[Galaxy Note 4 Q&A, Help & Troubleshooting] o0o.paw:
Oh well so much for that theory. It worked great for a couple of hours the started freezing and rebooting again :( I guess that was to be expected.

Samsung have got back to me and said as the phone is over 2 years old I'd have to pay $66 for them to look at it and it was my choice to do so or not.

So they manufacture a phone with a known fault (or deliberate planned obsolescence) that stops working after the warranty runs out then expects you to pay to even look at it. Even if they decided to repair it without any additional charge (and they did not indicate they would even do this) you still have to pay $66 to do so. So you buy their faulty product then they make extra money to repair it.

I know most people replace their phones every couple of years. After using my Note 4 with it's great screen and getting used to having a removable battery I don't want to downgrade to a phone with a built in battery. Maybe I should buy a couple of spare motherboards. I can replace it easily enough by myself but there is no way to confirm if the "new" motherboard is even new and not a stripped out part from a pre-used phone or that it wan't have the same issue a couple of years later.

Australia has had Samsung washing machines burn peoples houses down and then they "repaired" them with a plastic bag after the safety recall (I am not joking about the plastic bag repair either). They've had the note 7 exploding battery issue and now they have hundreds, thousands or maybe even all of them eventually? of note 4's that no longer work.

Great way to get people to not hold onto their phones and to buy a replacement instead :(

And that is why I have not bought a Note 8 as i'm not paying all that money for it to die after 2 years of use. Once bitten...

There's always two Tin Cans and String - lol

I've still got my Skyrocket - Note 2 - Note 3 - Note 4 (emmc issue) - All older devices - S7 (Exynos) and waiting for the Note 8 (Exynos) - There probably isn't a Manufacturer that doesn't have any issues with Build & Reliability ?
[Galaxy Note 4 Q&A, Help & Troubleshooting] Sp0oner:
I still have my S3 which works fine so obviously back then Samsung hadn't started building life limitations into it's hardware. I have bought a Lenovo P2, it has 3 days battery life and the specs are amazing for the money, it cost me £160. If that breaks after 2 years I don't care, what I won't do is spend nearly £900 on a Note 8 when it's possibly only got 2 years life in it. The US Note 4 owners are lucky to get their devices to be fixed for $70, in the UK i've now been told it's £400 for the same repair.

Perhaps if Samsung looked after it's UK customers the same as it's US customers it would have a much greater reputation in the UK.

i have note 2 that works like charm and perfect. what i did it with it that within one year i installed a custom rom and rooted the device and remove all samsung **** , since then i have not updated the device nor installed any new rom even.

but now a days samsung may have been developing motherboard that dies in 2 years so i would not buy any samsung device in future.

but i am sure note 4 is dying after the new update and samsung purposely doing this so that people are bound to buy note 8 (This is what i think you may not agree )
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Um yeah - I understand that's your op and you're certainly entitled to it - My points (which have not changed) - Yes - Definitely Samsung messed up with the design or components in the Note 4 and there's NO QUESTION ABOUT IT - Having said that - The relatively very small number of Note 4 devices that have failed would make it highly unlikely that there was any kind of planning for "planned obsolescence" - Furthermore - Look at the Note 7.... Using your (and others) logic - The Note 7 shouldn't have started bursting into flames for another couple of years ?

Samsung isn't alone with product issues either - Remember the various issues with iPhone devices - "antenna gate" Bending iPhones - Motorola - HTC - LG and most recently Google is replacing an entire model... The difference is that these issues occurred when the devices were still quite new and an extremely high percentage of devices were affected - Which isn't the case with the Note 4 - My guess is that Samsung has a number of parts suppliers and it was luck (or unluck) of the draw which supplier's motherboard is in your phone.

I am getting deal for 64$ on Aliexpress Should i buy this one? has anyone changed motherboard on his own here?

I think i can do it only thing is i am afraid of is that what chances are if the same problem comes again in this motherboard?

