So here's wbats goimg on with my phone now. Downgraded to 5.1.1 couldnt get it to boot past the samsung logo at all. I went back to 6.0.1 and still couldnt get it to boot. And when it finally did. It would freeze and shut off after 5-10 seconds. All while getting burning hot. This morning i tried to turn it on. It rebooted a couple times amd all of a sudden its working fine. Not one malfunction all day.. And ive been putting it to the test too.

What the hell is up with this phone. Haha if it keeps working its an absolute miracle

Originally, I was getting a secure check error... then I tried again with a different PIT file from another thread on XDA and it worked like a charm. 910T here also.

I attached the PIT file to this post. Let me know if it works for you.

SM-910T VARIANT ONLY
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Sounds pretty serious, especially compared to the issues I'm having. Logically, I'm thinking... if you re-partition the drive and the entire phone firmware has been re-flashed, etc... and it's still doing that, it's pretty clear it's a hardware problem. I'd be wary of anything burning hot, especially after the issues the Note 7 is having...
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] monkeyass408:
thanks i used that very same size pit file. worked and pass secure checks. Only, it didnt solve any of the issues on my phone even after repartitioning. I still get random lags and stutters and now i get UI fc and reboots. I dont think there is anymore hope for this note 4.

I'm having problems with my Note 4 too. Two weeks ago rooted to use WiFi Tether app. Everything was fine up until this week. Phone freezes like a MOFO. Reboots randomly and extremely unstable. I uninstalled root/TWRP, re-flashed firmware - same problem... Had to go out and buy a new phone while hoping to fix this piece of crap.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] rymanh:
I haven't tried re-partitioning and wouldn't even know how to do that properly. My device is N910W8.

Tomorrow im buying a One Plus One. Im getting a really good deal on the 64GB version. Its a respectably decent phone and sbould hold me over for a while.

Ill still try to fix my note 4 though. But im 95% sure its a lost cause.

No more Samsung devices for me

Edit. No need to direct me to instructions or files for flashing a Pit file i did a quick search and found all i need
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
I really hate that it's coming to this (for almost all of us) and that this turn of events with the Note 4 has destroyed my taste for Samsung, but I may be done with 'em too. We are all having these issues, along with countless others who aren't on this thread... and Samsung probably won't do anything for us. I'm going to get a tech on the phone this week and explain the best I can what's going on. Even people without root or any custom ROMs have had these issues. I'm honestly surprised a class action lawsuit hasn't been filed. Clearly a defect somewhere.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] rymanh:
Yup. Its all over the internet, YouTube too.. a quick search will show that this is a widespread malfunction. It has little if anything to do with flashing software. It sucks that probably still one of the top phones available turns into the worst.

That's how samsung rolls
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] AntonJart:
My Note 4 screen began to have stripes of yellowing 4 month after purchase, went to Samsung service center - they replaced it, but a**holes chipped that cheap black paint from the bezel and forgot to glue the new screen properly. I had dust getting into the front facing camera, but couldn't do anything because service center said "Oh we use only soft tools and heat gun to get the screan off..." Fast-forward to now. Rooted about two weeks ago for the first time to use really cool wifi hotspot app. Used hotspot for two days, and then 10 days later my phone went to ****. Reboots, freezes, and so forth...

My buddy's Note 5 had the same problem. It would work for a bit and then start rebooting and getting stuck in the boot-loop. No modding ever! They had to replace the mobo.

I lost faith in Samsung at all! My HTC One M7 took so much abuse and still works flawlessly! Samsung Galaxy SII still works, Nokia Lumia 920 still works, but Note 4 is a paperweight now!
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] rymanh:
Htc makes great phones with awesome build quality. Ive had a couple. Plus i have a nexus 9 the build quality on it is terrific. Its taken a beating and still not even a scratch on it.

