Intro

This is a (Linux) step-by-step (no-root needed) tutorial on how to install LinageOS on Galaxy-S7, using FOSS tools. (That worked for me)

Preperation

Before getting started, you will need to:

Install TWRP

Once you downloaded TWRP .img file based on:

Model Region/Processor Model Number
Galaxy S7 (Exynos) Global/EU SM-G930F
Galaxy S7 (Qualcomm) China/USA SM-G9300, SM-G930V (Verizon), etc.
Galaxy S7 edge (Exynos) Global/EU SM-G935F
Galaxy S7 edge (Qualcomm) China/USA SM-G9350, SM-G935V, etc.

(WARNING: The table above is mostly CHAT-GPT generated) (See: Settings > About Phone)

  1. 📱 Connect you phone
  2. 📱 Press "power + volume_up + home" until Download-Mode (Odin-Mode) appears
  3. 📱 Press "volume_up" to continue
  4. heimdall flash --RECOVERY ./Downloads/twrp-XYZ.img --no-reboot
  5. Wait until it's (100%) done ...
  6. Now finally and most importantly! press "power + volume_up + home" and imidiatily after the screen get black 📱 Press "Power + volume_down + home". If not TWRP appears you must redo the aobve 1-6 steps because "The stock ROM will overwrite the custom recovery with the stock recovery..."

Install LinageOS

Assuming you followed TWRP installation steps and already downloaded LinageOS, "Swipe to Allow Modifications" and select:

  1. Wipe > Format Data > yes
  2. Wipe > Advanced Wipe
    • Dalvik / ART Cache
    • System
    • Data
    • Cache
  7. Swipe to Wipe
  8. Navigate back
  9. Swipe to Factory Reset
  10. Wipe > Format Data > yes
  11. Home > Reboot > Recovery

Now connect phone to PC and move lineageos zip file into the "Internal Storage". If not mounted automatically then select 📱 "Mount > USB Storage". If the phone won't appear automatically in your PC (like in my case) you may need to manually aft-mtp-mount ~/mnt/galaxy_s7, but if you find your PC's file-manager freezing when you move any file to it, redo steps from 1-11. If still having the issue (as in my case), just move the file to an external SD and insert it to the phone. Alternatively use adb tools to push the file [...] finally:

  1. Install > Swipe to Confirm Flash
  2. Reboot System
  3. Done
