With the release of the PS4 4.05 Kernel exploit this week, Owners of a PS4 running firmware 4.05 can now enjoy a variety of hacks and mods.
One of the issues of running a lower firmware PS4 is that, unless you’re signed in to the PSN, you cannot use the web browser directly (there is an existing trick, though, which consists in loading the user guide through a proxy, which is something you can see demonstrated in our tutorial on how to run payloads on the PS4).
Enabling the browser however seems to be a simple registry setting, or in other words a saved config entry on the PS4. With a hacked PS4, it is possible to set that variable on the PS4 to re-enable the Webkit browser. And you only need to do it once, the fix is permanent.
Re-enable Webkit on PS4 4.05 – permapatch
- Download the EnableWebBrowser405.bin payload (MD5: 08a064bbe5be2cdc0424a1cd5062a214 )
- Send the payload to your PS4 following our guide.
For those who are worried about what this does, or who want to give a try at compiling their own payloads, here’s the code (courtesy of CrazyVoid, via zecoxao):
#define KERNEL_REGMGR_SETINT 0x4CEAB0 uint64_t *(sceRegMgrSetInt)(uint32_t regId, int value) = NULL; sceRegMgrSetInt = (void *)&ptrKernel[KERNEL_REGMGR_SETINT]; sceRegMgrSetInt(0x3C040000, 0);
Please note that at the time of writing, I have not tested this release yet.
