HELP!!! Custom Binary (BOOT) Blocked By OEM Lock - Samsung Galaxy A20 Guides, News, & Discussion

Hi there, I've been having trouble rooting my Samsung Galaxy A20 - SM-A205GN for awhile now. I'm officially on Android Version 10 with One UI Version 2.0, I've followed the provided guide to root my device but it fails on Odin "all versions" when I flash the recovery.tar file. After it fails it gives me a prompt on my phone on recovery mode saying Custom Binary (BOOT) Blocked By OEM Lock. I have enabled OEM Unlocking and USB debugging but it seems like it doesn't enable is there a way that your carrier can block these options to not enabled because that's what my starting to think why I can't seem to root my device. Can anyone suggest any workaround or fixes for this problem.

While your phone is turned off hold down both volume buttons and connect the usb cable, it will give you 2 options just hold down the volume up button and your bootloader will be unlocked

This happens to the a207f because it has Snapdragon instead of Exynos

You have to flash Stock Firmware

Boot back to download mode and long Press Volume up button.
then you will be oem unlocked

....except not that I unlocked and relocked bootloader on s10e it won't show up again in developer options

[Q] FRP lock help--j700T Marshmallow

Hello,
I wonder if someone would help me FRP unlock my phone. It is a T-mobile sm-J700t 2015. I have searched the forum but don't see a clear answer.
I have tried (from Youtube) the USB cable method, the camera method and flashing the 10/2016 stock firmware through ODIN. In Odin I get an error: "Complete(Write) operation failed". I cannot turn on USB debugging of course because I cannot get into the device. Haven't tried updating with Kies yet because I'm nervous they'll patch any additional back doors I could try.
I am somewhat experienced at flashing and such and I think there must be a way to completely wipe the device and flash new firmware but I don't see instructions for that.
Thanks in advance!
Odin v3.10.7 & v3.12.3
Recovery: Haven't changed
USB installed from Samsung Kies (made sure Kies isn't running)

Anyone? Still locked out of my phone. :crying:
Reboot normaly > go to settings > developer setting > oem unlock check yes
#gggirlgeek
Reboot normaly > go to settings > developer setting > oem unlock > check yes
I can't get into the phone at all. It is FRP (Google) locked because I did a factory reset from recovery. I can only manipulate it from PC or stock recovery. I have ADB, Odin and Samsung Kies on my PC if that helps.
What is the reason I am getting the ODIN error: "Complete(Write) operation failed"? Is it due to the FRP lock?
If not, would flashing the same stock firmware even help? (I have read that it's not possible to flash older firmware versions.)
Is the boot partition where the FRP status is stored? Is it possible to flash a new boot image to reset it?
I assume flashing a custom recovery would be useless? I doubt it could be done without USB debugging/ADB being enabled anyway.
One of the reason for that odin error is flashing an old build of stock ROM, your guess is right
Even if you are able to flash a stock FW via ODIN you'll still not be able to boot to your OS.
You have to login using the same google id that was previously logged in
OR you have to bypass the Google Account Login Screen.
There are varous method on youtube (i know you saw them) to bypass that screen (Side Sync method worked for me at the 10th attempt) inorder to install a 3rd party app either to
1. enable the developer option or enable OEM unlock ( to flash custom ROM or custom recovery)
OR
2. to overwrite the previous google account saved with your new account details. (THIS ONE HELPED ME)
WITH FRP LOCK ON, ODIN SHOULD NOT GIVE YOU ERROR ONLY IF YOU ARE FLASHING STOCK ROM. BUT STILL YOU WILL BE LOCKED WITH GOOGLE ACCOUNT LOGIN SCREEN BECAUSE OF FRP LOCK ON AND STOCK ROM
FRP info. is saved in Sboot. Flashing a new sboot works only for devices those were never upgraded to Android 6. For J7 2015 that was upgraded to android 6, flashing Sboot bricks the phone as said by a cell phone repair agent

Sid
@saddam.khan999 : Thank you so much for replying. This is helpful. :highfive:
What did you do to get the sidesync to work? Mine wouldn't even connect to Sidesync on my PC.
Tried different USB ports, and even different PC's to get it to pop up on the phone. Tried old usb drivers too. Sidesync never senses it, and My Computer only show MTP folder that won't accept any file pasted to it.
You did this with Android 6.0.1 October 2016 update? They fix more holes every time.
Also, can you give me the link to the unlock tutorial you used with Sidesync? Just want to compare my method.

