Use / 使用

1. Upload an758x-stock2ubi to /tmp on the device.
   把 an758x-stock2ubi 上传到设备的 /tmp。

Open http://<device-ip>:3333/, back up the partitions you need, and upload the matching preloader.bin or firstblock.bin together with the bl31-u-boot.fip from AN758x U-Boot. After reboot, open http://192.168.0.1/ to continue installation. The recovery page may take about one minute to appear on the first boot.

打开 http://<设备IP>:3333/，备份需要保留的分区，再上传对应机型的preloader.bin 或 firstblock.bin，以及AN758x U-Boot 的bl31-u-boot.fip。 重启后访问 http://192.168.0.1/ 继续安装；首次进入恢复页面可能需要约一分钟。

The default port is 3333; use --listen IP:PORT to change it. Startup checks for kernel release 5.4.55; --ignore-kernel-version skips that check.
默认端口为 3333，可用 --listen IP:PORT 修改。启动时检查内核 release 为 5.4.55；--ignore-kernel-version 可跳过该检查。
