Flashing this Wiko y50 / Sunny 4 w-k130 flash file (stock firmware) will restore your phone to its default factory state. It will remove root, virus, un-brick, and fix your device if it’s stuck on boot logo. If the phone lags, after flashing it should be better.
You should consider making a backup of your current firmware, and all other important data on the phone, because flashing this ROM will erase your phone. Also, you should only flash your device if you actually know what you’re doing. To avoid messing up your device, or turning it into a brick.
It’s also important that your device is charged up to at least 30% so the process is not interrupted due to shutdown.
