This is really frustrating for me and I need help. Since Wednesday evening my WhatsApp has refused to work with any network even when I have gigabytes on both Glo and Etisalat . It started all of a sudden, messages won't enter or deliver when I send . I can access all other web bases stuffs and browse . I have updated it and even delete and install new one . I can't even finish the installing until I used my friend phone as a WiFi. That's the only way am able to access WhatsApp nw .am using Techno Boom J8. Who else is experiencing this .. Geeks in the house ,help me out please . Thanks

since you said you have uninstalled and installed it again and the problem persist and u were not able to use ur data and finish installation i will advice you to factory rest the phone
let it come back to normal as it was when you bought it new

OK bro. Its really crazy bro. The thought of losing all my files is disheartening . pls is there any other means ??

that's y u need backup

Moving all of them to my system nw . Thanks
