No i think its stock......actually my friend is using this note 4. Attached is screen of downloading mode which can help you to understand. Actually i am new to samsung.
[Galaxy Note 4 Android Development (Snapdragon)] Cid6.7:
Ok so say I have a sd card thats a class 4 to my understanding you need a class 10..

How do you know if the card actually works or not. Is it simply it works or it does not..?

I froze my phn over night did the steps & nothing happened with a Lexar 8gb class 4..

I guess my next step is going out & getting a class 10..

What does the phone get from the card to boot to begin with..?

Just got a class 10 32gb SDHC...... still nothing is recognized by pc.....grrrrrr.

Use the recovery firmware that is given in the op.

Download the n910g recovery firmware and flash it via odin.

It consists of ap, bl, cp, csc and pit files.

Load all of them in their respective slots of odin, then select repartition, f.reset time and uncheck auto reboot.

Thats it, flash.
[Galaxy Note 4 Android Development (Snapdragon)] G@vi:
Tryed recovery firmware odin giving error of repatition failed. Note 4 screen attached its mmc read fail. Is it becoz we trying to downgrade to 5.0 ?
[Galaxy Note 4 Android Development (Snapdragon)] alquistador:
Freeze your phone first
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
Its definitely not a 'downgrade' problem.

You can even flash kitkat firmware, even though your previous firmware was 6.0.1.

Try to freeze the phone.

Load it in a bag and put it in the freezer.
[Galaxy Note 4 Android Development (Snapdragon)] G@vi:
Its going to download mode after freezing for 10 Min. How much time we have to freez it.
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
There isnt any specific time limit, but almost everyone had kept it for a whole night.

Keep it for one hour and then try flashing.

The question is , we should er frezzer the Phone with battery or we should remove the battery. Another question if we freezer the Phone with battery is nothing happen for battery or battery will not damage.

Just an update: After a bit of a fight, I got my phone repaired under warranty from Samsung. :)

They weren't able to recover it either, so in my case it was EMMC/board failure. Although as I said in my posts it did vibrate with the debrick image inserted but nothing happened further.

Just want to say thanks to the OP and everyone involved for all their time and effort!

Guys , I have my phone working for 24 hours now after i use the freezer process ( twice) .

As I have already told you, only the phone in a zip bag in the freezer, the first time i left it 6 hours the second 7 hours.

Its not only the time to freeze it , its also the time that have to pass until you are able to use oddin again. If you try oddin in less than 4 hours between flashing , it always fails. I have tried more than 10 times until I could finally succeed.

After first success flash with odin , phone reboots and after a while is looking for updates as the recovery files are not the one in the last stock rom.

My phone did twice updates (330 Mb each) , one after other , until, was in the last version which is available for our phone Android 6.01

I think here, that also after recover, make sure that you have a decent wifi connection established, as phone is trying to come back and in the some time is looking for updates, so its very intensive process.

So keep it on charger, make sure you have a wifi available.

After I had finished all that I have installed an APP from PLAY called Wake Lock - CPU Awake

https://play.google.com/store/apps/details?id=com.dambara.wakelocker

which I have set to keep my CPU always on and don't let the phone to go to deep sleep, twice I left it and couldn't make it come back. So set cpu awake for 24 hrs (thats the maximum the app can set).

Also I have uninstall all power saving apps like Greenify etc.

Power saving app usually put phone to deep sleep after screen is off for some time and thats not something we want at this moment, until sometime pass and be sure that everything is back to normal.

Dont worry about battery consumption , over night it had 1.5 % per hour so it in the normal discharging range

Thats what i have done so far, will be updating for new thought and findings
[Galaxy Note 4 Android Development (Snapdragon)] Phrodini:
Were you able to keep your existing files?
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
first time when I was able to finally boot in my phone all files where there.

Apps, media, music, everything. But apparently the fix was not good because after a while, some hours I think, phone was freezing again, stacking when opening apps etc. In that fix phone didnt do any updates , I think because everything was there. But as it seemed that was not ok.

The second time phone made more than 10 minutes to write all file with odin and when rebooted i got messages about deleting files, formating and uplying update. Also recoverying files were in german. I think that the recovery given in op is made from a german phone.

That time , that everything went well ( so far, i dont know after some days what i will see)

nothing was there in the phone, apps, music, all my files was removed and installed as new phone.

I still have the ext sdcard in my phone and havent rebooted my phone since, except the 2 times phone rebooted by its self to aply system updates.

I am too scared to try it for now.

Hi guys. I just wanted to get clarity on this debrick process since there is a wide variety of answers I've read every post.

-----

For my W8, *DO I* have to freeze/debrick with SD card and go in to download mode ***BEFORE*** I can use Odin with the recovery?

If so, that sucks. I've tried the freezing method 3 times (overnight -- ziplock) and 2 different class 10 32GB cards with the W8 image and no vibration. Argh.

