Magisk breaks password unlock? - Android Q&A, Help & Troubleshooting

Dear Android Community,
Disclaimer: I am new to rooting. Pls consider that & be patient. I might not understand everything in the first place :angel:
Okay - let's go.
1.) First off I installed the latest original firmware for my Samsung Galaxy J6 (SM-J600-FN)
2.) Then I installed the correct TWRP-version for my phone hopefully (TWRP-3.2.3-TwrpBuilder-j6ltedx-2018-08-21_14-15.tar)
3.) After that I used the standard Magisk rooting method by installing
no-verity-opt-encrypt-6.0
RMM-State_Bypass_Mesa_v2
Magisk-v19.3
4.) Then I installed Magisk Manager after my system booted for the first time and I am ready to explore everything rooting offers to me <3
BUT
What happened to me more than 5 times now. I installed everything I wanted, mostly rooting apps, Magisk modules & debloated my phone. My last step used to be to set a password, because I didn't want to always type in my password cause of the many reboots I had to make...
THAT HAPPENED
After I set my password, no matter what action led my phone to turn off it's screen, it told me to access my password & the result is still very frustrating because it said that the code is WRONG everytime?! How can that be I thought. First of all I thought I made a stupid mistake & couldn't remember it right...
BUT
Immediatetly after I typed the CORRECT password (I did this method min. 5 times, including installing original frimware with Odin or through installing my OrignialBackupFirmware through TWRP, so I know now, It's not my fault. It must be something else) the lockscreen said it was uncorrect and my phone put itself in a...
BOOTLOOP
This bootloop is different from what I've seen before, because it starts with the Samsung logo. Shows the lockscreen for some seconds (I can't enter my password from here) and starts to loop again. But from here I fortunately can get into TWRP recovery without having to install the system again with Odin.
THEN
I thought it had something to do with the software I installed, with magisk modules or with debloating, but now I've figured that this wasn't the case.
EVEN
When my system is just freshly rooted and everything is untouched this bad error happens.
NOW
I want to ask for help because I don't know how to solve this issue & I came across this post, where it says that I should delete following files:
password.key
pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal
...but I don't want to risk encountering this roor again, because I want to spare time, energy and I am wasted from installing & rooting & configuring my system over and over again...
Thx for helping me!!
Your John One ^-^

[Q] Samsung Galaxy Rugby: various issues

Hello all,
I'm sorry, but I couldn't find any device-related subforum for the Samsung Galaxy Rugby (GT-S5690M). If my questions are in the wrong section, please move it to the right place (mods)?
So here's the story: I just got my first smartphone. Since it's locked to Bell, it has some bloatware and need for sim-unlocking. I did a lot of reading and through some tutorials I managed to root Android and got rid of some bloatware (just four Bell apps). So far so good! Then I tried to unlock the phone. There are some apps in the Google Play that state that they can unlock the phone for free ("works on various Galaxy models").
I tried them out, but none of them could provide a solution. The last app I tried (Galaxy_S Unlock) requested that BusyBox were to be installed, so I did. During the installation the app remarked that already some BusyBox version was installed, but not the version that it was trying to install. I was suppose to try another type of installing (I used the normal/safe mode). But it said it was already installed, so good enough. Right? I tried the unlocking app again, but it still said it had errors getting to communicate with BusyBox. None of the unlocking apps gave me the impression that they changed anything in the system.
I figured that maybe a reboot of the phone would fix this. However, now the phone got several issues:
- booting takes forever (18 minutes) It does the animated Samsung logo (though, not with sound any more) and then keeps on slowing the glowing Samsung name.
- the speaker doesn't seem to be working at all
- it can no longer check for updates. After agreeing with the disclaimer, it says it can't connect.
- Samsung KIES (PC software suite) doesn't see the phone any more.
- the phone is generally very slow now. Even when typing a password the phone sometimes hangs for about 5-10 seconds. Loading the disclaimer for the Software Updater takes 10-15 seconds.
I tried to reset to factory defaults and reload the rooting zip file again, but to no avail.
I've been trying to read up on the isolated symptoms, but I'm simply starting to feel overloaded with all the info, especially since I'm a Android newbie.
Does anybody recognize these symptoms and, more important, has any tips on what to try to restore whatever has gone wrong?
Additionally, I would really be interested in knowing if there's a way to force-upgrade to Jelly Bean. It appears that this firmware hasn't been made available to Rugby users yet through the regular update channels. But are there alternatives?
I have a Bell as well

