iPhone update error 100 06a6 0064

Hey everyone,

I really need help with this because my iPhone 13 Pro Max has basically locked me out and I’m trying to avoid losing all my data.

What happened:

My iPhone was running iOS 18 and was almost out of storage (2-3gb left).

I tried updating to iOS 26 through my Mac because the phone didn’t have enough space to update itself.

The update failed and now the device is stuck in Recovery Mode (the laptop + cable screen). I made my last backup 11 Months ago and the data in-between are incredibly important to me. I just wanted to give a quick update and never expected it to give me such a headache...

What I’ve tried:

Tried “Update” through Finder multiple times → always fails with Error 100
Tried different USB ports and different Macs → same error
Didn’t press “Restore” (I can’t lose the data)
Didn’t enter DFU (screen always shows standard Recovery logo)

Went to an Apple Store → they didn’t even connect the device, just said “restore it”

iPhone 13 Pro Max, iOS 18

You [the OP] obviously didn't read or didn't understand my aeroplane analogy. You chose not to buy a parachute here.

A mechanical failure of the plane would not come back at you, but the consequences of hitting the ground at 120mph would.

In this case, it appears that the OP had a parachute at hand. The same computer that the OP used to try to install iOS 26 could have been used to back up the iPhone before attempting the update.

However, a parachute doesn't do you any good if you leave it on the ground when you go flying …

Again, this comment does not offer any technical solution and will not advance Apple's technology. Parachute or no parachute, the plane is defective. According to your logic, there would only be good pilots with their parachutes, but who would still fly old planes? But that's okay, because we have parachutes. 😥

Sorry to be the bearer of bad news, but anything that wasn't already backed up or synced to the cloud is gone. There is no way to recover it at this point.

Is there no fix in development or solution in the pipeline? I can wait, my data is really important.

I would also like to understand the problem in detail and whether it is a hardware or software issue.

A plane you are flying may malfunction, but it is your choice to carry a parachute or not.

Yes, this is the classic Apple ecosystem.

I agree if the product is flawless, but in this case there are still a few shortcomings.
