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.

Thanks, but I've already tried that and it doesn't work. I'm forever stuck in the firmware update screen.

have you tried the CS_EMERGENCY option in R&D TOOLS? Wait I'll find the link..

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..

IT will mostly work..Good luck though and please do reply here and let us know if it worked..
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 been having the same issues ...even with full firmware flashed DOK2....I get internal memory failure. Hope someone finds a fix.

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.

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?

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.

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.

I have the B162 update running on my P10 and whenever I try to download an app from Playstore, it shows downloading, but nothing gets downloaded. So I did a hard reset and everything seems to fine. But only for a few days, again I can't download or update anything.
What can be the reason for this?
have you tried with 4G connection ? wifi connection ?
this morning, I couldn't get any app via 4G, I've switched to wifi and magic ! the apps got installed.

I tried with both and didn't work. But I found that when you keep the phone standby, apps will be downloaded/updated at random times.
Same for me.
If I reboot the phone, download starts immediately.
here is a troubleshooting tutorial from Google :

I too downgraded the play store, but no luck for me. Even the Huawei support is asking me to do a factory reset again. So frustrated now.
After update to B162 I am having problems with not being able to update or install new apps - a reboot seems to have fixed it - For now.
Same here, cant download new apps.
Been seeing the same since i got the 162 update on my P10 Plus, reboot gets it going again but definitely something to do with 162 update.
Getting same issue as well is it worth factory reset or maybe I should take back to network carrier my contract is with?

Doing a factory reset will only solve your problem temporarily. So better to wait for a fix from Huawei. They'll release one soon.
I'm on the same f/w, but have no problem downloading through wifi or 3G network.

No they haven't I guess. But there are many people who report this issue now. So Huawei must take an action immediately.
Same problem here since the 151 update. Huawei, this is not cool. Besides, I'm having a lot of syncing issues.
I have a problem, hope someone can help me.
First time i haven't rooted my phone lol. Since update my phone randomly freezes and reboots, sometimes it just turns off, which means it doesn't shut down but screen turns black and its off. I wonder if someone else has the same problem and could solve it or if someone knows how i could track this error to get rid of it. Some sort of logging program i could use for example but as i said phone is not rooted. Appreciate any help. Thanks
try clearing the cache or if that doesn't help manually download the firmware (on a stable wifi connection) and flash it again.
when did you get the phone?
share the phone's model number and the software version running please

well a factory reset will clear your cache for you but if that not where the issue lays you'll still be in the same predicament.
flash your firmware again if you need to. don't interrupt or pause the download and do over a strong wifi network.
