Weird Boot Loop...

Hello, yesterday my phone started a boot loop. I managed to flash an official rom jelly bean 4.3 and i erased all data.
After flashing the phone worked for 2-3 with no problem, but after that it stuck on boot loop again.
The weird thing is that when i plug in the power adaptor the phone boots normally, it works ok, but when i unplug it after a few hours suddenly restarts and stuck on boot loop.
Does anyone know what to do?
My phone is Galaxy s4 gt-i9505 jelly bean 4.3 official

What rom were you on before you flashed the stock 4.3? Also what bootloader and baseband is your phone currently on?

I was at jelly bean 4.3 before but rooted...
Here are the infos

That looks fine.
Try wiping your cache and data again.

I had the same problem replaced my battery since you have still a warranty on your phone go to the store where you bought your phone and let it replace under warranty.
the original battery is from a bad serie that starts to swell after a month or 2. check out this thread:

Yes probably your battery. Just bad luck.

Same problem here. a new battery is also the fix?

Had the exact same problem, phone would only boot up with power cable connected. Happened right after the 4.3 update, so I thought this was connected, however it wasn't. After a battery exchange the phone has been working fine every since.

Slow Charging on Lollipop

Hi guys
So yesterday I flashed the lollipop Russian firmware
And I've noticed that the phone is taking almost double the time to charge than it was on kitkat
I already tried a factory reset and wiping cache partition but it doesn't make a difference
Is anyone else facing this and please give me possible solutions?

My phone takes about 2h to full charge. I think it was the same when I had kitkat.
Do you use the charger that came with the phone?

Yes
I use the charger and USB cable that came in the box
and I've tried reflashing the firmware
I'm starting to suspect that my cable might be damaged or that the bug is just lollipop on my phone

Note 4 diarrhea

Hi, I'm kinda lost ma mind right now.
Here's the story, my friend has note 4 SM-N910F Qualcomm , suddenly it began restarting with abnormal battery dropping.
I began repairing by trying to perform factory reset, to enter into a boot loop (without a root till the moment). Then I charged it fully which made it work.
I tried to root then install CM to replace stock rom (to repair any system issues), which was quite difficult, as I tried to install CM 12.1, it keeps fail due to incompatibility (the CM rom for trltexx and mine trlte as the root keeps shows me)
BTW the root I used was ( openrecovery-twrp-2.8.4.0-trltexx.img.tar ) *yea it confusing*
Finally I downloaded official stock 5.1.1 , and installed it, it finished well and booted also quite well, as language selection screen appeared, same original issue reappeared again ( *keeps rolling in boot loop* )
Now I'm worrying about hardware malfunctioning.
:silly::silly::silly::silly::silly::silly::silly::silly:

I accidentally posted in Android development. so sorry

I've seen this issue on my friend's tab s. The screen would freeze then it would reboot. This got worse as the battery power doped to the point that swiping to unlock would cause a reboot. The problem turned out to be the battery. It may be worth buying a new battery for very little money to see if this fixes it.

I'm in a doubt about the battery, I think it's slightly swollen.
I guess I'll give it a try.

Install Custom recovery thro' ODIN (philz_touch)
Flash Nameless Kernel v 6 thro custom recovery.
And I think you are done.

If you tried factory reset and flashed a fresh stock rom and its still happening, the battery is the problem and also check if there is a micro sd inserted. If so, remove the card and check.
No custom rom or kernal will be better since they come with thier own bugs and not as stable as official firmware period!

Restarting phone?

I was using my phone one day and it just started restarting. It kept on restarting over and over again. When I plugged in the charger, the phone stopped restarting and was able to turn on normally. The battery was 50% when it started to continuously restart. Once I plugged in the charger, it showed me 50%. After turning on (plugged), I unplugged it, and it took about 20 mins then it's restarting again.
What is the problem with the phone and what should I fix?

Hello,
I have the same problem with my S5 (G900H). I was on Android 5 Lollipop and received the 6.0.1 OTA update and after that the phone became unstable and keeps restarting (unless I connect it to the USB charger).
I have flashed it with Odin and the issue persists. Let's see what we can do to get these phones working again.
Did you received an update recently? What model is your phone? Have you flashed or made a factory reset?

I have the update but the problem happened way after I got it. Unrooted and no factory reset done.

I flashed it with a new stock ROM released from Samsung and now I don't have recovery mode. Keep reflashing with other ROMs to see what happend.

I have fixed the problem. It seemed to be a dodgy battery. Got it replaced.

I'm gonna find a new battery and test it. Thanks.

The new battery will be delivered tomorrow night....

Problem SOLVED!!! Got the new battery and my phone is working again.
Could Samsung thru its OTA updated damage the battery to make you get the new galaxy?
My battery was fine until I got the OTA update!!