The external drive will only work if you select "Enable USB Connection" in the Android menu.
I've revived my phone for a hobby project. Can't remember how I solved the above issues at the time, but it doesn't want to accept the stock firmware image. I can only find one old version on my external HDD with old backup data. Tried several Odin versions to no avail. 3.07 stays stuck at "SetupConnection". 3.04 fails with "Complete(Write) operation failed."
Galaxy Grand Duos
Please padone me for posting in the wrong LOC. It just that my Phone brake down,N I forgot my old XDA account password I had to Create a new 1
Now here is my Q: my galaxy grand dous GT-I9082 just is now on Boot Loop I can't write down any detail about the phone cose it can't boot sorry bout that. Now I boot into CMW then I mistaken navigate to Mount & Storage then On FORMAT SYSTEM after it successfully formated the phone can't boot it stock on the GALAXY GRAND GT-I9082 logo please I need urgent help please it really annoying I had to crearte a new XDA account cose of my phone

What worked for me to fix: The frp lock Soft-brick (using Samsung Smart Switch)

This will save you 8-12 hours of your time if you are lucky. This means that it also includes the meaningful links of 8-12 hours of searching. Sentences in italic are important. 1 link is for the Odin official website, the rest are re-links back into XDA.
The device in question is a SM-925T Tmobile S6 Edge.
The problem was this. I rooted my phone and messed around with Greenify and the Play store. To prepare for rooting, I allowed unknown downloads, unlocked the bootloader, and turned my security lock off (I had set it to a finger print lock). After I was done rooting, I immediately locked the bootloader again(<--A mistake that caused my bootloop/ soft-brick). After I was finished messing with the above apps (Greenify, etc), I wanted my phone to restart. So I held the Power button and selected restart, while I was on the lock screen (may not be important). I noticed that it took a long time to restart, and upon closer examination, I noticed another error under the "kernel is not seandroid enforcing" (which appears to be natural for rooted phones). The error was "Custom Binary blocked by FRP Lock". It was a new error. I investigated this new problem using the internet , and this dude was panicking like hell, but he didn't appear to fix his problem. He did hint that returning to the bootloader to its locked state was a mistake. Looked a bit more and this guy pointed to another thread, which introduced me to flashing and more importantly his fix, which was to flash the stock 5.1.1 image through odin. He used this link, which contains all the stock firmware for the majority of the new Samsung S6 and S6 edge versions. To make a long story short, most of these fixes involved flashing your firmware to the stock version. So I went to the Odin Website, and downloaded every version, as a couple threads have said that different versions worked for them. Here is a thread with everything you need for Odin. Now, after sorting through and finding micro USB cables that are detectable by Odin, an important step because Odin might develop a pattern of detecting then failing to detect your device through that cable, and testing all the usb 2.0 ports, I was ready, and had Odin with my stock firmware. Odin kept saying "NAND Write", then in the next line "FAIL". This was annoying as Odin wouldn't detect my device again unless I unplugged it, restarted it to download mode, then restarted Odin before plugging it back in. I got confused and found links for somehow fixing the .tar files, stock roms, .pit files (DO NOT MESS AROUND WITHOUT KNOWING WHAT THOSE THINGS DO), and other threads/websites that say to boot into recovery mode , factory reset, then wipe your cache. I could only do that once. After me messing around with all of the above file variants and supposed fixes to help with my issue, I couldn't boot into recovery mode, it got stuck on the "Samsung Galaxy S6 Edge" logo. It did not fix the NAND write failing. There however, are a lot of websites allowing you to download stock software for your phones, and I don't think I can link them as it might break a rule. Surprisingly, some have claimed that using a stock file for another device worked to fix their problem. This thread, which convinced me to use Smart Switch when it failed for everyone else, was very useful, although I recommend downloading Smart Switch from the official website of Samsung. None of the Odin flashing had worked so far, including the Roms and .pit files so I tried Smart Switch. I opened it, and upon selecting the "more" tab on the upper right corner, a bunch of tabs drop down. One should be "Emergency Software recovery and initialization". I had to find my S / N (Serial) number, and I was very confused on how to obtain that number as I was locked out. But to obtain it, do the same process to boot into download (hold volume down, home key, and power key), but stay on the prompt and don't go to the screen that has the word download in the middle. Don't do anything other then reaching the prompt confirming if you want to install a custom ROM. Then, press the home key and it should show your S / N number along with your IMEI number. Once I imputed the code I saw on my phone into Smart Switch, it told me to connect the device. Now, by this time, I realized that Odin only detects my device if it is actually in the download screen. Why shouldn't my computer? I booted into Download on my phone and followed the steps on my computer, making sure that the computer can recognize my phone while it is using a valid USB port and Cable. And after some waiting, for me, my problem was fixed and I could use my phone again, it reverted to it's out-of-box state. I hope this drawn out but very specific explanation helps you guys. It's my first post And also, this thread confirms that you can use a USB hub for flashing(at least for ROMS), Smart Switch, and for rooting.​
Thank you for this detailed account, however nothing of the above has worked for me. Odin won't flash the firmware of 5.0.2 (and I tried 5.1.1) and Smart switch does not recognize the device to do anything. BTW phone has been rooted for months and last night decided to turn on its FRP lock randomly and now I'm stuck. Any help would be greatly appreciated.
Explain throughly what you have tried. Especially different ports, cables, and computers. Did you have the right device drivers? Did you do anything else?
I followed your footsteps and and the step where it has to show me the S/No and IMEI, it only shows IMEI number. I am unable to find the S/NO any suggestions?

