Question [HELP!] Needing to flash OP9 back to stock, but I have some issues...

[lazylovesxda]

Trying to flash my friend's phone back to stock but having some issues, you might have seen twixyfig's post in the OnePlus 9 Pro threads, but it's a regular OP9 and not the Pro.

Anyways, I have been trying to flash to working condition but MSM won't help. It keeps saying "No valid trg ID" and "Param preload" for a while now. This happened because we tried to root the phone but failed. The bootloader is unlocked, and fastboot works too.

TIA.

Whenever you post asking for help, always make sure to add as many details as possible. Your phone model, variant, current firmware, the tool you are using, the tools you used before, the steps you took before you started facing issues, every detail you can possibly tell. Only then someone might be able to help.

Download the MSM Tool (Global) from this link. Global works on Chinese variant (LE2110) too. Have proper drivers OnePlus drivers installed. Turn off your phone and set it aside, do not connect to PC yet. Run the MSM Tool exe file. Once its loaded, click Start and it should wait for device. Now on your phone, hold vol+ and vol- buttons (no power button), and connect the cable to phone. This will make the phone enter EDL mode. The PC would recognize the device (USB plugged in sound) but phone screen would still be black. On MSM, the flashing would start and would be done in about 4-5 mins. Good luck.

I think you were trying Indian MSM Tool. That might be the problem.

When your open MSM Tool, choose Others as login.
