Going back to Oem bootloader lock? - Samsung Galaxy Note 9 Questions & Answers

Hello,
I have the SM-N960F/DS phone who is presently Oem unlocked. Unfortunately, Google safety net fails with CTS profile mismatch because of this, and thus I can't use google pay.
If i turn Off Oem locked, what will be the consequence? I guess the device will get formatted, but is there any thing i should be aware about?
Thanks

In my case with my old Note 8 ( also my old Note 5 )
i was not rooted and i switched OEM unlock, on and off
(2 or 3 times over a period of time).
Nothing really "happened" My device was not "formatted" /factory reset. etc.
Further, i also noticed, that when i unlocked OEM, my Google Play store, had shown
in Play store settings, Play Protect Certification "device not certified"
However when i locked OEM, a day or so later, it showed "device certified"
(See example screenshot)
Good luck

Thanks. I did an OEM unlocked on my non-rooted phone and the device got formatted. Also, it now passes the safety net.

I have just spent a lot of time with my SM-N960F Anroid 10 'Q' and I have some input because others have found the date shift trick doesn't always work for them and it didn't work for me.
If you get part way through a TWRP reflash and root you will have broken the KNOX security. You can NEVER get it back, which is o.k if you accept what you lose and the benefits of TWRP, Root access, flashing a custom ROM without bloatware and lost warranty. You will save money on phone pay to.
You can download an App to test if KNOX is present or broken. When you power the phone you will either see the OEM Unlocking option missing or it's grayed out with the message saying it's unlocked. If it's grayed out your Note 9 is still useless because ODIN won't accept anything but genuine OE files. FASTBOOT seems unavailable too.
O.K so you flash back the OE firmware and the phone boots o.k but there's no OEM Unlocking option and ODIN still won't accept a non OE flash image like TWRP. You try the clock back tricks and it still doesn't appear. The time initially comes from the firmware file if the phone has been reset to factory defaults after reflash. If you change the phone time and turn it off, it boots back to the firmware date not that date -7 days.
To avoid downloads & updates I always reflash without a phone network SIM (no downloads via network) and with no wifi credentials. This is the problem and could explain why some can't get this to work and others (who still have active wifi or data over network) can.
Having done all the tricks to set the date back leaving it in manual and stopping automatic updates, I re-entered my wifi credentials. Within seconds there was a beep, the date updated (even in manual mode!) and the OEM boot option appeared unlocked in Developer options. Note: You will never get this come up with 'OEM bootloader locked' once KNOX is broken. Went on to ODIN and it now accepts the non-OE TWRP image and anything else.
Conclusion: There has to be a data connection when the phone either gets updated date 7 days later than the date you set from a time server, or gets something back from another (Samsung?) server to restore the missing OEM Bootloader option?? You don't have to wait 7 days either. The problem for many going through reflash is if they never saw OEM unlocked in Developer options they would't know it should be there and will give up sticking the OE firmware back when the missing entry will eventually come back 7 days later. I think after this I'll go back to my Nokia 3310.
I'm still curious as to why I get comms with adb but not FASTBOOT. Which only leaves ODIN as the flash tool for this phone.

[Q] Not registered in Network => Return to Vodafone?

Dear all,
I just want to make sure that my vodafone LTE S3 GT-I9305 is ready to be given back to vodafone shop (sim card is not recognized at all, either some kind of lock or simply broken). also got message "not registred in network". vodafone employer came to us in store showing us the s3 saying "just want to show you the color". now i figured out that the box was already open when he came to us....
got phone yesterday but never tested phone function before rooting. used CF root with CWM and later also CF auto root to get back stock recovery. also resetted flash count. never flashed anything else, especially no other image. just did these two root options.
my questions:
- after final root with CF auto root I used Triangle Remove and Downloader showed count of zero, binary "Samsung Original" and system "Samsung Original". But after resetting phone (wipe in recovery console) it shows system in downloader "custom" (binary is still samsung...flash count still zero "no"). Is this normal?
- is recovery console the original one?
- am i good enough to go back to vodafone with this?
more info

