Installing an Android ROM with your Mac via Heimdall and bash

Because every time I want to flash a new ROM, I forgot how I did it the last time.

This is how I re-flashed my unbranded Samsung Galaxy S4 (german black edition) with a stock ROM (because Cyanogenmod crashed my phone all the time). The correct Stock ROM for my Galaxy S4 is: I9505XXUHOJ2_I9505OXAHOJ2_I9505XXUHOJ2

Software you need

• adb
• heimdall (brew cask install heimdall-suite)
