Random factory reset and rolling back one UI update - Samsung Galaxy S8 Questions and Answers

So while i had my phone in my pocket while at work as i had done thousands of times before but now all of a sudden i take it out to check a message and the phone reset itself and wiped my internal storage and sd card of all videos pictures and music. so im pissed about that but then the dreaded one ui update rolled around and just made for an even more frustrating night.
So im asking for help for 2 problems; Hopefully restoring all that data from the SD card and rolling back to oreo.
Im new to the forums havent done any kind of firmware messing around so help in much detail would be appreciated thank you.

if it makes any difference its a SM-G950U on Verizon

Restored myself back to oreo but still havent found a way to restore the sd card data. it was a LOT of pictures.

Use a recovery software with the sd card plugged in a computer with Windows

My Storage card seems to be wiped and its gone

This morning my MDA Vario 2 says that my storage card is not installed. It flashed up as empty just before it dissappearred. THere wasn't anything on it that wasn't backed up somewhere but I would like to find out what has happenned and sort it out.
I am going to do a hard reset as I haven't done one for a long time and the device is ready for one anyway and then I need to see what has happenned. Has anyone any ideas?
fixed
It was obviously just objecting to being so 'dirty' as after a full reset its fine again.

[Q] Phone wiped and reset itself (NAND) after charging battery

I am sitting here in a bit of a shock and am not sure what happened. I went to charge my phone which was off due to battery dying, nothing new at all, I just hit the power button, waited for my splash screen to pop up and plugged it in, walked away... I returned to my phone and it was as if it reflashed itself. Android was asking me to set it up again. Everything was reset.
This is a first for me and I admit that I probably had this coming because all my Nand stuff is old. I last updated this phone in February. So yes, I have old MAGDLR, (1.11 I think) my rom is NexusHD2-Gingerbread V2.2 by Tytung IIRC. My radio is 2.12.50.02_2 which I never had an issue with but I understand there is another one recommended. My phone is TMO US, for the record..
I am probably answering my own question by stating how old it all is, but I am just surprised as to why this even happened. I have had some random issues like trying to install things from Market and there is not enough space available so I have had to uninstall stuff. The phone would get laggy and I assumed it was due to apps eating memory which happened a lot. I am not sure if my memory failed in some way or files got corrupted because NOW it claims I have ZERO memory internal. Sounds to me like the partition is messed up. My SD seems in tact yet no apps show up that were on it.
I did some searching for my issue and did not find a lot so I apologise if I am redundant in posting this. I have a lot of catching up to do on what has changed in the past months with Android NAND for the HD2 and I am a bit overwhelmed by the idea as I was not prepared for my phone to reset itself for no apparent reason. Any input is appreciated.
Well, I have run into more issues and its with Windows 7 64bit not liking my HD2 and refusing to install drivers. I have the HD2 toolkit and the driver page is unavailable. I have searched and one of the only answers to this issue I found was reinstalling windows 7 I doubt I need to do all that since I have recently wiped and reinstalled windows 7. Updating my phone should not be this complicated but I suppose this is pertinent to Windows 7 because Vista gave me no issues ever when flashing things. Any idea what drivers I am to install and where to find them?
I update to retract my need for drivers. I found them. I then had boot loops for again an unknown reason and did a restore point all the way back to February from CWMR on a hope it would fix the issue. It seems to have worked. I hope I can update everything in proper order. In what order that is, I do not really know. I want to update the radio but am not sure if that can be done without reverting to Winmo.
I still am hoping for some input on why this whole thing may have happened. If I was not clear on my first post, I apologise. The whole ordeal has me pretty thrown. I think this was an internal memory corruption of some kind. Now that I have recovered my old Nandroid from Feb, it seems that I have 599MB of internal storage. That is better than the 0,00MB I had last night. Just confused why it would do that.

I do not know how to help you with your problems, but if you ever want to switch bootloaders my guide can help you. The radio can be flashed from the tricolored screen.

[HELP] HARDBrick - yep, I'm the first one !

Hey guys
Just got a S5 (previously owned a S2 and S4 Active, which I have rooted and put custom ROMs so many times. Hence I'm familiar with Odin, Recovery, etc etc).
About a week ago, I installed Shohat v5 ROM, everything went fine. I was quite happy with it.
I installed back my app from my S4 Active through a big update.zip (backed up with Titanium paid version) thanks to custom recovery.
And just now, when my battery was like 5% left, I decided to make a hard reboot (as Xprivacy warned me that I needed to restart to have my changes into effect).
I charged my phone and THEN I push the reboot button (not the hot boot).
While charging, the screen went normally black, but stayed black with the blue LED notification ON (not sure if that info is important).
Then, black screen stays forever:
- no logo
- no download mode
- no recovery
- When phone is connected through USB to my laptop, I hear the usual "tadaam" sound from Windows, but no "USB notification".
It seems a JIG would be the solution, but no idea if that would work for a S5 (I guess Samsung has now worked to avoid that solution)
Well, if anyone can help, that would be cool
Obvious I know but you have pulled the battery for a while and tried again right?

