Use this app to check for the emmc brickbug so you'll know.
A lot of non brickbug Note 4s do the early shutoff thing when the battery wears out. I'm not sure about the picture over text thing tho.
https://play.google.com/store/apps/details?id=net.vinagre.android.emmc_check Download this app on the phone and it will tell you if the phone has the emmc bug. If you do, I don't know if it will be worth it to you to have the motherboard replaced. Being a Verizon phone you won't have many options for a replacement as most unlocked phones that aren't specifically made for Verizon won't work on it. You could always go to Swappa and look for good condition used phones for a replacement, you'll probably pay as much for a decent used phone as you would to replace the motherboard anyway.
Pretty much: "This is for users with 15' Samsung eMMC's not users with 11' Toshiba eMMC's. You can check this be reading the
/sys/block/mmcblck0/device/cid"
I just used this app to check my CID
A number of samsung handsets shipped with faulty eMMC chips in 2012, causing "sudden death" failure. This app will tell you if you're affected: https://play.google.com/store/apps/details?id=net.vinagre.android.emmc_check You can read more about it here: http://forum.xda-developers.com/galaxy-s3/general/ultimate-gs3-sudden-death-thread-t1993044. iirc it has been firmware patched since before KitKat
First, the app didn't detect the error, It just detected if your smartphone had the chip prone to die (by looking at the serial most likely). Second, as I've said before, the app wasn't meant to work on the note 4

It explicitly said the models it work.
Remembered it wrong: eMMC not MMR
Judging from posts of other users i would say that Note2-Note4 devices are affected. Worst case: your device will be bricked. Best case: your device will suddenly shutdown while it is sleeping (removing battery or holding power on button for >10 sec is necessary to start it again.).
- This app checks if your device has a flawed chip: eMMC Brickbug Check
- Running this app in mode PARTIAL_WAKE_LOCK "fixed" my note 2: Wakelock Detektor [Root]
From my understanding, the cause of SDS is a faulty eMMC chip on the mainboard (this app supposedly tests if your device has the faulty chip). I'm assuming when you return the phone for a fix, they'll replace the board with a new(er)/refurbished one that doesn't have the bad chip. I don't think it's that expensive, considering I paid $50 for the board to replace it myself.
How does it deal with the crazyrom issue? https://play.google.com/store/apps/details?id=net.vinagre.android.emmc_check&hl=en
Hey so I'm guy the who put this guide together.
To check the CID you would download this app to the phone and open it. If the CID listed starts with 15 you're good to go. What your checking here is to make sure you have the correct flash memory chip that is exploitable by this root method. If your CID doesn't start with 15 you most likely can not root the device no matter what you do. After your root the device the CID will still start with 15 as this doesn't change.
If you boot up the note 4 and it's on 5.1.1 it won't auto-install the update. It may prompt you to update but you can deny it by clicking cancel.
There are methods to root 6.0.1 but I haven't tried them so I don't know how reliable it is or how difficult it would be.
You can upgrade to 6.0.1 and keep your root. Though again i don't have experience with this but there are plenty of threads on XDA
One thing that people get caught up on and I admit it is kinda confusing is the difference between a Retail Note 4 and a Developer Edition Note 4. They are physically the same (hardware wise). Developer Editions just have an unlocked bootloader.
Once you unlock the bootloader on your retail note 4 you can flash new recovery software like TWRP. The recovery software allows you to flash new/custom roms. If you flash a stock rom you can usually flash an update ontop of it from within recovery modifying the rom to enable root. If it's a custom rom like cyanogenmod it may already have root access.
The different model numbers are the different carriers. SM-N910V is the Verizon Note 4, SM-N910T is the T-Mobile Note 4. Etc.
I'm at work so if I lost you anywhere or you have additional questions just ask away and I'll respond later tonight when I get out.
How is the crazy rom problem? I mean the EMMC failure https://play.google.com/store/apps/details?id=net.vinagre.android.emmc_check&hl=en
That XDA link points out that you need to have the Samsung eMMC.
Use this app to check the CID.

There's an app that will tell you if you have a bad eMMC.
Use this to check for the notorious emmc "brickbug".

Promptly return phone if detected.
Not sure why your link has the language override in it, but here's the fixed link for those who can't read Spanish.
Honestly that's what fucked up my phone to begin with. There's no KDZ for the AT&T variant and when trying to flash one it completely bricked my phone. No download mode, no recovery, nothing. I would go with the system.img route. Just PLEASE find the correct variant, mine was 10o and the root tutorial gave a 10g variant. You can find your software version on the back of the phone behind the battery.
I was going to go with a Note 4 but AT&T stopped offering it and the Note 5 has no removable battery & is still not rooted. And I'm not too fond of the way Samsung has an eMMC bug that causes 'Sudden Death Syndrome' that corrupts the phone and literally kills the eMMC. There's even an app that checks for the bug on the Samsung variant phones and a couple of threads that talk about it killing their devices.
The V10 isn't rooted yet so I couldn't go with that. The G4 is good but I think it was a lot of the apps they force on your phone that need to be disabled/removed to speed up the device.
I hate upgrading. It takes a lot of work to get everything exactly how I want it - especially on computers (that's why I only use the LTS Ubuntu derivatives). I guess if the eMMC fails (which I haven't heard about before), I'll just transfer everything to another SGH-1747. My phone has worked perfectly for a year or two (can't remember when I bought it).
... is the eMMC failure the bug in 2012 that has been fixed by now? 1 , 2 **
On the other hand ... maybe I should run the check for the brickbug
Or are you just talking about the normal wear on any sort of flash RAM over time?
P.S. Thanks for your comment.
