Hi! Today Apple released a revision of 17.4.1, now, 21E237. I tried on my SE 2020 and all worked, try now!

A friend in a different state had the same issue (OTA 14.7 update that bricked) with an iPhone 12 (not mini). The Apple Store was able to restore. The tech said there had been a few like his.

correction: OTA 17.4 update that bricked. store that fixer it was an Apple Store in WA.

hi everyone, I had the same problem today while I was updating my iPhone 12 via Mac.

At the apple store, they clearly said that it may be because there is a hardware problem that the previous firmware didn't detect so the new 17.4 automatically sends the phone into lockdown (recovery mode). They asked me 400+ € for the fixing but it seems absurd that I have to pay for something they caused without giving me the slightest chance to downgrade to the previous software.

Same issue, same experience with an OTA update to 17.4 on an iPhone 12 mini. Apple Store genius

• Tried DFU multiple times
• inspected Lightening port, cleaned it
• Confirmed no liquid
• Tried multiple cables
• Tried different Macs
• Tried Apple Configurator 2.
• 

Amazing. My previously bricked iPad is back in action too. I just used the Finder to restore, it downloaded 17.4.1 (21E237) and the restore worked! Luckily I had a backup that wasn't too ancient, that is restored and everything seems back to normal.

Could you boys send me the log of the restore? I wanna compare with mine.

On mine, I receive some errors that swear a baseband fault. But here comes the surprise.

First, I tried to update to 17.4 at my work, same error, 06A6.FFFF (baseband fault), well, at my home i flashed 17.3 and then all worked perfectly (baseband too), but when I insisted on 17.4 via DFU mode and then I got stucked at 17.4 with a broken phone.

As I said, software fault.

Here's the tail of a restore attempt. "failed to install splat" looks like a smoking gun. Something has run out of space which is odd given it is a restore.

Yes! On a iPhone SE 2020. Worked perfectly on iOS 17.3 until I tried to update to iOS 17.4 and i received a error via OTA, then i tried on iTunes, 06A6.FFFF. The iOS 17.4 won't ever be installed wherever I try.

Where I got ****** myself? When I tried to update via DFU Mode. I received the same error, but now even on iOS 17.3, 06A6.FFFF. In other words? Full bricked phone.

Same here. iPad Air 4 worked perfectly until I tried to update to iPadOS 17.4 via a brand new MacBook Pro. At the very end of the update process it threw an error and would not start. Now attempting to restore it goes through the whole process, verifies the software and at the very end:

The iPad “iPad” could not be restored. An unknown error occurred (-1). 06A6.FFFF

The local Apple Authorized Repairer says it is hosed and I need to buy a new one. I'm pretty mad, I feel strongly that the OS update caused this and it isn't a hardware fault.

Hello everyone, I'm in the same situation since 3 days ago. My device is an iphone 11 Pro Max; it was working perfectly fine on iOS 17.3.1.

I tried to update to iOS 17.4 on MacBook Pro M3 Pro with MacOS Sonoma 14.4 and it was exactly the same. After several attempts with 3 different cables (between USB-A and USB-C) and 2 different MacBook Pro's; I still get the same error.

It is inexplicable and unacceptable that Apple stands idly by when it is an error of this version of iOS 17.4 software.

I hope they solve this situation as soon as possible because in my case, I'm losing a lot of time and money. We can't even downgrade to the previous version and even with the beta version of iOS 17.4 I can't solve it.

My iphone is totally locked in DFU mode.

continued: Attempted restore with new 17.4.1. This did not work. Hung. Same error.

The 17.4 OTA update worked OK on my iPhone 12 mini, another family member's 12 mini, and another's 12.

As the Apple Store did, I've tried different cables trying to restore the bricked 12 mini with 17.4.1. No luck

Got this error while updating an iPad Air 5th gen to iOS 17.4.

iPad Air 5 was working perfectly fine and then I saw there was an update, so went to initiate it... it seemed good and then just fails right at the end with the error

Definitely seems like a software issue, I have no reason to believe that there is any hardware issue with my iPad Air 5th gen.