Will this work if the phone won't turn on? Not seeing how it can read from the sd card if the phone won't even turn on
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
Snapdragon variants are designed in such a manner that ,even though there is no software installed , the motherboard can be detected in computer (control panel/device manager/port )

It is shown as qhsusb_bulk .

If this is the case , then your device can read from sd card .

It will just open up the download mode, then you can flash the recovery firmware.

Hi bro, I appreciate your help, but this also didn't work for me.

I download the two images from this thread. then I flashed each one using win32diskimager, and a 8Gigs SD card. but it didn't work. :(

---------- Post added at 09:31 PM ---------- Previous post was at 09:23 PM ----------

Hi Bro, I've been searching desperately for a solution for more than two weeks, I read many threads, and I visited many repair stores but they didn't find a solution.

I hope that this solution works, and since you have an N910F you can make a debrick image for me and all the other guys who have the same problem. I would be grateful if you take the time to make it.

yashthemw can show you how, and it will not affect your phone since you'll be flashing the files to an SD card and then making an image of that SD Card.
[Galaxy Note 4 Android Development (Snapdragon)] Trex888:
Did you write debrick.img to microsd card ? If you did then put microsd card in phone and press power button for 5 to 10 seconds then release button and wait 3 to 5 minutes dont touch anything.the phone will boot normally if debrick.img matches your last bootloader. if it didn't match then it will take you to tflash download mode here you can flash stock firmware via odin by using tflash in odin options.

Hey guys i need a debrick.img for the n910f. help me please
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
As mentioned by [MENTION=7617599]Trex888[/MENTION] , do it properly , have patience, it might just work , wait for 5 min after pressing the power button .

You have been waiting for so long for this debrick.img, now that it is there, atleast have paitence , do it correctly.

If your phone is bricked , that means there is no software on the motherboard , except for some qualcomm drivers , therefore it might take some time for the drivers to read the debrick.img.

Not working. NOT BOOTING FROM SDCARD.
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
So the conclusion is that, this debrick.img is not working for n910f .

So , now people with a bricked n910f can ask other n910f users to create a debrick.img with the debrick creator.

All the best .

If there is anything else that I can do tell me. If there is anything to be flashed , just let me know .

But keep in mind , I have n901G variant .

See my friend ,

As per the method , the debrick creator has to be flashed in the recovery, to create a debrick.img.

I did that, now just because I dont have a bricked note 4 , i cant test it .

Anyways , try the new debrick.img .

And report.

Where is the Debrick.img for N910F?
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
two ways that can happen.

1st method: take it out of freezer, put card, put battery connect to pc, push volume down+power+home until vibrate and shows download mode. Then volume up , check in oddin if it says added, start process with oddin. wait at least 3-5 second to go to download mode, this is not happening immediately. If it fails or a half download apeers (with two pc screens showing and say connect to kies etc, press and hold again three buttons until it goes to full download )

2. method : take of freezer, put card, battery, press only power. If vibrates and go to download mode connect to pc where you have oddin ready for flash

tip. every time you open oddin> right click> run as administrator

I found solution with first method.

card I used was a 16 Gb class 10 kingston card and also a ADATA 16 Gb class 10 card ( I had used 3 different so far)

I thing that anything more than 8gb will do, but I know for sure 16 or bigger is working.

Tonight , after 2 days from the fix , I took the courage and rebooted my phone :)

Thank god it rebooted normal without problems

Wish you luck my friend

After keeping 1.5 Hr in freez odin failed on 50%.

Ext4 write failed.

but you are in a good way, that mean its method is working

I reached from 30 to 60 % sometimes.

Finally in the end it passed. Problem is to write that boot.img.ext4 , after that almost certain it will finish succesfully.

I also have a W8

If your phone was not in MTP USB option or was not able to connect to pc before it bricked (the same as mine) I think we're screwed...

I've tried the freezer trick & it doesnt work.. I'm not sure what this sd card "fixes" but its defiantly has nothing to do with the mode the USB is in. If there is a file to change this USB option before the phone boots to download mode then maybe we have a chance @ fixing them..

I installed this program. Last night and phone work perfect.

Thanks

I am rooted on factory firmware!
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
Let me ask you something . Since I have debrick my phone i have left the sdcard (with the boot files in it) inside the phone.

I have done it because every time I try to reboot phone with the card removed, phone can't reboot. Turning black and thats it.

If i have the card in it, no problem, phone reboots normally and everything is OK.

Also I can never put phone to recovery mode (stock) by pressing volume up + power+ home.

That makes me think that recovery of the phone is corrupted and cannt be fixed.

I would like here to ask your opinion about this:

As I can, using the recovery sdcard, to boot in download mode, do you think I could risk trying to do so and from there flash TWRP through odin?

Have anyone tried it ever?

