I have this used Dell desktop I’m trying to use but it’s protected by a BIOS or HDD password. Is there any way I can reset...

I have a customer with some eTalk flip phone from verizon and it is currently having an issue where it automatically...

No it does not need the front camera connected to turn on

If you didn’t disconnect the battery while doing the screen repair, you probably shorted out the backlight circuit resulting in no backlight or a “blank” screen. You’ll need a board repair specialist to fix this issue as it results in a blown fuse or capacitor within the backlight circuit. It is not a repair you can DIY as it requires a lot of skill and thousands of dollars in tools.

Well since you now have a black screen, the answer should be pretty obvious. You need to buy a new screen. The S10 plus uses OLED panels and whenever you break the screen whether it’s just the glass or you get a black screen, the only way to repair it is to replace the screen. OLED is very thin and fragile which just makes it difficult to repair.

A battery replacement most likely won’t fix your issue. Whenever there’s excess heat, it’s a typical symptom of a short somewhere, especially if it gets hot to the touch. Was the device ever dropped in water?

The XS max will not display the display message and as long as you transfer over the ear speaker assembly from the original display to the new one you’ll maintain FaceID

As stated by the comment above, it really won’t be practical to add that extra slot. Although the board already has the pads there, you’ll need additional components to go with it on top of the proper BIOS to support it and thousands of dollars in microsoldering equipment with the skills and patience to do it. Microsoldering is like performing surgery on electronics. You’d be way better off getting a machine that either has what you’re looking for, or maybe even swapping out just the motherboard.

I’ve seen this before. When you ordered the replacement port did you order one that corresponded with your model? Samsung has been known to use a few variants of charge ports and camera assemblies depending on model. If you didn’t use the correct port, it will give you the “no sim” message despite there being a sim card installed.

Can you post a message of the error message you're getting? If it's a "service battery" message it usually means you used a cheap battery or one that may have a defect. If it says "Apple is unable to verify this is a genuine battery", that may be fixed by the JCV. I’ve replaced dozens of 8 series batteries with good quality batteries from Mobile Sentrix and have never gotten that message. The devices will report max battery capacity just fine too.

There are 4 microphones found in the 8. Two at the bottom on the charge port, there’s one on the front facing camera assembly, and one by the rear camera assembly. I would start with replacing the charge port to essentially replace the two bottom mics. But before you do that, clean out the wholes at the bottom. Sometimes those can get clogged with dirt.

The only way to rule out whether it’s the camera or motherboard is to try a new camera. If a new camera works, well that should be pretty self explanatory. If a replacement doesn’t work, then you probably have a board level issue.
