看这个wiki的帖子照着步骤一步一步来，虽然是英文但是单字都不难。
论坛上提权的教程，我都遇到permission denied的问题，但是经过这个网站上一步步的来，终于获得权限，刷了一整天，皇天不负有心人。
跟大家一起来分享一下

我找到最致命的让很多人su 拒绝的最主要原始是少了以下这段
If you're having problem with signing in to Google at the Setup Wizard, here is your solution:

Downgrade the firmware
Copy the desired recovery image to the root of the SD card, name it recovery.img
Enable WiFi connection and connect to your local home network: Windows or Linux
On the Android screen, type this: <enter>telnetd<enter>
On your PC, open a new Command Line (Win+R, type cmd<enter>)
On the device, press on your connection to know your local IP
Back on PC, type this to the fresh command line: telnet [your_local_ip]. This should connect you to the device, and you should see this: # #
If it's right, copy these lines and press enter on the end of them:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
dd if=/system/bin/sh of=/system/bin/suchmod
4755 /system/bin/su
Now let's try it. Type su in the console. If it says nothing, but opens a new line (# #) then you're good. If it says "permission denied", repeat step 8.

只要这段你能过就说明你得到su的权限，剩下的就小菜了，不过很多网站上的刷机方法都没提到这个。