EDIT: I found another deal for 59$ Here

You should confirm that the MB is new, never been used. The listings say 100% original, but they don't say they are new. I would be very leery of buying a MB that came from another phone.
[Galaxy Note 4 Q&A, Help & Troubleshooting] zenn-:
I contacted 2 different sellers on Aliexpress regarding N910F motherboards. Both replied that the boards weren't new but were 100% original (pulled from Samsung phones) and 100% working. In any case, the problem may or may not recur but who wants to invest money in a (possibly) sinking ship... Getting a replacement phone was the best option for me.

emmc read fail

i had exactly thes ame problem where my phone would die and i could not get it to work properly, i used odin and tried to flah recovery files, changed the pit, and tried for days to get the phone to start but i couldnt for the life of me get it to work but on one occasion the phone got to about 95% till it got to the bit where it installs hidden then failed. another member on here "hagis" sent me a youtube link that shows how to delite the hidden file and repack and then flash the phone. i did it this morning and the phone successfully flashed but then i got an error that just said no command. i then flashed twrp recovery and formatted the phone, it rebooted and then had the android acore has stopped message. i plugged the phone in and left it for 20 mins, restarted and viola my phon is now working again as it should. its an older official rom that im using but its like ive got my old phone working before the update that gave me all the problems. so ill explain exactly what i did for anyone else that has this issue and hopefully it will work for you

the firmware that i used was

N910FXXS1DQH3_N910FBTU1DPL1_N910FXXS1DQA1_HOME.md5

odin version Odin3_v3.12.3

first off change the name of the firmware to N910FXXS1DQH3_N910FBTU1DPL1_N910FXXS1DQA1_HOME (remove the MD5) and unpack it using winrar. open the folder and delete the hidden file. repack it and put the MD5 back in the name and then flash this on your phone. when your phone reboots and starts to update but you get the no command, put it back into download mode and install twrp and format your phone. restart it and it should boot normally. like i said i got various errors when it had first started such as android acore has stopped working but after turning it off and leaving for 20 mins it started with no issues.

i would attach all my files that i used but not sure how to on here
[Galaxy Note 4 Q&A, Help & Troubleshooting] nicholes:
my phone is dead completely right now , here in india i dont have any option (as sammy ask for 311 $ for motherboard)

and local repair shops also could not arrange any motherboard. and one or two of them who has some used motherboard they ask for 105 $ and they charge more for their service

The dead phone is absolutely useless for me. I will have to buy it from aliexpress even if it is a used one. then i will sell it, this is what comes in my mind.

EDIT: I asked them motherboard is used or new one but no one replied as yet,:( so i assume they have used one
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:

Hi

Put your phone in a plastic bag and put it in the freezer for about 10 minutes minus the battery. This is the only way I can get my faulty Note 4 to switch on when it dies. Once booted install the WakeLock app on it and put it in 'partial_wake_lock' which will prevent it from re-booting etc.

Of course it's not a permanent solution but it will get your phone up and running again.

Possible Solution

What firmware is it running ? You download Odin & Note 4 firmware and try this . You can go back to Amdroid 5.1.1 or get the Latest 6.0.1 firmware and go from there. Does your phone get Hot when it starts acting up ?
[Galaxy Note 4 Q&A, Help & Troubleshooting] nicholes:
well my phone was very hot like fire when i left it for charging for 3 hrs. since then i believe it is died.

however i will try fridge method.

[Galaxy Note 4 Q&A, Help & Troubleshooting] SimonSP:
My problems started while I was using 5.02 on the note4. It went completely unusable (reboots, could not turn on, massive lag when it finally turned on).

I then had to flash TWRP recovery and the stock 6.01 firmware. After that it still won't boot without pulling the battery. Using Wakelock now and no reboots/lag.

But I'm not happy about it - it's such a great phone and I would hate to part with it.

Still have 2 months warranty - but I fear that they might say that it's not repairable and try to push me to buy another phone (I want to keep my Note4). Anyone experienced something like this?

My Note 4 emmc brickbug test says write speed 130mb/s and it says no sane chip. But it also freeze and restart and now from two days it also stuck on boot loop. Don't know what to do should change the battery or should try custom roms. Any help will be greatly appreciated :)

Edit : After doing some internet search this means that my note 4 emmc is good. Also wake lock does'nt work for me
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Reboot your phone several times and see if you successfully boot every time - or if your phone:

a) boots into Download Mode.

b) Fails to boot

c) You see the red emmc message

Edit: I just ran the brickbug test.... It's saying that my Note 4 is fine - Which is Completely WRONG - I definitely have the emmc Failure - I'm just using SOD App to keep it awake.

