[Samsung Galaxy S7 Edge Guides, News, & Discussion] Owenboy89:
Hey everyone.

I have recently rooted and installed the Pixel experience 9 custom ROM on my S7 edge.

Even though I am confident in Installing ROMs and using TWRP I always like to have a check on the net to see the best way of doing stuff. When checking I found that there were so many different guides that the process became more confusing than it needed to be and it caused issues when I was trying install the ROM.

So I have decided to write out a guide to help everyone in the future.

Note. I am in UK using a Exynos version of the S7 edge. I believe there is a complication with the USA Snapdragon version.

Also this is done at your own risk and I am not responsible for any damage, errors or bricked devices. This will also void the warranty of your device.

What will you need

1. A computer with a SD card slot (if you don't have a slot you can usb a usb adaptor)

2. The latest version of ODIN

3. Your chosen ROM zip

4. Magisk Root zip

5. The correct TWRP file for your S7 or S7 edge

6.The latest version of your Stock firmware (this is in case something goes wrong)

7. A spare micro SD card with SD card adaptor

8. Micro USB cable (charging cable usually does the job)

9. Samsung Device drivers

This guide will be split in to 4 parts with some additional notes at the end.

Part 1- on your PC

Part 2- on your mobile

Part 3- In ODIN mode

Part 4- In TWRP

On your PC

1. Download and install the latest version of ODIN to your PC. https://samsungodin.com/

2. Download and install the Samsung Device drivers.

3. Download the correct TWRP version for your phone. https://twrp.me/

4. Now Download your root file, I used to Magisk root but there is super SU as well. I was told that Super SU is dated compared to Magisk.

5. Now download your chosen ROM. There is lots of different ROMs for the S7 and S7 edge. In my case I decided to go with Pixel experience 9, it's basically a Pixel 3 ROM that runs Android P but it's up to you.

6. Go to Sammobile and download the stock Firmware for your device. The download takes ages so I would just leave this download in the background and continue to the next step (You shouldn't need this file but you will need it something goes wrong)

7. Put your micro SD into your adaptor then insert into your PC into your SD card slot, then copy the ROM Download and the Root download SD card to the card.

8. Open ODIN and put the TWRP file on the AP section, then uncheck re-partition.

On Your Phone.

1. Before plugging up to the PC there are something to do first. The first thing to do is enter developer options by taping build number 7 times. Then check USB debugging and then check OEM unlocking.

2. Back up your data with Samsung backup and Google backup, both found in the settings.

3. If you already have a SD card inside your phone remove it and put it somewhere safe.

4. Power off your device and Boot in to ODIN mode (volume down, home button and power at the sametime)

In ODIN mode (READ THIS CAREFULLY)

1. BEFORE pressing start on your computer, hold volume up and home button.

2. Now press start on the computer, keep your fingers on the volume button up button and home button. Let the PC and Phone start it's process.

3. The moment the phone screen goes black. Press and hold the power but while keeping your fingers on the volume up and home button.

4. Keep all the buttons held down (volume up, home button and power button) till you see the TWRP screen boot.

In TWRP.

1. Once TWRP boots you will see a screen it will say "swipe to allow modifications" DON'T swipe just press "read only"

2. Press wipe and then press format data. Once the wipe is complete DO NOT swipe to reboot. (You will get yourself stuck in a boot loop) press the TWRP home icon instead.

3. Press Reboot then press recovery this will complete the installation of TWRP (if you press anything else you will get stuck in a boot loop)

4. Allow TWRP to reboot. You will be presented with the "swipe allow modifications" check the do not show again box and swipe.

5. Now insert your Micro SD card with the downloaded files.

6. Press wipe, then press advanced and check cashe and

dalvik cashe. Then Press TWRP Home icon

7. Press install and navigate to SD card. Then press the on the Magisk file and swipe, allow the process to finish and press wipe cache and Dalvik cashe.

8. Press TWRP home icon and press install and navigate back to SD card. Then press your ROM file and swipe again. Once it's finished press wipe cashe and Dalvik cashe. Then swipe to reboot.

9. Re-insert your memo card you were using before. (Not the one with the downloads on, the one with your photos and music and stuff)

10. BOOM your done. Happy days with your new ROM.

Few last things

the ROM I installed had G-apps preinstalled with the ROM, but if your ROM has no G-apps then once you booted, download G-apps from your ROMs browser and flash them with TWRP.

If you get stuck in a boot loop use your stock firmware file and Odin to reinstall the stock firmware and try the whole process again.

This method uses SD card to install the files in TWRP but I believe you can just copy the files via your PC directly to your phone at point 5 in the TWRP part of the guide. I had a spare card so I used a card.

The principal of this guide can be applied to other Samsung devices but newer device then the S7 and S7 edge have more factors to take note of, so some research will be required.

Remember

this is done at your own risk and I am not responsible for any damage, errors or bricked devices. This will also void the warranty of your device.

Hope this guide works well for you.
