Bro i have also same problem when I was flashing twrp through Odin .
My phone is stucking on twrp twrp is blinking again and again.also when I try to go to the download mode it automatically comes to bootloader and then to twrp please bro help if have fixed it

I was just speaking to a phone retailer and he told me how Shamshung M-series phones are getting locked by OEM manufaturer automatically within 6-7 months of usage (he was ready to show me evidence also so I believed him) , he said there is no solution to this So pls guys just an advice DO NOT CONNECT YOUR PHONE TO INTERNET FOR ANY OEM UPDATES,
1> TRY TO BUY PHONE FROM ONLINE STORE (BECAUSE RETAILER WILL FORCEFULLY UPDATE THE PHONE EVEN IF YOU TELL THEM NOT TO UPDATE)
2> FIRST, DONT PUT IN ANY SIM CARD IN SIM TRAY
3> SECOND, DISABLE WiFi (DONT SAVE ANY WiFi PASSWORDS) & TURN ON AIRPLANE MODE
4> THIRD, TURN ON DEVELOPER OPTIONS- USB DEBUGGING "ON" & DISABLE "KEEP MOBILE DATA ALWAYS ON" UNDER DEVLOPER OPTIONS
5> FOURTH, USE "DEBLOAT LIST" ATTACHED BELOW TO UNINSTALL INSTALLED APPS USING ADB
6> FIFTH, ONLY CONNECT TO WiFi FOR FEW SECONDS SO THAT THE OEM UNLOCK OPTION IN DEVELOPER OPTIONS GETS GREYED OUT.
7> SIXTH, FLASH ODIN-TWRP TAR FILE, WIPE/FORMAT DATA, BOOTLOGO PATCHER ZIP, MAGISK 24.3 ZIP, PRISH KERNEL (OR ANY KERNEL OF CHOICE), THEN FLASH TOTSUKA/PIXIE/CLEAN_OS/CrDroid10 (ONLY 3 STOCK-BASED ONEUI ANDRO 11 ROMS AVAILABLE, NO CUSTOM-BUILT NON-ONEUI ANDRO 11 ROMS AVAILABLE NOT EVEN M30S PORT ROM), VBMETA IMG
8> REBOOT TO TWRP, WIPE DATA
9> AFTER DEVICE BOOTS FIRST THING IS DISABLE WiFi & TURN ON AIRPLANE MODE, INSTALL NETGUARD FIREWALL APK THROUGH PACKAGE INStALLER (ALWAYS KEEP NETGUARD ON THROUGHOUT THE PHONE LIFETIME OTHERWISE SHAMSHUNG OTA MIGHT KILL THE DEVICE),
10> DEBLOAT BUILT-IN GAPPS USING ADB
11> INSTALL MICRO-G FROM TWRP
#NOTE: FOR FACTORY RESET SCENARIO REPEAT STEPS 10 & MAYBE 11 TOO.
AVOID VISITING OR USING OEM WEBSITES AND APPS. REMEMBER, FOR GUGLE EVERYONE IN THE WORLD IS A POTENTIAL TERRORIST.

Zte nubia z9 mini (urgent help required) bootloop

Hi ,
I am new on this forum so sorry moderators if i have posted this where i shouldn't have . I recently got a ZTE NUBIA Z9 Mini and i wanted to root it so tried different methords and somehow i managed to soft brick it or as they say its in a bootloop. Whenever i try to boot the phone with volume up button + power button just the home screen nubia logo appears and it stays there. I am absolutely clueless what to do ... followed some youtube videos to flash new rom using fastboot but apparently it needs back up files which i don't have .
Someone please help me
Thanks !
Possible Fix?
Hey have you tried to boot to recovery? it can depend where you brought it from. I got mine directly from the nubia store on thier website and it came rooted with a recovery system already in place, i had the same issue as you I booted into recovery power+vol down downloaded the rom again or most up to date rom from the website or in my case needroms website . Then i just installed the rom from update on the sd card View attachment 3357925 then it took about 3-5 mins to install and i rebooted it. View attachment 3357928 After this it should be as normal like flashing any rom onto any android device then wolla done even all my apps and data remained safe because it was only a software update flashed over.

