Yesterday i decide to go back to CEX from DEX but i stuck on some 3.55.
i downgrade from 4.20dex to cfw dex rogero v2 with downgrade 3.55FW
but multiman dont flash bios, it give me error:
Error accessing flash device
please install 3.55CEX/DEX firmware

when i uninstall and install multiman again it gives me error:
cannot access or create default backup folder
game backup functions my not work properly.
Please use different payload if necessary

and when i look in multiman system information it show me firmware 3.55 dex,
but before it show me firmware 3.55(hermes-8)-this in bracket is example
i try install again 4.2 and downgrade again and try install R-3.55-DEX-DG-C_F_W-PeekPoke but nothing help

Here is a guide on how to go back to CEX.

The only thing I can think you may be doing wrong is: either you don't have multiman ver 04.04.03 or newer. Or your not using your original NOR dump flash_stor_35500 and rename it to my-original-cex.EID0.NORBIN

How did you solve it?

The reason it did not work when you flashed your CEX bin, is because you made that backup with software, right?
The backup you use with e3 flasher has to be byte reversed. Did you fix it by byte reversing your backup with flowrebuilder.

I use my first backup made with E3 from 4.11FW when i first downgrade my ps, i use flash fun, and when process finish i patch it with e3(1,2,3,4,5 down, 6up)then restart and install rogero.
yes this backups are made with software. i didn`t care for this because devwiki say that are differences in size from soft and flasher backups, but my are same.

you say that this backup made with memdump i need byte revrsed with flow and then flash with E3? must write this somewhere for future if i stuck again

[haz367]

yes u must for e3 to use them
and ur right about being identical(soft/hard) atleast for NOR, doesn't matter, they just work the same..

to flash the software dump back with E3 first use Flowrebuilder and "Bytereverse it" so the "bkpps3.bin" reads as FI.I and not IFI