I followed below step to fix popup issue
1. Uninstall all samsung apps like, Kies, SmartSwitch, SideSync everything.
2. Uninstall Samsung USB drivers
3. Install SmartSwicth (to get best drivers)
4. Now install SideSync (latest)
5. Open SideSync and check for OTA updates in your PC (update it if available)
I give up. I'm going to pay somebody. He can use one of those low-level programs to unlock it remotely. It only costs $15. Well worth it. Wish me luck!

Not so simple.
During FRP Lock you are restricted to the google sign in page, locked out of everything else. Cannot even pull down the status bar. So no way to get to settings.
This can be done via ADB , but only if you had USB Debugging enabled prior.
I just obtained a used J7000T1 and FRP lock is activated , Even on the bootloader it displays "FRP Locked" . USB Debugging was never enabled .
If I find a way , I'll post. Any one have luck yet?
Once " FRP Locked " is off the bootloader, I'm sure we can just load a recovery / rom via Odin .... But that's where I am a stuck of course.

I had this happen last Feb when I got the phone and was trying to install twrp, and it says frp lock when I tried flashing the recovery tar via odin. I literally took out the battery rebooted back into the OS and turned on oem unlock and USB Debugging and it was fine then when I flashed twrp. I have never heard of this other issue u speak of. The phone has an unlocked bootloader to begin with. If u are stuck in a Google sign in page, I would download the Samsung z3 tool and make sure u have drivers installed and unlock the frp that way.it does have an option for frp lock

Drivers are installed.
Just cannot move from the google sign in.
There is a guide that shows how to use a USB drive with a shortcut apk on it , hooked up via OTG and is able to open settings. Although that did not work for me as well...
Maybe N version is different than MM ?
Almost the same problem here.....but in my j700f, I can't boot to recovery at all...can't flash stock firmware also due frp locked

[Completed] Samsung Galaxy Grand Prime+(SM-G532F) rooted and locked after disabling OEM unlocking

Hey guys, I'm new here...
Well yesterday my dad bought me a Samsung Galaxy Grand Prime+ SM-G532F (vodafone, South Africa).
I wanted to root it( i always used to use KingoRoot) but i found a thread with an exploit to root the SM-G532F/M/G or something like that. Anyways i used it and flashed the "root-boot.tar" and followed all the steps( Enabled OEM unlocking and usb debugging) and i had root access and everything was perfect.
Then i thought i didn't need the OEM unlocking and the usb debugging anymore so i disabled both. Then afterwards i rebooted my phone( Because i had just installed Magisk so i could play pokemon go on a jailbroken device and it required a reboot.).
As it restarted, I got this message on a light blue screen( i don't think it even booted), "Security Error: This phone has been flashed with unauthorised software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost."
I think this is because of disabling the OEM unlocking. I tried flashing a stock ROM(it was really small though, but am downloading a 1.5Gb one right now) using odin while in download mode( The phone doesn't have a recovery menu to wipe/factory reset. It goes straight to download mode) and it appears that the custom binary (boot.img) is being blocked by the FRP lock.
Here is what appears when i go into recovery(well download mode):
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-G532F
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
FRP LOCK: ON
WARRANTY VOID: 0x1 (0x302)
MTK SECURE BOOT: ENABLE
AP SWREV: B1 K0 S0
SECURE DOWNLOAD: ENABLE
I can't use ADB because it doesn't even appear if i try "adb devices" it is completely blank. But in odin it shows 0:[COM4]. Is this because my usb debugging is disabled? Can i flash with odin if usb debugging is disabled? If not, is there a way to enable usb debugging with the phone only in download mode( As in no ADB recovery or updating from sd card etc).
Please help. I really need to fix this. Even if i lose everything on the phone it's fine since i only got it yesterday.

