分辨HG255d uboot 是原版 还是修改版，其实很容易。
1. 设置本地连接为 192.168.1.100 mask 255.255.255.0 网关不填，DNS不用填写，网线与hg255d连接好，保持机器关闭状态。
2. 先在浏览器输入 http://192.168.1.1/upload.html，然后按住路由的reset键并接通电源，保持reset按住，浏览器不停刷新这个地址，大约几秒左右就可以看到如图所示的界面：
3. 能看到上面界面的就是电信原版uboot，刷新出不来这界面的就是改版的uboot。
4. 最后大家可以去试试这方法，看看自己机器的uboot到底改版了没有。

Since you’ve got the backup, it’s actually pretty simple. Just restore the backup files to your new flash drive, then head over to the /config directory and edit the go file. Look for export UNRAID_GUID=xxxxxxxxxxxxxx and swap it with your new drive's GUID. That should do the trick!

Really apreciate for your fast respond, mate. I actually have the backup of the flashdrive (from regular unraid backup). The problem is, when i search on youtube tutorial about changing the failed flashdrive, the process need some sort of confirmation with an account in unraid (blacklist the old one -> whitelist the new one). Since i have a cracked unraid, i don't know how to register my new flashdrive as the correct one (and the system not asking me for the old failed flashdrive). Thanks in advance

Man, that's a tough spot to be in. Regularly backing up your /boot folder is super important for exactly this reason.
If you don't have a backup and your flash drive is completely fried, your best bet is to Google some specific recovery guides or check the Unraid forums. There are ways to rebuild your config by identifying your parity and data drives, but it can be a bit of a process. Hope you can get it sorted!
