Best Black Friday Deals at: AT&T, Sprint and Verizon.

If you want to improve the performances of your Acer Iconia Tab A700, now you can easily do so as CM10.1 custom ROM has been made available for your tablet. I know that most of you are expecting CM10.2 instead, for installing Android 4.3 on your device, but until a stable version of the platform will be made available, the present Android 4.2.2 JB update should do the trick. Therefore, if you want to safely install CM10.1 firmware on your Iconia Tab A700, use the present step by step guide.

The Android 4.2.2 Jelly Bean based CM10.1 platform is stable and works without bugs or issues on almost all the Android based devices out there. Well, the same can be applied when talking about the Acer Iconia Tab A700. The update will embrace your tablet along with important features and apps that will optimize the performances of your handset. Therefore, after completing this guide, your Iconia Tab A700 will run faster, will provide an upgraded battery life and will offer more power.

As you know, a custom ROM is unchaining the internal system of the Android devices by offering access to internal settings, in built programs, features and so on. So, with CM10.1 installed on your Acer Iconia Tab A700, you will be able to use your tablet without dealing with carrier restrictions or with any other security tools. In a few words, everything that’s installed on your device can be changed, customized and optimized.

As you can already tell, for being able to apply this ROM on your tablet, you will first have to gain root access. Be careful when doing so as root is also an unofficial operation that can brick your device. So, use suitable root guides that can be applied on your Iconia Tab. Then, return here and resume the rest of the guidelines.

After gaining root access, you need to install a custom recovery image as the stock one is useless when installing custom ROMs. I recommend you to flash CWM or TWRP recovery, these being the most used custom recovery for the Android system. The custom recovery image is essential for this guide, as by using the same CM10.1 will be flashed on your Acer Iconia Tab A700.

Another recommended operation is the backup procedure. You see, during the proper steps a wipe will be required. You need to reset the system of your device which means that all of your data that is saved on the internal storage memory will be wiped out. So, before doing anything else, try to perform a full backup. Do remember that CWM recovery is now running on your handset, so don’t hesitate and use the same for saving the current ROM too.

Other than that: a computer must be used as the firmware file must be downloaded on the same; also your tablet and its USB cable will be required; deactivate the antivirus, antimalware and Firewall protection along with any other security protection that is running on your computer; go to “settings -> applications -> development” and enable the USB debugging option on your tablet; charge your device if there is less than 60% power left – else skip this line.

Your handset is now prepared for the installation procedure. Do remember though that this step by step guide is compatible only with the Acer Iconia Tab A700. So, use the next steps for flashing Android 4.2.2 Jelly Bean based CM10.1 custom ROM only if you own the mentioned tablet. Using this tutorial on a different device will probably brick your Android based smartphone / tablet.
