Root attempt fail, "kernel is not Seandroid" bootloop. - Samsung Galaxy S7 Edge Questions and Answers

Bought a Galaxy S7 Edge today from a coworker, SM-G935F, Verizon variant (as far as I know. She bought it brand new and used it on Verizon.) First thing I tried to do was root it using this method -- https://theunlockr.com/root-samsung-galaxy-s7-s7-edge/
(basically used Odin to flash Samsung_G935x_QC_Rooted_BOOT.TAR)
Got a "Pass!" message in Odin, rebooted the phone.
Was greeted with a pretty red-colored message on the top left, "kernel is not Seandroid" followed by a continuous bootloop. Would automatically shut off on its own, etc. Had to boot into recovery to actually power it off. (Still stock recovery, by the way)
Anyway. Googled the error, didn't seem like a big deal with so many results and "Solved" also being prominant. Tried to revert back to the stock firmware and got this in Odin's log:
<ID:0/003> Re-Partition operation failed.
Came across another post suggesting to un-tick the "re-partition" option in Odin, which it already was/is. Now I'm kind of lost on what to do. Came across one thread suggesting that the firmware on my device doesn't match the one that I downloaded which.. I have no idea how to check that given I'm unable to even boot the device. I do recall seeing 2017 briefly when scrolling through the build/kernel section, possibly December 2017 if my memory serves me correctly.
Another thread suggested something about flashing a .pit file.
Does anyone know I how I can get this back up and running? Preferably rooted?
Thanks much in advance!

[Q] Reatail mode - Please help!

Hi! I have got a Samsung galaxy s5, locked in retail mode. And at first I didn't mind, But then I've rerealised that I can barely use the phone and this annoying video pops up as soon as I lock the phone. So I started to try to fix it. I've used this "philz" thing (I later realised that it would only take me to another recovery boot screen. Any way to remove it?) , and I've used the admin code in the Samsung retail app to deactivate the factory reset. And then I tried flashing with Odin. It was the first time I ever did that, so I didn't really know what to do. I got my phone into download mode, and that blue box in Odin, well, turned blue. And then I dodownloadeddownloaded the firmware from sammobile.com. I downloaded it for SM-G900F. I understood that that's probably the version I should use, because I live in Europe. Btw, the phone is made in Korea, and has probably never been used in a cellular net before, if that can affect which firmware I should download? Anyway, I picked the MD5 file and then Odin were freezing in a couple of minutes. But later it worked, for a bit. It says "setup connection" and then it says "Write operation failed" and then "All threads done. ( 1 failed / 0 succeeded ). This is how far as I can go. What should I do? I must do something wrong, but I really want to figure this out! Thanks!
Are you sure the phone is a G900F, since you say it's from Korea, it may be a K, L, or S model, in which case the F firmware is probably the wrong one.

Samsung Galaxy SM-G928X stuck on startup screen!

I have been trawling the internet for literally hours.
This is my final hope before I get really desperate with this device.
I bought a Samsung Galaxy Edge+ online as a demo unit so I could use it as a glorified tablet,
since it was a demo unit it had demo software which I tried to remove using the 5444 password
trick on the retail software to no avail. So I decided to root the phone using Odin and the
SM-G928 F/I/C/K/S software as i couldn't find the particular software for this phone anywhere.
This worked but every time I booted the phone it would give me the 'KERNEL IS NOT SEANDROID ENFORCING'
on the top left of the device which I promptly ignored and continued to use the device, I downloaded
root check which said my device was rooted and then I downloaded system app uninstaller to try remove all the trial
software, which unfortunately didn't work. I then attempted a hard reset, which also didn't work and just
rebooted the device, finally i decided to download Flashify and TWRP recovery to try and delete the trial software
from there. At this point I was just messing around with the phone when I noticed a thread that said i needed
titanium backup to fully delete the software, so i rebooted the phone and it has been stuck on the bootup screen
ever since, I have tried several methods to get it to work including re-flashing the software onto it,
(the SM-G928F one I mean) but i simply cannot find the correct one for my device.
Any help would be greatly appreciated :good::good::good::good:
The device is running 5.1.1
I am not sure of the kernel or anything like that as I am quite noobish.

