are my files lost? can I recover my photos, phone numbers, etc. from this locked state? - General Questions and Answers

Hello,
My old Galaxy S6 Edge (T-Mobile) began giving me this warning:
Security error: This phone has been flashed with unauthorized software & is locked.​This happened after a low-battery shut-off of the phone. It was not in the middle of an update at the time.
I can get into recovery mode, but I don't want to reinstall and delete all the data (family photos, etc.) on this phone.
I have tried all the apps out there claiming to be able to backup a damaged phone (FonePaw, DroidKit, FoneLab, DrFone) with no luck. They did not work. After some research, it appears my only option is to download firmware from SamMobile (or Frija) and use Odin to reinstall.
However, I have seen conflicting reports that this will overwrite and delete my personal files! I want to avoid this, of course.
I read that as long as I am reflashing with the identical firmware originally installed on the phone, I will end up deleting my personal files. But I can't get into the phone to find what firmware version this is!
At this point I am stuck. Please help! Thank you.
I used the following information to bring me to this point:
My S10 has been flashed with an unauthorized software and is locked - Page 7 - Android Forums at AndroidCentral.com ​I saw that my S10 had an update, so I started updating my phone and a few moments later, I get this message with a green screen stating that my phone has been flashed with an unauthorized software and is locked, please contact my carrier. I had no idea what was going on, so I called Samsung and...

Maybe someone has a plan but I think you're boned. Those online recovery services will encrypt data found making it unusable unless you pay them. Never use them.
The data is likely way lost.
Google may have saved some of it for you even if you disabled Transport Services at some point. After reloading see if it will restore anything.
Same for Samsung backup.
Always redundantly backup critical data to at least two hdds that are physically and electronically isolated from each other and the PC. NEVER encrypt data drives!
If you don't do this, sooner or latter you will lose data. Been there, done that

Thanks, Blackhawk. I was afraid of this.
Is there any truth to being able to avoid overwriting data if the same firmware edition is installed using Odin?

I could be wrong.
If the data has been deleted it means the OS's record of it's place in the memory is deleted*.
Unless a separate app like Galaxy Store's File Guardian preserved it.
If you ran DrFone it's probably fubar for sure.
You can turn it off and research it more... nothing to lose except time.
*Even using the phone could overwrite the data as that memory space is now unassigned and freed for use if needed by the system.

Unless you can unlock the phone, it‘s hard to recover those files.

@sentdab
when you re-flash a ROM the partitions that holds the user-data aren't touched, unless you force a clean install. Typically user-data only get wiped if you do a Factory Reset.

So in theory I should be able to use Odin to flash *any* firmware version for my phone on this site https://www.sammobile.com/samsung/galaxy-s6-edge/firmware/SM-G925T/TMB/#SM-G925T without risk of deleting the user data (photos, videos, phone numbers, etc)? I downloaded the latest firmware package but it only contains one file:
G925TUVS6FRC1_G925TTMB6FRC1_G925TUVS6FRC1_HOME.tar
Which of the fields in Odin do I put this file in? BL, AP, CP, CSC? I am referring to a guide such as this one:
How to Use Odin to Flash Samsung Galaxy Stock Firmware
If you own a Samsung phone and enjoy rooting or modding your device, flashing official firmware can be very useful. Odin is Samsung's own internal program for loading such updates for testing purposes, and it's quite easy to use for your own custom modification needs.

Flashing a ROM on my new SM-G930FD

Hello,
I just purchased a Galaxy S7, and want to flash a rom to it to remove some of the Chinese settings and bloat. I've already rooted it (easy part), but I'm unsure about how to proceed. I want to make sure I have a backup of the original FW that I can put back on via Odin if something goes wrong, but I can't seem to find what I'm looking for at sammobile. I've attached all the info that I got from Phone INFO app hoping that someone can point me in the right direction. I'm most confused about the CSC, as I can't find anything with that same code. And it seems a lot of the others have the same PDA as mine.
For what it's worth, or if anyone can give any advice on customization; I don't care about the DUAL SIM feature (so long as it doesn't affect the microSD card) and would love to get the little "1" next to the phone calls and SMS messages removed.
Thanks in advance.