press vol down home keys and power key once you get to the first blue screen release vol and power keep holdind home but I already tried smart swich didn't help
5.1.1 has FRP lock auto turned on whenever you have a google account on the device... This is probably going to cause a lot of problems with all newer devices that get rooted. I even tried removing all google accounts, flashed recovery and flashed boot img back to stock after rooting and still FRP was bricking the device. I got supersu onto the device, all working fine for a 3rd time, as soon as I added a google account onto my device and restarted, it was FRP lock blocked and soft bricked again.... I used kies to restore to factory again, re-rooted it for the 4th time when I finally discovered an option in developer options called OEM unlock, Turning OEM unlock on turns off the FRP lock security feature.
My conclusion, If your going to root 5.1.1 make sure you remove all accounts from the device first, do not change google passwords for 72 hours prior to rooting, once rooted, YOU MUST TURN OEM Unlock ON in settings>developer options before adding any google accounts to the device.
Hi everyone!
I also got a Samsung S6 Edge + from a friend with custom binary blocked by FRP. I don't know what he was planning to do but I guess it was rooting.
He said he want me to backup any files before I try anything. Don't know how to proceed. But as suggestion, I want to ask if using "fastboot oem unlock" command would fix that.

I'm pretty sure fastboot isn't for Samsung devices. Hard to back up any files u less you can get into TWRP or the phone. If you flash stock firmware is highly likely the files will be wiped

There is no TWRP recovery on the phone. Yeah you're right about backing up files. I don't even know how to proceed and I can tell you I have huge experience on that stuff, rooting flashing custom recoveries and roms, etc... but in this case, I can't say if files can be backed up.

The only way is to 're flash the exact same firmware he is currently using now using the 5 files firmware package. But yo ensure csc_home is used so the data will not be wiped.

