I'm pretty sure, yes. if you can, the best thing to do imo is to install infinity (if possible), then quadruple boot with lme, pro, ark, and ofw. ofw can be booted by holding down home when powering on. I do not know if it's a part of infinity or any cfw though. that's how I had mine. I always updated ark on ark or on ofw. ark now has a way to update itself from system update, so it's perfect. I sold my psp a few months ago, so I don't know if anything has changed, but it's very easy. if something corrupts, boot ofw with the home button and use chronoswitch to install full ofw. the psp stuff has gotten so easy that it should only take you a few moments to get back on cfw.
