Need help unbricking. - Samsung Galaxy S8 Questions and Answers

Yesterday I tried root my S8 (SM-G950FD) and I made the mistake of not allowing system modifications before flashing because I misinterpreted a guide. I flashed the no-verity zip and Magisk. The phone booted successfully and magisk was installed. Then I went to reboot into recovery to change some TWRP settings IE: Brightness. Then my phone said "Only officially released binaries are allowed to be flashed." That left me unable to boot my phone and also made it unable to boot into recovery. The only thing I can boot my phone into is download mode. I've tried flashing some stock roms that are 7.0 to remove the prenormal lock but they failed. I happened to make a TWRP backup before flashing but I can't use TWRP because of the official binary stuff. I'm wondering if I use the nand erase all option if that will let me flash the 7.0 stock roms then boot into TWRP and restore my backup or if they is way to convert the backup into something that Odin can flash. Does anybody know any confirmed methods to solve my problem?

You will need to flash the same or higher version of Android to fix official binary error. Use default settings in Odin.
You cannot.flash earlier versions of Android if your bootloader is lower than what is on your phone ( 5th number from right of firmware name ). If in doubt flash the latest version.

Then I went to reboot

Ok so in few minutes from now the rom will be finished downloading. When that is done what version of Odin should I use and what files should place in Odin. I know this may seem stupid to ask but I'm not going to let myself make anymore stupid decisions after not installing the rmm bypass.

Quick Update, the rom finished downloading. I wasn't able to flash it. It gave me the error that the Bootloader had: 4 and the binary had 3... I was able to flash cp by itself tho and that set the system status to samsung official but the binary status is still custom. That made it so my phone only booted into a "Update failed screen use smart switch" screen ( I've tried smart switch before it doesn't detect my device). I can still get it back into recovery and flash old cps to get it to turn off without bootlooping into the smart switch screen. I'm wondering if I flash csc to factory reset if that will help at all. Guys what do I do??

Excuse my language but I ****ING DID IT!!! I don't know this worked but I am going to roughly call my process. So flashing the stock rom initially failed. I flashed then CP which for some reason always works and then AP which began but failed. This set the binary text to "Samsung Official", system status was still ****ed as custom. So I restored the cp and ap(?) from the crgb oreo files posted here. Then I flashed cp that passed, then csc which passed and then tried AP. After some time... It passed. The phone rebooted. The official binary bull**** was gone from the bootscreen and the phone booted into recovery. It installed some sys update stuff up to 30$ then erased some things which took awhile. Then the phone booted into initial setup and I now have ACCESS TO MY PHONE AGAIN!!!
For anyone interested in what FW I flashed PM me.

SM-N910F > Bootloop // ROM Problems || Please Help

So.. hello.
Normally I don't come to forums to get help... but yeah. This is kinda bad.
I've got a little situation here.
I got my new Samsung Galaxy Note 4 (SM-N910F).
It was delivered with Stock 5.1.1.
First try:
I booted to the Downloader, fired up Odin, let it download the Autoroot.
Then I've got a bootloop.
Second try:
Booted into the Downloader, fired up Odin, let it install the 5.0.1 Stock ROM (Ending with 'BOB4')
It booted normally , then two things pop up constantly:
Something like "phone.xxxxxxxx.xxx Service crashed".
and "NFC crashed."
So I can't even unlock that phone.
Third try:
Booted into the Downloader, fired up Odin, let it install "N910FXXU1COI3_DevBase_alexndr".
Ended up in a Bootloop.
Then I tried to install the Bootloader aswell as the Modem and the Kernel, which are also in alexndr's Thread.
Ended up in the same Situation as the second try.
I don't no what to do anymore.
I'd really love to hear some help from you guys.

The third attempt was incorrect, that file is to be flashed from a custom recovery.
The second try might be because you did a dirty flash (Need to wipe data)
The first attempt boot-looped because in order to root in 5.1.1 you need a rootable kernel and the latest SuperSU (Not CF-Auto root)(Kernel is found in the Android Development thread)

Thanks for the response.
What can I do to get a correct working System back? (Theoretically, I got time and bandwidth.)
Since flashing the Stock ROM did not quiet work.

KNOX Flag is already 0x1. Means varranty is void, isn't it?
So I don't think they will help me.

