按照此贴http://bbs.blueshow.net/thread-1833293-1-1.html

因为版本是s0018,自己修改了104shunlock.c 运行如下
# /data/local/tmp/104shdump
/data/local/tmp/104shdump
open ok(3)
mmap ret=0x10000000
Miyabi Unlock!!!
NAND_LOCK Unlock!!!
Killed

接着 su写入我不怎么懂,网上找了一段代码 运行如下:
# mount -o rw,remount /system /system
mount -o rw,remount /system /system
# chmod 777 /system/xbin
chmod 777 /system/xbin
# cat /data/local/tmp/su > /system/xbin/su
cat /data/local/tmp/su > /system/xbin/su
/dev/sh: cannot create /system/xbin/su: Read-only file system
到此就不行了,有时候后能写入su,用re看得到文件,但是一会就没了。然后在执行
# mount -o rw,remount /system /system
就显示
# mount -o rw,remount /system /system
mount -o rw,remount /system /system
mount: Read-only file system

请问这是怎么回事?
