Firmware update, EQC1? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I don't see EQC1 on sammobile, anyone else see the 127 MB update?
I'm on EQB1.

Yup, I see it, 127.53mb on both of mine SM-N910T3 and
SM-N910T

I have it as well. Have you flashed yet?

I have it too. I'm not sure I want to flash, especially if it patches the ability to root my phone.
My phone also suffers from the SD card / reboot issue (the phone constantly boot loops when both an SD card and SIM card are in the phone). I wonder if this update will fix that?

I tried flashing it and it failed, I'm running a stock highly modified rom. I'll try reflashing the original stock unmodified rom when I get a chance tomorrow and apply the update. It looks like it's just security updates

Says "Various system improvements" for the QC1 update.
https://support.t-mobile.com/docs/DOC-28899

I updated to this version the other day, now I'm looking to root. Anyone know if the old root method still works? I may try myself in the next few days myself and find out.

I upgraded to it yesterday. Took about 30 minutes from start of install to finish. It updates the security to March 2017, has the new Google Play Store. Other than that I do not notice any other differences

Can i root after upgrade?

Does anyone know if this fixes the mmc_read failed issue along with its constant lagging/freezing problem?

I'm pretty sure the mmc_read failure issue is failing hardware and no firmware release can fix this. My understanding is some Note4's had dodgy flash memory and will eventually fail. I had this happen to my note4 last year and got it changed out under warranty at a tmobile store. My phone had the constant lagging/freezing for about a month before it would just no longer boot, it wouldn't do anything other than a quick vibrate on power up, no boot screen of any type.
If you are getting mmc_read I would suggest you get the phone replaced ASAP, and make backups of everything you have on it that you want to keep. At some point it probably just wont power back on again. Hopefully you are still under a warranty and can get it swapped out.

Hi,
That's certainly is one possible scenario (hardware failing). But based on my extensive research too, many have said that this could be faulty firmware. I went to a Samsung Experience Center and talked with a guy there and he said that it's a known issue affecting many Galaxy Note 4 Sprint users a few months ago. Samsung in the end replaced/repaired the affected units free of charge.
In the past 2 months or so, more and more Galaxy Note 4 users started experiencing this issue. And so it could be that the firmware triggered the issue, and eventually damaged the hardware.
Since we don't really have a 100% certain answer (of course, Samsung will never tell us), I'm just trying to see if anyone has updated the phone to the latest firmware and could tell us if it fixed the issue.

Try this https://forum.xda-developers.com/no...rom-n910t3uvu3eqc1-stock-rooted-odex-t3592242

I can't seem to get TWRP to work on this. I've tried several times with Odin, it appears to be successful, phone reboots, but then when I try to reboot into recovery there's no TWRP, only stock. Anyone else have this issue or any suggestions?
Edit: Tried something I remembered reading in another thread. I pulled the battery immediately after Odin successfully finished and the booted directly into recovery. It worked. I'm flashing pvsgh's rooted EQC1 and will report back if TWRP sticks
Edit 2: Success. Seems like pulling the battery after Odin/TWRP before the phone reboots did the trick

ok, thanks for the suggestion.

Anybody have a link for the firmware?

Can I autoroot with EQC1?

I tried auto root and got
RECORVERY IS NOT SEANDROID ENFORCING,
AM I screwed? I assume there's some way to get back to EQC1 and boot the phone. There has to be. But could I do it and keep the data. I was trying to get deleted photos back.

[Q] Internal/External (SD) Storage No Longer Working

Hi,
I have lost the ability to use my internal and external storage memory. Is there anyone that can tell me how to fix this. I am at a loss.
Thanks
Zack Cadieux
I have the same problem after flashing JPH firmware. (I know how to flash FW, I've been flashing every FW as it was released)
It says that there is an I/O error in mmcblk0p1.
I think i'm screwed as well.
Not one person knows what is going on
Hi,
Im supprised that even the dev's know nothing about this issue. I have read almost every thread and nothing to show how to respolve this issue. Is there anyone???
I had the same problem. I have a Bell Vibrant which I flashed to JPH using the Kies method, rooted, then One Click Lag Fix. Things worked for about a day then I lost my storage. Luckily I did the samsung 3 button fix first.
I downloaded the Tmobile Stock Rom, and used the following instructions to flash.
http://forum.xda-developers.com/showthread.php?t=734475
It booted up to the Tmobile Rom, and everything worked. I then used Odin to flash back to JPH.. rooted.. and now am contemplating the Lag Fix.
Not sure if it was related to the problem but I had my phone connected to my computer transferring files before all hell broke loose. I may have yanked the USB without unmounting... Just a thought.
Good Luck..

