TWRP will not work - Sprint Samsung Galaxy S7 Edge Questions & Answers

I tried flashing TWRP via the app (I am rooted) and when I go to reboot into the custom recovery, it says "Custom binary blocked by SECURE BOOT (boot.img)."
and
"Security Error: This phone has been flashed with unauthorized software & is locked. Call your phone operator for additional support."
I just want TWRP to flash some kernels, a custom ROM, etc. I am happy with root but I wanted TWRP.
I'm on the US S7 Edge Snapdragon variant QF3.
Can anyone help?
Thanks!

Your bootloader is locked and as such, you can not flash a custom recovery.

Purchased a Note3, stuck on Custom ROM boot screen

Haven't rooted a phone in a little but am generally pretty savvy. I can get into recovery, tried restoring factory settings and clearing cache, same result unfortunately. I tried running an Odin .exe I found in another thread but it just opens and closes.. :/
When in download mode, product name: SMN900V, System Status: Custom
Knox Kernel Lock: 0x0, Knox Warranty Void: 0x0, Qualcomm Secureboot: Enable (CSB), RP SWREV: S1, T1, A3, P1
Write Protection: Enable, UDC START
Any help anyone can offer or provide a working rom or flashable file to get me booted would be most appreciated! No idea what ROM or Android version he put on this thing (purchased from Swappa).
TIA!!
Re download Odin and tar file. Have you gotten Odin to flash anything or does it fail or do you mean Odin itself isn't working? It sounds like you didn't extract Odin files and just opened it.

I was able to flash a Verizon firmware (thru Odin) and get it booted but I don't have root (seller claimed he did beforehand). Sounds like I should start with unlocking bootloader or root first? Thanks for the response man, I appreciate all the help I can get!

Start with the root first. Can't unlock the bootloader without it.
Awesome is there a one click by chance or is it complicated?

I had installed jasmine rom and ended up having problems with certain apps not working due to the modified framework he was using. I used odin to flash the new OB6 & pit (returns to locked boot loader with stock lollipop rom). I took the OTA to OF1, then used the yemen 1 click root. At this point the only issue I have is trying to get a customer bootloader installed. The TWRP version 3.0.2-0 just leaves me stuck at boot loader and I had to reinstall the pit file to get phone to boot again. Hope that helps you. I like stock rom but am trying to get native tether to work, without customer bootloader I can't flash anything.
I just got note3 Verizon, I rooted it couple days ago. I am on tmobile, so far everything works with stock lollipop except hotspot. Contemplating on unlocking boot loader at the moment.

I was fooling around with flashing custom recoveries from within a rooted ROM today, and found something useful - when I "got stuck at bootloader" because TWRP failed to boot. So long as the main ROM is still bootable and is rooted, you can clear the "always tries to boot the recovery" behavior the following way:
1) Pull the battery (and plug back in after a couple seconds)
2) Vol-Down+Home+Power (as if you are trying to enter Download mode)
3) When you get the Custom ROM Warning menu, choose Cancel (not Continue)
This clears the BCB (Boot Communication Block) in eMMC and the phone will thereafter attempt to boot normally, rather than continuing to try to boot the recovery again. The sequence #2-3 does not work if you don't start by pulling the battery - if you soft-boot by holding the Power button down (~ 15 seconds), the phone will always attempt to boot the (broken) recovery, whether you enter Odin mode or Cancel.
Well, that's the way my phone behaves at this moment. (I am using a older bootloader however - it is always possible that this is a bootloader behavior that changed in later versions). Anyway - if you get "stuck" again, this could save you some labor, rather than having to go back to Odin, flash everything, and re-root.
Having said that, I'm not sure what you would use as alternative custom recovery. You could do something like pull just the stock kernel from the OF1 and re-pack it into your own customization of TWRP to see if that changes anything. Thing is, I could have sworn I saw a report from someone who said they are using TWRP 3.0.2 with the OF1 bootloader successfully.
Are you using "twrp-3.0.2-0-hlte.img" ?

