restore psp battery

Stuxnet

hi,
i think I've inadvertently made my normal battery into a Pandora battery by accident !! :eek:
i was messing around trying to downgrade when i did it, now when i boot my psp with original battery its asking do i want to install 3.80 m33 or standard 3.80,
i already have a Pandora i bought before, so how can i restore my original battery to its factory condition so i can boot up normally, if i can thanks

i have no backup of original as Ive formatted the stick since....doh:pac:

psp 1000


EDIT i took out the battery and tried to boot with just the AC I'm still getting 3.80 cfw/standard options, so maybe its not the battery after all, so please advise,
have i bricked it ?
i did try and boot with pandora, it goes through the "flashing" pages, but when i restart after it, i get same screen again

Tachyon = 0x00300000, Baryon=0x00040600
pommel = 0x00000104, Syscon DK =0x3FFF
Nand size = 33554432
Model   : PSP standard (TA-81)

Press X to install 3.80 M33
Press O to install original 3.80
Press [] to dump nand
Preaa L+R_start+home to restore nand dump phisically (dangerous)

never mind sorted, got it into recovery mode and was able access the memo card from there, stuck in new boot files and it worked straight away !
happy days again