Hi. I'm no expert but here's what I believe are your next steps:
1. Using Odin you should install TWRP (for recovery). This is where you will install and uninstall most ROMS, Kernels, etc.
Before using Odin and installing TWRP make sure you unlock the Developer Options and activate USB Debugging and OEM Unlock.
2. With TWRP installed, you can now install any ROM. I suggest you install SupermanROM (it's fantastic and it has OTA updates).
Now for each of those things I've told you make sure you read their long instructions.
I hope you enjoy your S7 and the amazing SupermanRom.

Thank you for the reply. I have already installed TWRP and have all the files needed for Superman. At this point, I want to make sure I have the files needed to flash back to Stock in case something goes wrong. The problem is that I don't know which stock files I need to download.
u can always go back to stock.
1.) download SAMSUNG KIES
2.) open SAMSUNG KIES
3.) click tools , select Firmware upgrade and initialization
4.) Model Name : SM-G930F
5.) your serial #

I thought I seen somewhere that KIES no longer works after KNOX is tripped? If it does, I would still use 930F even though my model is G930FD?

Internal storage problem
I purchased what shows to be an unlocked Galaxy S7 32Gb (32GB marked on the back of the phone) - Model SM-G930FD - originally T-Mobile.
The phone looks immaculate and shows no physical signs of being opened or tampered with.
I have not put in a new SIM card or taken the phone to be activated on my plan yet. I did put in a 128GB micro card. (Q- I don't assume putting in a SIM card would resolve any of the below issues?)
In settings the phone shows to have 32GB internal storage and recognizes the MicroSD card, but when I connect it to my computer the internal storage only shows 17.5MB available... So obviously when I tried to load the Chrome browser (40+ MB) I got an insufficient memory message. I was hoping it was just reading the available storage wrong.
When I look at Storage under settings it shows that the phone has 32GB internal and 28.15GB available, and it shows 125GB available on the SD Card.
Some of the other info from my About Phone page:
Android Version 6.0.1

I tried resetting the phone and erasing all data and it is still the same.
Phone comes on and seems to run fine.
I can't even flush it, I tried rooting it with kingroot which was success, I installed superuser and twrp app which did not help as it can't find my device name under select your device on the twrp app, and when I try try to navigate the files to flush still no luck as I can't find those zip files.
Also when I try to do it manually by restarting the phone by v+, home and power button to recovery
I can't find install zip, it's just
Reboot system now
Apply update from ADB
Apply update from SD card
Wipe data/factory reset
Wipe cache partition
Apply update from cache
That's it
So before I put it up on eBay to get rid of it - is there anything I can do to try to release/recognize the internal storage??
Thank you in advance!!

Apparently, the device should be on the firmware it initially came out of the factory with. Since I flashed BTU, it is not accepted and one should go through Emergency Software Initialization and it will then work. I also have tripped KNOX, but I don't know if that's the reason. Please note that my device is fully official apart from tripping KNOX and installing the BTU firmware. Is there any workaround?
Update: Tried opening Secure Folder from the settings and is now getting this;
As you can see from the first screenshot, only custom ROMs and root is not accepted so it should work for me.

You've answered you're own question here really, you're getting these errors because knox is tripped, once knox is tripped anything knox related won't work even if you're on a stock firmware.

Thats because you got magisk and magisk hide plus the Rom has build prop edits to make things work. A known issue for example if you have knox tripped and you flash a stock nougat firmware shealth won't work because of tripped knox, only way around it is to have a custom Rom or root it and change build prop, nevertheless tripped knox is the underlying issue, anything knox based on stock firmware won't work if you've got knox tripped.
Stock ROM with Magisk Hide and the build prob modified with S Health working so it may also work for Secure folder.
Stock rom, root with magisk but before that with su... shealt never stopped working

How do I disable OTA notifications on a rooted S7 (android v6)?

