A few days ago, I had same problem with Samsung S8. When the phone was turned off, and I connected to the charger, a message appeared on the screen about moisture in the charging port. I checked the charging port and I found some black dirt inside. I used tooth brush to clean but it did not reach the bottom of the charging port. Then I used a PCB cleaner ESD brush. It is stronger then a normal tooth brush, and it reached the bottom. After 5 minutes cleaning the problem solved. Sometimes I had to use a thin pointed tweezer to reach all the dirt on the bottom. The dirt was some black sticky material. That caused the moisture message.

Disconnect everything from the logic board and try to start it with connected charger. If it is not start, disconnect the charger, and try to start with connected battery. If the board still not start, most likely your board is faulty. If any of your other part faulty (like battery, keyboard, ssd etc, your board will start on this way.

First try to reset SMC (system management controller). SMC is responsible for the energy management of your mac. If it is not help, probably your battery is faulty.

If the glass scratched, the best solution is to change the whole screen. It is not expensive and you can do it easily. On this way your front camera will take good pictures again. During the repair you can clean the camera and camera lens on the front glass inside and outside, and your pictures will be even better in the future.

If you replace iPhone 8, 8 plus or X screen you need to copy the firmware data of the original screen into the new screen. The needed tool is under development. I saw some working versions, what are tested and working with IOS 11.4 and 12.0 Beta. The screen data can be cloned only to OEM screens for now. Afte the copy of the data, the light sensor works well again.

That is possible to bypass FRP on Samsung S8 quite easily. The description would be too long so just follow the steps of this video: https://www.youtube.com/watch?v=9qcBBQ4r...

If the "No SIM" message changes to "Searching", when you put your SIM card to your phone, there is a good chance to fix this problem. Sometimes the SIM card just not connect to the SIM reader properly. Open up your phone, and gently push down the top of the SIM reader. If the phone find the network now, it is just a simple connection error. Remove the SIM card, bend the top of the SIM reader and put back the SIM card. The top of the SIM reader will push the SIM card to the pins of the reader. If it not helps, try to change the charging block. The signal comes from the rear case, it goes through the charging block, and goes to the board. So if there is no signal and the sim connects to the sim reader probably, the faulty charging block is the problem. Sometimes the rear case faulty, but that is very rare.
