2/i have a cobra dongle,if i will use the dev_flash dev_blind method and swap it with 3.55 cobra the way you told me before could i use my cobra key with mcmm manager to load ps2 games ?
note:cobra requires 3.55 cobra firmware, but after i swapped dev_flash file with ofw 3.55 the first time, system software was on 3.55 not on 3.56 like before this operation,so could this make cobra soft work ?
I'm glad it worked. You should be able to get out of Factory Service Mode no problem, while you can't downgrade you can still get in and out of Factory Service Mode on 3.56 JFW.
1/There is no way to know how JFW will react with future CFW. Who knows what the future will hold.
2/No that won't work. The Cobra CFW uses special lv1 and Lv2 patches which allow the dongle to provide it's features. Swaping a dev_flash from the cobra cfw won't let you use the cobra dongle. As the lv1 and lv2 are not in the dev_flash.
EDIT: I'm in the mood for creating/modding things, if you don't like the XMB layout of JFW. I don't mind making a mod of it to make it more like Rebug or regular CFW or with the XMBM+ or anything(within reason).