I get a different kind of stuck, I'm not going to try it again but it said the phone has detected software that is not authorized or something along those lines. I cannot just pull battery as it just repeats over and over. I actually do not ever get to enter any recoveries at all, it automatically detects that's it's not the original bootloader and tells me such. anyways, I had to reload the image and take the OF1 update again... all is working back to normal.
I had used "twrp-3.0.2-0-hltevzw-4.4.img" from the twrp manager app, flashed via app, restarted to end up having the error message immediately on bootup of device... no recoveries or anything could load. I would have to assume the 4.4 means kk version and that's why it didn't work?

Hmmm. Maybe I was reading something into your post that wasn't there. I assumed that you had also performed the retail-to-dev edition CID change "unlock" after you gained root on OF1. Is that wrong - did you simply flash a recovery after getting root?
In my case I flashed a non-bootable TWRP (dd of=/dev/block/mmcblk0p15...) onto the recovery; doing this tripped my Knox Warranty flag, but otherwise the bootloader didn't complain about unauthorized software. After figuring out how to clear the "always try to boot the recovery" near-disaster, I used a 2.8.x TWRP series custom recovery successfully (In addition to flashing the stock recovery back into place and verifying that it still worked) But this is on a truly ancient bootloader (MJ7), so maybe all bets are off about expecting later bootloaders to behave in this same fashion.
Still, the point of developer edition functionality is to allow for custom boot (& recovery) partitions, so it's surprising that you were getting warnings like that if your phone was in developer mode.
@santas16
Hey. For what it's worth, I was able to boot twrp-3.0.2-hltevzw-4.3.img from my SM-N900V ... with a MJ7 bootloader!
But not the hltevzw-4.4.img. (That could be due to the old bootloader however, I don't know for sure)
Note that my phone has the retail-to-deved CID change that puts it into developer mode. (I used @donc113 's executable with adb)
This allows unsigned boot or recovery partitions to proceed to load/execute, but it will burn your Knox Warranty flag (which is unimportant to me at this point). I think that is actually the expected behavior when the phone is in developer mode.
I've been flashing all sorts of recoveries without worrying whether they will boot or not (as I know I can get back into the rooted ROM to flash into place a working version)**
Probably the best advice about not getting stuck in the "continually tries to re-enter the recovery" mode is to NOT use "reboot to recovery" methods (in Safestrap, other recoveries, or root-privileged Apps (flashfire?)), but to always shut the phone down to a powered-off state, and just use the three-button startup method (Vol-Up+Home+Power) to enter the recovery. That way nothing is being written into the BCB that will make it want to loop back to a failed recovery.
cheers
** what was interesting is that I could successfully boot any of the MI9, MJ7, MJE stock recoveries on my MJ7 phone. Moreover, the bootloader would not pop up the yellow "Set Warranty Bit: recovery" message right before they loaded. The NC4 recovery would not boot to a menu, but it also did not present a "Set Warranty Bit: recovery" message. I presume this means that the boot layer is not looking for exact version matches, but rather just checking that the Samsung signing operation is correct. I could not boot OB6 or OF1 recoveries; somewhat curiously though, these attempts *would* throw the "Set Warranty Bit: recovery" error message even though they are validly signed Samsung recoveries. I don't know if it is a reasonable hypothesis, but I think that indicates that Samsung may have altered the details of their signing verification method someplace between NC4 and OB6 so that earlier bootloaders fail this check. Ugh. As if there weren't enough details already.
If your bootloader is still 0F1 then download flashify from Google and hit recovery and tap top twrp.. Your all set...sounds like a lot of craziness for nothing.

If you get the " not authorized or something along those lines" error, it means you're not unlocked.

