Description

This is an official firmware update that was released on the Network Update servers in early 2005. Sony did this to make sure that a full system software update can be received and installed on the PSP hardware before the US launch.

Due to the design of the network update feature, they did not use update test servers and used the production servers. This allowed people to go into the 'Network Update', download and install the software causing a soft-brick.

At the time, this was considered a brick due to the symptoms causing the hardware to no longer boot. There were several theories to why it happened such as the bootloader (IPL) being deleted due to missing a IPL driver in the updater. What actually happened was that the registry/user settings were not downgraded from the Release 1.00 (1.0.3) and the older system software (1.0.0) was not compatible.

In order to properly install it, you will need to install the system software, and then clear out the registry after booting. You can also utilize the registry patcher application to patch the 1.0.3 registry to have it downgrade to the older settings version.