Some more information, because I saw some post on other poeple having same problem with "Not registered in network"
Maybe it is some issue, because phone might have been unlocked before I bought it or imported from somewhere. You never know what those guys in vodafone shops really sell to customers....Or it might be locked although it should not be locked. As I said before...Only rooted phone, but never flashed any other image or radio version. Basically only thing that was changed was to put on CWM after first root....and using CF Auto root to get back stock recovery...
MORE OVER==== IN SETTINGS IN STATUES it says=
network=not know
service state=out of service
roaming=not roaming
ERI version =not available
mobile network state =disconnected
serial no=it is shown (but i will not post it here)
imei=Not known
device status= Customized (in German "Geändert")
Might have lost IMEI....also tried *#06#....show "null/null"...
why does it say System Status : Cusrom And werent you the person who sister tried to root it and you didnt know what root she used because now ther is not any imei showing?

[GUIDE] [fixed] SIM UNLOCK after lollipop

this thread is just for lollipop 5.x m7wls (sprint) based on sense roms
no need to S-OFF
if you are on kitkat or less here or here if you are on the stock ODEX rom
1 - you need just to unlock bootloader from htcdev.com
2 - TWRP or any other here is the TWRP for m7wls(sprint)
3 - flash SuperSU
4 - its time to flash HtcOMADM_SPCS
5 - install sim unlock helper.apk
6 - Insert your SIM card, you may see this massage No Network Found
Code:
Select "YES" to switch to global mode
Select "NO" to stay in the current mode
but do not worry since your phone dose not say invalid sim card . so now go to setting , mobile data . and chose GSM/UMTS only. tell now you wont see any signal , just scroll down to Available GSM netowrks ,then Search networks you will see a list of networks and only one that is available, chose it .
now if you want to stop the annoying vDM crash massage flash the stock-HtcOMADM_SPCS .
Its better to relock your bootloader and flash the RUU rom so every thing works well and you wont see the No Network massage again .
That's it ^_*
it really works but, it didn´t solve my problem i guess my problem is not sim unlock i can not have signal for gsm it stuck in CDMA but in *#*#4636#*#* it shows up like radio turned off i want to turning on but i can not,:crying:
anyway thanks:good::good:
I've tried your guide and elvisypi's guide, but neither work. I'm using a rooted M7, lollipop, stock ROM.
When using the SIM Unlock Helper app, I get "OS Check Fail! You aren't running HTC Sense!", but if I hit the back button I end up at a screen that states "Device verified, root available, sense rom (yes)". Hitting Start does open up the menu, but never before a vDM client crash. After hitting Sim Unlock and it hanging for a few seconds, the log is empty after hitting back to return to the unlock helper. The screen says "Log empty, did you run the program first?"
It seems to me that "vDM" is what is supposed to be doing the work, and it's crashing so it can't...
when OS Check Fail! appears to you press Display SIM Unlock Log then go back and press start and scroll down to sim lock
if that menu did not appear to you try flashing this instead

