Hello everyone! This post will talk about macOS endless recovery mode, errors 1008F, 2003F, 2004F and how to overcome them.
Such errors can be found when trying to perform Internet Recovery on your Mac, and there are many reasons for this action. In my case, it was like this ..

This whole story took me about three days in total, so if this post saves someone at least a drop of time and nerves, it will be great. Nevertheless, please pay attention: what was described above happened to me, you may be different. All actions you perform at your own peril and risk. On my own - I would recommend that before reinstalling macOS, enable booting from USB - drives, unlink Mac from accounting and install from a USB flash drive. Do I regret not doing this myself? - No :)
I wish you easy updates, downgrades and generally fewer bugs and lags.
