What more i can do?

SeanB:
I would suspect the 74ACT08 Ic IC7, and C10, as those are the most likely thing to fail, and then RTC does not update, which is detected by the BIOS.

PS
Do not take pictures handheld, use any camera support.

1st image is not working board image , 2nd image is working board one.

Also have you checked the reddit : https://www.reddit.com/r/ElectronicsRepair/comments/1g9csou/what_more_i_can_do/

Harry_22:
Please put both boards side by side, clear your phone lens, put it on any suitable box, hold your breath and make a good photo.
May be you will get the best quality if take one by one photo.
It would be good to see chip names near the side connectors.

Also I would to discern dip switches near IC15 as well as chips in red circles.

I have usual Chinese phone. You can see the test photo below.

Your fist photo was very good.

8-pin Mini-DIN connector near the dip switches is for keyboard.
