Note 4 - New Update Experience 05 Sept 2017

Hi All,

Had another system up date show up today (N910FXXS1DQH3) for my note 4 - 910F - Like the last three updates was hopeful that they have fixed the problems.

Downloaded the update, turned off wake lock, phone switched off as part of the update procedure then wouldn't switch back on, Battery out for 10 mins then it switched back on and said the update had failed.

Tried again and this time it rebooted and looked to be updating ok, got to the end and switched off again as part of the update procedure. Battery out etc as wouldn't boot. When it did switch on it went to the rom download screen, battery out again!!!.

Tried again after 10 minutes and it booted to a pre boot error screen says failed mounts repeatedly etc in red. Battery out again

Tried again in 10 minutes and it switched on ok, Took 30 mins and its rebooting / switching off every few moments again.

Wake lock activated again and its usable. Thank god for wake lock.

Was looking to get a note 8, but as i cant sell this phone as it is wont be work have no deposit to put towards it , and i am not paying £50 plus a month for a 24 month phone contract.

Samsung you suck.

**UPDATE**UPDATE**UPDATE**

1. Contacted WOOT.COM again to see if they might ask the reseller if they had the unlock code on file.

2. No response.

3. I had contacted T-Mobile to see what plans they had.

4. Had one that I might have signed up for.

5. Thought I would give one of the on-line UNLOCK sites a chance, so I picked one and sent my $23.00.

6. They sent me a code that did not work.

7. Hmmmmmm. So I looked around the board and found a thread that mentioned the on-line code sites and 2 names came up.

8. I said "What the hell" and contacted one with the info from my phone, and what the msg said when I booted up with my TRACFONE SIM.

9. They said "YES WE CAN"!!!!!

10. O.K. $15.00 sent this time for the USB method (cheaper than the first!!!).

11. Had to send a few emails to get things on track and had the program up and running and got a "WE CANT UNLOCK. CONTACT US FOR A FIX" kind of msg.

12. Email again.

13. Email back said DL this file and follow the instructions and you will be golden.

14. Would not work!!!!!

15. Hmmmmmm Part of the method used ODIN.....

16. HMMMMMM Lets try a newer ODIN.

17. I had a number of ODIN files and I used the latest one I had.

18. That did the trick!!!!! Just like magic.... WAM... You are unlocked......

19. TRACFONE SIM in the phone and "Houston we have lift off!!!!!"

20. So far working like a champ with NO issues at all. In fact, I think the phone is working faster that before I sent it in!!!!

21. Emailed the $23.00 guy and said it did not work. No response. So I am working that issue through PayPal. Will see if I get my $23.00 back...

22. Bottom line is that my Note Edge is now up and working better than it ever did from the time I purchased it!!!!!

23. The $71.00 Samsung Repair Center was well worth it:)

If you are having trouble in powering on your Note 4 just put it in freezer for one minute don't forget to put it in the bag and try to power it on or you also can take out your battery and put it in front of AC at full power for 2 to 2 to 3 minute and try to start it hope this helps by the way what is developer option tweak here I'm using only wake lock
[Galaxy Note 4 Q&A, Help & Troubleshooting] alabamalower:
Freezer trick=hardware issue.

See if your country has an authorized Samsung Service Center and see how much to send it in. I did that in the USA and they replaced one of the main boards and a few other small items for $70.00 and change. So far after a few ds working GREAT!!!!!!

The 'developer options tweak' was something SpunkyMentioned: https://xdaforums.com/showpost.php?p=73414206&postcount=418

For me, I had to keep Wave Lock on, but it did stop the sudden lockups. Been running solid for a week. I can live without being able to fully shut down each day, vs. doing the remove battery, drain via power (or the freezer trick) and retry. But for those times when I do need to completely reboot this routine works for me. If I simply choose 'power off' I kind of get a brick. Until I remove the battery, wait a minute or two and do a long (minute long) press on power. Then I put the battery back in -- but I don't add the back cover and wait for 'mmc error' screen to pop up. The one with the 'Don't shut off' warning. Well, it seems the only way to restore from here is to immediately remove the battery and then put it right back in. Despite that warning, I found that this is the only way to get the unit to reboot again normally.

I keep the Wave Lock app on Autostart and in the 'Partial_Wake_Lock' (level 4). It's been running solid without any hitches for over a week like this.

