• i think my BOOT ROM version is old. As of Sept 2021 the Boot Rom version for macbook pro 14 1 (mine) the version should be 499.40.2.0.0. Mine is 205.0.0.0.0

I am pretty sure that would be the issue. I need updating it to something in between or something earlier than that and gradually tr updating it to something greater. but how?

edit: the original apple ssd is in the laptop again. i did above efi check in this ssd.

edit 2: i found a small utility called SilenKnight 2 and got the below picture

Thanks HWTech for the reply.

Yes I have a NON-Touchbar model. I heard the same about failing ssds on these models too. Luckily it's removable in my one if i ever need to remove.

Yes I erased the drive using both ERASE MAC and manual formatting several times (disk format rather than the partition format) each. No need to worry about backups. Last night I started from scratch again. Installed 10.13 High Sierra and wanted to observe what it will do if it formatted into old HSF+ rather than APFS and do the updates of high sierra only. Same problem occurred. Laptop remained on a black screen with responding touchpad but no activity even if i keep it like that for nearly 2 hours on its own. At least holding and releasing SHIFT OPTION COMMAND POWER for few seconds for few times brings the laptop back to life. That's big relief.

One very tiny and probably not important information that i did not include with my previous post that the laptop was originally liquid damaged. :)

Battery was dead and the keyboard buttons were sticky. So replaced the entire keyboard and battery with another one. the replacement keyboard came with an original used battery with 196 cycles on it. The keyboard looked original too. Backlight works even now.

i appeared to have an external hard drive with original macbook air ssd. installed MOJAVE on it as it has the quickest installation time among all OS X versions. booted from that drive and downloaded the updates. restarted to see the same black screen with clicking touchpad. 

I also borrowed a replacement non-original drive from another identical laptop. Installed Mojave. downloaded updates. Restarts. Same result.

no error found with apple diagnostics with ADP000 code. DriveDX shows the disk is OK (see the report and screenshot attachment below). I don’t know how useful this data would be to you Since I used a different internal ssd now.

Tried all again without the battery connected. Same.

Laptop works fine apart from that update issue.

i also included the screenshots for my current system

Started to think it may be failing to update the SMC and BOOT ROM version to something latest. Is there a way that I can try updates released just after my versions of boot rom and smc? Maybe the downloaded version of firmware is far greater than this laptop can handle. sometimes with windows laptops you need to update bios that way to get the latest installed. So I think updating the SMC and BOOT ROM one version at a time may make some difference. Do you have any idea if there is a place to download OLD firmware updates?

I am afraid I am about to install Opencore Ventura as it is modified skip firmware updates a.f.a.i.k. so the future updates would not end up in black screen.