Unfortunately i had to jump ship from the note 4. It was pretty much toast

I got my oneplus one now. So far it feels faster than the note 4 in daily use, albeit the screen isnt quite as nice, the camera isnt quite as nice and its slightly smaller. There are a few other caveats. But none of them are deal breakers. All in all its not much of a downgrade. Plus the xda community is still poppin over there

So long! Note 4 community. Its been fun
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Things have only been getting worse on my end. At this point, I'm deathly afraid to reboot the Note 4. It goes completely black and I always have to pull the battery, de-energise, and let it sit for a couple minutes. Then power on and hope I don't get mmc_read failed. If I get past that point, I have to hope it gets past the animated LP screen and doesn't just loop on it for eternity. Took me almost 45 minutes earlier to get a proper boot. I also tried restoring the ROM... same thing happened immediately so I'm 95% sure it's a hardware failure.

During one of the boots, I got a "KERNEL PANIC!" message. I couldn't photograph the message but this one is almost (if not) identical to what I saw.

Kernel Panic!

[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] SteveRiley:
Sounds like the road to Perdition a lot of us are on. I take regular backups now and am essentially waiting for mine to die completely, then I'll replace it. The ability to root is a must for me. I'm leaning toward getting a Nexus 6P when the fateful moment arrives, as it looks like Google plans to price the Pixel phones in the stratosphere.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] duh-rel:
Kernel panic? That's an error I haven't seen on my Note yet.

I've given up on trying to get booted. It's factory restored to MM and sometimes it sticks on one of the boot images (most often T-Mobile) for minutes on end. Other times I get the black screen with no response requiring the battery pull and de-energizing. T-Mobile should be sending me a replacement soon. It's been on back order for over a week.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Are you still under warranty? My Note 4 will be 2 years old next month so clearly out of warranty and T-Mo refused to do anything for me. I have yet to speak to Samsung at all about it.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] duh-rel:
I'm out of warranty. This is my second Note, a refurb I've had for about 14 months that replaced my original preorder that had a faulty camera.

I was able to process a warranty claim with Samsung but they returned it saying it was Beyond Economical Repair (BER). They saw Knox was tripped and probably didn't even bother looking further into it. The process took about 2 wks.

If your Note doesn't have Knox voided, I might advise you give Samsung a call. Otherwise, don't even bother with them.

Luckily T-Mobile was kind enough to do a warranty replacement. There's a couple other threads that I've read about this. I even read of one person saying he received an S6 replacement. I think the Notes were out of stock at the time of his request.

Try calling T-Mobile again. Hopefully they can offer a better solution. It's not worth you time and frustratation over trying to troubleshoot this faulty product.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Thanks a lot for this info. Just got off the phone with Samsung (prior to reading your message). Yes, my blood pressure is sky-high right now so I need to calm down before I hit up T-Mo again. It's so difficult to try to explain my problem while also acting innocent (as if I haven't rooted, installed custom firmware, used 3rd party apps like Odin, etc...) The guy on the phone was just talking in circles and annoying me so I ended up hanging up on him.

Anyway, let's see if T-Mobile will do anything the second time around. I'm coming to find out that it's definitely not worth troubleshooting.

Edit: SCOOOOOORRREEEEEEE. I called T-Mo and glossed over your situation. They said they never do that because warranty-replacing a phone that's not under warranty "would technically be considered illegal." But after explaining my issue and being passed around from dept to dept, as a courtesy, he added warranty service to my bill at $3.99/mo. After that, he immediately processed a claim for the warranty. The phone is on backorder so in this case, no upgraded phone will be given. I'll get a brand new Note 4 from Samsung in about 12 days or so though. Just gotta pay a $5 warranty fee when I go pick up my phone in the store. All in all, successful day and finally, a resolution.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] monkeyass408:
i did this twice this year. The note 4 has mainboard issues. called loyalty. you are wrong to say you will get a brand new note 4 from samsung. They are adding insurance to make a claim for you as a one time courtesy. You will be getting a used/refurbished note 4 through the company that t-mobile works with, assurant. I have been told mines is backordered since the 19th. On the 19th they told me 8 days backorder. On the 23rd they told me 11 days back order. So its going to be a long long wait.... Also there is not such thing as 3.99 insurance. They are likely to add 12.99 but thats just a one time thing and you can take it off right away. I am keeping mines for a month or two just in case something comes up... i doubt that they will replace it free again.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
I'll keep an eye on the bill and see what charges were added because everything you've experienced goes completely contrary to the entire conversation I just had with the T-Mo rep. He said if T-Mo has the Note 4 in stock (in their warehouse), it may be refurb. But in this case since it's on backorder, it comes directly from Samsung. T-Mobile will unbox it and run a quality test on the phone so technically, they can't call it "new" because they've unboxed it. Also, instead of the normal $20 warranty fee that's assessed when I pick up the phone, it will only be $5. This could be some sort of special situation? I don't know... but there seem to be a lot of exceptions here.

