keep trying, since you have come this close you will be able to finally manage it.

Good luck my friend :)

when using smart switch, try freezer again.

Or skip smart switch and go with odin or auto update . It may be better.

But dont give up, you ve got this :good:

RE

Hello,

Thanks for this great forum!

I have an N910F, which is HS: /

I tried following the procedure ...

Driver Ok -> Drivers are well installed, and portable Laptop well recognized "Qualcomm HS-USB QDLoader 9008"

I create well on the sd correctly, as shown.

But then it is impossible to have the download mode. I press very long the low key + home + power ...

The laptop does not turn .... so should not read the SD card?

I tried to change SD card + cable + port + computer computer .... same problem!

As soon as there is an SD card in the laptop, I connect it to the computer, in the device manager I no longer have "Qualcomm HS-USB QDLoader 9008", and nothing new.

What can I do ? thank you

When you put your sd card in you phone without plug it to PC, press the power only button.

DOES IT VIBRATE? If not there is no meaning plug it in the pc , phone has NOT read the sd card so to be able to go to download mode.

So freeze your phone, put the sdcard and battery on, press only power and see if it vibrates.

If it does, put it in the wall charger and wait for 10-15 minutes.

If its not starting take off battery and card and freeze it more and try again.

If phone is NOT vibrating, cannt go through the pc recovery process

Hello to all of you, I tried this method on my note 4 n910f with the related img file the phone vibrates but i cant seem to get into download mode. If i press the power + home + vol - longer it continues to vibrate but nothing happens and if i let them go a blue led turns on, the phone gets recognized by pc and then i think it starts to charge with the red led on. The thing is I couldnt get this without trying the sd card method but now this process is present even without the sd card. What I wanna ask is: Do you think there is still a chance i might get it back or the emmc has failed ? and the only solution would be a new motherboard..
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
Your phone

is working in the background

. I dont think sdcard is your problem.

Try recovery mode to see if it works (volume UP + home +power)

If it does go to recovery try factory reset, wipe cashe and dalvik and then reboot your phone.

If it does that, your phone will come to life one way or another.

Also, as you say the led is working , that means the phone is charging. Let it there for an hour at least to be sure your battery is charged before try what I told you

guys Guys GUYS!!!! BIG BIG UPDATE!!! But first let me start from the beginning; I bought this note 4 n910f as not working with a "dead" motherboard cos the seller said that he has faced the usual symptoms of rebooting, lagging and then one day the phone has refused to turn on. I bought a motherboard of verizon(thinking its model F), tested the phone worked perfectly but returned it cos of it being from verizon and then I started to search for hard bricks of note 4 and came to this beautiful thread <3 <3 Now since I put the original motherboard of the phone back, not paying much attention the display cable hasnt been connected and because of that I was having vibrations, blue(recovery light) with the method mentioned in this thread but nothing on screen so I thought of controlling if I have left anything unconnected when I last installed the motherboard (GLAD I DID!!) aaaaand then I was able to get recovery, download mode on screen ^_^_^_^ Now the phone is working perfectly!! Im not sure how much this method helped or even if it helped at all (cos I saw there was no juice when I installed that verizon mb and today I charged it for a while before trying this method) but one thing Im sure of is that the phone wasnt charging/red led on while having it on wall charger. So yeah maybe this method helped it to get to its senses ^_^_^_^ THANKS TO ALL OF YOU!! WAY WAY TOO HAPPY RIGHT NOW!! <3 <3 <3 You have screenshots as a proof :) :) :)

Btw Im skeptical about installing the update I got x)

I finally managed to install a firmware and restart the phone. I thought I had solved, I upgraded to the latest firmware available via direct cell update. After 2 hours of inactivity ... I see that the phone is switched off ... back to the same point as before. I also get back 30 minutes in the freezer and resumes. But there is a way to stabilize the situation and to properly operate the phone ... without putting it in the fridge ??? Very frustrated ...
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
install this :

leave phone to work , in the background for some time rom is working. setting, settle down. This proccess can tike some time, even a day until everything is done.

Good thing is that your phone has come back to life.

Other things you will be able to do later. Dont celebrate just yet, you have way to go
[Galaxy Note 4 Android Development (Snapdragon)] landingview:
after two hours in the freezer I restarted the cell and reinstalled the firmware that you have indicated without further updates I want to see if by that the situation is stable and there are no crash. I downloaded the app and activated for an unlimited time. I have to do on the phone? Currently installed N910FXXU1DPH1 I hope not give me other problems. There are other tools that I can install to verify the situation of firmware and correct any errors?

---------- Post added at 11:05 AM ---------- Previous post was at 10:07 AM ----------

On smart switch:

current version PDA:PI1/SCS:PF1/PHONE:PH1 (VD2)

new version PDA:QA1/CSC:PJ2/PHONE:QA3 (VD2)

May be ok the current version?

---------- Post added at 12:03 PM ---------- Previous post was at 11:05 AM ----------

nothing to do, I installed the application that you have advised me, lasted an hour or so after that it was off by itself and will not turn back. Pressing the power button does nothing but the vibration screen. This always with the micro sd inserted. Without that added nothing to do ...
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
All things you have mentioned I faced them too.

After my search around i have come to this conclusion

1. Stock rom is the only that can keep your phone working

2. Custom roms available at this moment have problems which are enhanced with the hardware problem that our phone has. This problems are : random reboots, freezing and laging so similar with the hardware symptoms of our phone that you cannt really say what is from what (from software or hardware) . so some times software reboots make the phone to not be able to boot again, except with the freezer method.