A couple of other things about my system that may or may not effect how these 'fixes' stay fixed. I have also installed a small app called 'Install Apps On Sd Card Move' which is the only app I've found that seems to bypass the block on moving apps from Internal to External SD without having to Root a device. It works great. And because the whole mmc issue seems to be related to Internal SD corruption, it might have something to do with why it seemed to straighten out some minor things I was having with apps that I don't have any problems with on my other devices.

I also don't use my device as a phone. Sacrilege? Maybe. But I prefer to keep smart phones as pocket computers, not as phones. I have a very cheap, low powered (and tiny) old phone for texting and voice. So anyhow, no SIM card.

I bought my Note 4 used. I was moving up from a Note 3, which I really love too. I had considered buying a Note 5 but I just can't live without the external SD option (being in a low-options, semi-rural means I like to carry music, movies and books with me, and not on an unreachable or glitchy cloud connection). So I don't have SIM card in my unit. I don't think this should make any difference though.

Currently testing solution #3 - DFG solution. It took some time to get my Note 4 to do what is needed - freeze after the dummy file was generated. At the beginning, the DFG app would just crash, time and time again. After getting a couple of those freezes the phone started behaving normal. The memory write test shows values 4 times bigger than before DFG fix. It is stable now for 3 days, fingers crossed.

Just wondering... For those having trouble waking up Note 4 after it was powered down... There are several methods how to make it power on again - take the battery for more than 10 minutes, press and hold the power button for more than 30 seconds when the battery is out, put the phone/motherboard in freezer for up to 10 minutes, put the battery in freezer for a few minutes, ... Is there anything else that I didn't list here?

Well i am getting no EMMC error at all ... and i also got no bootloop issue ... wakelock worked perfectly fine for a month and now when i turn on wakelock it freezes and reboots more than usual ... so can't use the wakelock anymore ... also i have never tried any other rom

[Galaxy Note 4 Q&A, Help & Troubleshooting] BluePhnx:
My fault sorry!

Didn't know that you had the issue with emmc. So my post was irrelevant.

Man it sucks that you got it after 1 month. I would try to return it back.

You can try to contact Samsung for repair.

Or

Buy the motherboard on eBay and replace it yourself.

Did you buy it used or from a store?
[Galaxy Note 4 Q&A, Help & Troubleshooting] nicholes:
I got a used one.

And right now phone is working fine but I am afraid that it might dead. I got that Emmc read failed when I was trying to flash it but later it gone. I don't know what to do now
[Galaxy Note 4 Q&A, Help & Troubleshooting] BluePhnx:
Since you bought used might as well get your money's worth out of the phone. I had the emmc error since January and been running the wakelock app until now and the phone still runs. Hasn't died yet but saving money for a new phone until then.

You can try selling it for parts and see if what you can get.

Or as I said earlier try replacing the motherboard.

If you have the money or can get a good amount on the sale of the phone then look for another phone.

If not use it until it dies and in the mean time save up for another phone.
[Galaxy Note 4 Q&A, Help & Troubleshooting] robmeik:
Same here! The WakeLock app (setting 4 - partial_wake_lock) certainly seems to enable the phone to keep going without freezes and reboots and I've had no more "mmc_read fail" when rebooting! Keeping my fingers crossed till I can afford the Note 8! I may get a Note FE if the Note 4 fails completely before I have the funds for the Note 8 ... we shall see!
[Galaxy Note 4 Q&A, Help & Troubleshooting] Sp0oner:
I called the Samsung repair shop again as I thought the quote of £250 i'd been given previously might be better than risking one off ebay only to find they are now quoting £400 for the mainboard and a screen replacement lol. What a joke.

Anybody got a link to the mainboard as the one posted previously was out of stock when I looked? For £50 I might risk it and give it a go following the youtube video.

Bad news my phone died today :((I think so)

I Baugh a used one last month

Last time when I saw it alive it has 12 % battery life(on wakelock for last 20 days) so I put it on charger and I was using it while it goes up to 16 %.

I was planing to get 100% battery so keep it for 3 hrs almost (that I purposely once in a month)

So when I came back to my phone. What the hell it was hot like fire :crying:

I tried to unlock but no luck.

I immediately removed battery and put my phone and battery in front of the AC. (till then I realized it has no life)

I put it in fridge with little or no hope but no luck.