I have the same problem.
If I press volume - and power device doesnt go to recovery, it just show Nubia logo on the screen for a while, then screen is black, That is all. If I plugg it into PC, computer can see one part of partiition with -Image- directory and a few unreadable partitions..
Do you know what to do, please????

Don't do nothing I had the same bug here with the logo Nubia again and again.
Just let the phone discharging itself (as you can't remove the battery).It will take around 24 hours.
Put an official rom on your sd card.
When the battery is out (try to power and if nothing happens it's good) just plug your phone to charge (not on pc) and try to go to the recovery.It should works.
Then load the official rom and after you will restore your backup (if you have one).

I tried this already, just without sd card. Problem is, that I cannot go to recovery. If I press volume - and power I'll get just on logo screen, nothing else...
If I plug completely discharged phone on charger and press nothing, then just charging procentage appear for a while and then is dead again.
you can use one-click-tool.
first you switch off your.....try two or three times....or try again and again ....if you switch off your fone....then try to switch on in to fastboot....i have downloaded a fast boot rom..........1.16 version........extract the downloaded folder then first you click on ....z9 mini app in this folder.....and connect your mobile to pc......its start in automaticly.......wait for restart.......ohla....your mobile runs....https://drive.google.com/file/d/0B14zmeE7OLybaW5KWS1rME1Fd0U/view?usp=sharing
Problem solved!!!
This helped:
- Use a fast microSD card and copy on the root folder the original Nubia ROM (you can download it on the first page of this thread)
- Insert this microSD card into the phone
- Turn on your phone and let the battery completely discharge
- When the phone is turned off, press and hold Volume - than connect your AC adapter (USB cable connected to PC does not work), en Should start in bootloader menu
- If you can successfully start the bootloader menu, run the phone into recovery mode and than install the rom from external sd card
At the moment there is not any tool or bin format image for this phone

Hi @ all.
I have managed this problem using volume up and power button. After first bootscreen hold the on button and wait until the second boot screen turn of. Release all keys!

Thanks a million, it saved my phone
Hello everyone!
I had the bootloop problem and I could solve it following your recommendations. My problem is that the original ROM installation process was suddenly stopped (I don't know exactly why) and now I have no access to the OS. Everytime I reboot it, the system goes to the bootloader showing this message:
Bootloader Menu
You entered this screen because:
No kernel (boot partition is bad)
Now you are in fastboot mode
The phone is fused
Then I have access to TWRP or to the original Nubia recovery, but I can't install a new ROM. I can restore backups but when I restart the system it goes to the bootloader menu again. Any solution for this issue?
Thank you in advance!

Hi again!
I finally could flash the official ROM via TWRP. Initially I was trying to flash this ROM from the SD card, but the installation didn't work neither with TWRP nor with Nubia recovery. Then I copied the ROM to the internal storage and flashed it with TWRP with no more issues. Hope this information is useful for other members.
Thank you!

Hi once again, dudes!
As I told you this morning, I finally managed to fix my problem with the no-kernel message. However, after the reboot, I have lost wifi and bluetooth connections. When I turn on the wifi it doesn't even search for available networks. I have tried with official ROMs 1.16 and 1.19 and with a custom multilanguage ROM, doing factory reset (sometimes even system formats) before each ROM installation. Everything is working properly but I can't turn on the wifi and bluetooth.
Any idea or solution? Thank you very much!
Solution to WiFi and Bluetooth problems
Just to let you know that I finally managed to solve my problem with WiFi and Bluetooth. I got a backup of the 'persist' partition from a colleague's Z9 mini that worked perfectly and restored it in my device via TWRP.
RAW format image caputure
hi guys,
Since Nubia Z9 Mini runs on Android 5.0 (Lollipop version) with latest Camera 2 APIs with Manual control over camera, would like to know if the default Camera App supports Image capturing in RAW format.
Also can we use third party application like Camera FV-5 which supports RAW format image capturing feature in Nubia Z9 Mini,
Since you guys are users of Nubia Z9 Mini, pls. confirm this for me..
Thanks in advance..

