Brought my Galaxy S Note 10.1 Back to life!
My tablet was stuck on bootloop for a few months, and after flashing every stock ROM file I could find, I found that it was the motherboard that was faulty.
The repair was easier than I thought, and it took less time than I thought! It was my first time repairing hardware so it was really exciting to see all of the parts and be able to make sense of them.
Take a picture before you take everything apart to use it for reference later on. Keep all your screws in one place so you don't lose them. And be extra careful with the wires and stips you disconnect!
