Guys im about to freak out, I just got a phone en ebay that is locked, i knew that it was locked but I was not expecting this type of lock that I needed the original samsung account to unlock it, even after factory reset!!!
I have tried different options with odin but not of them worked, I also saw some videos in youtube to bypass this screen but they do not work know because if I press the button of "forgot your ID or password" it says that I need to go to account.samsung.com.
I cannot access to the phone to see what version of android is this...
Please there has to be a way!!!
many thanks
Nobody????
ok guys iI may have an answer, I need to downgrade to 4.4 from G900VVZW2BOK3_VZW, how can I do this??? somebody please help!!!!
There is no downgrading from ok3
So you tried getting the stock OK3 firmware (didn't know this existed, we have OG5) and flashing with ODIN in Download mode?
https://samsung-firmware.org/download/Samsung GALAXY S5/769o/VZW/G900VVRU2BOK3/G900VVZW2BOK3/
As ldevereaux said, as of OE1 Verizon has made the phone non-rootable (and thus no custom recoveries) and non-downgradable, so you will need to keep working on the current version your phone has on it.
Guys, I was able to open chrome in the phone so I can access nearly anything on the phone but is still locked, I go to uncheck the reactivation lock but when I do that it activates again by it self... how can I do this permanently! i can install any app, go anywhere on the phone, but it still locked!!! If i shut it down i wont be able to access again.
Sounds like you'll need to contact the seller to get the password.
http://forum.xda-developers.com/showpost.php?p=52467489&postcount=5
do you guys think he could put it into download mode and flash the stock stuff so he could atleast get the passcode off of the phone?
the seller doesn't have the password either
That sounds fishy to me. They have to use the Samsung software to remotely lock the bootloader, which requires them accessing their Kies account that they created. Hate to say it, but I think you bought a stolen phone.
well yeah it seems it is stolen, i got it in ebay and the seller said he got it locked from another person..... I wasn't expecting this kind of lock.. never had a samsung before...nothing I can do... i will keep trying I already spent my money on this...
try flashing the original stock firmware and everything from odin and it should be just like a factory reset and itll get the passcode off
Already did that.. was the same... keeps requesting the stupid passcode
Hello fellow people of XDA!
Today I got an OTA update for my S7 edge (SM-G935F). The update has installed fairly fast (after the first reboot). But then, it got stuck on a decrypting loop. I have enabled prior the full phone encryption, and set it to ask for a password at each start. I entered the password correctly, as it said Starting Android... after, and since then, only the rotating padlock is showing. Every like 5 minutes the soft buttons are lighting up for a second, but then nothing is happening. After a while it even gets hot, but still nothing. I had this issue at the previous update too, but it started after like 30-40 minutes. Now 90 minutes have passed and still nothing.
I can reboot to the recovery and bootloader screens, and everything is fine. Knox not tripped, not rooted, everything official. In the recovery screen it says that my CSC is ECT (but according to sammobile it should be CNX).
Some additional info: samsung/hero2ltexx/hero2lte
7.0/NRD90M/G935FXXU2DRAG
I will try to flash a stock rom (PDA: G935FXXS2DRAA, CSC: G935FROM1DQJ3). If that doesn't work, I'll flash today's rom (PDA: same, CSC: G935FVFG1DQI1).
Any tips/help would be greately appreciated! Would not want to fall to the wipe data method, because I don't want to lose everything... But then again, I guess that would remove the boot password...
Thanks!
Update: After waiting for like 10+ hours, nothing has changed. Maybe I shouldn't have forced a reboot after an hour of the ota update? Going to try flashing the firmware now.
Update 2: I flashed the firmware, now the buttons seem to light up less often. But after an hour of decrypting, I guess the ultimate soultion would be to do a factory reset, since no one is helping...

I set a password when I enabled Secure Startup.

Then use that same password, i think there is confusion, there is a password when you enable fingerprint and then a password when you enable secure startup. Be sure not to confuse them. If it still happens, then I guess there's got something wrong with the update, and only way is a factory reset. Btw, i also updated and i normally entered secure boot password and it started okay. Don't know what caused this for you.

I entered the password correctly, as it stated "Starting Android..." then the rotating padlock took forever. More than 10 hours even. But in the end, a factory reset helped me. But rip my photos and memories...
Don't use device encryption anymore and leave OEM unlocking enabled in developer options.
Those two settings cause more hassle if you want to keep data, and make backups from time to time using Samsung Smart switch on computer. Use a microSD card to store and take all your photos from camera.

Right, but i use encryption and i could update without any problem, don't know what caused this issue with him. But one should backup all data BEFORE updating, as i did to save yourself from such hassle.

