Guess what? There is a hidden treasure in Google Nexus 7 Android 4.1.2 Jelly Bean OTA system update ~ Asus Keyboard 3.0.0.0. Yes, Asus Keyboard was included in the latest OTA but hidden. So if you don’t like to use stock Android keyboard, you can try out Asus Keyboard instead. Note – root access is required.
You can ignore this article if you did not root Samsung Galaxy S III. Why? Because you need root access to backup and restore Samsung Galaxy S3 EFS. And you don’t need to worry about EFS at all when not rooted.
What is EFS? It is a place that stores your Android smartphone important data like Wi-Fi, Bluetooth MAC address and IMEI (nv_data.bin). Do take note if you are a frequent ROM / firmware flasher or rooted your Android phone. Installed unstable poorly cooked ROM might cause EFS partition to be corrupted or missing. Which will make your Samsung Galaxy S3 fail to make voice call due to missing IMEI number. So better to make a backup of your Samsung Galaxy S3 EFS partition.
CheckROM is one of my favourite custom ROMs for Samsung Galaxy S II. So the very first custom that I tried on Samsung Galaxy S III is CheckROM EvoHD ROM. What makes CheckROM special? It has Kitchen Pro Application which is very useful to customize CheckROM EvoHD ROM even further. You can install custom boot animation, modem, kernel, widget / apps, font and mods with Kitchen Pro. Cook all the ingredients by yourself. Make CheckROM EvoHD ROM a perfect Android ROM that matches your needs.
Why all applications that require root access are not working anymore on my Google Nexus 7? After troubleshooting, seem like Superuser application by ChainsDD does not support Android 4.2 Jelly Bean yet. So I have to re-root Nexus 7 with Android 4.2.1 Jelly Bean (Build number JOP40D). How to root Android 4.2 Jelly Bean Nexus 7? The procedure is the same as previous Android version. Just Superuser application was replaced by SuperSU from Chainfire.
Stock Samsung Galaxy S III kernel is good. However, using tweaked and optimised custom kernel for Samsung Galaxy S3 is better. It improves overall performance and has lot of features that can’t be found on stock kernel. For example, root access, insecure adb, custom boot animation support, overclocking, undervolting voltage control, multiple tweaked CPU governors, GPU overclocking, I/O tweaks, automatic backup of EFS partition, NTFS USB driver support and other more… So here are the top best custom kernels for Samsung Galaxy S3 that you can try.
