General [SHARED] [UNOFFICAL][Stock Oxygen OS][Fastboot ROM][Firmware]OOS11.2.10.10 and OOS 12(C47)

[cbrown666]

What's this?This is a stock oxygen os fastboot Rom for OnePlus9 adapted from https://xdaforums.com/t/fastboot-rom-unofficial-op9rt-oxygenos-a-04-a-07-for-mt2110-devices.4404719/ .I really appreciate @Valdem for his flashing script for OnePlus 9RT.And I modified his script according to OnePlus 9 partitions and changed some flashing order in script.

Note that this is only for the device which is unlocked bootloader.And internal storge may be cleaned if you downgrade from higher oxygen rom or come from other rom like custom rom.

The ROM's image is extracted from oos11.2.10.10BA and oos12(LE2113_C47) ota package.Note that the ROM is only for ONEPLUS9(LEMONADE).

For full package oxygen os:
Flashing instructions:
- On your PC, install bootloader drivers for OP9 and check if device is recognized in Bootloader and Fastbootd modes.
- On your PC, download the Fastboot ROM zip from the download link below.
- On your PC, unzip downloaded file
- On your PC, navigate to its now-uncompressed folder
- Reboot your OnePlus 9 to bootloader mode.
- Connect the OP9 to your PC
- On your PC open command line window in the uncompressed folder,
- double click flash-all.bat
- wait till PC shows "pause" on terminal.
-Whether to format data is depend on which rom you stayed before. If upgrade from older oxygen os or on the same version oxygen os,no need to format data.Otherwise format data and reboot phone.

For firmware package:
Firmware package is used for whom wants to install custom ROM.And flashing firmware package by using this instead of MSM can streamline the procedure.After the PC shows "pause"on termianl,firmware package has been installed completely.Then following the custom rom install procedure-flash boot boot.img.If not boot into recovery,replace phone into bootloader mode,flashing dtbo and vendor_boot partitions will work.
The using procedure is same as full package.

NOTE:Before using this fastboot ROM and Firmware,you must have a compatible boot.img which can flashing images in fastbootd mode.Oherwise,install the "boot.img","dtbo.img"and"vendor_boot.img"by using "fastboot flash boot boot.img","fastboot flash dtbo dtbo.img"and"fastboot flash vendor_boot vendor_boot.img"in phone's bootloader mode.If phone don't boot into recovery or fastbootd mode,flashing firmware(If target is OOS11,then flashing oos11.2.10.10 firmware;If target is OOS12,then flashing firmware OOS12C47).After this,reflashing boot,dtbo and vendor_boot.

This script uses fastboot, not recovery. Custom ROMs typically post the recovery image to use for flashing them in the thread if you're asking about that.

Any one success in flashing OOS11.2.10.10 or OOS12(C47) by using this script?

Fastboot scripts are the quickest path to bricking and having to use MSM in my experience so I'm not trying it. If you do, make sure you switch to slot A first because for some reason, slot B really doesn't like to cooperate on this device.
