MK4 after update Firmware 5.1.2 (Bootloader 2.3.4) Printer is not starting

I installed the new Firmware 5.1.2 today (Released 15.12.2023).

But now the Bootloader is hanging, it seems he has 100%, but after 5 Minutes the Display didn't change the picture.

I start the Printer for 6 times new, but it doesn't work

The booting finished, if the USB-Stick is in, without USB-Stick, it doesn't finish.

Anyone the same issue?

I'm facing the same problem here; I attempted multiple times, but it still didn't resolve.

As a result, I decided to revert to the previous version.

The solution with the USB-Stick, is not a really solution, the same issue after 3 starts. Igo back to the old firmware

RE:

try to reinstall the FW? Otherwise, install the older FW. Put the older FW on the USB stick. After pushing reset, push once the Knob. This must force installing the older FW.

I can reinstall the older version without any problem. However, the issue lies in the inability to install the newer version.

Are there alternative methods available aside from using a USB stick?

Is it possible to utilize the USB-C port for the update process?

Is this common enough for me to avoid 5.1.2?

I was able to upgrade my MK4 from 5.1.0 to 5.1.2 without any problems.

I had the same problem and found this GitHub issue on the upgrade problem: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/3629

I have downgraded to version 5.1.0 and the boot now works again - the bootloader is kept at the new version 2.3.4.

Have a look at my models on Printables.com 😉

It was me who reported that on GitHub.

still didn’t find a solution. I reverted back to the previous version.

I guess I’ll wait for next update.

Same problem here: Got the printer with FW 5.0.1 -> updated to 5.1.2 without any problems. After a restart, it gets stuck in the start screen.

Downgrading to 5.1.0 fixed the problem, but a bad solution...

I have the same problem as the person who opened the thread. So I have also reverted to 5.1.0. Today I tried the new version 5.1.3, but again the MK4 won't finish booting. Now I'm back to 5.1.0 again...

I had the same problem when I set up my printer. I uploaded FW 5.1.0 so I could get the printer up and running. I have now been able to upgrade my firmware to 5.1.3 via Prusa connect.

 

Hope this helps others with the same problem

I didn't use Prusa Connect. What does Prusa mean to solve the issue?

But when Prusa Connect the only option to solve the problem is, then i must create a account only for updating...not realy a fine solution.

My MK4, delivered last week, has firmware 5.1.3 And this bootloader problem which hangs during launch also appeared (2 or 3 times)

Once, the reset was not enough (new blockage), the machine had to be turned off and restarted.