I wish I'd had call recording enabled just in case there are any discrepancies with this process... but I guess we'll see what happens.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] monkeyass408:
if you want to check, just call or live chat in and give them your number and ask if you have insurance on that line that was requested and how much it cost. As for 3.99 t-mobile never had anything of that price for insurance. Also I had to pay then an extra 5 bucks when picking up. They are just sending you a replacement phone and it will not come with a plastic back cover, a stylus, nor battery. You reuse those three items. They will definitely not send you a new phone but just be happy you get a replacement. I will be happy as long as it works and the screen is not scratch... (my pet peeve).

right now i am hoping the back order gets way to long like a month and i will ask them to send me another... s6 edge or note 5...? lol

Im not going to be greedy. Just need a working phone to use...
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
I called them back and talked for a while to verify the info. "As a courtesy" (I love those words), he expedited the order... so every day they're going to check on the status and ship mine ASAP so I should get it before the 12-day mark. We'll see if any of that talk makes a difference. Yeah I asked him, "So if the backorder keeps getting extended, at what point do I get offered an upgraded device?" and he kept reassuring me that the backorder wouldn't be extended. Hmm. But he did offer a $20 bill credit for the inconvenience and an extra $6 credit to cover the warranty fee that I'll have to pay in-store.

Anyway, yeah I never used the word 'insurance' when I was talking about the $3.99 because it's not insurance. It's a warranty. And yes, it's $3.99/mo... confirmed. I'm guessing this service just extends the manufacturer warranty? But it doesn't protect it against loss, physical damage, or theft as typical insurance would. But it does protect it in this situation, and since the phone has no damage on it. This guy did use the word 'refurbished' when confirming the condition so I guess that's that.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] duh-rel:
Way to go forbidin! I believe I was informed of an 8 day backorder period as well and that was a week ago. I should call to check.

From my conversation, I would be sent a refurb and not a brand new phone; along the lines of what monkey said and having to use your existing accessories, battery, and back cover.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Thanks! I should have contacted T-Mo by phone 2-3 weeks ago instead of my "live chat" attempt; this would have been resolved a lot sooner.

Good info. My phone is in 10/10 condition so I really hope the new one is in comparable shape.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] ShrekOpher:
Has anyone found a solution to this problem besides swapping the phone out. Can't believe the update to 6.0.1 basically broke the phone.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Not according to everything we've tested so far, no. It's been largely reported as a hardware problem and considering almost every aspect of software has been troubleshot, it seems that way. Hardware issue won't be fixed until you replace or repair it. I wish there were a better answer.

A few people reported mmc_read error a couple months after the phone was released, so that error seems random. But the deep sleep problem started (at least for me) after MM. I'm not sure which OS my replacement Note 4 will have, but we'll see. I still plan to upgrade it to MM and I'm keeping the warranty on my T-Mo account in case this one screws up too.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] monkeyass408:
after three weeks (business days) they finally sent the phone out and guess what they gave me a note 5!!! it looks hella sexy in white! so stoked. Time to root it and flash!!! I will still be around the note 4 forums cause i have a note 4 spare too!!! I dont know how i tell about not having micro sd card and no removable battery and no IR blaster but hey i got a replacement note 5 and wont have to be afraid of when that will die!
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Nice, you got lucky! The jump from the Note 4 to Note 5 isn't that big, and with sacrifice (like you said) of the microSD, removable battery, and IR... so I'm not sure which I'd rather have. But yeah, at least you don't have to worry about these catastrophic Note 4 problems. I'm leaving the warranty on my account in case I have issues with this one. I would have loved to get an S6 or higher though :crying:

It only took 4 business days for me to get my warranty phone. Talked to them that Monday, it shipped Friday... I got it on Monday (03 OCT). 9.8/10 condition, everything nice. Already rooted and flashed OvrDriVE's Marshmallow ROM. Running smooth, no issues at all.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] monkeyass408:
yeh i have no clue why i got the note 5 then. i was complaining about their slow back order maybe? They said there was a huge back order cause samsung isnt sending them any. I check every couple of days and it was always 10 to 18 days back order and it increases each day. im in the bay area and i ordered on the 17th of last month. Maybe location is a factor. Im just loving t-mobile for doing the warranty thing though. Props to them.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
After the concerns raised here, that's when I called them back. He gave me a $26 bill credit (no idea why... he just kept apologising haha) and he put my order on expedited, which sent me text messages every day on the status of my backorder. I believe it moved me to the front of the line as well. I could have probably gotten a better phone had I waited longer, but I'm satisfied because this was kinda urgent; I couldn't even reboot. When I was preparing my broken phone to give back to T-Mo, I ODIN-flashed DOK2. Success... but my phone wouldn't even boot up. It was still spinning in a bootloop when I got to the store.

I said the same thing. It's about time that cell phone companies are helping out their customers. Had this been an in-contract situation, I bet they wouldn't have budged at all, but being prepaid, they realise we could leave anytime. Can't beat a replacement phone for $8.99 out of pocket. Screw Samsung. A $750 device should last more than 2 years.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] ShrekOpher:
Yeah no insurance for me on the device. It is out of warranty and I use it on AT&T. Doubtful I could get a hardware swap.

However I got it to boot again and repair the partition. It was a pain and took some guess work but the phone is running good-ish now. Good enough to keep as a dev device.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] BklynNetschamps:
Can anyone remind me why MM is better than LL? What defining features make it a must have... My phone experience was much better on Kyubi heavy debloated Note 5 port but that was a LL one. The only thing that keeps me from going back in now on tap..

And plus, I have never went above 3hrs SOT, maybe 1.5-2hr on a good day with my N4. Its puzzling when I see reports of 4-6hr SOT, making me think whether I have some defective unit...

I bought my N4 a couple of years using an Amex card, I wonder if they could provide an extra warranty to exchange?
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] sentron:
I have the same random freezing and rebooting issues also. I got a notification today that there's a new OTA update, and may websites say it's the Oct 2016 security patch. Does anyone know if this OTA fixes the freezing/rebooting issue? I plan to apply the update, but wanted to check if anyone tried it out already and whether it fixes the freezing/rebooting issue.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] darekz:
Maybe it is too early to say it fixed that but since I applied update on friday, I had not a single reboot. I used to have them at least once a day before. I even had to disable sim card lock because sometimes I found Note in my pocket waiting for me to input sim unlock code while many calls and emails/text were missed.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] sloanster:
Wow,

I thought I was alone in this process!

Sorry, for arriving late to the party...

it all started with me with the MM update or did it?

I posted a couple days ago an still in testing mode about the micro-SD card!

I'm really not sure sure but when I pulled out my older 32gb SD card out of the drawer and replaced the 128GB Lexar card...

My phone has smoothed out.

It was black screening, mcc failures, resets, even kernel panic, just a hot mess!

NEVER had these issues, but will keep you posted.

Please read my post under troubleshooting SD card and respond if you have any ideas.

Stay away from MM, maybe dok2 would be my choice...

And maybe a timeline, it's almost impossible all motherboards have failed so close to the MM release or did it?

I have the same issue here except that it happened to my note 4 on which i have never rooted not installed custom roms, and on top of that it happened after getting the latest updates which included October security patches.

I also face another issue on which the phone take long time to boot and if i boot on recovery mode it always take like ten min stuck on the installing updated screen on which it then shows the recovery options /same apply in the normal boot it might stuck on the boot up screen for like 10 min before it present the t-mobile screen. Any idea what might be the problem.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] forbidinjustice:
Yep, unfortunately I saw that it had happened to Note 4 units as early as November 2014, a month after the phone was released.... no root, no custom ROMs. Samsung still tried to blame "custom software" being installed on the phone. Unfortunately, I have no real response to your question other than we've discussed on the many pages of this thread. We've tried a ton of things and most of us have gone on to try and get our phone replaced since everything points to a hardware issue. The symptoms tend to be erratic and sometimes get better, then get worse again. T-Mo replaced my device about 5 weeks ago.
