Hello, i live in china so i bought the chinese OnePlus 6 because the french online support told me that they will can help me to flash it, but in fact they only can do it if i am in europe.
So i tried the max tuto : how-to-unroot-oneplus-6-using-stock-firmware-twrp/
I m not sure if i have the right TWRP app ? i have TWRP Manager and i can’t give him the root permissions.
SO i tried the fast boot solution : how-to-unroot-oneplus-6-using-fastboot/33
But i m really lost XD
Step 1. Power off your OnePlus 6. = it’s ok
Step 2. Make sure your USB cable is DISCONNECTED! (as if it is connected to your computer it will enter a hard-brick unroot mode) = it’s ok
Step 3. Hold down Volume Up and Power buttons together until you are in Fastboot mode. = it’s ok, it s put me in a strange screen as we can see here https://www.youtube.com/watch?v=TlHA_lFNJzw
Step 4. Connect a USB cable from your OnePlus 6 to your computer. = i connect the USB during i’m in the strange fastboot screen ?
Step 5. Unzip the stock firmware zip file you downloaded.= that’s ok
Step 6. For Windows, simply double-click on flash-all.bat and wait 10 minutes. DO NOT TOUCH ANYTHING! = I’m still in the strange screen, usb is connected, then i double click ? it’s opened the windows CMD but no text, just black screen. I waited 10 minuts then i stopped it
For step 4 and 6 i m a little lost
If someone can help me thanks coz i can not live without google~
