Jeez, sounds like you got scammed.
Where did you buy this and how much did it cost you? If on eBay, open a case to get your money back.
As to install CFW, you can do it with any Launch model easily in 5-10 mins and early Slim models. Top Loader model only run HEN.
It was off a Facebook retro selling/buying group to which the seller was a "reputable" seller/buyer, but hey ho, I got removed and banned for putting up a post about this as the seller seemed to have blocked me when I sent a video of the console crashing on instant boot.
So yea, its clear to me this prick knew his console was faulty and figured while its working for now, best off selling it and get some money from it.... something I hate about retro sellers, then they have the balls to block you off the group so they can carry on scamming people.
Bad enough that money is very tight, unable to work no thanks to having cancer and its fucked my body up, I am like an 80 year old trapped in a 32 year old body.
So I'd like to at least try fix this myself without or is it fixable as I have already wasted money buying a brand new 1tb hdd for it.
Or if it is fucked beyond repair, my memory and brain is slow as fuck recently - so before I go buy another PS3 I will be avoiding the likes of ebay, amazon, Facebook and will likely end up paying more from Cex, but at least it will be covered with a 24 month warranty.
But I cant check the console model exactly if I buy online or in store.
But I do have a contact in customer service who is very helpful and has helped me in the past to hunt down specific items and have it sent to my local store.
So I could fire over an email asking him that I am looking for a PS3 console that must be this model and on or below this OFW.
But I dont know exactly what PS3 model I need to ask for that is compatible to install CFW.
The PS3 I had was on an older firmware which I updated to 4.89 CFW.
Id prefer CFW installed than an exploit FW, I was going to look into doing my sons PS3 which is a super slim, but I haven't checked what firmware it is on, but im confident it will be below 4.89 OFW.
Id assume with his been a slim that it likely isn't compatible to install CFW and will need the other method.
