Hello people, I'm just going to get straight into it... FRP blocked my custom binary on my Samsung Galaxy On5. I am new to FRP and I wasn't being careful when restoring a backup via TWRP. Now I can only boot into download mode and OEM Unlock is disabled from what i can tell. I've tried Odin i can kinda flash the AP file it doesn't work obviously but it does mark my system as official for some reason so FRP isn't triggered but then it tells me to use smart switch to restore it via emergency restore. I can also flash the CSC and CC back to get to square one. I've tried Smart Switch but i don't know my serial number to do the initialization i have an idea of what it might be since i do have a TWRP backup of my phone on my PC so shouldn't my serial be there? Any idea to fix my phone or is it fully bricked?

so i rooted my first android device about 6 hours ago went great. how ever i made a rookie mistake and turned off the oem unlock after I was finished now I'm stuck and fear i may have hard bricked my device, i used odin 3 with twrp 3.0.2 and installed the supersu even made backups using both twrp recovery and titanium backup. but when i rebooted my device im stuck in the boot loop with a red message stating custom binary blocked by frp lock. and recovery mode is not accessable, only option is download mode. ok so i tried to go back to the stock rom but i get custom binary(recover) blocked by frp lock. is there a solution here or did i prema brick my phone.
im not new to the modding process i have done a few other devices just never rooted a phone before today.
any ideas on what i should try next

ok so i was having an issue where i bricked my metropcs sm-g550t1 (galaxy on5) when i downloaded the stock rom for my phone i would get a sw mismatch D2 B1 error. the reason for this error is the update that came out in the beginning of 2017 changed the firmware version from PF1 to PL1. so if you are also having this problem when trying to unbrick your phone use the firmware for phone SM-G550T2 then use your twrp backup to unbrick but remember to turn the oem unlock on or you will brick your phone again
Hello,
Recently I have rooted my samsung galaxy J5 SM-J500F phone. Next I opened OEM and enabled USB debugging, and then flashed TWRP with Odin. All went well, made a full backup (i.e. all the options were selected). I have stored the files on my PC, and then foolishly closed the OEM and USB debugging. Some time after I restarted my phone and I was met with the "Custom Binary blocked by FRP" screen. I could not boot into recovery, the only screen accessible was the download screen. I have hunted for a few firmware files, tried to flash them all to no avail. They are either being blocked by the FRP, or the "secure check fail" error (when trying to flash the PIT). I would like to
a) Repair the phone (my personal files can be deleted, no need for me to keep anything)
b) Prevent this issue for recurring (perhaps by disabling this FRP permanently in some way if possible)
Thanks in advance.

https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572 That might be worth trying the OEM unlock needs to be left alone when it is unlocked and never touched again.
A friend of mine gave me a galaxy on7 (bricked) for repair. I downloaded the stock firmware and flashed it with odin. After the boot up, the phone started normally. However, the IMEI numbers were not there and the device was giving a drk error in stock recovery. I enabled the Developer Options, tried to toggle 'OEM Unlock' but it wouldn't turn on. I tried the date changing trick for OEM unlock but none of the software update part worked as there was a drk problem. Any ideas on how can I toggle the OEM unlock or fix the DRK problem in this non root state? I plan on rooting the phone and then repairing the IMEIs or simply restore the EFS back up files I found online.
Hi there,
I have a Samsung Galaxy Tab A6 (SM-T285) which I bought today. I followed this tutorial to install twrp, ultimately to root the device:
I can't even post links so sad. But the link was of **********.
Everything worked fine and I was able to boot and reboot fine. Until I signed in with my Google Account. After trying to reboot, I get a black screen with the Samsung logo and a text in red saying: Custom binary blocked by FRP Lock. I went back to the store and they advised me to install Samsung Smart Switch to try and restore. In the Smart Switch program I get an error saying that the device is not supported by Smart Switch.
I can get into download mode, not into any other mode. I can't get into recovery mode. The tablet doesn't start up at all. On the download mode it also says FRP Lock ON.
When I go back into ODIN and retry to install the from above TWRP image, it says operation failed.
Can anybody please advice? I am at a complete loss. Am I supposed to flash the original boot file? Where can I find that for my device? Will my tablet accept that, since ODIN didn't even want to flash my current TWRP image a second time?
P.S. I only read later that you are supposed to change the OEM setting. I didn't. Is that the cause of this issue, and if so, can I do something about it?
Thanks

Reinstall stock rom
Change OEM setting in Developer Options
Then you install TWRP - Turn off auto reboot in TWRP
After ODIN install, manually reboot to recovery.

Hi there,
I got an old man's S7 Edge (SM-G935F) and I'd like to help him rescuing his photos (he doesn't have a periodic backup but he learned from this now).
The phone did stuck at the boot screen. He didn't try to modify anything.
FRP Lock on unfortunately. Should be the latest Android.
I can enter the download mode (not the recovery) but no chance for TWRP b/c of FRP. Same error for an engineering recovery I found online.
AP SUREV: B:8 K:B S:7
So I got me two OEM firmware packages with Frija and try to reflash but it always stuck at flashing "boot.img" endlessly.
Also it got me to the "An error has occurred while updating the device software, Use the Emergency recovery function in the Smart Switch PC software." screen now.
(I have no code for Smart Switch recovery but I still can get into download mode using FRP Hijacker.)
Is the NAND most likely roasted and the only hope may be chipoff? Tried on different PCs with different cables.
Thanks,
Nico
Edit: I don't need a working device, decrypted dump would be enough.
Edit 2: When I skip the AP package (containing the "boot.img.lz4"), it stucks at flashing "RADIO" after a few percent.
