Flashing eeprom...

[ab_geee_eee]

Hello, after backing up my battery's eeprom and downgrading a slim and trying to flash my back-ip eeprom i get a message saying: Error at writing address 0x14 :( does this mean my battery will not be able to be converted back to a normal battery?:confused:

[cal360]

No I have that problem. Sometimes it means you have to flash it twice to restore it to normal. I'm not sure why it does it, it may be because you had a bad backup and it can't restore it all, it's the same address as mine so don't worry too much.

Ok, ive flashed it three times now but it still doesnt work :(

[cal360]

Try turning off your PSP completely and turning it on again a few times and eventually it should work again.

[ab_geee_eee]

ok, ive now tried it 6 times and it does not work :( I have a different back-up of an eeprom for this battery, i saved it on my brother's pc, should i try flashing that eeprom?

[cal360]

Try it, make sure it's from your battery though.

[ab_geee_eee]

okej, im sure its from my battery but i guess i have to wait until tomorrow because my brother is busy now and it's on his pc :(

[cal360]

I would try my process again then just for luck :D, until you can get on his computer.

[ab_geee_eee]

hehe yea ill do that

[cal360]

Actually i've got something else you can try. Once you have flashed the battery, turn off the PSP then take out the battery and then put it back in and hopefully on the second time of doing this it should work.

[ab_geee_eee]

I did that just now and it still does not work I think it's because the eeprom.bin was a bad back-up :(

[cal360]

Ahh oh well I tried :D.

[ab_geee_eee]

Hehe yeah, but thank you anyway :) ;)

[ab_geee_eee]

Ok, I tried the other eeprom.bin and I still get the same message.. :( Is the file supposed to be 4kb? I can still open my PSP using that battery normally anyway so I don't really mind..

Thats why it wont write if your battery boots up your psp normally then its a normal battery and you cant write a backed up eprom to a normal battery only a pandora one

[cal360]

hodgy47 is right. All I was helping you do is boot your PSP normally with your battery not fix it. Mine does exactly the same thing and as long as it boots there's nothing to worry about. Mine works perfectly without any faults.

[ab_geee_eee]

Ahha ok, thank you ;)

Are you using the L+R flash? Don't!! Use square, and it will write the generic serial 0x12345678.

Are you using the L+R flash? Don't!! Use square, and it will write the generic serial 0x12345678.

Don't use the square flash as it writes a code that simulates the original, but isn't. It's there as a last resort and can cause various problems with the battery that can cause it to play up for example by not charging to its full capacity. Use the L + R sequence as it restores the original file to the system and will cause no problems.

[ab_geee_eee]

ahha ok, cool didn't know that :)

[Dr Eggman]

I tryed, but i got the same error as ab_geee_eee, and if i put the battery it would kick into service mode! But, the program told me the serial was mine (0x69****A), But it would still kick into service mode. When i wrote the generic serial, i got no problems at ALL. And my PSP charges full!


Oh, and if i PM you my serial, is there anyway i can somehow Re-write it? when i formatted my memory stick i forgot to backup the eeprom.bin and i would prefer to use my original (just in case sony says i tampered with the battery if i sometime send it in for service)

[hodgy47]

You cant generate a matching eprom serial for your battery so if you deleted the backup its gone and as far as i am aware you cant use an eprom from another battery if the default generated one works dont worry as for sony finding out if you do need to put your psp in for service just buy a cheap battery or borrow one for while its away.