Yeah, it's a sure thing I won't turn on Secure Stratup anymore. I don't know what OEM unlock does or does not, but right now, I don't have dev options enabled. If I had a microSD then I couldn't care less about resetting my phone, but since I don't have, because I have two SIM cards and a memory card has no place left, I feel bad.
Still, I don't know caused this issue. I had OTA updates before with full device encryption enabled and I had no issues before. I kinda used the same disk space at every OTA, so it should have took the same time... And I have to mention, that I did not tamper with the software. No root, no custom rom, and software only from the play store.
To enable developer options you click Build number 7 times which is located in the Software information tab in settings.
OEM unlock allows you to flash and boot the phone with custom binaries (Custom Recovery, Kernels, Roms). You can leave OEM unlock disabled if you don't want people that may steal your phone and use it for themselves.
With OEM unlock disabled and a google account signed in, it will block anyone from using the phone after a factory reset on stock Samsung firmware as it will prompt the user to enter the google account that was associated with that device.
Unfortunately there are rare cases that a OTA update may fail. Reflashing correct stock firmware usually fixes it but in worse case scenarios a factory reset will be required.

Never had OEM unlock enabled, because I didn't know what is does, so thanks for the info. I reflashed the correct stock firmware, but that didn't help either, so I had to resort to wiping the data... Regarding this, do you know by any chance a good software for recovering data without root?
I don't know of any unfortunately, if anyone has any good paid ones that actually work please post here.
Excellent news and a solution i havent found anywhere else yet!
Follow up from - https://forum.xda-developers.com/galaxy-s8/help/restore-imei-attempt-stock-rom-flash-t3802527
TL;DR attempted to re-root as soon as the bootloader unlocked. It all seemed to stick again, and got the big red message of doom again.
"Official Binaries Only" - Last time i was able to restore to at least switch on the phone to run down the rmm state timer to zero to flash again.
Tried the several methods of flashing through a locked bootloader (old BL file, quickly restart download mode and spam start on odin, etc) - literally nothing would allow me to flash anything that included the BL file. IMEI and baseband remained unknown. Phone went in drawer for a few days.
Just went and downloaded the latest XSA (Australia, Unbranded) build - https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/XSA/ and guess what boys and girls?
This sucker flashes straight away with Odin 3.13.1
It has completely restored my IMEI and baseband, i now have full Cell connectivity again, and its all back and working again. OEM unlock is still disabled, Samsung Pay still locked out which is fine, but otherwise, i have gone from brick to fully working Exynos S8 again.
TL;DR IF YOU HAVE ISSUES WITH A BRICKED PHONE BECAUSE IT WONT LET YOU FLASH ANY STOCK ROMS TRY THAT ONE.
Thanks for the replies to my other threads trying to help out with this. Much appreciated.
Peace out.
For heads up for other after this, how to get OEM unlock to pop up again.
Go-to date and time, change the date to 8 days prior, disable automatic update of time.
Reboot phone and it may take a few tries, but OEM unlock should pop up again in developer settings.
Just went through all this without any help and it sucked lol. Thanks for making this thread for everyone.

Thanks for the info tho ill keep trying.

I havent been inside since i replied to you before. Gave up trying to fix that and was doing other things. Just reset both the s8 and s8+ to look at download mode... noticed the rmm flag was GONE rebooted and sure enough OEM Unlock is done.
You genius.
So - Anyone actuallly reading this -
Lost root, reflashed and cant install TWRP etc, "OFFICIAL BINARIES ONLY" crash, cant replace bootloader, missing IMEI/Unknown baseband -
TRY FLASHING XXU2CRED stock rom from 18/6/18 or later. This will flash despite a locked bootloader.
Once up and running set up the phone for use. Reboot as normal. Then turn off automatic time and date set date to 8 days prior, reset phone a couple of times. Get annoyed because you keep having to reset the date backwards. Reboot phone again and set automatic tin me and date again. Reboot. Bamf unlocked and completely restored SN-G950F.

Ah I should have also mentioned I also did the same, flashed the same firmware when I was desperate and after some bit I also noticed prenormal change to official in download mode (the tell tale). I had OEM unlock on always, just was stuck in prenormal mode and couldn't flash anything.
To speed up the OEM unlock trial and error process do this as well:
1. After setting time/date back 8 days (and auto update time off). Go-to updates in settings, select manual update and check the server (it will error probably but that sets a check on their server to allow the RMM state to change next time it's connected properly).
2. Do this quite a few times, with reboot and constantly fighting the date auto update.
3. Flash the CRED firmware mentioned, boot it and setup once. Then reboot and go-to download mode.
4. You should see official as the RMM state now and you can happily OEM and flash away!

