My take on this is that microsoldering repair is about:
- Knowledge and experience in troubleshooting. For this you need a DMM, brains, google, schematics, and some tears. Start with basic components (what are resistors, caps, filters, diodes, etc.). Move to circuits like backlight circuit, touch circuit, etc.
- Microsoldering tools. The cheap ones are the Japanese Hakko. Cheaper will introduce more variables.
- The skill to use the tools. Be able to replace small components and micro BGAs. Lots of frustration.
- Parts.

What does it matter if you have everything you need except one of the above? I know I need a 2.2K pull-up resistor because my brains and my DMM and my schematics told me so. I can see it looks bad in my $700 scope. I have the tools and skills to replace it. But I don't have a replacement. That part is like $0.01 and yet my phone will not boot without it.

What does it matter if you have everything you need except one of the above? I know I need a 2.2K pull-up resistor because my brains and my $150 DMM and my schematics told me so. I can see it looks bad through my $700 scope. I have the tools and skills to replace it. But I don't have a replacement. That part is like $0.01 and yet my phone will not boot without it.
Or I have it, but am not skillful enough to replace it and instead heat the board too much and kill it.
All the above mean serious investment in time and money. Just that you know what you're up against.
Many have done it.. it is far from impossible, but it does take dedication like everything else you want to learn in life and be good at.
