Ошибка 4042 при прошивке айфона

I experienced exactly the same problem with my iPhone X. I am hoping that a call scheduled today with Apple Support will lead to a solution to this problem. I am very disappointed so far. I suspect that there is a problem with iOS 15.1 which led to this.

Hola Aarón!!! Pudiste solucionar tu problema? A mi me está pasando exactamente lo
mismo con mi iPad de 6ta generación.

I just had the exact same issue with iPad 6th generation with 97% battery charge. The iPad is now completely black screen and does not power on. Apple customer service were not of much help and didn’t really know what the issue is. Although being loyal to apple for many, MANY years now, they have really disappointed me.

Same issue here . Unable to restore from DFU mode in Apple Configurator 2. Have tried multiple cables, PC’s, Macs, blah blah blah.
Following this thread in the event that a true wizard comes up with a viable solution. I do believe it is software related, rather than hardware. My iPad 7 has been «babied» and is in brand new, pristine condition.

Hello, I have the same problem with my Ipad with is little used, impossible to restore or install new software with dfu… I hope apple can fix this problem or they can just change ipad for new ones to customers that have problems with fault 4042.

Same !!
I think new IpadOS 15.5 have bug on Ipad Gen 6

iPad Version: 6th Gen Wifi + Cellular

I had the same error(4042) on iPhone 11. It had the black screen of death. It didn’t do anything. So I left iPhone plugged into my pc, while i went online to research this error code. This forum was the only thing that pop-up. This was an hour ago. Then as I’m reading these issues in this forum, my phone sign out of iTunes and came on and it works just fine. It just seems funny to me after reading these issues I thought my iPhone would never work again. I’m pleased or blessed cause it found a way out. Credit goes to the extra ordinary intelligence. Thanks.

Iphone XR is having a similar issue after 15.6 upgrade
Pls help if there is a solution. thanks!

iPad 6 wifi not turning on after auto update took place to 15.6.1. now it is only detected in dfu mode by iTunes, but every time error 4042 comes while restoring. Same error when restoring to iPadOS 15.7. IT was running perfectly fine till iPadOS 15.4 (before update).

Same issue with an upgrade for an iPad 6th generation — after a system update, iPad becomes visually unresponsive and won’t even force reboot, iPad only shows up in Recovery / DFU mode*, and Recovery mode fails with error 4042. Seems like iPad 6 and similar-age devices have been reported multiple times, so I suspect this error is tied to common chipsets of the time.

To reach Recovery mode, I plugged directly into a Mac (I happened to use a MacBook Pro 2020 with macOS Monterey 12.6), pressed Power+Home for about 10 seconds, then release Power (keeping Home) for about 6 seconds until the iPad showed in Finder or Apple Configurator (or iTunes on older computers).

I had a similar issue happen on an update about a year ago, and it eventually recovered. While DFU failed on multiple attempts, I also continued to keep it plugged in for several days, and at one point it simply booted up on its own. So maybe it’s just REALLY sluggish to finalize certain iPadOS updates.

The following article may be related, not just because the referenced error numbers are close, but because the behavior is similar:

Logs for error 4042 on iPad 6 wifi. This is the second time an auto-update has gone wrong. (Earlier a similar update strangely disappeared all my iCloud files into thin air).

Tried multiple times with different cables, Windows and MacBook(M2) computers, in different apps like iTunes, Apple configurator and Finder, still same error.

PS — Tried with iPadOS 15.6.1 and 15.7 as they are the only signed versions available. Will try restoring with iPadOS 16 also when it comes out.

I had the same problem. Screen was black until i plugged it into a charger from an outlet, then logo kept going on and off. Tried all teh fixes to reset and restore through itunes, but nothing worked. I found a little info on what could cause problems with an iphone rebooting and took a guess that it was the battery. Had the battery replaced and it’s fixed. I checked a few forums and also called some cell phone repair shops, was told: it’s the phone gone bad, it’s the circuit board, it’s the software. I took it to the repair shop and told the guy it I thought it was the battery. He said is was a chip, but would humor me and replace the battery to prove it wasn’t the battery. Turns out, it was. It cost me $25 to get the battery replaced on an iphone 6S, but prices can vary greatly depending on the repair shop, so I’d do some calling to find out what it costs to replace a battery on your device before you decide on which shop to visit.

Did anyone ever find a fix for this. I have the same thing on a 6th Gen iPad which died during an OTA update from iPadOS 16 to iPadOS 16.1

Black screen and only detected in DFU mode but error 4042 whenever a restore is attempted.

I found a solution for me.
For me the problem was caused by a corroded contact of the haptic engine.
The phone kept stuck in bootlop because of a broken hardware.
After unplugging the haptic engine my phone instantly booted again.

So just unplug every hardware component one by one.
E.g. unplug the haptic engine, check if phone boots, if not, plug in the haptic engine again and try another hardware part.
repeat the procedure until your phone boots.

Maybe to speed this up, just unplug every hardware component and check them and their contact points if they are broken or something is unusual, maybe you can see something at first sight.
