Sure! The fact it's so big is because it has to be done with a 4GB SDHC SD card as told by Samsung inside [see (14-96) Boot Recovery Guide_Qualcomm_APQ8084 (includes SM-N910F) Rev 3_0.pdf, page 2: Pre-requisites

1) Micro SD card

→ Type of SDcard should be ‘SDHC’ or higher type, and capacity should be

4GB or more ]

Since I used Win32DiskImager-0.9.5 to create an image of the SD card it took the full 4GB capacity. It doesn't left out the empty space.

guys I would like to ask you this.

In your opinion, this is a hardware issue or a software?

This thing with the freezer leads to hardware, because freeze would not matter software, but after loads up, phone seems to not have any problem, so where exactly is the problem you think?

Also did any one of you, after debrick, tried to flash TWRP and faced same problems again(eMMC read failure etc) ?

guys a new thing happened to me today. The phone after a message in messenger (FB) crashed and wouldnt start again.

Took of the battery and with the ext sdcard (I have always in the phone any more) managed to start the phone up

Put it in the charger and left it there while i was doing some other work

After maybe an hour I heard the messengers sound again and went to check my phone.

I saw something that I have never seen or heard before

KERNEL PANIC

Have you ever seen that?

upper left corner with red letters says:

Hernel Panic!

Wait...

Done!

UDC START

In the midle of the screen the green android and message

KERNEL PANIC

UPLOAD MODE

Have ever seen that?

Freeze it and install an asop ROM.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
i just installed twrp on it and i am in recovery right now

Can i write an aosp rom in nternal storage and flash it from there you think?

I am able to see phone with my pc and can write files in internall storage

Do you think i can try it?

what rom do you suggest? Have you tried RR 7.1.1
[Galaxy Note 4 Android Development (Snapdragon)] alquistador:
I think you have to down load/have it on the phone SD card internal or external and install in recovery
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
after i failed to flash again with odin the recovery files, I decided to flash twrp. I tried and succeded in the second attempt. Now i have connected my phone to pc, its in recovery mode and I am downloding the nougat rom from RR for our phone. I dont know if i have to freese it before flash it but i am goin to try right now and if i fail i will try to freeze it and try tommorow morning.

At least now i have a recovery which i know how to use it.
[Galaxy Note 4 Android Development (Snapdragon)] alquistador:
Just flash
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
thank man, you have been a great friend these days.

I have downloaded and copied rom in internal storage and now I am downloading gapps ,

in 3 minutes i am starting flashing.

Wish me luck :)

---------- Post added at 04:00 AM ---------- Previous post was at 03:51 AM ----------

ROM and Gapps were succesfully flashed!!!

system is rebooting. I am in RR logo

The CPU durring flashing reached 75 C !

Maybe thats what is making our phone to crash, and thats why when its freezed it works the recovery files

waiting to see if finally will reboot
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I was not able to complete a custom room installation.

In fact I installed three different

RR 5.8 with android n

RR 5.7.4 with android MM

Full Note7 Port for N910F

ALL of them were very well installed through TWRP recovery

they were never able to finish boot up

Always I was caught in logo boot loop of the rom(their logo not Samsung)

never finished up.

Freeze phone and in the morning tried again with customs but no luck either.

When was desperate, tried to flash recovery files with odin as i did in the beginning of all that

Although the phone was not breeze i tried and for my luck it did finished up!

Now I am finishing 2nd software update that phone did find and installing as it did in the first succeeded time.

PS. I used the pit file in the folder 5.11 that was given for Europe pit if i remember correct

Try a 6.0 ROM. The ROM has to match your firmware I think. Emotion or dirty unicorns. Matching your carrier

Thanks for suggesting. Next time I will try. For now I have Reinstall stock 6.01 but this time I have TWRP and rooted with SU

[MENTION=7617599]Trex888[/MENTION] and [MENTION=7132900]yashthemw[/MENTION] , I have read all your posts, followed all the steps provided by you and I was finally able to unbrick my N910F using your knowledge and efforts.

