Unfortunately you cannot dirty flash from other ports, although you can back up your data temporarily with Samsung Smart Switch PC (This makes it like you never even erased it)
Firstly, Please flash the latest stock Bootloader (BL) and Modem (CP) on your device with Odin3.
💡 If you are unsure as to where you can get your stock firmware from, we recommend Samfw.
💡 Tip: to save time, turn off Auto Reboot in the options tab in Odin
Once Odin says Pass carry on to the next step
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.
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 and press the tick button on the keyboard to reset.
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.
Now that you're back in TWRP do the following steps
Start off by going into Advanced --> ADB Sideload and swipe to start ADB Sideload
Once you have started ADB sideload it should look like this
Now that you have ADB Sideload running, Plug your phone into the computer you're planning to use.
After that, Locate your downloaded platform tools and extract it.
Once you have extracted your platform tools go into the platform-tools directory
Once you are in that directory go to the top of the file explorer window where the path is, click it and type in cmd
After you have done that a new command prompt window should have opened to that directory.
Now that you have that command prompt open, type in adb sideload and then drag the repartitioner zip onto that command prompt and press enter
After the repartitioner is complete, your device should reboot back to recovery.
Repeat these steps from here again but with the cleaner file.
Once the cleaner is complete, you are ready to proceed to the next step.
Now that your device is properly partitioned for this ROM, we can now install the actual ROM itself!
This is pretty much the same as the repartitioning step but we don't have to flash an extra file.
Go into Advanced --> ADB Sideload and swipe to start ADB Sideload
Once you have started ADB sideload it should look like this
Now that you have ADB Sideload running, Plug your phone into the computer you're planning to use.
After that, Locate your downloaded platform tools and extract it.
Once you have extracted your platform tools go into the platform-tools directory
Once you are in that directory go to the top of the file explorer window where the path is, click it and type in cmd
After you have done that a new command prompt window should have opened to that directory.
Now that you have that command prompt open, type in adb sideload and then drag the ExtremeROM Nexus zip onto that command prompt and press enter
Once the zip is finished installing press "Reboot System" and you're good to go!