And how do you let the phone discharging itsel if the initial screen with nubia logo dissappears after a few seconds???
It won't discharge itself because it switchs off every time.
Anyone can tell me what to do?

Problem with Nubia Z9 mini
I've had this phone for 1 month and installed this ROM - http://forum.xda-developers.com/general/rooting-roms/rom-nubia-z9-mini-nx511j-rom-twrp-t3142204
Phone was working perfectly fine this morning but I noticed it had only about 30% battery left so I tried to charge it and it wouldn't charge? Tried computer cable, original Nubia cable and even others and nothing charged the phone. So decided to restart the phone to see if this fixed it and now the phone is just stuck on Nubia home screen . Can't restart or turn off or anything.... If i press volume down and power button it makes the screen print/camera sound and that's all i can do.
I'm not the most technical with all the mobile software stuff ect but can manage if guided
Also the phone is becoming really hot
Would greatly appreciate some help with this
thanks
I have a different problem here . I had stock ROM (India) when I purchased. Very laggy. I rooted, loaded TWRP, put MIUI-6, it was better, all working, but a little laggy too. Later put [email protected] The ROM is good (faster, very clean and clear voice, faster wifi etc...) but later found data not working. I read somewhere that the ROM may not be suitable for Indian version. When I want to load back the backup of MIUI-6, I am unable to boot in recovery mode. Only Nubia logo appears with all combination of switches. I am able to enter into recovery menu (Vol- and power). When I select "boot into recovery mode", only Nubia logo appears. I saw the directories in the PC, there is no TWRP directory in the internal storage. I tried to once again load TWRP, in the PC I get everything o.k, but in the phone, it strucks at recovery screen, and hangs. I have to press vol- and power to reboot again. It reboots o.k. Now, how do I get into TWRP recovery? Is there anyway to make data working with the present ROM? I tried all, like, draining the battery ...... etc.... not helping. Some information in this regard will be of great help.
I have tried everything possible as below.
As the above case, I am also using Indian version of Z9 Mini. I have flashed TWRP and then flashed MIUI6 & 7 and after that I came back to original rom through backup. Then after that, once again I came to MIUI7, after that when I tried to came to original rom, I can't. So I have downloaded last ROM from [email protected] , that is 3.61 . I that, my sim cards were not detecting. After that, when I tried to open TWRP , I can't. Just Nubia logo screen. After that I tried One Click Root Tool to flash TWRP. At that time , when my phone gone for rebooting , it's gone. Now whenever I tried to boot the phone or boot into bootloader , only that nubia logo screen appears. When I tried to flash through fastboot , device is not detecting. Why so ? . No partitions are seen on computer . I have tried all above steps , but no help . When I tried that fastboot flashable ROM by vijay2 , phone reboots to bootloader and in computer, it flashes everything. But after reboot , it is as same as before . What to do ? . If it is the case of missing driver , then please give me a link for it.

SM-N920W8 stuck on bootloop after flashing stock rom AND wiping data/factoryreset

Hi all, I am really at my wits end.
I have never unlocked, or rooted this phone. I was having random reboots/bootloops constantly on my phone so I decided to reset cache as per many people's instructions.
It seems that evena fter flashing stock roms and wiping the data/cache it remains in bootloop. After flashing with odin, it will say installing updates, go to 32% then will say "erasing", then say installing updates then bootloop.
Does anyone know how to fix this? I believe my DRK is okay, no errors there.
Should I try to root, unlock and install a custom rom? What are these kernels and should I try those too?
Please, if anyone has anything they think might work please, please please help me.
Thanks,
Tom

Sprint Note 5 Boot-looping trouble!?

