Windows Version of iPad 1 Gestures and Display Mirroring (Wired) Without Jailbreak

[d.B.]

This is the Windows version of the modified redsn0w package I posted in the following thread:
iPad 1 Gestures and Display Mirroring Without Jailbreak

It is nearly identical to the OS X version except for a change in the version of redsn0w used. If there are any problems specific to the Windows version of this redsn0w modification please post them in this thread.

Here is the code I have written to perform this operation once again:

/*

    }
    // Child process
    else if ( result == 0 ) {

        exit(-1);
    }

Hi d.B.

Thank you so much for your effort firstly!

My ipad1 is running 4.3.5 and hesitate to upgrade, since i've heard that if using redsn0w to enable gesture in ios5, will cause safari and ibook not working, is it the same with your modification?

[d.B.]

While I will provide no guarantees the tool will work, this version of redsn0w is modified to enable gestures and display mirroring only. It will not perform the standard jailbreak procedure. So, safari and all other application should work without issue, without requiring a tethered boot.

[chg1226]

This is the Windows version of the modified redsn0w ...

Hi d.B., this is great!! i tried this on my iPad1, it workds fine without having any problem!!
Just wondering, does it apply to iPhone 3GS with iOS5?

[qwerty7788]

Great job，it works on my ipad1！！！

[ipad1]

Db tnx for this one! Works fine!

[sealym]

Thank thank very

非常感谢你温柔的努力~

[Chekz0414]

Will it also work on iPod touch? :0 I really want the gestures

[1a9413dqk2]

Thank you very much, i love having the gestures on my ipad 1. I did run into a problem, wifi syncing, home sharing and itunes remote no longer work for me. has anyone else encountered this problem?

[bcutter]

Hi there,

I have a few questions before running your tweak(s).

1) Will the tweaks still be available after the next iOS-Update (for example 5.0.1)?
2) Is a reboot of the iPad possible? Or are the tweaks as the jailbreak "tethered"?
3) In case I restore the device, I guess the tweaks will be gone and I need to do them again right?

The code itself looks like it really doesn´t do anything else in the system.

Would appreciate your answers!

[japao666]

super, please modify patch for iphone 4 for enable video mirror. Iphone identify n90ap

[Pyrofallout]

super, please modify patch for iphone 4 for enable video mirror. Iphone identify n90ap

I too would love to see AirPlay mirroring enabled sans jailbreak on the iPhone 4!

[1a9413dqk2]

Thank you very much, i love having the gestures on my ipad 1. I did run into a problem, wifi syncing, home sharing and itunes remote no longer work for me. has anyone else encountered this problem?

Never mind, I restored the original software and then tried the gestures tweek again and everything works now. Thanks again!

[mirol]

It doesn't work for iphone（ios4.3x）.Can you modify it for iphone（ios4.3x）,please?

[catz122]

I used the mod and it seems to have added gesturing to the iPad 1, but not mirroring. Also, I am now having trouble setting the ipad 1 up for wifi sync. Any help would be greatly appreciated.

Correction. The wifi sync works fine. I am still wondering about how to enable mirroring. Thanks for any help you can offer.

[sailingjazz]

Is there an updated version of this program that will work with the latest iOS build? I get a message that the .ipsw is not supported.

Thanks

[bestman50]

Will this work with 5.0.1. Got voice-control working and it broke multitasking gestures on my iPad 1?

Thx bestman50

[IrrelevantD]

d.B. thanks for getting this to us. It really saved me some headaches after updating to 5.0.1 as I frequently used the display mirroring at the time.

Any chance you can make an modified version of redsn0w 0.9.10b6 to work with iOS 5.1?

[No_Smoking]

Hi there
I currently have iOS 5.1.1 on my iPad (1st gen) and stumbled upon this modded redsn0w. It does exactly what I need (mirroring!) I noticed its a bit out dated, and didnt want to do something to potentially brick my iPad. My question is, will it work with my iOS?

Hopefully d.B. is still around? =)
