Hello, how can I fix this problem?

To open up this device i need to remove the 3 plastics holding the pcb?

You did not describe which version of TH05. And all TH05s have one cover that is removed to replace the battery. TH05_V1.4 is the worst. Has high battery consumption. TH05_V1.4 is not worth buying.

I unfortunately have the TH05_V1.4, so can I flash it through ota? Sorry if I’m asking but the Google translation of the page is kinda bad 😅

From the Tuya version, everything is flashed via UART.

To flash TH05_V1.4 firmware, you must completely remove the printed circuit board. Same thing with TH05F. Other models do not require this.

It’s really hard to perfectly short reset with gnd 😅, is it possible to program that using arduino uno with removed atmega?

I managed to make it work. It’s now unfortunately showing Error read revision. I am using Windows and shortening the vbat-(connected to gnd) with REST_N. Is there something I can do to make it work? Thank you in advance