This is my first post and I'm in need of some help that I can't seem to find anywhere when searching the internet. I'm not a developer nor am I close lol I just have tons of fun learning the development process - it's seriously one of my favorite things to do. Anyways I've messed up royally with my Galaxy Note 5 N910P and I'm stumped on what I should do next! So here's the issue: My Note 5 will not stop boot looping!!! I've flashed stock, almost every version that I'm able to and nothing has worked. The last thing I remember doing before it started this b.s is rooting with CF Auto root. I've always used twrp then flashed Supersu and the dm verity and never had issue! But after flashing the CF Auto root I kept getting kernel is not seandroid enforcing and then the dreadful boot loop issue that has been going on for three days now! Is there something i'm missing? or not doing right? Please message me and let me know, and if this is the wrong place to post about this, I dont mind if my post is taken down just at least help with my question some how! Thank you, XDA is my favorite place - you guys are awesome, I don't trust any other source!!!

First of all you have entered wrong model no here note 5 model no should be SM-N920xx
1)Have you enabled Oem unlocking from developers option before flashing twrp and cf-autoroot using odin? If not then you done a mistake!!
2) Have you tried to flash latest stock firmware using odin with latest usb drivers installed on you pc and proper odin flashing guide?(Flash latest 6.0.1 for your device with latest usb drivers installed on pc and connect phone to main usb port using original usb cable) After flashing stock rom if your facing bootloop then you can try reset through stock recovery (Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
3)If you can boot into twrp recovery normally then flash any custom rom suitable for your device i.e. for sm-n920p..Custom roms are pre-rooted so no need to flash cf-autoroot..Flash custom rom, if you successfully boot up the rom( It's difficult to boot custom rom though if you haven't enabled oem unlocking you will face custom binary is blocked by frp protection),then enable oem unlocking from developers option and try flashing stock rom again
4) Next option for you is download Samsung smart switch for pc, install latest usb drivers on your pc, connect your phone to pc in download mode(Press volume down+power+home button simultaneously),in smartswitch select emergency software recovery, it will ask you imei,model no and serial no which you can find either on box or back panel of your phone,smartswitch will detect latest stock firmware for your device, hit update now,give some time until update complete..Your device will be automatically reboot..If even you face bootlopp, then goto stock recovery(Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
**IF SUGGESTION IN SECOND POST HELPS YOU THEN ITS DONE, AVOID NEXT SUGGESTIONS**
Are you sure you can't install cf auto root again to solve it? IF not...
I did a search and got hits for twrp for N910P. Get it loaded, get it wiped and have another shot at success. Next way to get rid of the persistent rooter gone rogue, load up a factory BL + AP. If that doesn't work download another version and try again.
I've enabled OEM unlocking, flashed latest stock AP...BL.. And so on, factory reset in both factory and TWRP. I have also tried flashing CF Auto root again to see if that would fix it also custom ROMs bootloop except for CM13 and Lineage OS- Which is weird because the ROMs are for the SM N920C model and I'm and Sprint model, So I don't understand that. Weird!! Everything recognizes me as SM N920C except when I am in download mode. Also, having no imei or any back ups make its even harder since my computer completely crashed on me because I am unable to use Samsung smart switch due to the wrong model and null imei. So I'm completely stumped with this issue. Not sure if its a corrupted partition or folders not being in the correct folder locations along with wrong permissions, I've literally stressed everything to my knowledge about this and I'm all out of what issues this could be related to

How to recover from Verification Failed, Bootloops, and Android/Carrier logo freeze.

