REMINDER: OEM Unlock - Samsung Galaxy A8 (2018) Guides, News, & Discussio

Just a quick reminder to NEVER EVER and I mean NEVER EVER turn this off if you have TWRP and Root on your A8 device or else it will soft brick your phone.
"Custom Binary Blocked by FRP lock" when trying to turn on but it won't.
Learned that the HARD way. My hour and hours of customization, GONE!
Flashing ODIN by stock will solved it

[Q] need help with note 3 re-rooting

I successfully rooted my Note 3 (tmobile) and tried several roms over the past few weeks. The problem I now have started with the last one i tried. I inadvertently mistook a rom for one that was stock and it unrooted it, adding knox back and undid all my hard work.
I started over and for some reason when I retraced my steps, the phone will only go into download mode and when it reboots, the boot screen comes on and then turns back off. I've used ODIN 3.09 with CF-Auto-Root, and tried the De la Vega root, and it all does the same thing. Sometimes I get the red android screen that makes it seem like it is rooted, but when it reboots "after 10 seconds", the screen goes black and never turns back on. I'd be happy with starting over again and trying from scratch, unless there is another way. If anyone could help me I would be eternally grateful.
I'm willing to do anything, whatever it takes, if anyone has the guidance and insight on what is going on here.
Thanks,
Karma

Unfortunately I cannot help you. Just subscribing for info, knowledge is power and I am preparing to root and ROM my new Note 3. Best of luck with your dilemma.
What did you flash that you believe caused this ?
ok so here's the method that i always have used to gain root.
It's very simple and effective.
keep in mind this will trip your knox to 0x1 if you even care!
all you have to do is download the latest twrp or philz recovery (I recommend twrp - available in the tmo n3 original development section) and flash the .img.tar file in odin.
that will give you a custom recovery.
Then what you need to do is download the latest supersu.zip file and place it on your sd card or just dl it right on your phone.
then reboot to recovery (power off device and simultaneously hold the volume up, home button and power button.) you will see in blue font in the top left of the screen "recovery booting".
then in twrp flash the supersu.zip
bam you have root!!!
remember to read and search if you plan on any future flashing to be safe!
I recommend you flash a clean stock NE6 with ODIN. Then, you can root with Towelroot with just one click. It's that simple. It's worked for me when I lost root trying to update to latest build. Then you can upgrade using Mobile Odin Pro and using the "inject" root feature.

Breaks enterprise security. If you need it for work triggering knox breaks it and is unreversible. Its also permanently flags the device warranty as voided.

OEM unlock not showing for the second time, RMM state prenormal again

I have a G960F/DS, I tried to root after the 7 days waiting so when I had the option I enabled OEM unlock, BUT it asked me to do a factory reset so I did, but I didn't know that I should have to enter download mode before rebooting, so now I have OEM lock and FRP on OFF, but I've got the RMM state again in prenormal. I waited again 7 more days but the OEM unlock option is not showing again, what should I do? Wait more time? Do another factory reset? Install again the stock rom?
That's weird. Maybe re-flash stock firmware, wait 7 days. When enabling OEM unlock and it requests to factory reset, once it reboots go straight into download mode and flash TWRP. From there in my experience OEM unlock will always then be there, even when I did re-flash stock ROM at a later date.

When you first had the OEM unlock, did you ODIN install TWRP and then flash the NoVerify file immediately after doing the Factory reset. I waited the 7 days, did the above and OEM unlock always shows up now in developer options even after trying other ROMs and just going back to stock rooted setup.

