1. after you format the sd card, partition master can only show you if the partitions in the sd card is as they have to be.

In my case (i have a N910F) it shows like image 1.

I believe your should shows something of this kind also. The files will be writen in the sdcard and all the remaing space will be a big unpartition space. If thats not happening you have to re-format the card and try again. The problem is that in order to do that you need another android phone with Android 5 or bigger that can see the card and be able to formate again so you can go back to Win32DiskImage and wright again the files.

I have find a solution that helped me format this card again and don't have to put it in a phone and back in pc.

There is a program called SDFormatter that is made exactly for this job. Allows you to format your sd card with a pc, The exact description is SDFormatterv4(icon 2), its free and you can search Google, find it and download it in your pc.

When the card is formatted with Win32DiskImage, you cant see the whole card and format it with windows.

So sdformater comes here, format your card and restore its whole size. (for example my sd 16gb card was seen from windows as a 3.4 GB , which was the size of the debrick file and the rest of the card, could not been seen , or formatted. Just make sure in sdformater option to check

FORMAT SIZE ADJUSTMENT

to ON (icon 3), to restore the sd card to its original size. After that , format it and put it back to Win32DiskImage to create the unbrick card.

2. you don't put the sdcard in the freezer with your phone. Its not as strong as phone and moisture may destroy it.

Just phone without card or battery in a zip bag( I use two zip bags one inside the other, just for insurance)

The freezer is working because is holding the CPU temperature in low levels so to not overheat during that process and shut down for thermal protection and its most needed when flashing files with odin mostly. But it doesnt heart in the debrick process with the card as well.

So if sdcard is not enough you have to use oddin and flash the full recovery package of the 4 files given.

after that if the phone doesnt download and install the last available firmware by itself, you may need to find it from samobile or samsung and after again freeze your phone, flash it with odin.

All that things I have learned and tried many times , until to be able to recover my phone in an exceptable condition. Its not perfect , it still looks fragile , but its working

Good luck my friend

Hi [MENTION=5554397]logosA[/MENTION] ,

Thanks for your kind reply ....

I have kept the device alone inside Ziplock and in the freezer for whole night (around 7-8 hrs).

i have just re-formatted the SD based on the software which you provided (Thanks for that) but unfortunately i could not find any partition similar to the file for N910F (provided in OP)..

I have used the image provided in the OP for N910G(17.9 MB) and the partition doesn't look the same .

Can you please verify the attached and let me know if the image is correct and i am ready for the flash ?

Thanks

just saw you phone is not an n910f so dont use my files
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
There isnt any huge file in the n910f debrick.img, it is just a partitioned space.

A few people with n910g were able to fix their phone with the 17mb. So it is working.

Dont use any file that is meant for n910f.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
[MENTION=3686052]vndkmr97[/MENTION] as OP is saying above, you phone's debrick process is totally different than mine so please dont use my method

Make sdcard with the unbrick images that OP is providing in his posts and put it in your phone and wait until you see some activity in the phone. Some times it takes even up to 5 minutes until phone start, it doesnt mean its not working in the background

So have some patient and see what will happen. If you have followed the instructions on how to make sdcard it will work.

If the phone doesnt completely unbrick but somehow manage to get to download mode at least you will have to take the recovery files for your phone from here and flash it with odin.

Guys, if you have problems, restart/ reboot your phones. Simple reboot or Reboot in recovery, Try this app I have tested and it's working flawlessly. Even can reboot in TWRP recovery from inside the stock ROM that I have in my phone. Tested every option and it's working for me. Of course, root is needed.

Name as you see in title is Simple reboot and it's free from play store

[MENTION=7132900]yashthemw[/MENTION] i have similar problem of reboot loops cannot even enter recovery but i can get to Download mode (odin mode), maybe you advice me.

1. tried flashing using odin/kies , cannot boot into system or recovery. about 5-7 seconds into booting it will reboot

2. tried put in fridge 5-10mins, able to boot to system (only tested system, too late now to try anymore... 4am now).

3. when in system, phone starts reboot loop after a while...

4. tried to cf-autoroot... same thing reboot look after the recovery part starts...

5. question, recovery frimware... need to boot into system for it to work?

1st time i've heard the need to put in fridge, but it works... what do you say...
[Galaxy Note 4 Android Development (Snapdragon)] yashthemw:
From what I understood, you are asking, whether the recovery firmware can be flashed if the phone is not booting.

Yes you can flash the recovery firmware.

