Is there a way to do a FULL Reset of the Note 8? Not just a Factory Reset which doesn't seem to be enough - I want to try to reset my Note 8 to how it was when it first came in the box. Removing the Region lock - CSC and whatever else is retained in the phone that is not erased when I do a factory reset.
Right now, when I do a factory reset, when the phone is booting up - it goes into a Android Update/ or system update and it essentially resets the CSC to the same settings it was before I did the Factory Reset. I am trying to circumvent that or prevent it in some way without bricking the device of course...
I am guessing that if I can do this, I can go thru a limited setup of my device and ultimately be able to do an OEM unlock in Developer Settings. This is just a guess for me right now, but that is my thoughts any way -
Any suggestions would be appreciated.
Samsung support is no help at all - I contacted them and they will not help me because it is an International Variant. They gave me a number in Europe to call - tried calling, can't get thru .
Flash factory ROM with oden. Have you removed sim card?
Sent from my SM-N950U using XDA-Developers Legacy app
Samsung smart switch for PC or MAC will download and install whatever the ROM supposed came from factory.
There's probably the option in Recovery. Older Samsung phones was to hold the Power and Volume UP til it booted.

I have a Note 8 N950U that was originally on ATT. It was bootlooping and I got it to work somewhat by flashing the ATT_N950USQS4CRE1_ODIN firmware using the moded odin file. The phone will boot and all seems to work but it will not work on a cellular network. It shows the "no network connection" error and the airplane mode switch is highlighted as if its on but it is not on. I've tried resetting the network settings, reboot with airplane mode on, etc. I also have tried several different working sim cards and all do the same. The phone does recognize the sim because it sees my phone number in the settings.
I recently reflashed the device using the N950USQS5CRG9 firmware, and still have the same issue. the device boots and all seems to work except the cellular network. I also tried different APN settings as well.
I seem to be having trouble with other firmwares because odin will just error out on me. These are the only 2 firmwares that I was able to get to flash. So is this a firmware issue or a hardware issue? I would really like to get this device to work if at all possible. So, any and all help is greatly appreciated.
TIA to all!!!

What version of the bootloader are you currently on now? And did you flash a CSC file from AT&T and then do a factory reset in recovery mode?

I am currently on N950USQS5CRG9 bootloader. And yes, i flashed this CSC file, CSC_OYN_N950UOYN5CRG9_CL13949550_QB19107689_REV00_user_low_ship_MULTI_CERT, which I believe is an ATT file. I did not do a factory reset in recovery mode after the firmware flashing. The device was factory restored prior to flashing though. THanks for the help, I've been messing with this for a week now...Thanks again.

Try going from CRG9 to N950USQU5CRIA because that could fix the problems.. Download the update.zip from the website put it on your SD card and then boot into recovery mode and select flash update from SD card and let it do its thing after you select the update file.. You have CRG9 still and you'll be able to flash back to it too if you have to for some reason.. The website is here put your model of phone in from the dropdown menu(Note 8) and then the next dropdown menu select your CRG9 firmware and it will give you some updates but take the latest version that's N950USQU5CRIA not the old ones after it flashes try a factory reset again!!

OK, went through and did exactly what you said do...the update went through and finished, the phone rebooted, and then I restarted phone and did factory reset, and I went thru the setup and the update did take, but still same issue. Tried 2 different sim cards that work in other devices and still no network connection and airplane mode is still highlighted as if its on. No signal bars just a 0 with a / slash through it.
Any other ideas? Really do appreciate the help. TIA!!

Try this.. From the home screen, tap the settings icon, scroll down until you see General and select it, scroll down until you see the reset option. Select reset. You will be taken to the reset screen. Select Reset Network Settings, if your phone is password protected, enter your code. You will be taken to a new screen confirming your selection.
And the last idea I have is that you have a hardware issue if the above didn't work and there's something broken internally and you need to go to AT&T immediately and have them either replace that phone or call Samsung because there is a 1 year warranty on the phone for free from Samsung and they'll fix it and return it so long as it's not from something you caused, like water or dropping it and breaking it.. Also, where did you get that phone from? Is the IMEI clear?

That's one of the 1st thing i've tried before anything else. It says it resets successfully, but does not fix issue.
Unfortunately, I got this second hand...It worked great until it started boot looping, so returning it, isn't an option. I guess the baseband chip
got messed up some how. Anyways, thanks a million for the help...it was much appreciated.
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.
Device: Samsung N960UZBAXAA
Firmware CSC code: XAA
Active CSC code: TMB
Device is unlocked & currently on Google Fi, running stock ROM
Got the android 10 update a few days ago, ever since then about once an hour I get a notification from OMADM saying 'firmware update not completed'. If I allow it to run I get error 407: the profile update could not be completed, at which point the update attempt cycles again and I get either 407 or 700 and it stops trying for an hour. Did a factory reset, no change, found a few other people on the Samsung forums with the same issue after the patch but no response or further info. Everything works, I can send and received texts + calls, but the firmware update message inevitably pops up again. Been reading up on using Odin, which leads me to my question- is it worth flashing the firmware myself/taking other steps I'm unaware of, or should I hold out in case of an OTA fix? And in the event that I do flash, would I look for firmware with the current CSC code, rather than the active CSC code?
Any and all advice appreciated!
Try wiping the Cache Partition in Recovery Mode and see if that helps. If it doesn't then take your device to a Samsung Service Center and let them take a look at it.

