[Radxa Rock]变砖后如何恢复

是否变砖?
使用RKBatchTool当写入 update.img 到NAND  失败时提示下面的消息: “Prepare IDB Fail” (或者使用其它工具写入NAND时提示类似的错误消息 )
Radxa 变砖了。实际上它没有真的变砖,此时启动引导(BootLoader)被破坏,你可以总能恢复它。
要恢复它:

  1. 关闭电源.
  2. 用针连接NAD上的针脚 8 和 9 并且插入 OTG USB 线到计算机.
  3. 断开针脚连接. 在 RKBatchTool 里方框里应该变蓝(如果没变蓝,重试).
  4. 单击还原按钮并上传一个 update.img

提示

  • Its useful to use a magnifying glass or (smartphone-)camera zoom to get the right pins.
  • Always start counting pins on the edge of the chip where the small circle is molded in or printed on.

If you see Maskrom(Normally it’s Loader), that means you have successfully short cut the nand flash.
