I replaced the motherboard/optical drive on my ps4 and now its asking for system update using a usb for version 3.00 or later. I formatted my usb for FAT32 and downloaded the update from the plastation.com website and put it in the file format PS4->UPDATE->PS4UPDATE.PUP it gave error code (CE-35952-4) this didn’’t work. Then I tried the exfat format with the same file path, and that did not fix the problem either. Both were attempted in safe mode, I have tried all of the other options from the safe mode menu and still the system will not load properly. Please help and thank you for doing so.

There is a good chance that you have the wrong update file loaded onto your drive. When you are on Sony’s website the first one you come to is not the right file (It’s for the most current UPDATE…you need the entire system software)…the file you need is located near the bottom of the page. When you get close to the bottom of the page you’ll see this: “Perform a New Installation of the System Software” That’s the file that you need. Just be sure to reformat your drive and follow the rest of the instructions to a T. I hope this helps. Post back here if you still need more help. Good luck!

I used a 2 Gb Usb rather than an 8Gb one and it worked fine thanks guys

formatting to FAT32 and not EXFAT plus downloading the 980MB file again did the trick for me ((:

Ok so…. I had a power outage the other day my ps4 was on. I didnt want to turn it on again because of the possibility that it could go out again. So the next day I go to turn it on and it says that I need to install the update file via usb, disc or internet. I booted it in safe mode and tried internet (with lan cable). ,,update file 7.51 available” I press it to update. First it downloaded the update, then it started applying it. After that it restarted and checked my HDD again and I was at the beggining. Did it a couple more times. Tried with USB (FAT32 , 4 GB storage abd everything named and downloaded corectly) the ps4 got it, downloaded the update, applied it and after restart - nothing. Back at the beggining, checked the HDD and it just doesnt want to update. Says update complete and when it restarts it doesnt want to boot. I really dont want to factory reset it, because I have so many clips and other files that I want to keep. Is it possible to update it without wiping the whole HDD. I need answers. Thank you beforehand.

I finally got mine to work after hours of try and looking up stuff online with no luck. I renamed the file “PS4UPDATE.PUP” before I put it in the “UPDATE” file (usually I was naming it after placing it in the file). I didn’t delete the old file that was in there. A message came up that I was downloading a duplicate file named “PS4UPDATE.PUP.PUP” So my computer already applied the .PUP so I didn’t need to add it to the file name. So I removed the .PUP and just put in “PS4UPDATE” and to finally worked. Hope this helps.
