Getting Back to iOS 9.3.5 on an iPad Mini
The truth is, this isn't as simple as it sounds in 2025. Apple stopped signing iOS 9.3.5 years ago, which means the standard restore path through Finder or iTunes is dead. You can't just plug in your iPad Mini, select the IPSW file, and go. The server side just rejects it. But there are ways around this, and I've done it on several devices over the years. The method I use relies on a tool called checkm8-based recovery. It exploits a hardware-level vulnerability in the boot ROM of A5 through A11 chips, which covers the iPad Mini 1 through Mini 4. Once you get into DFU mode, you can essentially bypass Apple's signing requirements because the exploit runs at a level below the normal verification process. Here's what the process actually looks like on a real machine:
First, you grab the iOS 9.3.5 IPSW from a reputable archive. IPSWDB.com is one place that still keeps old firmware files. Don't trust random download links from forums. The file is around 1.2 gigabytes for the iPad Mini 2, 1.8GB for the Mini 3. Save it locally. Next, you need a Mac or Linux machine. Windows support for this is spotty at best, and I've seen more failures on Windows than I care to count. Install the latest version of checkra1n or the iOSOpenDev tools. You'll also need libimobiledevice and ideviceinstaller from Homebrew or your package manager. Put the iPad into DFU mode. This is the part where people mess up. Hold the power button and home button together for exactly 10 seconds, then release the power button but keep holding home for another 5 to 10 seconds. The screen stays black the whole time. If you see the Apple logo, you held it too long. Start over.
Connect the device with a genuine Apple cable. Third-party cables cause more issues with this specific process than any other factor I've seen. Run the exploit, enter recovery mode, and then use a tool like palera1n or checkm8's follow-on scripts to load the IPSW. The restore takes between 20 and 45 minutes depending on your machine's I/O speed and how much data is already on the device. I ran into a problem last year with an iPad Mini 2 that would loop during the restore every single time. The device would get about 60% through and then throw a -1 error. After about three hours of troubleshooting, I found that the root cause was the device having a corrupted baseband radio calibration partition. The workaround was to restore the baseband first using a separate tool before attempting the full IPSW install. Once I cleared that out, the downgrade went through in about 22 minutes flat. A few things you should know before you start:
Get the Full Details
iCloud Data and settings won't carry over cleanly if you do a downgrade. You're essentially starting from scratch unless you have a backup from the iOS 9 era, which most people don't. Apps from the App Store that require iOS 10 or later will not work. You'll be limited to whatever apps were available and compatible with iOS 9.3.5 at the time. That's a pretty restrictive set in 2025. Safari on iOS 9.3.5 doesn't support modern TLS versions, which means a lot of websites simply won't load. This is one of those details people overlook. If your goal is browsing the web, this isn't going to work well. If your goal is running a legacy app or game that requires an older iOS version, then this is exactly the right path. Another thing nobody mentions: the restore will wipe your device. There's no in-place downgrade. If you don't have a backup from when you were still on iOS 9, you're losing everything. Plan accordingly.
The iPad Mini 1, 2, and 3 are all viable targets. The iPad Mini 4 technically can do it too, but the checkm8 exploit chain is less mature on A8 chips and I've seen about a 30% failure rate in practice. If you have a Mini 4 and really need this, expect to try it a couple times. There are paid tools on the market that claim to make this easier. Most of them just wrap the same open-source tools I described above with a graphical interface. I wouldn't pay more than $10 for any of them, and honestly, most aren't worth even that. The free tools do the same thing. If your iPad Mini is newer than the fourth generation, this entire guide doesn't apply. Apple hasn't released a checkm8-based jailbreak for A12 and later chips, so you can't bypass the signing requirements on those devices. Your only real option there is waiting for a future exploit that may or may not ever come out.
The whole process, once you know what you're doing, takes about 40 minutes from start to finish. Allow an hour if this is your first time. The biggest failure point is the DFU mode entry. Get that wrong and you spend twenty minutes starting over. Everything else is pretty much automatic once you're in. If you just want a working iPad and don't have a specific reason to run iOS 9.3.5, consider whether this is actually worth the effort. The device will feel noticeably slower, many apps won't work, and you'll be dealing with security vulnerabilities that have been public for years. But if you need it for a specific app or game that refuses to run on newer iOS versions, this is the way to do it.
