Cant boot my phone...Custom binary blocked by Reactivation Lock

Hi I have a big problem because since I tried to reboot to install an add-blocker, I can't go into recovery and I can't start my gt-n9005 anymore because following error message comes:
Custom binary blocked by Reactivation Lock.
SECURE FAIL: KERNEL
And when I want to flash something with odin in download mode following error message appears:
SECURE CHECK FAIL: Recovery
Please help me I don't know what to do. Thank's in advanced...

Could please someone help me?

Can you boot your phone? If you, can, you can go to settings and uncheck the reactivation lock..after that, you should be able to enter recovery normally.
Regards!

Try flash back your country firmware with correct CSC.
Try this it might help if that is the thing you did before - http://forum.xda-developers.com/showpost.php?p=46389503&postcount=2 scroll down to section mention
HELP! I flashed N9005XXUBMJ3_N9005OXABMJ1 and now I am stuck in download mode! What do I do?!
You are mostly going to trip the KNOX Warranty at this point.
Flash this AP N9005XXUBMJ3_N9005OXABMJ1_BTU_RECOVER.tar.md5 (2.05 GB) and this CSC N9005OXABMJ3_CSC.tar.md5 (38.0 MB)

Factory reset won't help, as Reactivation is blocking you if you had use different country CSC and you did it before you un-tick the Reactivation Lock.

I can't boot my phone and i can't boot recovery...i always get the message "Custom binary blocked by Reactivation Lock. Secure fail: Kernel" with a yellow alert triangle underneath, even if I normally try to boot my phone. And when I than press the power button the phone turns off again.
I tried to flash cwm with odin but that also failed.
So before i go downloading another firmware (i live in a dormatory and only have 10gb internet a month) do you really think that would work?

I had this exact problem recently and I booted by going into download mode and then pressing volume up to reboot. Somehow or other that would boot. Powering off and back on would always get that error that you are getting.

Thank you very much RP that let me boot and uncheck the lock. I had just installed Goo and put twrp on my device.

Hey guys.
Had the same problem with a similar message after Flashing the N3EchoeSlimV2.zip. (was running on Xnote V3 europeen firmware )
Custom binary blocked by Reactivation Lock.
SECURE FAIL: RECOVERY
Only way to boot, was the download mod
So i went back stock rom with Odin.
But i coudnt flash any Custom recovery or Cfroot. Many tries with différent Odin version.
I finally installed a recovery after took the battery off a couple of hours.
Sorry for my bad english

Same problem here with the slim version!
Anybody have an idea?

I had posted the solution here on a different thread but let me make it easier for you:
Solution.
1. download KIES 3 (for note 3)
2. Click tools>Firmware upgrade and initialization
3. Put phone into download mode (press Volume down+Home Button+Power Button and then volume up)
4. Connect your phone (it is OK if it is not recognized by KIES, just keep it connected)
5. Now do as it says by typing in your Phone model number (check the battery compartment).
6. Type in the S/N.
7. Let it do its business and download the firmware.
8. Once firmware is downloaded, It will start communicating with the phone.
9. You can see a blue progress line on the screen under the android guy.
10. Let it finish and restart.
DONE! you are back to stock..
NOTE: This doesnt make your KNOX warranty 0x0 if it is already 0x1.
Click Thanks if it helped!!

Calm down guys
What I did was enter into download mode like rp1790 suggested and maybe he did a typing error. When in download mode press down to restart the phone. It bypassed the custom binary block error and booted as normal.

This doesn't work if you install a firmware with the new bootloaders... You CAN'T flash an older bootloader over the new one. It just sends you into a bootloop....
And thats before you include the re-activation lock error...

I have also just encountered the same error as the OP, however the above method doesn't work for me, kies 3 gives me an unknown error (i.e. it doesn't say what error) and just fails.
Same deal as me, was using X-Note and installed the add blocker, rebooted, BAM.
Any help is going to be greatly appreciated!
:crying:

yop
i've the same problem and a full wipe fix it

Just got it fixed
I recently had this problem.
I've read from this thread to boot into download mode and just cancel. It will boot normally after that. I'll never reactivate it again.

What did you do prior to this? It looks like you flashed a custom recovery but Knox is terminating the boot process.

Have you tried to odin back to stock?
Sent from my Galaxy Note 3 ?

Trying to use Odin - downloading a stock ROM now.

No. You must get into download/Odin mode by pressing volume down + home + power simultaneously, then launch Odin, then connect phone to computer.

