How to Install and Mod Touch Screen Drivers on Allwinner A13 Tablets
Allwinner A13 is a popular chipset for low-cost Android tablets that have a 9-inch touch screen. However, some users may encounter problems with the touch screen drivers, such as inverted or unresponsive touch, or compatibility issues with certain ROMs. In this article, we will show you how to install and mod touch screen drivers on Allwinner A13 tablets using a simple method.
The first step is to identify the model and firmware of your tablet. You can do this by checking the settings menu, or by using an app like CPU-Z or Droid Info. You should look for the board ID, which is usually a combination of letters and numbers, such as Q8-V12 or 86V2G-V1.1. You should also note the Android version and kernel version of your tablet.
The second step is to download the appropriate touch screen driver for your tablet. You can find them on various online forums, such as XDA Developers[^1^] [^2^], or on websites that offer Allwinner A13 firmware downloads. You should look for a file named \"touchscreen.ko\", which is the kernel module for the touch screen driver. You should also check the comments or reviews of the driver to see if it works well with your tablet model and firmware.
The third step is to copy the touch screen driver file to your tablet's internal storage or SD card. You can do this by connecting your tablet to your computer via USB cable, or by using a file manager app on your tablet. You should create a folder named \"touchscreen\" on your tablet's storage, and paste the \"touchscreen.ko\" file inside it.
The fourth step is to install and activate the touch screen driver on your tablet. You can do this by using a terminal emulator app on your tablet, such as Terminal Emulator or Android Terminal. You should open the app and type the following commands:
The first command grants you root access, which is required for this process. The second command remounts the system partition as read-write, which allows you to modify it. The third command copies the touch screen driver file from your storage to the system folder. The fourth command changes the permissions of the file to make it readable and executable. The fifth command inserts the touch screen driver module into the kernel. The sixth command reboots your tablet to apply the changes.
The fifth step is to test and calibrate your touch screen. You can do this by using an app like Touch Screen Test or Touch Screen Calibration. You should check if your touch screen responds correctly to your inputs, and if it covers the whole screen area. If not, you may need to mod the touch screen driver settings using a hex editor app, such as Hex Editor or Hex Editor Free. You should open the \"touchscreen.ko\" file with the hex editor app, and look for values that control the orientation, resolution, and sensitivity of your touch screen. You should change these values according to your needs, and save the file. Then you should repeat the fourth step to reinstall and activate the modded touch screen driver.
By following these steps, you should be able to install and mod touch screen drivers on Allwinner A13 tablets easily and quickly. However, you should be careful when doing this process, as it may void your warranty or damage your device if done incorrectly. You should always backup your data and firmware before attempting any modifications, and follow the instructions carefully. a474f39169
