Got my KNOX counter reset to 0 - Galaxy S6 Q&A, Help & Troubleshooting

In case this is useful for further investigation on this matter, long story short:
1. Bootloader unlocked using CROM Service.
2. TWRP installed.
3. Several custom ROMs/Kernel installed, phone rooted, etc.
4. While on a custom ROM/Kernel, attempted to encrypt the phone, encryption fails, TWRP bootloops, several attempts to fix it, not even TWRP boots now. Great.
*Background: Previous days fast charging and file transfer failed a couple times, didn't give it much importance, assumed was a cable issue.
5. Clean install attempt via Odin mode, computer doesn't even detect the device: device malfunctioned/unknown device.
6. Changed official cable #1 to official cable #2. Same issue. ADB doesn't work, OTG doesn't work, fast charging doesn't work, nothing.
7. Brought phone to service, they attempt to connect it to their computer and fail. First diagnose: USB port is broken, they need to fix this before attempting to fix the phone.
8. They boot Odin mode in front of me and eyeroll: you rooted eh? you have no guarantee.
9. -OK, but can you fix it? -Yes but we need to change the USB port and you need to pay for that.
*I read somewhere that Odin is very sensitive to cable quality and there are some reports of people having failed connection due to dust. OK, it may be the port after all, at least to attempt Odin connection.
10. Went back the next day, USB port has been changed and phone is back to factory state. Surprise for me when I boot in Odin mode and find out that KNOX counter is 0, CROM is locked, etc.
11. USB port replacement cost: 50 bucks.
I am by no means an expert and I've only read a few posts about KNOX before rooting my S6. If I had to speculate, based on my experience, I would say that if it is an e-fuse it can definitely be reverted and, it's a physical fuse, then it must be in the USB port.
Now back to tripping KNOX again... but this time without encryption.
Hope this helps.

I would at least wait a few days to see if everything works ;p

where is CROM Service??

From what I read about older exnyos phones, the e-fuse is not physical but then again, this is a new phone, new processor.

Probably they gave you a new motherboard.

for $50!? no way

New M board definitely .

The repair shop can return the old MB to Samsung on warranty and pocket your $50.. They can also break it more so that the tripped KNOX doesn't show up any more

New motherboard for sure... No miracles included!

If this is a new motherboard then serial number/imei would be different from what you have on the original box.

Disagree.
Sn and Imei is replicated from old one.
The same as laptop warranty services do.

Just checked, IMEI and S/N have changed.

Encryption won't work with a tripped Knox flag?

[Q] Bricked(?) European Galaxy Tab P1000 16Gb

Hi every body,
To start with, in order to avoid asking stupid questions, I've been trying to fix the problem and searching posts for about a month now (ironically, this might have been my mistake, trying everything possible
The answer to the question "why the heck did you do such a stupid thing?!" can be found at the end of the post, for those who has the time for others who are willing to help, and I'd be thankful for any, here are the details:
Device:
European Galaxy Tab P1000 16Gb 3G
Serial Number: you wish! )
Device is rooted and HAD the latest official update provided with Kies
Current state:
- Device stuck at the Samsung Galaxy Tab screen
- No recovery mode (volume-up + power on)
- Download mode still works (volume-down + power on
How did it happen:
It all started as I replaced the framework.jar and a couple of other libraries using adb (why the $$$$ No. 1). this would have been no problem, if I have left usb-debugging switched on after that, but I switched the usb-debugging off(why the $$$$ No. 2). After that I couldn't restore them using adb, logically...
I tried flashing several frameworks with no success. at the beginning, my mistake was using wrong combination of pit-files and roms.
The cause of all evel:
at a certain point I decided flashing with the clear efs option selected (why the $$$$ No. 3). Now I know I shouldn't have done that. especially that I have no backup of the original efs.
What does NOT work
Flashing with Odin or Heimdall theoretically works (I get no errors, the process finishes successfully and the device restarts). Still, it's stuck at the same Samsung Galaxy Tab screen, and still no recovery mode (volume-up + power also shows the same screen).
I tried flashing different samfirmwares and Rotos (using the propper pit-files and stricktly following instructions) to no avail.
I also tried flashing both with the sim and sd-card in the device, and after removing them.
so please HEEEEEEEEEEEEEELP!
why the $$$$ did I have to do this :
1. replacing firmware.jar: I wanted to add native arabic language support and I found this post on the internet providing instructions and jars - of course, it was a mistake to do it, but it's too late for that now, isn't it
2. switching the usb-debugging off: I wanted to copy files to the external card. I have no idea what I was thinking! first of all, I should have first tested whether the stupidity in point 1 have worked, second of all I can still access the sd-card with the debugging switched on! but I didn't know that at the time.
3. clearing the efs: Now, you didn't expect a logical explanation here, did you? ) I was frustrated and said what the heck! Ok ok, have your laugh, call me stupid and all you want - I deseved it
So, once again, any help would be just great!
Thanks in advance,
Moh
If your EFS is gone then you'll need to take the device to Samsung for repair. Samsung may be able to regenerate the EFS data based on the hardware, or they'll have to replace the mainboard.

