[support] OP3T will not turn on at all after flashing OOS Beta 9 after a soft-brick

[Bonk2]

Hello everyone. I updated my rooted OP3T (with TWRP installed for recovery) to OOS 4.0.1(I think? I know for sure it was 4.0.x) a week or so ago using a VPN as I live in the US and today I got the new update for whatever version that was about 30 mb, and after I rebooted I got stuck booting into TWRP so I followed the guide linked underneath here and got up to step 12 (flashing beta 9) and after swiping to restart my phone will not turn on in any way, shape, or form. Whenever I plug it in/unplug it from my computer I'll still get the Win10 device connected/disconnected sound and if I hold the power button for long enough while it's plugged in I'll get another device connected sound or disconnected, usually followed by the opposite sound. There doesn't seem to be a pattern to the sounds, but if anyone knows what's happening I really need help with this as it's the only phone I was able to afford and if it's bricked I don't know if I have the money for another one. Thanks

Lol no wonder your phone doesn't work anymore. You flashed the beta to the OP 3 onto your 3T. Use this to fix your phone.

Edit: Sorry if this was of use to some people when it was deleted.

I tried to use that thread, but my phone wouldn't show up underneath Unknown Devices, in fact unknown devices would never come up at all. my pc is still in test mode from this :/

Don't worry if it doesn't appear under unknown devices. Just use the tool. A lot of what the instructions say is unnecessary. Just make sure that when you plug in your phone that one of the ports becomes "active" (I haven't had to use this tool in months, so I'm not sure exactly what it's supposed to say exactly) and press the start button.

Sounds like you flashed the wrong version of Oneplus 3 firmware to your phone. Do you have a 3 or a 3t? If you flash the incorrect one you will get exactly the unbootable state you describe. In that case you will have to use Qualcomm MSM Downloader tool to flash back the correct ROM and firmware partitions to get it running again. Just download the correct MSM recovery package for your phone and follow the instructions in the thread.
