Make Your Own Heat Sink for the LG Optimus 4X HD

Posted by wicked December - 17 - 2014 - Wednesday Comments Off

Optimus heatsink

It’s not a rare occurrence that performing a resource heavy task on your Android device (e.g. playing a game or multitasking heavily) results in the back of your device getting quite hot due to the heat being generated by the CPU. And without proper or adequate heat distribution, this heat will be most prominent at a certain area of your device’s rear. Strong heat is not the only downside of a hot CPU however, as it can also result in decreased performance due to throttling, less battery life, and a lower overall device longevity.

With this said, XDA Senior Member ottomanhero figured out a very clever way of remedying this issue on his LG Optimus 4X HD after noticing that playing games on this phone results in a certain part of the phone’s rear getting hot. He pinned this down to unequal distribution of heat behind the back cover, and decided to tape aluminum foil around the back to direct heat from the hot area to cooler areas.

After conducting tests with this homemade heat sink in place, ottomanhero found that he experienced much better and lower temperatures emitting from his device. There was also an issue with the device’s GPS signal being weakened as a result, but later resolved this with a new method. Ottomanhero has provided a picture that clearly shows this modification, and has also written a detailed tutorial teaching you how to do this yourself.

If you would like to give this a go, head over to the LG Optimus 4X HD homemade heat sink thread to get started.

XDA is not only a great source for custom ROMs, kernels, and various modifications for numerous devices–it’s also a great place to find tutorials and other materials that help you to understand the Android ecosystem better. These resources then help you on your quest of eventually becoming a developer. Every developer started off not knowing how to code, but learning and ambition can work wonders.

Creating your first project can take days or weeks if you are learning just by yourself. You can reduce this time significantly by following the video tutorial by XDA Senior Member sylsau. By following this guide you will become… a time traveler and change your currently used dialer to classic rotary style seen back in the old days of last century.

The project has been built on Eclipse, so if you’re planning to follow the guide, you’ll need to download the IDE yourself since Google dropped Eclipse and ADT as the main Android IDE. You can watch the video by visiting the How to create an Old School Rotary Dialer forum thread.

Enhance Screenshots Functionality by Adding a Delete Button

Posted by wicked December - 16 - 2014 - Tuesday Comments Off

Screenshot_2014-12-15-04-15-41

Screenshots are the best choice for users wishing to show off their current home screens or provide extra detailed bug reports for certain issues to app developers. Android has a built-in screenshot system that allows you to take a shot with a simple key combination. However, the built-in functionality could easily be improved by adding a delete button, because right now you need to open the gallery manually to delete unneeded images. Taking screenshots on Android would be much easier with a delete button available right after taking a shot.

XDA Senior Member sportik555 wrote a guide explaining how to add such button on Sony Xperia devices. The described method shows how to decompile the SystemUI of your current ROM, make changes, re-compile the file, and send it back to the device. Everything can be done within less than 10 minutes because sportik555 provides the files used in the process.

To make the delete button available on your ROM, you need to ensure that your system is deodexed. Apktool is pretty much useless if your system uses .odex files. You can find numerous guides showing how to deodex easily deodex your ROM. When your re-compiled System UI is ready, all you need to do is restart your device. The delete button should appear every time you take a screenshot.

This method can be used on quite a few Xperia ROMs, so don’t hesitate to learn more if you have an Xperia phone in your collection. You can find all the details in the Add the “Delete” button on the screenshot preview tutorial thread.

Restore Your Softbricked Moto G after Lollipop Update

Posted by wicked December - 15 - 2014 - Monday Comments Off

Moto G lollipop

Being one of the handful of devices released by when Motorola was still owned by Google, the Moto G has finally been updated to Android 5.0 in the past week through an OTA update and an update leak. As Moto G users are installing and experiencing Lollipop, it’s inevitable that some issues would occur, such as a softbrick, especially with the different variants of the device. So, if you’ve managed to get your Moto G softbricked after updating it, a tutorial written by XDA Senior Member GI0\/\NNI may help.

Consisting of 10 steps, the tutorial teaches users how to unbrick and restore their softbricked device after updating it to Android 5.0. It essentially consists of using ADB and Fastboot with CMD and flashing a fresh firmware onto your device, and if you wish, installing the Android 5.0 OTA update again. If however this process is a bit complicated, GI0\/\NNI has also provided another method which involves downloading an Android 4.4.4 firmware, and making a .bat file with the provided code, and using this file to install the firmware. It must be noted that this tutorial is only for softbricked devices, as there is currently no remedy for users who have hardbricked their Moto G.