Hello
Indeed, I just removed the battery for a few hours a tried, no success.
But is it normal that a hardbrick can occur 1 week after installing a custom ROM?
Right now I can't bring it to Samsung store for repair...
(Adding a new post as editing is not working properly)
Isn't there a way to use ADB with commands through Windows (as there is the "tadaam" sound when I connect it through USB)?
A friend of mine bricked his Nexus tablet and went through such solution to remove the brick ...
OK ............
Here's the magic
After removing on and off the battery many times, trying to boot in recovery or download (trying about 15 times)
Now I managed to boot in recovery (I was like "huh?" and "wooohoooooo")
Did Wipe cache
Did Wipe Dalvick
No Factory reset
Fixed root (seems like I lost it, no idea why)
Let's see if I can reboot it
I think maybe the issue came from the huge update.zip created from my S4 Active (i9295) with Titanium backup (I was in Android version 4.2.2).
Maybe the reinstalled apps, messed up something as the ROM was in version 4.4.2...

OK ... bad news again
I performed a hard reboot to check that everything was stable, and phone rebooted fine.
then I turned off and removed to battery to put back the SD card and the SIM card, and now the phone is not being turned on again.
And now the phone is not able to be turned ON again...
What's going on, any idea?
*** EDIT ***
I managed to reboot in custom recovery totally randomly after playing with the battery (removing, putting it back, trying to boot)
I made a full factory reset and reinstalled the custom ROM Shohat.
After rebooting, it went directly to ODIN as it was displaying error messages "ddi: MMC_read failed"
I guess the internal SD card is dead.
Questions:
1/ Is warranty OK if
- KNOX counter is at 0 (no idea why it is at zero)
- Current Binary is set to OFFICAL
- BUT SYSTEM STATUS is set to "CUSTOM"
2/ Can a custom ROM do this or is it a hardware failure?
Did you try with another sd card did you have apps installed on this sd card for me this sounds like a dead sdcard issue with some apps on it. I had the same issue with my X8 when a lot of apps ware running from the sd card btw sd cards are totally unreliably for storing important data as they usually die after some writing on them.
Change the SD Card and I think your phone will come back to normal.
SD Card Reader

I don't know if this helps but I had an GS-900H (S5 octacore version) and struggled with it for a week trying to debug this problem, ordered new memory cards, installed different ROMs, etc. only to find out that the card reader was bad.
In my case it would corrupt the card every time so that my PC would need to 'repair' it before I could begin using it in the PC.
Maybe the card reader is a common point of failure?
EDIT: I also had issues with different cards working and not working based on the speed of the SD card (different S5). I know for a fact that it will switch you over to main memory when taking pictures that require advanced features -- I got a popup telling me that my memory card wasn't fast enough.

Hello guys
Thanks for your input.
Unfortunately I do not have an external SD card, the issue is with the Internal memory
So i can not request new ones or try to replace it, or work on the card reader...
Amazing that you are about to lose your phone forever and you don't even consider installing the original Samsung firmware.
What da f*** are you doing?
100%. Numb nut doesn't deserve the great phone It's like he got OCD.

Hello
Well, not sure that ODIN will work as the internal MMC is not recognized, so where would that be installed?
Furthermore, I'm waiting for the feedback from Samsung (as knox counter is at 0, Binary is set to OFFICIAL and only status is set to Custom).
I did not want to change these counters with manipulating ODIN.
If Samsung gives it back to me with a new one, then wooohoooo
If Samsung says "f*** off, you manipulated it, warranty is off", then I'll use ODIN with STOCK ROM from Samfirmware + PIT file (they are ready for use on my computer)
If you can't get to download mode how do you propose to use Odin to flash stock ??

[Q] Apps can't write to SD card after using CM and then going back to recovery.

I've been trying to fix this issue for about 4 hours now, so this is my last resort.
A while ago I rooted and installed CM on my phone since my galaxy s4 was bought from dubai so it didn't receive the regular android updates (it's still 4.3). I used CM for a while but realised that my phone was overheating a lot and battery life was a lot worse. So I decided to go back to my recovery.
After going back to my recovery everything worked fine but apps can no longer save to SD card, I can't recieve pictures, download podcasts or use anything that requires SD card.
I'm not very familiar with android coding but I tried using ADB and I just got confused, I also checked permissions in platform.xml and I've tried that solution and it still doesn't work. I've tied unmounting and mounting the sdcard I've tried formatting it in the phone itself and formatting it via recovery. I have no idea what else to do.
It's standard in the later version of Android. So it has nothing to do with CM or custom roms.
Google for "i9505 write sd kitkat' and you find plenty of guides how to solve it.
Why didn't you just download the latest version of CM and use that?

Encryption Issue

My phone is hung up on the "Encrypting SD Card" process. Selecting encrypt or decrypt in the settings does nothing and the SD card is currently unmounted because of it.
This has happened once before but went back to normal after I applied the update that came out last month. Just ended up being great timing. Any ideas on what I can do get the card to remount? I don't want to reformat the card because I know this is fixable but I need to know how to clear the cache or reset the encryption task, or whatever the update did that let it get back to normal. Once this is fixed, the card will be decrypted and it will stay that way. The encryption process does not seem to be all that stable at this point.
Thanks in advance!
