happens to a lot of subs of that ch )
thank u 4 taking your time to read this i apreciate it!
pd: sorry maybe my english its some roosted xD (im from bolivia):good:

okay i know a few things,
Your galaxy pay app and the secure folder app will never work again, by rooting your device you blew a e-fuse that is Irreversible.
As for your storage decrease it might be because of a wrong file you flashed, check your version and see if it matches

As said above Knox is now triggered. Which means no more apps like Sam Pay, Health, secure folder etc.
There is nothing you can do from now. It is triggered when you rooted the phone and it'll stay like that for forever.
You should have searched about everything before rooting. Asked all serious and stupid questions.

[Q] Note 4 SM-N9100 HK firmware update N9100ZHU1BOF2

Just update HK firmware N9100ZHU1BOF2 to my note 4 SM-N9100 (China version) Don't feel any differences, except it's not so warm like before. And Sim selection is not slow like before.
Has anyone updated?
which Note 4 do you have?
I tried to flash it to my N9106W but it cannot complete "security check fail: aboot" is displayed on the phone (usb debugging is on, reactivation lock is off). Odin says <ID:0/009> FAIL! (Auth)
You can't flash on N9106W. It is only for Note 4 SM-N9100 and I did mention at the subject.
thinking about flashing now. did twrp and root work fine?
ive that firmware and root and twrp working fine ...
did anyone managed to download a rom called "sva rom for n9100" its russian rom with int languages , its perfect, i cannot download it ...
search google
I have tried to but i can only find it as paid for. Not doing that for sure. Have no problem with donating and will do so if i like a rom but no payment up front for me.
Yes I will try it out if I can find a copy.
Theres also a rom by a user named bawffg85, you can search the forums in here.
Thanks, came accros that one a few days ago. Still in beta. Monitoring that tread but there is little activity.
same problem here!
Hi, i'm a new member of this community and i'm here 'cause i've many problems with a samsung NOTe 4 SM-N9100 (HK).
here a list of the problems:
-i can't flash any stock rom.
-maybe i can't get root permissions (i haven't try because the phablet have a warranty but i don't want to use it)
-i can't make an hard reset and when i make it, when i restart the mobile i find all data, mail and password unmodified
-i can't delete anything permanently. after a restart i find all what i've deleted.
-sometimes, the phone freeze and restart...sometimes 2 or 3 times in a row and sometimes 1 time a day. i suspect i'ts a lollipop's update problem but i don't know...i've read something about this problem in internet..
i accept ALL of your suggestions: root, reflash, change kernel (if possible).
please help me.
And i'm very sorry for ANY language/grammar error. i'm italian... :| i really hope you understand what i've said.
thanks for all in advance!

i have same issue here, did you find any solutions ?
AFAIK when you factory reset your phone etc. if rooted you must remember to go back into Developer Options and re enable OEM Unlocking. This depends on the method you used to root, if you flashed dm-verity then you "May not" have this issue but cannot say for sure.
If it is already too late for you then I think you need to flash stock via Odin, plenty of threads out there on where to find the firmware (SamMobile) and how to do it. Even a quick google of the error gave me plenty of results...
One thing I have read is that you may have to keep trying to get your phone into download mode as the timing is much stricter with this error message.
I've the same problem with my g935x blocked on FRP when ii treid to root if any one can help .plz

@djluisbento This method seems to be interesting. But would you please clarify more about it. How to install the apk file on official recovery? Or it's enough to have the pendrive connected? And if yes, when this step should take place, after flashing the official ROM or when?
I'm stuck in a boot loop into recovery mode with dm-verity error, and unfortunately I have the FRP locked, so I can't install TWRP to flash the no-dm-verity.zip file to skip it.
Appreciate your suggestions.
I have the same issure. stock firmware wont install either. im just stuck on the FRP screen, cant even get into recovery
Same issue here, please help
Everything was fine with rooting and installing TWRP. after that did a restart/ attempt to goto twrp recovery, from then the s7 edge is stuck at "Custom Binary Blocked By FRP" and doesnt boot. please help!!
Have you do a Wipe then Format Data.
Then flash the no-verity-opt-encrypt zip in TWRP
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
If you want to be rooted with SuperSU:
Download the latest SuperSU by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
If you only want a bootable system partition or writable data in TWRP:
Download the latest dm-verity and force encryption disabler zip.
Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.

