The_Rock90, Mar 3, 2018 : I am on Open Beta 22, Oneplus 3T. Please help me with this. Dont direct me to any thread or stuff. I have had done enough research on the same as well. But the phone is not starting, not even flashing led light, not charging. not going to bootloader, flashboot etc. I have read threads where (https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/), my phone might have been hard bricked. So tried this stuff>> but in this stuff as well, the Mobile is remaining undetected on the PC as well. Can't do anything. The Phone was not damaged internally or externally by any kind ever. always used in spigen case and hardly dropped my phone. No water damage as well. Didnt try to root as well. Please mention a solution to this. I called customer care, they said they will have to check and replace motherboard mostly and the device is just 1 month off warranty.
