Hello!

I don't speak very well english, sorry...

I have a psp 1.52 recovered in a bad state which I repaired. when I succeeded in making it walk, I have desired to upgrader into 2.0 for then to downgrader into 1.5! but for to make the update, the system request to connect the AC input...

it is there that I realized that the jack alim (where connects the charger) did not function: ( and that does not come from the charger considering when I connect it on my 2.5, it is put in load! I buyed it (the jack) and installed but it doesn't work!

I am sure to have welded it well and one cannot be mistaken in direction (I work in electronic wiring) I verify the tensions and looked at if a component had not died and all appears good to me!

then I ask désespérement: having to you it a way of being able downgrader without it?

so not, ... I will have had the first psp 1.52 undowngradable:)
PS: the psp was already open before I thus have it impossible to make walk the guarantee!!!

Thank you for advance @ +

Does the AC charge the battery?

I mean, the jack doesn't work at all or does the psp not know it's being charged?

Unless you have a warranty on your 2.5, you could swap the boards to downgrade it and then put it back?

I hope it's something simple and you get it working the way it should.

No, the battery does not take care and the psp knows that it is not connected to the charger!

you want that I exchange the motherboards? :S

in this case there I exchange also the firmwares...

thank you for your answer

Try using a different batery. I am not sure how much control the Smart Batteries have on the system, but I have seen other devices do strange things when the Smart Battery is faulty, or a non-genuine battery is used.

Otherwise, take another look at the jack and related circuit with a magnifying glass to make sure it is all ok in case you missed something.

Good Luck,

The left fuse is for the Charger :D

You can buy a new fuse, or just short it out, works fine too :P
