this one first you need to have skills , electronics stuffs and experience repair phone before.
next sometime is just " hit and miss " come individual at home fixing phone. Partly you don't have those " standard machine " to Diagnostics on Your smart phone ". of course you can make it work but can last longer is another thing this is why I claim " hit and miss ' maybe lucky you make it work last longer maybe just work for one week break down again

This is why those repair shop offer min One month warranty after service.