I've already tried to flash TWRP via Odin, but I've never seen it.
Flashed recovery was for trltexx.
Getting to Recovery should be the same as getting to Download Mode, or?
Anyways. Will try it with tbltetmo and report back.
// Just installed the tbltetmo.
// Can't see how to get into the recovery.
// Am I missing something?
Update:
Just signed up at sammobile and downloaded the BOB6 (4.4 i think) for T-Mobile.
Flashed via Odin.
Seems like it does work again.
Currently its installing like 260 Apps.
Let's see.
// Edit: Nah. It got even worse.
// But I got a Recovery. So that's something.
IT ****ING WORKS NOW
Went into the recovery and cleared cache and data. (Kinda stupid I did not do it inb4)
Do a clean install in Odin. Since it came with stock android 5.1.1, then flash the 5.1.1 stock firmware in Odin. If you have a locked device of a specific carrier it will be even better to use the firmware made for that carrier only. And check the "Nand erase all" option in odin before hitting the start button to flash. That will erase all the data from ur phone and will do a clean install. Your phone must then boot normally. Also note that android 5.0 root file may not work for 5.1. Also check the model number before flashing.

dm-verity verification failed

2 days ago i flashed twrp on my pure stock note 4, i did backup my rom including EFS using twrp and then flash kyubi rom with nameless kernel, it all went well. just now i wipe data ,system, cache on twrp and restore my backup stock rom and it went well too...and then i try to flash stock rom using odin so i can get back the stock recovery mode for OTA update when MM releases.. the flashing was a sucess and phone booted but my data inside werent wipe.
so i went to recovery mode and saw this dm-verity verification failed on the bottom i proceed to wipe data and reboot my phone, its all working now no problems except i cant reset my phone with the setting inside it will just bring me to recovey mode and stay there with that message.
now i did some research, some saying will bootloop and stuffs but mine is all ok no problem except i cant reset it inside the settings..
anyone can help me get rid of that message/problem?
If you format everything in advance format in twrp and then flash stock firmware this message will go away.
got the same problem. Then I went to a local store. They helped me. Here are steps
1. Pull out your battery, check your serial number (S/N:....)
2. Download smart switch, enter emergency software recovery..... Enter your serial number
3. Turn off your phone. Enter download mode or sth ( I don't remember it clearly. just power + vol down or up. just try it)
4. Smart switch will recognize your phone. Choose a firmware to download. then wait
5. Enjoy stock firmware
Use kies3 reinstall drivers, then use emergency recovery in kies to reinstall your current firmware or opt to update to latest or most recent release or version then follow kies instructions

Hello everyone
I have found a way to fix dm-verity and DRK issues and it works like official, meaning no errors in stock recovery and OTA works with Official firmware, the problem is related to corrupted/deleted 3 files on /efs partition. I have tested it on SM-N910C so I guess it works on other Exynos variants, perhaps even on snapdragon if the partition layout is similar? Kies won't restore DRK or dm-verity check because it doesn't write to EFS. I can fix yours if someone is interested via Team Viewer, you will need the following:
1. PM contact me for Skype ID
2. Stock rom, rooted (any root method)
3. Adb debugging enabled and drivers installed (Kies or SmartSwitch)
After repair you can enter your stock recovery and confirm there is no DRK/dm-verity red letters error.

Mine still says fail. but it also says "need to check drk first" could anyone possibly help me im stuck.the phone loads up and everything. but when i try to root or anything or flash any other firmware than n910pvpu5dqi5 it fails about 4 seconds in to flashing on odin. ive downloaded every possible firmware specific to the SM-N910P but only one worked.
im a big noob with the note 4 this is my first luckily its not my daily phone yet. im very familiar with the note 3 n900t but im finding they are very different. any advice would be appreciated!

If you just unlocked your bootloader and thats it, your rom should still be the stock one.

SM-T580 Unable to flash MM version OS after 7.0 OTA update

Hi there,
My tablet got updated to 7.0 Nougat here the other day. Now a few functions I needed in 6.0.1 is no longer working in Nougat.
So I of course I downloaded stock rom, odin, and added the files to their corresponding selections, and as I hit Start, it reads the file, and as it goes on to flash system or data, it just fails right out of the blue. This is early start even before its flashed anything it seems.
The error code showing on the tablet is: "system rev. check fail device:1 Binary:0"
FRP lock is OFF aswell. Tried flashing it over a custom ROM aswell, but same error persists. It actually started asking for PIT file all of sudden. But even with that handled, it still gave fail on same place. Tried 3 different OS versions of 6.0.1 for my tablet.
Any idea how to bypass this version check? It's like the tablet has added some data into its motherboard saying its on 7.0 and nothing below is allowed except custom. Is there any way to flash the downloaded stock ROM to be flashed in Odin, in TWRP?
Also just using a custom ROM isnt an option due to safetynet is a part of some of the functions I require.
EDIT:
Just after typing this, I managed to use V5 of Ultra Lean ROM for T580, did full unroot of SuperSU after a full boot, and said yes to attempt Stock Boot Image, and No on Stock Recovery. Now safetynet gave validated status

