Alright I'm planning to get a Japanese PSP cause I want the silver one. I barely know anything about firmware stuff so I'm a complete noob. Some questions..can someone help me out.

1. How many different regions of firmware exist? e.g Japanese/US/UK
2. What's the difference between each countries firmware?
3. Which countries FW is the standard FW people refer to when talking about it?
3. If the PSP I buy comes with firmware 3.11 does this mean it's a Japanese FW?
4. If I want to upgrade the 3.11 FW to 3.50 FW, will it only work if I upgrade to the Japanese 3.50 FW? Or can I use any?
5. If not, what happens if you try upgrading to a different 3.50 FW?
6. Is it possible to brick your PSP from upgrading (that was unsuccessful) or only from downgrading?

On ebay a seller is also selling a silver PSP with 1.5 firmware.

7.Would this most likely be the Japanese 1.5 FW?
8.If it is, can I upgrade it to 3.40-OE? Would this be the US OE or the Japanese OE? Or is there only the US one?
9. I imagine the seller downgraded the PSP to 1.5 since you can't buy them as 1.5 now right....so does that mean it can't be upgraded to official firmware like 3.50?

Sorry for all the questions. This stuff is really confusing. Thanks

1. so far all FWs (update EBOOT.PBP files) have been identical (even though the sony websites say you must use the right region!!!)
2. n/a
3. n/a
4. n/a
5. n/a
6. it is possible to brick upgrading or downgrading as you are writing to the flash. just don't touch the power cord or battery and you will be fine

7. n/a
8. n/a
9. there is a small chance it was a ta82 or 86 mobo which means one of the id keys needed to be patched to dg to 1.5. this can cause problems upgrading to official sony FW BUT can be fixed with some neat utilities (keycleaner etc.). BUT why would you ever want to go to official FW, you can install custom firmware right from 1.5FW. (google 3.52 M33 CFW)

It doesn't really matter. Some people say the US update wouldn't work, and had to use the Jap 3.50. It downgraded just the same.

#1: 2.81 -> 3.03 -> 3.11 DoH (no more :D)
#2: 1.00 -> 1.5 -> 3.03oe-c
#3: Ceramic white 1.5 -> 3.03oe-c -> 3.40oe
Whatever happens, happens...

you don't seem to understand, there is no such thing as US FW, they are all IDENTICAL (at the moment anyway).

you will be fine.