My situation is about the same. I did the update and applied the root and lag fix. Phone worked fine for a day or so and then it just locked up and couldn't detect the sd cards anymore. I rebooted and it was stuck on the S for over 30 minutes...I flashed HJ2 and when it rebooted all that happens is I get a gray blinking battery if it's attached via USB and if on battery it boots up to the I9000 initial screen and shuts down. Lucky for me the shop will do a swap when they restock in about a week. Back to the HTC for now.

Dont recall if I did any of the Recovery options, but I remember the big Grey Battery... You could even try flashing back to JPH through Odin... It may wake it up. But good to hear they will replace it, at least you have something to fall back on.

[Q] Optimus black stuck on firmware update screen

The story so far...
Bought a new Optimus Black and gave it to my girlfriend for her birthday a couple of days ago. After playing with it for about an hour she put it down, I picked it up and decided to have a tinker. I installed Cyanogen mod 3.5.1 after rooting it with Gingerbreak. So far so good but I didn't really like the look of the ROM and the absence of a Market seemed like hassle so I used ClockworkMod to restore the backed up stock ROM.
It's still working fine but now I see there is an official update from inside the phone. I presume it's the upgrade to Android 2.3 so run it and reboot the phone. That's when it all goes wrong. I'm now stuck in the CWM recovery screen. I try all the options, following any online guides I can find that were supposed to have worked for people. I try restoring the backup, restoring cyanogen, clearing the cache, dalvik, everything but nothing happens and I keep booting back into the CWM recovery screen.
Next day I try the LGUnitedMobileDriver and the phone recovery option but despite trying several times I can get no further. A friend tried to use Odin to restore it but got no success. Finally, we tried restoring with a KDZ file with
KDZ_FW_UPD_EN, Windows Enabler and LG B2CTool and now the phone got stuck in yet another loop - a black screen with 'updating firmware'. The LEDs flash for a minute and it reboots and does the same again.
What's more, the phone will now no longer charge or turn on without being connected to the mains.
What are my options here?
Follow the tutorial given below.

have you tried the CS_EMERGENCY option in R&D TOOLS? Wait I'll find the link..
Here >>> http://forum.xda-developers.com/showpost.php?p=18841596&postcount=8
http://forum.xda-developers.com/showpost.php?p=18740082&postcount=45
The CS_EMERGENCY is the only thing worked, he used a german V10A ROM. If you managed to unbrick it, you can flash it again with your desired KDZ, or use CS_EMERGENCY and flash directly your desired KDZ. TRIAL AND ERROR.
Emergency c-section... nope, I will try that now!
Said that it will get stuck at 4% but it is still flashing. Just wait for the phone to reboot by itself.
It just crashes with a fatal error as soon as it gets to the second tab (downloading) on both PCs I tried it on. I tried several KDZ files with the same result.
Does anyone know if it's possible to physically change the ROM on this phone and if it would be worth trying that before binning the thing?

Does it have warranty? Why not RMA it, I think it has a hardware problem now since you mentioned it doesn't charge anymore. Also, have you tried a different USB cable?
The warranty gets voided as soon as you root or mod a phone and it's probably as expensive to get it fixed outside of warranty as to buy a new one.

Most of the time they change the board right away if it can't boot (as many as I've read) board was changed and none just revived the OS. So they won't know you rooted it. Just specify that they should contact you first before making any changes.

true.. you can just tell them that you received an update and upon getting it the phone wont boot anymore.. just dont tell them that you rooted it or tinkered it in any way.. i'm sure you'll be able to get your warranty that way..

T mobile note 4 restart, and power issues

I have had my Sm-N910T for about a year now. When I first got it I rooted it without thinking it through. I used Odin and flashed cf autoroot. I unrooted it when it started giving me issues. Then it would restart, freeze, etc. I now have an app called wakelock and it prevents my phone from turning off. It works great it has the original firmware that installed through Samsung kies but when I try to restart it just shuts down. When I power off I can't always power back on right away. I have to pull the battery and hold the power button for 1 minutes release, then put the battery back in and it works again. I have put the original firmware and it is not rooted anymore. Is there any way I can fix this issue? So basically it works fine but if I turn it off I have to pull the battery to be able to turn it back on. Every once and awhile it'll go into download mode on its own too.

sounds like the same software issue I had. Idk what happened but the internal memory failed on my note 4. Have you experienced constant freeze ups? also have you gone into download mode with an error that says "mmc_failed can't boot"? It was something along the lines of that.