Thank you for you reply.
Please can you tell me where I can find such software or how to do it clearly! I know how to use Odin but I don't know how to exclude user_data to be wiped. Thank you

Thank you thank you thank you!!! This is exactly what I was looking for I had just rooted my note 4 running 6.0.1 and had no idea what the oem option was as no rooting method talked about it at all so naturally as soon as i added my Google account phone restarted and locked up.
Kies was the answer I needed as frp lock was active in download mode and my factory reset in recovery failed everytime but running Kies firmware upgrade and entering my model and serial number it installed perfectly in download mode with frp lock still active saved me alot of hassle ?

Rooting/Rom Unsuccessful (Bootloop solved SM-G925F)

Hi. I have spent the past 10 hours trying to root my phone and install an XtraLite type of ROM because I am so sick of have 75% of my RAM used up when I haven't even started using the phone. I softbricked my phone, and after hours of trying to solve every minor issue that came up I finally found a solution and managed to flash a stock ROM. I have a lot of questions that I would love to get answers to because I am a little bit confused right now.
My history.
Bootloader
I spent so much time googling this and I decided to trust one site that said, if you can't find the "OEM Unlocked" option in "Developer Options" then your bootloader is probably already unlocked. This was the closest I got to an answer, along with many people with SM-G925F saying the root was successful for them without doing something to their bootloader. Can someone please clarify what I need to do with the bootloader with my EU SM-G925F?
Flashmode/Download Mode
Prior to this I spent very long trying the "adb-windows reboot bootloader/flashboot-windows oem unlock" without any results. However I somehow came to the conclusion that "Download" mode for my Samsung was no different. Any clarification on this subject please?
Rooting
The first rooting guide I trusted was the CF-Auto-Root page. This is where the bootloader question was raised but as I came to the conclusion that the bootloader already was unlocked, I decided to give it a shot. I downloaded SM-G925F file, added it to AP on Odin, and flashed my phone. Now my phone was locked in a bootloop. According to CF-Root page "A modified recovery and cache partition will be flashed, which will install (only) SuperSU, then clean-up the cache partition and re-flash the stock recovery. For the root to work, the device must reboot into recovery. Most devices will do this automatically after flashing these files, but in case that does not happen, please boot into recovery manually.". As you probably guessed, my phone never booted into recovery mode, and I was never able to manually do it either since the phone was in a unstoppable bootloop. Did I do something wrong here or misunderstand anything?
ROM Instructions
My first choice was: http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
I failed the first step, never even managed to root with CF-Root. And regarding TWRP, I did download the correct version "twrp-3.0.0-0-zerolteeu" I assume. However, many descriptions say my phone needs to be rooted before I can install TWRP so I never tried to install it. Even if, I couldn't find a detailed enough description of how to install TWRP. All it says is "flash it". Problem is, I am not sure if I am supposed to be in "Download mode" and use Odin loading TWRP into "AP" or how does this work?
Never got to the ROM installing, but it would be nice to have something more detailed than "Put it on your phone, install it". Like, do I enter recovery mode and navigate to the rar file and chose to install it? Not sure how this works.
My solution to bootloop
This part took me the longest. For those stuck in a bootloop. Holding DownVolume + Power button for at least 15 sec will simulate disconnection of the battery. This helps you turn you device off. Also, if you nothing happens, make sure you unplug the USB cable as it keeps trying charge and show the status it tries to boot and keeps looping as a result. I could always manage to get into "download mode" through DownVolume + Home Button + Power Button no matter what, and I am grateful for that. I managed to find the exact build I was using on my phone "G925FXXU3COJ1_G925FOJV3COJ1_G925FXXU3COI9_HOME". But everytime I tried to flash, it always failed in the end. I spent hours on google. Someone mentioned something about it failing on a certain point of the writing, involving hidden.img. I googled for info on how to resolve this, and someone suggested to rename hidden.img to hidden.tar but it did not help. I also read some threads regarding using a matching PIT file and there were about 7 different ones to chose from. I tried them all without success. Finally I read something about removing hidden.img from the ROM. I renamed the ROM from .tar.md5 to .tar. Unpacked it, and then repacked it without hidden.img using tar-Tool from these forums. The following flash of the new created tar.md5 (without hidden.img in it) was successful.
Slave for stubborness
Unfortunately since I spent so long getting through this horrible experience, I would feel bad have wasted an entire day just to get a phone that is now reset. I could have done that in 30 seconds. However I am persistent to get this working and I am truly grateful for any help you people can supply my with. I did manage to root and ROM my old S3 but that was a while ago and I only remember a few small things about Odin and so forth. However things seem much more complicated now than before.
Thank you in advance,
Alex