First thing to do is to get into STOCK recovery and do a "Factory Data Reset"
or you can boot the phone up and go into "Settings>Backup and Reset" and
select "Factory data reset".
After doing that odin flash the proper S6 Edge+ Lollipop 5.1.1 or the new Marshmallow 6.0 firmware.
You can see the exact model of your G928 phone by going into settings and scroll down to "about"
there you will find the specific model of your phone.
Be sure to ONLY odin flash the correct firmware for your phone's model.
Once you do all the above you will no longer see:
'KERNEL IS NOT SEANDROID ENFORCING'
The only reason you see that is because the phone is rooted.
After odin flashing the proper firmware your phone will no longer be rooted
unless you root the phone again.
Good luck,
Have a great day!

I can't boot the phone up, if I could I would, I can't find the software for this particular model, which is aforementioned SM-G928X,
If you could help me with that, I would appreciate it. The phone is stuck on the Saumsung boot up, it doesn't actually boot up into
the lock screen so I can't do anything with it, if you could help me with link to the SM-G928X firmware that I could use in ODIN
that would be greatly appreciated cause the phone is a paper weight at this point.
I had a moment of madness and decided to do what you said anyway, and I can't factory reset the phone from the recovery menu as it says
its due to security policies or something of that nature, which again I mentioned in the initial thread.
Also to clarify, I can't flash my own firmware because I can't find the firmware anywhere on the internet.

I have done a bit of research on your G928X device and I think you are in luck.
Check out this link carefully http://pdadb.net/index.php?m=specs&id=8759&c=samsung_sm-g928x_galaxy_s6_edgeplus_lte-a_samsung_zen
and you will see that the firmware in your phone is identical to many other G928 firmwares as you will see in that link.
Odin flashing any of the ZEN firmwares in that link cannot brick your phone, the worse thing that can happen is that it will not
work. (just like it's not working for you right now).
I would go a head and odin flash the S6 Edge+ G928T firmware which is also the ZEN baseband firmware, there are many S6 Edge+ phones
using the exact same firmware. All Samsung S6 Edge+ firmwares contain the modem but not all of them will be compatible with your
carrier but at least you will be able to boot your phone normally without getting stuck on boot screen or bootlooping to start with.
You can get the G928T firmware from http://sammobile.com OR
https://www.androidfilehost.com/?fid=24499762636004597 (fast download)
Good luck,
Have a great day!

Recovering from FRP Lock, did I brick my phone?

Hi all,
New user here, not much experience rooting or messing with firmware for phones. I was following the guide on how to flash the SM-935U firmware to the verizon model of the Galaxy S7 Edge, and may have bricked my phone. Here's what I did.
Followed the guide to the letter.
Powered off phone, booted to Download mode
Fired up Odin, selected the SM-935U firmware files, and clicked start.
It gave me an Auth error, which research revealed means that I forgot to turn off Reactivation Lock. I figured, "Fine, I'll just disable it. However, I can't get the phone to boot again. Every time I leave download mode, it boots into Android Recovery, where, no matter what I do, it just reboots into Android Recovery. I can't Wipe anything because it can't mount /system - probably due to Reactivation Lock?
I've been research and researching ways around this, and everything I find just points back to flashing it with the stock firmware. But then I read that you can't even do that if Reactivation lock is on, because Odin will still fail with the Auth error. So, I can only get it to boot to recovery mode, and I can't flash it with anything?
I did read somewhere that if I choose to wipe the phone's EFS with Odin that it should override activation lock, but then it clears the phones IMEI, which is an even bigger mess, isn't it?
I feel like I have to be missing something... since it never did the wipe, why is it that I can't get past the recovery mode. Shouldn't I still be able to get into the system somehow?
Does Anyone have any thoughts or suggestions for me? I'd really like to not be stuck with a permanently bricked S7 edge if at all possible....
Solved
Just wanted to post this to help anyone else who might have this issue. Turns out that you can flash the stock firmware, as long as you're flashing at least the same version or newer of the stock firmware as what the phone was running prior to getting stuck in recovery mode. It shows you what version it was running in the recovery mode at the top.
So for me, I googled the exact firmware version that recovery mode said the phone was running, downloaded it, flashed it with ODIN, and it worked just fine. Had to choose to wipe with the recovery mode after I flashed it, but then it booted like normal. - Then I enabled OEM unlocking under the developer menu, and tried flashing the U firmware again with ODIN, and it still failed with the auth error. Huh.
Turns out (maybe I wasn't doing it right or something) that you can't flash older versions of the firmware to the phone. But, as long as OEM unlocking is enabled, you can flash the U (unlocked) version of the current firmware to the phone and it will take just fine. Hint: I was able to determine the "version" number by looking at the last 4-5 characters of the build number... the verizon version I was running for my SM-935V was: VZW-G935VVRU4API3 - So I googled the API3 firmware and found the U (unlocked) version for my carrier (I happen to be using T-Mobile) on this site: https://samsung-firmware.org/model/SM-G935U/ and found the zip file name which was TMB-G935UUEU4API3-20161011161050.zip, googled that, got the rapidgator link, downloaded it, and that flashed just fine to the phone, and now my T-Mobile SIM works perfectly in what was previously the SM-935V, which now identifies as an SM-935U in settings. It's beautiful.
Also, you need the PIT file, but I was able to use the PIT file for the phone model number (again, found at the top of the android recovery menu), which for my phone was: HERO2QLTE_USA_VZW.pit (googled that and got it off androidfilehost) - I was able to use that PIT file for the T-Mobile U version of the firmware and it worked just fine.
Hope this helps someone.

