Hey guys, I had TWRP and rooted my Galaxy S7 long time ago and worked fine. From this morning it was on a bootloop and FRP locked out of nowhere. It doesn't even charge, keeps rebooting with the same message "Custom binary blocked by FRP lock"
I cannot get into TWRP/download mode. I tried every key combination with no luck. Can anybody help?
So, I managed to get it to download mode. If someone else also has the same issue, here is the way to solve it:
1. Vol+, home, power buttons
2. After a second or so take the finger off vol+ and press vol- while still holding home and power buttons
3. Let go of the power button
You won't succeed in your first attempt. But eventually you will get there. Immediately flash a stock rom after that and you will be good to go. Hope this helps someone.

Try to hold all buttons of your phone down for about 10 seconds and then your phone should restart itself.
Force your device to reboot by holding volume down, home button and power button at the same time. Hold the buttons down until the device reboots.
From then you can attempt to flash stock firmware via Odin and then making sure that you have enabled OEM unlock in developer options and that you have the correct TWRP for your device (Check MD5, to make sure it isn't corrupted)
Didn't help!

Hey! How did you manage to solve the problem? I'm having the same issue.
Hi everyone,
I followed the guide about the root for my S7 ITV. I've done everything step by step and flashed with odin the cf-autoroot.
When rebooted I had a blackscreen and and this error "bootloader exception", with the impossibility to enter in bootloader mode with the botton combination.
Found a way to return to downlaod mode and reflashed the stock rom.
Now my question is how to have root permissions.
I'd like to try again (I always rooted all my android devices and never had an error like that) but I'd like to understand what i did wrong before doing it again.
Thanks

And how did you get back into download mode, as you do not say?
Thank you
UPDATE:- I tried to root my new S7 and ended up with bootloader error.
In order to get back to download mode this was procedure.
When you get lovely green and red writing in error.
Press all 4 buttons, power, vol down, vol up and home, hold all til screen goes black, then straight away, remove JUST your finger off the vol down button.
This will boot you back into recovery mode.
Do not wipe, clear or reset as it will not work, due to your bootloader corrupt which will prevent your phone ever booting correctly.
Press System off and let phone power off,
Leave for approx 30 seconds.
Now Press Vol down, Home and power buttons and phone will boot into download mode.
I am downloading original firmware, the same one which was is currently on phone to save any issues.
I will then be able to freshly install firmware with odin and then read how to root again without trying to get the bootloader error again.
Best wishes
Hi everyone. i'm using S8+ G955N running Oreo. I wanted to get rid of shutter sound so i would install TWRP and flash new rom. The problem is when i shut down the phone, then i press and hold bixby + vol- + power button but it didn't go to download mode. The phone then boot into ROM normally. I have tried many times and removed its case but it still boot into lock screen. Any ideas for this case? Thank you
Sorry for my bad english
When you get to the splash screen ...Let go of the power button.
Hello
My stock A515F/DS received an OTA about 3 days ago. After it restarted to finish the update, it got stuck in the boot logo. It will reboot on itself from time to time, and I was able to reboot it manually by pressing vol down + power, but I can't get into recovery or donwload mode (by pressing vol up as soon as it reboots). The screen flickers for a moment, but it reboots again. We are under quarantine by federal law so I can't get my phone to samsung. Is there any way you guys know to flash it without going into recovery/download mode? I don't mind losing my data, everything is on my drive account, I just want my phone again
Thanks in advance
I think there is no way without entering in download mode or bootloader. Try with this:
When the phone is on, no matter which state, press Vol down + power until it reboots. As soon as the screen goes black, change to Vol. up+power. If this is successful, you can then select Reboot to bootloader to enter in download mode.
If this doesn't work, the next solution is waiting the end of quarantine

Hi i have gala y a51. Also.

Cant get into recovery mode .
Plz help
I need help urgently. I tried to change the splash screen of my Samsung Galaxy A51. I downloaded a custom param tar file, placed it in my downloads folder and used this command in adb shell to replace the older one. I did back up my old param. But there's no way I can restore it. Now, my phone when I try to start it. It doesn't even seem to turn on the screen anymore. I hear the phone vibrating every 2 seconds so I assume it keeps rebooting. I tried to enter download mode but I can't because samsung made it that you need to go into the recovery first, so I tried to go into the recovery but nope, it keeps vibrating and it's not responding to whatever I do. Is there still any hope for my phone? Thanks in advance.
Hello, I had this problem too. My phone also stopped booting into anything, even in TWRP.
For me, the resolve was to make the phone force reboot by holding power button and volume down, then immediately try to enter the downloading mode by holding volume buttons, when the screen turns off
and then you need to flash your device with your stock ROM
I understand you, that you cannot enter the recovery, but for me this method worked
I managed to solve it, the problem I had was that I was unable to boot into download mode. Because I have a samsung galaxy a51 and I did not know how to enter it. The last phone I had was a samsung galaxy s7 edge, back in the old days it was easy to enter download mode, just hold volume down, power button and home button. Now for some reason I need a cable connected to my computer and then hold volume up and down simultaneously. After I figured out how to enter download mode I flashed stock rom and phone worked again.
