Stuck in boot loop for no reason - Galaxy Note 3 Q&A, Help & Troubleshooting

For no reason my phone just restarted. It used to restart from time to time and all was fine but this time its in bootloop. I currently don't have any recovery installed on it but I can enter in download mode. Is there any way to fix it without losing any data? I have some pretty valuable stuff that I can't really afford to lose
Its the LTE version and its running stock kitkat
I had different roms before but in the end I came back to this as everything else had bugs and wasn't stable
Also lately my battery life went to ****. From an average of 5hours SOT I can barely have a bit over 2 hours, sometimes not even 2. And I changed the battery with a new one and still no change. For some reason bellow screen I have android system as 2nd main consumer but I have no idea what could be using it. Could it be hardware??

Suggest flash custom recovery via Odin if you have no backup .
You may then be able to recover data .

[Help]Note 4 Battery draining fast :(

Hello.. I'm sorry for my bad English grammar, if you don't understand, please ask me.
I don't think I understand my phone well so I'll just tell you what happened then.
My note 4 is 1 year old. I think it is Thailand's model as I checked the model number when I'm rooting it.The battery life is long lasting when the first time I got it, I'm not sure when the battery life start to get worse. I'm pretty sure it is happening after Lolipop update, not sure if happens before that. I do not install much games, I do have like 5 or below games from playstore, small sized one. I do installed Clean Master to clear junks when I started feel lagging.
Until recently, because I needed root access to backup my game app data so I went root my note 4 using the odin method. I'm still in my stock firmware. I did faced a problem when Security & Policy update pop out , I did update and it went bootloop(I think it's called that) until I can't access into my phone, I did pull out battery then insert back few times and seems like it rolled back. These few days I was researching how to extend my battery life, I read lots of post said some apps is draining apps as it still not yet adapt to lolipop update? also saying Clock apps draining apps, not even wakelock detector able to detect it. I tried SetCPU and set my CPU below 800 Mhz and even 400min 500max(Just a question, why I didn't see On Demand ? Only Interactive, Performance & userspace) , I did not see any obvious results after doing all these things. Oh , I even went uninstall some bloatwares, I did download Greenify and hibernate some apps.
Now, I'm trying this method to see if it solves the problem. http://forum.xda-developers.com/andr...-life-t3095884
When I was about to Nandroid Backup my datas, to confirm it is it
1. Boot into recovery mode
2. Backup?
But then I couldn't boot into Recovery Mode( Volume Up + Home + Power ) just now, It stucks at boot screen, before the animated samsung appears, just Note 4 with model names something. There's no blue text above, and it just stucked there. The only way to exit from there is pull out battery and insert back again. I'm planning to download QuickBoot and try if can access to Recovery Mode.
Seriously, I don't know much about mobile technology, I just wanted a smooth phone with great battery life. I suggest to stay with the stock firmware, I'm still considering flash it to CM12.1 , people said it help with the performance and battery life, I do not like the interface of it, unless it solves all problems if not I'll not choose to flash into that. (Oh, can I use Odin3 to flash this? Can I use Odin3 to flash every rom? I don't really understand about rooting, is there any newbie guide for these kind of things?)
My questions are:
Can you suggest me few ways to solve this problem?
Is the method does help to my phone?
Why I can't boot into Recovery Mode?
What happened actually?
Edit: Or even factory reset or wipe partition(if I'm able to boot into recovery mode) helps? i did not try it yet.
Thank you for reading this even you can't help me.

[N910F]Random reboots (links to logs included)

Hi,
My N910F has recently been acting weirdly. It either randomly reboots itself, or just freezes for several seconds when switching screens or scrolling/tapping buttons. This started a couple of weeks ago on stock 5.0.1 (this version, I think) running Emotion kernel. This was running fine for a while; I didn't flash any new mods during this time, although I did switch between AEL kernel and Emotion once or twice without much success.
Thinking it was just one of those situations that called for a clean slate; I backed up my important stuff, booted into TWRP to wipe all partitions, then flashed stock 5.1.1 via Odin (this version, which I'm currently running). But even before I rooted it once again the phone was displaying the same aforementioned symptoms, both during and after going through the built-in setup wizard. This behaviour continued after flashing TWRP and AEL kernel v8.2, which I'm currently on at the moment. If it makes any difference I've also noticed that the lower my battery level, the more often it reboots itself. The battery level also "yo-yos" sometimes, usually at lower levels.
I've uploaded the relevant logs as advised elsewhere for anyone who can decipher them, as I otherwise don't know what to look for. This includes my last three kmsg dumpstate logs (just in case it's a slightly different cause each time), as well as my logcat and dmesg files (whatever they are lol) which I got using the SysLog app.
Any help would be appreciated, and if you need any more info please let me know.
Thanks .
*bump*
I have the same problem. Help would be highly appreciated. : )