In this tutorial I will inform you on three different soft bricks, and how to fix them.
You must be able to boot into TWRP and/or Odin/Download mode!​
1.) Verification Failed.
Method #1
This method will work with people whom can't reset their device, due to an unmountable /data partition, and those whom experience this error, who can reset but have valuable items, applications, videos, or photos that they don't want to lose. Must be able to boot into Odin/Download mode. (Volume Down+Home+Power)
The solution is actually pretty simple. Boot into Odin/Download mode. This has to be done correctly, not from TWRP recovery. When the prompt for "Volume Up = Continue" and "Volume Down = Cancel (Restart)" press volume down. You should no longer see verification failed, but instead be sitting on the T-Mobile logo. This is normal, and could take 30 seconds to 10 minutes, depending on the amount of data.
This method works all because of Knox. Knox is what Samsung uses to void your warranty. Companies are not allowed to void a warranty when rooting, installing roms, or recovery, unless they have direct evidence. Knox will trigger this when it isn't sure. It will try forcing you to bring it to Samsung, and they can directly find out why it was caused. This happens when it thinks that you cancelled.
Method #2
This one will require you to lose all your data, but is mainly intended for those whom cannot reset their device. Download the stock firmware from the links below. Open Odin (Jodin3 will not work! It is not fully functioning, do not try it.) and boot device into Download/Odin mode. On your computer, you should see 'Added' in the logs. If this does not show up download the Samsung USB Drivers. Select AP and then select the stock firmware. Now flash it. This can also be done through TWRP
For bootloop and frozen Android/Carrier logo just do Method 2. You usually will keep all your data.
FOR 'VERIFICATION FAILED' YOU CANNOT RESTORE FROM A BACKUP!
FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!​

Samsung USB Drivers
7.1.1 Stock Firmware
Odin3 v3.12.10
Post any bricks below that you have encountered!
I'm interested in how many variations there are, and how common they are.

Please describe this issue in further detail. Has this been happening out of nowhere, or did you just try flashing something via Odin/Download mode or TWRP.
Also, before flashing did you enable OEM unlock
This also happens when something flashed via Odin/Download mode is incompatible.
Are you still able to boot into the default system partition? If not safe mode?

I should have updated my post, I'm not sure what happened but I flashed stock through Odin and the problem went away, after that I was able to flash twrp and root/install other roms.
It's still weird that the problem happened out of nowhere, not sure what triggered it.
It goes away when u log in to google with the last account that is associated with the phone

Probs OTA. It happened to me my first 3 tries. Ended up factory reseting, and installing fresh via Odin, didn't fix it.
I just turned off auto reboot on Odin, and then pulled my battery on my J7. Booted up straight to Recovery from there.

It would make sense if it was an OTA update TY
Hi, I tried to root my phone and I got this error, I don't mind restarting the phone, but isn't there a way for me to backup my data (photos mainly) first?

Sorry I didnt respond.
Looks like you didnt flash encryption breaker. Keep this on your SD Card as its a great way to recover from these errors, and you will need it when you flash ROMS.
Just boot in recovery, flash ashix no verity no encrypt, then reboot into system. You shouldnt have this error.

He's referring to the encryption breaker file ("no-verity-no-encrypt_ashyx.zip") in his first sentence. That is assuming you already had it and should be keeping it on your SD card all the time for flashing ROMs

how to remove Verification Failed or root in the TWRP file manager without losing data

Flash ashyx-no-verity-no-encrypt.zip in twrp.
Reboot
TechNash said:
In this tutorial I will inform you on three different soft bricks, and how to fix them.
You must be able to boot into TWRP and/or Odin/Download mode!​
1.) Verification Failed.
Method #1
This method will work with people whom can't reset their device, due to an unmountable /data partition, and those whom experience this error, who can reset but have valuable items, applications, videos, or photos that they don't want to lose. Must be able to boot into Odin/Download mode. (Volume Down+Home+Power)
The solution is actually pretty simple. Boot into Odin/Download mode. This has to be done correctly, not from TWRP recovery. When the prompt for "Volume Up = Continue" and "Volume Down = Cancel (Restart)" press volume down. You should no longer see verification failed, but instead be sitting on the T-Mobile logo. This is normal, and could take 30 seconds to 10 minutes, depending on the amount of data.
This method works all because of Knox. Knox is what Samsung uses to void your warranty. Companies are not allowed to void a warranty when rooting, installing roms, or recovery, unless they have direct evidence. Knox will trigger this when it isn't sure. It will try forcing you to bring it to Samsung, and they can directly find out why it was caused. This happens when it thinks that you cancelled.
Method #2
This one will require you to lose all your data, but is mainly intended for those whom cannot reset their device. Download the stock firmware from the links below. Open Odin (Jodin3 will not work! It is not fully functioning, do not try it.) and boot device into Download/Odin mode. On your computer, you should see 'Added' in the logs. If this does not show up download the Samsung USB Drivers. Select AP and then select the stock firmware. Now flash it. This can also be done through TWRP
For bootloop and frozen Android/Carrier logo just do Method 2. You usually will keep all your data.
FOR 'VERIFICATION FAILED' YOU CANNOT RESTORE FROM A BACKUP!
FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!​

