ESP8266 deauther watch display wont turn on, how to fix?

Hello. I bought Deauther watch from DSTIKE Y version (version 3). I used it many times but now i connected it to my laptop and arduino and it stopped working. It does get on and it's even fully recharged but the display is completely black. I tried resetting, turning it on/off 10000 times. I even used the reset thing in arduino.ino from DSTIKE manuals. How do i fix this issue? I think i had this issue once too before i even decided to connect it to Arduino.

EDIT: FIXED

hi @dirtyfan2 - welcome to the forum.

Do you think there might be one person somewhere that could benefit from a few words about what the problem turned out to be, and how you solved it?

Since you are new here, you may not have seen this is a place where ppl help ppl. Even a noob can know or find or learn things of value.

It can't be that the 10001st time was the charm.
