My only suggestion for improvement would be to provide more detailed release notes or changelogs for each update, so users can better understand what's new and what's changed.
Finding a legitimate requires patience and careful matching of your hardware ID. Do not trust the first Google result. Instead, verify your MCU version, cross-reference on 4PDA or XDA, and always keep a backup of your original firmware (dump it using SP Flash Tool ) before installing anything new. caska software update link