On my S6, when it was rooted, OTA updates and all OTA notifications disappeared immediately.
But not the same on the S7. Admittedly I rooted it *after* the android v7 OTA update started appearing.
Now I see it in two places:
1) Under Settings it says Software update - tap here to update the firmware...
2) In the pulldown notification panel I see Software Update - download failed
What is the procedure for cleaning all this up? I am a hardware/software developer. I have e.g. Root Explorer, Titanium Backup, MyBackupPro, Disable Service... I have googled all over the place and found various things but none of them appear on my phone.
Actually I am not sure it is trying to download the updates. It may just be popping up the "failed" notifications.
I did clear the cache partition (power+home+vol up) but that didn't remove the nags and the failed update notifications.
I would really appreciate some help. Android 6.0.1.
Try clearing data from the software update apps in Settings > Apps > 3 dots top right menu > Show system apps > Software update (There are two) > Storage > Clear Data
If you cleared the cache already, you can hit the "Install update" button and it will fail as you already deleted the system update file
Thank you.
I cleared the storage for the first app, and the clearing buttons for the 2nd one were greyed-out.
The nags are still there. This time I have done screenshots:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What concerns me about the last one is that if I select Download it will probably download the OTA update and apply it, wiping out the root.
Incidentally, the Android Pay app still starts up, which isn't supposed to work after a root I have read about some root methods which preserve this but the procedures were complicated and I didn't apply it AFAIK. I used these:
OTA shouldn't download if you are rooted, it will fail
Are you definitely rooted? That's an old version of ODIN, should be using 3.12.3 or newer, I've not rooted mine but from what I hear *(Could be Nougat only) CF Auto root doesn't work, needs SuperSU zip flashed from TWRP
But like I say I haven't rooted so am not up to date with what does and doesn't work atm
Worst comes to worst, you flash Marshmallow stock ROM again and start fresh if it does update you to Nougat
There is root for Nougat too btw (Which model S7?)
Root Checker reports rooted OK. Root Explorer sees everything. So it does appear to be rooted, in the traditional sense. Titanium Backup also works as it normally does on a rooted phone (I also have a rooted S6 v5 and T705 v4.4.2).
The reason I didn't update the OS is because I have loads of apps installed and I don't want to lose the config. I haven't been able to find out what exactly disappears but there are widespread reports of the update losing lots of app config.
Do you think I should try the download and maybe that will fail and clear the nags?
The S7 is a UK official stock one, SM-G930F 6.0.1 G930FXXU1BPJJ.
Since I know how to wipe the cache, I thought it should be safe to download the update. Even though the phone is rooted, that did work! So I downloaded the 1.2GB and then wiped the cache partition. But the two nags (the one appearing under Settings, every time the app is started) and this one which appears when I click on the nag in the pulldown list (apologies for not using the correct terminology):
are still there.
What will be interesting is whether the big popup nag (which has been appearing many times each day, with the frequency increasing recently) will disappear. I have not seen it yet this morning...
Surely, on a rooted phone, one can drop in some file(s), or rename some files, to block the updates? There is a ton of stuff on this for previous android versions online but as usual most of it doesn't work on this phone - the files are usually missing.
EDIT: it must also be possible to set up a "lmhosts" file which blocks the Samsung update server domain. I found this
https://www.howtogeek.com/140576/how-to-edit-the-hosts-file-on-android-and-block-web-sites/
and it seems very simple. I just need to find out the domain The hosts file is under /system/etc. It contains just
127.0.0.1 localhost
::1 ip6-localhost
Also, this
https://source.android.com/devices/tech/ota/
suggests that renaming e.g. otacerts.zip would stop OTA. I have renamed it to otacerts.zip-bak and that has done something. The above screenshot still appears but after about 10 seconds! This is of little use so I renamed it back. I suspect that messing with the certificates file just prevents the update installing, but doesn't prevent the nag and the download.
The funniest thing is that I have a phone with full root access but Android Pay works. I have been using it all day today
Clearly, for an S7 with this specific firmware and using that specific version of Odin, this is what you get... Extremely useful.
Well, no more response here, but I fixed the main nag - the one in the pulldown list. I used this method
https://forum.xda-developers.com/verizon-s7-edge/help/block-nougat-update-t3581529
i.e. BK Package Disabler Pro and see posts #7 onwards. The one to search for was com.wssyncmldm and disabling that and rebooting the phone did it.
This is S7 (not Edge) on android v6 (lollipop I think it is called).
I still get the Software Update thing under Settings but it is dead - clicking on it does nothing so it is harmless.

Question Bootloop after removing com.android.location.fused [SOLVED]

I rooted my phone a while back but did NOT install TWRP. Using System App Remover (Root needed), I started removing all sorts of bloatware after a bit of research for anything that sounded important.
Now I'm facing bootloop after removing com.android.location.fused. A little research shows other people facing similar issues were able to fix it using adb shell and TWRP. So I looked up elsewhere and got TWRP up and running.
Basically, the method is this:
https://www.reddit.com/r/PokemonGoSpoofing/comments/b1njwr
But there is no users folder under system on my phone!
I figured it's ok though. Because removing system apps using System Apps Remover, apps are not deleted but rather placed in a folder somewhere in the internal storage (can't remember the default location and can't find it using TWRP File Manager either).
Now here are my questions:
1. Is it possible for someone to share their own version of com.android.location.fused with me along with the correct storage location for me to put it into? Would it work?
2. Could someone please tell me what I am doing wrong that I get no users folder under system?
3. Is there a way for me to restore my own version of com.android.location.fused which is located god-knows-where on my phone?
P.S. Tech rookie here; bare with me...
Did you tried mounting all on twrp? system partition, data etc...? I correctly see that folder.

