Edit: No one replied with a good answer so i reinstalled stock recovery while keeping root and turned off OEM Unblock and it bricked my device with "custom binary blocked by frp lock" and i am currently fixing it with Smart Switch initialization. Moral of the story: Never disable OEM Unlock
(A5 2016)
Does this happen after you turn off OEM Unlock because the recovery is not stock (TWRP is installed) or because the device is rooted or both?
If after rooting with https://forum.xda-developers.com/sa...overy-samsung-sm-a510f-fd-exynos7580-t3314399 i flash stock recovery and turn off OEM Unlock will i still get this message?
Thanks!
Please note that i had the "custom binary blocked by frp lock" error but i fixed it with Smart Switch initialization. I want to turn off OEM Unlock for security reasons
just flash previous firmware version which u have in your phone before frp lock.
nothing to worry its not bricked.
only ensure version u are going to flash is same as before , flash via odin and enjoy
I already did it, my question is that if i remove TWRP and install the stock recovery while keeping root, will disabling "OEM Unlock" show "custom binary blocked by frp lock"
Help
I am going through a similar enigma. I have S7 Edge. If I log in with Google and then turn down unlock on will I get custom binary error? Any help would be greatly appreciated.
@CrystalGTX
This is an old thread, but I am having the same problem; (stupidly) unchecked OEM Unlock. Reboot, and now I have "Custom binary blocked by FRP lock".
When you say "fixed it with Smart Switch initialization", does that essentially mean reflashing firmware?
And as a result, erasing all data?
I've read that flashing stock firmware can save the hardware, but I'm much more concerned about the data; I need my contacts, photos, txts, etc.
EDIT: Err, shoot. I see now this was posted by a Guest, so I doubt the OP is going to give me a response. Anyone else help?
Hi everybody

I have a working S7 edge oreo 8 phone that I can enable USB debugging and install twrp and take a nandroid backup. I recently bought an identical phone off e bay that I found is FRP locked so I cannot enable USB debugging. Is it possible to install twrp on the FRP locked phone without usb debugging enabled and then install the nandroid backup off the working phone to get around the frp lock? Alternatively if i enter recovery mode on the frp locked phone is it possible to install twrp using the sd card option? Any help would be appreciated
BUJ1 fw. I had previously rooted the device and it was working fine, then x days later found it wouldnt boot (teal screen with 'enrolled knox guard prevent flashing factory binary (vbmeta)' displayed) so I reflashed the stock binary. Now when I go into dev options, I cant get OEM unlock to appear (tried the date forward/back.. didnt work). Anyone know how I can fis that?
Additionally, in download mode the tab shows 'oem lock off (u)' and 'kg status normal', but when I try to flash the magisk modified ap file to root it, it fails almost at the end of the odin process with the 'enrolled knox guard prevent flashing factory binary (vbmeta)' error displayed on the download screen. Rebooting then boots back into the stock android. Is this likely to be linked to the owm unlock being unavailable in dev options even tho the device is showing oem lock is off?
