You can get basically any part from Shenzhen with an Alibaba account, if you know what you're looking for.

For reaching out to a seller/merchant, I found it helps significantly if you google translate into Chinese, and just communicate in Chinese.

Yeha, it's the "know what you're looking for" part that a random guy in a near-warzone in Ukraine will know.

> know what you're looking for

A modern cellphones have only about 10 replaceable assemblies[1] - repairers aren't typically replacing individual broken chips, an entire assembly/part. "[knowing] what you're looking for" is easy of you know what broke the device, or following basic troubleshooting steps.

Getting into repairs these days is easy; YouTube, Alibaba, Forums/File-sharing sites, USB-C and Open Source firmware-flashing tools have conspired to lower the bar of entry. If you have an old phone in your device drawer with a damaged screen or unusable battery, you probably can fix it yourself, with the right tools and some patience.
