I hope you can help me to find out the solution gaes. So confused. My galaxy s4 is my life heeeeelpppppp

Or you have a faulty battery or your have some other hardware failure. What you should do is change the battery and see if that helps.

How about removing the battery for a couple of hours, then reinsert and charge it. Try entering download mode again to see if you can get into it. Or try entering recovery, you're still stock recovery? You can try wiping cache and rebooting.

No reason bootloop

Hey guys, let me start off by telling you I was running stock 12b rooted with the 1.5 Furnace kernel. Been running that for 2 weeks solid, no problems. I added 2 Xposed modules last night, swiftkey something and the one to remove the "full battery notification". I rebooted last after enabling them and the phone was fine. Charged phone last night, took it off charger (working fine) and decided to reboot it. Big mistake! It just bootlooped. It would start for 10 seconds, no wifi no data and then restart. I honestly did nothing......
I got into recovery and tried to restore my nandroid backup but same issue. Right now I am flashing 12b from the LG Flash Tool. Will that fix it? Is there another way?
Thanks for all your expertise
Tried to use the LG Flash Tool and it didn't work. Anyone got any ideas how to get my phone to stay working? It boots, for 10 seconds then reboots
If you think it's something to do with xposed why not flash the xposed disabler zip in recovery? Also have you tried a simple wipe of cache and dalvik?

I finally got the Flash tool to work and got 11a loaded on. So now I am fully stock and unrooted. But, the phone keeps rebooting. Doesn't make any sense. Anyone have any ideas?

I have a similar problem when restart the phone gets in bootloop. when the phone is operating normally burst without rebooting or any other problems. I'm all factory on it's still 802 10b and does not offer me the option to update the phone. I think it's a software error I have a warranty but I can not wait 30 days to fix my phone
I hope you understand this is a google translate

Any luck fixing this? I Have the exact same issue with my ls980(Sprint Variant). I've flashed multiple roms, kernels, and radios with no luck. Used LG Flash tool and it always fails at 94%( when it reboots the phone). However, my phone does say unrooted afterwards. I've also tried wiping all data/ factory reset. No luck.... The phone comes on and doesn't recognize any touch for a long time. Finally, it unlocks, and reboots minutes later. No apps or widgets work. The phone only stays on for so long because I turned on the stay always awake option in developer options. Any help would be greatly appreciated!

Unfortunately, I did not find a solution. Amazingly, the only rom that would load was Madallus so that is what I am running. You could try that and see if it will load.

problem i my GT-I9505

Hello guys um haing a problem in my device,after i nstalled lolipop from kies then my device keep restarting :'( it randomly restart
and its taking alot of time to restart :'(
if anyone can solve this problem ??
um new for this device
Is it that the S4 is constantly restarting after getting to your home screen, or is it that it's taking a long time to start? Keep in mind, if you upgraded to Android 5.x, the first boot after an install or a cache wipe will be much longer than normal. This is because of the ART compiler. The device will appear to hang, but it will then go into an optimization phase, where ART pre-compiles every app on the device. Thus, if it's taking a long time to start, the solution is to be patient, as you could be waiting ten minutes or more.

Try flashing official firmware via Odin. Give a factory data reset before and after flashing the firmware. All the best.

[Q] GT-I9505 suddenly turning off

Hi, I'm kind of desperate here and hope you guys can help me: since about 2 weeks my phone is ramdomly turning off and then it just doesn't want to turn on, does it when it wants or shows the initial Samsung Galaxy S4 logo and turns off again, I mean it just goes dark suddenly, not showing the Samsung boot animation nor anything, it just goes black. Initially it was only when I turned on the mobile data so I flashed another modem but now it is at any moment, Wi-Fi, mobile data... Even in safe mode. At first I thought it was the ROM beacuse I was in Lollipop BTU but I've changed it about a million times with full wipes/factory resets each time and the problem stays. I'm starting to think it's a hardware problem but I can't tell and I have no clue. Thank you for your help guys. I'm currently on Lollipop stock 5.0.1 I9505XXUHOE1-I9505OXXHOD2. I've cleaned cache, dalvik cache, done wipe/factory reset and nothing. Thank you guys, I'm lost here. Sometimes it just doesn't happen and it stays working fine but somtimes it doesn't. It is not related with any app that I've noticed.
If someone with more experience can help be I would deeply appreciate it, really, thanks in advance, I'm kind of about to throw it against the wall, thanks a million.
Did you try another battery? That would be my first guess.

Apparently it was a software issue, I just flashed another ROM after wipe/factory reset and it hasn't turned off, right now it's restoring from titanium. The last time it started turning off after a few days tho...

It could be caused by Knox. If you root make sure to delete Knox.

