silverspring's blog said:"There’s some confusion with regards to the relationship between the firmware version and the motherboard. There isn’t a one-to-one correlation between the motherboard version and the firmware version. That is, if you have a TA-088v2 board then you have (at least) a 3.90 firmware. However the inverse is not true, that is, it doesn’t necessarily mean that if you have a 3.90 firmware then you have a TA-088v2 board (you may have a TA-088v1 board or maybe a TA-085v2 board).
It’s just the TA-088v2 boards first started appearing with 3.90 firmware. But you may also still have TA-088v1 boards or TA-085v2 boards being produced with 3.90 firmware too. Especially depending on the region. The firmware versions listed above are the earliest firmwares seen with these boards. These boards were released in Asia first so the firmware version may be earlier than on US or Europe models.
Basically, you cannot tell what board you have just based on the firmware version (though you can make an educated guess), however if you have a certain board then you will know at least the earliest firmware it will have."
"The new TA-088v3 boards only come in 4.xx and above. The new pre-IPL in these boards can only boot the 4.xx IPL’s, it cannot boot older IPL’s from 3.xx. So as long as the PSP doesn't come with 4.xx fw you know it won’t be a v3 board. Just remember, v3 boards cannot run firmwares under 4.xx." Source