Had that problem with a brand new phone, just wanted to get into download mode to see if the phone was tampered with and boom, flash screen with the red warning, flashed stock KSA (phone original CSC) , worked and phone was formatted, another surprise was faced, google did not accept my gmail account, had to shut down phone for 72 hours as read in my google search for people encountering same issue, once the 72 hours passed I was able to sign in and using my phone again.

Yes, flashed both Zips in recovery. I used my regular google account during the initial set up. If i wait for 72 hours, will the phone just boot back online just fine? Still, how do i make sure it wont goto the FRP lock again while trying to reboot or reboot to TWRP?
Solved,
Flashed with stock firmware, logged in with same google account, rooted with TWRP, installed Zubi's sound mod. Made sure to keep the 'OEM Unlock' stay turned on.

Helo
But U did this after 72 hours?
There are several methods depending on firmware version installed on your phone. Basically you have to enter in your phone, launch chrome, install an app which gives you the possibility to log into your google account from chrome and not set-up program.
I used successfully the Bluetooth method. Search for with google. You need a bluetooth headset and follow the steps described on youtube.
BTW. My phone was brand new and I flashed different official samsung firmware ( csc). I had to change google password in between and that resulted in FRP lock....
The wait time is 24 hours as is stated in google docs from site

Hello I have a related problem, opened a new thread, but my thread was closed, because my problem is related to this one, but more complicated. I have the same problem with FRP lock as described here, I can turn on the download mode but it wont be recognized by my computer. I tried different usb cables, drivers, even computers, it wont help. I cant flash it with odin, smartswitch, kies, no matter what I try. If I go to recovery mode it says `dm-verity verification failed...`and if I choose `apply update from ADB or SD card` it says `update from external storage disabled`. I dont know what to do anymore Its a new phone
FRP Block - no Dev Tools enabled
Hey guys,
you're my last resort, I've tried everything I happened to come across, to no avail.
First off, I did something incredibly stupid, don't even ask me why, as I have no idea what the heck drove me to do this in the first place.
Anyways, I was using the stock ROM on my S7 Edge, not tweaked or tinkered with besides the usual CF-Auto_Root. It never caused any trouble whatsoever. But for no reason at all this morning I decided to disable USB debuggin and OEM unlock. A short while later I rebooted my phone, which ended up in "Custom binary blocked by FRP Lock".
I gave a factory reset a try, but that obviously didn't change a thing. So I went to sammobile.com and downloaded the latest official stock ROM for my device and tried flashing it with Odin. Unfortnately Odin always fails with "Complete(Write) operation failed.", which I assume is because I messed with the settings in dev mode.
Next stop: ADB. I've never used that thing before, but I thought I should possibly be able to get it done following a simple guide. Unfortunately ADB won't even list my device when typing "adb devices". It's just an empty list.
So please guys, give me some tipps on how I can bring my phone back to life.

I really need some help please. It's a month I am in trouble with Galaxy S8

Hello all,
My odyssey with the S8 continues.
I tried to do a rollback to stock rom android 8 and I broke nox apparently.
I am tried to reinstall again using this guide on the forum https://forum.xda-developers.com/galaxy-s8/development/rom-galaxy-s8-t3749171
but apparently my phone just doesn't want to run android 8, its stuck on android 9.
I then reinstalled android 9 downloaded from samfirm.
all ok except i found out google pay doesnt work anymore, althought the rom should be the stock one.
I tried to follow some guides on there again to fix this but my knowledge is not that deep to be honest.
Is there a clear guide I can follow to truly flash a genuine version of android 9 on my S8 and have google pay working again please?
Device is an S8 originally from O2 (O2U carrier)
Many thanks for all your help I really appreciate every efford.
Kind Regards,
Adelio

1. From the link provided you cannot downgrade firmware firmware with lower bootloader versions which is why it didn't work.To downgrade you will need the same bootloader vesion ( 5th number from right of firmware name).
2. Using samfirm or sammobil or updato (websites) firmware won't trip your Knox.
3. As for Google pay ( I don't use it ) the issue is not Knox related.Something's to try:
- In recovery clear cache
- backup phone and factory reset.
Not 100% sure but I think Google pay rely's more on safety net ( and maybe Google Play store verification ) so that maybe something else to check.

