Question How to flash stock rom from custom rom

[spamerobaldomero]

Hi there,

Bought this beast of phone like 8 months ago easily but after installing several roms and suffering so many bugs (with cr-droid the camera never worked at 4k 60fps i.e.) and app crashes, now I need something stable 100% so want to go back to stock rom.

However couldn't be able to find any tutorial about that, so I'm a bit confused with this problem. Which are the steps to do that?

Thanks in advance

Iam a little hesitant to use , when I go into read the bat file it states

ECHO # Oxygen OS Flasher For OnePlus 9RT by abhinavgupta371 and HELLBOY017 #
ECHO # updated by Va1d3m and penguinus

I just want to be sure it has been configured for the op9p

I would just use the MSM tool to go back to stock rom. With phone in USB debug in CMD type adb reboot edl when you have your phone plugged in and the MSM tool open. Once MSM tool recognizes the device just press start. After going back to stock rom update to latest firmware

I realize, but it would be nice to quick toggle between diff versions and returning to stock without using MSM, so that's why I am questioning what the android file host says it is versus what the fastboot rom says it is in the .bat file,,,, edit,, answered my own question went from 13.1 back to c_65 and everything looks good, and its asking me to upgrade to f.17 if I want,,,, edit,,,, and just doulble checking that msm still works after using fastboot rom and it does

I used those several times without problem
In any case, at the end, you should go via MSN

It went well with the fastboot roms going from 13.1 to c_65 ,then I msm to 11.10 and tried to go back to 13.1 via fastboot rom and it didn't like that,, it soft bricked to bootloader loop so I had to msm again via magisk,,
