Accidentally Disabled OEM Unlock on SM-N950N (w/ SM-N950F CSC), how to Recover Data? - Samsung Galaxy Note 8 Questions and Answers

Hey guys,
Here's the situation. I was in the process of completing the setup of my 768GB Note 8 (SM-N950N) with Dr.Ketan P12 custom ROM, and RZ Kernal (for DriveDroid support). Out of nowhere, my Note 8 camera just stopped working, and the Dr.Ketan ROM Tools and Tweaks Pro apps could no longer be opened. I began back-tracking my steps; tried reverting magisk back to v20.1, tried dirty flashing the ROM again, all to no avail. In the process of troubleshooting, figured it could be something I toggled under developer settings. Noticed that my OEM Unlock toggle was turned on, even though I recall seeing it turned off earlier during the configuration process (as explained by @dr.ketan here, scroll to Note for OEM Issue). Thinking it's ineffective, I turned it off and was prompted to reboot my device, just to get stuck at the boot screen
I came across the following forum post describing how to recover from the boot loop, without needing to delete any data, by flashing the latest available official firmware AP***.tar (removed the .md5 extension) file using Odin3:
https://forum.xda-developers.com/sprint-galaxy-s6/help/custom-binary-blocked-frp-lock-how-t3581010
The problem is, during the flashing of the Dr.Ketan P12 custom ROM, I chose to flash the SM-N950F OMC for SM-N950N, in order to use a Korean-Free CSC (more details on why explained here). So, even though I've attempted all of the following:
- flashed the current latest available official firmware AP***.tar file for SM-N950N,
- simultaneously flashed the current latest BL/CP/HOME_CSC***.tar.md5 and AP***.tar firmware files via Odin,
- flashed the latest TWRP***.tar custom recovery (failed probably due to OEM unlock being disabled),
- wiped cache via the stock recovery,
- tried booting via the "Lacking storage booting" option in the stock recover,
- tried booting to safe mode,
- tried using Smart Switch for PC, it (nor its Emergency Software Recovery) never detected my Note while stuck at the Samsung boot logo, nor did it detect it in Recovery mode,
- etc.​it still won't boot-up, and I think it's due to the CSC (UK Unbranded - BTU) not being available in the official firmware.
When I boot into recovery mode, I get the following message:
Code:
#fail to open recovery_cause(No such file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#

E:[libfs_mgr]is_dt_compatible(): firmware info was not valid : '/proc/device-tree/firmware/android/compatible' : No such file or directory
Would any of you folks have suggestions on how I could recover from this mess without needing to delete any data? Perhaps if there was a way I could add the UK Unbranded CSC to the official SM-N950N firmware and flash it via Odin, maybe that'll allow it boot? Please kindly advise, thanks in advance.

No luck on my end, lost months worth of data on my internal storage. Had to perform a factory reset on my Note 8 via Odin, reflash TWRP via Odin, then reflash my Custom ROM and tweaks. Lesson learned for real though

Help me troubleshoot my SDCard errors!