Any ideas?
I'm pretty sure everything I just read there was wrong... W. R. O. N. G.
Firstly.. If you're unlucky enough to have a phone that's going to have the RMM state.. It's a 2 week wait MINIMUM.
When you first get the phone, select the OEM unlock and be prepared for it to reset the phone and reboot... This is NOT OPTIONAL... And at this point if you see the RMM state as PRENORMAL you can forget about flashing twrp or anything else for at least another 7 days.
Anybody that tells you that you should have flashed twrp before you restarted the phone doesn't know what they are talking about.. When you press that OEM unlock button for the first time.. That bloody phone WILL REBOOT, It WILL RESET... There is no way to get to ODIN MODE and even if there was, the RMM state is triggered straight away if you have one of those phone.
I have an S9 that had no RMM state period.. I was able to to flash twrp straight away.
I also have an S9+ where the RMM state was triggered the moment you accept the phones request to restart after selecting the OEM unlock.
Secondly, after you've selected OEM unlock and the phone has reset and restarted, I'd suggest leaving it on for 7 days... Some people say it doesn't matter if you turn it off, but to be safe.. Just wack it on the charger and leave it.
Once the 7 days is up, the OEM option will reappear... Ignore it.
Boot the phone into ODIN MODE and see if the RMM STATE has vanished.
Understand... It's a 14 day wait... Not a 7 day wait.
Wait 7 days from purchase for oem option.
Unlock oem.. Reboot/reset phone.
Wait 7 more days for oem option to reappear.. Ignore it and boot into Odin mode.
Flash TWRP... For the love of God turn off the Auto restart in Odin.
Prepractice the art of restarting the phone into TWRP manually.. If you miss your window of opportunity and it restarts into android one of two things will happen.
Best case scenario.. You have to reflash TWRP.
Worst case scenario.. The RMM state comes back for another 7 days.
To get out of download mode
Hold volume down and power for 7 seconds.
The moment you feel the phone vibrate (a fraction of a second before the Samsung logo appears) boot into TWRP by
Quickly releasing all the buttons then very quickly press the power, up volume and bixby... And you need to do it BEFORE the screen initialises.. If you see the Samsung logo and you haven't got those buttons down.. You've missed it.
Make sure you have all your files ready to go... With this phone being so *****y I had all my files on both the sd card and a usb with OTG.

I have done that, activated oem unlock, it asked to do a factory reset so I did, got rmm state prenormal again, then waited 7 days again but still no oem unlock switch for the second time, now I've tried the method that involves changing date and checking for new updates without results, now yesterday I've re installed firmware, bl, modem and CSC, factory new, and still no oem switch, still prenormal
Ok, I went through the same thing determined to find a way around the 14 day wait period... That included downloading 9 different Samsung firmwares from Sammobile all different versions from different counties.. It didn't work, and each time I installed a new firmware it reset the 7 day RMM state counter... I lost 3 days trying that on the S9+.
After the first OEM unlock /reboot /reset did you just leave it on, not touch it except to check the uptime in the settings... I know other people said you can turn it off, but I've been through this on an S8+ and s9+ and it definitely worked better just leaving it on and making sure it got charged occasionally.
I can tell you now, installing that new firmware just reset the RMM state back to 7 days.

I mean some people cant wait and reboot into ODIN mode to check before the time is up... Did you wait the full 168 hours.

The first time, before ticking oem unlock switch, I even turned it off some times and checked download mode to see rmm state, even after that I got the oem unlock switch after 7 days, then I switched it and now I got oem unlocked but rmm state prenormal again, but I have waited 7 days again with no results, yesterday I reinstalled firmware, CSC and everything, guess I need to wait 7 more days without turning it off.
Could it be that I bought my phone from ebay and my service provider and CSC are AFG (Afganistan)? But my phone is unlocked, I use it in Mexico

My phone is SAME as yours except I use Tmobile in US. My phone is an S9. Unlocked from a third party Net I purchased from as new and it has the same AFG CSC. I waited exactly 7 days. But installed TRWP immediately by holding Pwr Vol dwn and Bixby from the Format data answer yes etc after seeing the OEM unlock after that 7 days. This was my experience all I can say.

So did you not format the data and just reboot into the bootloader after clicking OEM unlock?

When you toggle OEM unlock it will ask to reboot. At that point power down the phone, DO NOT REBOOT IT. Then hold volume down, bixby and power to get into the bootloader. Once there, you will see your RMM state is NORMAL. Now confirm by pressing volume up or whatever it was and you will be able to flash TWRP with ODIN.
This is where it gets tricky. Once the flash is complete the phone will reboot. You will need to hold volume up, bixby, and power for about 5 seconds to boot directly into TWRP. Once there you will need to wipe, then reboot recovery and flash no-verity, then reboot and flash RMM fix.
If you don't follow above, and the phone reboots you are screwed into waiting another 7 days if your lucky, otherwise you will need to flash stock firmware again and the whole process starts over.