I have another battery which was 18 % charged when I removed it last 15 days back. But no luck

I measure curren(using multi meter) one which was in my phone and got fired is providing 3.79 v while other one is giving 3.93

One last thing I will try with little hope that I will charge battery using some external source and try again. Hope this info helps someone

I enjoyed the phone. The best performance.

But unfortunately Samsung.......
[Galaxy Note 4 Q&A, Help & Troubleshooting] BluePhnx:
Man that sucks!

Personally I think you got scammed from the person you bought the device from, he knew the phone had the emmc error and didn't mentioned it to you. That's why I'm weary about buying another note 4.

Wish you all the luck!
[Galaxy Note 4 Q&A, Help & Troubleshooting] nicholes:
Should I get changed motherboard in local market rather than Samsung? It will be a much cheaper deal in India I think.

Or

I should forget note 4?

Please suggest

Back to Lollipop?

I have got freezes and reboots with my N910F since N910FXXS1DQH3 update. The eMMC check tool says: sane chip.

Will flashing back to Android 5.1.1 work to restore normality? ;)
[Galaxy Note 4 Q&A, Help & Troubleshooting] hahn.lelo:
Unfortunately not ... you can try wakelock or try one of the other mentioned methods.

To get rid of the issue completely you need to replace the logic board. ...

[Galaxy Note 4 Q&A, Help & Troubleshooting] Mitdgart:
Note 4 issue solved in 99%

Hi Everyone.

I am new and not english native speaker so I apologize for any language mistakes.

So... My Note SM-N910F has started lagging and freezing and rebooting over a month ago. After 2 or 3 days has stuck on "downloading mode" screen and nothing could help, even keeping the battery out for a few hours. Then I have read most of your posts...

I own my Note 4 since the first day on the market and never ever had any issues with.

In meantime I have changed the battery for a new one, but it was not good one so I have got 4 of them.

After my device has stuck I have checked the voltage of the batteties with the voltage meter. And there were diffrencies, big ones I can say. From 3,78V to 4,18V. Then I have decided to go back to the original one. Unfortunately it works half day with a continues use but it works while I am at work so I am satisfied.

Changing the battery did not solve the issue, maybe partly only.

After a few days and tousand pages in the internet I have decided to open the device and exchange the charging part. Do not do that. I have seen a lot of tutorials how to do with explanation that solve the issue. It does not! If luckily you manage to start the system in your device any software/apps is only temp solution.

Here is mine:

- get the battety out, test it, needs to have 3,85V

- put the battery in after minimum 15 minutes

- start the device using hard resrt buttons combination

Vol Up + Home + Power

- wipe cache partition

- wipe data/factory reset

- reeboot the device

- go to download mode

- plug it in to PC with installed Odin and downloaded Recovery Rom and root your device.

- install Recovery Rom... and nothing else.

- reboot.

It might take a while before the sytem will start but in mine with a full success.

After that first I have done was format my SD card (64Gb) once more to Fat32 and install half (maybe 65%) amount of apps I had before. Watching and using my device I have noticed:

- do not over heat it, that cause issue

- do not install to many apps (possible data partition is damaged)

- do not use any other charger than original

- do not use fast charging (I know it is so usefull).

While I was doing all listed things after my device came back to life still happens some reeboots but without "downloading mode". Once I have stopped do all of that my Note works fine without any issues at all. And now it is 5 weeks after and still is fine.

I will try to find Odin version and Recovery rom which I have used and post it in here.

Hope that helps at least for some of you.

The emmc Failure will eventually become terminal for your device - The Freezer trick will also eventually fail to get the phone to boot - It's a Hardware problem due to the fact that it's a Hardware Design and Parts fault - The battery is not the problem.

[Galaxy Note 4 Q&A, Help & Troubleshooting] Mitdgart:
The battery may not be a problem but the fact is when I use even brand new one but with higher voltage reading, the issue is back (it is from my observation using my device only). Also higher voltage battery heats up much faster.

I agree that is hardware issue and I will say it is the memory part cause the problem. Anyway all that steps have solved the issue with my devicde and for the last 5 weeks is nothing wrong at all.

Hope it will stay like that. I will keep posting if anything change. If not I will post after a while to let you know.