I am very great full to you about that.

I need your advice once more.

After I have tried almost anything possible, the only thing i have find working always, is to keep the formatted sdcard (ext) in my phone so to be able to boot when shut down, or get to download mode or recovery.

I can live with that, since I am not able to do anything else right now and in this way my phone is working.

I have used an 16Gb sdcard which have files needed for that about 4Gb of space. The rest almost 12Gb is an unpartition space that cannt be used from the phone.

Since very often its very convenient to have some space to ext sdcard for files to be stored or back up important others (EFS, modem, Nandroid backup) , could I, somehow make a usable partition of that space without destroying the structure of the card, so to be able to use it as boot and in he same time have the space that i need to take a important back up when for example have to make a full wipe of the phone?

Do you think of anything that could do that or i would destroy this way the necessary structure of the card?

Thank you in advance for your time to read this
[Galaxy Note 4 Android Development (Snapdragon)] Trex888:
Better if you keep this card as a life saver .dont copy or write anything else if you want to use as a debrick image someday.

But if you know the steps how to unbrick then not to worry you can always do the same procedure with a new card as you did.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
thank you, I always have the card in it just in case. I have also made a second exactly the same and keep it as a backup, as you never know.

My phone can never start when shut down, if the card is not in. Also recovery without card is impossible.

But after that it can manage almost everything.

Thank you for your time :)
[Galaxy Note 4 Android Development (Snapdragon)] Trex888:
You have to flash stock firmware with pit file and also have to erase old nandroid in odin options tick on ( nand eraseall ) once firmware flashed go to stock recovery and do factory reset and reboot.

After this you won't required card anymore your device will be normal.remember your device should be cold enough before flashing if your device is hot then let it cool in freezer for couple of minutes (WITHOUT BATTERY) otherwise the firmware will not completely flash because of bricked situation.it sounds crazy to freeze but trust me it will help.

You can download 4files repair firmware from www.tsar3000.com this will comes with pit file.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
i have done it 3 times so far. All times using freezer for 4 to 6 hours each time (I think 5C is the optimal temperature to make it work)

I also have flashed 4 custom roms unsuccessfully (never managed to full boot up)

Today was the third succesfull time i have flashed through odin the recovery files ( BL, AP, CP, CSC) using also a pit file for that

TRLTE_EUR_OPEN.pit.

After that my phone has recovered full and has updated system to the latest available for my region to MM 6.01

Dispart all that i am never able to remove card, because if i do and reboot or shut down phone, it can never come back.

As soon put card in it and press just power it comes back with no problem

Next time i will try that, to remove old nandroid with odin, its the only thing I have never read before.

This moment i am in latest stock firmware and managed to flash TWRP and ROOT it with SU.

This was the first time i found the courage to do it, because in the past I was to afraid to

Again, thank you for your time and your very precious advise

---------- Post added at 12:39 AM ---------- Previous post was at 12:11 AM ----------

as i can see you really know this, so please let me ask you two things.

1. After all that I have described, do you think I can still go with odin and flash stock and remove nandroid and with that I could leave the sd card out? Or leave it now that its working and next time try it, to be safe?

2. Is this a hardware problem and if so, replacing what part of the phone could solve it?
[Galaxy Note 4 Android Development (Snapdragon)] Trex888:
I dont think its hardware problem cuz as you said its running fine while card is in so far it looks like software problem and can be solved easily .If it's a hardware problem then you have to replace entire motherboard.

Leave the card in the device until you finish flashing and erasing old nandroid.

Make sure very important do wipe cache and wipe data factory reset after flashing.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
thank you very much for all that you have told me.

I will rest my phone and myself for some days and after that I will try and do what you said

Flash stock rom and erase old nandroid . I will read and find any more informations that I could learn for this method and try it.