This has got to be the most concise write up of the situation. Thank you for clearing it up!
I've been RMM Prenormal with OEM unlocked for about 10 days now; no new firmware or wipes or anything, just waiting it out. I have no idea when it will be back to Normal; should I wipe it to reset the counter to wait the 7 full days anew, or should I just continue to wait, checking the recovery every day until it is Normal?
There is only one thing I can say... THANKS a lot, Samsung... This was my last SAMSUNG phone !

I face the same problem. 7 days are not sufficient on my phone. Have been waiting 169 hors and do NOT see the OEM unlock at all. So will have to wait 7 more days... I doubt it will then appear
Then I have to reboot to odin-mode, see the RMM state and reboot and wait againe 7 (or maybe 14 ??) days ???
GREAT feature from Samsung...
If it is not possible to root the phone, I will sell it and never again buy anything from Samsung..
after the 7 days or 168 hrs, just reboot and check again on dev settings. That worked for me.

Could somebody clarify?
Sure, I'll clarify in about 1 week when my Note 9 512 gig phone arrives.
I'll try his way first, however what I stated about being ready is vitally important.
Make sure you have everything you need on an SDCARD AND on a USB stick if you have an OTG adapter.
You can't put any of it internally on the phone because to remove the encryption you need to wipe the internal storage completely.
So make sure you have
no-verity-opt-encrypt-6.0-star.zip
RMM STATE BYPASS
A selection of custom firmwares.. Alexandr's excellent devbased roms have RMM STATE BYPASS built in, they also have Xposed built in by renaming the rom slightly such as N960Fxxx_DevBase_v6.x_xposed.zip
Will install Xposed framework.
Renaming the rom as N960Fxxx_DevBase_v6.x_noroot.zip
Will install the rom without root or Magisk being installed.
I use his rom on both an S9 and an S9+ and they work perfectly.
So read and read and read, and when you've collected everything you need on two different media.... READ SOME MORE.
I'll update this thread when I try out shiftr182 method.
Most importantly, before you do anything.. Practice booting into recovery and Odin mode till you get it down pat.. You really only get one go at it.
Now mind you, I'm really cavalier, I'm a computer technician and I can't sit around wringing my hands together worrying about what's going to happen or I'll never get anything done, so to do this you do your homework, lots of homework and then you take your balls in your hand and do it and accept that if it all goes arse up... Well you tried.
It's actually pretty hard to totally brick these phones.. It just means more waiting, more reading and more asking questions.
I hope this has not only qualmed (not the urban dictionary meaning) your fears but also put the fear of God in you.
DO YOUR RESEARCH :angel:

A word of advice for folks who unlocked the bootloader without doing a factory reset

Yeah hey y'know how the usual default for accessing the bootloader menu in phones is like, Vol. Up+Power or something like that? Yeah, don't do that on the Mi A2 Lite. It'll factory reset the phone.
Signed a dumbass who now has to set up their phone a third time this month (first time was intentional, second time was a f*** up trying to get Camera2 APIs working.) xx

There's a thread about unlocking the bootloader without losing data. I'd you do that, some flag is left behind and getting to stock recovery does a factory reset.
But yeah... Generally not something you'd expect to happen automatically and silently.
Click to expand...
Click to collapse
So ignoring my anger driven original post, it turns out that if you forcefully deny the phone a factory reset when you unlock the bootloader (to enable Camera2 APIs, for example, as I did), then do make sure to not hold Vol. Up+Power otherwise it'll end up going straight to that factory reset it originally wanted to do back when you unlocked that bad boy. Considering it happened to me first hand, I'd recommend NOT giving it a try yourself to see if it's actually the case unless you don't care about whats on your A2 Lite.
Vol down + power = fastboot (bootloader)
Vol up + power = recovery
The stock recovery doesn't really do much but it is involved in factory reset (either explicitly called or when unlocking bootloader).
I have started the stock recovery but it didn't do anything (I think a "script" on data is used to tell it what to do).
Okay but generally speaking stock recovery's shouldn't automatically factory reset the phone without prompt? No stock recovery I've ever seen has done that
Also I just realized in my anger driven stupor that this was accidentally posted in the ROMs section lmao sorry mods

Flashing firmware while samsung account still present?

