iPhone 11PM Bricked Overnight While Running iOS 18 Beta

I'm sorry to hear that. I hope you had a backup.

Does it show any signs of life at all?

It sounds like the phone might be low on battery, since nothing works. Just checking, did you try to plug it in for a while (for example 1-3 hours) and try again?

I can't enter recovery mode, DFU mode, reset, charge, nothing.

Keep in mind when the device is in DFU mode, nothing will be displayed on the screen. You'll need to connect it to a computer, and timing is important.

You might want to check out the instructions here for recovery mode or contact Apple Support.

For recovery mode, at the last step, keep holding the power button until you see the recovery mode screen.

For DFU mode (which isn't documented in the link above), timing is really important, so it can take a few tries to get it right.

I've been charging it for the whole day with different cables, bricks, and outlets. I'm gonna leave it overnight just to be sure.

If you charged it for more than an hour already, it should be more than enough.

Nope, no signs of life at all.

Maybe there could be a hardware issue as well, for example either a power or a screen issue. When you're following these steps, you should see the Apple logo on the screen at certain points - and if you don't, it's either a hardware issue or an important part of the boot process being broken (iBoot). If it's the latter, DFU mode should still work.

Here are some detailed explanations for that, if you're interested. I'll use some technical terms here - we're on the DevForums after all 😁.

iBoot is the stage 2 bootloader that loads iOS / Recovery Mode on your iPhone. It can be changed and upgraded. I believe the Apple logo is shown during this stage.

BootROM is the stage 1 bootloader that loads iBoot or DFU.

I think DFU can't break during updates, since it's essentially Boot ROM code waiting to be recovered via USB. So if you really cannot enter it at all, it's a clue that it could be a hardware issue.

does any one have the solution ?

Hello and thank you for your reply.

I just ran into the same issue on my iPad Pro 12.9-inch (4th generation) Wi-Fi trying to update to ios 18.3.1 beta

Unfortunately, I have gone through the volume up, down, and power button about 100 times, and it went into recovery mode ONCE, and that's it (and that too at the Apple Store, but in 'recovery mode', it couldn't be detected by any of their MacBooks—an I/O issue? Then, it timed out).

Every other time (including when Apple technicians try it), it turns the screen off and then, three seconds later, returns to being stuck.

I don't mind wiping it completely clean and giving it a full factory reset, but I can't! (And neither can Apple's Genius Bar technicians.) Instead, I've just been quoted £650 to buy a replacement iPad (which, by the way, £650 for a 4th-gen 2019 iPad Pro??).

I've let the battery drain a few times, and there's no luck when I recharge it. It also does not show up when I plug it into my MacBook anywhere in Finder.

Argh!
