    Hello All,

    Really need your help on this issue~ So feel free to pop out anything that you can think of.
    OnePlus 7 Pro 12GB 256GB

    So my phone was charging(100%, was about to unplug it), but all of a sudden it went dead, not powering on. I wasn't even using it, no drop, no water, no nothing.
    I've tried the following steps:
    - Volume up + Power button(it starts the phone, but it does not boot into the OS and turns off after 5-10 seconds.)
    - Volume down + power button(does not boot into recovery mode)
    - Volume down + volume up + power button ( it gives me the Qualcomm CrashDump error)
    - Charged it for about 4 hours, not responding at all
    - MSMdownloadtools to unbrick (it won't recognize the device, stuck at waiting for device, seems like the EDL mode doesn't work on my phone)

    There's once that the lightning sign(the symbol that pops up you are charging when phone is off) , came up for two seconds and went away.

    I don't know what to do now~
    Please help~
    Thank you guys in advance!

    You might need to get the phone sent in for repair, sounds like hardware failure. https://oneplus.com/support