Asus Zenfone Max (ZC550KL, Z010D), Android M, Unable To Unlock Bootloader

Hi there! I have this question which I'd love to have answered because I've been on this issue for around 2 days straight.
Long story short:
Tried to flash custom recovery using fastboot, didn't work because bootloader locked
Kept on trying the unlocker apps, none of them even installed fully (THIS WAS WHEN I WAS STILL ON LOLLIPOP)
Somehow, at some point, I just randomly rebooted and BOOM THERE WAS TWRP (Sorry, I don't remember how exactly I managed that. As far as I remember, I was only using fastboot and nothing else)
Flashed CM 14.1 unofficial, device gave an error message regarding boot.img (something like "could not load boot.img"
Used stock ROM to flash OTA Android 6.1
Now the Asus unlocker app downloads but on reboot it says "error: unlock fail !!!"
Obviously, fastboot is unable to flash a recovery right now. I tried ignoring the error message and rebooting to recovery to stop the device from loading the stock recovery again but the device still loads the stock recovery.
I'm really tired
P.S: NO, there is no Enable OEM option in my Developer Options menu and YES, I have all the drivers necessary.
Did you get anywhere with this? I have a similar problem except that I couldn't flash Android 6.1 because the vendor had flashed WW 5.0.2 on a CN phone without also updating the CN recovery to WW. So the update failed its consistency check.
I've got TWRP on there now, but can't unlock the bootloader in 5.0.2 - I think this is why TWRP can't flash anything. It can't see the update files, won't switch to external SD, etc. .
I also found and tried flashing a WW recovery but that didn't work either. I'm wondering now if I got the 615 software by mistake.

Unable to flash twrp recovery

My device is rooted but when igo to put custom recovery odin says secure boot (recovery) fail or auth fail. What am idoing wrong?
Maybe cause you can't? I'm not trying to sound like a troll, but you can't do that.
All I'm gonna say is more research is needed, if you don't have an international version you won't be able to

As the other reply wrote, you can't flash TWRP recovery onto the Verizon S7 because the bootloader is locked. Can't be done. You need to check the guides in this forum to find out how to flash the few ROMs available.

Bricked Note Trying to flash TWRP -Set Warranty Bit: Kernel

Hello all! I need some help with my Note 3 Sm n900p
I am in root (used win10 and kingo root for this) with absolute success.
Next, I followed this guide on Youtube: watch?v=4LyG5KW5jpQ
Upon flashing the TWRP .img file and rebooting I am stuck on the Galaxy Note 3 startup screen with the message "Set Warranty Bit: Kernel" above it. It wouldn't allow me to shut the phone down, but I was able to reboot into recovery mode and factory reset/wipe the data partition.
It still will not boot or do anything beyond that same splash screen. I removed the battery as the phone will not shut down.
I don't know much about flashing custom ROMs, I was attempting to install TWRP so that I could flash Lineage OS 15.1 without using ODIN, without using a computer. Please help. I can't get it to boot at all as it stands and I'm worried I've bricked it permanently
Usual is wrong TWRP flashed.
What did you use to flash this youtube TWRP ??
As you are posting in a forum not for your phone its 99% a file for a different model .
Suggest you post in the forum for your model .

Did you unlock the phone's bootloader? I believe Sprint phones come with locked bootloaders.

Any root method for SM-J727T1 with J727T1UVS6BSI2 (TMK) Baseband version?

As the title says, my device is a SM-J727T1 with J727T1UVS6BSI2 (TMK) Baseband version, and Android 8.1.0.
I tried to root my device with TWRP and Magisk, but during the Download Odin process it throws an error "secure check fail: (recovery)". I have the Samsung USB Drivers and USB Debugging activated, but I can't activate the "OEM Unlock", because that option is missing in the Developer Options. There are some guides that requires fastboot mode, but this device doesn't have fastboot mode, only the Download Mode.
Then, I suppose that the bootloader is still locked. But I can't unlock it. So I cannot root with recovery mode, nor with CF Auto Root via Odin. I also tried to root it with apps like Kingroot (Stuck at 1%), One Click Root (Doesn't have support for this device), and some others with similar results.
My objective is to root the device and flash the TWRP recovery with its official app, Flashify, Mobile Uncle Tools, or Safestrap app. After that, install a custom ROM. In the Resurrection Remix official page it gives a official version to the on7xelte device, which I think is Galaxy J7 Prime. Is my device compatible or not?
Try to flash u4 boot if its pass the you're able to root, otherwise don't waste your time