Hello,
Like many other users on this forum, I am having trouble with my i9000M sdcard after doing some ROM flashing.
Although there is some extensive threads collecting the different situations people are experiencing, I was hoping I could get some help for a specific circumstance relating to the sdcard issue.
I'll start by..
- Detailing the firmwares I have flashed, and what happened
- What is working / not working now, and how I got to get to the current situation
- And finally, I'll detail what I'm trying to do and where I'm getting stuck.
I would really appreciate some help with this, and thank anyone who takes the time to read it. I am trying to be very thorough to give you as much information as possible.
-----------------------------------------------------------------------------
1. Started with stock firmware. I am not sure what it was.. I believe the phone is equivalent to the Bell i9000M, but I am on the SaskTel carrier.
2. Flashed firmware I9000XXJP2: This worked, and I was using Froyo 2.2 fine.
3. Tried to root Froyo 2.2 firmware: This FAILED and the trouble began. I was using the update.zip method, and the source claimed it was compatible with 2.2. I had to hard reboot the phone, but it would stall on the white text intro screen (not the animated one).
4. Went into Download mode. Tried to flash firmware I9000UGJH2 (apparently the most current bell firmware), using Odin v1.1. This FAILED, and I had to hard reboot, which resulted in the PHONE - ! - PC error. I am aware the i9000M can still be recovered from this state.
NOTE: I could do nothing at this point: all firmware flashes failed, UNTIL I CHANGED TO ODIN V 1.3!
Using Odin v.1.3:
5. Flashed a series of firmwares.. (I9000UGJG8, I9000XXJM1, I9000XWJG5), ALL resulted in the phone either being in a shutdown-boot loop to the white Glaxaxy text screen, or the battery charging screen.
I could enter Download mode to reflash, but NOT recovery mode.
6. The ONLY semi working firmware is I9000XXJP2, Samsung Froyo 2.2. This is what the phone is now.
- I CAN enter Download mode, Recovery mode, and the phone stalls on the white Galaxy boot screen, but goes no further, and does not restart.
- I CAN run abd commands
Here is the output I get from each of the options in the Recovery mode:
Code:
I9000XXJP2
Odin 1.3
512.pit
Flashes fine
Goes into recovery mode

- power off: battery charging indicator shows
note: it does not loop the battery indicator
- power on: stalls at Galaxy S GT-19000 white lettering screen.
note: i recieve an indication on windows desktop that a device has been connected which is capable of USB high speed point
ADB COMMANDS WORKS: device is detected
Things I have tried:
I tried booting into a Ubuntu Live cd to see if I could format the sdcard, as suggested in this thread: (sorry, forum won't allow me to hyperlink, thread id=759910)
The disk utility picked up the Samsung drives (One was labeled something like Samsung_Galaxy, and the other Samsung_Galaxy sdcard, but I'm not 100%) but could not format them. There was also no info being listed about the size.
Things I would like to try / have hunches on:
Before all this happened, I made a Nandroid backup of the orriginal firmware, and copied it from the i9000's sdcard to my computer. I made the backup using Rom Manager's Clockworkmod.
Is there a way to use Odin to flash Clockworkmod, so I can restore this backup?
-everything out there says to use Rom Manager, which I can't access because the phone is pseudo dead.
Will the backup even still be on my sdcard?
Wait, my sdcard isn't mounted.. can we try mounting it with abd? (I tried, but am not sure of the command / path of how to do this..
Can abd be used to restore my backup stored on my computer? Is this dependent on the sdcard being mounted?
I fully appreaciate those you take the time to read through this as it is rather lengthy. I just want to ensure I have tried every means to revive the device, and hopefully some more skilled users can help with the mounting and adb syntax.
All comments and ideas are welcome and appreciated! Thank-you
Sorry to be the bearer of bad news. But time and time again this error has proven to be a hardware error. Mine did the same thing and samsung/bell had to replace the mainboard in my phone. Good luck, but unfortunately, anything you do further is a waste of time short of sending it back for repair.

Stuck on glowing Samsung logo

Hello!
This post might be a bit lengthy as I try to explain in detail what happened. Sorry for that!
I already read the posts suggested upon entering the title on this one, but I could not find a solution for my problem....
Three days ago, my P1000 (non-rooted, GB via Kies) froze. I turned it off (by pressing Power for a few seconds).
I turned it on again. It booted, but reached only the Samsung logo and would stay there forever.
I turned it off again, removed the external SD and did the factory reset (via Power+VolUp).
It did the reset, but the problem of the glowing logo remains.
I started to google a lot, and got acquainted with Odin, (Stock)ROMs, tar files, PIT files, etc.
but I could only gain a vague idea of all these things as I lack a deeper background knowledge.
So I downloaded several (Stock ) ROMS and PIT Files and tried to flash them on the P1000 using Odin.
The last combination was GB-Stock-Safe-v5.tar together with gt-p1000_mr.pit, recommended as being a good way to "re-stock" the P1000, which I tried to flash with Odin (repartition checked, since having a PIT file). It almost worked but movinand.mst failed. So I removed it from the tar file and tried again.
This time the hidden.rfs failed. So I removed it as well from the tar file. Then the flashing succeeded (but without the movinand.mst and the hidden.rfs)
And the problem remains.
When going into Android recovery mode <3e>, it says:
Finding update package...
Opening update package...
Verifying update package...

csc : deleting /system/csc
csc : done
Successfully installed package.