Greetings and welcome to assist. FRP lock shouldn't prevent you flashing stock rom, the easiest way to restore your device should be with kies/smart switch and using the emergency firmware recovery option

Hello friend, maybe you can try to download and reinstall the same rom you have and use odin to install it, the rom will give you a clean system later you can try to enable OEM again!

Fastboot, Samsung Galaxy A51

Hello, i wanted to ask how to fix the fastboot mode.
Everytime when i try to access it, it just says "Entering Fastboot..."and thats all.
I dont want to close it, thats not my problem, i just wanna flash a recovery.img, and the fastboot seems not working. Any ideas?

Click to expand...

this could be because the galaxy A51 wasnt built with fastboot, and the code to launch this option was just reused from a different device, or because something isnt connecting properly.
Hello, I have the same ... Android 11 (and currently 12) (from Frija). So it is not the fault of incorrect configuration or with connecting. Only something is wrong with this phone ...
I have this device and this solved it for me:
Enable OEM unlocking in developer settings
Shut down the phone
Hold volume up and volume down
Plug in a USB cable connected to a computer (the computer being turned on)
Keep holding
You're in download mode!
Side note: This might not work in USA or Canada, I am from europe and it works here. I have no idea if it works in another region. Also, you can't just flash a recovery.img on Samsung since there is no real "fastboot", you have to use download mode and Odin.
But I know how to enter download mode... Problem is Fastboot mode...
There is no fastboot mode on a modern Samsung device. If there is, it's fake and you cannot flash anything with it. As you can see even from Wikipedia, Odin is the Samsung replacement of fastboot.
So no fastboot, only download mode.
If a guide is saying to use fastboot, it is not compatible with Samsung.
If you would tell me why you specifically need fastboot, I'll be happy to tell you how you can do it with Odin, if possible.
Because I have Samsung Galaxy A51 5G (A516B) with new Android 12 and I can't do a root! Because I can't upload TWRP (custom recovery) because I haven't OEM unlock option in Deveoper Option. I tried trick with set back date by 7days but not succes. Everything I;ve metioned here - I did at my phone with Android 11.
And... I have read that I can turn this fu**ing OEM option by comend at ADB: fastboot oem unlock.
Phew ...
So this fastboot method is the last method to do a root with my phone.
Upload TWRP by Odin in download mode -ends red warning - of corse...
Have you any ideas?
I would be grateful for help...
I have read this fastboot method at:
How to Unlock Bootloader On Samsung Galaxy Phones [EASY GUIDE]
Are you looking for a Complete tutorial on How To Unlock Bootloader on Samsung Galaxy Phones? If yes, then you have come to the right place.
www.guidetoroot.com
Yeah, that guide is not relevant on any modern Samsung device. Besides, even if it was, which it isn't, you would first need to enable OEM unlocking from the Developer Settings.
But the fact that you don't have an option for OEM unlock is weird, since I have the exact same device model and it is there for me.
May I ask what is your region and is your phone locked to a telephone carrier?
My region is PLS - Poland. And not - phone is not locked. Have you the newest system Android 12?
Yes, I do. It's weird that there isn't even an option for you.
I'll try to come up with some new ideas if I have time...
I'll be glad for it...

You could try it. It might be risky, but it's the only option I personally can come up with right now.
I've tried this option but Odin stuck on "files verification". Any help?
have any of you encountered this problem?
And how did you solve it?
You can also try searching for combination firmware for your device online
