Just over a week ago we heard rumors of accessing the PS4 Debug Mode Settings on retail PlayStation 4 consoles, and today scene developer CTurt confirmed it's now possible to access the PS4 Dev Menu on 1.76 retail units thanks to Flat_z! :D

Download: Enable Dev Menu / PS4-dlclose.zip / PS4-debugmenu.bin (1.0 MB Compiled) via fx0day / PS4-debugmenu.bin (1.0 MB Compiled) via Di_Scala_ / Tutorial by Chaos Kid / PS4-dlclose GIT

From Stuart Fox via Facebook comes a video demo also.

:arrow: Update: From lezek20 also comes code to enable the more advanced debug menu (dlclose.bin (1.00 MB) compiled by ultradogg), to quote:
Code:
*(char *)0xFFFFFFFF833242FD = 0x81;
Just add it into the kernel payload before this part:
Code:
writeCr0(cr0);
:alert: This could brick your console btw, so be careful!

:arrow: Update #2: From @j0lama with help from @sealab (Demo video: jgoake.mp4 - 43 MB) via Twitter:
Download: Fully-Enable-Debug-Settings.bin (1 MB)
Code:
Fully enable Debug Settings:
*(uint32_t*) 0xFFFFFFFF8269C07Cull=0;
*(uint32_t*) 0xFFFFFFFF8269B56Full=0;
Thanks to B7U3 C50SS and GrimDoe in the Shoutbox for the heads-up! :)

But the important thing is what you can do with the holes...

Dude that Sounds nasty XD
No more broke back mountain for you l
this is a reason why sony will push to the market the new PS4 NEO
because now ps4 has alot of holes
nomatter what system they keep pushing out every system will have holes and even if there arent any its easy enough for some1 experienced to make one and make it a complete security breach .

These are instructions for creating a MIPS cross-compiler toolchain based on
GCC 4.9.1, Binutils 2.24, and Newlib 2.1.0.


Required Files
--------------

- binutils-2.24.tar.bz2 (http://ftp.gnu.org/gnu/binutils/)
- gcc-4.9.1.tar.bz2 (http://gcc.gnu.org/mirrors.html)
- mpfr-3.1.2.tar.bz2 (http://www.mpfr.org/mpfr-3.1.2/)
- mpc-1.0.2.tar.gz (http://www.multiprecision.org/)
- gmp-6.0.0a.tar.bz2 (http://gmplib.org/)
- newlib-2.1.0.tar.gz (ftp://sources.redhat.com/pub/newlib/index.html)


Environment Requirements
------------------------

- Linux, BSD, Cygwin, or another Unix-like environment.
- Recent compiler tools (tested with GCC 4.x series).
- Bash or a bash-like shell (or adjust the instructions below).


Procedure
---------

Note that PREFIX is the location in which you will install the MIPS compiler
and other tools. You can modify it to be anything you like.


1. Set environment variables:
export TARGET=mips-elf
export PREFIX=[any directory]/mips32/mips_tc
export PATH=$PATH:$PREFIX/bin

2. Unpack everything:
bzip2 -dc binutils-2.24.tar.bz2 | tar xf -
bzip2 -dc gcc-4.9.1.tar.bz2 | tar xf -
bzip2 -dc mpfr-3.1.2.tar.bz2 | tar xf -
bzip2 -dc gmp-6.0.0a.tar.bz2 | tar xf -
gzip -dc mpc-1.0.2.tar.gz | tar xf -
gzip -dc newlib-2.1.0.tar.gz | tar xf -

3. Move (or symlink) GCC dependency packages
mv gmp-6.0.0 gcc-4.9.1/gmp
mv mpc-1.0.2 gcc-4.9.1/mpc
mv mpfr-3.1.2 gcc-4.9.1/mpfr
mv newlib-2.1.0/newlib gcc-4.9.1/newlib
mv newlib-2.1.0/libgloss gcc-4.9.1/libgloss

4. Build binutils:
mkdir binutils-build && cd binutils-build
../binutils-2.24/configure --prefix=$PREFIX --target=$TARGET --disable-nls
make
make install
cd ..

5. Build gcc:
mkdir gcc-build && cd gcc-build
../gcc-4.9.1/configure --prefix=$PREFIX --target=$TARGET --with-newlib \
--without-headers --with-gnu-ld --with-gnu-as --disable-libssp \
--disable-nls --enable-c99 --enable-long-long --enable-languages=c
make
make install
cd ..

At this point you have a complete toolchain located at $PREFIX.
After modifying the Makefiles of the software demos to point to $PREFIX
you should be able to compile them.

You can tell where his mind is at this early lmao. The sounds of slivers lol
