Soft-bricked LEM5 after TWRP flash

I’m new to these smartwatches, and it was my fault for not reading these forums, but I ended up rooting with Kingroot (app installed bloatware lockscreens and other junk; I’ve always used SuperSU so never again with Kingroot) and then I flashed TWRP that I grabbed from XDA just via fastboot command line.

My LEM5 is bootlooping in TWRP and showing the text:

“Done processing script file, renamed stock recovery file in /system to prevent the stock ROM from replacing TWRP.”

It’s just in a loop within recovery, so I have no idea what I’m going to do to fix this.

Your flashing method is wrong!
On MTK based phone/watch it always suggested to use SP Flash Tool.

I didn’t know any 100% working TWRP on Lem5; could you give the link, please?