[HELP] S4 stuck booting after kingroot then knox removal

Hi For my 1st root I decided to use kingroot due to the simplicity for my S4 GT-I9505. Carrier Optus & version 4.x (think might been 4.2.2) So yesterday I tried the APK root which failed so I tried the desktop v3.0 which also failed. Realised my antivirus might be messing with it so disabled it then tried again. Got stuck at 97% for couple hrs. Forced reset & it started normally. The kingroot app said no root but I had root access for programs & root checker said success when I allowed it. Attempts to update the supuser on kingroot website & rerooting with the program still failed. I thought I had removed the knox app prior to root but got random (successful) restarts. Found a thread saying it was cause knox was still active. So used sdmaid & this thread (http://forum.xda-developers.com/showthread.php?t=2514703) to remove all traces. All removed 2 knox files with same name as apks but dif extension that weren't on the list. Think they were something like .ocex. Did a device restart to make sure was gone but now wont boot. Goes through the s4 startup, then the carrier screen then gets stuck on the samsung screen after that. Tried holding the vol down for safe mode with sd card in & out from the 1st samsung screen. Going into recovery takes me to kingroot recovery v0.0.0.2 in Chinese. I saw the word cache in there so I reset cache & it made no difference. Kies 3 wont recognize it. I thought I had made a backup prior but it had failed miserably so I got msgs, call logs etc but not my media files like photots. If possible I would like try options that dont wipe my personal files 1st. I have no idea how I should proceed or what the Chinese says in the kingroot recovery mode. Any help would be much appreciated.
Does anyone know the kingroot recovery options? I read sometimes a hard reset can wipe the apps but leave personal files. Even if I loose them better than not having any access into the phone. I am also able to boot into load custom os menu.