Any experience of that kind will be appreciated :)
[Galaxy Note 4 Android Development (Snapdragon)] alquistador:
I am running TWRP lastest version. I will try your request and repost then
[Galaxy Note 4 Android Development (Snapdragon)] kojam:
This may be just what i'm looking for!

I have had trouble with the phone after it locks from inactivity. The damn thing wouldn't turn back on. NOTHING worked...back into the freezer for few hours, back on charger, then it worked after several tries..happened a few times in the past few weeks. Really upsetting me...This may do the trick!

As well, if i did come out of the black screen to use it again, it would some times just freeze up and either continue working after a short freeze, or just shut off...requiring the freezer again...

I will install this app tonight!

I will also look for a permanent CPU wake (if one exists).

Thanks all!

Rooted running TWRP. No SD card since it has been de bricked
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
did you had TWRP installed before bricked or you installed it after de brick?

If after, how did you did it, using sdcard to go to download mod and then flash TWRP with odin?
[Galaxy Note 4 Android Development (Snapdragon)] alquistador:
I removed the SD card after I use the de bricked image the first time. Root and TWRP were done with Odin.
[Galaxy Note 4 Android Development (Snapdragon)] kojam:
I agree. So far so good. Installed as soon as got home from work no issuse at all. By now I'd usually want to kick it's butt .

The app has upto 24hrs and an UNLIMITED option I got it unlimited, of course.

Will report back.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
so, let me ask just to be clear.

Your phone without sdcard can go to download mode, right?

So you was able after debrick, shat down phone, then start phone in download mode and with odin flashed twrp and flashed SU .

Is that what you did?
[Galaxy Note 4 Android Development (Snapdragon)] alquistador:
Yes that is correct.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
my problem is that without the sd card my phone cannt go to download mode either to stock recovery.

In fact a while ago, while was waiting your reply, i tried that.

Shuted down the phone and press volume up +home+power for recovery but nothing, Phone vibrates but black screen. Then tried download mod without sdcard, again nothing. Tried to just powered it up without card, NOTHING.

So back in the freeze for 5 minutes put sdcard back in and fortunatelly rebooted with no more problem.

That is why I hazitate to go to download mode (with sdcard) and flash TWRP. I am afraid that, even if it successfully flash TWRP, I will not be able after that to reboot in recovery again.

Maybe I have to stay for ever in stock rom.

At least i have my Note 2 rooted and with TWRP and can play with it .

I just would love to flash a custom rom to Note 4 and unlock all this power hiding inside it.

Do you know that my Note 2 works almost better than the Note 4 , because of the custom Android N 7.1.1 rom in it?

Its a shame all this power to stay lock in a stock rom full of bloatwares:(

Any way thank very much for your answer. At least with CPU Awake , phone is working pretty well so far.

[Galaxy Note 4 Android Development (Snapdragon)] logosA:
Is your phone working normally after you have debricked it? Do you think rooting it and installing TWRP , made it working better and without these stacking and freezing problems anymore? Are you considering your phone as a fully debrick one?

Because I am thinking of rooting it and install TWRP , in order, after a while, to proceed and flash a custom rom in it, thinking that this will prevent phone from bricking again.

Would that work do you think?

What is your opinion about that?

It does not make a difference. After I debrick the phone works fine just cannot restart or turn it off. I think the problem is in the DM verify. When I Odin the root file I get that error. I am reading some stuff on the internet about it.

Quick question: Does a SIM card need to be in the phone during the debrick with the SD card? So far my attempts have been to put my W8 in the freezer (without SD/SIM/battery) overnight, take it out, insert the SD card, insert battery, hold power for 10-30 seconds (also tried holding power + dn) and nothing. No vibration, nothing. I've tried about 10 times already but I'm not giving up yet.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
No, sim card is not required. I did all that without any sim card and only when phone was debrick, putted a sim card in it.

P.s Download mode is volume down+home+power. I know you know that, but just because you wrote something else, i am mentioned it, just in case
[Galaxy Note 4 Android Development (Snapdragon)] thepez:
Thanks. Out of curiosity what brand/model of SD card did you use? So far I've tried a Samsung 32GB SDHC I, Kingston 32GB SDHC I (10) and am about to try a SanDisk Ultra 16GB SDHC I. Also, was the vol dn+home+power the method you used? If so, how long did you hold down the buttons? I've tried 10 secs, 30 secs so far.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I used a Kingston 16 Gb class 10, and an AData 16 Gb also. Both of them made my phone goes to download mode. Cards where nothing special or extreme and i dont think thats the problem. Thing is for the phone to just read the files from there and go to download mode. After that you can just remove it.

I pressed and hold that compilation until phone to vibrate. Most of the times although it vibrated didnt start download mode but then i let go and press again until it finally did.

It finally did When the phone was cold and just out of the freezer after 6 hours.

My biggest problem was not to get it to download mode but after that to be able to flash the files with oddin. There was the problem for me