Wiped the cache partition after the first failure, did a factory reset during testing, no change. Starting to think that a t-mobile sim might change things but I don't know enough to say for sure. Problem about the service centers is that I live in the boonies and to my knowledge there isn't one within a couple hours of me, so I'll have to send it out.
In that case try downloading the stock US Samsung Version of the OS and installing that onto your device.
Samsung Tab S8+ won't update via wifi, I get a server error message when I try, last worked in June and since then it hasn't worked. Tried clearing cache, restarting and everything else I can think of. Contact Samsung, I'm just saying phew... not much help there. Anyone have a solution to the problem?
My Samsung Tab S7+ 5G is working fine on wifi, no problems at all.
Hi. To be 100% clear, you don't have the bootloader unlocked, and you're not rooted, correct? (Although I wouldn't necessarily expect the problem you're facing with both of those things)
Bootloader locked, no root, just like straight out of the box.
What CSC (Country Specific Code) is your Tab S8+? Quoting another user on here - I don't remember who:
Go to settings > about > software information > service provider SW ver
The region code (CSC) will be written there.

And what specific model number?
I don't really have any specific suggestion other than a factory reset, which I know is extreme, and wouldn't guarantee to fix the issue. You could always use the SamFirm or Frija Windows programs to manually download the firmware, and use Odin to flash it. As long as it's the completely stock Samsung firmware of any type for this device, it will work without unlocking the bootloader.
So I installed an app called CSWE App Manager and disabled some apps/services. Well, I must have disabled something I shouldn't have and my phone is boot looping. It shows the Samsung splash logo and then after a few minutes reboots and repeats.
Here is what I have done so far to troubleshoot:
I have taken out the sim/SD card.
I have booted into recover and wiped cache and factory data reset, but still no joy.
I downloaded new firmware and flashed via Odin. Got a successful flash, but still boot loops even after that. I downloaded this firmware from SamMobile:

I am at a loss for what to do now. Can anybody please help me? I am about to pull my hair out.
Thank you!
I took these screenshots of my wife's phone software info. She has the exact same phone as I do.
Unfortunately you may have to factory reset. Without knowing what the culprit is. If I were you, I would use ADB App Control next time. You can disable and enable with one click. And I would never remove anything unless you are sure, just disable
I tried to factory reset, but no luck. Still boot loops. I didn't uninstall anything, I just disabled. ADB App Control... is that an app?
I'm so frustrated, it successfully flashes in Odin, but still boot loops.
You load it on computer and connect device. It shows every app with the option to ddisable. If factory reset didn't work probably have to flash firmware with odin.

Thank you for the link. I downloaded that firmware and got a pass on Odin v3.14. Still boot looping. What am I missing?
Did you flash BL..AP..CP..CSC
So I flashed via Odin again and this time I didn't select for auto reboot. I powered down after the flash and immediately went into Recovery Mode. As I attempted to do this a blue android logo and status bar came up briefly and then went away, which was weird. Then it let me into Recovery Mode and I cleared cache and factory reset. Still no luck, boot looping.
Yes, I flashed all four of those as the same time.
Since you factory reset, try flashing again with those 4 files. Keep auto reboot selected. Use parched Odin I think 3.13b or patched 3.14
And if you can, show me your download screen
Ok, I did and still boot loop.
No I mean download screen of your device
Who is your carrier? What sim?

Mint Mobile
Try to find latest version of odin. Mint Mobile is basically Tmobile. Take sim out and flash the firmware.
I've got Odin 3.13.1 and have the sim/SD card out. Still boot looping even after successful flashes.
Here is the device info that I get when connecting to SamFirm to confirm what my device is currently showing.
Company : TOSHIBA
Model Number : SM-N960U1
Sales Model : XAA
SW Version : N960U1UEU9FVG2
FW Version : 000B
Product : THGAF8T0T43BAIRA
CAPA : 128
DID : 20208BB5CA97FF11
UN : 988F8B48425148474434
I also tried to Boot into Safe Mode. I am not able to shut the phone down while in boot loop, but when booting into Recovery Mode there is a power off selection. When I select it, it just reboots back into Recovery Mode.
When going to SamMobile to download the firmware package, how do I know what country to pick? I see XAA (unknown), AIO (unknown), etc...
My phone is the unlocked US version.
My wife has the same exact phone and it shows this as her software version.
It appears something in my phone is preventing it from booting even though I have successfully flashed stock firmware via Odin. Is there a way to completely wipe my phone via my pc using adb or something and reflash using odin?
I'm not sure what happened. You have done everything that should work. Try different cord, different USB port
A factory wipe should do the trick. Try flashing Tmobile U1 it's unlocked firmware..
Do you remember what you disable? Have you tried your wife's sim? You should be able to flash any unlocked firmware not just XAA they are the same since it provisions to your Sim my play phone is a Note 10+ with mint mobile Sim and it works just fine. Before I unlocked it I used At&t
This is my about phone on my Note 10 + with mint mobile sim
Did you ever use Odin to flash firmware before all this happened?
I have an have always been successful. Its been a long time however, but I used to flash custom roms all the time on my earlier Samsung Notes.
I was told by somebody more experience than I am after trying to flash for me that its an emmc error.
Is this fixable by a repair shop? Worth doing or would it be expensive?
I don't get it. I get a successful flash with Odin.
Is there anyway to fix this? Can the storage on the phone be repartitioned and the stock software reinstalled? I don't see how the emmc could just fail like that. Especially after I was using CCSWE App Manger and disabled apps. Seems very coincidental that the emmc would fail right after doing that. I think I messed up the software with that app. I just don't know how to get it fixed.
