How to Upgrade Firmware PSP ke 5.50 Prometheus 2

Display System Information with Prometheus-2 CFW 5:50
Many games released recently can not be played even when using a custom firmware (CFW) 5.50 GEN-D3. To overcome this problem, a programmer from China, liquidzigong develop a variant of the new CFW with the name "Prometheus". Well, recently he released an update to CFW, which he called Prometheus-2 CFW 5:50. He claimed that with this CFW, we can play games that previously could only be played with official firmware (OFW), 6:30. Wow! How do I uninstall?
Basically, CFW-2 5:50 Prometheus has all the features of CFW 5.50 GEN-D3, coupled with the compatibility for games that require OFW 6:30.
Before starting the upgrade process, it should be noted that the firmware upgrade process is at risk of damaging your PSP and I am not responsible if your PSP is broken (Brick) or experience a loss of data and various types of anomalies / other damage. So make sure you backup your PSP data and prepare you mentally before upgrading this CFW.
Here are the requirements to upgrade the firmware:

    * You are not a PSP amateur / beginner - Upgrade the firmware is at risk of damaging your PSP!
