Hey guys...

first of all, this is my first post here, so i would wish to thanks everyone for all that have been done till now.

Well, i have searched for this info here using the search tool but i havent found it.. i would ask to forgive me if this is an already known info.

Well, i was talking to a guy on our PSP comunity at Orkut, and he works for Sony doing technical assistance for the sony PSP...

so, in the middle of our talk he said that the kit for "unbrick" the PSP is very simple, is just a special batery that makes the PSP go in "DEBUG MODE" and a 256 Mb Memory stick...

Well, i did not have realised how important this was till is aw the other post saying about the memory chip that has a capacity of 256 Mb.

Unfortunelly i do not have enought knowledge of electronics to try it, all that i do was try to change the wires in the connection (like some years ago we used to do on some motorola cell phones). but no success :-(

IF some of you guys, try it and have any news, i would really apreciate.

hugs to you all

Something like this was guessed here, although nobody has yet figured out whether that's actually true.

Yes, thanks for that Jim
there is a way that i can move this post to that thread?

well, so now i am just confirming you that, that circuit seems not to be just a batery status or a recharge circuit... it tells more than that...

but i think that if we do not put our hands in one of those bateries we will never be able to discover that =(

no, it is separated, and it is changed everytime they get a new firmware version (and they must return the old one). he is trying to get with a friend the 1.50 version of the firmware (when he started at sony, it was already the version 2.01).

He is from São Paulo but actualy he is somewhere in japan, and i am From Curitiba, south of Brazil.

Our comunity is at the www.orkut.com (google comunity service) and the comunity name is PSP Brazil.

Always nice to make new friends

hugs to you all

Be very careful that you don't do anything illegal in the process.

Viper, i think that the "ilegal" referes to something that goes against the law. My friend is not on-line often, so probably o next weekend i wil talk with him.

Probably he is scared of something... japan is not his country, and if he do something wrong there, he will be deported back to Brazil.

Well probably he is not the only guy in the world who do it, seems that every oficial Sony technical assistance place have one of those kits. With soooooo many guys around doing it, i do not understand WHY this is so new...