If you have a Verizon retail version of the Note 3, you can not use Clockworkmod recovery. Because your bootloader is locked. You can only use Hashcode's Safestrap (in the Development section).

Which means you must be rooted first, then install Safestrap, which is a modified TWRP recovery. You can thank Verizon for that bullsh!t

Got me back up and running.

Flash PIT - this will fix it
You need to flash the PIT with ODIN, latest version (3.09, I believe). Google for a download mirror that hosts the PIT for whichever type of note 3 you have, then flash it with odin (should work while in the invalid software screen). Then, if it doesn't reboot, just remove the battery and unplug that sucka. When it reboots, it should go back to download mode or just regular bootup. I recommend setting up adb, which makes it much easier to put the phone into whatever mode you desire with a simple dos command.

got out of it
this happened to me last night, I went into Odin mode "home, volume down, power button" instead of selecting odin mode from that menu I selected "reboot phone" (or something to that effect) My note 3 restarted......PHEW...... hope this helps someone

ok so I once got to the point to where I could not but factory reset my phone and so I did settings > backup and restore > factory reset > YES I'M SURE!!! then my phone when into recovery mode as it should normally only to tell me that it could not enter recovery. Verizon's fault and now I cant access my recovery mode. is there a way to get back into it so I can finally flash a new rom. oh I had figured out how to get out of the boot loop thing by entering download mode and canceling. but it would be nice to be able to mess with this beast of a phone. please help me. I don't want to do something I wasn't supposed to. im not sure want to do with klms agent deals with knox right?

[Q] Galaxy S4 i9505 Bricked - No Recovery Mode - Stuck in Bootloop

Guys,
I was using the Cyanogenmod 11 for about 2 weeks and I always got the "kernel is not seandroid enforcing" message and the phone always booted up fine 90% of the times. Today I got the message saying that there was a new version of the firmware and I clicked ok for the phone to restart and begin the update process.
After that, I was stuck in the "kernel is not seandroid enforcing" message no matter what I did.
I entered the recovery mode and wiped the cache partition to see if that solved the problem. After this, I'm not able to access the recovery mode anymore and the phone is stuck on the samsung logo.
So I put it in download mode, opened Odin (It recognized the phone just fine) and flashed the original firmware in order to unbrick the phone. Got a PASS on Odin and I was still stuck on bootloop with no recovery mode.
Tried flash it again with the pit file (thought it would fix the partition) and the problem stills perssists.
I tried to run the Cyanogenmod installer and it doesn't recognize the phone anymore, saying the model is not compatible. Odin still recognizes the phone as always when I put it in download mode.
Any ideas?
Have I lost the phone ?
Thanks in advance for the help.
Best Regards

Hi,
When you run the stock firmware through odin , you must wipe the cache an data before and after the flash.
Did you do that?

Hi,
Are you sure you are trying to access it correctly?
Try holding the power button + volume up.
When the blue writing comes up , let go of all the buttons , and tap volume down.
If that still does not work , install the stock firmware again , and see if you can then get back to recovery mode.

Already did that, still no sucess. It enters the download mode normally but when I try to enter the recovery mode the blue text appears and then the screen goes black and the phone tries to boot and gets stuck on the samsung logo.

And yes I'm trying to acess it correctly.

Remove battery, wait 10 seconds replace battery and
hold down the volume down+power+home key at the
same time. Then the phone will go into download mode.

I have 4 sprint Note 3's I rooted with CWM for all 4 but one is "stuck" at recovery like this any time I turn it on it always tries to boot into recovery and gets stuck.
I can get into download mode. will cf auto root fix this? (trying to avoid a full odin restore)
the only thing different about this sprint note 3 that I am aware of is that its flashed to boost (if that matters it should not matter)
the other 3 went flawlessly. yes I tried to odin the cwm root a second time no change.

Thanks!!!
Thanks for the link. Just unboxed the note 3 (sprint) with version 4.3 and followed qbking77 and it was stuck on that same screen (tried it 3 times).
Your link saved me. :good::good::good:
I wonder why qbking's didn't work ... it always has in the past.

Why didn't you use the specific file for your device (Note 3 Sprint): http://download.chainfire.eu/362/CF-Root/CF-Auto-Root/CF-Auto-Root-hltespr-hltespr-smn900p.zip

thought I was...
Maybe I'm getting dumber, or maybe it's getting more confusing to root. Seems like there's a crap load of how to root this device pages and it takes a long time to figure out which one actually works. Then once I find it, I'm faced with dead links to the downloads.