Samsung Galaxy Tab S6 Lite (LTE) Bricked? Bootloop HELP

Hello, I am new here and I made a huge mistake!
I purchased Samsung Galaxy Tab S6 Lite (LTE) literarally 1-2 days ago and I wanted to root it, I had my smart phone rooted which did not have Knox protections, it was as straight forward as flashing TWRP and use Magisk via instructions I followed.
I make use of "Root" privileges a lot when using my device, I find it very important to my daily life so I decided to risk rooting it, after doing so my tablet was showing 2 errors, that its not using official samsung software and that the boot loader is unlocked, when I unlocked the boot loader using OEM Unlock everything went fine, the option was greyed out and checked afterwards.
During the boot process, it reboots 2 times and it shows a integrity error, integrity and some very long number, I am assuming its a integrity check? I have the exact matching firmware, so I flashed back the stock firmware and... the "not using official samsung software" warning disappeared, it boots me into recovery mode, I choose "reboot" and the device goes to boot looping with the same error.
I was following this tutorial: https://forum.xda-developers.com/galaxy-tab-s6-lite/how-to/howto-unlock-root-galaxy-tab-s6-lite-t4132289
But there are some things I skipped, here the exact steps I took:
Unlocking Boot Loader:
Followed all the steps from 1 to 4 but I skipped the 5th step entirely, the step where it asks you to mess with firmware date and twrp, I did none of that, I will mention that when I was looking for stock firmware to download before doing anything, I was not able to understand the CSC so I didn't know which firmware to exactly use until a software update came up which told me the exact firmware, I accepted the update and download that stock firmware, because my firmware was updated I didn't think that following the few steps of the step 5 would've done everything as I was already off the path.
I didn't do the 6th step as I just checked of the OEM Unlock is greyed out and still checked in the "developer options" section, I assumed that it was a success, not to mention the boot loader unlocked warning that was showing up and yes, all the data was erased and was forced to go through the setup process again as expected.
Root the tablet:
1. I have downloaded the firmware as it says not just for the purpose of rooting, the firmware that the software update told me about, this is the firmware I downloaded, the firmware is a exact match, everything is matching: https://samfrew.com/download/Galaxy__Tab__S6__Lite__-LTE-__/xs5l/SEB/P615XXU3BTI3/P615OXM3BTI3/
2. I follow all the steps from 2 to 11 from here.
3. When I reached step 12, I went to download mode and I look for any messages regarding it only allowing for official samsung images, but I saw no such message, didn't really pay attention to anything else, I just glossed over things, considering there was no such message I assumed that KG/RMM state was good, don't know what it was but it might not have been "prenormal" because there was no message regarding official samsung images, from here I falshed the boot.tar file like in the instructions, that lead me to my current problem I mentioned at the very start of this post.
4. There was no step 13 as I can't boot into android due to "integrity" error I have, right now I have my tablet turned off (thank god I can do that) via the recovery that shows up after flashing stock firmware.
Addition Info:
1. I don't have any data to lose, if I need to do a factory reset or something of that sort, I have no problems doing that.
2. As I mentioned at top, I do have a stock firmware downloaded from this link here: https://samfrew.com/download/Galaxy__Tab__S6__Lite__-LTE-__/xs5l/SEB/P615XXU3BTI3/P615OXM3BTI3/
3. The tablet is: SM-P615 (Samsung Galaxy Tab S6 Lite (LTE), I bought the LTE so I could use it as my phone)
4. At the download mode, the OEM (Boot Loader) state is set to NO and the FFS (I don't remember if its FFS exactly at the moment, something FF I believe, I don't want to turn on my tablet at the moment) was set to NO.
5. The KG (No RMM mention that I could see anywhere) state is showing up as "Checking..."
What do I need to do to fix my tablet? do I need to wait for 7 days? if so how do I do so, like does leaving my tablet off count or not?
PS: I am a self-thought experienced low-level windows programmer, I've been doing programming for over 10 years now, never have worked with Android development but I can attempt to build something from source if necesarry, I know very little about Linux OS as I purely work with Windows and use Windows for everything including servers.
I have done some research regarding that "integrity" error and I can't find any screenshot in google images that matches how it looks on my screen, but there are a lot of them quite similar to it, which basically says "verification failed, factory data reset your phone", in my case I don't have that message, it just says "integrity", but when the boot looping stops and shows that failure I do have 3 options, "try again" and "Factory data reset" and the 3th one I don't remember, I am suspecting that this could be my problem! I believe the samsung just changed the way that particular message is shown (visual change), so I just need a factory data reset and it will work, most likely with the rooted boot.img file! I will attempt this after a few hours of this reply, I may have panicked too early.
The issue has been fixed
Well this is surprising, I was about to do the factory reset but before doing so I decided to flash the same magisk patched boot.img file, when I flashed I saw seeing those 2 warning messages as expected, I was expecting for it to fail after 2 boot loops so I can do the factory reset as intended but on the 3th boot loop the tablet booted up! I was brought at the android setup screen, once I was done with that I checked the OEM Unlock, it was still checked and greyed out, downloaded Magisk Manager and to my surprised it worked! Magisk Root latest version is installed and working, it asked me to allow magisk do some "additional setup", the tablet booted up perfectly fine after that "additional setup", I check root privileges using "Root Checker" and it worked, I have root privileges! I most likely have panicked too soon, sorry for wasting your time! Hopefully this post will be useful to someone in the future looking to root their tablet.
My assumption of what happened: When I flashed the stock firmware AP a second time so I can turn off my tablet, it most likely did a factory reset without me knowing, so when I flashed magisk again before letting it try boot up again, the tablet booted perfectly fine because factory reset has already occured, which brought me to the android setup screen.
