Cannot boot from SD card after flashing SPI

[Pelochus]

So recently I flashed Orange Pi OS to SD card, booted from there, updated system, firmware and flashed bootloader to SPI flash. I already had an external HDD with Armbian flashed, and tried to boot from there, but no luck. Afterwards, I tried to boot Armbian from SD card, but I can't boot any system that is not Orange Pi OS (and especifically, it needs to be from SD card, can't also boot from USB even in OPi OS). Tried with different SD cards and USB devices, no luck

 

I believe I need to erase SPI flash in order to boot from SD again, but, how can I do it?

 

Used latest OrangePi OS and Armbian Jammy CLI from 23/01 (stable release)

I would guess too that you need to erase SPI.

For me this video was very helpful 

 
It also covers how to erase SPI flash and initialize it again. 

Or you can read the orange pi 5 manual https://drive.google.com/drive/folders/1Bre2q0bGgXQuQlYaYDMvwstpvtHLmcgX  it covered also the MaskROM recovery steps in case you cant boot from any media anymore.