Hi, is it possible to flash a new firmware of this device while the samsung account still present on the device?
Can anyone tell me what would happen if i would simply flash a new firmware and root it without logging out the samsung account beforehand?

I'm not sure exactly what you're asking. If you dirty flash firmware (no data wipe) and root it, then you'd be updated with root and still have all your credentials on the device.

Sorry for not clarifying. What I meant is to simply flash a new firmware with odin while the samsung account still in the phone, as in, if we want to do a factory data reset from the settings interface, we have to key in the password or unbind the device from the account

Are you asking whether flashing factory firmware will get rid of FRP?
I typically use Odin to flash firmware, and there's two ways to do it. In the firmware package, you have the BL, AP, CP, CSC, and HOME_CSC files. If you want to dirty flash without wiping user data (including a Samsung account), use the HOME_CSC file in the CSC slot. If however you want to force a data wipe, use the CSC file.

Erm... I don't know what an FRP really is, it has been a while since I last do phone rooting and flashing
I am asking because I saw a warning of odin v3.14.4 with the following message

Did you have a Samsung account on the device already?
FRP = Factory Reset Protection. Requires the Google account login information that was previously on the device before factory reset in order to continue setup; this is an anti-theft measure.
Your bootloader has to be unlocked to use Odin.

Yeah, you could say get rid of FRP
It has the account of the previous owner (it was given out). The previous owner kept telling me to bring it to a samsung center to reformat/factory reset it because the previous owner forgot his password
By unlocked, did you mean from the developer menu?

That's where you start - you enable OEM Unlocking in Developer Options, then you reboot to download mode and unlock the bootloader.
A clear indication of whether the bootloader is unlocked is the "OEM LOCK" line in download mode; if the bootloader is locked it'll say ON, if unlocked it'll say OFF
Are you able to get into the device at all? Is it locked by a password or pattern? If I were you I'd try to get the previous owner to unlock it; it's their responsibility to remove FRP before they sell the device.

I don't know how to get into download mode and unlock the bootloader. From what I've read, I need to turn off the phone, press power/bixby? + volup then plug usb? This is the actual part that I somewhat confused because I already have the required file in order to root, twrp, and ketan's rom. Just the instruction wasn't very clear on what exactly what I must do, more below
Yes I'm able to get into the device, it is just that I can't get rid of the samsung account of the previous owner that enforces the FRP from the settings page because the device asks for the password of the previous owner's account in order to remove it
The flashing/rooting instruction were from http://www.mediafire.com/folder/d4ugie4yadxu6/N975F which is:
Section 2
Instructions for users who are on Stock Q/R/S Non rooted/Other ROMS or running trouble like boootloop
- First install stock latest stock S (A12) firmware (recommended same base if available, base info can be found in changelog post on XDA)
- Download ROM N975F_N976B_DrKetanROM_S*.zip and copy to SD card/USB & Check MD5
- Download & Extract N97*_TWRP_*_tar.md5 + Booloader and Modem according your device variant.
- Flash TWRP file with AP tab of Odin
- Again Reboot to Download mode
- Flash Bootloader and Modem
- Reboot to TWRP(DON't REBOOT TO SYSTEM) - Wipe - Format DATA (Full wipe) This will erase all data from your device
- Reboot TWRP - Flash N975F_N976B_DrKetanROM_S*.zip
- Reboot to System
Read Instrcutiona at end "After rebooting to System"

The part where I don't get is, "again reboot to download mode" and "reboot to twrp". I read on other thread, I have to untick "auto-reboot" option in odin?

No, don't press power. Just turn phone off, don't connect USB yet, and hold both Volume buttons while plugging in USB cable. It should start with a prompt for download mode, device unlocking, or cancel. Select device unlocking.

Yes. The idea here is that after you flash TWRP, you can't let the device boot into system, because if it does, it'll overwrite TWRP with the stock recovery.
But let's just focus on one step at a time; you first need to unlock the bootloader. Use the key combo I described above, and select whatever option mentions device unlocking. Should be a blue warning screen asking if you want to unlock the bootloader (may have an option for Device Unlock mode). Follow the prompt to unlock the bootloader. Once done report back here and we'll go to the next step.