Failed Root -- Bricked Bootloop SM-G930A

I'm completely at a loss at this point.
I attempted to root my Samsung S7 (AT&T) with Odin, and received an error. This is my first time ever rooting a phone, and I am generally oblivious to this kind of stuff. I disconnected the phone, and it began bootloop. I loaded it into download mode, and attempted to reset to stock. However, I have had endless issues trying to flash the stock firmware to my phone. At one point I unplugged the device once again, and I received the "use Emergency Restore" error screen. I tried to restore with Smart Switch, but I was not able to access my S/N (box is nowhere to be found, managed to find a S/N on Samsung's website since I registered it but Smart Switch wouldn't take it). So, I figured trying to restore with Odin was my last option. I have tried at least 3 different Odin versions, both modified and not, and not a single one of them has worked. I've received Complete(write) errors, Model Dispatch Fail errors, and Re-Partition errors. I've tried about 3 different firmware files as well, and while I think the one I have right now is most recent, none of them seem to be working. I thought maybe an issue I was encountering was that USB debugging or whatever it's called was disabled, but I have no way of telling because I cannot boot my phone.
I was fiddling around with all of this from 11pm to 6am last night, and picked it back up as soon as I woke up. I've been freaking out about this for hours.
I feel like I'm running in circles here. I don't understand what I'm doing wrong. I'm recovery bootlooped as well. The only thing I can boot is download mode.
I wasn't very cautious with this process, and I am completely unfamiliar with most lingo on these forums and the whole process in general. I really regret trying to do this. So -- is there anything else I can try to do to fix it? Or is my phone bricked for good??? I'm endlessly frustrated and have honestly felt like crying a few times over this. I shouldn't have messed with something I know nothing about. :crying:
I thank you for your patience in dealing with me as a beginner + appreciate any help you're able to give.
Cheers.

If you can at least get into download mode, then simply flash it with the latest STOCK firmware for your particular model.
That will bring it back to life, and you can attempt rooting it again, if you dare