How to brick Galaxy S6

Out of curiosity, is there way to brick this device to stage that for example warranty service can`t find out that it is self-inflicted?
Surely, flashing a bootloader not intended for the device is the best way to brick it?
i will do in that way :
flash engeniereng bootloader
flash a rom not suitable for your device ( ex. rom for 9200hk )
if still works, flash wrong pit file or modified wrong one )
Why would someone do that anyway???

I can tell you why someone would do that. This is purely hypotethical but here is one reason. Let´s say that you have rooted your device and lost your warranty. After that your camera starts to make buzzing noise and focusing don´t work. ie. this case: http://forum.xda-developers.com/galaxy-s6/help/galaxy-s6-camera-randomly-makes-loud-t3123724
Now you want to get that camera fixed for warranty, but they don´t accept it because Knox is tripped. But now if whole phone is bricked and be sent to warranty service, they have no other choice but flash stock firmware and untrip Knox and device will gain full warranty again. Or that is my theory anyway. I mean sometimes these devices just stop working maybe due faulty motherboard or something similar. Please remember this is totally hypotethical...

Dark ideas! I like it!
I bricked my G920F trying to get back to stock-rom. Nothing would work, Odin failed time after time (cm.bin). I could flash TWRP and used ADB to get back to stock-recovery, connected to smart-switch and performed emergency restore. Failed again.
I took it to a Samsung servicepoint (talking about Holland) and they immediatly found the custom flag. Phone wil be send over to Samsung now and, according to the lady at the servicepoint, Samsung does not even check. They just reflash it and send it back under full waranty. All I can do now is hoping she is right....
Still figuring out why everybody but me can restore a bricked phone through ODIN.