Successfully applied multi-CSC.
Maybe I have now what is called a "soft-bricked" P1000? My P1000 can only go into recovery mode and into download mode (and into "glowing logo" mode).
I would be grateful for any help so that I can bring the P1000 back to normal life...
Thanks in advance.

I already firgued it out, but tnx for the response.
I bought sd card(didnt have one), did dload method, since normal one approach didnt work i used force update approach(dload moved to sd card, power off, hold vol+ + vol- + power button and it installed) also i needed to flash stock recovery beforehand(so it removes twrp, used fastboot to do it, phone was unlocked, power off connect to PC via usb cable and hold down vol- right away, then flash it through fastboot), it cant do force update with twrp still installed.Once it was done i normally booted to stock rom, phone was no longer unlocked, now i unlocked it flashed twrp and rooted it, everything works just fine.Hope it helps some1 with the same problem.
source: https://forum.xda-developers.com/p10-lite/help/original-service-rom-huawei-p10-lite-t3688097 , there is guide thing for both normal and force update
Thank for the help. It gives me a clue but I am still struggling as the force update approach get stuck at 5%. Thanks anyway.

The binary error you are getting is because you are trying to flash older filmware than what is already on the phone., this is not possible because of security updates. Downloading the latest filmware for you device should resolve this error, and then hopefully fix the other errors you face.

In post number 2 in the thread below, you can install "samfirm" on your Pc, this will give you the latest update to download, at a fast speed. For region (on samfirm) put your service provider, ie BTU or XEU for the UK.

sooooo.... it was working fine for a couple days then the phone froze with a glitched horizontal line on the screen, i rebooted the phone and thought nothing more of it. A day later did the same thing (different place in the screen this time) i have wiped the cache a few time times but it hasnt improved. It is also freezing on the samsung loading screen and or getting stuck in a boot loop, the phone does work normaly for short amounts of time (few hours or so) but keeps happening, i managed to copy this log from the recovery menu if any help
p.s this is simlar to the original problem i was having before i changed the firmware

This is beyond my knowledge. I would take a guess that you have some sort of hardware issue as flashing stock filmware usually resolves any software bug. Hopefully someone who has faced the same or someone more knowledgeable will be able to help you further.

As we have said many of times before, if you lost your EFS folder and you never made a backup of it then you're screwed and you'll need to send it to Samsung for repair because you can't use anyone else's EFS because the EFS holds your IMEI and the phones serial numbers and such. It's information that's never supposed to be removed or deleted.. However someone else said if you delete certain stuff in the EFS folder and then reflash it that it would work and I tried this method and it failed to work so I don't know any other way except sending it to Samsung repair facility.. It also requires root access which you obviously can't do since it's OEM is not unlocked so I really doubt there's anything you can do short of sending it to Samsung..

Failed to mount /system || failed to verify whole file signature || signature verification failed

Hello,
first of all thank you for this forum...
I have an old Samsung J3 2016. The device was very slow so I decided to try to install a custom rom, but I did something I hadn't to do! I even can't explain what's happening.
Some infos:
the device should be in debug mode
OEM unlocked
I have downloaded the original pit file using Heimdall
I flashed something ( I even can't recall what I have done) and now the device doesn't boot properly
I can put it in download mode (volume down + power button + ....)
I can put it in the other condition (?) (volume up + ...)
I have a PC running Linux Mint 20
I can connect the device to my PC through Heimdall but if I try to flash ROM I get errors*
I can connect the device to my PC through "JODIN3 Casual" but if I try to flash something JOdin tells me that my PIT file is corrupted and if I try to ask JOdin to make a custom pit file it tells me to restart the device. The device restarts and JOdin doesn't see it.
Error when I try to flash something or update from external storage: see file attached.
WHAT CAN I DO??
Pardon my bad english and the lack of infos due to my poor knowledge