Samsung Galaxy S8 SM-G950F BOOTLOOP Odin Fails to install old BL

Hello Everybody,
I am an old iPhone user, who just switched to Samsung Galaxy S8.
I am used to simple Jailbreak one touch jailbreak, but this android is a WHOLE new thing for me.
I would like to root my phone with a ROM, which do not have KNOX and found WCKD on YouTube, which makes awesome guides regarding S8.
Problem is now, that I follow his guide "HOW TO INSTALL TWRP & MAGISK ROOT on Samsung Galaxy S8/S8+ | UPDATE 2"
and everything went smooth until I needed to reboot my phone.
Now my phone stays on the Booting Screen showing Samsung Galaxy S8 and I cannot get into my phone.
I then found another guide by WCKD "Galaxy S8/S8+ Odin FAIL, BOOTLOOP, BOOTLOADER FIX!"
But this time it did not go smooth, every time I go to download mode, then press Start in Odin and then directly hold down volume down+Bixi+power bottom it will not success, so I am failing all the time, same thing happen for a lot of other people, since they had commented his video. For some it worked but for many they have same issue as me.
What will be my next step here?
If I hold down Volume up + Bixi + Power bottom nothing is happening
If I hold down Volume down + Bixi + Power bottom I can come into "Downloading"
I really hope, someone can tell me what to do next, so I can use my "New" Samsung phone.
Update
I managed to fix the last phase before installing a new ROM without KNOX.
Would my next step be to download a ROM without KNOX, and the install it through TWRP?

1. In Odin under options untick auto reboot. It will prevent the phone from reboot when flashing is completed. Reboot manually.
2. For custom rom search

How important is it to flash the Kernel?
I did flash my phone with AMBASADII ROM FOR S8 & S8+ [ODEX] [AQH3] [v1.4]
https://forum.android.com.pl/topic/322837-rom-ambasadii-rom-for-s8-s8-odex-aqh3-v14/
It states fully knox removed! (rom not support: samsung pay, samsung pass and secure folder)
● Support models: SM-G95xF and SM-G95xFD
But after I flash the ROM and it got installed my phone still have KNOX 0x0 instead of 0x1 which makes no sense since I have TWRP installed on the phone.
Is it possible that ex. this ROM is so old, that it can not remove the KNOX security from a Samsung Phone?
Would love to get some recommendations about which ROM I could flash with so the KNOX 100% will be deleted.
Also would be happy if someone could explain me how important it is to flash the Kernel, and what I should look for.
Cheers!
Update 3
Today I flashed my Phone with [ROM] [PIE 9.0] AMBASADII ROM FOR S8/S8+ [STABLE] [ODEX] [DSD3] [v9.0]
in the Description it clearly states that KNOX is removed.
Knox and FOTA removed! (rom not support: samsung pay, samsung pass and secure folder)
https://sites.google.com/view/ambasadiidev/strona-główna/ambasadii-rom-for-s8s8
But it is not, when I go to Phone info I see this information.
Version of Knox
Knox 3.2.1
Knox API Level 27
TIMA No Poicy Version
Am I doing something wrong when I am flashing the ROM? I am using TWRP to "Install" The ROM.
Do I need to do something after I flashed the ROM? Maybe some kind of Kernel?
Thanks in advance.

[HELP] Samsung SM-G950F system & Os recovery ?