Do you think the pit that I have already mentioned and has worked for me would be the right to be used again?

Again a very big THANK YOU, for all you have told me:good:
[Galaxy Note 4 Android Development (Snapdragon)] Trex888:
If the pit works for you before then you can use again no problem. Just do the same procedure as you did but this time you have to tick on "nand eraseall" in odin options and do data factory reset after flashing.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
Your posts as well as, the OP's [MENTION=7132900]yashthemw[/MENTION] , posts, were very helpfull to me and teached me what I had to do so to be able to unbrick my phone and I will be always grateful to you about that.

Since other users are reading these and looking to find a solution to their phones i am a little more detailed in my posts so to be able who ever is looking, to take as many informations as he can to use for his phone too.

I have a Samsung Note 4 N910F , INTERNATIONAL (european version) and was able to use the files from the ops post and then downloaded all the files that [MENTION=6949733]dyasten[/MENTION] has posted in the pastebin forums and finally use to unbrick my phone

Every one that have similar version of the phone and Android 5 and bigger can use these, otherwise it may not work for him.

My phone had Android 6.01 the moment it was bricked and that worked for me ,too.

Just after was able to restore it, it searched and found all the updates to bring it back to MM and right now I have the latest available for our phone.

I just want here to write some of my thoughts that i have understand doing this.

The sdcard helped me to be able to get to download mode and (after several unsuccessfull attempts) managed to flash all 4 of the files needed to make my phone reboot normal.

Also i was able to do that, when used a PIT file also provided in that pastebin folder.

That pit file was for german Vodafon and worked for me as I use same service provider.

If you want to use a different region or country or provider you can search google for pit for note 4 which will lead you to samobile where you can find a different pit file for your region and country. thats why in my phone it shows country german but everything is working just fine.

It doesnt make much difference as I understood , it will only affect any future OTA updates from Samsung ( I dont think there will be any )

So, used the pit and all the 4 files in the folder (BL AP CP CSC) and Unbricked my

COLD

phone.

I didnt checked nand erase all, as [MENTION=7617599]Trex888[/MENTION] has mentioned me last night, because never had seen that written before and so now I have to have the ext sdcard in my phone , in order to work. But next time I will, as now I have learned it.

Why method of the freezer IS WORKING?

When experimented with custom recovery, I noticed that during flashing the files of a rom , in TWRP was able to monitor temperature of the CPU.

When the phone was NOT FREEZED before, it reached 75-80 C !

When had putted in the freeze before reached 45-55 C .

I think the same thing happens in ODIN as well, so this is why it fails. Phone is stopping just to prevent damage of the CPU or board ( something like thermal protection)

When phone is pre- freezed , that prevent it from reach that high temperatures and so its able to finish flashing.

I would like again to thank everyone that has helped me take my phone back and learned so many things during this process. i am sorry for that long post.

My N910F was bricked. I stuck it in the freezer for 2 hours. Managed to get it into a strange download mode that looked like this:

http://imgur.com/a/IeKru

I opened ODIN and flashed the recovery firmware (AP, BL, CP, CSC and PIT). It failed first time around. I tried it a second time without the CSC and it worked! :D

So happy that my phone is working again. I really appreciate this post for helping me solve the issue.

Unfortunately I am still experiencing the lagging/freezing issue and the phone requires the WakeLock app to work properly. Is there any fix for this issue yet?

Thank you again for all of your help!

If you have a bricked n910t, that means it won't go in fownload mode nor in recovery.

Has anyone of you, monitored CPU temperature and battery concumption AFTER debrick?

I am making a test my self by monitoring apps in the background, what makes CPU work/overheat.

Twice when received a messenger message, phone (which was idle ) crashed and kernel panic appeared. Since then, I have uninstalled FB, messenger and have disabled almost all Google bloatware ( movie, music,books etc) phone is working almost perfect, battery increased 50℅ and CPU is working maximum to 40 C.

