How do I access the browser on PS4 1.76 without updating?
- Make sure you’re on firmware 1.76. The exploits have some hardcoded values that will not work on lower firmwares. You can get the 1.76 update file from here.
- If you’re on 1.76 but still have the issue, some people are recommending that you reboot your PS4 before trying again.
- Others say you might have to go into safemode: safemode [Initialize PS4 (Reinstall System Software)] with the PS4UPDATE.PUP (1.76 Recovery)
Web-browser on old 1.76 fw (without PSN of course)
- There are two ways, described from D-ecks on how to run the browser from 1.76 without updating your console as follows:
There are two ways to get web-browser works:
1. Edit HOSTS file on you router. You need router with OpenWRT, DD-WRT firmwares or any firmware that's allow you to edit /etc/hosts file on router. Add string below at the end of HOSTS file:
Then open: Settings -> User's guideCode:manuals.playstation.net 188.8.131.52
2. Without editing hosts. You need open Users's guide then scroll to page footer, click "support", on next page click Sony logo (not PS!) , scroll to footer, press G+ and go to g+ page, click on menu in top-right corner, select google search.
If you don't see G+ icon - change country on sony's main site to Russia or Turkey or United Kingdom.
I can make more detailed instructions about router setup, if it's interesting not only for me.
