- **A supported device in any iOS version (listed above)**
- The IPSW firmware for the version you want to downgrade to
- Links: [iOS 10.3.3](https://ipsw.me/10.3.3), [iOS 8.4.1](https://ipsw.me/8.4.1), [iOS 6.1.3](https://ipsw.me/6.1.3) (ignore the signing statuses in the site)
- **32-bit devices** - The device needs to be put in kDFU/pwnDFU mode as part of the process. There are a few options:
- Normal method - **jailbreak is required**. Users must install [OpenSSH](https://cydia.saurik.com/package/openssh/). Users in iOS 10 (A6/A6X) must also install Dropbear from my [Cydia repo](https://lukezgd.github.io/repo/)
- DFU method - for alternatives, the DFU advanced menu can also be used. See "Other notes" for more details
- **A7 devices** - jailbreak is not required. The script will assist in helping the user put the device to pwnDFU mode
<ul><li>For 32-bit users using Pangu and normal method, install the latest untether for your iOS version <ahref="https://github.com/LukeZGD/iOS-OTA-Downgrader-Keys/releases/tag/untether">here</a></li></ul>
- **If something in the process does not work for you:** try unplugging/replugging the device, switching between different USB ports/cables, also try USB 2.0 ports
- **IPSW file integrity** will be verified before restoring and/or creating custom IPSW (if custom IPSW is already created, this will be skipped)
- **For users having issues with missing libraries/tools:** Re-install dependencies with `./restore.sh Install`
- To devices with baseband, this script will restore your device with the latest baseband (except when jailbreak is enabled, and on iPhone5,1 as there are reported issues)
- This script can work on virtual machines, but I will not provide support for them
- If you want to use other manually saved blobs for 6.1.3/8.4.1, create a folder named `saved`, then within it create another folder named `shsh`. You can then put your blob inside that folder.
- The naming of the blob should be: `(ECID in Decimal)_(ProductType)_(Version)-(BuildVer).shsh(2)`
- Example with path: `saved/shsh/123456789012_iPad2,1_8.4.1-12H321.shsh`
- Select the "kDFU mode" option if your device is already in kDFU mode beforehand. Example of this is using kDFUApp by tihmstar; kDFUApp can also be installed from my repo
- For A6/A6X devices, "DFU mode (A6)" option can be used. This will use ipwndfu (or iPwnder32 for Mac) to put your device in pwnDFU mode, send pwned iBSS, and proceed with the downgrade/restore
- For A5/A5X devices, "pwnDFU mode (A5)" option can be used, BUT ONLY IF the device is put in pwnDFU mode beforehand, with an Arduino and USB Host Shield (checkm8-a5)
- If you cannot find Cydia in your home screen, try accessing Cydia through Safari with `cydia://` and install "Jailbreak App Icons Fix" package from my Cydia repo
- **For users with A5 Rev A ([8942](https://www.theiphonewiki.com/wiki/S5L8942)) and A5X ([8945](https://www.theiphonewiki.com/wiki/S5L8945)) devices:**
- **A5 Rev A devices:** iPad2,4, iPad mini 1, iPod touch 5
- The jailbreak option **might not work** on A5 Rev A devices. (see issue [#70](https://github.com/LukeZGD/iOS-OTA-Downgrader/issues/70)) The script will warn you if you enable the jailbreak option on one of these devices
- For users that downgraded **without** jailbreak option, and have manually jailbroken with the EtasonJB app, it is recommended to install "EtasonJB Disable Bootloop Protection" from my Cydia repo
- For users that downgraded **with** the jailbreak option, and to users that have installed "EtasonJB Disable Bootloop Protection", your device might take a very long time to boot, possibly 20 minutes or more