I followed your instruction, I wasn't sure connect to which, a charger outlet or pc/laptop. I decided to connect to a laptop anyway while holding both volume buttons. As you described, a cyan warning screen appeared, I proceeded by holding volup and another volup again to proceed with unlocking bootloader. It states that the phone will be wiped during the process.
The phone rebooted twice, first one says there's a yellow triangle that the bootloader has been unlocked, it shows the android with "preparing" message. It then rebooted once again and I pressed the power button to proceed when there yellow triangle appeared on this second boot up.
The phone stuck at SAMSUNG text for like about 5 minutes? I thought it got bricked or something so I detached the usb. After a while the phone booted up like a new phone with the first time setup wizard. I skipped everything.
Going into settings, the account of the previous owner is not there anymore, checking software information shows the latest build of N975FXXS8HVJ1, oneui 4.1, android 12

Alright, success. So what is your end goal here? Are you trying to install a custom ROM? Let me know what you're ultimately trying to accomplish so I can help you with the next steps.

Thank you for the help.
I actually came from samsung galaxy note 1, gt-n7000, hard bricked accidentally 2 years ago because of the brickbug present if I'm not careful, but it got me. So I am using a vivo phone for almost a year, for which I can't even flash any firmware let alone running adb commands to grant permission on the phone. It is running android one and it has full locked down in my opinion.
I actually missed the viper4android that I tweaked on my note 1 for a very good sound quality I achieved back then although viper4android wasn't the only reason I wanted to root it. I would like to have adaway at least as well. Perhaps some other 'extra' features that stock can't offer.
I'm not sure how do I put it during the use of this device while still in the previous owner's account is that, when I launched netflix or youtube (respecting the privacy of course), the phone screen became brighter than I would like. Even if it is slightly dimmed, launching one of these app would make it brighter, then go back down to previous brightness when exiting them.
There's already a screen burn-in from excessive youtubing from the previous owner and I can see why, 3 years later this phone has burn-in already because of the app's behavior of 'boosting' the brightness. Not sure if some of the rooted modules 'can' prevent these brightness adjustments by the app or not.
I also never used any banking/financial app on any of my mobile devices
edit:
I often go for stock rom most of the time.
Coming from note 1 that has the potential brick bug during that era especially exynos variants, this note 10+ don't have any potential brick bug do they?
I also tried to restart the phone, I still get that yellow triangle warning saying bootloader has been unlocked and can't be verified, would like to get rid of that as well. Furthermore, I checked the developer menu, "oem unlocking" is now missing
You didn't answer my question, bud. What are you trying to do? What is your goal? For example, are you trying to get a custom ROM installed? Or were you just trying to get the Samsung account removed?

OEM Unlock Doesn't Exist | Galaxy Note 10+

Hey guys I have finally admitted defeat, Im not really sure what else to do at this point, as I have tried a lot;
- Flashed the base android pie (12.0) OS
- Hard reset
- Changed Date and Time back 7 days to prevent jail
- Disabled automatic system updates
- Disabled things such as updates, timezone change, etc.
Enable Developer options: and OEM doesn't appear at all, simply doesnt exist, not even grayed out or anything
The only thing I could find online explaining this issue is that the reason this happens is because my device is SIM-locked. Which it isn't. It's fully unlocked (XAG/XAG/XAA)
Model: SM-N975U1 Region: XAA
Any help would be great thanks
and yes it is connected to the wifi, and tried updating also (im on the latest), still nothing has changed

Your device is probably RMM locked. Please take a look at this thread.

I don't quite understand this part;
"
When Odin shows "PASS", take your device in hands, disconnect the usb cable and press simultaneously the "Power" + "Vol. Down" + "Vol. Up" buttons until the downoad mode disappears
At the precise moment the screen becomes black, immediately release the "Vol.Down" button and press the "Vol. Up" + "Power" buttons during 10 to 15sec to forcefully enter TWRP
***Don't boot into rom because it will lock your device again!!!!
Once the custom recovery booted, swipe to "Allow modification" and flash RMM-State_Bypass.zip as normal zip"
I flashed then did as it said but it just sends back to the original recovery screen

RMM locking prevents flashing AFAIK. Please check for "RMM state" in download mode, if it's "Prenormal" then you're locked out.

