<P>其实方法很简单的和刷ROM一样<BR>首先得备份你机子原来的radio，用romupdat备份，在open port setting里输入 d2s 60000000 00300000 回车，就会得到备份，然后读到PC上，用Hexeditor复制头416个字节，然后再改写你下的1.13 radio映像文件。再写回到sd卡上。这次boot后，出现Press Power to flash字样，按下电源键后，开始下载新的radio，在屏幕底部有Radio ROM Updating....，最后屏幕出现Download Failed/Checksum Fail<BR>再重启818，可以看到radio已经升级到了1.13.00。</P>
<P>备份和写入SD到PC，具体的方法可见我的818升级的帖子这里就不说明了<A href="http://bbs.blueshow.net/read.php?tid=145400&fpage=1">http://bbs.blueshow.net/read.php?tid=145400&fpage=1</A></P>
