Samsung s8 software problem

So i have an Samsung S8 SM-G950F. I made a factory reset on it but because i forgot my synced google account username and password on it i wanted to flash the same software again on it so i can use it again but forgot to click the OEM Unlock option. Now i flashed custom binary on it and with ODIN i tried to flash my new firmware but nothing happened. And when i enter in the custom binary in developer options there is no OEM Unlock option? What can i do. They told me the only way is to change the main board of the phone. Is this true,i mean the boar costs as much as the phone ...

You have to wait for 7 days without the phone dying or being turned off, then the oem unlock option will appear, I take it you flashed oreo?

So you are on nougat right now, ignore what I said then about waiting 7 days, as far as I know it applies to oreo, I mean you can wait and see if you want but apart from that, have you nor acceded your gmail account on a computer or laptop or anything? Maybe try to recover the username and password that way, my Google account is my main email account so that makes it handy for me when issues like this occur, not sure what else you can try

How to recover Galaxy Tab A 10.1 (2016) without factory reset?

Hello, I need to access Galaxy Tab SM-P585 which belonged to a friend who has passed away, so pattern, pin and Google account info are unknown. Also firmware is original from Samsung, developer mode is disabled and OEM locked. The only options available are recovery mode, where I can do a factory reset or enter sideload mode, and download mode. I have found this guide https://forum.xda-developers.com/showthread.php?p=49666433 to bypass pattern but custom recovery is needed to use either Pattern Password Disable or Aroma File Manager methods. Then I have tried to install TWRP via this guide https://forum.xda-developers.com/ga...covery-official-twrp-galaxy-tab-10-1-t3473023 via Odin however device returns error "Blocked by FRP Lock" which from my search is either Google or Samsung https://www.samsung.com/us/support/frp/ Is there a way to access this device without factory reset?
Regards

Try and reflash it using Odin with a stock firmware, that might work. Get your firmware from Sam Mobile firmwares. Just make sure you get the exact corresponding firmware...
Let me know how you go...

Thanks, I've looked up for SM-P585 model but found only firmwares for ME and Africa. Tried with South African version but got SECURE CHECK FAILED (BOOTLOADER) error, which I believe is because it is not exactly the same version. From the recovery menu I've found out that I need 7.0/NRD90M/T585XXU2BRB2 version (multi region) so now downloading from samsunggalaxyrom and getdroidtips. I'll see how it goes with either one...
P.S. From the instructions "Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data." so I'll use HOME_CSC_ file to keep apps and the data.

If you use CSC it will wipe the device along with any security measures set up and basically put the device back to factory setup.

Unfortunately HOME_CSC didn't work, security settings were still there, so I have applied CSC. However now FRP requires me to logon using original Google account, even after factory reset, so this functionally means that device is only for a dumpster?

Not at all, FRP can be bypassed.

Re-Lock Bootloader on Galaxy Tab A T510?

Does anyone know if it is possible to re-lock the bootloader on the Galaxy Tab A T510? If so, would I begin with flashing back to stock firmware then disabling OEM unlock in developer options or following different steps? I certainly want to avoid bricking the device. I've searched for a solution but can't seem to find anything. Thanks!

You need to download the latest stock firmware either from Samsung or Sammobile and use Odin to flash it. DO NOT DISABLE OEM!!!! That has nothing to do with locking the bootloader. Flashing the stock ROM will do that. The OEM enable only disables the FRP lock which makes you login with the same google account used BEFORE a factory reset. If you are sure you know that account login and password, the FRP lock isn't a problem.
edit: The problem with the FRP lock is that people will often create a new google account login and password when first setting up their tablet. And because you only have to do that once, they tend to forget one or the other. Then, if they do a factory reset without the OEM enabled, they are locked out of the tablet.

Thanks for the detailed information and clarification. Your help is much appreciated!

The T510 doesn't have a locked bootloader.

No, but it does "lock" the tablet from getting OTA updates.

I have reflashed the stock firmware however I'm still receiving the following message during boot..."The bootloader is unlocked and the software on this device cannot be verified". Is there a way to remove this message? I am planning to return the device and I want to reset everything. Thanks!

Hi! I've inherited a SM-T590 (among various other devices) from a deceased relative and try to figure out how to unblock them. I flashed the engineering image and turned on ADB but I don't see how to get rid of the FRP from there. What would be the next steps to disable the FRP entirely?
Thanks!

Once you flash the eng ROM, which you have, go into developer options and enable OEM unlock. Then factory reset within the settings. After that you can flash stock and frp will be disabled.

That worked! Thanks a lot!