Wait isn't RMM state just that 7 day jailing? I tried doing this before I flashed/hard reset my phone was on months before I reset it and was still unable to get that OEM option

I understand the lingo a bit more now after reading up, but that article is a flat circle. It wants me to Install twrp to flash a RMM bypass zip (which you need to disable bootloader to even do in the first place), and you need root access to use twrp.
Yet the information provided below of how to root tells me I need to install twrp and boot into it's recovery, but you need to be root to do that?!?
Make it make sense!
Probably by flashing a combination without etoken or something of that sort?
Locked bootloader prevents booting unsigned boot stages.
What about disable Knox through ADB with the SamFwTool ?
I think you may need to remove google account and screenlocks first, not sure.

Disabling Knox within SamFw works, however I am still KG/RMM locked
Hit a brick road here not really sure where else to go...
I have a Galaxy Note 10+ (SM-N975U1 XAG) that is RMM locked an unable to get the OEM option in dev settings,
Since Knox is one responsible for the valutmanager line that releases the RMM check, I tried disabling Knox completely through SamFW tool, disabling works, however I am still locked.
Any help would be apricated...

Thanks,
First option I can't do TWRP since I need root and unlocked bootloader, so next step;
Miracle Box Thunder ive been messing around with before, is interesting, can only get it to work for the first half second it connects to my phone and then the stop button grays out :/
Though I got it do to this for the "Reset Reactivation/EE Locks":
Start Detect device.
Device detected OK.
Downloading..
Get phone data..
Reactivation Lock Reset Launched...
Searching For Reactivation Data 1...
Loading Data Please wait..
Rc Block Update ok...
Processing Data...
Done..
EE Lock Reset Launched...
Searching For EE Data 1...

>>All Done..
I am unable to view my download mode info in the top left. Would you know how to "enable" it or how I can go about viewing it another way?

Actually while doing the "Reset Reactivation/EE Locks" it gave me a text top left of the download mode, saying "ODIN: TOKEN Size is too large [-13]"
Update...I was able to bypass the RMM/KG lock by first doing a fresh install;
skip through all intro and setup (or just FRP skip)
DONT SET A SCREEN LOCK, must be unlocked or swipe otherwise you will be softbricked in a infinite "starting device..."
next you use Minimal ADB and Fastboot terminal and type "adb shell pm disable-user --user 0 com.android.systemui"
your phone is gonna freak out now dont worry about it and open up FRP Samsung by NKTEAM and click "Kill update" (this is important)
then after kill update is complete you can run "Disabled KG Locked MTK ADB" which will lock your phone saying you uninstalled a samsung service etc....just reboot your device and your good!
Though, I don't understand how to unlock OEM still? I still don't have the option?
Should I flash oreo or something? Though flashing causes it all to relock again
Not to give up and never admit defeat, here is what I would do since I am not sure what that RMM is, I am not actively reversing this technology just collecting information from the web.
I would ask the tools creators through their support chats if they can extend the tools to deal with the faulting security mechanisms. At the same time I will check where is a cheap replacement board, just in case help it brick itself (yes the security mechanism design is self-destructing, I do not admit I break it it breaks itself).
I will flash with Odin with pit file with format to try to truly revert to factory. If I am not happy with the result I start becoming creative with the tools at hand LOL:
Then I will start flashing Bin-compatible official files with patched Odin, until the device resets itself to factory at least two times. The idea being due to crypto differences in the versions, the entire partitions gets rewritten during flashing. I would try this by removing all locks and protections (accounts), resetting to defaults, and flashing the first and the last bin-compatible firmware from samfw site.
Someone mentioned they achieved not-keeping previous things by mixing their firmware files AP BL CSC etc this is something I would try to try and get the device to confuse the crypto and overwrite things.
The idea is that the second stage bootloader BL will always be able to get you to download mode to flash with Odin so messing and even triggering with the later boot and protection stages should not erase the XBL. If it does then I will need the emergency_download_debug whatever package for the Bin version.
What Bin version is the device anyway ?
SM-N975U1 is Snapdragon. Why did you think it was Exynos?
Ask @afaneh92 he is unlocking specific versions of bootloaders for US/Canada devices since the SamPWN team are missing from the forums. https://forum.xda-developers.com/t/...unlock-for-samsung-us-canada-devices.4215101/
