Trying to compile as many users who have faced the same issue and to get some data to find a work around.

SM-N950F - Australian (TEL/TEL/TEL) post paid Telstra Note 8.

Waited one week for 'Allow OEM to be unlocked' to appear in Dev Settings.

This is my experience and now have the official binaries issue.

I also got the OEM unlock after one week, this is what happened when trying to install TWRP and Magisk on Stock ROM.

I tried to flash TWRP lost night and that was okay. I decided to hold onto stock and just have TWRP and Magisk at this stage until other roms are a little less buggy. Flashed TWRP. flashed Verity / Magisk, setup phone again and then decided to do a backup in TWRP. When trying to go into TWRP got the message 'Only official released binaries are allowed to be flashed' and then went into a soft brick. Had to restore phone to stock and now OEM unlock has disappeared again, In download mode FRP and OEM lock are both OFF. Tried to reflash TWRP and get the same message - 'Only official released binaries are allowed to be flashed'.

So the plot thickens.

We are on the same boat bro,



Mine is SM-N950F/DS Singapore (XSP), got on Sep 9th via preorder from Singtel.



But I did not notice if oem unlock option was there when I got the device. Then I tried to flash TWRP last week(oem unlock was there), flashed SuperSU 2.82. When I was configuring an app to modify host(to disable ads), the phone rebooted itself before I was able to flash dm-verity, and went into the bootloop with the same msg 'Only official released binaries are allowed to be flashed' [emoji33]

Alright, here's where I'm at after some experimentation.

I received my phone on the 19th, and when I looked in "Developer options" for the "OEM Unlock" option it was not present. A week (7 days) goes by and I look in "Developer options" again and I see that "OEM Unlock" is there. I enabled the toggle that day, and then in the evening I successfully flashed TWRP and noverity. After this I rebooted according to the instructions and I encountered the "Only official released binaries are allowed to be flashed" message along with a soft brick. Reflashed stock firmware to get out of it and "OEM Unlock" has vanished from "Developer options"

Now, a week goes by after this (7days again) and I check for "OEM Unlock" on the 26th. Just like clockwork it's there. This time I flash TWRP, skip noverity, and flash Magisk. I'm able to successfully root and I boot into the system -- I check "Developer options" for "OEM Unlock" and the toggle isn't there. For whatever reason after a while I decided I would reboot and see what happens. I go into a soft brick with the same "Only official released binaries are allowed to be flashed" message. I'm kind of kicking myself, because now I need to wait another week for the toggle to show up so I can make another attempt.

Next week I am going to flash TWRP, flash Magisk, and then let the phone sit there for another week while I wait for the "OEM Unlock" toggle to show back up. Once that happens I am going to see if I can reboot freely or if I encounter another soft brick situation. If I soft brick again I'm fresh out of ideas as a phone that is rooted but can never be rebooted without flashing back to stock is a non-starter.

I'm doing the same as you, I'm still a few days away from week 2. So I'll do the same, flash TWRP and Magisk then try my hardest not to have the phone restarted for any reason for another week. No reports yet of this work around as it's still early in the peace but I know there are a number of users who will try this method. Good luck and I'll post how I go or if someone else posts sooner! BTW did you do a wipe/format before flashing Magisk out of interest? Cheers.

Hey mate, maybe you can try the method a few users are going to do now, after another week and when OEM re appears then redo the process but this time don't boot the device. However I see what happened in your case the phone restarted itself when configuring SuperSU.. I've not hear that happening before. Maybe try Magisk if your looking at trying again? Strange it rebooted by itself. Good luck and let us know how you go.

It's good we're getting to a point where we can collect data and try different approaches. It was a much darker time when we were all sitting around wondering if/when the OEM Unlock toggle would show up! ;)

Yes, I did a wipe/format prior to flashing Magisk. One thing I haven't been doing is clearing the cache/dalvik following successful flash... is that important? I recall doing that back when I rooted my S7 Edge, but I've not seen or heard about anyone doing it since.

You might want to check the huge thread on this thats about three posts from here. Short story it seems if you stay in recovery and install a rom with knox disabled you are good to go. Read more there...