Not unlocking
Hi I am have bootloader unlocked, intalled TWRP, and rooted. Tried with Stock Sprint Lollipop ROM and menu would not pop up. Flashed to Viperone 8.0 and I am able to bring up the menu. Once Sim Lock unhighlights I hit the back button and get the SIM unlocked successful message. The reboot in that screen does not work for me so have to hold power button down and reboot. I have changed settings to GSM and WCMDA preferred. Next pop in an ATT SIM and a Cricket but still get invalid SIM. Any ideas? Also, I am S-On as I have been unable to off with HBoot 1.61
Hi, I bought a Sprint HTC One M7 (running 5.0.2) from someone figuring that I'd be able to unlock for use on Verizon (because every phone can be unlocked...... right? ). I first unlocked the bootloader with HTCDev, ok good. Then I ordered a SIM unlock code off the interwebs thinking that I could just go get a Verizon SIM from them and then enter the code when prompted. Took the phone to Verizon and they couldn't help, said that IMEI was not valid and they couldn't give me a new SIM because the current phone I have (Incredible 2) isn't eligible for a SIM only upgrade, then they said I should just purchase an upgrade with the EDGE plan (yeah right). I then used the SIM card of a friend who has an M7 on Verizon hoping that I'd be prompted for the SIM unlock code then, but I only got "invalid SIM......"
So, I stumbled upon this thread and followed the procedure to flash TWRP, then SuperSU, confirmed that I'm rooted, and then flashed HtcOMADM_SPCS_2.zip, and ran SIM unlock helper. I got the same error as the other guy "OS Check Fail" and vDM client crashed, but then I press back and go through the SIM lock part and reboot. So now I can put my friend's Verizon SIM in and I get no SIM error, but I am still not prompted to input the unlock code for my IMEI. Any Ideas, or is it not even possible to use a Sprint M7 on Verizon?
EDIT: I am now S-off with sunshine (hboot 1.61)
EDIT 2: Ok, now I'm getting to a point where I put my friend's SIM in and it prompts "preparing SIM", "SIM card inserted, tap to complete setup". Once I tap the notification, I get taken to a screen that says select your carrier. It takes a little while to load the carriers but Verizon appears, but after I select verizon, the page disappears and nothing further happens. It then repeats the loop from "preparing SIM".
EDIT 3: From TWRP I wiped all data including the OS. Then I got stuck at the splash screen, reflashed [STOCK ROM] [5.0.2] [SENSE 6] Sprint 6.16.651.2 rooted from phonegeekjr (PhoeniROM ?)