[UPDATE]: Once or twice when it's crashed as above, it would try and boot again but then reboot into download mode with the following text at the top of the screen above all the other info:
Code:
Could not do normal boot.
ddi: mmc_read failed
If I then pull the battery and turn it on again, it boots up as normal (at least until the next crash). Is this something that can be fixed with a fresh flash in Odin (or some other method), or is my phone on the way to its death?
Got the same issue + loses Wifi password after random reboot. Sent the phone back to the operator I bought it from 1 week ago and they did a repair. They replaced the USB-flex, did a firmware upgrade(?? ..was already updated to latest) and sent it back. I got it this morning and at first the phone now works fine and no more "mmc_read fail". But after some time the random reboots started again. Not so often now but still 4 times over the day and twice the wifi-password is lost and I had to retype it. Now I'm on the fence and just waiting for the first mmc_read fail" to happen before I complain and send it back for a second repair. I can not imagine this beeing beeing other than a hardware fail coming from a weak spot on the phone. I got the impression many people has the same issue and it really comes to life after upgrading to 5.1.1.
I also think the problem at the service shop ist that they just do a quick system test on a clean wiped phone and can't find the issue and think the phone is fine. After reinstalling my 200 apps and setting up my phone all over again, the workload causes the issue to reappear and I now have to ask the service shop for a deeper check. They accepted this as a warranty fix all though my phone has a knox trip (0-1)x4...
I've also faced random reboots on Lollipop. How i solved that? Simple. I downgraded to Kitkat. Lollipop still having lots of battery drains and bugs even on 5.1.1
[UPDATE]
I've decided to go through my network provider to get a replacement sent out to me, which they were happy to do after going through their line of questioning over the phone ("have you tried turning it off and on again", "did you try taking out your memory card and see if that helped", "did you try doing a factory reset", etc). They say it will get here tomorrow so fingers crossed for the replacement.
The ddi mmc_read fail has not reappeared yet..
It's strange.. Lately the random reboots are not wiping my wifi passwords anymore, but now after every random reboot the multiwindow is enabled and I've got to untick it in quick settings..
Latest: It seems that the random reboot may come from heavy account sync workload. I did have 5 Google accounts syncing on my phone + 6 excange accounts and when i disabled syncing alltogether the phone ran a lot smoother and the reboots stoped. So i deleted all Google accounts except my main account and for now thing seems to be fairly stable. I've also uninstalled all for me unimportant 3'rd party apps, reducing 3'rd party app count from aprx 200 to 150..
If things develop further I'll come back with more

Thanks fot starting this thread Jointfcfan...i am using 910P and have same issue of your post 1 and 4!!!!
Loosing hope on Samsung, it is really frustrating...
Tried cleaning cash, dalvic, reboots, on latest 5.1.1 k version...frozen all not neede games and apps ...only 1 google and 1 exchange account no auto sync
At next stage while rebooting it sometime going an error stating kernel panic and i have to pull battery to restart
Replacing USB-flex board at service shop has cured the "ddi. mmc_read fail" boot issue for good.
So to me it seems that when many people experiences this, the USB-flex board may have a built in design flaw making it a weak spot on the Note 4.
Also I found that the phone works A LOT smoother if using Nova launcher instead of TW. Random reboot count is way down and phone works almost normally. Still some lag, mostly when unlocking screen, but reboots happens only 2-3 times a day now. Still random rebooting enables "multi window" option every time..
I've also rooted the phone now using CF-autoroot. I've flashed Philz CWM recovery and using it to install Wanam Xposed. So now I can run Greenify properly in Xposed mode and automaticly hibernate apps including system apps..
NB! Be aware, flashing root and custom recovery trips Knox counter 0x1 permanently and MAY void warranty
I have also mailed my operator asking them to take in the phone a second time for check/repair, alt. replacing the phone. I guess when they did system check 1st. time without issues after replacing the USB-flex, it was done when phone was reset to factory and under no significant workload.