Hard bricked

I just hard bricked my phone, and I'm hoping I can try to get it working again.
I have made backups using flashfire in the past. (I had a few different backups I made).
Prior to getting hard bricked, I was running the PIA firmware, but I was trying to restore from a backup that I had through flash fire, and due to a total rookie move I ended up restoring (or attempting to) restore to a PG1 unintentionally, and well now I can't do anything.
I think I may have a jig at home from a previous samsung phone (I believe an S3), would that work for my S7?
I also came across this thread: http://forum.xda-developers.com/showthread.php?t=2476353
Would that work for me?
I have a macbook pro I can use terminal with, I have a microSD card and reader, and I already have the stock PIA rom on my hard drive.
Is there hope still?
Right now regardless of what key combination I hold down my phone has a black screen.
Any help would greatly be appreciated.
Thanks in advance!
If you can't get into download mode then you don't have much to lose by trying what the other thread suggested.
@sacnotsack, thanks for the response, and that is my intention, however I am missing 1 crucial part to that thread and that is the debrick.img
Can someone with the PIA (G930TUVU4APIA) rom please post a dump of a partial system img for me? If I'm not mistaken, you can dump it with these commands in ADB.
adb shell
dd if=/dev/block/sda20 of=/sdcard/debrick.img bs=4096 count=128
Just to clarify...
sda20 should be the system partition. Any way that's what it is for me.
You can check yourself by doing typing this in ADB:
ls -al /dev/block/bootdevice/by-name
You will get something like this:
lrwxrwxrwx root root 2016-01-08 10:35 system -> /dev/block/sda20
And to get the block size you would type this:
blockdev --getbsz /dev/block/sda20
So the command
"dd if=/dev/block/sda20 of=/sdcard/debrick.img bs=4096 count=128"
If I get this working, I'll compile a nice tut for S7 users and post all the results with files in case anyone else runs into this issue.
Thank you in advance
I don't mean to be an annoyance, but does anyone have any thoughts or could point me to some direction? I know there are a lot of you that are much more knowledgable in this than I am, and all I'm hoping I can get assistance for is if someone can just make a dump of the debrick.img file so I can try to load it on my SD card.
Thanks
Hi, the easiest way to restore back to stock is to download Odin. I think it's Windows exclusive so you'll need bootcamp and install windows. After that, download Odin and extract it. Download stock firmware from androidfilehost.com, then extract. Open Odin and you'll see the options BL, AP, CP, and CSC. The firmware will have 4 or 5 files and will include these labels. Put each respective files into each options in odin. (Sometimes Odin will freeze, but let it do it's thing) After that, go into download mode (hold Volume down, Power, and Home whole turning on). Wait for Odin to recognize your device, if it doesn't, then download Samsung drivers. After it recognizes, press start and wait for the process to finish. That's it! Hopefully I was able to help.

MetalPhoenix45, thanks for your response. I have a Windows computer as well and I am very familiar with ODIN. The issue is, that in your explanation my guess is you are thinking the phone is in a "soft bricked" mode. The difference between a hard brick phone and a soft brick phone is that in a hard brick phone nothing is recognized when plugged in, it doesn't power on and it also doesn't show any sign of charge when it's plugged into the power.
In a soft brick mode, your phone can be stuck in a boot loop, or at the very least it still shows signs of it getting power. In which case I can just force into download mode and do what you stated above. I don't think that the things you mentioned above would work for me because when I have my phone plugged in to my computer, in device manager it doesn't detect anything. It doesn't even say unknown device or unrecognized hardware. It doesn't see it at all, and I have loaded the Samsung drivers on my pc because ODIN recognized the device prior to my issue.
I do have the stock firmware and everything on my machine, but I just can't get my phone to power or on into download boot even with a JIG.

Have you had any luck on fixing s7 I've got same issue I've even got device broken down minus the charger port due to cost of screen replacement! Not sure exactly how to test battery itself but every combination of testing battery externally I've nothing any ideas? I'd rather replace the battery vs charger port or is it completely done? This is.the first root I've ever had go wrong and haven't found any solutions yet and been looking since November
Thanks in advance for any advice
On rooted 910v now have a 920t rooted but let's just say my temper got the best of me and we'll will be replacing screen? Oddly enough as many times as the note 4 has been dropped either by myself or son not even a single scratch s7 definitely a pot more brittle!!

Unfortunately, I had no luck. I ended up haing to replace the PCB to fix the issue. Basically I learned the hard way that samsung isn't very "dev friendly". I don't blame them, but for any phone enthusiasts that plan on tinkering with their phone if you get the snapdragon version of the S7 vs the exynos version, you WILL run into trouble.
This is because the bootloader can't be unlocked on the SD models. Furthermore, if you get flagged for custom roms your warranty gets void. Over the years I've noticed Samsung is getting more and more strict about this. Honestly if you want a phone that will play nice with modding it, you should look into the google variants, Nexus, or the OnePlus. I can tell you from personal experience, OnePlus plays well with dev users. In fact they don't void the warranty for using custom roms or anything like that; in fact they're very pro and open about supporting the user base and providing a phone that the user is happy with.
Any way, that was my experience. I don't want to go off topic here, so if you have any questions you can PM me if you like, but the short answer is, if you're hard bricked then you will need to replace the motherboard/pcb. I even contacted places to see if they can jtag or jig or anything and they're not able to do it with the snapdragon S7.
bah double post, sorry I can't delete this
Funny you said nexus just ordered 2 two days ago older 7 but 4g and and what not strictly for experimental and ethical purposes of course was actually shocked at the still high priced note 5 Screen tbh but we live and learn!! SOMETIMES? LOL