I think You need to change the CDMA via DFS so it can be recognized by SIM card
Why
Sprint always use the CDMA as PRL that you can write it via DFS while Verizon use this type of network as a SIM card so that after using sim unlock helper your phone dose not say "invalid SIM" but it didnt show the network signal
As far as I know, the Sprint and Verizon M7s have custom radios operating at their carrier frequencies. Sprint's frequency band is not the same as Verizon's, and even after unlocking, the radio can only scan within its band. Your radio simply can't see Verizon's tower. It seems like your process completely worked, though.
I haven't gotten the chance to try again, but I am planning to eventually.
Also, it is possible to S-OFF through any other method than Sunshine? It'd be nice not to have to pay for that... Is S-OFF absolutely required to SIM unlock/ flash custom roms/ change files at the root level?
This does NOT work...
I think it is pretty obvious that THIS METHOD DOES NOT WORK...
I basically ran the latest RUU - Sprint Stock ROM which put my phone to Lollipop 5.0.2 - Sense 6.0, HBOOT 1.61, S-ON
I unlocked bootloader with HTC DEV, installed the latest TWRP, and rooted the phone, so it is all LATEST and GREATEST as of this post date...
I ran BOTH of the HtcOMADM_SPCS_2 files - both OLD and NEW - and neither one works. NEW is actually worse because the vDM client crashes each time you even try to launch the SIM UNLOCK HELPER app.
With the OLD file you can get to the menu and you can click on SIM LOCK, but nothing gets written to the log before or after reboot, plus when you go to *#*#4636#*#* you can select the connection type, since it is set to CDMA but every time I change it to - GSM only - it will reset to CDMA only when I go back in. So the change refuses to save and I keep getting that prompt saying:
No Network Found
Select "YES" to switch to global mode
Select "NO" to stay in the current mode
So it seems to want to force you back to CDMA mode.
If we are supposed to be running a CUSTOM ROM then please say so, but I am testing with the STOCK ROM and it seems others are NOT having any luck.
So if someone has it working then just let us know WHICH ROM you are using and which files you are using, because it sounds like we are being asked to QA the hack...
Moving on to another solution now...
:crying:
P.S.
Why is someone posting about a VERIZON phone in the Sprint section, kick them out because they add to the confusion...
Wow! OP was edited with a fix 4 hours after I'd figured it out myself. Just made an account to clarify that you need to downgrade the radio if it's too new. I had a lot of trouble trying to unlock it before figuring that out (and I went through an entire series of downgrading and flashing multiple ROMs until I found it out). Here's a guide I made that worked for me.
Have an unlocked bootloader first with HTCDev like said in OP. There's no need to have S-OFF or downgrade anything except radio.
1. Install TWRP.
2. Flash a lollipop ROM (I used Viper 8.0.0) using TWRP. (You can probably skip steps 2 and 3 if you're already on lollipop.)
3. Once booted, go through first time set up.
4. Restart into TWRP and install SuperSU.
5. Reboot and flash the radio (1.00.20.0315_1.29.651.7.zip from elvisypi's thread) and then flash HtcOMADM_SPCS.zip (I used the 4.3 version from chas123) using TWRP.
7. Reboot into System and install the com.viper.simunlockhelperfree.apk (Below; couldn't find where I got it from) then go to display log, press back, press start, then scroll down and press simlock. You could probably also do this using the Terminal method.
8. Wait a few seconds until it unfreezes and reboot.
9. Once rebooted, plug in your sim and go to the phone dial and put in *#*#4636#*#*. Go to Phone Information and set the network to WDCMA preferred. (It might spam you with "No Network Found," so just check do not show again and press No to switching to global mode.)
10. Exit out and open Settings then go to Mobile data and make sure the Network mode is set to GSM/UMTS Only. Scroll down and go to Access point names. (Found steps 10-13 from savage25rcracer while searching through the forums.)
11. In the APNs, choose your carrier and press back.
12. Go to Available GSM networks and press Search Networks.
13. Wait until it finishes and select your carrier.
14. Now you should have service and you are now unlocked on lollipop.
One problem I have is that when data is turned off, it never connects back to data when turned back on and I have to repeat steps 9-13. Any help with that would be appreciated. I did this method with HBoot 1.61 and S-ON and I am using a T-Mobile Sim. Hopefully this works for you guys!
EDIT:
Turns out that switching it to GSM Auto (PRL) made it automatically reconnect for turning data on and off, but data doesn't work after reboot until I repeat step 12.
Check my older post I have a fix for the in an out signal and it reconnects automatically... Thank me later. Spread the word... It's well worth it. I use it.
Sent from my HTC One using XDA Free mobile app
i tried with STOCK & Viper ... not working
with Stock SIMunlockhelper didnt give me MENU after i hit START
with viper it takes about 2 mins freezing when i hit SIMLOCK... then still nohting after reboot Network operator DIMED & alot of times it give me ERROR (vDM Client isn't responding)
NOTE : on lock screen it says (Invalid Card)
It doesn't say invalid sim,i selected ATT from the list of the carriers,i selected GSM/UMTS under mobile settings but my Network Operators Menu is grey and i can't select ATT there.Any ideas.
REVISTED - Did this work?!

