This is not something that you will ever normally have to do. Restoring or reinstalling BridgeOS firmware would only be needed in the following situations.
1. Failed macOS Upgrade
2. Failed macOS Combo or Delta Update
3. Failed macOS Security Update
4. Failed macOS Reinstall
5. Failed BridgeOS or Failed Firmware Update
6. “Command Option R” fails to boot your T2 Mac to the newest version of macOS Internet Recovery. (Example: 10.14 is out but the Mac boots to 10.13)
This link shows the different ways you can boot to the Recovery Partition or Internet Recovery support.apple.com/en-us/HT204904
Typical symptoms that you might see that would indicate a failed or bricked update.
Mac Seems dead
Will not turn on
Black Screen
No Fan Noise
Power on LED Light does not turn on (Mac Mini & Mac Pro)
If you find yourself in one of these situations you can follow the instructions below.

After restore, my mac won't shut off. but keeps booting to internet recovery. Alt, CMD R, CMD shift R, Nvram/SMC reset do not work. only thing it will do is boot to select wifi. onece I select wifi, it goes into internet recovery. internet recovery fails with 1003f, 1008f, and I think 2002f. I have done this multiple times. Any ideas is appreciated.
how to do with one broken mac only?
Thank you! Spent 2 days trying to restore a 2019 macbook pro for work and this did it! I've been working with macs for 10+ years and just found out they have DFU mode. Mind blown. The steps I took to wipe and restore this particular Mac I do ALL the time, and just did half a dozen of the same model A2159 and this one was the only one that bricked. Like I said, I spent 2 days on this googling and your video was not top results, it was buried in some forum post. Maybe add 'internet recovery loop' or 'can't restore from USB' will help google find this video?
Hi, can i restore a macbook air 2018 (intel i5 processor) from macbook 2015 with the software?, my macbook air turn on, lights up on the keyboard and sense click on the touchpad, but has black screen; i have another macbook but 2015, this tutorial it serves for my configuration? thx a lot
does this work on a mac mini 2018?
If you put a MacBook into DFU mode then realize you didn’t need to (the MacBook wasn’t bricked, we were trying to downgrade the OS) is there a way to exit the DFU mode? Previously we were able to at least get to the spinning globe but now the Mac is totally dead and we haven’t been able to successfully do the DFU process.
This was very helpful! thank you
How do I do this on a T1 mac? After replacing a relative's 13" 2017 Touch Bar MacBook Pro battery, not only is the soldered internal SSD not working now, but after getting an external one and installing mac OS, it wont let me past the wifi screen saying that it needs a critical software update and fails to do said update. After doing some research, i think that something with the touchbar's firmware is wrong, but I can't find any instructions on how to reset it. I am really disappointed right now because when I booted an Ubuntu live installer, it worked without asking me for any update. Guess my relative will be using linux from now on 😐.
Hola compañero , para bridgeOS 7.4 funciona?
can i do it using as host a 2013 mac? using usb to usbc adapter on that side?
You sound like Harrison Wells from The Flash.
Thank you sooo much 🙏🏻❤.I am a student. I did everything possible, but did not work accept this solution. This worked perfectly for me.
dfu mode isn't working.
Can I do this with my 2 2015 mac book pros? what cable do I need? thx
Hello Mr. Macintosh, I need ipsw for my macbook pro 13 2020 i7. I cant find it
I want to restore with Configurator
I used your instructions to unlock my activation lock but it was showing that it had a update so I when to updates and it started working on Ventura but as it got to the end it resorted back to activation lock can you advise on any other way I could update
Was only able to get through midway of step 4 of 4 and then it showed me the padlock. Tried from DFU screen four times. I wish I never updated my OS because this was my last resort. So bummed I can't even start up my macbook pro now after updating the OS.
hello, I have a 2019 iMac and it has an EFI password, with this procedure you can remove that efi problem?, How could I do this procedure? My macs do not have USB-C, well, the 2019 imac has Thunderbolt 3 but I have a 2012 mac mini
Good heavens, I spent more time than I care to admit trying to follow Apple’s horrible instructions. THANK YOU!!!
I can't get my MacBook OUT of DFU mode lol, I'm assuming that something is fried. It just sits there loading and then I get either error -1 error -21 or error-75
Anyone can help with this ? Can’t find anything on the internet ! https://youtu.be/gOAnfaZg-9w
Thank you!
Same problem( When I start DFU mode, it appears Macbook Pro text below the DFU window. Because of this it gives an error at the end of the reviving
Can you tell how I can change "Macbook Pro" to "Apple controller"
Update 03-04-2023. By disconnecting from the host Mac, I was able to put the problems Mac into recovery. Using the "Restore" option in Configurator, the problem Mac woke up but was unable to restore MacOS. So, I disconnected the two Macs. From there I was able to boot the problems Mac to Recovery Mode. With help from Mr. Macintosh, plus my own persistence, I am recovering this previously $1999 MacBook Pro! Thanks very much for your help!
I was trying to revive a 2020 A2551 MacBook Pro with a 2017 A1708 and was getting nowhere. So I tried using a 2020 M1 MacBook Air to revive the problems Mac. Configurator immediately went into DFU mode (Cool!). So, following Mr. Macintosh's instructions, I was able to start the reviving process and all appeared to be goin well – UNTIL – I got this message "The System cannot be restored on this device. The operation couldn't be completed (AMRestoreErrorDomain error 75 – Failed to handle message type StatusMsg (missing data volume) [AMRestoreErrorDomanin – 0x4B (75)]" Now, believe it or not, this all makes sense – because my client had tried to fix a shutdown-rebooting issue on their own and did the following: "I ran the erase option under System Preferences". I am guessing the client actually went into Disk Utility and erased one of the volumes. Now I am stuck and wondering how to revive this beautiful high-end 2020 13" MacBook Pro with a missing volume. Any suggestions how to cure this? In a couple minutes and going to disconnect the two laptops and see if the problems Mac will boot to an external installer.
Do the MacOS need to be the same for the revive option? What if you’re not sure which is installed on a Mac stuck in DFU?
Hi after doing a restore or revive it keeps booting to internet recovery but it won't let me connect to any WiFi network. It doesn't show any nearby WiFi networks at all.
Охуенно
P.S. If you got error "Apple Controller is not booted" just disconnect cable and restore via Internet Recovery by pressing command+R. No more error -1008f. Thanks for video!
