I rooted my oneplus 8 and then it lost wifi. I tried to download the new firmware than it got stuck at qualcrash. Then i tried to fix it but now it’s stuck at fastboot. If i hit start it reboots to fastboot. Can someone help me with this please?
U must press volume up and power to force reboot then when the screen goes black press volume up and down at the same time while plugging in cable that will put u in edl mode.
Then use msm tool for your device to un brick it.
Us this but read it first and make sure it’s for your device