This is why FOR THE MOMENT, I prefer to stay on stock rom.

3. If you leave stock rom the way it is, your problem will not be solve, also you have to understand , this is hardware and canNOT be solve for good , unless you change your motherboard.

SO WHAT I DID

I run the recovery proccess twice (2) the set of 4 files with the pit as I have described in my previous posts

After that I flashed the latest stock rom as I also have told you.

The first night I left my phone , it was found closed , like yours and also cpu wake could not solve the problem.

So i have installed twrp and rooted the phone and have freezed all apps from stock rom that I think are the problem for that shutting down after 1-2 hours.

Phone now is operating ''normal'', doesn't shut down and have no problem at all , except when i decide to power off, which means I have to put it in the freezer for some time to get it started again.

I dont ever use the phones menu to reboot , recover etc

i use this

https://play.google.com/store/apps/details?id=simple.reboot.com&hl

I have freeze all system apps mentioned here:

https://xdaforums.com/showpost.php?p=58541172&postcount=2

(I have used titanium backup to do that). This post was made for lolipop but its the same apps in MM as well.

thats what i am doing now and thats how I have still the ability to use my phone.
[Galaxy Note 4 Android Development (Snapdragon)] landingview:
The last clarification please:

1: one I have installed, the N910FXXU1DPL1 is a stock rom. The last update that asks me to install fails, it gives me a problem (or maybe I could succeed putting it back in the freezer and immediately after launching the update. The latest firmware precisely the N910FXXS1DQB4 you should install it (always with freezer)? So the problem with these motherboards is still hardware? the component in question is the IC Power Manager? you know the component name and you can think of replacing so as to solve the problem 100%? is it worth it?

This TWRP thing more on the phone?

With that application will reboot and all the other functions do not block cell phone and avoid putting it in the freezer?

Thanks to all these explanations

:)
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I am using now that exact version. I downloaded and installed it directly with odin as i had previously formatted my system and had install a custom rom. So when custom rom failed and gave me same problems, i used odin and flashed this latest stock rom. This time didnt use anything before, no pit no other settings. Of course i had freezed my phone again. So full charge your phone , stop other precesses that may run and try to make the software update again. The TWRP is the custom recovery that i flashed after that, so to be able to root my phone and then be able to freeze the apps i was talking about. So dont be afraid of the update, its not the problem. Our hardware is the problem
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
I have found more than 5 threads in xda talking about these problems with Note 4

I have count my self more than 100 users posting about that (that means 2-3 times more that are not posting, just reading)

I have read posts where users said that official service have confirm that this is a motherboard hardware problem starting to show after the first year of use and have replaced to customers that were inside the 2 years guarantee (europian rule) the motherboard of their phone and that have fixed the problem.

In case you think to replace the motherboard it is 100 € (second hand in ebay) which there is no guarantee that is not a defected one

If you want the official service to replace it, you need more of 250 €, so not worth it I think

So lets try and do our best to keep that one we have as active as we can. We dont have any other choice (at least I cannot afford it)

take a look here if you like to see what we ARE talking about

I was afraid to put note4 in the freezer!:p

Incredible it vibrates!:o I followed the steps. Nothing on the screen, but Odin detected it.

But when I wanted to flash it, as indicated on the post, I have this message

I will try changing port usb2?

Thank you again for your help.:angel:

Keep it in freezer, for about an hour.

Before removing it from freezer, Keep everything ready on odin.

Once you take it out, quickly flash.
[Galaxy Note 4 Android Development (Snapdragon)] RishiChhikkara:
i flashed the latest firmware from sammobile, it flashed properly, still freezing though, i think it won't let me flash recovery firmware since that one is Lollipop & i am on marshmallow, something to do with "boot loader can't be downgraded"
[Galaxy Note 4 Android Development (Snapdragon)] logosA:
You mean that you have flashed the latest stock rom?

If it was flashed successfully , why want to flash recovery firmware again, since your phone is working?

Install cpu awake and let it update and settle down for a day maybe.

After that, rom maybe behave better, if not, You will have to flash twrp, root your phone and freese all apps that making it laggy. You can find a list with all that here:

https://xdaforums.com/showpost.php?p=58541172&postcount=2

its working for Lolipop and MM roms
[Galaxy Note 4 Android Development (Snapdragon)] RishiChhikkara:
i tried to flash recovery firmware because it cotains pit file, which would re-partition emmc, with a slight chance of overcoming this emmc bug, but i did that already with the separate pit file, thats not a problem & particular apps aren't freezing my mobile, its freezing even when i try to reboot to twrp or even while simple booting, it would literally stay at twrp logo & note 4 for like 4-5min sometimes, i think its a hardware problem.

yup, infact that's what i am running right now, fortunately i have another HTC M8 , will use that one for some days ,i have performed heavy debloat on note 4 now , only few apps remaining now(see the screenshot), will see if there is any improvement with this, otherwise we have a very famous local market( Gaffar Market). i'll take it there & will sell it for parts.

I bought it second hand from a guy, knowing that it was bricked but didnt knew what the problem was.

I took it for 70€, which is nothing comparing the price in our market now (300-350€).

So i ma not going to lose so much if it totally breaks. But i feel sorry for a device that good o be bricked.

I have my Note 2 running perfect for 2,5 years now so I dont really have a problem with phone.

I have learned so many things trying to unbrick it though. Maybe thats the greatest thing about all that trouble :)