Read the correct method of flashing a recovery firmware in the op.

I tried to flash recovery firmware 3 times yesterday, but did not boot.

Will try freezing and boot after flash tonight.
[Galaxy Note 4 Android Development (Snapdragon)] felix_fx2:
Decided to flash TWRP and put in freezer for 15mins... then flash custom rom...

When in TWRP i saw CPU tempetures 46-50c.. managed to boot into custom rom, check tempreture again when idle 39-48c...

when try to reboot after reach room tempreture, same bootloop happen :crying:

can someone share with me working N910G idle temps ? maybe is overheat... should i freeze longer (1 hour) and try repair frimware (india frimware) ?
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I have twrp in my phone. Tried 3 different custom roms, never managed to accive a complete boot up in any of them.

The idle temperature must be no more than 40-45 C

If processor excide 60 C for more. Than 2-3 minutes , expect a freeze or Reboot in your phone.
[Galaxy Note 4 Android Development (Snapdragon)] felix_fx2:
Update, thinking cpu over heat i think of idea.

i freeze 30minute made it boot to system, then retighten the screws around power button. (cpu is around there)..

now managed to stay booted for 2 hours, but idle temps still 45-50C.. but no reboot loop..

now stress testing with some games see will induce reboot loop..

thank you people.

an icy thanks :)

awesone stuff [MENTION=7132900]yashthemw[/MENTION] !

2hrs in the freezer and it booted up.

I placed a brick of ice on top of the note 4 while it was flashing away and seems to work good.

flashed dr ketans rom but somehow, still need to put in the freezer some times as it gets stuck and does not boot up, no led light nothing. taking out the battery does reset it either... something is wrong with the booting of the device.

i have some things to ask everybody in the group that have any nowladge of, or have tried or have read something to help me.

I have a note 4 N910F , which when i got it on my hands was bricked. Black screen and all.

With the help of this team, a lot of reading and many many hours of trying and trying and failing, finally I managed to unbrick it, using the start up sdcard with files and instructions provided by the OP of this thread and external links also provided in OP posts, flashing recovery firmware ( 4 files and pit) and after that phone has updated to the latest firmware available for our phone in MM.

At this moment i have SM-N910F / N910FXXS1DQA1 rom installed in which i have flashed TWRP and rooted with SU.

I have frozen and uninstalled a lot of bloat wares reading posts and threads all over XDA and i can say that my phone is in an acceptable condition but also facing a number of problems, other users, as I am seen, are also facing.

1. I use cpu wake lock to stop my phone from going to sleep because other wise it never wakes again if i dont freeze it first.

2. while intensive use of the phone it gets hot and some times freezes of shut down.

3. This is my major issue which I dont know how to solve. When made the process with the external sd card so be able to de- brick it,

I had left it inside the phone all the way until ODIN has flashed files.

Now I cannt reboot or boot in recovery unless the sd card is on the phone. With the card inside the phone, everything is OK.

I have decided to move on and try to flash a custom rom and see if i can solve any of these problems

Before manage to unbrick the phone with official rom, i did tried and flashed 4 custom roms (1 MM and 3 Nougat) to see if that could help me. Not once managed to boot up all the way, to any of these roms, although everything was successfully flashed with no errors ever, just not competing first bOOT, until phone got so much heated that rebooted.

So I gave up and finally stock rom did the job.

Now as I have told you I have decided to try again. The dilemma that I have is: Should i go and flash custom rom and gapps right now or first flash Stock Rom with a pit, removing all old NAD backups so I dont have the need of the ext sdcard any more?

Will just flashing the custom rom remove that what is making my phone to need the sdcard, or its nessesery first to flash Stock rom removing old nad backups, otherwise its not going to make any difference?

I AM VERY SORRY OF THE SO LONG POST.

but

I desperately need another thought and opinion or experience I dont have

Thank you all for having the patience to read all this , any opinion will be very much appreciated
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I have tried all that i have written before. Tried flash stock rom with pit> failed 4 times at the end with message. "" sizeToo big "" i think the pit i was using was wrong.

I also tried 2 custom roms

RR 5.8.i

EmotionOS 20.2.17

Both failed.

RR failed giving message ''fail to write system"" error 7

Emotion got stuck in flashing system for more than 15 minutes 3 times.

So i went back to flashing recovery files which succeeded and now i am trying to boot without the use of the sdcard, but it doesnt seem possible.