Hello everyone

i had a problem like the one that was mentioned in most of comments

but my problem start with updating my n910C To MM

i noticed that sometimes device freezes and ask for backup password no fingerprint ( same screen you get after rebooting )

but what is happened that it is not a full reboot ! as when i enter the backup pass i can see last opened app stilll work in the same window ! and i don't the reason till now ..

this issue and full restart issue occurs slightly and i have no problem with that

full restart issue ends with replacing battery

BUT

my largest problem now , i have just bought 64 GB micro SD card , after attaching it i can notice that there is a general lag and wake up lag in my n4! , when i un-mount it everything works fine ,

after searching i found that problem lies in exfat file system of 64 GB , and somehow there is a conflict between it and n4 kernel

solution is whether to format sd with fat32 or flash custom kernel that would solve problem of lag ,

i tried formatting my sd with fat32 , replacing it with another brand still the same

does anyone knows the solution?

I took my phone to Samsung and they wanted to charge me $66 AU to send it away without even looking at it. They said that as the phone is over two years old I would have to pay.

I told them there was no way I am going to pay when it is a design fault (or planned obsolescence).

I've emailed Samsung support again to see what they have to say.

Up to now the phone works great and with a custom rom & the bloat removed I could have kept using it for years, just replace the batteries when they die. Really not happy and don't want to downgrade to a new phone without a removable battery.
[Galaxy Note 4 Q&A, Help & Troubleshooting] nicholes:
I went to Samsung they asked me 311$ (20000 INR)..

ridiculous ,

I have given my phone to a local repair center they told me that they will try to repair motherboard and advice me to sell note 4 as they are facing reboot lag freeze now a days and phones are dying so sell it and see another phone. He told me even if i bought a new motherboard it will die after or within 2 years.
[Galaxy Note 4 Q&A, Help & Troubleshooting] o0o.paw:
I have a question for anyone that is having this problem.....

When you take the back battery cover off does your battery fall out?

We have two note 4's in our family and one has the reboot issue and the other doesn't.

The one that is working fine you take the battery cover off and the battery will stay in place.

The one that has the freeze/reboot issue as soon as you take the battery cover off the battery drops out.

I was wondering if there is an issue with the connection with the battery and it is causing power

fluctuations?

I'm currently running an experiment. I've ran some electrical insulation tape along the bottom edge of the battery to ensure a tighter fit of the battery.

So far I have used a stock rom for about half an our without any freezes or restarts. The keyboard opens up straight away (before it could take 20 seconds to open).

I've now re flashed my favorite rom and am going about my normal de-bloating / installing my favorite apps / adding some stock Samsung apps not in the rom / adjusting the settings on Kernel Auditor / Setting up my email and google play log in etc / restoring all my 17000 text messages. I'm only part way through doing all this but no lock ups either ???

Surely it couldn't be that simple?

Could anyone having this issue please let me know if the battery appears a bit loose or falls out?

I'll post on here sometime tomorrow to add if the freeze / reboot issue returns.
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
If the battery is falling out of one device - You may want to place the battery on a glass table (or similar) to make sure that the battery is flat and not swollen - If the battery is swollen that means that it should be replaced.

[Galaxy Note 4 Q&A, Help & Troubleshooting] o0o.paw:
I've had that happen to two batteries so far. You notice the power going from say 70% to 10% really quickly. Yeh they swell up and that's when you know to get another one :)

This is not what is happening here.

They all fit fine in the other note 4 but not in the one that is having the freeze/reboot issues, there is just a slight looseness to the battery. I have three batteries. I've already got a low battery warning on one so I've put another battery in (with the insulation tape added too).

I'm still going through my install / debloat stage. The phone did reboot twice due to me selecting the wrong Governer in Kernel Auditor but that has happened on the other phone too when I set it up. I did have a couple of lags about a minute after the phone booted too but I have Kernel Auditor delayed for 50 seconds before it applies the settings so I think it was doing that.Other than that It's updated all my apps through the play store installed about 15 apps updated all my Xposed settings and apps without lags or freezes or unintentional reboots.

I have to grab some zzzzz's. Hopefully the phone doesn't die on me overnight as I need the alarm to wake me up in the morning.
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Yeah I wouldn't put too much on what a local repair shop says - It's a luck of the draw with the motherboard... If every Note 4 was having the motherboard failure - You could bet that Samsung would have been FORCED to address the issue!

It's really up to you to decide what you want to do - The Note 4 was the LAST Samsung device that had BOTH the removable battery and the external sd card... Wonder how much it's going to cost for people who have to take their phone in to get the battery replaced on the new devices..Cell phones are pretty much viewed as disposable items now.