So, if you’ve gotten your Moto G softbricked after the Lollipop update and want to check this tutorial out, head over to the Moto G Softbrick restore thread for more information.

Learn How to Restore Files and Settings with Flashable ZIPs

Posted by wicked December - 13 - 2014 - Saturday Comments Off

ZIP

There’s an absolute treasure trove of mods we can find, access, and play with here on the XDA Forums–each with their own purpose and effects. Some change the aesthetics and cosmetics of your device’s UI, some enhance the utility and practicality of features, and some are just for fun. However, unless provided, there’s really no way of reverting the changes of these effects other than by backing up your entire ROM, such as with Nandroid backups and restoring them, and this is only possibly if you made a backup before the mod was installed.

With this said, another common way of reverting effects of mods is by flashing a special ZIP package, but this is only available if the mod developer made and provided one. With this tutorial written by XDA Senior Member bloof however, you will be able to create your own flashable ZIP file to revert any mod changes as well as restore any files and settings. Originally written for the LG G2, the methods explained in the guide will work with any other Android device if you disregard the file names specific to the G2, or if you figure out the equivalent of those files. The tutorial is split into numerous parts, each teaching you what files need to be included in a ZIP file for different scenarios, such as fonts, mods, and boot animations. Bloof also lists some files which would be always be a good idea to keep backed up at any time, such as the original kernel of the ROM, SuperSU, and Xposed-Disabler-Recovery.zip.

If you would like to find out more, head over to the flashable ZIP backup tutorial thread for more details.

Relocate the Dalvik Cache to Get More Space on your Moto G with Mod

Posted by wicked December - 8 - 2014 - Monday Comments Off

moto g

Having little to no memory left on your Android device is a bummer especially when you’ve already tried cutting down your files, music, videos, photos and apps to only the very bare essentials (which definitely has a wide scope needless to say). For owners of devices without SD card slots, this can be pretty frustrating, and the non-LTE variants of the Moto G is no exception. This is because the internal eMMC storage of the device has an approximately 600MB partition called /cache, which unfortunately and frustratingly not used because cache of apps is stored in /data. Hence, this leaves 600MB of unused space on your phone.

To access this untapped memory space, XDA Senior Member Bert98 has written a tutorial linking files in the dalvik cache to /cache, providing you an extra 600MB of memory which you would not have otherwise. This solution may not work however, if you have a lot of apps installed, being more than 90 apps, and if you’re running ART. The reason for the latter restriction is that ART uses a lot more memory than dalvik and space in the /cache partition would not be big enough to accommodate this size.

If you’d rather not go through the process yourself, you also have the option of a mod automating this for you, courtesy of XDA Senior Member skyguy126. The installation of the mod varies depending on whether you’re running a stock or custom ROM on your Moto G, and in either case, instructions are provided. Skyguy126 has also provided troubleshooting instructions in the event that something had gone wrong during installation.

So, if an extra 600MB of memory space sounds like something you’ll be interested in, head over to the Moto G dalvik relocation tutorial thread and mod thread for more information.

How to Use a Custom Toolchain for ROMs and Kernels

Posted by wicked November - 7 - 2014 - Friday Comments Off

toolchain-01

Toolchains are basically a bundle of development tools that are used in a chain (the output of one tool becomes the input for the next, and so on) in order to compile source code (in this case, ROMs and kernels). While the Android NDK toolchain (which comes with GCC, among other tools) is usually used for this, developers can also use other toolchains if they wish. These can include optimizations focusing on performance or stability, for example.

Linaro and SaberMod are two popular examples for custom toolchains. They both introduce several optimizations, especially for recent ARM CPUs. If you’re trying to find out how to switch to a custom toolchain, then you might want to check out the tutorial XDA Senior Member frap129 has written. In it, he explains how to fetch the toolchain you want, as well as the necessary changes in order to use it. While the guide uses Linaro and SaberMod as examples, it could be used for any other custom toolchain as well. Interested? Go to the Switching to a Custom Toolchain Guide forum thread now to get started!

Using custom toolchains, even though it may provide significant benefits, can also have a negative impact on stability and introduce bugs that are hard to track down and fix. This is a good thing to keep in mind while experimenting!

If you’re just starting and would like to learn how to compile a ROM or kernel from source, then we’ve also got you covered. Head over to XDA-University, which has tutorials to do just that and much more.
