3utools Downgrad Ios Ipad 2

The lowest version you can go with an iPad 2 and without SHSH blobs is iOS 6.1.3. This is because Apple still signs OTA (over-the-air) iOS firmware for this version. You can use OdysseusOTA to downgrade to this version, but only if you're jailbroken. If you're not, then you can't.

You're allowed to downgrade your iDevice from higher iOS version to lower iOS version only when Apple is still signing the old firmware. To downgrade your iDevice, the following stuff are necessary. For instance, a computer, the latest version of 3uTools or iTunes and a stable network.

First of all, you need to download and install the latest 3uTools on your computer. When it's done, connect your iPhone to a computer using the USB cable.

Note: The downgrading process is the same for every Apple iDevice. Ensure you have backed up your iPhoneif you don't like to lose iDevice's data.

From 3uTools, you can easily know the iOS version of your iDevice, 3uTools will automatically show you the matching firmware for your iDevice also (only available firmware for your iDevice will be displayed in 3uTools Easy Flash).

Then you need to select one firmware you want to downgrade and click “Flash”. You’re not suggested to choose the checkbox that “Retain User’s Data While Flashing” while downgrading.

Keep waiting till the flash process is finished, it takes 10 minutes generally. Then iDevice has been successfully downgraded.

Except knowing the matching firmware form 3uTools Easy Flash, you’re able to check the available firmware for your iDevice in 3uTools Firmware. As shown below, the green dot means that this firmware can be used to flash or jailbreak, while the white dot means this firmware is not available for your iDevice, you can’t use it to flash or jailbreak.

I collect old computers, and so my friends often find interesting things for my collection. My friend Paul recently gave me an old iPad 2 for my museum.

The thing is, it didn’t feel very old. I still use an iPad 3 every day as my main tablet (it still works fabulously well, apart from the bloat on modern web pages, that sometimes tend to cause Safari to grind to a halt). The donated iPad 2 ran iOS 9.3.5 (very slowly), which is basically what my iPad 3 runs (iOS 9.3.6 due to last year’s GPS bug that Apple patched).

So to be a candidate for my museum I really wanted to revert it to its original state, which would have been iOS 4. But Apple don’t allow downgrades, and all installs of iOS have to be cryptographically signed by Apple.

So I set about seeing if jailbreaking the iPad would help. Apparently not – jailbreaking on its own doesn’t bypass the iOS signing.

But I found a few references to iOS 6.1.3. It seems this was the first version of iOS to allow OTA (Over The Air) updates to iOS. So Apple allowed 6.1.3 to be manually installed via USB (so that devices running earlier versions could update, and then update to the latest version over the air).

So I tried a few versions of this – first using a Windows tool (3utools) – which failed with an obscure error, and then using iTunes on a Mac (having downloaded iPad2,1_6.1.3_10B329_Restore.ipsw from https://ipsw.me/iPad2,1) – which revealed that Apple wouldn’t sign it any longer. That corrupted the device so I was forced to reinstall 9.3.5 using iTunes.

Doing a bit more reading, it seemed Apple had stopped signing 6.1.3 a few months ago, possibly due to a security bug in iCloud on iOS 6 that they wanted to avoid being exploited? Details were a bit vague.

Then I found some references to them still signing OTA updates to 6.1.3, just not manual updates via IPSW files. The tool Vieux promised to be able to downgrade to iOS 6.1.3 or 8.4.1. Again the description is vague, but I think it’s installing the update from the IPSW file, but persuading Apple that it’s an OTA install to fool them into signing it? I’m not exactly sure – there is never much deep technical documentation on these hacking tools – the authors seem to think everyone just wants tools that are easy to use, so don’t often explain how they work!

Vieux looked promising, but for 32bit systems like my iPad 2, it required ssh access, which requires a jailbreak!

So next, find a jailbreak for iOS 9.3.5. It seems there is only one that works: Phoenix. It’s an app that you ‘side load’ onto your device, and after each boot, you manually run it to activate the jailbreak. Any app loaded has to be signed by Apple, and there were various webpages promising versions of Phoenix already signed, but Apple revokes the certificate as soon as they find them, so they don’t last long.

The alternative is various tools that you can use to sign the app yourself. Anyone can sign their own app for development purposes, but the certificate only lasts 7 days. Or if you have a developer account (as I do), you get a year until you have to re-sign and re-install it.

Reading forums, it seemed many tools that previously did this (3utools, Cydia Impactor) no longer worked.

I did try a tool called iOS App Signer, which should have signed an app using my developer certificate for a full year of use, but I couldn’t get the signed app to install on the iPad, whatever certificate or settings I used. I gave up on that (but see below for a possible reason).

Then I found a couple of tools AltServer and AltDeploy. They seem similar. AltDeploy just signs an app with a 7 day certificate based on an iTunes account and installs it to your device. AltServer does the same, but then runs a server on your computer so your jailbroken device connects to your computer via wifi, and requests a new version before the 7 days run out.

Both of them install a rather dodgy plugin. It might make sense, but the developers don’t explain why. It’s a plugin to the Mail app on your Mac, which they say has to be installed, and Mail running, for the app signing to work (they say it’s something to do with requesting your iTunes credentials). A bit more explanation wouldn’t go amiss. I eventually allowed it access (since I don’t use Apple’s Mail app for my email anyway, so there’s nothing useful to hack there).

I then used AltDeploy to sign the Phoenix app. This also failed, but this time I got an error that I could search for (a bad app display name). It seems the Phoenix app uses extended characters in the app name (to join the o and e characters together). The app signing didn’t like that. Perhaps that’s also why iOS App Signer didn’t work? I didn’t go back to check.

Anyway, this issue suggested changing the Phoenix5.ipa filename to .zip, expanding it, opening the Payload folder, showing the package contents, editing Info.plist, changing the Bundle Display Name to remove the dodgy character, saving, re-zipping the Payload folder, and renaming back to .ipa. Then the signing worked, and I had the Phoenix jailbreak app on my iPad!

I followed the instructions to activate it, then kickstart it, then opening Cydia and installing ssh.

Next get the dependencies for Vieux:

I could then plug in the iPad via USB and downgrade:

(When prompted you have only 10 seconds to unplug the USB lead and reconnect it!)

After I did that, I had a factory-reset device running iOS 6.1.3. It seems to be stock iOS, signed by Apple with no jailbreak (although I believe there are iOS 6 jailbreaks that could be installed). But I want it nice and clean, for my museum :-)

Check out that retro skeuomorphic design! It’s not quite the original iOS 4, but visually it’s almost the same, as the flat design didn’t come in till iOS 7.

And now it truly is a museum piece :-D