Have just flashed TWRP, used the Comsy version to be safe (3.13.1 fine for the stock rom flash) - I used comsy as it is mentioned in hte post OREO S8 update. It allows TWRP to be flashed but maybe thats whats breaking everything else. Ill try magisk next.
Fire up TWRP and enable system changes. FIRST - Advanced wipe and format system (Im 99% sure this is what screwed my last couple of roots), hit yes and do it. Reboot into recovery again.
Flash no-verity, then SuperSU (or your preferred root, i use Aroma installer first, THEN you have to flash the SuperSU binary with that)
Wipe dalvik etc. Reboot into system. As i type this its now in the 'Welcome' screen. Gimme a minute and ill check all is good.
UPDATE - Everything restored installed titanium backup root held. Rebooted phone aaaaaaaaand - "Only official released binaries are allowed to be flashed" - Back to square one. Will attempt same reflash now, but the root procedure kills everything. Back in download mode again. RMM State: Prenormal returned.
It is now succesfully flashing the stock rom in Odin 3.13.1 - Accidentally started it with Comsy and it DID NOT WORK. You MUST use the normal version to flash the rom im using.
Looks like we def have a stable way to refire up the phone again, and get around RMM state prenormal nice and quickly, so ill go ahead now and try and find whats going on with things breaking afterwards!
Thanks again guys.
Did nearly the same as you, dejavu.
I use magisk though. Be sure to flash a rom or kernel with RMM state fixed lol, or you'll be back here soon.

Someone should clean this up and get it stickied.
I imagine there are alot of users here with this same issue, after the CRED update we can't downgrade our bootloader, and in a panic you can get stuck here.

Looks like that wont be an issue any more to be honest this phone is now a backup thankfully so i can play around with it to my little hearts desire.
Im about to try the magisk install. SuperSU/Aroma definately breaking something somewhere. Or verity. I dont know but rooting the phone at the moment is killing it again.
Also, i have NOT lost IMEI or baseband this time. At the very least for Australian SN-G950F phones, this is a 100% flashable stock rom regardless of your RMM or phone status. I cannot say this for any other model in any other country on any other carrier, but this is all working for a carrier free Exynos S8.
Maybe y'all better archive the actual stock somewhere before someone realises theyve made a mistake somewhere and it gets pulled. Im definantly backing it up.
I just got that oem unlock trick to happen in 2 shutdown/restarts NOT reboots. BUT. I did NOT enable developer mode until i had disabled automatic time updates and turned the date back 8 days. The option came up instantly. Is something comparing a hardware clock deep in the system to a software clock in the os to and developer mode comparing something in between? Either way, on to reflash TWRP again now. This is a good day.

Hokay so - From a factory refresh, to the OEM unlock trick -
Flashing TWRP with 3.13.1 and allowing the phone to reboot - Phone will reboot as normal, TWRP doesnt stick. Shutdown and reboot into recovery gives you stock recovery.
Flashing but ensuring phone reboots directly into recovery gives you TWRP. A format data and reboot directly into twrp again lets me install no-verity.
- AFTER DOING THIS I AM GETTING THE RED LINE OF DEATH - Something in the system isnt letting the modifications stick.
Reflashing with the Home_CSC still seems to work as normal and i havent had to go through the welcome stuff this time...

Have you found and used this after getting your phone setup right (w/twrp)?
I think you should flash magisk, then this after.
After I had this "panic" I flashed the custom rom I was aiming for (once RMM: Official). That rom has a kernel with the RMM state fixed/locked.
Maybe look for a custom kernel if you want root, I believe this is the fight we have to put up even on stock w/root.
Download the Australian stock rom and install it but do not recover IMEI or coverage. I think it's because my G950F (singlesim) cell phone thinks it's G950FD (double sim). This causes the cell phone to get confused and not recognize any imei or sim. Does anyone know how to fix it?

I was stuck here too, flash the latest CRED firmware he linked.
Then boot it one time (setup til you see launcher).
Do the OEM unlock method.
You can follow the steps after if you want root.
I suggest magisk and a custom ROM, that had RMM state fixed (so you won't get locked again).
Good luck!

Sorry i missed your reply i hope you got it fixed if not post again and ill see if i can help. Ive definantly gotten that oem unlock trick working which is awesome but its fiddly. I dont think it works if you turn on flight mode and you have to let the phone fight you between 'no automatic date and time' and the network forcing the time.
Of course now i cant get the oem unlock trick working...
RE the dual sim issue... i think you would need the stock rom specific to your model try sammobile, see if there is a CRED release for your model. I cant guarantee it will work tho.

