Rolled back to 3.8.0 and everything still works, phew I thought I need a new enisy because the eeprom is toast, turns out the eeprom is fine, still can't upgrade to 3.9.0 though

I'm assuming then that rolling back from a failed 'upgrade' is considered reliable and robust, correct?

I'm always cautious of upgrades such as this, having had a few on various devices over the years that resulted in very tedious corrections.

I guess I'll stay on 3.8.1 for the foreseeable future. There no new feature that I desperately need from the new firmware anyway, plus the quality is great on 3.8.1.

You should still be able to use 3.9.0 (albeit only in English), the part that is failing is writing the language data into the SPI flash.

As long as the first writing/verifying cycle passes, the main firmware has been correctly loaded.

I already tried using it but the printer just stuck at Prusa Research Splash screen, will try flashing it again, in the middle of a 26hr print RN

I tried the firmware on my university's MK3S and it works fine, I think my MB are to be blame

RE: Printer broken after firmware update

Did you try to reset it with "X" after the splash screen hang, or was that how it came up from the flash? It could be hanging in the EEPROM write stage, so a reset or power cycle after the flash should bring it up normally.

How old is your MK3? Any chance it has an older Einsy with the add-on board for the SPI flash memory?

I already hit X but it it still stuck on Prusa Research Screen

My MK3S was upgraded from a MK3, and the MK3 was one of the earier unit.

If I need a new firmware feature,  I'll just have to snatch another einsy from the prusa store