Reocurring Boot Loops, Hardware?

Hey all! I'm having a strange issue regarding boot looping that I can't seem to find an answer to on here or anywhere else, I hope you guys can help.
So my T-Mobile Samsung Galaxy S5 (SM-G900T), purchased in May 2014, while perusing Facebook the other day, randomly shut down in the middle of perfectly normal use and started bootlooping. I had never had the problem before. The device had been rooted for months (I forget what method I used) but it was running a stock Lollipop rom. The first thing I did was factory wipe and cache wipe through Android stock recovery. It worked!... for a couple hours. Then the bootloop started again.
I went and sought a new stock rom, believing that somehow mine had been corrupted, and flashed it via Odin. I also flashed TWRP. Clean wipes, new rom, dalvic/etc. wipes, and booted into stock Marshmallow. It worked!... for a couple hours. Then it started bootlooping again. I went into TWRP and tried to wipe just caches and whatnot, but it wouldn't start again. Long battery pulls sometimes allowed the phone to boot, but it started looping again after ~5-10 minutes.
So I installed the Twisted Lollipop but couldn't even get that to boot. I went back and found the earliest available firmware for my device (as I bought mine right after it came out) and flashed it. Wipe wipe flash wipe whatever, and a succesful boot. It was looking good! I was able to install a number of OTA updates. I was at Android 5.1 when I decided to call it a night and hold off on the further OTAs for today. Today I got up and got ready for work, all's well. As I'm getting ready to leave, I allow Google to update some apps, and begin installing Facebook, Spotify, Cap Metro (for my area's public transit system) and maybe something else, I don't remember. Anyway, as the updates are downloading or installing and I'm checking my email, boom, crash, bootloop.
What's going on here? I've never heard of hardware causing boot loops, but could it be that? I dropped my phone (although protected by a Spigen case) earlier this summer and it cracked the screen-- could it have messed with the motherboard in some substantial way? I had noticed it getting hotter and the battery lasting less than usual, but I attributed that to the device's age.
Any help, any advice, any direction you could give would be extremely appreciated. I don't have the capital to replace the phone right now, and I use it all the time. Thanks folks!

Optimizing Apps on every boot.

I noticed a week or so ago that every time I reboot my Nexus 4, I have to sit through the optimizing apps every time. I have been going crazy searching for info on this and cant seem to find anything that helps. Phone is running 5.1.1, nothing custom, OTA update. I tried rolling back to 4.2 and everything seemed ok up until I got back to 5.1.1, then optimizing apps every boot again. I prefer Lollipop, but this constant half hour + delay before I can use the phone is unacceptable.
Any help would be appreciated, I really can't afford to buy another phone right now but this is driving me crazy trying to figure it out.

I'm not an expert but I have some experience with my Nexus 4..
any root? SuperSu maybe?
You receive the 'Android is starting optimising app xx of xx'?
if you have SuperSu, install the last version...
Another cause may be some file in your internal storage, make a backup, delete all and restart 2 times to see if there is a change...
Last resort, flash the rom stock with nexus root toolkit with all wipe
I did use NRT to flash 4.2 back on and wiped it, then let it work its way through the upgrades again. Once it got back to 5.0+ the optimizing problem started. Phone was not rooted, just bootloader unlocked.
I flashed a custom rom based on Oreo on it and the problem stopped, so I am assuming this is a Lollipop problem, but I would really rather be able to run stock Lollipop on my phone.

