Enable Force AC (Fast) Charging On Galaxy Nexus With Kernel Patch

Advertisements

If you have a smartphone or a tablet, you most certainly must’ve observed how it charges slowly through a USB connection than through when it is connected to an AC power outlet. I’m not really sure why this is the case (it has something to do with how USB ports draw less power), but chad0989 over on popular Android development forums XDA-Developers has found a way to get AC outlet-level fast charging on Galaxy Nexus through a USB connection by using his kernel patch.

As with all system-level hacks, the Force AC (fast) charging kernel patch requires a rooted Galaxy Nexus. Applying the hack also requires some really advanced skills, but more on that after the jump!

From XDA-Developers:

I put together this patch for you guys at the request of a few different members here in the nexus forum. This allows one to force AC charging for any charger that is detected as USB (i.e. car chargers, inductive chargers through the pogo pins).

When it comes down to actually applying the patch, things aren’t so simple. There is no ClockworkMod (CWM) Recovery-ready flashable .zip file or APK to install. Instead, the developer has simply released a patch that allows developers to integrate the feature into their own custom kernel while compiling. As of writing, we couldn’t find a flashable kernel with support for the feature, but hopefully there will be one released in the future to make the process easier.

Once you have a kernel with Force AC (fast) charging support, you can install IncrediControl to toggle fast-charging from General > Force fast charge. Afterwards, when you connect your Galaxy Nexus using a USB cable, it will charge faster or, to be more precise, as fast as an AC charger.

If you aren’t the sort who knows their way around kernels (developing, not just flashing them), then we suggest you stay away from this mod as this may damage your device.

Head on over to the official thread over on XDA-Developers to read instructions straight from the developer.

How To Install Android 4.0.3 Ice Cream Sandwich With HTC Sense 4.0 On Nexus S

Advertisements

HTC recently unveiled it’s One series of smartphones based on Android 4.0 Ice Cream Sandwich. Hardware specifications and advanced, next-gen optics aside, these devices come with Sense 4.0 – the latest version of HTC’s custom skin – which looks absolutely stunning and a vast improvement over Sense 3.5 and older which were very bloated.

Nexus S-owning enthusiasts interested in trying out Sense 4.0 on their device are in luck as a port based on an RUU leak from the One X has been released. It is currently in “pre-alpha” stage od development since most parts of the ROM do not work.

From XDA:

This is Sense 4.0, ICS 4.0.3. It is ported from the latest HTC Endeavour RUU leak. The Endeavour is a quad-core tegra 3 phone, with 720p display. So yes this rom will take some work. This rom is more of a preview. It has alot of issues.

DISCLAIMER: Redmond Pie will not be held responsible if you lose data or your device gets damaged in the following of this guide. Proceed at your own risk.

Step 1: Download the flashable .zip file from here [Minus Link]. Place it directly under /sdcard directory on your Nexus S.

Step 2: Turn off your device.

Step 3: Press and hold Volume Up + Power buttons until you get into ClockworkMod Recovery.

Step 4: Take a nandroid backup.

Step 5: From main menu, do a (wipe data/)factory reset, wipe cache partition and from advanced menu, wipe Dalvik cache.

Step 6: Once again, go back to main menu. Navigate to install zip from sdcard > choose zip from sdcard and select the .zip file you transferred to your Nexus S in Step 1.

Step 7: After flashing is complete, choose reboot system now.

If you followed the steps correctly, your Nexus S will now boot into Android 4.0.3 Ice Cream Sandwich with Sense 4.0 (taken from HTC One X) on top.
