[HELP] Samsung S8 problems (Root, OEM, Firmwares, TRWP, Odin3) - Samsung Galaxy S8 Questions and Answers

Before I rooted my G-950FD samsung s8 phone, everything is normal. However, I accidentally restarted my phone with OEM off and stucked at the bootloop with blue screen says downloading. I tried various tutorials on how to use Odin3 and flashed the AP file to my device but apparently it doesn't work. The same message says "Only official released binaries are allowed to be flashed'". I'm stuck at the downloading blue screen page and unable to restore to the original samsung firmware.
Moreover, I went to the samsung help center to help me out but they said mine already void warranty so can't.. Only option they gave me is to buy new motherboard for the s8..
After that, i went to the third party phone repair shops.. they actually managed to bypass it and safely restored to the original firmwares. ffs samsung repair costs more than I actually send my phone to the 3rd party repair shops. I would like to do the restore on my own but what did I missed? I really want my phone to be rooted. But, the last time I rooted, and try to restart it. It will automatically soft brick my phone.
All solutions is much appreciated guys

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,

Did I make jewellery out of my s7 edge? :S

I have the S7 Edge SM-G935F, which is the exynos version I believe.
It starting with unrooting, which boot looped my device. I have tried samsung kies firmware recovery but the download always stopped at a certain percentage saying an error was found in the dowloaded file. I tried to fix it by flashing what I believed was the stock bootloader with odin but that made my problem worse.
It turns on and shows a red coloured screen, and the voice assistant kicks in to babble but seems to not respond to touch at all. I think I can go into download mode, because I've seen a shop assistant get into it when I took it to see if they can fix it. Unfortunately It would cost 230 euros, which I cannot afford. And in case you are wondering, no I didn't buy the phone. I got it as a birthday gift, as I never owned a smartphone before that.
I loved trying out apps and tweaking the phone with root, but unfortunately I wasn't careful enough.
Is there any hope for me? Thanks in advance if anyone could help me out.
EDIT: Thank you to both replies! I did as you said and I downloaded the correct firmware. It seems the one I flashed before was actually incompatible. Everything works now thought, I lost all data but better than having no phone.

Go to sammobile.com, create an account & download the latest firmware for SM-G935F. Install Samsung Drivers on pc. Boot device into download mode. Extract the downloaded firmware and use odin to flash it.
In case you don't know there are 2 S7 phones, S7(930F) and S7 Edge(935F) and their firmware files are not exactly interchangeable.
I think you might flash s7 firmware on your s7e since red screen is the same symptoms when you flash S7flat kernel on S7 Edge. The fix is easy, just reflash again with the correct file.

New S7 Design Flaw - Causes bootloop/brick

Hi, after going through the process of getting the S7 fixed - and Samsung denying everything (as usual), I'd share this issue as it's been happening to multiple Samsung devices in the workplace.
Here's how to brick your phone:
-An unwilling user goes on a business network, which happens to issue Android security updates via "Android at work".
-Due to Samsung making changes to Android, it manages to break the OS.
-Enjoy a chance to either go into infinite bootloops or if you're lucky - it'll boot in an unresponsive state with a line near the top and an empty desktop.
Now get this, because we tried to flash official firmwares provided by sammobile, the software state has been changed to custom. While the "warranty void" flag remains 0, they claim the device was rooted and want to charge ~$900 for it to be fixed.
As an owner of a S4 a few years ago, who's battery exploded. (And gave me a document to sign to not tell anyone about this) A note 5 owner who's display died while overseas and Samsung refusing to repair, as it wasn't bought in the US. I do not trust Samsung to make a reliable device.
Maybe your work security updates need updating / fixing
And flashing stock with ODIN does not change status to custom, as it is a stock ROM - in fact if your status is already custom and you use ODIN to flash stock, it will change back to Official
have you tried to reflash with odin?

I also got a custom status once flashing samsung firmware, but that was only because the flash was terminated before completion.
Knox flag was still not triggered.
Flashed again with the same stock and now all was fine.
Showed back as Official.
I think you should try to use SmartSwitch if you want to go back to the original firmware, tho it comes with a cost of resetting the whole device including internal storage, you could boot into safe mode, copy your data, then open SmartSwitch > More > Emergency Initialization (or something like that) > 2nd Tab > you put the device model then Search > you put the S/N (check the back of the phone for S7, or under the battery for some phones) > follow the exact instructions > it will be initialized with the latest software and good as new. Hope this helps, also everybody knows Samsung likes not to be responsible on something they did, that's why xda and the devs here exist!

Stuck in bootloop on untouched stock rom, unrooted device.

This afternoon my S7 Edge entered a boot loop. All I was doing was reading the news, in the same app I have been for the past couple of months. The device is untouched in terms of modifications since purchase, so unrooted stock rom. I can get into download mode, and occasionally, recovery mode. I wiped the cache as my first attempted fix - no change. Then did a factory reset - no change. I then thought I'd try loading twrp so I could flash a custom rom, but Odin was unable to flash it due to FRP Lock blocking it. I then downloaded the latest stock rom from sammobile, and was able to flash this via Odin. On first boot the device did start to load, and reached 10/19 in optimising the apps, before starting the boot loop again. I am kinda out of ideas now. Any help would be greatly appreciated.

