(adsbygoogle = window.adsbygoogle || []).push({}); I used to do dual boot between :
1/ OFW 4.25
2/ CFW 3.55 rogero 3.7

to swap between the 2 firmware, i used the "slow" dual boot, and had to flash my NAND using the dump on the microSD.
to go to 4.25, it was a simple dump of 4.25 firmware
to go to 3.55, it was a patched dump of 3.55 CFW firmware

I now want to do dual boot between
1/ CFW 4.30
2/ OFW 4.25 that i want to update to 4.31.

how can i do this ?
If i use NOR patcher on 4.30 CFW nor dump, would dual boot work ? or should i stick to my3.55 dump, which means that to go back to 4.30 CFW, i would have to go throug a long process (using previous patched dump -> rogero 3.55 -> QA Flag -> 3.55 OFW -> 4.30 CFW, which means that my CFW HDD would need to be formated each time...

thx for help
