Flashing custom ROMs on a OnePlus 13R Ace5 - yashaswee-exe/AndroidGuides GitHub Wiki

1. Backup all your data to an external source. All your data will be wiped.
2. Make sure to remove pin/password and logout of google accounts.
3. You should have same firmware on both slots. If you are coming from OOS/COS you can either use regional/super flasher (here) to flash oos/cos on both slots. If you are not comfortable with this, local install the current firmware version.
4. Download the custom rom.zip.
5. Dump the zip to get the individual img files, if not already provided by the developer.

• If it's a fastboot ROM, you can just extract the zip and get the img files directly but if it's a recovery ROM you need to extract the zip and dump the payload.bin > follow this guide.

6. Make sure you are using the latest platform tools for running adb/fastboot commands.

fastboot flash boot boot.img

fastboot flash vendor_boot vendor_boot.img
