Hello man i am using OnePlus 8 T-mobile.
Can you tell me all the steps please how to install this rom?
Here is what I had to do
Prerequisites.
Make sure your phone is backed up!
1. Unlock Sim (
Good Guide for a few of the below steps)
To do this first your phone/account much meet the requirement on this
page. Once your have met those requirements you can follow this
page to unlock your sim.
2. Install
Android SDK Platform Tools
Use the above link to download the tools and extract the folder to somewhere accessible. You will access it through the process.
3. Unlock Bootloader
If you don't know how to enable USB debugging you can use this
guide. While in the developer options go ahead in a enable OEM Unlocking. If you have trouble with the device not showing this
guide can help you get the drives.
- Copy down your IMEI
- Plug phone into your PC and accept the debug prompt on your phone
- Then the Platform Tool fold right click and open windows terminal.
- Enter the command adb devices (I had to add ./ for any commands to work). If nothing shows up check the driver.
- Enter adb reboot bootloader
- Enter fastboot OEM get_unlock_code and copy down the code
- Use the code to fill out this form and wait a week for it to be approved.
- Once the request is approved save the unlock.bin to the platform-tools folder.
- In the terminal with your phone booted into the bootloader enter fastboot flash cust-unlock unlock.bin
- When this completed enter fastboot oem unlock
- Then fastboot reboot. Your boot loader is now unlocked