Hello,
I know this thread is old. I have almost the same problem, except this is a familly kid who forget his lock screen password, and he used a dummy email adresse to create google account... And android version is 10, not 9.
So we did a factory reset from the recovery menu. But, now, we have to enter the google account, and of course, he doesn't remember.
I tried some (non trusted) tools as samsung frp tool, but not working. I tried a combination rom (i don't know if this is the good one), but in the download mode, the device tells me that :
frp is enabled, ignore pit download.
I tried to flash latest version 10 stock rom, but no change.
Is it worth to try to flash with a stock rom version 8 or 9 ? But to get these roms, i have to pay, but no garantie that this will work...
The device is not in debug mode, of course, and oem locked.
In the second post of this thread, there was a google drive link, but it's dead.
Do i have to put this galaxy tab a tm-t590 to the trash, or is there some hope to unlock it?

Finally did it.
I downgraded using odin in Android 9 using a stock rom, for 2.99$.
https://samfrew.com/fr/download/Galaxy__Tab__A__/gi1r/XEF/T590XXU3BSG3/T590OXM3BSG3/
I tried again samsung frp tool that I trust now .
I followed this video:
But the step *#0*# didn't work. So i tried to launch some apps from the web launcher.
I didn't remember exactly how I did it, but I succeded to create a new google account.
I restarted the device, and and i'm now in android. I activated debug mode and disabled oem mode.
I will try to flash something new and maybe alternative firmware.
I don't know which, but I will search here

T580 - Suddently got FRP Lock after over 6 months of use. Any way to recover?

Hi Guys,
I have a couple T580 tablets for my kids, and we had just gotten a new one for Christmas that I set up. I THOUGHT I had done everything correctly, but the new tablet is giving me the FRP Lock suddenly.
Any idea how that could happen? Is there any way to recover the tablet or do I have to do a original rom flash?
Thanks

Somethings not right. You don't "suddenly get an FRP lock". An FRP lock occurs only after you "factory reset" the tablet and don't know the google account login. And that is only if you hadn't enabled "OEM" in "Developer options". What makes you think it is the "FRP lock"? And if it is locked, flashing a ROM with Odin won't help. You'll still need the google account info to access the tablet.

Because this is what it says when I start the tablet...

I have a google account, and info, for the tablet. Not sure how I put it in when the boot process is blocked though...
My only thought is something happened with Magisk?

Again, unless something has changed, which I doubt, that is not the way the FRP lock works. First of all, you said nothing about having a custom ROM installed. But even if you did, the FRP lock would NOT prevent the tablet from booting. It would merely ask for your google account info when it did boot. Have you tried booting into recovery and performing a factory reset?
edit: Let me explain what FRP means. In early versions of Android, if your phone/tablet were lost or stolen, anyone could bypass your "screen lock" simply by booting into recovery mode and perfoming a Factory Reset. So Google came up with the Factory Reset Prevention lock. So if someone tried to use the Factory Reset, the lock would demand the google account login and password to access the tablet. So if you wanted to sell your tablet, you either had to enable "Developer options" and then use that to "Enable OEM", prior to reseting the tablet or put in a google account whose info you could pass to the buyer, remove your real account, and then reset.
In any case, the tablet did NOT show the message you are getting. I've bought several T580s on eBay that WERE locked, and none of them gave that message. A locked tablet would still let you install stock ROMs with Odin, but the tablet would still ask for the google account info. But the way around that can be found in this forum.

When I turn on the power, the screen comes on, and then says "Custom Binary blocked by FRP Lock" then the screen turns off. I have not tried a factory reset because I was hoping to find a solution without losing everything before I did something that could not be undone.
The only thing left is, I know samsung will (if detected) attempt to remove software. I wonder if it somehow tried to reset automatically and in so doing caused this.

A factory reset does not help in your case.
First option is: contact your person, who sell the phone. Because he must unlock this one in his Google settings.
The question is: how many times a wrong oe no account was insert, that the device doesn't start up till the possibility to insert the correct account.

You don't lose everything with a Factory Reset and what you do lose should be easily recovered from your google account backup. And nothing else could be done that wouldn't also cause a reset.

No one sold me this phone, I bought it new. There is no unlock option. The phone doesnt event start booting, the screen turns on says the FRP lock, then turns off.

Ab FRP Lock said, that the phone is looked via a Google account.
In a normal case, you can only unlock the device, if you insert the correct Account with password.
I don't know.. maybe you have insert 3 time wrong credentials... why the device give your not the possibility to unlock the device.
Try an complete wipe / factory reset out of the recovery menu, so that the OS can start.
The lock isn't away, but maybe you have the possibility to insert the correct data.

In Download Mode here is what I see:

Alright I just flashed the latest rom and that fixed it.
I now know a little bit about what is going on. When I got the tablet, I set it up for me. Then I discovered googles "family link" so I set it up again for my daughter.
Child accounts have FRP protection. I dont know what triggered it, but somehow it activated recently when it discovered magisk which I had installed some time back.
Now I am super irritated and over Family Link...
