Once you get your device into Recovery mode, you can install the Silk browser. To do so, you'll first need to transfer the SilkPort files to your device, either by connecting your rooted Android device to your PC via USB or by loading the SilkPort files directly onto a memory card and loading the card into your device.

Next, use an Android file manager app like to copy all the files in the /lib directory of the Silkport file pack you downloaded to the /system/lib directory. Once they've been copied to your device, you'll need to set their permissions to match the other files in the system/lib directory.

The final step is to install the Silk browser app itself. The SilkPort file package contains multiple .apk files, and you'll need to install them all on your device. You should be able to do this by tapping them in your Android file management app; just make sure that you have Install From Unknown Sources enabled in your device's Security settings.
