可惜要有 2.5gb ram才能跑
小弟的pc太老舊,沒法跑
請有興趣的大大試一下看看



TinyCFW is a simple tool I put together for a friend of mine. He has an iPad2 GSM and has his 4.3.3 SHSH but since Apple is no longer signing 4.3.3, it isn't possible to downgrade to 4.3.3 without getting stuck in a 1015 recovery loop.
What TinyCFW is:

• It will modify an existing ipsw for an ipad2 gsm/cdma or iphone4 gsm/cdma
• It WILL modify the ipsw TO UPDATE YOUR BASEBAND TO THE LATEST!
• It will create an ipsw that you can use with TinyUmbrella AND iTunes to restore to a version of iOS that you have SHSHs for.
• It is primarily for iPad2 with a baseband OR iPhone 4.

What TinyCFW is NOT:

• A jailbreak
• An unlock
• A tool to protect your baseband.
• A tool that will restore your device to any firmware
• A tool for use with iPhone 3GS, iPhone 3G, iPad, or iPhone 4S

The usage is simple. Start the application (double click on the jar or run the .exe file). You must have java and at least 2.5gb ram. (Yes I know. It's a lot. Get over it. I didn't write this to be massively distributed. I wrote this for a friend and am now just sharing it with everyone). Once the window comes up, click the top button and choose an ipsw for which you have SHSHs for. The app will scan it and tell you the firmware and baseband versions in the ipsw you selected and the firmware and baseband versions that will be in the target ipsw when you click the second button. If you're ready, click 'Save Target IPSW'. This will take a minute or two and when it is finished, you will have a file named:




<your original ipsw name>.bbupdate.ipsw.


You can use this ipsw with iTunes and TinyUmbrella to restore your iPad2 GSM/CDMA back to say 4.3.3 (if you have 4.3.3 SHSH).


This is a VERY initial release. I never intended on it being a massively supported tool. It's just something I used in passing. If it helps you great! This functionality will exist in far more robust form when I finally ever release TinyPwn.

可惜我ipad2來不及存到4.3.3shsh
看看那天iFaith能支援ipad2
我就能升級了

我的部落格有寫上教學及tinycwf自制韌體下載的載點了
個人是覺得能順利的把有 4.3.3shsh ipad2 降回去才是最大的重點**"
本人試過~確實是可以用的
前提是要有備份到 4.3.3的shsh才能使用！

點我看教學

這東西其實沒什麼用...你有 iPhone 4的話用Pwnagetool做一個自製韌體也是一樣的。

恩

我以為有突破性的進展
可以用這個來搭配來回復 iOS5.x 了呢...

原來是讓你不用再用fixrecovery來修正無限recoxery loop省事...Orz

看樣子我倒是認為乾脆再等 iOS5.1 出來再釋放全jb工具來得有價值(如過消息是真的話...噗)

ya! 真的成功了！ 試了三次 才成功！ 第一次 試新下載的韌體 出現錯誤1030 第二次出現錯誤9
第三次 又先將他回到5.0.1 在將之前4.3.5 回到4.3.3的那個韌體 找出來 做成 tinycfw 的回復韌體 用小雨傘 回復就成功了
