1. Are your memory card show "Magic Gate: Supported" in properties menu "Information" of memory stick?. If there another phrase - it mean that your card is illegal.

2. I try to make nand dump of same FW at five times, and ALL five nand dumps are different each other. So, are you tryed to make other nand dump and test it?

Mm, very interesting.

1. If you try to 1.50 downgrade and make nand dump this 1.50 state?
2. Up to OFW exemply and make it's nand dump?
3. Install 3.52M33 from 1.50 and make it nand dump?

If 1-3 - will be bad-blocked i think, it's hard-ware problem, or bug in Pandora Recovery Menu.

You have a bad block on the flash/nand....install an ofw like 2.0 on it once 1.5 is installed...2.0 will remap the bad blocks so they cannot be written to.

Having bad blocks is normal.

Thanks Erland
one question
Now i'm on CF 3.52-4 M33 motherbord is TA079/81, which is better way to do what you said ?
1 . return on 1.5 with recovery,
2. upgrade OFW 2.0
3. downgrade with pandora
4. Install CF 3.52

Or for downgrade 1.5 i must use always Pandora ?
I'afraid to broke motherboard keys, now psp work good
Thanks

I made what you said me.
I followed this steps:
1. downgrade from 3.52-4 to 1.5 with pandora
2. Install OFW 2.71
3. Backup nand flash
4. Downgrade from OFW 2.71 to 1.5 with Pandora
5. Install CF 3.52 M33

Anyhow after i did all these steps i get the same error "page 1152 bad block 36"
Where i make a mistakes ?
Perhaps i must istall OFW 3.50/3.52 for remap bad blocks ?
Please help me.
Thank

few days ago done this: recover perma bricked psp (3.51m33 ta082/6) with pandora, went to 1.50 then installed 3.52m33 and update 4 after that. Then custom ipl and fixed/unpatched all keys + key5 then i made a nand dump and there was no bad blocks. today i flashed 3.52m33-4 over 3.71ta079. the nand was taken from ta082 , so make nand dump from ta082/86. that i read is the most nand backups with bad blocks r made from ta079/81. u should try. btw mine mobo is ta081 but i didnt tried to make a nand from my fw.
sorry for my bad english, i do my best :)
