How to Downgrade iOS 14 to iOS 13! (Without Losing Data)
How to downgrade iOS to older version
If you have decided to go back to the previous iOS, you can easily do it. But remember there’s the biggest risk is of losing your iPhone/ iPad data as the process completely wipes iPhone data.
Backing up iPhone to iCloud or iTunes after upgrading to the latest iOS doesn’t help as this backup file won’t work once you have downgraded to the older iOS. Hence, you should have a backup before the new iOS was installed to be able to restore iPhone after downgrading. Else you lose all data.
Secure methods to downgrade iOS:
Note: Ensure the following before you downgrade iOS:
How to put your iPhone or iPad into recovery mode
Theres no button tap to revert your device back to the standard version of iOS. So, to get started, youll need to put your iPhone, iPad, or iPod touch into Recovery Mode.
- On iPhone and iPad devices with Face ID, Press and hold the Side button and either volume button until Slide to Power Off appears, and then drag your finger across the slider.
- On iPhone 8 and iPhone 8 Plus, hold down the Side button until Slide to Power Off appears, and then drag your finger across the slider.
- On iPhone 7, and older, all iPads with a Home button, and all iPod touch models, press and hold either the Side or Top button until Slide to Power Off appears, and then drag your finger across the slider.
- On iPhone iPad devices with Face ID, press and hold the Side button until you see the Recovery Mode icon.
- On iPhone 8 and iPhone 8 Plus, press and hold the Side button until you see the Recovery Mode icon.
- On iPhone 7, iPhone 7 Plus, and iPod touch (7th Gen), press and hold the Volume Down button until you see the Recovery Mode icon.
- On an iPhone 6s and older, all iPads with a Home button, and iPod touch (6th Gen) and older: Press and hold the Home button until you see the Recovery Mode icon.
If for some reason, Recovery Mode doesnt trigger to let you downgrade your iPhone from a beta or public release, you can also try putting your iPhone or iPad into DFU mode. Device Firmware Update mode is a little trickier to get into, but will often force a restore even when nothing else works.

Downgrading or upgrading to a no longer current version of iOS is generally not possible once Apple stops signing the old software, as is needed when iTunes is preparing to install or restore an iOS. This signing window typically is closed within days of a new version shipping.
Putting a newer iOS on older hardware that never even supported that OS is near impossible.
As part of the iOS restore process, iTunes has to check with Apples servers to sign each install of iOS just like App Store apps must be signed to run. Once a new version comes out, Apple stops signing previous releases to keep everyone running the same iOS version and to prevent you from jailbraking your device again after restoring by forcing you to do an update.
If you had previously Jailbroken your device on iOS 6, it may be possible, providing you have saved your SHSH blobs which can sign the install instead of Apple. See this article for some general information around this topic.
This wikipedia page contains a list of iOS devices & the latest iOS they can support – https://en.wikipedia.org/wiki/List_of_iOS_devices
Note: There is a new method of downgrading/upgrading that doesnt require Apple to be currently signing, and it works on newer devices that arent present in the first list of my answer below. The tool for it is called futurerestore (codenamed Prometheus). The biggest caveat to this tool is that you must be jailbroken in most cases before initiating the restore (and you only have one shot, so a failed restore will force you to install a signed firmware) (if that signed firmware is also jailbreakable, then technically you get second chances, but its rare for that to be the case unless theres a bootrom exploit for your device). Right now, the best tutorial for Prometheus is by @iPodHacks142 and is endorsed by the author of Prometheus, @tihmstar. I will be updating this answer later to explain more about it, but I wanted to get this information posted here sooner rather than later.
Other Note: I am missing information about the original Odysseus which allows a few 32-bit iOS devices to downgrade in the iOS 6 and 7 range.
Other Other Note: There is an even newer method of downgrading/upgrading that will allow almost all 32-bit devices (doesnt include the 32-bit devices that can install iOS 10) to go from iOS 9.3.5 firmware to any other iOS 9.X firmware.
Other Other Other Note: There is an new bootrom exploit for A5 to A11 devices called checkm8. It can allow you to install any IPSW as long as valid SHSH blobs are provided (it is unclear if you need a valid APTicket as well, as its been demonstrated it isnt necessary in some cases).
When I find some time, I will add these to the answer below. My answer is still up-to-date (other than anything having to do with these notes).
In short, unless you have one of the following devices (devices with A4 processors or earlier, hereafter referred to as “pre-A5 devices”), you cannot install anything except for the iOS versions that Apple currently signs:
The following subset of devices do not utilize SHSH blobs, and can therefore install any version of iOS at-will:
It is important to note that while all devices listed in the first section do have working bootrom exploits, there are different types of bootrom exploits, and each allow for different levels of boot manipulation.
The following devices can utilize a special bootrom exploit that allows for installing any version of iOS without SHSH blobs:
The following devices have a different bootrom exploit known as limera1n, which allows installation of any version of iOS as long as valid SHSH blobs are provided:
Installing iOS on any device using a bootrom exploit requires you to put your device into a state known as Pwned DFU, which allows you to install custom firmware. Youll also need:
If you do happen to fall into the small group of users that have all of these pieces, consider yourself lucky, as you can use iFaith by iH8sn0w to stitch your SHSH blobs into the firmware to create a custom IPSW that you can use with iTunes after you put your device into Pwned DFU using iREB inside iFaith.
Not all instances of the iPhone 3GS are the same. Models manufactured in early 2010 or earlier (old bootrom) have a bootrom exploit that allows for downgrading without SHSH blobs, while newer models (new bootrom) have a separate exploit that allows for downgrading with SHSH blobs.
It is in fact possible to install iOS versions that Apple isnt singing anymore on devices newer than pre-A5 devices in very specific circumstances. The two devices that qualify are the iPhone 4S and the iPad (2nd generation). Using redsn0w, the iPad (2nd generation) can be downgraded to iOS 5 from any newer version, and the iPhone 4S can move from any version of iOS 5.x to any other version of iOS 5.x. Both of these operations require multiple specific sets of valid SHSH blobs and APTickets.
For all devices which contain an SEP chip (Secure Enclave Processor) (i.e. iPhone 5s and beyond), an exploit will be necessary against the chip itself in addition to a bootrom exploit, or else the SEP chip will reject the firmware. You can, however, construct an
.ipsw that contains an older version of the SEP firmware so long as that older version is being signed or you have an exploit that allows you to replay the old signature. If the older version is not supported on the version of iOS that youre installing, Touch ID and other SEP-dependent features will be disabled.
For pre-A5 devices, it is usually possible to extract valid SHSH blobs and APTickets for the current firmware regardless of that firmwares signing status. iFaith was developed to perform this operation. A situation in which this may not be possible would be if you arrived on your current firmware via an OTA (over the air) update.
iH8sn0w has some unreleased downgrade exploits for devices that do not contain an SEP chip.
You have to download the wanted IPSW file. Open iTunes and shift+click on “restore” Go to your file you downloaded and click on it. iTunes will do the rest. If you had the beta of iOS 7 you may be able to go back to iOS 6.1.3/4. If you have iOS 6 SHSH blobs you may also be able to get back iOS 6. But if you dont, you have to download iOS 7.0.
