N950F Exynos how to root Oreo please?

[jeremyf50]

Good Morning,

I have a carrier unlocked Australian N950F Exynos Note 8 running 7.1.1 with OEM Unlock showing in developer settings (took a week or so). My phone has downloaded but not yet installed this OTA:

N950FXXU3CRC7/N950FOLN3CRC7/N950FXXU3CRC7 (1021.03MB)

I think it'll be Oreo but I haven't checked which exact version.

I have not installed TWRP or rooted this phone yet but I'd like to do so. I'd also like to move to Oreo before I proceed as my battery life could be better.

What is the best way to proceed? I've read through some long threads and ended up confused about exactly what's the best procedure.

Is some kind or decryption required at some point? Will I lose the data currently on my phone?

I haven't installed the OTA update yet.

Thank you.

CRC7 is Oreo, 8.0 which is currently the latest for Note8 (8.1 may be a long while out if we even get it officially).

The process for rooting Oreo is basically the same as Nougat, for Oreo just be sure you are using the updated TWRP that fixes the data mount issue.

If you root Nougat first, you won't be able to update OTA so you'll then need to install a custom rom to get Oreo.

You can update to Oreo via OTA first & your data will be intact but regardless if Oreo or Nougat, after installing TWRP you'll need to wipe data to remove encryption. So yes, you will loose data. You won't loose internal or external storage unless you choose to format them but it's a good idea to make a backup of them just in case.

As for data, you'll need to use smart switch, helium, etc if you want to back it up. I have no experience with backing up data without root so I'm not sure what methods work best.

It seemed to work. I restored all my contacts, apps etc in Oreo. When I went to restart the phone and enter TWRP to flash magisk I get a message about only official binaries are allowed. Now the phone won't even boot. I'm guessing I now need to re-flash official firmware with odin just to get my phone working? Another week for OEM unlock? I waited this long because I thought the problem was resolved

Unfortunately if you have the OEM lock issue, that will never go away. So yes, you have to flash official firmware to boot again. If you were on Oreo, you can try flashing Nougat to see if you might get lucky & get OEM unlock back.

Since you have the OEM lock issue, remember to always flash the RMM state fix even if you flash a custom rom that has the fix built in. Always flash RMM fix right after flashing a custom rom. If not flashing a custom rom, flash RMM fix before booting to system after you install TWRP.

Thanks for the reply.

Was I supposed to install Samsung AntiRoot Removal and RMM State Bypass as per this guide? Is this guide the correct method?

I'm currently downloading Oreo 8.0 XSA (unbranded Australian rom) to reload my phone and wait another week.

I would like to use the XSA Samsung rom rather than a custom rom. Is OEM Unlock available in Oreo after a week?

Thank you

I use the method listed in any of the TWRP threads. I've never heard of Samsung Anti Root Removal. By the sound of it on the page it sounds like dm no verity. You need to flash that & RMM state fix. Flash the XSA firmware you want to use. Log into your Samsung account, don't reboot for 168hrs & OEM unlock should appear. Then follow a guide for installing TWRP.