BUT THE IMPORTANT IS THIS :

I found a way to Not put the phone in the freezer for hours until be cold again and try back. In fact i flashed 5 times one after the other with no problem at all. The idea was given by [MENTION=299752]sonhy[/MENTION] 2 days ago when he mentioned ice, which he used to keep phone cold by putting it on top of it.

I reverse it.

TOOK AN ICE CUBE VESSEL FROM THE FREEZER

put it on a zip bag, took of the back cover of the phone and put it on ice. This way, 2 hours now my phone is flashed constantly with no problem, as the CPU is laying on ice and its 35 C all that time

Finishing now recovery of stock sgain, but now i have the method to keep going.

Take a look and keep it in mind for future

I think, it is a hardware failure for sure.

There was one n910g user, that I remember of, who managed to debrick his device.

I think his username was abhay210.

He was the one who came up with that 'freezer' idea here, which did worked out for many. You can ask him.

Read some previous posts of this thread and you will find him.
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I am doing another experiment and want to share.

I have thought that the problem may not be the CPU , or just the cpu for freezing or rebooting phone.

It may be GPU , or maybe GPU as well.

I have many times tried to tune the kernel, to see if that could help phone from freezing or rebooting. I have used kernel auditor or thunder zap control, apps that let you modify cpu and gpu setting. With them i have seen that I can very easily change the CPU setting from ex interactive to performance with no problem at all. BUT, the moment i touch GPU always phone reboots.

That made me think to look a little closer the gpu and its setting.

I have found this:

https://xdaforums.com/note-4/orig-development/adreno-420-drivers-note-4-t3546566

Here i found and installed the laTEST drivers available for adreno 420, our gpu drivers

The people there are claiming that flashing their flash able zip through TWRP recovery, updates the drivers of our GPU and in this way its increased speed, smoothness and performance of our graphics card.

It can be applied to every MM rom, official, stock or custom if only its rooted and has custom recovery

So i boot in TWRP recovery and, as they strongly advise, cleared cashe and dalvik/art , flashed zip and

again

clear cashe/dalvik>reboot

I cannt find any difference in speed, but i did find phone working very smooth after updating drivers.

The most interesting thing though is that ( this is the experiment I was talking about) I have uninstall CPU WAKE LOCK and also I have installed and running GREENIFY (!) which has radically drop the consummation of the battery to under 1% per hour and so far, phone has not freeze or shut down . The temperature of the cpu is now 30 C idle,

Its only 5 hours since i have done this and so far I havent seen any deep sleep or death in my phone.

But since I check it every half our, I cannt say for sure it wouldnt do it over night when I go to sleep.

So , I am testing and will share the results with the members of the thread.

I hope I will have good news to share

Are there any problems restarting ??
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
no restart 24 hours now. I had a problem with camera that crushed and phone freezed for a while, but as I found out i was having changed settings of storage for the photos and had not change the sdcard and still had the debrick card in phone, which is nor writeable any more as all space is occupied from the image.

So phone was trying to save photos in the ext sdcard and freezed for a while.

After changed sd card, phone got buck to normal. But until find that out, I had pull the battery out and rebooted phone by my own. :(

Continuing testing until tomorrow again

Hello Folks,

So happy we have an image for the W8, I used win32diskimager with an 8GB FAT 32 SD to write the image provided by [MENTION=4805013]Valentinez[/MENTION] to it.

Yea my bad flashed over emotion os....did full wipe and now phone is dead lol. Flashed sucesfully all with odin but phone boot loops or only downlad mode works
[Galaxy Note 4 Android Development (Snapdragon)] Thlakias:
"write" the sd card, put your phone to the freezer for a while. open odin tick "auto reboot", "re-partition" and "f. reset time". load the files in bl, ap, cp, csc and pit (in pit find the recovery "AP.....something.pit" and not the "trlte_open_eur.pit") after that put battery on and the sd card. put your phone in download mode and connect it to pc. if you see in odin [blue com] and the pc recognizes your phone then push "start" in odin. wait until it writes PASS! and the phone boot in. if you have a success do it for second time the same from the beggining, if not you must put again your phone to freezer (i think 10-15 minutes are good) and retry.

i did that and my phone works perfectly (i did it two times and i saw that the second time load something extra my phone) and no need to put it again to the freezer and no need the sd card anymore. i flash some stock roms (without to put it again in) and every time odin pass away. my phone now, reboots, shutdowns and made a restart when i selected by myself.
