Please make a video about installing custom bootloader on Oppo A55 and custom roms

Hey Lee I have been your subscriber for about 6/7 years and I have rooted my several android phones like samsung note 5/ Redmi note 8 and several old phones. Please help me this time as its very hard to unlock bootloader on Oppo phones and there’s no working tutorial. I own Oppo A55 CPH2325 and its 4gb ram and its started lagging after 4/5 months and I want to root my Oppo A55 and install custom roms to get rid of ColorOS to install lightweight custom rom.
Please make a video about installing custom bootloader on Oppo A55 CPH2325 (Android 11) and custom roms.
I will be very thankful if you upload the tutorial video on your YouTube channel for this problem.