Well, it seems this is the ONLY SOLUTION that worked for me, because I tried the Bad Boyz custom ROM that some others have suggested but it does NOT seem to work and there are "bugs" like the status\notification bar disappearing when you start to mess with the ROM. I flashed the Viper 8.0.0 ROM with TWRP and everything loaded properly except for one little "bug", which is this constant non-stop blinking NFC icon in the status bar so I might have to find another ROM. I wish I did not upgrade, so if you have ANY HBOOT under 1.61 - DO NOT UPGRADE WITH OFFICIAL ROM - because once you have 1.61 then you cannot S-OFF although you can downgrade the radio with S-ON and it is just a matter of unlocking the bootloader.
2 Notes:
1. Make sure you install SuperSU and do not rely on the Viper version, so let it uninstall any other SuperSU after installing from the Play Store. I believe the SuperSU installation will fail for you if you install through TWRP, but ViperROM should be rooted and instead install SuperSU from the Play Store if TWRP installation fails.
2. When you run "SIM UNLOCK helper" it WILL FAIL the first time, because you need to have SuperSU give it permission so make sure you go to the LOG in the options. Afterwards, make sure you close everything and remove from latest apps list. Then run again, when it fails then open LOG then hit BACK and now it will show you that you PASSED THE TEST. Then START then scroll down to SIM LOCK and wait like a minute or more because it took a LONG TIME for mine to un-freeze but then I hit REBOOT once it came back which is right there in the same list. If you doubt it, then reboot and do again but I was able to get it to work and then when I changed options in 4636 it would look for my SIM and did not give me any errors.
Anyway, I was able to follow all the steps here and the key seems to be downgrading the radio, because nothing seemed to work until I downgraded the radio version and then I tested it with both an AT&T and T-Mobile chip that I have lying around. The T-Mobile chips seem to work with no problems as others have noted, so you are able to make changes, register on the network, and set it up but I had problems with AT&T although I got farther than with any other modification. The AT&T chip will let you select the AT&T network, but you will not be able to scan for networks and you get NO BARS although it seems to be connecting or doing something although I suspect AT&T or something in the software is blocking you from connecting 100%.
So I cannot say 100% this SIM UNLOCK worked, but at least I was able to get to options that I could not get to before and I tried BOTH chips and only the T-Mobile chip seemed to work without any problems, so I suspect what others have reported is true and the Sprint HTC ONE M7 seems to be giving you problems with DOMESTIC US Carriers. I will be able to make a DEFINITIVE test in 2 months, because I am going to Peru and I might as well take this phone with me so I will test the Sprint HTC One M7 with both Claro and Telefonica SIMs down there. I will even try to update to the LATEST Sprint Official ROM to see if the unlock stays and if I am able to get GSM to work with overseas SIMs then the SIM UNLOCK worked, but you might as well not bother using it in the United States, so hopefully this will help others once I post an update after July and this will end up my "overseas" battle phone unless I pawn it off over there.
See you then...

Yep.that's exactly what i've got-i did radio downgrade and was able to run SIM unlock app,but i can't get ANY signal from ATT and my GSM network selection menu is greydout. Any ideas how i can make it work?Suggestion from OP?
i tried both methods ... same results (Not Working)
WLS Hboot 1.61.0000 with stock Lollipop all steps DONE but it says on lock screen INVALID SIM & SIM UNLOCK HELPER didnt show menu after hit start
on viper 8.0 also it says INVALID SIM on lock screen .. when i hit start its show MENU then i hit SIM LOCK it freez about 2 mins then it give me error (VDM isnt responding).. so i tried to flash HtcOMADM_SPCS.zip again then tried to flash Stock-HtcOMADM_SPCS.zip ... the same
what should i do ????

Note 5 FRP LOCK, phone doesnt open.

Hi guys, i have note 5 (n920c) rooted. I recently installed adaway, and program requests to restart and i press restart button.After that now phone didnt open.It says custom binary blocked by FRP lock.Im searching internet since morning.Therefore, as i see flashing stock rom with odin works.Now ı have 6.0.1 N920CXXU2BPB9(18 february) version but this version changed now it is N920CXXS2BPE4. Should i flash the older version which is exactly same on my phone or newer version? OR what can i do else?
Newer version
That means you accidentally turned off OEM UnLock which you have to keep Turn on Find it In Settings>About Phone> Keep Clicking Build Number Until It Says Developer Mode On Then Go Back To The Setting First Panel And Look For Developer Options And Turn On OEM Unlock And Then You Should Have That Problem No More. Only Fix To Get Your Phone Back on Restore It To Stock Samsung Firmware Heres a video that teaches how to Unroot what you need to do to fix it: https://youtu.be/RRzIvcJDyEA After you do what the video tells you follow the setup screen and put you last google account you had before having that issue.

