You can try to download default samsung firmware from sammobile and use Odin to install the firmware. For me it works.

thanks for your replies mates!!
I do not understand what is the difference of the files that I flash with factory oxa the samsung firmware.
I understand that the firmware in samfirmware there is only one file within a zip to put in pda only and oxa factory has 5 it is mentioned in the first post to leave the factory.
or you mean that first flash of a file and then the oxa factory?
thank you very much:laugh:

[Q] flashed official kitkat and kies wont recognize it

After running into some issues while upgrading to an official kitkat firmware I managed to boot up my phone but now it doesnt get recognized by kies even though its official. I also cant see which csc Im on since when I type in *#1234# it simply goes away from the screen as if its been wiped.
any clues? should i flash something else over?

Try flashing this in the attachments using odin the same wayy you did the stock firmware, just extract the rar file and use the .md5, and then do a full factory reset then it should recognize.

forget KIES ( completely useless) ! flash SamMobile's firmwares with ODIN !

All this files are in one zip. Unzip and put this in appropriate windows in ODIN.
Here are Odin 3.12.3
Good Luck.

Of course, this will wipe my device again, even though I do not select the CSC?

If you allow it to flash a new system and user data image then yes.
You basically need a wipe anyways going from MM to Nougat.

I'm already on Nougat N920AUCU4EQC5. I'm just trying to avoid having to wipe my phone

When i use this. It passes Odin then when the phone tries to reboot and install the update it says deleting then im back to 6.0.1. Any idea why?

I update first post with newest ODIN. Are you unzipping file you download and put tar files in correct windows? Are you in Download mode when using ODIN ?

I'm not sure about security . It was a stock at note 5 until I tried updated to qb2. All dev factors are turned on, and the rar files are all unzipped and loaded through odin in download mode. It passes then the android update screen (the little robot ) says erasing upon revoot and I boot into mm again

OK. Try this , After you unzip from one zip to 4 files , unzip all 4 files to tar.md5 and try ODIN again. Check for any encryption installed on your phone preventing bootloader from overwriting files.

You have to necessarily erase the security lock fingerprints, you also have to remove the password lock, you have not any type of security lock, then you have to enable developer options and type USB debugging(This last one I do not know if it is strictly necessary, but just in case)If you have some security lock on your phone, even if you pray, you will not be able to!

What did you flash before this stock firmware?
DRK=device root key
Clicking from Edge of Galaxy

Just a thought, can you Odin flash any other version of the official AT&T firmware? Maybe try another version to see if the phone is truly screwed.
Also, have you tried a factory reset on the phone first. Maybe something (anything) loaded on the phone is preventing the Odin flash. I know this shouldn't matter but it's worth a try.

Same here.. i try to flash it via odin v3.12 it showing pass message..
After reboot my phone still on MM 6.0.1

Cannot revert to stock, ODIN says pass but resolves nothing

Hello all, I seem to have a problem with my N7100. It does not boot to the OS. It is able to boot to ODIN Mode and CWM, although in CWM it reports that it cannot mount anything. And when I tried to flash the stock firmware using ODIN, it does not change anything even though it says PASS. Heck, even the recovery is still CWM. Any ideas how to solve this?

Did you try flashing a stock ROM with a pit file?

I did, and it gave me the same exact result without a .PIT file.

Sounds to me like the memory chip may be damaged.

Hi,
Will i keep my data on my rooted A520f if i flash HOME_CSC update manually via odin ?

Thanks in advance,

As with any software thing, things can go wrong and thus why @moozer said "should be okay." If he said "yes it will work" and all your porn vids or whatever you have got deleted, there is a chance that a noob could get very mad at someone. After I am done this rant, yes theoretically that should work.

Thanks, so flashing this will not re-encrypt /data?

From what i read here https://forum.xda-developers.com/android/general/how-to-backup-restore-android-device-t3602583 it will
erase internal memory: "Flashing Factory Firmware using flasher will also erase internal memory." ?

Your personal data will remain if you flash "HOME"
CSC – personal data will be erased
CSC_HOME - personal data should be safe
I've done it several times with no issues, however, that is not to say that it is 100% perfect 100% of the time for 100% of users.
BEST ADVICE... ALWAYS BACKUP
ALWAYS

Yes

all worked fine. thanks for heads up!

Yes HOME_CSC keeps all of the original data.

Well, I did it on one phone using home_csc - all data stayed intact, did on another phone - even though Odin reported flashing fine, phone crashed and I had to do factory reset - go figure! In both cases I used the same bin version of the firmware.

CSC!
AP : CODE
CP: MODEM
BL: BOOTLOADER
CSC: CSC or CSC_HOME
USERDATA: USERDATA same for when you need to wipe the user data.
Note: the firmware you are trying to flash should have the same version than your current version on the device or higher, otherwise you may get an error in Odin

Really not sure. Best advice has already been given - to backup if unsure.
If you choose to attempt a downgrade, ensure beforehand that a full TWRP backup is taken in case things don't go the way you planned.
Otherwise, check the forums for downgrading firmware discussions.
Unfortunately I don't have this device any longer, so cannot accurately advise you to say "yes".
Hope that helps. Let us know how you get on.