I am in the same boat, and considering your experience after this sore event, maybe you can help a lot of us guys here in the same situation.
My case is even worst, because, here in my country, there are NO Snapdragons, just G930F Equinoxes.
You may help im providing us lames the debrick.img file, but you must be rooted to do so. This would ve much appreciated.
Another way is to insert a blank 16GB+ SD card on the phone and format it through Odin. You just insert the card on the slot, enter download mode in the phone and load all files in Odin including the .pit. In Odin options select "Re-format" and "T Flash" that will say to the phone to format the ExtSDCard and use the ExtSDCard as destination instead of the internal emmc!
Post the image of the SD, that you can extract it with the Win32DiskImage, and you and your family will be blessed for ten generations. Also save the file in case you mess things again.
There is one method using QFil,but i'm stil trying to asemble all required files and don't now if it will even work. Should work...!!!
Anyway, can you please help us?
Best regards..

Unfortunately, I won't be of much help. If you have the exynos S7, you would need to ask someone else with the same version of your phone for the software because the SD versions would run on different software due to different hardware.
Is there a reason why you don't try sending it out to get serviced so they can replace your PCB ?
I tried to get the debrick.img file a while back as well, but had no luck in doing so and actually I don't have my S7 phone anymore. I bought the OnePlus 3T and it's been working much better for my needs. I'm sorry to say this, but If you have any intention of modding a phone you have 2 options. 1. Get a phone that supports modding and allows you to unlock the bootloader 2. Get the unlocked variant of the phone.
If I have learned anything from my experience, it's that it is incredibly important to do your research. Not only look at the specs of the phone, but look at reviews from other users with the phone. Also if you plan on modding it, go through some threads and see how easy/difficult it is to mod that version of phone you're interested in.

Then i think got stuck, beacause in these forums there is no one willing/able/interested in helping anyone.
I said i'm in the SAME boat == I got an SM-G930T (from T-Mobile) that has a SnapDragon cpu but HERE in my country THERE ARE NO Snapdragons only Equinoxes. If we had such phones here surely i would have done this already, but G930F's won't do, as i have already tried.
So, as you know how i feel about a brand new SM-G930T Bricked, you wold be my last hope. There is no way to send it back to Samsung beacause it was bought from a friend and surely no warranty.
Anyway, best regards and rest in peace
Oh sorry, I misunderstood you. I'd like to think that it's not so much people don't want to try to help out, it's just that there is nothing that can be done for users on the snapdragon device so no one bothers unfortunately. Sorry to hear about this, and it really is unfortunate that you had to go through the same thing I went through with no help. Trust me, if I was able to do anything to provide any guidance I would.
Good luck!

Stock UK S7 Bootloop (Unrooted) Need help!!!