Hey, I'm having a bit of trouble since my last response. I successfully managed to get the phone back from being bricked by putting it in the freezer (I did not have to make an img on the sd card). I then flashed your recovery firmware files: http://imgur.com/a/CYySw

Initially it did not work so as you recommended I didn't include the CSC and then it worked. This is when I left my last reply to you.

Since then I attempted to flash a MM Stock ROM from Sammobile using Odin: N910FXXS1DQA2

Unfortunately flashing this ROM failed and the phone only gave you a messaged saying "Firmware upgrade encountered and issue. Please select recovery mode in Kies and try again." so I attempted to reflash your recovery firmware again through Odin. These repeatedly failed in Odin at various stages.

I put the phone in the freezer again overnight and the next day I attempted to flash your recovery firmware like before and it succeeded. Unfortunately now I get the "Galaxy Note 4" Splash Screen followed by the pulsing "Samsung" logo but it just sits on the Samsung logo (not bootlooping, not freezing. the animation keeps going). Stayed on Samsung logo for several hours and then powers off.

I put the phone back in the freezer and flashed again. Same story. Stayed on Samsung logo for 2+ hours.

Can you please advise what I might try here?

Thanks again!

Have you tried resetting the device via recovery?

Reporting Via N910G.
[Galaxy Note 4 Android Development (Snapdragon)] piratezilla:
Okay I managed to get it into Recovery mode but it had the message "failed to mount /efs" under the list of options. I did a factory/data reset and then it returned to the "Firmware upgrade encountered an issue...". I tried reflashing your firmware again and it failed so I put the device in the freezer for a while. Took it back out, flashed the recovery firmware again and it succeeded. This time it booted up fine.

After powering it off it wouldn't power back on or respond to any button presses. I have to take the battery out to get it to switch back on. It will boot up and I can get it to Download Mode. I cannot get it into Recovery Mode though and when I try to it just goes to Download Mode with the error message: "Could not do normal boot. ddi: mmc_read failed".

Any further advice? Thanks!

---------- Post added at 04:05 PM ---------- Previous post was at 04:00 PM ----------

After getting into that version of download mode with the "mmc_read failed" error it will not fully boot now. I only get the "Galaxy Note 4" screen to work for a couple of minutes then the phone turns off. The battery was at 84% when it booted fully a few minutes ago so that's unlikely the issue. Now the phone won't turn on at all, even after taking the battery out. I would guess it would come back if I put it back in the freezer again.

Do you foresee me being able to get this phone back to a workable state? Is it just a lost cause?

Thanks

After taking it out from the freezer, flash the recovery firmware.

Once it boots, install wakelock and select the 'never doze' mode, i dont remember what it is called specifically but it should prevent your phone from entering deep sleep mode.

[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I have managed, after a lot of unsuccessfully attempts, managed to unbrick my phone ( we must all accept that there is something wrong in the hardware of our phone that cannt be undone).

But some things can keep it working at least for some time.

1. Wake lock. Don't let your phone go to deep sleep. It usually it cannt come back. Two tested apps can do that, check screenshots. I preferred CPU lock as for me it's working the best.

2. Uninstall all power saving apps like greenify, or purify. They usually put phone to sleep to save power. We don't want that!

3. Install TWRP and then root your phone so to be able to disabled and remove if possible any bloatware that you can Google movies, music, books etc. Also consider to not use FB or messenger App. If you need them keep them in browser.

4. Use an app from play store called disable APPS and disable everything you can't uninstall.

5. When away from wifi disable wifi. Your phone tries and tries to connect and finally freezes.

Also mobile data only when necessary.

These all are things I have done to my phone and for now I think I have got it back in an acceptable contition

Yes you have to put your device in the freezer with the sdcard.

Although, i think, it wont make any difference.

But remember, before taking out the phone from freezer, all the prerequisites should be ready.