Did you finally recover your phone? I'm in the same problem here since yesterday and feel your frustration right now. My phone is a Samsung S7 model SM-G930A from AT&T.
I found this thread https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039 and I following the "Return to stock part", now downloading the firmware. Hope it helps.
I'm stucked in the blue screen "An error ocurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". Of course I try the Smart Switch but says that my model is not supported!
How can you recovered the download mode? I press the on/off button for some seconds and the screen turn of, but it turn on again with the freaking blue screen "An error ocurred while updating the device software. ...". I tried all the possible button combinations.
Thanks and good luck.
Stock firmware
Make sure when you go into download mode and flash that plugging the phone in is the LAST thing you do. I.e. plug phone in only after it is in download mode and only after you open Odin. Secondly, make sure you flash the STOCK firmware, as in Android Marshmallow v6.0.1 . Additonally, make sure that the re-partition option is NOT ticked, and also you might want to try turning off auto-reboot, and just hold the power button after unplugging once the status bar is all the way full and Odin says complete. Also, you need to make absolutely sure that you're getting the firmware for your exact device. I.e. SM-G930A stock firmware is NOT compatible with SM-G930F models. You could also try reinstalling the Samsung drivers. I just flashed to stock firmware then updated back to Nougat yesterday, mostly without a hitch by following these guidelines. There is a download page on rootmygalaxy with all the stock firmwares, that's what I used (I'd link but I just registered here). There is a very helpful guide on droidviews about how to update to Nougat 7.0 once you have finished flashing the stock firmware.
If I were you, I would just avoid rooting altogether. Rooting for me caused very bad performance and battery life, and it wasn't really worth the trouble. Sure, getting in-app-purchases for free was nice but I never tried flashing a custom ROM or anything because most of the stories I read involved soft bricks, bootloops, etc.
Hopefully not having USB Debugging and OEM unlock ticked doesn't brick your phone, I'm doubtful that it will. For the poster above me, make sure your phone is all the way off, the download mode button combo is vol. down+power+home all at the same time, and hold them. A screen should pop up saying press vol. up to continue. If you're still having problems, I regret to say that I am also relatively new to this and I am not all that knowledgeable.
I just made a post about my unrooting process, hopefully it helps!

Samsung Galaxy Note 4 System software not authorized by ATT has been found

Got a huge problem with a AT&T phone Samsung Galaxy Note 4. Got it from an ebay handler. It was supposed to be rooted. However, after installing Magisk software (https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445) I got the message "System software not authorized by ATT has been found on your phone". Whenever I turn it on, I see it and the phone doesn't start. Since more than 6 months have passed, the ebay handler declined to help. I called AT&T, but since the phone is rooted, they declined to repair it even after I offered to pay. There are some solutions I found online for other samsung galaxy models, but none which works for note 4.
Tried to restore the system to the factory version, it said that restoration has been successful, but I still see the AT&T message.
I followed the instructions to unbrick the phone by reinstalling the firmware - the method that should work for all phones (not just note 3) https://www.youtube.com/watch?v=bv_NCfYemEs with the firmware for SM-N910A , however no matter how long I waited, the download process never completed.
Any suggestions?
Thanks!

Grab latest firmware for N910A from here
https://androidfilehost.com/?fid=745425885120746376
Make sure samsung usb drivers are properly installed on your pc before you begin.
STEPS
1 Download odin and Firmware and Extract it.
2 open odin tool and upload firmware in AP slot.
Odin can take up to 5 minutes to upload firmware so be patient
3 put phone into download mode
4 connect phone via usb cable and hit start.
5 After FLASH once odin shows pass boot into stock recovery by pressing 3 button combo volume up+ home+ power.
6 in recovery do wipe cache+ wipe data factory reset.
7 reboot system and wait 10 to 5 minutes.
DONE
Trex888 method should be good, however you may need to find the pit file and flash it before odin back to stock. I bought my note 4 already rooted, but the person that did it used the wrong files to flash. Mine was good but buggy. The rom flashed was not verizon, and it locked out some partitions including the one where the imei was held. I had to fix the partitions with the pit file then reflash to a different rom and i was good to go after that.
Thanks
Thanks for the reply! Great! I will try that - very hopeful

You dont need dedicated pit file unless your device has errors such as "dm verity verification failed" or failed to mount cache/efs etc etc.
If stock rom flashing by odin went smoothly no require for repartition or pit file.
Playing with pit file and repartition is extremely dangerous and can cause device to hard brick so i would not recommend unless some serious issues with device.
Fyi every samsung stock firmware has pit file in the system image by default and odin take advantage of it by it self during flashing.
Have a nice day.

in my case, whoever flashed my phone flashed an f file instead of the v file. It lost the imei and would not recognize a sim card. I tried flashing original firmware but the imei was still gone. The ONLY thing that saved mine was to find the correct pit file and flash it before firmware. It fixed my issue and got me back up and running. every original fw flash for me failed until I flashed just the pit. I cannot explain why the original fw included in the odin package would NOT work. Hence the statement of "you may need to" instead of "you will have to".