I've looked through the forums to identify a similar problem to mine in hopes I can resolve this issue but I've not found one. So here's my problem.
I have a UK Galaxy S7 running on the 6.0 firmware that came with the phone when it first released (Yes I know it's very old and should have updated along the way but I had plans to root and install customs at some point which obviously didn't happen). The phone is unrooted and the stock rom is the XEU version with Multi-CSC (according to recovery)
The phone was running fine until a few days ago when all of a sudden it shut off and wouldn't power on via the power button. So I pressed and held Home + Volume Down + Power. The green screen appeared and selected Volume Down to restart the device (as you do in odd situations like this).
PHONE IS NOW STUCK IN BOOTLOOP!!!
I have tried various means (not including flashing) to get the phone to boot to the home screen with no success. I have not performed a factory reset from recovery because I have various data, including pictures, music and other software on the internal storage which I wish to keep and not lose. The phone is still under warranty so I can take it to a Samsung repair outlet to get them to fix it for me but due to data privacy or whatever, they have to format it clean to then install the most recent firmware.
I've been scouring the forums for help on flashing OTA updates which retain data on phone whilst possibly allowing my phone to boot into the home screen so I can access my data. Is such a thing possible?
Any help would be greatly appreciated.
You can flash the latest firmware without losing data (as long as the hardware is not faulty) by downloading it from either sammobile, updato.com or using the samfirm tool here on XDA (Fastest option)
Then extract the firmware and add all 4 parts to ODIN 3.12.7 (Do not use ODIN 3.13.1 unless you want to flash BTU Oreo 8.0)
AP << (Takes quite a long time to add, be patient as ODIN will look frozen)
BL
CP
HOME_CSC
If you use CSC instead of HOME_CSC it will wipe the device after the flash, HOME_CSC will not wipe it
Put the phone into download mode (Home & Power & Volume Down)
Connect to PC USB and hit start on ODIN
Wait for the flash to complete (It can take quite a while) and the phone should hopefully boot back into Android
Thank you for the quick response.
It's imperative I get this right and ensure I've understood your reply correctly.
I have downloaded the following:
SM-G930F_1_20180417125627_cz5yqc22v0_fac - from SamFirm as it was much quicker like you said.
Odin3+v3.12.7 - This particular version was quite difficult to get a hold of. Various sites redirecting me to various pages without a direct link to download but I hope that is the correct one.
The firmware zip contains the following files:

I will also follow your instruction of flashing HOME_CSC_XEU_G930FXEU2DRB5_CL13061583_QB16917099_REV00_user_low_ship.tar as this will NOT wipe any existing data on the phone?
Will following the above steps act as an upgrade to the phone and not wipe apps/pictures etc in the internal storage?
Have I missed out any other steps?

Thank you for the quick response.
It's imperative I get this right and ensure I've understood your reply correctly.
I have downloaded the following:
SM-G930F_1_20180417125627_cz5yqc22v0_fac - from SamFirm as it was much quicker like you said.
Odin3+v3.12.7 - This particular version was quite difficult to get a hold of. Various sites redirecting me to various pages without a direct link to download but I hope that is the correct one.
The firmware zip contains the following files:

Almost, you must flash all 4 files at the same time, load them all into ODIN before hitting start, doesn't matter which order you load them in as long as they are all loaded before flashing
And you are correct with the rest, HOME_CSC will not wipe anything, and yes it will act as an upgrade although it is a full ROM you are flashing, to you the user, it will appear exactly the same as an upgrade as long as you use HOME_CSC
No other steps needed
I have loaded all 4 files as seen in the screenshot however, after clicking on Start, about 5 or so minutes later, it says FAIL in the first box above where it initially said RECOVERY. It's stopped and not done anything else.
I'm not sure what to do here.
I've also added a shot of the top left of odin screen

Yea it's failed, you can close ODIN and disconnect now
You can try doing it again, but that should have worked, you could try downloading the latest 6.0.1 ROM and flashing that the same way first, it looks like your bootloader is version 1 where this ROM is version 2 as shown by the S2 number in the middle of the firmware version

I've gone to https://updato.com/firmware-archive-select-model?record=0DB04AD4C34211E69215FA163EE8F90B
From there I've selected the most recent 6.0.1 ROM which is dated 4th December 2016. Problem is that the download is EXTREMELY slow and I have no idea how to use SamFirm to download that particular ROM.
I guess all I can do now is play the waiting game and repeat the steps with the 6.0.1 ROM once it's downloaded.
Thank you for your responses and I will post back here once the download has finished.

