Hello all. I'm here today seeking help with a problem I've been having with my note 4. A few weeks ago, the phone randomly started lagging really bad, reboots by itself and sometime fails to boot giving the "mmc read error". Usually requires several battery pulls to get it working again. Had this problem during 5.1.1, upgrading to 6.0.1 has done nothing. I have tried booting in to safe mode, clearing cache partition and a factory reset, all in vain. Phone is stock and clean, called Samsung and was politely told to "go f*** myself" since the 1 year warranty is over. Phone is Canadian. Thanks to all those who can help.
Hello - I've just had this very same error in the past 2 weeks and only fixed it today.
MAKE SURE YOU BACK EVERYTHING UP ASAP - NO EXCUSES.
Its a hardware failure I'm afraid.
I had to take my phone into the Samsung service centre today, and they replaced the motherobard after they confirmed it as dead.
My phone has the exact same symptoms as yours (lag, reboots, booting only into download mode), except that mine eventually refused entirely to turn on. Im not joking; the next time that it does turn on, make ure you do a phone and SD card full back up before you lose everything (pictures and such like).
I dont know about you, or where you are located, but my Note 4 has a 2 year warranty (Im in the UK) and I received it a year last March ago. Still well within warranty.
Alternatively, you could have a look on ebay for a new motherboard and replace it yourself.
Good luck!
I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
I didn't see an explanation of the purpose of the pit process ; could someone explain?
I am very familiar with custom roms and kernels, Pit is new to me..
Thanks

Hi Wilson,
welcome to the club, I am having the exact same problem now.
And bad news first, nothing will help you/us except a change of the motherboard... So bring it to a Samsung service center, the only thing you could do.
Believe me, I tried everything there is to try, including full wiping with flashing PIT files, etc. etc.
Forget it!
This is a hardware issue, as the mmc's are faulty and die after a year. Great.
Just to inform you, a pit file contains the infos about the partitions on the phone, their sizes, file system, etc.
So if you somehow compromised the structure or filesystem of the partitions, you could revert them back to the stock format.
Yeah, but doesn't help if your flash memory is corrupt on hw level...
II don't want to be an alarmist but back on 17th June 2016 I created this thread DM Verification failure , Please flash ENG binary then install DNK
At the time I wasn't sure what had caused the problem but last night with a different phone I used KingoRoot and it corrupted a second phone of mine. Now two out of three of my Verizon Note 4's have the dm-verification-failure.
The symptoms of the problem are when I am navigating some of the swipes lag. Sometimes when typing there is a lag delay before it is entered. Sometimes Wifi lags before it is turned on and the phone forgets my wifi password.
I found this thread How to solve dm-verity verification failed/need to check drk first on samsung devices but I don't have the experience to do it. Can a developer create the fix for the Verizon Note 4 , PLEASE, Thanks

I am at the end of consolidating all the info I can to determine if I should get a Note 4. Root is the thing that matters to me, but I have learned that regardless of 4.4.4 or 5.1.1 you have to unlock the bootloader which is the challenge.
Just as I think I have it all together and that the methods provided (on XDA only) are the only only ones available and apparently stable, I read this.
Am I COMPLETELY MISUNDERSTANDING your post? Is your post from here http://forum.xda-developers.com/not...bilized-process-to-unlock-bootloader-t3375527 which I've saved as reference for rooting a device no longer accurate?
I'm overwhelmed from so much research and think I've curated the posts that matter, then I see this. Can you offer anything on this? Again, I may not be understanding. I am NOT a developer or programmer. I've rooted a few devices, but it has been a long time with the most recent not requiring the seeming complication of this one (thanks a lot, Verizon!).

The stabilized-process-to-unlock-bootloader I posted is still valid. I recommended using Kingroot. I found the dm-verity problem with KingORoot. We need more feedback to be sure. I never had the problem with Kingroot. I removed the link to KingORoot from my guide today.

