    I recently aquired Galaxy tab 2 7.0 GT-3113ZW from another party I did a factory reset on it and when I set up my own account it uninstalled kingroot, which I did not even know was on the device at the time, with a prompt 'uninstall harmful app'. After this, it will no longer allow me to load any websites or connect to play store or Galaxy apps. I can connect to WiFi and also to my hotspot on my phone, but when I try to load anything or sign into certain networks, it gives me the message 'cannot establish secure connection'. Please help, I have tried to reinstall kingroot APK and use it to properly unroot, which seems to have worked successfully, but am still having the problem with internet connection. I am not sure if the root/unroot is even related to the problem, but I know the issue wasn't happening before kingroot was initially uninstalled.

    You'll need to flash a stock rom for the device

    How can I do this if I do not have a PC and am unable to connect to the internet?

    Sounds like the security certificates were deleted or damaged. You'll definitely need to re-flash the firmware.

    Can you beg, steal, or borrow a PC that is online?