Hello,
Here is my problem.
2 days ago, I wanted to root my phone to get rid of any Google stuff (at this point I didn't know the existence of ADB commands :crying: ).
I followed a step by step youtube tutorial (youtube.com/watch?v=ZD-5twDm6XI), which works with TWRP, magisk and Odin (factory reset is needed).
Once everything is finished, my phone is finally rooted, and I grant superuser rights to Titanium app to uninstall google, and only SOME apps uninstalled totally (maps, chrome, facebook) BUT google play services won't uninstall. So, I try with System App Removal to uninstall google play stuff, and the same happens.
I reboot my phone, and it seems that everything disappeared... Not so sure... Indeed, the play store reinstall all applications as soon as I connect to the WiFi! and I have a persistent message "google play services stopped" that prevents me from browsing for example.
At this point, I use ADB commands, to remove anything which contains "com.blahblah.google.blahblah" and the play store (com.android.vending) with -k command. And it worked totally fine !!!!! I disconnect my phone, ready to backup my data. Idkw, i wanted to uninstall system app removal. IMPOSSIBLE from the phone, which says : "samsung One UI stopped" (I was in safe boot mode). My phone doesn't answer, so I reboot it.
Once it has booted, the TWRP menu screen appears. Ok, isn't that weird ? I swipe to allow changes, then I go to system to boot "normally" my phone.
A warning says : NO OS INSTALLED !!!! I don't understand, I panic, but finally boots my phone. Black charging screen. Forever.
I started first to flash an "official" Samsung ROM from Sammobile. TWRP indicates it is an invalid .zip, adb too. Odin doesn't manage to boot from the ROM too. I take a deep breathe and cry. Then I download the /e/ ROM which works fine !! but it has become impossible to backup my data from my samsung account....
So, I came to ask you a few things. WHY did it happen ? How can I be sure that there is no trace of TWRP anymore ? However, my phone storage is 64 GB and there is only 53,5 Gb free of internal storage !? Do you think the original firmware could be "hidden" in my files (e ROM is about 800Mos compressed) ?
It is stupid, but after my mistakes, I miss google...
I will do my best to reply asap.
Thank you for your help !
PS: -I'm a newbie in informatic, don't make things too complicated
-sorry for bad English, not my mother language
Google writes and distributes android.
There are many things in android that you cannot remove and still have a viable system.
imho you will have to flash a rom but we need your phones information (found in settings/system/about phone) model, version baseband, etc. etc
Others more knowledgeable can step in and help.

Thank you for your reply ! I've read your article about FRP but I'm afraid it's not my problem...
Here are some of my phone specifications :
model : SM-G950F
version baseband : G950FXXS8DTC1
OS : /e/ version 0.9-p-dev-dreamlte (LineageOS API : Ilama 9)
Android 9
I've been digging the web for ROMs but each time I feel unsecure about it (virus, etc...) so I hope maybe you have something trustworthy

/proc with ... 236.9GB but every under-folder is empty... (explanations welcome !)
/storage is empty
If anyone could check on his device (S8 Exynos with android 9.0 Pie and One UI) if the files' sizes approximately matched, it would be great !
The one I just received is G950FXXS8DTC6 / G950FOXM8DTC1 / G950FXXS8DTC1 (after it took the Apr 1 update) so probably identical - a Yateley GU46 6GG UK phone. I am running it on ATT Prepaid(US) , which gave me the Apr 1 update. I don't know its history but it hasn't been modified - knox=0.
What you would need to do is get that zip and flash it with odin, but having no experience flashing the S8 myself, or any idea where to get that zip, I can be of no help to you. (I just came off a moto x4 which I ruined by flashing a couple custom rom's to try to help others on that forum - the blessings of Pie on that device!)(plus, taking the Apr 1 update on that phone requires a factory reset/wipe.) I needed a dependable phone here and in Europe on vacation.
Keep posting and ask someone to help you re-flash it.
EDIT: I wonder what a settings/general management/factory reset would do. But don't do one until someone here much more experienced with the S8 suggests it.
EDIT: WARNING WARNING WARNING -> Before flashing, ACTIVATE PIN in "Secure startup" (You'll be asked for it AFTER flashing!)
lockscreen and security / secure startup / require pin
I also see a note to delete your google account before doing this. Don't know if necessary.
EDIT: I believe I have found the rom - see pic This is from the SamFirm exe. 0.3.7 I put VOD for the region.
Remember: don't do anything with this until someone experienced in S8 tells you to!
Hi KrisM22,
I've already flashed with Odin, and I have talked about this on different forums, seen tutos on websites,... I hope this time it will work
I have the ROM required, selected activate pin, followed step by step the recommendations, and if I figured it out I will keep you up to date !

I flashed a ROM from https://www.imei.info/download-firmware/samsung/samsung-g950f-galaxy-s8/SM-G950F/ , then I just followed the steps and flashed with Odin. TWRP has disappeared (the classic recovery menu came back). I think I have found my issue with the "no OS installed" bug : it could be because I deleted the essential API com.google.android.packageinstaller, what may have prevented the phone from booting and launching the OS and its apps .
I should have read this excellent post before...
*I ran antivirus analysis with virustotal and Bitdefender, which both declared the extracted files were safe : I didn't notice anything different by my phone compared to the original OS too, so...