I can try to send the apk, but I don't think it will work, because you need to enable the package again on /data/system/users/0/package-restrictions.xml.
If all fails, why not flashing stock rom using HOME_CSC instead of CSC so all data will be preseved?
Spoiler: home csc
HOME CSC​If your purpose is to just re-install the firmware or update your Samsung device’s software without wiping your apps, all user data, and settings, you should go with the HOME CSC binary. Choosing this file will only affect the software version of your phone while keeping everything intact.
Ehhh, never remove GPS location services! Clock go brrrrr!

Thanks for the quick reply.
Mounting all selectable (some are not clickable) locations still gives me no users under system.
As for flashing stock rom, based on what you are saying, I suppose I should select all other options (BL, AP, and CP) except for CSC (which I go for USERDATA instead) and for that, I've got to select HOME_CSC file, correct?

Yes, u need to select all in odin like u are flashing normally.
AP, BL, CP, and HOME_CSC
only use HOME_CSC instead of CSC
Spoiler: info
do NOT use the CSC tar, but instead use the HOME_CSC tar as we are performing an upgrade, not the initial install.
Don't know if it will work but is a try at least. Hope will fix

Thanks for the clarification. Definitely gonna give it a try. Currently downloading the latest from sammobile.
Will post an update in a couple of hours.
Ok, so I flashed the latest stock rom from sammobile and it worked; just as @Oneplus# suggested it would.
Still don't know why I had no users under system but I'm just gonna call it a day and leave it.

[HOWTO] Total Reflashing of the Galaxy Tab S6 Lite via NAND Erase and Re-Partition

If anyone needs to totally reset their Tab S6 Lite (2020 Exynos Version) with Odin, this guide should help.
​
Code:
**I take no responsibility for any broken devices!** While care has been taken to ensure the steps are correct, **you are doing this at your own risk!**
All files will also be provided at the end of this guide for ease of access!
What is NAND?
NAND and NOR are actually 2 main types of flash memory, that are related to computers, and it stores the BIOS settings to the ROM of a computer. Since Android devices don’t have a BIOS, flash memory, or NAND relates to the bootloader and OS kernel that work together to boot Android devices into the system. Being a non-volatile memory, it keeps the essential OS data even when your Android smartphone is turned off.
You cannot fix a Samsung device after an unintentional NAND erase action by simply flashing the stock firmware. Since NAND erase wipes all existing partitions from the device’s storage, you’ll have to re-partition your device in Odin with the help of an appropriate PIT (Partition Information Table) file.
Click to expand...
Click to collapse
Re-Partitioning Explained:
NAND memory on Android devices is divided into partitions and block structures. These partitions are essential to the proper functioning of a device. It’s the PIT file that tells Odin how much space to allocate to the boot, kernel, system recovery, data, and EFS partitions. Not just that, it is also responsible for the location and path of these partition blocks on the internal storage.
The Re-partition option in Odin is not meant to be used during a normal firmware flash. If you have to install firmware, just add the BL, AP, CP, and CSC files to Odin and do not change the default settings.
The PIT file determines the structure, location, and size of specific partitions. Since a NAND erase wipes all partitions, the only way to re-partition your device using is to flash a PIT file that is strictly for your Samsung Galaxy device model and storage capacity. Flashing a wrong PIT may result in a semi-bricked device. Moreover, if you flash the PIT file of a 128GB device model on a 256GB model, your phone may be configured to show only 128GB as available storage.

Instructions
Grabbing the right version of Odin is the first step. Due to the fact the tool is never meant to be used by consumers, Samsung doesn't host it on a public download portal. Fortunately, XDA Senior Member realbbb maintains a repository of verified copies of the Odin tool. He also offers patched variants of Odin (known as "3B patched") that are capable of bypassing a number of stop conditions while cross-flashing.
