A2141 Question mark

[Djsp]

I have this MacBook that has a question mark at startup as if there was no operating system I enter the recovery but if I start the installation freezes and restarts if I try to enter the disk utility it crashes and restarts at the question mark, where should I start?

Try DFU restore first.

I tried to restore the dfu, it completes the operation without displaying errors but entering the recovery and trying to install the system it restarts and returns to the question mark

Did you try starting in safe mode?

Also test the SSD in target disk mode.

 

[Djsp]

In target mode it is not detected I don't think there is an operating system installed

 

[2informaticos]

No need to have macOS installed.
SSD must be detected in target disk mode on another Mac attached.

The MacBook is detected in target disk mode, I assume that the ssd must be good otherwise they wouldn't even show it to me, the only thing is that I can't do the installation in recovery because it crashes and restarts, the recovery in dfu mode stops without showing errors, honestly I don't know what else to invent

I had the same problem with an A1989 and it turned out to be a faulty touchbar - if your touchbar isn't working then i'd try and unplug it then see if it'll let you load the OS. If your successful a replacement touchbar will be required.

In my case I solved it with a new battery, but the defect, I'm sure concerns the mosfets of the CPU, it seems the same defect of an A1398.
