General advice for getting into phone repair - GSM-Forum

Hello guys,
I am interested in getting into phone repair. I hope you can clarify some of my questions. Firstly, I might tell you a bit about me:

I've been involved with electronics for a long time now. I'm developing all kinds of electronics myself, am very used to reading schematics, soldering, PCB layout, electronic components. So I think the repair itself won't be the problem, after I gathered enough experience with all the problems and soulutions in the field of smartphones. I do have a lab with all the common tools, also a hot air soldering station. I would probably have to buy a microsope, an ultrasound cleaner and schematics, at least.

What I'm asking myself right now:

I'm planning to buy broken phones to repair them and get experience, for a start.
Which brand should I start with?
In which ways can iPhones be locked, so that they're not fully usable after a repair? (What I found: Simlock, Touch ID, iCloud, FMI)
Which of these are a problem, or can be overcome? I would prefer selling fully working phones, that aren't locked in any way.
When talking about iPhones, which generation would you start with?
How do you source good quality replacement screens? (I'm afraid this question can't really be answered...)
How do these chinese sources for schematics work? I came across "Wu Xin Ji" for example. Does such a dongle make the software work for a year, or does it work for lifetime, but only not update after a certain time? That's very confusing to me and the Aliexpress desciptions don't help at all. Do all of the Dongles on Aliexpress work? Louis Rossmann uses Openboardview for example, which I would favor as I'm using Ubuntu Linux.

I hope someone will be so kind to give good advice

I'm really used to do a lot of research on the internet, but I think it would be very usefull to get some clarification on these issues for a good start.

Best regards,
adrifromhh