Samsung USB Drivers

I have a samsung j700t ud that had the 7.1.1 update installed from tmobile or samsung and it caused the to remain in a continual reboot loop until the battery of the phone dies. Will the methods above repair the issue?
Stuff I've tried:
1. Wipe cache
2. Called samsung and tmobile
3. Used samfirm to download firmware to use with odin that was successfully done but the reboot loop still remains.

Was the update sent out to you, or did you download it from SamMobile?
If the update was sent out to you I'm afraid I cannot help, but if you flashed it from SamMobile use an older version like Marshmallow or Lolipop.
EDIT: Make sure you factory reset device and wipe cache after installing from SamMobile.

How to | Galaxy S9 (SM-G960F & F/DS) Root Android PIE

Exynos variants such as International (F), International Dual(Hybrid)-SIM (F/DS),
i am not responsible if anything goes wrong. You are still the one who tryed to flash the files. Even tough this should work as it worked for me and some friends.
Hello XDA
This is my first post (sorry if one already exists)
Today i am going to tell you how to root the Galaxy S9 International on android 9 Pie on stock touchwiz rom.
First of all download all these files;
Prince comsy odin: https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Team win recovery https://forum.xda-developers.com/ga...cross-device-development/twrp-exynos-t3763464
ElementalX Kernel https://elementalx.org/devices/samsung-galaxy-s9/
No verity encrypt: https://androidfilehost.com/?fid=962187416754474353
Magisk 18.0 https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Now for the root
First you need to unlock OEM, you can do this in developer options,
If there is no developer options you need to enable this
you can do this in: Settings>About Phone > software information > click 5 times on build number.
When you unlock OEM everything on your phone gets wiped so make a backup!!
When the wiping is complete, turn off your phone and go to download mode (Vol down + Bixby + Power)
Then connect the phone to your pc and start odin
In odin go to options, and disable f.reset and auto reboot.
Then press the AP button and select the TWRP image you downloaded.
When TWRP is flashed, force reboot your phone (Vol down+ Power) when it is powered off quickly press Vol Up + Bixby + Power to get into recovery
Swipe to allow modifications. And format /data
Then reboot into recovery.
When rebooted mount USB Storage and connect the phone to the PC
Then you can click&Drag the other files (elemental, Magisk, No verity)
When the files are on the phone, go to install and search for the files you just put on the phone.
Install in this order:
Flash No-Verity-Encrypt
Then flash the custom kernel (ElementalX)
And as last flash Magisk.
When you did this, you want to Factory reset, Wipe cache and Dalvik.
Then you can reboot the phone, and install it.
(It is possible that you stay at the boot logo for a long time (Not the galaxy s9 one but the next one) What you need to do then is let it boot for 5 minutes, then force reboot (vol down+Power) and then the phone boots fine)
Again, just to make sure check if OEM is still unlocked (sometimes this get locked again)
Please note that when you do this, you lose secure folder and other functions, also is the knox tripped (0x1)
But the Fingerprint, Irisscanner and samsung account works.
SOMETIMES IT IS NEEDED TO INSTALL THE MAGISK MANAGER MANUALLY, YOU CAN JUST DOWNLOAD THE FILE FROM THE LINK IN THIS POST
Hope this helps.
If you do have any questions, please do the following first;
Note any errors that odin or your phone gives you. I want to help you, but i do need to know what is going wrong.
(Sorry for my bad english)

So you won't need RMM-state_bypass on pie anymore?!? Seems hard to believe...
And why exactly you need to flash that custom kernel, which benefits does this bring with it?