Hmmm..ok..thanks for the reply.
That's interesting as I've read so many posts that say KingRoot is not the way to go but rather KingOroot is the correct on to use. Specifically, a lot of people seemed to have tried it unsuccessfully in the process.
I was also hoping to avoid KR as I've read it is a bit sketchy. I've used it twice before doing that and found a Nextbook tablet it worked great on with seemingly no apparent problems since. Another Samsung phone was rooted with it (I was actually searching for KOR, but didn't remember the name exactly and ended up with KR on a search). Unfortunately, the security pop-up keeps coming up trying to remove it. The user who didn't know what they were doing inadvertently gave it the OK to remove it, and now I haven't been able to re-root with it...arrggh..
I recently thought to install their Purify app (which they push when doing KingRoot) separately, but the permissions in the app say that you give it the ability to analyze the content on the screen in an window...I can't figure how THAT is needed to block startup programs or background one to save battery!
So, I was hoping this meant the KOR was good to go with the process after the bootloader is unlocked and stable per your post. I wonder if anyone else is running into problems. I know this is all very new still.
I don't suppose you could tell me:
1) Is permaroot available (with these new methods) only on 5.1.1 , or is it also available on 4.4.4 ? I haven't been able to decipher that.
I kind of prefer KitKat over the material design changes that are just wasting space on my screen in JellyBean. The Note 4 I got to purchased recently (unfortunately, it was a sketchy phone now being returned), had notifications on constant screen overflow because they waste SO MUCH SPACE with them and with unnecessary notifications that I cannot stop from showing (Power Saving, Wif connected, Blocking on). I know a good bit of that is Samsung, but the non-compact use of the notifications is Android ( Google's changes). It was better on my SG3 with 4.4.4 even though they still has persistent notifications.
I'm hoping to root and find a mod to stop showing those. I'm aware enough to check my connections via the settings when needed.
Thanks Again.

I can only report my findings. We need more feedback.
The only real negative I've noticed with KingRoot is that it's erased the serial numbers from both of the phones I've used it on. Thankfully it didn't affect the IMEI, but whenever I try to check the serial number on those two devices, it just shows a bunch of zeros. Back up your EFS partition first (if you can without being rooted, I'm not sure), or at least make a note of the serial number. You can manually edit /efs/FactoryApp/serial_no to restore your serial number as long as you know what it is. I don't believe the serial number is used for anything (except maybe warranty-related things), just annoys me that KingRoot erased it.
As far as removing KingRoot, after you unlock the bootloader you can flash a modified stock firmware file for the phone (one that has had aboot.mbn removed) and still retain an unlocked bootloader. Flashing anything with an aboot.mbn will re-lock your bootloader, so be sure you remove that from any Odin tars before flashing. I had access to the full factory firmware for the device (containing the PIT file and a couple of other partitions not found in the home firmware files hosted by sites like SamMobile) so I stripped aboot.mbn from it and flashed that to make sure I started with a clean, KingRoot free device.

Thanks, I like the way you think.
Is there some file I can take from a good working Note 4 and repair the DM verification issue ? Do you think I could do it with efs Profestional. Just wondering.
I initially used KingRoot, and it failed 20 out of 20 times to root my phone. I used KingOroot on my laptop (in a VM) and it rooted my phone first try. I don't have any Wifi issues and I don't see any "DM Verity" messages anywhere on my phone.

I think, You would only see the DM Verity" messages when you are in stock recovery. Once you log into your google account, it remembers your passwords. But on my phoneS, I still get the other lagging problems. What ROM are you on?

Same here, only I used the Kingoroot APK, no issues on either the retail or DE. On JasmineROM (6.0 on the DE and 7.0 on the retail)

The lag is most apparent on stock rom that I rooted with KingOroot apk. On CyanogenMod it is more like a hesitation. The damage is so far as I know irreversible.
The other phone that has only been rooted with KingRoot is a a factory DE it does not have the DM Verification issue and it runs as smooth as silk on every ROM I have tried. So I say the problemS came from KingOroot. But we need more data points/ feedback to be sure.