I updated it ota then on Samsung kies with the latest firmware. Everything works fine except the power off issues.
I think this is a common 5.0.1 issue, same thing started happening to me after update. Gotta wait for update or back to 4.4.4.

I would recommend downloading the full DOK2 firmware. You can find it in the below linked thread. Make sure you use the newest version of ODIN to flash it 3.10.7.
It should give the phone aq complete clean install of the firmware. Kies sometimes can be janky. It you are going to get rid of the phone the best is to do a full ODIN flash.

I had this problem too except it got really really laggy and would constantly reboot anytime I tried to do anything. Best I could figure out was it was a problem with the internal sd. Called TMO tech support, told them I did factory reset, tried it without the sd card, blah blah blah. I said it's a hardware issue that is beyond my control and I don't feel like I should have to pay for it. They said well it sounds like you already did the work for us. I guess it was still under warranty but I got a new phone the next day and no problems since. Hopefully whatever was wrong they have fixed the issue by now but so far so good.
Definitely mention the mmc read fail error or whatever it says. All it cost me was a $5 charge. Give em a call.
I have the same problem, and it only happen when I update the phone to newest firwame, DOK2.
When I use COG1 firwame it very fast and easy use. but when I update DOK2 over Odin, I few very lag and usually restart the phone when I run a big application, then It can't restart after, just turn off.
And after that, can't turn on the phone. I had remove pin in 10s, pull in and it power on normal.
Sometime I turn on the power and the phone go into download mode with notice "mmc_fail can't boot".
Now I just only want to download my phone to old firwame, COG2 and use it normal, but the new firwame with new bootloader don't allow to download old bootloader. So sad
anyone can't show me how to download to COG2 firwame, Please....

Hello there, I'm having the same exact issue lately, phone is a Year old, and I think its failing, One question though!
Was your phone ever rooted? mine is, but I flashed the Stock DOK2, so its official with NO root now, but I think the Device status is CUSTOM not official, Also KNOX has tripped while rooting, would T Mobile honor a replacement? At least its on the Official OS with NO Root now.
Please enlighten me

Make sure you are using the ODIN version 3.10.7 if you are using an older version of may be what caused the issue.
If you did use the newest Odin, then I would factory reset your device, but into twrp and wipe everything but external SD Card, boot back into download mode and flash the firmware again. Most likely a few files for messed up during your Odin flash and it messed up the process. Also make sure you are using the USB cord that came with the device.
I found the fix for this mmc_failed. Making a new thread for this.

All help needed, is my note 4 dying ?

Hello.
I have a Galaxy Note 4 SM-N910T2. In january of this year i upgraded it to 6.0.1 (N910TUVU2EQI2) from 4.4.4(N910T2UVU2AOG1) using the SM-N910T firmware for the upgrade, everything was working perfectly but the day before yesterday i wanted to perform a wipe cache because the phone was being a bit laggy. after the wipe cache was perform and i hit the reboot, the recovery got stucked on Verifying DMhash tree. so after 30 minutes i took the battery out and powered on my phone, the problem is: The phone started to freeze, reset it self even the process system crashed. I read that downloading the Wake Lock power management helps and it did but i didn't want to use this app forever so i downgraded back to 4.4.4 it's original firmware, it does run better but now my phone reboots itself and it freezes just a little bit. Also i've got the Process system is not responding do you want to close it?
Things i've done so far:
1- Reflashed 4.4.4, 3 times, i've done wipes before reflashing and after. Nothing
2-Flashed TWRP wiped everything, repaired the file system, Flashed the stock again (4.4.4) nothing.
I'm not going back to 6.0.1.
Do i have to buy a new phone or maybe a new rom with a kernel will help ?

All i can say is your phone mmc chip is about to die soon or later you will get mmc_read failure message and your phone wont be able to boot into the system and you won'tbe able to flash anything.
My best suggestion is sell it ASAP.