Yea unfortunately all alternatives other than samfirm tool are slow, and samfirm only downloads the latest ROM
Judging by the bootloader version and the ROM version you have chosen, if this also fails, then I would assume a hardware failure
The only other thing I could suggest if this doesn't work, is to pick an older version of ODIN to flash the older firmware, ODIN 3.11.1 was used for MM 6.0.1 ROMs if I'm remembering correctly
https://forum.xda-developers.com/showthread.php?t=2711451
or
https://odindownloader.com/download/odin3-v3-11-1
I've restarted the device and it said An error has occurred while updating the device software use the emergency recovery function.
I attempted to reboot the phone a couple of times to get into recovery and I was successful. I now see the the Bootloader version is now 2 as opposed to 1. After seeing this I attempted to flash version 7 as initially suggested yet it did not work.
I'm not sure how Bootloader changed from 1 to 2 and is still failing to flash in odin. I am still waiting for the 6.0.1 ROM to download, fluctuating between 16-19 hours as of writing this response. Once it's ready I'll try and load up odin 3.11.1 as a second solution and try 6.0.1, even though Bootloader says 2.

Your ODIN screenshot looks like it managed to flash the bootloader before it failed, so it's possible you are going to need to use a version 2 ROM from now on, I have the same phone, XEU G930F and it is running Bootloader version 2 (Running the BTU Oreo 8.0 stock ROM)
But if the 7.0 Nougat ROM failed again it's looking more like a hardware issue, seems to be failing when it should be starting to flash SYSTEM (AP)
You can try flashing the 7.0 ROM section AP on it's own with ODIN 3.12.7, see if that fails immediately, if it does that's likely where the problem lies, it's not unheard of for these S7's to fail like this out of the blue, I see it maybe a couple of times a month on XDA
Only solution is to get the mainboard replaced
But yea, give 6.0.1 a shot anyway, worth a try saying as everything else has failed up to now
(Looking for mirrors for that 6.0.1 ROM, I've got it on my main machine but it is offline right now with no graphics card so I can't access any files, stuck with a laptop, I always download and save every new firmware release for this reason)
There is Samsung SmartSwitch software for Windows for the emergency firmware recovery, but it WILL wipe your phone back to factory and delete all your data (Last resort if nothing else works, although if ODIN doesn't work, I'd say hardware failure)
Right so I've managed to download the most up to date 6.0.1 ROM and attempted to flash it with ODIN V3.11.1 and it idles at the recovery.img part and fails like the previous efforts.
I'm not sure if attempting to get OREO running with the latest ODIN might work? If not then I may have to give up and do a factory reset through Samsung SmartSwitch.
It probably is a hardware failure as I had noticed the lightning bolt appearing when the phone is off whilst plugged in the charge, it take about a minute or so for the percentage bar to appear, usually it was about 2 seconds before this disaster occurred.

Worth a try flashing Oreo, BTU on samfirm tool will give you it for the G930F
If you're seeing problems with the charging now, you might get lucky and find the USB port is the only thing needing replacing, but if you send it off for repair it's unlikely even if that is the case that they won't just charge you for a new mainboard, you can likely get USB ports from eBay but opening the S7 isn't as straight forward as the back is glued on for IP68 water resistance and needs a heatgun to remove, not sure if anything else like the screen needs removing for USB, I've not opened mine
You've tried a new USB cable and a different PC too ?

The charging issue occurred immediately when the phone shut off by itself and wouldn't power on conventionally. The phone is still under warranty so if the Samsung SmartSwitch software is unable to recover the phone then I will take it to the repair center and have them fix/replace it. If it's a case of undoing the glue and whatnot then I'd rather they give me a replacement.
I did change the USB cable to a different one, and I've attempted to flash the 2 different ODINS with the 2 different ROMS on a laptop as opposed to the desktop I was using. Still fails at the recovery.img part of ODIN.
I'm going to try Samsung SmartSwitch now and see if this will give it some life. If THAT doesn't work then it's 100% hardware issue and my data was lost to begin with.
Considering both versions of ODIN didn't work with either ROM, I don't think I'll be looking for the BTU version of OREO to attempt to install with. If there's a direct download that's quick I might but I think I'll attempt to Emergency Recover through the Samsung tool.
I want to thank you plenty for your help and knowledge on this. It certainly has been helpful and given me better understanding of the problem I'm facing and potential solutions. I have a feeling that the SmartSwitch recovery won't work either and still be posting back here hahaha.
OK I've got bigger problems on my hands now.
SmartSwitch and Kies both say "SM-G930F" does not support initializing. Please contact our service center.
I've already inputted my serial number and it gives me the same message on both programs. When I called up customer support they said my warranty is till the end of May this year.
Would the service center be able to solve this problem?

