Installation Guide

ExtremeROM Nexus Installation Guide

Requirements:

• A Computer with the required Samsung USB Drivers
• Odin3
• ADB Platform Tools
• The phone itself (duh)
• A USB C cable with data support
• A functional brain

In this guide the S10 will be seperated from the S20/Note20 so that it is easier for the end user, if you would like to skip to your device use the sidebar located on the right.

⚠️ To complete this guide make sure you have your bootloader unlocked already, I will NOT be going over that in this guide.

Galaxy S10

Restock your device

Firstly, Please flash the latest stock ROM on your device with Odin3.

When you flash stock with Odin put the HOME_CSC in CSC and put the latest OdinPack TAR Archive in USERDATA slot

⚠️ Make sure that your Odin looks like this with all the files in it (S20 Ultra used here as an example, but it is the same throughout devices.)

💡 Tip: to save time, turn off Auto Reboot in the options tab in Odin

Once Odin says Pass carry on to the next step

Reboot to TWRP

On your device you should see its on the Downloading... screen (if you turned off auto reboot)

While the phone is still connected to the computer, hold the bixby button, power button and volume down button at the same time. After the screen goes black carry on holding bixby and power but instead of volume down hold volume up instead.

If you don't get into TWRP on your first try, turn it off and try again.

Prepare for flashing

Now that you are in TWRP, navigate to the wipe button, then press format data.

Type yes into the promt with the provided on-screen keyboard.

Go back to the TWRP home page and tap on wipe once again, then slide to factory reset.

Now go back to the TWRP home page once again, Press reboot then recovery.
