yesterday I tried to reset my rooted phone (LG Optimus 4X HD) because I thought it would run faster after a factory reset.
Unfortunately I didn't remember that I uninstalled the stock keyboard and now, there is no keyboard installed on the device. This makes it impossible to get past the setup wizard.
I tried sideloading a keyboard apk via adb but it failed (error message: verifying package ... installation aborted). I also failed to connect the device to the PC suite (I presume this is the case because USB debugging is turned off).
Is there anything else I could try?
Thank you in advance