Yeah there is a possibility for that but I cant be 100% sure

Nexus 6p Bootloop Fix/Workaround

After upgrading to Andriod N on the 6p, many of us have been plagued by the Bootloop of Death and/or random reboots. Some have tried RMAs, have purchased new devices or moved to backup devices. Huawei has claimed software is the culprit and Google has stated that it's the hardware. Personally I've tried a clean install of the ROM, Dirty flashing the ROM, clearing the caches, etc.
Nothing has worked... Until now!
I'm days in without a single random reboot or Bootloop.
This advice is provided without warranty or any guarantee that it'll work for you but it may work.
I'm not a developer and I've not tried multiple devices.
Steps:
*Note I'm on the latest Pure Nexus build.
1. If you're currently stuck in a Bootloop, then leave your 6p to Bootloop until it actually starts or until the battery dies. If it starts skip to step 3.
2. If it Bootloops, then intervene occasionally by getting the device to boot into the bootloader (Hold down power and volume down). Once there, attempt to reboot recovery. It'll probably keep Bootlooping but occasionally the device will start up.
3. Once your 6p starts, download the ElementalX apk from the Google Play Store. Don't do anything else. I've only tried this app so it's the only one that I recommend for this "fix".
4. Download the ElementalX kernel through the ElementalX app and follow the prompts in order to install the kernel. Allow it to reboot. *You may be able to complete the following steps with the stock kernel.
5. Once your device has rebooted, open the ElementalX app and click the leaf icon in order to enable power saving. This will lower your CPU's freq, GPU's freq, and most importantly, it will disable the BIG CPU cluster.
After these steps were completed I haven't experienced any random rebooting​ or Bootloops. Yes, this ”fix" hobbles your device but it is still quite functional. I think that on Nougat the constant switching between the two processor clusters causes random restarts and Bootlooping​.
There may be an alternative that will allow you to disable the little CPU cluster instead and not lower the GPU performance. I've not tried any other methods yet.

Recovery: TWRP

Please comment with results.

Multiple people have reported getting the boot loop of death while on Marshmallow. I think the idea that Nougat is causing the problem was discredited long ago, the fact that its a hardware issue with these phones is widely accepted and that the age of the phone is much more of a factor than the operating system you are running. Most of these phones are experiencing the boot loop of death shortly after the warranty expires, when the phone is 12-14 months old. Your phone is generating less heat since you ramped down the CPU which is likely why it isn't currently bootlooping.

Well...

You may be right but I didn't notice any Bootloops or random reboots until I upgraded to Nougat. After putting this "fix" in place my device still gets pretty warm under load but it doesn't exhibit random reboots or Bootloops... Heat didn't seem to be the issue since my phone would reboot into a Bootloop while just sitting on my desk at work with only background tasks running. Regardless, this workaround works for me and it may work for others.

Mine just reboots over and over, for days and days, my bootloader is locked and usb debugging is off.

HOW would one install APk from playstore if their phone can't even load up, aka bootloop of death ? You need to be more specific , like locked bootloader , unlock bootloader ..etc.... smh

Once battery dies what i have to do? (my phone dies two hours ago when I was with a 3% of charge and its bootlooping over and over) Full charge? Another thing?
Note:
1)I'm on the latest Pure Nexus build, stock kernel, unlocked bootloader
2)When i connect to the charger one hour ago the phone shows battery charge mode but stills bootlooping. I'm waiting to battery dies

Sorry that I wasn't more specific. My bootloader is unlocked and I'm rooted. Users may not need to be in order to get back the device's functionality.
It's a shot in the dark but if a user that is having the Bootlooping issue follows my steps, then they may get back up and running. I've yet to have another random reboot or a Bootloop since...

Since it's died, you'll need to power it on once it's charged for a while. When you power on and it starts Bootlooping, boot into the bootloader and follow my steps. If it Bootloops continuously, boot into the bootloader again and try to get into recovery. It will probably continue to Bootloop. That's what happened to me. I'd come back to it from time to time, boot to the bootloader, prompt it boot to recovery... over and over again. Eventually, it would fully boot up instead (not into recovery).
If it starts DON'T check messages or try to use your phone normally. Instead, follow the steps. Seriously. I made that mistake over and over again.
FYI: This process can take a looong time. Not days but sometimes it was hours until I figured my solution out. I don't know exactly how long it takes because I'd leave the phone Bootlooping and come back to it later in the day.

Many thanks!
Its work for my nexus 6p too
My nexus work normal in interval 1-5% of charge. If charge increase 11% - bootloop...
After enable powersave elementalx, charging to 100% and work well

I have a smartphone. Automatically went into reboot, but did not boot. It constantly reboots. First, the test is reflected that I've been unlocked by the bootloader, and then the Google inscription, and after that the smartphone reloads again. The recovery menu does not enter.

Thanks! Finally something that worked! The big cluster is indeed the problem. I had the porblem that the phone freezes and gets stuck in the bootloop when the battery is above 10-12%. I guess that the cpu disables the big cluster when you are underneath that threshhold(?).
One big problem I am still facing is that I can't reboot my phone and I have to make it discharge until I can boot it up again. Do you have have something that prevents that?
Big thanks again!

Still bootloops

I followed all the steps but my Nexus 6P still bootloops after crossing 10% charging. Is it possible for you to share your Kernel Manager settings screenshots please?

I too began to experience the boot loop issue literally 8 days after my warranty expired which was 11 days ago today! Have tried flashing several factory images from MM to N and even a saved backup I made from day 1 of having the phone. This method of disabling the big cluster thru ExK has definitely been the furthest I have gotten. Me and my friend(da guy) did find out that in order for the phone to boot up at all, the battery has to be at approx. 6% or lower. In that time is when you must quickly download ExK and activate power saver mode. I just called Huawei support and they did absolutely nothing to help me in this manner. I really do hope that this lawsuit wins in our favor. Speaking of which, does anybody know where we can check for status of this current litigation?
Update: Ordered a new battery and installed it... still bootlooping. This is very frustrating as i have been forced to use my ancient Moto Droid X2 as my daily

I wonder if someone could compile a kernel that always disables the big cluster for those with bootloop problems. Then you could just flash the kernel and not have to try repeatedly to get the phone to boot long enough to install the app.

I'll have to look into kernel building, but I'd imagine if you built a kernel that had powersaving as the default profile, it would work.

Got into recovery long enough to flash pure Nexus and root, but haven't been able to get it to boot yet.
Looking forward to one day being able to use it again. ?

I really want this to work. Can you please share your settings? I'm not getting passed 10-12% charge. It makes a loud noise and bootloop till around 6% but runs fine if it's below 10%. I can watch videos and listen to music

Same issue !
