(adsbygoogle = window.adsbygoogle || []).push({}); I have a 3.55 and was wondering if it is worth it to update to 4.xx cfw
Does it have ftp/filemanager and REACTPSN? And can I backup any game?

umm im not too sure,im just going to keep my 3.55. my opinion tho

Its better to keep your 3.55... You never know!!

Do not update if you wish to play cracked psn games as there are tons of it on 3.55 but none of them work on higher cfw. Also as lvl 0 is exploited expect a new cfw each and every time sony updates their ofw. 3.55 cfw is the best and stable use it till you get max out of it!!
