My promise pegasus 2 R4 Firmware refresh failed and cannot be turned on now. How do I get it to write the right firmware? Rework.
All the indicators on the front panel are not bright.
The power button cannot work.
Only the power part small fan can turn.
There is a blue light on the internal motherboard.
I removed the main board from a normal working Pegasus 2 4R and replaced the failed device with the firmware. After the replacement, it worked normally.
Make a preliminary judgment on the failure on the motherboard. It should be the failure of the refresh firmware to affect the normal operation of the chip.
