which firmware version you need?
i need version 4.73, tnx if u give me a restorable firmware.

Ever thought off restoring the original nand ?
i programmed a stm32 mcu to do this , first i dump / flash / dump another nor flash and compared result and do this repeatly with other data to insure working good.

next i dump and programmed a lower version file and not worked when i reflashed orginal dump only led breathing and no other function.

Firmware version 3.0.0 expects 3 fuses to be burnt, but firmware version 3.0.1 expects 4 fuses to be burnt. When you install firmware 3.0.1 on the Switch, the console will make sure it burns enough fuses to reach a total of 4. If you try later on to downgrade to 3.0.0, the console will expect to have 3 burnt fuses or less. Realizing there are already 4 of them, the console will enter system panic and refuse to do anything.

i know this is for the switch but same thing happens on the ps4