Yea I'd get it repaired under warranty asap then if it runs out soon, they will most likely replace the mainboard I'd say, which means 100% data loss as the storage is on a chip on that board, or might even send you a new S7
Really does sound like hardware failure if all of these recovery options have failed, just keep quiet about what you've done to try and fix it, just act dumb and say it won't turn on or they could claim you nulled your warranty messing with ODIN
And no probs, that's what XDA is all about Let us know how the repair goes and buy a MicroSD card to save your important files to this time so you don't lose anything if it happens again

I had an SD card inside with all my pictures I took whilst in Japan (Thank GOD!). I took it out when this issue arose to avoid potential data loss there.
As far as ODIN is concerned, warranty still appears intact but yes I'll keep hush hush when I'm there. I believe they said they'd give me a refurbished S7 if they couldn't reflash it there.

Yes, ODIN will not void warranty if you only flash stock, but telling them you used ODIN might, it's not a tool meant for us, it's Samsung's internal flashing tool not meant to be leaked online, sometimes they'll use any reason to blame you and not have to pay out / replace it so yea best not say anything other than official recovery methods suggested by Samsung themselves, if anything at all, I'd just say I didn't do anything, an OTA update came through and it never rebooted or something
Good job with the pics, I don't save any media to the phone itself, I create folders on the SDCard and move it over if I can't have it save there automatically, that way wiping the phone is nothing but a pain to set back up again, nothing actually lost

I'm going to give flashing one last try.
I am currently downloading Android 8.0.0 for United Kingdom (BTU, NOT XEU). I have to head to work in a few minutes. When I get back I'll attempt to flash that without BootLoader as that will change it to version 3 and you can't downgrade from that from what I've read here and there. If that fails then it's off to the repair center. If it's some sort of hardware failure then it won't flash regardless what stock rom/ODIN version I'm using.
Not sure if BTU update with home CSC will retain my data (assuming it works)

Your CSC will remain XEU as it is Multi-CSC containing BTU, and BTU contains XEU, I'm running it now with BTU firmware & XEU CSC
Bootloader for this Oreo 8.0 BTU firmware is still 2, with it being a new Android version you'll need to flash the BL too anyway

I've had no luck flashing it with Oreo. It's definitely going to the repair centre. Such a shame.
I'm very grateful for your time and help with this. I will report back this weekend with the results of what the repair centre will do regarding the device. Don't like to leave a thread without an end result.
Many thanks again!

Samsung galaxy A31 (SM-A315G) broken screen and touch. DATA backup possible?

As the title says no input or output possible on the phone only through cable in download mode or recovery but bootloader is locked and recovery is factory so not possible to execute commands to do data backup and also developer mode is not enabled. Only thing I see maybe possible is to flash the boot.img with devepolper mode and usb debuging enabled through Odin but not sure how to make the corrections in boot.img if even possible. I think that the android version is 11.

If your bootloader is locked, you will not be able to flash a modified boot.img via Odin, it won't accept it.
If you did not have USB debugging enabled before this happened and if you don't have root or custom recovery, you will not be able to do anything to recover your data unless you find a professional shop that has the tools and ability to disassemble your device and pull your data directly from the hardware chip itself. Or you can get the screen replaced, if the screen is a verified exact match for your specific model number. Don't get a generic replacement screen that claims to be compatible, sometimes these require modifying your software to get them to work correctly, you do not want this.

Id like to learn how to do the data extraction from hardware. I already looked around a bit and if I understand correctly it should be something like a JTAG box ? Can you give me some direction where to start?

I wouldn't know where to start. If I knew, I would have explained it instead of telling you to find a shop that can do it. If the data is important to you, I wouldn't risk trying to learn because you'll more than likely danage the device or destroy your data before you figure it out.