I came across the mmc_read failure before I realized it was happening and have been researching ways to at least verify there was nothing important on the device before retiring it to Samsung heaven.
Instead of useful advice, everyone seems to be spouting "sell it ASAP" as though it doesn't make you trash as a person to attempt selling it as any sort of working device. The inclusion of "ASAP" and lack of "with a disclaimer" tends to suggest they aren't recommending you actually tell anyone about the issue.
Good advice would be to back up everything you can now and begin looking for a new device. You could attempt to sell it for parts, but make sure to inform people of the situation. If it is that close to failure, chances are it will still be well within the 30 day return policy on most sites and they always favor the buyer. Your device is already ruined, but there is no reason to destroy your reputation with it.

Question SM-G998B Bricked

Hey guys, second time this issue has happened now for me but seems worse now. I used posts from here to resolve back in March when device got stuck in a boot loop after an OTA update, I managed to use Odin and a firmware from Sams Mobile to flash the phone and get it working again.
This time seems different though, I haven't tried the above steps yet, but none of the drives are mounting in the android recovery menu, which makes me think the device is going to need replacing. Anyone else come across this?
Seems different?
Well I would try Odin and an official ROM anyway, no pain no gain right?
What exactly were you doing before this occured?
You try the old delete usb driver, restart computer, install usb driver then restart computer and restart phone and try again.

This time seems different though, I haven't tried the above steps yet, but none of the drives are mounting in the android recovery menu, which makes me think the device is going to need replacing. Anyone else come across this?

there is never a bricked device for good just keep searching using very device speacific info, check on youtube and search the names exactly as the ypop up there will always be something

Looks like he bricked his bootloader's storage access driver, which AFAIK is unrecoverable unless download mode / sahara / etc is fine, but if the board is refusing to mount data while in the bootloader, it's safe to bet the rest of the modes are ****ed.
To answer a few of your questions in one go:
When I flashed it before it was back in end of Feb so a good while ago.
Just before it went into this boot loop it was working normally playing music in my pocket while doing gardening.
Using ODIN this time failed as I don't think it could access any of the drives.

Oh I see the issue now you need to wipe all and re-flash full firmware when flashing the device using Odin
if that doesn't work flash the partitions with the kernel drivers and system partition
I had a similar issue with my current mtk phone and it was because the boot/preloader partition bilieved i had flashed the wrong firmware for my device(it was just a different firmware release for my phone
Just to be safe some ota updates break wehn the bootloader is not unlocked (when updationg from say android 8(oreo) -9(pie)...)
especially because of code errors in the update, cache/vendor partition being too full after downloading update

If you're telling the truth, and it wasn't a bad module / firmware / etc, it is possible your eMMC got too hot and melted some solder. I've seen it happen before.
You'll want to diagnose everything you can. If you're on Windows, does it recognize a USB device or a COM device? If linux, does lsusb return anything useful about it?
If it's not being detected, and multiple wires doesn't change anything, are you able to access sahara mode / download / DFU? If so, go to those and try again.
If you are lying, and this is a bad firmware flash / OTA brick, you'll need to tell us otherwise we'll be going in circles.
So ODIN does recognise the device when in android recovery mode i choose the bootloader, but when starting it, it fails. I'll give it longer tomorrow but my inclination is it's a chip failure. I don't know hot to tell if it was a bad firmware flash, but the first (and only) time I flashed it was back in late Feb / Early March, and I have been using it fine with many OTA updates since then using the phone normally since. Before the boot loop I was playing music via Bluetooth speaker but the battery died while gardening, which the battery died on so played music directly on the phone (no update or anything) and the music stopped halfway through the song and it was in a boot loop.
I am taking the phone in for repair on Wednesday but it's really frustrating because I legitimately want to get to the route cause of the issues. I am covered by Samsung Care +, but I feel like if I screwed up the first flash, it's still only as a result of that first OTA update going wrong in the first place. Does that make sense?

I'm going to call hardware failure. It's extremely rare that any device will do what yours is doing without a bad firmware flash.. It's possible you had an OTA and it auto updated, then broke, but I doubt it.

I appreciate the vote of confidence, I don't think it was an OTA update that did it this time, it usually requests to do updates which I highly doubt I would have pocket approved through a flip case only short after pressing play on Spotify.
So I have taken it into Samsung for repair and they have confirmed it's a hardware issue that feels vindicating!

how much are they charging for the repair though? probably a motherboard replacement ? boy thats not going to be cheap!

It was free, turned out to be a hardware issue internally so I think covered by warranty as I have Care+ which has an excess of £40 which they didn't make me pay. They also replaced the screen due to some dead pixels, and the battery! Happy days!
Thanks all for your suggestions!