I read on many posts and comments that everyone is able to boot in download mode. My Note 3 just stuck on recovery boot and I can't get it to boot in download mode. I tried all of the suggestions about pressing three buttons, removing battery etc.
Does anyone know solution for when you can't get into download mode?
Thanks

Do you have access to a USB jig?

i know this thread is old....but sometimes i have to access download mode, and then chose cancel in order for it to boot. usually from recovery when i tap reboot system, it brings me back to recovery. so i have to pull the battery and button combo to download mode then cancel. does this issue have any familiarity?

Someone please help I have a Samsung note edge that I just reset through the menu settings backup and reset option and phone turned off but did not fully come back on its just sitting on black Samsung Screen and on top left corner it says recovery booting set warranty bit : recovery in blue and yellow letters and I am able to got into the download screen but I press volume down just to cancel and reboot and stars coming on but gose back to same black Samung screen. Like i said I did not try rooting it or any such thing.

Wrong forum this is not EDGE model .
Download mode and flash stock rom through Odin is generic advice .

"Recovery Booting" Bootloop fix
A few months ago, my rooted Galaxy Note 3 (sm-n900t) was force closing and freezing my apps often. So I decided to boot into recovery to clear device cache. The 'recovery booting' would appear on the screen with the logo, but after 7 seconds it would reboot normally instead of opening recovery(I had version 3.2.3.0). So I did reboot recovery with Rom Toolbox and it began bootlooping with the message:
Recovery Booting....
Set Warranty Bit : recovery
It wouldn't boot normally, in recovery or download mode.
STEPS TO FIX:
1.) Let phone Bootloop until completely dead
2.) On PC downloaded (2.8.7.0) twrp file for device from twrp.me/devices
3.) Press and hold volume down + home + power until phone reboots into download mode.
4.) Plug device into PC USB where drivers are loaded.
5.) Start Odin or Samsung Tool z3x flashing tab
6.) Load twrp in AP or PDA section and flash
7.) Phone should reboot normally!

flash stock firmware.
go to sammobile.com
Search for grand 2 firmware
then download it.
The firmware must base on your country.
after that flash using odin.
after complete. Remove battery then insert it again.
go to recovery
wipe everything
then reboot system
wait about 10 minutes
congrats your phone is normal again

Solution to your problem:
You will need to download the NK1 version of kitkat 4.4.2 stock firmware.
1) install samsung kies or samsung usb drivers so that your PC will detect your phone.
2) Switchoff your phone first and put it in download mode by pressing volume down and home button and power button at the same time.
3) connect your phone to your PC through the usb cable and start odin. (The com port turns blue in odin which means phone is detected).
4) In odin, check the "Nand erase all" in the checkbox and then click on "AP" buttion and select the "G7102DDUBNK1_G7102ODDBNK1_G7102DDUBNK1_HOME.tar" file.
5) Click the start button and wait for 5 mins till the OS is installed.
6) After installation, on your phone it might show 'memory damaged' and 'erase memory'. Don't worry, nothing is damaged or serious, just click to reset and everything will be fine.
7) Done!
I have provided the NK1 version link to you from my google drive account:
https://drive.google.com/folderview...03NF9WUzJLTHVSVnkzWWN5aFVQSzVOS28&usp=sharing
(Please hit thanks if I helped you)

Thanks guys
Problem solved and it is working now :fingers-crossed:

I have this same problem and I downloaded the above file and followed the instructions accordingly, after flashing it is still stuck at REBOOTING TO RECOVERY for about one hour now.I guessing it might be related to hardware.

Which firmware were you on before the first boot loop? Flash that firmware, and don't forget to pull the battery afterwards.
(Don't hit thanks, hit the phone on a pillow/bed of you think its hardware related).

Solution to your problem:
You will need to download the NK1 version of kitkat 4.4.2 stock firmware.
1) install samsung kies or samsung usb drivers so that your PC will detect your phone.
2) Switchoff your phone first and put it in download mode by pressing volume down and home button and power button at the same time.
3) connect your phone to your PC through the usb cable and start odin. (The com port turns blue in odin which means phone is detected).
4) In odin, check the "Nand erase all" in the checkbox and then click on "AP" buttion and select the "G7102DDUBNK1_G7102ODDBNK1_G7102DDUBNK1_HOME.tar" file.
5) Click the start button and wait for 5 mins till the OS is installed.
6) After installation, on your phone it might show 'memory damaged' and 'erase memory'. Don't worry, nothing is damaged or serious, just click to reset and everything will be fine.
7) Done!
I have provided the NK1 version link to you from my google drive account:
