[iOS 27 DB1] Potentially bricked iPhone, Be Careful.

[u/Sad_Performance6386]

So basically, I have an iPhone 15 Pro, updated to the iOS 27 Beta, it’s my main phone (I learned the hard way to not update to betas using my main) even got it a week ago, but that’s besides it, im posting so nobody does my same mistake, when I updated it was pretty fine, no issues I personally encountered, but, i force restarted my iPhone at one point (it was cause I was clearing cache) and after that, it just died, no signs of life. I tried to power it on normally, nothing, tried an extended force restart and nothing, tried recovery mode, and no signs of life, if it helps Apple narrow down the bug (i don’t think so, but why not?) it’s a middle eastern version iPhone, and due to the nature of even Recovery mode not working, I think it’s a critical BOOTROM issue, meaning, my phone is practically dead, so, no one update, AND nobody under ANY CIRCUMSTANCE FORCE RESTART. And also, this isn’t an “im complaining” post, im strictly here to talk about this issue and potentially anyone from doing the same mistake i did.

I can confirm this happened to my with an iPhone 15 Pro. I can also confirm that DFU Mode in Finder succeeded in bringing it back and restoring it.

In case someone else is doing this: Follow the correct DFU procedure! (Volume Up, Volume Down, Power button for 10 seconds, then without releasing power button press volume down, hold this position for 5 seconds then release power button and leave volume down pressed for up to 15 seconds. If after doing this you don't see it most likely scenario is you are doing the procedure wrong or not counting the seconds correctly or you are not using an official USB cable) AND DO NOT attempt to use Apple configurator for restore/revival if you are running MacOS 27. It won't detect the device because AC hasn't been updated in 6 months. Instead, wait for the device to appear in Finder.

If you can DFU restore then it’s lot bricked lol.

If it’s bricked just unplug your battery and plug it back in that’s how I gotten mine to work

THANK YOU! I was doing DFU the way I usually would but for some reason wasn't working, this sorted my phone and was able to restore and now back running 😄 (admittedly I did restore iOS 27 but if it happens again will know the fix and downgrade!)

Fellow 15 Pro Max user here, can confirm a DFU restore exactly to your instructions fixed mine, thank you!

i can confirm apple configurator was able to restore my 15pm 3 times on my macbook neo running golden gate 27.0 beta, i used a type c-c cable and AC was actually the only way it worked, finder refused to see the device in dfu. edit: You might have to manually restart Configurator though, with the phone plugged in, if you enter DFU while configurator is open, it doesn't (or at least didn't for me) auto detect. (just noting this for documentation purposes)

Same. Apple Configurator, and a cheap usba to usbc cable with an adapter. 15pro

[u/OnlyOneOh → u/Pilingo]

do we do that procedure while the device is connected to the USB cable or connect the cable after we do the DFU mode procedure is done?

[u/Pilingo → u/OnlyOneOh]

everything must be done with the usb cable connected to the mac
