I will be crystal clear with this, since if you don't know or you don't want to know it's up to you. But be advised once you read this i get as you fully understood what i needed to say about 4.11/4.20 CFW.
1) 4.20 CFW NOT EXIST
I will give you (to you, yes you who are reading this) and not even lift your sight to see on your top right a banner:
The banner speaks for itself and you can even click it to get tutorials.
A) Highest Hackable firmware = 3.55 / Means that the only Hackable firmware until today still 3.55, not other.
B) Firmware downgradable = Yes. 4.2x / This means that if you use a Hardware flasher you can even downgrade from 4.20 (Like E3 flasher or progskeet) but you have to open your console no softmod downgrade.
C) CFW PSN Access = No PSN / Well this means that if you are in CFW (custom firmware) you cannot enter PSN.
If we PS3HAX have the information about some CFW 4.20 a real one, will be updated on that banner that you don't saw in first place.
Now you have the CEX>DEX conversion method.
Tips for the ones who are starting in the board/forum:
1) Never trust youtube videos, since 99% of them have surveys = FAKE
2) Never trust information from blogs, or just domains that mention a jailbreak especially the ones that when you google *cfw 4.11/4.20* are the 3 first results.
3) For your own sake don't download any unchecked .PUP file this will cause a nice brick.
Obviously if something like that happens to you an unlucky brick for your desperate search of a solution and testing everything you download from unknown sources, we will give our best to help you.
But take note of this, we are nor responsable in any way of your brick neither your rage if something goes wrong.
We are just trying our best to help BUT if you start harrasing or insulting other members when somebody gave you a hand you will suffer the consecuences of your own actions. Just in case read the rules again = RULES
Neither We can't create a massive awareness move just to alert users NOT to try certain things.
That's why you, me, everyone have freedom of choice, you can test anything but not come here with some bad attitude since the information you got IT'S WRONG.
The choice is yours.
When the solution will be released? or the Jailbreak?:
1) We don't know.
But one thing we know, when the solution came up eventually you will see it on the banner and all over ps3hax site.
So if you are patient user, you will get you reward. Think that many of you like me and so many others are in the same position.
Stuck in certain OFW with no news at all.
The best you can do is INFORM yourself and be aware of any progress being made.
