Safe Kernel for AOSP-Based ROMs on the Epic 4G Touch

For those who haven’t heard, there have been some issues with Samsung ICS leaks and brick bugs. The Samsung Epic 4G Touch was no exception to kernel- and recovery-related issues. When CM9 ROMs were were first coming out on the Epic Touch, they didn’t come with a custom recovery. To flash to a different ROM, users had to flash a Gingerbread kernel containing the proper ClockworkMod recovery, and then use that recovery to flash to a new ROM. This is because the kernel being used suffered from similar issues as the hard brick bug on other Samsung devices. Thus, it meant that trying to wipe and flash a different ROM could result in a hard brick. That problem is now solved.

XDA Recognized Developer chris41g along with XDA Senior Member FranceIsBacon are currently building AOSP-compatible kernels with patched ClockworkMod recoveries. To put it more simply, they have disabled the emmc_cap_erase, which has been identified as one of the big troublemakers in the whole brick bug debacle. The purpose of this is to allow users to flash an AOSP-based ROM, flash their kernel, and then use that recovery to flash to whatever else they want without fear of bricking their devices.

Currently, the kernels are considered to be in the testing phase. They do work and users have reported as much, but none of them are good enough for Chris41g to declare stable. On top of being for AOSP-based ROMs and having a patched recovery, the kernel also has a number of other features including:

New Schedulers
SIO
VR
New Governors
LulzActive
SmartassV2
Hotplug
Pegasusq
CWMv6
Patched eMMC
Battery Tweaks
Speed Tweaks

So if you’re running AOSP-based ICS ROM on the Epic Touch, you may want to look further. Those interested should head over to the original thread.

CloudPlayer: DIY HiFi Music Streaming Solution

In our Helpful Guide to Music Streaming Services, we mentioned several different services that offer ways to stream catalogs of music directly to your device. While each service has their benefits and drawbacks, the common theme among them is to give you access to a vast library of music without the need to store your own, and charge you a monthly fee for the privilege. But what if you already had access to your own catalog of music? Sure, there...
