G_Khulood_Khan_jHtn, Jun 8, 2019 : My OnePlus 3 suddenly stopped working and now i am not able to boot it up. On pressing the power button all i get is a black screen with a Chinese text 已进入rf测试 which translates to "Has entered the rf test..." I have tried MsmDownloader tool for oneplus 3 to completely unbrick it, still the same text appears. I even tried sideloading the latest OxygenOS with no luck. I can go in the recovery mode and fastboot but nothing helps as i can't get it to boot up properly. What's the mistake here, has anyone encountered a similar problem? If yes then please do tell what needs to be done. My area doesn't have any service center for Oneplus phones so i can't get official support.