Lenovo A6000Plus Bootloop problem (Unrooted device)

Good day everyone, i am going to report my delicate and infuriating problem that has been haunting my head for two months
I'll describe my problem in extreme detail, hoping you guys able to identify this disaster.
My android phone is Lenovo A6000 Plus, i've bought it 2 years ago and it's running on latest Lollipop version 5.1.1 I never alter the system files, since i only use my phone for games and communications, and i'm not really into tinkering android's software. so i use my phone like a normal person, do the updates when the settings asked me, update the apps, etc. and this phone running smoothly in my service. i wanted to ask both WISDOM and HELP in this thread.
1. The Bootloop disaster symptoms started on april 2018, when the phone boot SLOWLY AS HELL, seriously.. it took about 1-2 hours to boot, and it also shows the (ANDROID IS UPGRADING 0/132 apps) like wtf? , i haven't update or install any new android apps before this symptom happened. So i leave my phone plugged in and wait it to complete the upgrade; then it worked normally as it should. Unfortunately, it happened EVERYTIME i turn my phone on, EVERY SINGLE TIME.. T_T. so i struggled to avoid my phone from running out from battery as i can. This symptom happened for 3 weeks and it got from bad to worse. I wonder what kind of problem is this?
2. The worse part came when my phone is running at high RAM usage, let's say, i game on my phone alot in my spare time, using the ram up to 1800mb everytime i play game or open chrome browser (Lenovo A6000 plus have 2GB ram). When i close/task manager the apps, my phone launcher wont appear normally as it should (long pressing bottom left button) and it FORCED me to restart the phone and suffer the 1-2 hour LONG BOOT. That's unusual, i cleaned my phone regularly (using cleanmaster) and preserve both of my internal and external storage with 3-4GB free space. I wonder what kind of curse is this?
3. So the bootloop disaster finally got me this May when i turn my phone off and tried to reboot. And... no Android is upgrading 0/132 showed up, i waited for 4 hours and reboot my phone again and again and again. And its finally STRANDED on BOOTLOOP :crying:
Im on panic mode when problem 3 happened, then i searched the almighty Google for help, and found that i can backup my data with TWRP recovery, so i do as it said, followed the guides and BACKED UP all of my data.
For once i felt relieved my data is now saved. Now onto the main problem.
I've had enough of this problem so i format the phone into factory reset, wipe the Dalvik ****s, cache, system and data. All of it. thus, making my phone virgin again.
4. Now im trying to resurrect my phone, and tried my effort by downloading Stock Lollipop 5.1.1 OS again along with its prerequisites. I tried to zip-install it using TWRP but it said that "has not switched carriers and cannot be upgraded" i scratched my head and searched almighty Google again then found that i need to do ####6430### thingy before doing that. umm.. so my phone domain need to be changed, how can i do that with a phone who can't boot? (I'm from Singapore btw). What did i do wrong?? did my phone just turned into useless BRICK? but i've read that bricked phone can't even start the recovery, yet my phone still able to start either with Lollipop stock recovery or TWRP (if i adb fastboot it with adb tools from .cmd), so it's not totally fuc.. uh., BRICKED and i got the chance to fix it.
TL;DR
So, Guys.. i desperately need help. i'm a peon both in work and college, and a dead phone will not make a great company for a person like me.
I searched for enlightments and breakthroughs but always ended up failed resurrecting my phone, can you guys PLEASE :crying: tell/give me a SAFE and WORKING walkthrough to re-install my Lenovo A6000 Plus with Lollipop 5.1.1? And does it running a custom OS like those Cynadrogen thingy is good and worthy enough to speed up my phone? is the chances of getting bricked is unavoidable when running custom OS? I thought its going to be easy like reinstalling Windows, but i was wrong.
FYI, my phone now is UNROOTED and running on TWRP 3.0.2 and i can easily revert it back to Lollipop stock recovery if needed (does it considered rooting if i install custom recovery?) I also need a valid info if my phone would never turn like this again if i resurrect it again.
PLEASE HELP ME PEOPLE
THANK YOU.. ! :highfive:

When 5.1.1 update arrived?
Okay lets get to the point. Just don't panic. You have the stock rom file, extract a file named 'system.zip'. Now go to TWRP, perform advance wipe (wipe dalvik, data, system and cache partitions) and flash that file from TWRP. You'll be on stock rom with a fresh new experience.
---------- Post added at 10:38 PM ---------- Previous post was at 10:33 PM ----------
Custom ROMs are amazing and far better than the stock lenovo rom. Believe me, no one here is using that crap stock rom. You just need some instructions to flash and your phone will get a new life. We are here to assist you.
