MacBook shuts off 2/3 of the way in boot, internal ssd read only?

This MacBook Pro I have is second hand, so I do not know its past. It boots up, takes a little while to show the apple logo, then gets 2/3 of the way on the loading bar then powers off. Booting into the recovery options and going to disk util, I can't edit the drive at all, and I can not erase it, as it says it is read only. I can't reinstall Mojave to it (current version), as when trying to choose the internal ssd it says it is locked. Running first aid just comes up with another permission error. Booting from external drives into ubuntu, windows, and mac os, does not help the case.

At this point, I would normally assume that the internal ssd is broken, yet I can fully read the drive without issue. When booting from an external mac os install, I can actually open apps that are on the internal ssd, like adobe illustrator (I just got to the login page, didn't bother logging in). After trying for a day and a half, I do not know where to go.

I don't fix these often so there could be something I haven't tried yet, I think I have cleared the SMC and the NVRAM, tried safe mode (can't get past init boot so doesn't even get the chance), and tried other software methods (all fail because ssd is read only).

Just to clarify, my macbook has a internal ssd, non-upgradable, with a touchbar.

Sorry for the wait. Here is the info from CoconutBattery:

I will also add that the logic board has no water damage/corrosion.

a battery replacement might help with it not being able to boot fully, either that or a logic board replacement, but try a batt replacement

There is something you could try, but it would be... risky to your data.

Take the drive, save any data you find relevant. Since you know how to boot into linux, boot into linux, open terminal, and run 'sudo fdisk -l'.

Find the NAME of the drive. It is probably something like 'sdb' or 'nvmexxxx'

then, type 'sudo dd if=/dev/zero of=/dev/NAME bs=512 count=100000 status=progress'

This will erase the boot sector of your drive and partition data, and non-securely format the drive. It is possible it *might* allow for a reinstall of the drive on your macbook. But, cant promise

@duckmcquack I tried running that to no avail. It says it wrote to the disk but it hasn't. And that is with the "of=dev/NAME" part of that command being fixed to "of=/dev/NAME". Same issues in disk utils.

Have you tried running a different ssd or HDD in the machine? Because honestly sudo dd really ought to stick to a functional drive. At this point, the major question (is the problem the SSD?) becomes a matter of elimination

@duckmcquack - That’s not an option here as the storage is soldered to the logic board.

If the system is stable enough I would install this gem of an App to check your batteries health and it’s charge CoconutBattery post a snapshot here for us to see.

Sadly, the flash chips that make up your storage encountered a major failure. In most cases there are no more free blocks with a low number of writes. This often happens in smaller drive configs that get a lot of data churn. Hopefully some other event corrupted the storage.

What you need to do to at least salvage your stuff. You need access to a second Mac system which you can connect yours to in Target Disk Mode Transfer files between two Mac computers using target disk mode. Getting your apps and data off.

Once you do that you should be able to leverage the second Mac’s Disk Utility deleting the partitions and reformatting the drive. Then you should be able to do an OS reinstall.

If Disk Utility fails or the OS reinstall fails thats the end of this system logic board. Replacing the Flash chips is a bit of brain surgery! Finding someone with the skills and needed tools is not easy let alone cheap.

I saw somewhere online that you can jerry rig a connector for a small m.2 where the SSD chips are but that is rather hard and I have 0 experience in micro soldering. Everything else works fine so I might just turn it into a little ubuntu/Linux machine with the logic board.

I appreciate your insight on this.

@lucaslowe - This series (TouchBar) has no means to support an M.2 SSD. The Function key model did have a removable SSD and there are a few M.2 adapters as Apples SSD is propriety design.