Thank you for your help, I am on the latest firmware now and into my Google and Samsung accounts. I am a little confused on the wording in the oem steps. I have tried it a bunch of times. Prenormal is still there, I already have the OEM unblocked, I can toggle OEM on and off but it doesn't change my rmm status. I am not sure what I am doing wrong.

Thats exactly what im now struggling with. It absolutely did work twice but i cant get it to go now.
Heres the thing - both times i did it before, i would turn off automatic time and date and set the date backwards, then reboot the phone, when it reboots, automatic time and date were rechecked, and the date reset to now (hence the 'fighting with the date' comments) ... i think thats important, because now when i try it, automatic time and date stay OFF, the date does not reset, and i cant get the trick to work anymore. No amount of wifi/airplane/mobile data on/off seems to change owt.
If anyone reading has any ideas it would help.

I see, so you suppose to set date back 8 days and turn off auto time and date and restart phone? When it comes back on to and set the date back to 8 days again? I thought you have to check the software? And then do those steps? So after I change the date back after that first restart, then what? Do I just turn OEM lock on and check download mode to see what the status is? I am not trying to be a pain o am just confused a little on the steps. Thank you for all your help

I think we might be looking at different issues.
This is to fix a semi bricked phone that has locked up its bootloader. In the past to resurrect a samsung all you had to do was flash twrp and your new rom but since Oreo some funkiness has been added to the system which only lets you flash a stock rom, (i.e. restoring a phone to factory settings and software) via ODIN/HEIMDALL then it locks up the bootloader for a week so you CANNOT flash anything into the phone that modifies the bootloader (i.e. TWRP OR *any* rom) until its timer runs out. This is most likely an anti theft feature esp with samsung and google pay use as it means there is no way to easily break into a stolen phone and use it as normal, and reflashing breaks all of the security features of the phone (e-fuse) - no knox no samsung or google pay no samsung pass as your device is insecure and could spoof false banking details etc.
The rom i linked to is important as it is a new AUSTRALIAN unbranded STOCK rom, that for some reason you can flash OVER a locked bootloader, meaning you can resurrect (australian at the very least) SN-G950F phones (exynos)
If you already have a working phone and can get to your developer settings then most of this thread is irrelevant to you.
Now - OEM unlock - You just bought a brand new galaxy from samsung (or youre me and you bought a MINT second hand one from cash converters for $700 less) - your phone is factory standard and schmicky. THE BOOTLOADER IS LOCKED. THE RMM STATE SHOULD NOT be triggered. If right now you went to flash something it would fail.
So you go to about phone - software information and you tap 'build number' seven times to unlock developer mode. Hit back twice and developer mode will be at the bottom of settings.
Click into this and you should see without swiping down 'OEM UNLOCK' - If you enable this, you can then reboot straight into download mode (power vol down and bixby) and flash twrp or whatever rom.
If you dont see this option, you either have a snapdragon model (youre **** outta luck permanently) or RMM is PRENORMAL and you either have to try the unlock trick(s) or leave your phone SWITCHED ON for 1 week and it will unlock itself.
The biggest issue at the moment is that i keep breaking something after i attempt to root so not sure whats happening there so use major caution.
Now as i said the trick posted above to unlock without having to wait a week (which i think youre asking about) im now not sure how it works because i cant get it to work any more.
Automatic time and date off, set date back 8 days, reset the phone. Do this a couple of times, then turn on automatic date and time again. HERE THERE BE ISSUES. When i first did it - i switch off time and date and change then reset, when the phone came on, auto date and time was on again. Turn off, change date, reset. Again, its back on. Turn off, change date, reset. Its back on. I give up and leave it, and notice later the option was available, so it worked. I broke the phone, reflashed again, did the trick in ONE reboot. Fcked something again, reflashed, now auto time and date stays off and the trick wont work so i cant help you with that until someone comes up with more info im sorry! Its a bit zarbis.
Im not going too nuts trying to fix it as i now have a fully working stock backup phone that sits on DeX plugged into my bedroom tv full time and im not into custom roms, root keeps breaking the phone, and ive sonce replaced it with a mint S8+ that im not even THINKING about considering rooting until its replaced maybe next year. Its not as easy to get around anymore and thankfully a) picasa and hangouts are no longer stock apps and can be banished and b) you can now disable all the other built in apps natively so its now a lot more bearable with a totally stock phone.
hello,
i managed to get the phone back to get in download mode. stock everything, no root whatsoever. my goal is to root my phone and i have experience doing so but i guess i was just unlucky this time.