Thanks mate, been reading up there and seen the posts. Looks like Renovate has had most success so far with that method. Looks promising, fingers crossed. I've got another few more days in jail before I get the OEM unlock back.

I don't think anyone has reported a failure yet doing it that way. Still a ways to go on the testing though, It appears folks aren't all that anxious to screw up a good thing once they get up and running. The good news is if ordinary dumbassez like us can get in the smart guys should get something figured out sooner rather than later. Anyhow, good luck, if it's any consolation mine showed up in 5 days...

Thanks for the suggestion mentioned, but what do you mean by redo the process? Or just switch off and then on the oem unlock toggle when it reappears in 7 days after the first flash(twrp and supersu) followed by a reboot(as only via reboot can I judge if it works)?

In addition, in my case the phone restarted itself when I tried to modify host to disable the annoying ads, not during configuring SuperSU.

I will give it a try once oem unlock returns. Hopefully this can be resolved soon. Being in jail sucks. I've tripped Knox so lost Samsung features and no root still so dont have root advantages.

Well I got out of Jail yesterday after getting back the OEM unlock for the 2nd time. This time I decided to 'play it safe' until the smart people figure out what the issues are. This method worked perfectly for me and I've now been flashing Viper, flashing extra fonts, doing backups in TWRP and generally using the phone as normal again. The current Renovate release (r95) has most of the issues fixed and is a good daily driver, also the facial recognition is all fixed and Magisk is working with no issues, I've been able to use my banking apps for over the counter purchases again, tested and all working. Here is the method that worked for me -

How to flash Renovate and not stuff up. Remove SIM card before starting (I got this from Krabman's posts so I was not going to tempt fate at this stage by leaving in my SIM card, this is just a playing safe method for now).

1. Install TWRP (I trust you all are okay with everything up to this part)
2. In TWRP, swipe right and go into menu.
3. Wipe / Format Data / Yes
4. Reboot into RECOVERY
5. Flash DM-Verity
6. Wipe / Factory reset (by swiping)
7. Flash Renovate - I chose to root with Magisk cause it works for my banking apps.
8. After flashing Renovate, allow it to boot into System.
9. Do your basic setup and then reboot.
10. Now insert SIM and continue to setup your phone, Ti and all that good stuff. Phone is now rooted and working, TWRP is all working and safe to use as normal. This is the part that I did Ti restore and flashed Viper4Android etc etc.
11. Happy days for now, until we work out exactly what the issues are.......

The only thing I did not do was to try and flash the XSA firmware (Australia Unbranded) with the S8 CSC firmware installer. Apparently another user used it and it worked for them on the Note 8, however I did not want to chance it for now. The only drawback is on Volte and WiFi calling is missing but that's not a deal breaker. I might research a bit more before I try to flash the CSCSelection_S7_S8 zip.

I was in the same boat as you - if Renovate floats your boat then check out my last post, I've installed Renovate and all working nicely again... Waiting for one week then in jail for another week sucked hard!

Great to hear it worked for you. I was thinking of using Renovate as well as it looks like the best option we have at the moment. Now you have confirmed it's all good I'll be doing it the day I'm released from OEM jail. When I flashed stock firmware I tried the note 8 xsa to see if it was any better than the Telstra version but instead just lost features and gained new things in settings which didn't even work so went back and flashed Telstra version.
I know it's wishful thinking but does Samsung pass work for you? I don't care for Samsung pay and health but Samsung pass was a nice feature.

Just tested that out for you, unfortunately that is the only one that does not work (Well we know Samsung Pay won't work due to KNOX being tripped). It goes through all the setup okay, then on final authentication it says "Samsung Pass is temporarily unavailable, please try again later". So that's a bit of a bummer.. I've tested Android Pay, all good, and I also use NAB pay and works with no issues as well as long as you set it up correctly with Magisk (there is a bit of a method to follow but I found a way to make it work - in case your with NAB at all).

I might make a suggestion to mwilky to see if that could possibly be fixed in the ROM as I agree it's a great feature.

Edit - That question was already asked by another user, mwilky says that it does not work the moment TWRP is flashed and not likely able to be changed. Bummer.
