How to Install OrangeFox on MediaTek A/B Devices Without a Recovery Partition

I need guidance on the proper working method to install OrangeFox Recovery on MediaTek devices that use Dynamic Partitions (A/B system) where there is no dedicated recovery partition.

On my MediaTek device (Tecno Spark 8 Pro running Android 11), the recovery is integrated into the boot partition (recovery-in-boot/ramdisk configuration). I understand that traditional installation methods like fastboot flash recovery won’t work since there’s no separate recovery partition.

What I’ve tried with limited success:

• Using TWRP’s “Install Recovery Ramdisk” feature from Advanced menu
• Flashing via fastboot flash boot (but this replaces both boot and recovery)
• Various installation methods through existing custom recovery

My specific questions:

1. What is the correct and proven method to install OrangeFox on MediaTek devices with A/B Dynamic Partitions?
2. Should I use fastboot boot orangefox.img to test temporarily before permanent installation?
3. Is there a specific OrangeFox build type required for recovery-in-boot devices?
4. How can I ensure the installation doesn’t cause bootloops since recovery and boot share the same partition?
5. Are there any MediaTek-specific considerations for OrangeFox installation on such partition layouts?

I’m particularly interested in methods that have been successfully tested by the community on similar MediaTek devices with Dynamic A/B partitions and integrated recovery.

Any detailed step-by-step guidance or links to proven tutorials would be greatly appreciated.
