Samsung Galaxy Player 5.0 / Galaxy S Wi-Fi 5.0 YP-G70: Installing Entropy's Daily Driver (custom kernel) for overclock and ext4 support

May 14, 2012

The Samsung Galaxy Player 5.0 is making a lot of commotion these days in the developer community. One of the latest development hacks for Samsung’s portable media player is Entropy512’s Daily Driver kernel by XDA Developers member Entropy512.

Entropy’s Daily Driver kernel features a lot a lot of performance upgrades and contains a heavily modified version of ClockworkMod Recovery. Not only that, the said kernel also comes with an overclocking feature that allows you to push the boundaries of the Galaxy Player 5.0 up to the limits.

Here is a complete list of features found in the kernel:

  • coolbho3k’s Samsung Sleep of Death patch – allows stable use of screen-off profiles with limits below 800 MHz in SetCPU
  • netarchy’s conservative governor tuning patch – Reduces the polling interval, allowing conservative to ramp up/down faster.
  • conservative set to default governor – use SetCPU or a similar app to change it
  • jhash3
  • TinyRCU
  • CIFS and Tunneling modules included
  • ext4 partition mounting support in kernel and initramfs thanks to rumirand – ghetto Lagfix baby!
  • CWM based recovery – Mostly tested, seems working, but may have a few bugs still to work out, rumirand helped a lot on this one
  • Insecure kernel – gives you automatic root in ADB shells
  • Per-file fsync() disable capability – see “dangerous features” documentation below
  • Standard bootanimation (/system/media/ support
  • Charginghacks – faster charging at low battery, slightly slower near the end, overall faster charging while trying to minimize battery stress
  • CPU core voltage control – use SetCPU or a similar app
  • CPU overclock to 1.2 GHz – use SetCPU or a similar app
