1台OS 3.0的水果机
1个官方2.2.1的固件 (下载地址:http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-5830.20090127.Mmni6/iPhone1,1_2.2.1_5H11_Restore.ipsw
1个2.2.5-2的QUCIK PWN越狱软件(自己找地方下载吧~太多了,都可以用的)
i tunes 8.1版本(这个也非常多)

步骤:

1. 控制面板-添加/删除程序-卸载4个软件,分别是:Apple Mobile Device Support, Apple Software Update, iTunes 和QuickTime。


2.用WIN+R快捷键输入regedit,打开注册表。将HKEY_LOCAL_MACHINE — SOFTWARE下面的Apple Computer和Apple Inc. 点击右键删除
将HKEY_CURRENT_USER — SOFTWARE 下面的Apple Computer 点击右键删除

3.在C:\Documents and Settings\(你的电脑名字)\Application Data\这个目录下找到Apple Computer文件夹,将其删除。在C:\Program Files\这个目录下找到Apple Software Update这个文件夹删除。(以上方法取自《教你安装低版本iPhone同步软件iTunes》-,谢谢原文作者)


4.安装你下载的ITUNES8.1,重启电脑。


5.确保电脑里面是纯净完整的8.1 ITUNES后,接上你的IPHONE(再次提醒同学们,备份好)然后它会提示你无法读取,必须升级到8.2,不理它。


6.重点来了!我亲自试验,绝对成功的按法:保持ITUNES 打开,保持IPHONE打开,两边都是好好的。按住HOME键(按多久不管,也没必要按很久嘛)1-2秒,然后按下并按住POWER键让IPHONE强制关机,整个过程保持2个键都不放。


7.关机之后,送开,歇口气。按住HOME键不妨,点一下(注意,一下,不是2下,也不要按住不放)POWER键,等显示屏右下角出现发现硬件,并且有DFU字样的时候,就可以送开了。此时ITUNES说要叫你恢复。不理它。


8.按住shift点击“恢复”按钮,选择你下载好了的2.2.1官方固件,恢复吧!如果你的水果白了,那么恭喜,你不会出现错误1600等等莫名其妙的东西了。错误1600折磨了我近2个小时,参照无数帖子仍然不能解决,后来采取按住HOME+POWER进入恢复模式的方法,又会出现错误20(第7很重要)


9.恢复到最后,出现错误1013,然后ITUNES又叫你恢复,继续无视它。


10.同时按住HOME和POWER强制关机,黑了屏幕了就放开2个按键。然后开机,IPHONE上面的画面就不是提示你连接ITUNES了,而是开机正式画面。ITUNES自动打开(或者你自己打开),过一会儿,自动激活就成功了。


11.开始用2.2.5-2越狱软件越狱吧.

一天时间整理完毕.回帖是美德.希望大家能用上.

请问强制关机跟自然关机有区别吗?小弟我按照LZ的操作就第一次进入了DFU但是ITUNSE没有任何提示,之后我再次按照LZ所说操作但是就进不到DFU了```

v0.915044

- fixed EROM UPGRADE feature for db2020 phones.
it will be active when no settings set and RECOVERY pressed.
thx to arash for reporting.

- fixed s1 flash readout in .ssw mode, thx to kokoka for discovering.


rapidshare FULL SETUP LINK

Code:

beta testing period ends on 13.09.2009 23:59 gmt+3.

at the moment we decided to set prices as follows: (prices)

prices for a1/a2 phones will be lowered soon to minumum prices
of corresponding level from our "best friends" pricelist.

perhaps they will raise it to match ours (best for both teams),
perhaps they will make it free again (aerix).

finally, i should mention, that RESET mode is NOT PANACEA.
it WILL NOT fix bad flash ic - which can be reason of initial GDFS corruption.
alas, credits will NOT be returned in that case - take it as is or leave.

credits will also NOT be returned in case of bad communication cables.
that is especially valid for j132 pl2003-based "things".
