16777215_fixed.zip And try this mechapwn build (download in artifacts section). Select Restore Backup option. I kindly ask you to make pictures of the whole process: if something will go wrong (build is completely untested) so you can provide them. Keep in mind that you will be forced to unplug electricity twice.

After restore you can try installation again.

不行，没有提示恢复固件，一直提示按x继续，拔掉电源线重新开始mecha，一直循环。