Security Error and Network Lock

A few days after updating my phone to Nougat, my phone restarted itself, and after the restart, a security error showed up saying "This phone has been flashed with unauthorized software and is locked", and after unlocking the phone a screen came up saying that my device has been network locked and it can be unlocked using the device unlock app, and the invalid sim card error.
I was never rooted or anything like that, my phone had received OTA updates. I did not master reset, but I rebooted many times, and the error message appeared on every boot, but disappeared after a while allowing me to use my phone. And now, although the error doesn't seem to appear anymore, i still can't use my network, and when I checked the IMEI, it had changed to 350000000000006, and the one on the back is different.
Is there any possible way to fix this without sending this phone back to Samsung/T-Mobile for exchange, because I had bought this phone from USA but brought it to Pakistan, and Samsung Pakistan says that they would charge me for the repairs ( I still haven't visited them, they told this to me through mail).
HELP PLEASE?
Bump?
Have you tried using Samsung Smart Switch?

I didn't try Samsung Smart Switch, but I had reflashed it using Odin, and tried a factory reset and it didn't fix it, i got it fixed through Z3X box.
This happened to me also.

I had taken in to a repair shop who had a Z3X box. That's the only way to get it fixed. He downgraded my phone to Marshmallow and re-flashed the cert. I live in Pakistan and that costed my Rs.1000 (i.e. $10). Make sure you take your phone's box with you as a proof of purchase because changing IMEIs is illegal in many places.
P.S. I can't upgrade to Nougat now, if I will, the phone won't register to the network.

Thanks mate. I also live in Pakistan - Lahore. I took my phone to Hafeez center and they charged me 1500. Now the phone is on Marshmallow. I'm receiving notification of update. I've tried 3 times but if failed to install. When I tap on update it downloads the OS which is about 1.3GB. then restarts to install but it fails when reaches 30%.
Can you please tell me why we can't update our phones. I'm using another s6 which is also of T-mobile and it's running fine on nougat.

Not sure about that but we can't update because probably our CERT files have been patched in EFS is messed, I got it done back in July 2017, and at that time, the guy who repaired it said that they didn't have Z3X's software update for Nougat, so they had to downgrade my phone to Marshmallow, and the patch they used won't work on Nougat. Don't know about yours though, maybe he used an updated patch or a different tool, you can ask that guy whether if its safe for you to update to Nougat or not, if he allows it, then try flashing Nougat through Odin, if it doesn't work you'll have to get it patched by him again. Don't update if he doesn't allow, otherwise he won't patch it again without extra charges, and if he allows that and something goes wrong you can blame him for that

chinese N920T board - another ROM

Hello everybody!
I flashed a lot of phones, however I am struggling with this Note 5 N920T a bit. Bought this mobo from Chinese reseller, looks like everything is working okay, however if I want to update the software, it reminds me that ROM was changed and I need it to flash it over cable. I am perfectly aware of ODIN, however the board is unlocked now for all the networks globally.
I tried to check the T-Mobile Device Unlock App, however tapping on a "Permanent unlock" option brings me message "Unlock failed" - try to reboot and try again.
So, questions!
1. I downloaded the Nougat original ROM for T-Mobile USA and generic ROM. Would you say that the device unlock will remain after flashing? I would try the T-Mobile firstly, if that will work, I´ll try the generic one. I assume it will be working again...but that sim unlock...will it last?
I wanted to do full backup, however the board is not rooted so I rather asked the reseller for sending me the ROM file that is actually in the phone (currently waiting for it)...and just roaming around about possibilities.
Thanks for any help in forward guys, you´re the best!
The unlock was probably done through third party software or a EFS method.
You can forget about the Device Unlock app from now on. It will remain unlocked as long as you don't rebuild the NV data.
That means that you can flash the T-Mobile firmware on it, or you can flash any other available custom ROM that can work on it.
The update error is probably appearing due to an unofficial system status.
Go to Settings>About device> Device status and make sure it says official.
If it says "Custom" then you have your answer. If it says "Official" already it's good to be flashed with the software of your choice. Is up to you!
