Could be main board damage (smc was knocked off by drop or something along those lines) or the connector on the main board was damaged or if you're frame is bent or damaged it could be shorting out.

I’m guessing it’s CPU Issue

And compute benchmark score value is zero

Well it's probably main board not CPU. If it was CPU the odds of it booting is so low. Probably time for a new phone.

You are right but I spent more than $200 for this minor repairs

That’s the reason I can’t go for another phone

If I got solution this issue will fix it nd sold

Kindly tell if any jumper option to get fixed this issue

Gekozen oplossing

There are several power rails that power the Rear Camera, U2501 being only one of them. Check to insure that U2501 is properly powered by VDD_BOOST and then check the other rails in the image below.

Any jumper solution can work on that

Like remove U2501 IC and put jumper between A1 & A2 will work?

"Jumper solutions" are not solutions. You need to invest some time to understand what U2501 is (hint...it's an LDO) and what it does (hint...it takes VDD_BOOST and regulates it down to 2.9V).

If you jumper the input and the output of U2501, what happens?

Okay, thank you

I had small clarification kindly mention in detail

Is this rear camera unit connected to A10 cpu

Because previously I reballed