Verizon Note 4 does not list serial number on the box, unfortunately.
Can you post a short video detailing the issues and is there something I can do to immediately verify if there is a dm verification problem with my device? I also used Kingoroot on my Note 4 due to KingRoot not working after several tries, but I don't notice anything out of the ordinary, just the usual ocassional lag that is on every Android device.
Only noticeable issues I've experienced have been the "Unauthorized Actions Detected" issue and Wifi passwords not saving using PaulPizz 6.0.1/OscarKernel, but that was corrected with the freezing of a couple Samsung security apps and a build.prop edit.

I'm working this now FIx DRK/dm-verity, Factory CSC and Serial Number So far I have been able to restore my serial#. after I turned on the hidden menu.You have to be in stock recovery to see the dm-verity verification failed message. You would have to Odin back to stock to see it.
Lag is not normal unless you have a ton of apps running. ., Wifi passwords not saving is not normal not even once , I bet you got the bug.
Maybe, but I don't have the wifi passwords issue unless I flash OacarKernel over either Jasmine or Paulpizz, stock kernels are OK in that regard.
How bad of a lag are we talking about? Slight hesitation or full on freezes for more than a second at a time?
After a few weeks of using the device with custom ROMs, no lag spikes have been out of the ordinary for me, feels more responsive than my Note 3 and noticeably better than both the Nexus 6/Moto X I've previously used.
The only truly frustrating lag spikes I've noticed are trying to use this site without any form of adblock on Chrome.

The Best example is scrolling lagging on this site with Chrome. My phone without the issue is as smooth as silk. No hesitation. The phones with the bug maybe two swipes work then the third swipe lags then the page jumps to catch up. It is uncomfortable to use.
XDA forums have been fine for me in Chrome since I installed an ad blocker not too long ago. Before that I would get annoying pauses and skips, like you're talking about. Though this also happened on my Note 3/Moto X/Nexus 6 as well on this site.
Is there any way to see if any running processes have large latency spikes when these lags/pauses occur?
Also is there another kernel I can try on PP 6.0.1 ROM or a way to easily flash the stock kernel on it without restoring a backup? Seems like the minor issue with Wifi only crops up with OscarKernel.

Verizon devices do not have the typical Samsung serial number. The only serial number your device uses in the last 32 bits of your eMMC CID. The EFS serial number is supposed to be 00000000, and will not affect any functionality of your device. You had your DRK (Device Root Key) erased. It could have been from damage to the EFS partition or something else benign. You'll want to flash complete stock Odin, reboot to recovery and wipe data, and reboot. This should fix your issue, but if it doesn't, let me know and we'll cross that bridge.
In response to OscarKernel not saving WiFi passwords, it's an issue related to ROMs and not my kernel. It does not use secure_storage, so setting ro.secure_storage=false is necessary, and once done, everything will go back to normal and save fine.