Go into settings>developer's options and ENABLE OEM UNLOCK then
go into settings>general management>reset>factory data reset and
reset the phone.
Once you have done that the phone will work properly without rebooting
provided that you have successfully odin flashed the official samsung
G935F S7 Edge firmware prior to doing a factory data reset.
Good luck, have a great day!
Thanks for replying. Unfortunately I can't get into the phone at all. Only screen I have access to a recovery and downloader.
So I left the phone alone for a while and tried booting into safemode. This time it worked - sort of. It is asking me for a password, but I have never set one. I only ever set a pin and fingerprints. But since wiping everything that doesn't seem to apply anymore. What is the default password? I am referring to the phone password, rather than a google account obviously. I am not at that stage of the boot up.
Update: found the password (default_password), still boot looping on the optimising apps screen.
If you still can't get into the phone like the person above said, I would use Oden to reparation and reflash your stock rom. If it still gives you issues, I'd suspect hardware fault.

I have flashed stock rom (initially the version that matches my carrier, although my phone was bought sim free and unlocked, and then the version for unlocked phones (BTU in sammobile I think)) but it still just boot loops. The phone can remain in download mode as long as it wants, and previously, when it was asking for the password, it was able to remain on that screen indefinitely. I would have thought if it was a hardware problem the boot looping would happen regardless of the action on screen. Immediately after flashing the stock rom, it did start to load before ooting. Now it just boots immediately at the Samsung Logo.

Just to be clear, do you mean repartition here? I have not checked that option before, will try it.
Even without the PIT file. Flashing stock rom should have fixed you... which carrier do you have? If Verizon, they have a recovery assistant software that works in these situations. Or if not try "samsung kies". If all else fails I'd give Sammy a call.

I am in the UK, and my carrier is Three, although the phone was purchased sim free. I tried samsung kies (phone not compatible apparently), samsung switch (phone does not support initialization). I may have to call Samsung, but I purchased the phone on eBay, so no warranty (never doing that again!), so I guess it'll be expensive to get them to sort it. I've taken it to a phone repair shop this afternoon and the guy reckoned he could fix it based on what I said. We shall see. I don't have to pay unless he fixes it, so worth a shot.
You can wipe your phone by entering recovery. Default recovery has the wipe option.

Hi
Just curious...why do u say u don't have warranty just because u brought from eBay?
Surely it doesn't matter where u brought it and it still has warranty.
Have u tried contacting Samsung?

Pretty much all warranties (including Samsung - I checked) are contracts with the original purchaser only. Even if you have proof of purchase, you then need to match the records they have of the identity of the original purchaser. Whilst some manufacturers will be more lenient, others will follow the official policy strictly. Speaking from experience here.

For those perhaps in similar situation in the future, Samsung didn't care that it was purchased second hand, despite what the fine print says. They just looked at the serial number. In the course of trying my own repairs I flashed a custom rom, which of course tripped the knox warranty void bit. When I took it into the service centre they saw this and then wanted to charge £225 for an out of warranty repair. I refused at the time. I later called Samsung support and explained the situation (I said a phone repair shop must have done the flashing). Again on the phone I was told it would be an out of warranty repair, and this time I agreed. They collected my phone and returned it to me today however, with no invoice or mention of charges, so it looks like they just did the repair no questions asked.
I have the same issues, so far I'm getting by with flashing a stock rom with pit file and doing repartition and nand erase, normal cache/ factory reset doesn't help, it sometimes even boot loops while in twrp.
Somehow Odin flashing helps for a random amount of time, but it has thus far, crashed after a month, or a couple weeks since the last flash, etc. So far it's been my 5th boot loop event in the last 6 months
It sucks but as I got mine from another country (/win), didn't get the warranty ;( plus I tripped Knox by rooting.
sounds hardware related to me..
i had a friend with a note 4 who had similar problems it would hardly ever boot sometimes boot straight into download mode..
if by chance it did boot it would boot once the device was locked for a short time it would reboot and start over again bootlooping..
it was the emmc flash memory that was failing...
a workaround i found for this was the first thing i did when finally getting it to boot was install "Wake Lock - CPU Awake" and set it to never let the device sleep and to startup on boot...
this "fixed" it as long as your phone does not turn off... he had insurance though and sent it off and they sent him a new refirb
again this note 4 was untouched never rooted or anything

im having pretty much the exact same problem except ive been unsuccesful at flashing the stock firmware for my galaxy s7 active (SM-G891A). the active series isnt the most saute after, so finding the right firmware is alil more difficult. which im pretty sure is how i got into this situation! my question is what exacly does checking the "reparation" option do. i read to leave to leave it unchecked/unticked. maybe thats why ive been unsuccessful. and someone told me awhile ago not to fill in the "bt" box becuz i have a locked bootloader. this correct or no?

Samsung S8 Security Error During Boot

Last week I woke to my phone showing an error "System software not authorized by AT&T has been found on your phone. Please turn off your phone and go to the nearest AT&T store for help." This phone was working great when I went to sleep a few hours prior, and has not been rooted or modified in any way.
As you can probably guess, the AT&T store was not able to help, but referred me to their phone based support. When I called, the phone rep stepped me through the boot loader menu (vol up, bixby, power) and we reset the cache, then the full factory reset. Nothing made any difference.
So, I figured I would try re-flashing with official Samsung Firmware. I used Odin to flash the G8 FW that matched my AT&T model. Great news! My original error is fixed. Unfortunately it has been replaced with one just like it: "Security Error: This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair / return for this issue may have additional cost."
I also tried a slightly different version of firmware but get the same result. A third version would not flash due to a "SW_REV_CHECK_FAIL: [abl]Fused 5 > Binary 3" error, which I assume is because the firmware being flashed is too old.
Any suggestions on how to unbrick this phone?
Thanks,
Sharkus
