Even you send us the oldest iPhone 2G (1st Gen)
We still can do it...
This time a customer sent in a iPhone 4S which failure attempted repair from other shop.
After a brief checked on it. Found out the previous repairer replaced the Power IC.
And the iPhone still unable to power on.
By looking carefully at the board, the other side of Power IC is CPU. This is very heat sensitive area. If an amateur technician try to replace the Power IC with incorrect temperature or method, it will cause CPU problem. CPU problem will cause iPhone unable to boot up.

| There is a cracked line on top CPU. Usually it happened because of other side too hot and this side CPU bloated |
Means there is two layer for this IC.
So the problem is this top of CPU cracked and bloated.
All i need to do is replace the SD RAM.
Honestly to tell you that iPhone 4S doesn't worth to repair since Apple stop giving new iOS on it. Unless you have some important data need to recover.
Yes.. This customer do have important data must need to backup. We quote him RM 250 to repair. Market value of iPhone 4S is about RM350 - RM450.
It's consider fair price to him and me (worth of my time)
Done. Lucky all the data still remain.

| Ready to mount on top of CPU. |
Done. Lucky all the data still remain.
Forgot take picture. But we care customer privacy so usually we don't take photo of inside.