The tutorial I was following was for the SM-N910C not the SM-N910V . For that device, magix01 has a tutorial to fix DRK. I was working on the premise that if I could repair the serial number, I could then use emergency software recovery. Thanks for straightening me out about the serial number. Put that aside for now.
I did Odin N910VVRU2BPA1_N910VVZW2BPA1_N910VVRU2BPA1_HOME.tar several times downloaded directly from SamMobile and did the data wipe and rebooted every way possible I think. I still get the dm-verity failure and more importantly, It still has the lag bug. I have in my possession another SM-N910V that does not have any issues. I was wondering if I could take a file from the good phone and use it to fix the defective phone. Thanks, for your help, I am ready to cross that bridge.
I'm completely at a loss at this point.
I attempted to root my Samsung S7 (AT&T) with Odin, and received an error. This is my first time ever rooting a phone, and I am generally oblivious to this kind of stuff. I disconnected the phone, and it began bootloop. I loaded it into download mode, and attempted to reset to stock. However, I have had endless issues trying to flash the stock firmware to my phone. At one point I unplugged the device once again, and I received the "use Emergency Restore" error screen. I tried to restore with Smart Switch, but I was not able to access my S/N (box is nowhere to be found, managed to find a S/N on Samsung's website since I registered it but Smart Switch wouldn't take it). So, I figured trying to restore with Odin was my last option. I have tried at least 3 different Odin versions, both modified and not, and not a single one of them has worked. I've received Complete(write) errors, Model Dispatch Fail errors, and Re-Partition errors. I've tried about 3 different firmware files as well, and while I think the one I have right now is most recent, none of them seem to be working. I thought maybe an issue I was encountering was that USB debugging or whatever it's called was disabled, but I have no way of telling because I cannot boot my phone.
I was fiddling around with all of this from 11pm to 6am last night, and picked it back up as soon as I woke up. I've been freaking out about this for hours.
I feel like I'm running in circles here. I don't understand what I'm doing wrong. I'm recovery bootlooped as well. The only thing I can boot is download mode.
I wasn't very cautious with this process, and I am completely unfamiliar with most lingo on these forums and the whole process in general. I really regret trying to do this. So -- is there anything else I can try to do to fix it? Or is my phone bricked for good??? I'm endlessly frustrated and have honestly felt like crying a few times over this. I shouldn't have messed with something I know nothing about. :crying:
I thank you for your patience in dealing with me as a beginner + appreciate any help you're able to give.
Cheers.

If you can at least get into download mode, then simply flash it with the latest STOCK firmware for your particular model.
That will bring it back to life, and you can attempt rooting it again, if you dare

Did you finally recover your phone? I'm in the same problem here since yesterday and feel your frustration right now. My phone is a Samsung S7 model SM-G930A from AT&T.
I found this thread https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039 and I following the "Return to stock part", now downloading the firmware. Hope it helps.
I'm stucked in the blue screen "An error ocurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". Of course I try the Smart Switch but says that my model is not supported!
How can you recovered the download mode? I press the on/off button for some seconds and the screen turn of, but it turn on again with the freaking blue screen "An error ocurred while updating the device software. ...". I tried all the possible button combinations.
Thanks and good luck.
Stock firmware
Make sure when you go into download mode and flash that plugging the phone in is the LAST thing you do. I.e. plug phone in only after it is in download mode and only after you open Odin. Secondly, make sure you flash the STOCK firmware, as in Android Marshmallow v6.0.1 . Additonally, make sure that the re-partition option is NOT ticked, and also you might want to try turning off auto-reboot, and just hold the power button after unplugging once the status bar is all the way full and Odin says complete. Also, you need to make absolutely sure that you're getting the firmware for your exact device. I.e. SM-G930A stock firmware is NOT compatible with SM-G930F models. You could also try reinstalling the Samsung drivers. I just flashed to stock firmware then updated back to Nougat yesterday, mostly without a hitch by following these guidelines. There is a download page on rootmygalaxy with all the stock firmwares, that's what I used (I'd link but I just registered here). There is a very helpful guide on droidviews about how to update to Nougat 7.0 once you have finished flashing the stock firmware.
If I were you, I would just avoid rooting altogether. Rooting for me caused very bad performance and battery life, and it wasn't really worth the trouble. Sure, getting in-app-purchases for free was nice but I never tried flashing a custom ROM or anything because most of the stories I read involved soft bricks, bootloops, etc.
Hopefully not having USB Debugging and OEM unlock ticked doesn't brick your phone, I'm doubtful that it will. For the poster above me, make sure your phone is all the way off, the download mode button combo is vol. down+power+home all at the same time, and hold them. A screen should pop up saying press vol. up to continue. If you're still having problems, I regret to say that I am also relatively new to this and I am not all that knowledgeable.
I just made a post about my unrooting process, hopefully it helps!
