apple configurator padlock

[luckydip]

Guys,

Been away from repairs for a few years, good to see many familiar names still around!

Working on my first T2, short on PPVIN_G3H_P3V3G3HRTC_R, which is now sorted. Machine starts to recovery, don't have appleid/password so tried to reinstall Mac os just boots back into spinning globe/recovery.

Tried to connect apple configurator, gets into DFU, starts process but after a few minutes shows padlock for both revive and restore. Tried different macs, usb cables still get the padlock. Any ideas?

Once it shows padlock after DFU restore it means the restore was successful.

Connect a direct line Ethernet cable if WiFi is weird.

ok thanks for the padlock clarification.

Just got my new usbc/ethernet cable and tested on another macbook - works fine. When I connect to problem macbook there is no connection - just stays on the select wifi screen. Not sure if ethernet is unavailable in recovery?

If I connect to wifi, it loads to select language screen, then have the option to activate with email/password which I don't have. At this stage the cable seems active as the lights are flashing on router.

the only option I have is to erase mac, I select this, get the circle and the macboook reboots to recovery again. Seems like the erase/activation is not happening?

Another thing I've noticed is that none of the keyboard boot commands are working like option to select boot, pram reset etc. I've tried another keyboard to rule that out.

So there is a activation lock on it, pram reset doesnt work on never models like T2 M1.

I think its a T2 intel, option to select boot should work,or has that gone as well?

Is there any reliable place to check icloud status like Apple used to do with serial/IMEI?

cheers

Newer machines don't use CMD + R, but now need to hold power button down to get to an options menu for recovery etc.

T2 default security disables boot from USB. You can't change this unless you know the admin password. So you are forced to connect to the internet to reinstall, and of course the activation lock is on Apple's side so you can't go further. You need to bypass the lock or get it removed.

Apple put a massive dint in the 2nd hand market because of these features. Most dead machines I buy for parts where I fix the boards are activation locked.

Thanks for this, once the original owner removed it, os installed fine.

Any tips on where I can check icloud status online?

Re: apple configurator padlock

Hi. Have a 2019 A2141 16" macbook with a damaged screen (customer damage) that is boot looping with a chime.

Ran, for my first time, the DFU process using the client's 2nd new macbook and this 'dark' unit was found and we were able to setup into DFU mode.

Ran REVIVE (as we need the client's data!!) and the remote computer ran a few steps (4 in all) and then the target computer rebooted.

Now the remote computer is showing a padlock and the target is back to the boot loop with the chime.

Any ideas on how to proceed? Client owns the computer so he will have passwords but should the boot loop with chime have halted with the DFU process? Or we facing another fault?

He needs his data off this A2141. Apple was of course useless to assist @ Somerset Mall (Michigan).

Re: apple configurator padlock

Suspecting the issue with this A2141 is a power cycling fault. The fan spins -> unit chimes -> few seconds later, fan turns OFF and the cycle repeats. Current draw peaks to around 2.7A before dropping to 0 and recycling.

I hate to be the bearer of bad news but a restore is the only option at this point. Had a similar issue with a A2141 to recover data. It would not revive properly, informed the customer he was ok with restoring it and the computer worked again. I would honestly download a previous patch and dropping it in AC2 and hit revive. If that fails it's gotta be restored

Yes only site to check iCloud is imei.org that’s the site I use to check serials before taking in trade ins or purchasing boards that need repair. They charge like I think .05 cents to check. I don’t know how they do it but it works.