Your chip read speed is 35.2mb/s which is emmc failure ... but mine chip got 130.something mb/s write speed so i get no emmc error. Good EMMC chip read speed is 122 to 130 mb/s ... so you need to motherboard replacement. Mine is exynos processor

[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Using the Microwave for half a second to "nuke" your Rooted device during the Warranty period will ensure that your device won't turn on - Thus preventing Samsung from knowing that you Rooted your phone and being able to get it repaired under your Warranty - lol ?

Hello,

Don't know why am a new user here, been on and off since my Nook Color mod times.

Anyway just got a Note 4 used from ebay with sales slip and a few months on MFG. warranty.

Worked most of the day, installing lastpass,a few other favorite apps I always used on my Note 2.

Later, I know I had left it on, also on the charger, but I had trouble getting it to boot. Later it started doing all the problems in this thread.

I received it in what looked like the owner had wiped and factory reset.

Thinking I had a buggy app I did the same, and problem still there with factory reset and no new apps.

I put it into safe mode, same emmc problems.

I contacted the ebayer, and he said it had worked perfectly and had gotten a new phone so is selling.

Like new in its box, all accessories, 2 batteries, etc.

Since in warranty I started to see if it was transferable and ran into the emmc problem posts here.

Questions:

1. Ebay listing says no returns, but it was sold as Used "works perfectly" etc. Do I have recourse to return it anyway?

The seller was nice, even tried my carrier with its imed, etc before shipping.

2. After reading most posts here, I am going to give up on Notes and look for the most recent brand with a replaceable battery. Any suggestions?

[Galaxy Note 4 Q&A, Help & Troubleshooting] Pari5ian:
Hi JH

If the phone is still under warranty you may be able to get it repaired that way, that's if it's a Samsung warranty?

With regards to eBay the phone was sold as working perfectly, but on receipt that turned out not to be the case so you're within your buyer rights to open a case and get it refunded. I managed that a few years ago with a Samsung that turned out to be fake, and got a full refund.

As you are still communicating with the Seller let them know that you're unhappy with the phone because it's not working and that you've now discovered that the Note 4 is notorious for having a motherboard failure and that you will be opening a case with eBay for a refund. Had it been advertised as 'faulty for parts, not working' the you wouldn't have had a leg to stand on but it wasn't. It's worth doing, as you're going to need that money to purchase your next non-Note phone.

Good luck and do report back and let us know how you get on.

I've been searching high and low for a non-hardware solution and I think I found one! Instead of using "Wake Lock - PowerManager", which is a great app but drains your battery like no tomorrow, use "CPU Awake". My phone is literally back to normal (without the battery drain!)

Sucks that I still need a software solution to fix a likely hardware problem, but this is so far the best working solution that I've found.
[Galaxy Note 4 Q&A, Help & Troubleshooting] logosA:
I ve been using it 6 months now, I have tried to suggest it to users with similar problems, but they dont seem to want to listen to that.

Any way, if you set it for unlimited time and also when phone start(or reboot) you dont need to ever worry about deep sleep 'death'. Also reducing notifications to minimum, you will never notice its even there.

You don't think that maybe dropping the phone & then hearing random parts rattling around inside might be the problem.... lol

And you thought that replacing the battery would help or preventing the phone from sleeping would change anything?

I'd suggest that if you want to keep it:

a) If you have the expertise - take it apart and find out what's rattling around inside & fix it.

b) Take it to a Repair Shop and get an estimate (they'll probably charge you for the estimate) and decide if you want to pay to have it repaired.

c) Get a new phone ?

[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Well good luck with your phone - Reboots etc can either be software related - ie: most common cause for Custom Roms is the Kernel - The main issue on this Thread is a Hardware fault in either the design or the parts supplied to Samsung which results in the emmc failing - Reboots and Freezing are a symptom of the problem - When you start to see red text on the screen after a Reboot or when your phone does not boot normally and goes into Download Mode - That's pretty much the telltale of the emmc Failure.