If you dont use the custom kernel, you will get RMM error.
Iris scanner wont work, Fingerprint wont work, Samsung account wont work. When you reboot the phone you get a little "Bootloop" at the lockscreen (Screen flashes and is unusable and your pattern isn't saved)
I dont know what else breaks because i cant even get past the lockscreen with stock kernel
(Also you get better performace and battery life)
Hope this helps
work it with s9+?
Sorry for my English...
Yes, but you want to use tgpkernel then otherwise it will not work (problems described abovel
https://www.androidfilehost.com/?w=files&flid=288240
Last samsung phone i rooted was the note 3, and i remember that doing that "tripped" knox 0x1 and this basically voided the warranty. It's the same with S9? is there some non-reversible change that happens to the phone when rooting?

Yes, the knox will still trip (0x1).
In europe, when you can show that the root is not the cause of the problem, they have to fix it under warranty.
Also there are some functions you will lose (forever)
Knox,
Samsung pass,
Samsung Pay,
S-Health(you can fix this one with a build.prop tweak)
Secure folder
If you plan to use one of these (exceptpt s-health) It is better not to root your phone (there are still external app's you can use if you plan to root your phone)
Is there a way to update the stock firmware when you have root? Or do i have to do all over again?
I have this lock screen flashing bootloop issue, what is the fix? I have tried factory restores but get the same results once I set a lock/passcode and reboot. Samsung Account and Bixby also do not work as you mentioned.
You can use TGPkernel then,
Some phones have this issue, some not.
I have seen that 3 friends of mine it worked, and also on 3 not, so this is a very weird issue
What was the fix with them is to install TGPkernel
@co9
The only way i know is to install a custom kernel,
Otherwise you have to download latest stock rom, and flash this using odin.
wich changes your recovery.img and boot.img, aswell as the kernel. so you have to flash this all over again
Thanks for the answer. I already have a custom kernel. So if i always want to have the latest Samsung firmware i have to flash it through odin and do the whole root procedure again?
I tried this method but now everytime I reboot the phone my bluetooth paired device are lost. They also get deleted if I turn ON and OFF the Airplane mode. Anyone else having the same issue ?
Is anyone else experiencing an issue where the password, pin, or pattern set before setting up fingerprint scanning acts like what was entered is incorrect, not allowing you to setup fingerprint scanning?
I've tried setting up fingerprint scanning on initial setup as well as skipping and trying after the phone has been setup but had no luck. What ever I set initially will not work when I'm prompted later on when trying to setup fingerprint scanning or tying to access other secure features. The phone just prompts to try again acting like I entered in the wrong password, pin, or pattern. I've even tested by setting up a REALLY simple password with no luck.
I have confirmed in the settings that Elemental is installed.
Edit: I did find this thread https://forum.xda-developers.com/galaxy-s9/help/root-galaxy-s9-exynos-9-0-android-pie-t3884267. I tried the no-verity-opt-encrypt-6.0.zip that was suggested in some posts but had no success. I've also tried the TGPKernel but had not change in the issue. I am able to setup fingerprint scanning on fresh firmware install but after installing TWRP and everything else the above issue happens.

Don't root this phone without flashing a custom kernel or a modified stock kernel. It will drain battery and reduce the performance or even crash the system.
Look in the TWRP thread there it is explained why you shouldn't do it.

My personal experience is i have rooted using this method and have had no problems
Hi all,
I tried to flash twrp but never succed.
S9+ last firmware from samsun android 9 pie (update from smart switch)
Then option developper activated, no oem unlock menu found,
boot into download mode and there is written oem unlock desactivated so ok
with odin try to flash (ap, reboot freset unchecked)
then fails and message in red on the phone :
"only official released binaries are allowed to be flashed recovery"
History :
I was in galaxy project oreo, i wanted to upgrade with pie, but reboot cycle
so rescue with odin and original oreo firmware, then update to pie
thanks for help
regards
To get the oem unluck button visible.
After fresh install, go to time/date in settings, choose manual and set the date 1 mount prior (march will be februar)
Than go to software update, choose manual en click on dowload updates manually.
Restart your phone and the oem unlock button in developer options will be there
Cheers
thank's for answering,
Update done, reboot ok but still not oem options in developpers section
