Please note that SY has Type 1 display screens and LY have Type 2 Displays screens installed in the cameras.
Instructions are are in my "How to Recover your Bricked H? or H?R camera made SIMPLE.pdf easy to follow PDF Manual. Note ?=2/3/8/9/H8 Plus/H8 Pro/ H8s/ H9 Plus/H9 Pro.
If your camera firmware does not have the BKA/BL/BS/BT/BTA/BTR/EKA/EKEKA/EKR/LY/LYR/MKR/RS/RY/RY-LY/SSR/SY/XKR/XTR lettering, please do not update. It is likely your camera is a clone, and it will brick if you use the improper Eken firmware on it!
All downloadable firmware will be displayed as WEB_XXX, only firmware direct from the EKEN factory will display EK letters and WEB_ and the Factory firmware will have "STD_" in it.
This is to prevent leaking of original EKEN firmware, so all firmware Updates, will be displayed as WEB_XXX versions.