Tried rooting my S5e following topjohnwu's instructions - security check fail: modem

So I tried rooting my S5e following the "system-as-root" part of the original magisk installation instructions (https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root), but odin stops short from being finished with "FAILED", and my tablet tells me: "SECURITY CHECK FAILED : modem"
How do I recover from this? Flash an unmodified firmware using odin?
Cheers

solved!
flashed the latest firmware which I downloaded with frija, then went through the process again but before flashing magisk_patched.tar I removed all the extra files from it as described in https://forum.xda-developers.com/tab-s5e/how-to/galaxy-tab-s5e-sm-t720-root-t3947806, now it works and is rooted.
NO MORE ADS!
BACKUPS!!
FIREWALL!!!
YAY is me.

I also tried rooting following the step but am having this same problem, I tried flashing the new firmware from Frija but no luck still get stuck on the 'security checked failed : modem'
I also tried just flashing the tar file but when I boot back into the device it's not showing as rooted. am I doing everything right?
I'm a bit of a noob so any help would be great

1 you have to get the right CSC for your device e.g. XFA
Once I also downloaded a strange ROM. It had file dates (inside the zip) months older than the patches or update level it was supposed to have. In this case I waited several days and got a ROM with dates that made sense and flashed without the error.
2 ??? flash did not go well -> seems to me you are technically on stock which means no root
If you succeed to flash the Magisk patched AP file then you have to reboot to recovery to actually activate Magisk root.

[sm j730f] Bootloader fail and TWRP boots into black screen

Greetings everyone,
I decided to post my problem with my phone after searching the entire internet for similar problem but with no luck. Anyway I used to play around with my Samsung j7 pro for 2 years, I managed to flash twrp and thus many other custom roms, until last week when I recklessly flashed a sboot.img.tar file through Odin in order to fix cellular network in a rom I flashed earlier, this alone bricked my phone refusing to get past the Samsung logo, so like I do always, I tried to restore my phone by flashing the stock firmware (9.0) which I always keep on my PC, but surprise, the phone refuses to go through the process and gives me this error:
sw rev check fail bootloader device -1 binary 6
(same with 8.0 and 7.0 firmware)
I searched the internet for same error but with no luck, because I understand it's a mismatch between device bootloader current version and the firmware bootloader's, that they should be the same or higher, meaning you can't downgrade, I get that! but I never seen device with negative figure (-1) what that's supposed to mean? my device bootloader used to be on 6, how did it managed to jump to minus one ?
then I tried to flash TWRP to see if I could flash a rom and get around it, so I did, but when booting into recovery the screen goes black, I thought first the phone turned off, but not really, because TWRP seems to work with screen completely black, I knew that because I accidentally touch the screen and I sense vibration, I managed to reboot the phone via twrp just by guessing the buttons location (screen always black) in order to prove that TWRP is working with screen off. I tried to flash multiple TWRP versions but the same problem, no screen just touch, by the way there is nothing wrong with display hardware because it shows Samsung logo at start and also can boot into download mode just fine.
I hope someone could help me overcome this big of an issue, because I tried everything.

First, can you try installing any custom rom, blindly(since you said the screen is black when you boot in recovery).
Second, can you try flashing stock firmware without the BL part in Odin?

I tried blindly many times flashing any custom rom but with no luck since it's really hard predicting the buttons location on the screen, I probably need another phone replica with working twrp to mimick the exact moves.
For stock firmware, I manage to install it without BL but when booting it's just stuck on the Samsung logo, and when booting into stock recovery nothing just black screen, and booting into download mode it seems that the installation didn't change the binary -1, since I could see it on the screen

This is a screenshot when I try to install stock firmware (with BL)

Can you try flash other sboot files from the link you gave me? Try to flash some sboot file, and then make full flash of your stock firmware.
If not, maybe you can try flashing sboot with heimdal https://www.glassechidna.com.au/heimdall/
I have the same issue, any help or advice?
Flash Ășltimo bootloader e modem CP
Flash Any Custom ROM
Did you flash misc partition ?
If your device keep booting in blackscreen, you need to erase misc partition.
Here, is the guide for erasing MISC partition: https://forum.xda-developers.com/t/...omi-redmi-note-9-xiaomi-redmi-10x-4g.4209299/
The guide is for REDMI NOTE 9, so if you try to perform the method 1, you can cause more damages to your device.
Please, follow METHOD 2 only !
If TWRP is not working perfectly, obviously you need to flash stock rom recovery.img.
Good luck