i tried searching allover the internet for a fix, searching xda etc.
first off: my device is running oreo 8.0 and it's type is G950FX.
I want to downgrade to 7.0 because FRP lock is on, i did turn on oem lock before starting however i am unable to log in to my old google account connected to my phone.
when i try to flash any bootloader i get SW REV CHECK FAIL DEVICE 2, BINARY 1. i tried almost any trick in the book like downloading 7.0 from sammobile, flashing using odin.
the things i run into when flashing are:
1.can't flash the bootloader, probably because of frp lock.
2. when i don't flash the bootloader for 7.0 i get dm-verity error 0x2.
3. when i only flash 8.0 oreo pda & csc and then flash 7.0 pda on top i do get to boot but i get encryption interrupted error.
4. i am able to boot in 8.0 but can't get past the frp.
i'm out of answers, i really hope anyone can help me out of this situation as i want to use my phone.
Help is much appreciated!
edit: i tried flashing multiple versions of android 7.0 but i keep getting sw rev check fail bootloader device 2 binary 1
i basicly want to do this, a downgrade: https://forums.androidcentral.com/s...s8-plus/878062-how-downgrade-oreo-nougat.html
the problem is i didn't sign out of google or samsung accounts before resetting to factory
You can't. You have a new bootloader v2.
A simple search gives you this answer, if you have u2 and CRED bootloader installed you are stuck. No way to go back anymore.
i'm on u2 and CRED bootloader. i did search for this indeed but i didn't want to give up.
do you think there will be ever be a way to get back into my phone again?
If you have FRP lock good luck. I haven't seen a way yet.
I know it's been 5 months and you've probably either gotten rid of the phone or it's sitting in a dusty bin somewhere, but have you tried Galaxy Reaper? It's a pretty legit FRP bypass tool.
Edit: Scratch that. It's apparently been patched since I last knew it to work. Just wanted to double check, and sure enough..
Hi, recently I accidentally bricked my Galaxy Tab A 10.1 with Spen (SM-P580) by accidentally disabling "OEM Unlock" in the developer settings while I had TWRP and a custom ROM installed. I was only able to get into download mode due to the factory reset protection lock, so I tried downloading the stock firmware online and then flashing it to bring the device back to fully stock firmware so I could get past the lock and not have a brick. Unfortunately, when I flashed the firmware, despite it seemingly being for my specific device (and matching my build number), I was no longer able to boot the device at all. It would turn on and would seem to immediately lose power, charging would turn on the flash and cause it to heat up, and no amount of charging would fix the issue. It was completely bricked and there was no way for me to go back into download mode to try flashing again or try flashing a different firmware. Thankfully, I contacted Samsung and because it's still under warranty they were nice enough to fix it for free, and did so by completely replacing the motherboard according to the repair slip, which is not something I would have been able to do.
My question is: How do I make a full backup of the stock firmware and recovery so if this somehow ever happens again where the FRP lock kills my device, I can reflash in download mode the original firmware that I know is 100% going to work with it and is correct? I don't want to gamble with potentially using the wrong firmware again, seeing as that gamble killed the thing.
The Model is SM-P580NZKAXAR. Based on the last part (XAR) and the fact that other non-sammobile sites listed the US wifi only firmware as XAR, I assumed "Cellular south (XAR)" was the correct firmware I needed which was obviously incorrect as it completely bricked the device. For this reason, I'm wondering if there's a way with software on windows or something to completely backup the existing stock firmware before I do anything, because I doubt Samsung would be so nice a second time, and I'd really rather not go through all this again. Obviously these websites get the original firmware that's flashable via download mode somehow, so I'd like to know how or if that's possible. Also before I went and downloaded the firmware I checked the Samsung desktop app that allows you to fix firmware issues but it said my device wasn't supported so it wasn't much help. I'd like to avoid installing any custom recoveries ahead of time as if something gets messed up there will be no way for me to actually boot into recovery as far as I'm aware, and the FRP lock will block me from reflashing the custom recovery or anything else that isn't stock. It goes without saying that if this is possible I'd like to do it without installing a custom recovery or rooting as I'd like to have a proper fully stock backup that isn't going to trip the FRP lock.
Also the way I accidentally disabled OEM Unlock was I simply toggled the developer options off and then back on in a slimmed down version of the stock rom, but in doing so it also reset the OEM unlock setting and I completely forgot to make sure it was still enabled. Next thing I know I go to reboot (was trying to figure out an issue with a usb device) and then the thing was FRP locked. Needless to say, it was something extremely simple and easy to do by accident. I also just checked the device and the build number matches the firmware that I downloaded, so I don't know if it was mislabeled or what but something was not correct.
