Please help my Tamagotchi 4U

[janejira]

I got this Tamagotchi for my son( 9 years old)..and he was so happy and played with it as well for 3 months.

But last time after Tamagochi re-born again..and this egg never hatch! Just bouncing around from a day till a week!!
Even I changed new batteries..tried to set up the date (birth day now)..still don't hatch out

I guess the time is not running..that why tamagotchi never comes out
This Tamagotchi for you have any mode or process to restart everythind from zero as come out from factory?
I pressed ABC and reset and do everything couldn't I checked in guidebook..also didn't find any solution.

Please anyone tell me what should I do?

You will have to replace the clock, which requires soldering a new clock on it. On the front of the circuit board is this cylinder shaped part

I think I understand what you mean..but I don't think that I able to do it.

Once I tried to open this 4 screws ..but I don't have any idea to do with this board.

Maybe I'm better to send to a guy to fix it

Thank you anyway

It happened to my mix and I only had it for 4 months, I eventually sold it to a girl on the tamagotchi amino and she fixed it! I'm happy it works and found a new home.