Note 4 hard brick which resolves on its own

Hi everyone
I own a galaxy note 4 n910g running 5.0.1 rooted and have installed TWRP
I have pretty much learned about rooting and everything i know from youtube and various other how to do posts
I have been facing a peculiar problem
I had over heating issues and i found that indexservice was the culprit and disabled it...did not have the issue again
I had emmc read failed error again and again - i disabled the facebook app - i did not receive the error again - i do not know how to explain that, but i feel that is an observation that i made
So now the real issue
I am unable to go into recovery mode.
If i restart the mobile the mobile behaves as if it is hard bricked- Literally no response at all
I keep pressing all the hard keys in different combinations, but nothing seems to work at all
Now Here is the interesting fact
I remove the battery for bout six hours and try restarting it - it works
But if i switch off my mobile or try to go into recovery mode - my phone just becomes a brick for about 8- 12 hours
and i have to go through the tedious process of waiting
i m really stuck here -
i am unable to go into recovery mode to flash my rom
Neither am i able to restart my phone - so i have a charger in pocket always worrying when my phone would go poof
i am sick of this
i just want to flash my rom to the stock android and be happy with it
I have been reading a lot of ways to unbrick my mobile - i am unable to find it
This has been troubling me for atleast 20 days
i really hope if someone would be kind enough to put me out of my misery
can someone help me find what is the problem with my phone
and how to fix it
Thanks guys for taking the time to read this
same here

I have an exactly same problem with my SM-N910G..
And the fact is System partition detected, recovery partition detected, boot partition detected, but All about Data or Internal Storage were UNDETECTED...
Really, both of us need some help.. :crying:
Entering Recovery mode bricks phone for 8 hours? Feeling sorry for you guys. But i don't understand why phone needs 6 hours after battery is removed to come back to sense and work? Anyway, have you tried accessing the download mode, If yes just download a stock rom and flash it with odin.

Have you any suggestion whether i should "repartition" it or not??
As my internal storage and data partition weren't detected (unreadable)

Hi harishjkhv,
If you are able to reboot after 6 hours by removing the battery, then try to reboot into download mode by using any super user app.
Then try to flash the stock firmware using Odin.

I've try flashing stock MM ROM from samfirmware with repartition checked..
But before i do that, i set my phone off while battery pulled out of the phone and charged separately using universal dock charger for 3 days..
My phone successfully boot and even i use for daily gaming like before, but the problem still remains..
Sometimes my phone got freeze (ended up with SOD), and when i pulled the battery off and on again, i failed to turn my phone on..
It have to wait for at least an hour without a battery..
And sometimes it says "ddi : mmc read failed" , no boot..
EDIT : oh yeah i forgot one thing, someone on the other forum encountering the same problem and suspect the power IC or mmc itself as the culprit..
And i myself think maybe because of overheating (on me is for games) those component became improperly attached to the curcuit board,and as the result is this hardbrick issues.. Will try some experiment..
I'll post here the result..
Its a software issue. I had the exact same issue with my T-Mobile version SM-N910T. I was able to resolve it by using ODIN to install the stock EPE3 along with the modem of COD6. After the phone restarted I placed the phone in download mode again and from there went on ODIN to install the EPE3 modem. After the phone restarts it should boot straight to the home screen.
Thanks guys. ..
Tried a lot of things
Nothing seemed to work...
I gave my phone to the service centre and they replaced my mother board
Cost me a lot. ..but still note 4 is worth it
Thank you guys for taking the time to help me and for your inputs

Do by a lot experiments, I've got some result that the Chips is already in the verge of death..
So replacing motherboard is the only solution for now, if someone having a same problem..
But, I hope no one encountering this problem anymore..

Constant Rebooting

Hi all,
My wife's S7 Edge (SM-G935F) was updated a couple of days ago, and now the phone constantly reboots (not sure if related).
I have tried factory resetting, wiping cache in recovery, and still the same thing. I have managed to get it to turn on, but it still reboots shortly after. Mostly it doesn't even start, just goes into boot-loop
Not rooted, and in great condition.
Any ideas what to try?
Thanks

Have you tried booting into safe mode?
It's strange that an update would cause this however you could try flashing the update manually again or downgrading to what it had before using Odin

Thanks, yes tried safe mode, still the reboots... Ill maybe try flashing like you suggest

Install Smart Switch on PC.
Connect to PC and perform recovery install.
Still no luck , return your phone to Samsung service center for repair under warranty.

Unfortunately Smart Switch said unable to do on my phone
I do have insurance, but it's the last time I can claim for a year, and it costs the excess, or I have to wait several weeks if I send to Samsung
Any other ideas?

Yeah even on emergency recovery.. Looks like I'll have to claim on insurance
Same issue right here, i tried almost everything... Flashed the new BRO firmware, and i still getting random resets.
i can't even get pass the first Google config in safe mode.
Same problem. Constant re-booting. Impossible to unlock, as no keyboard appears with the unlock screen. Impossible to turn off.
Try to downgrade firmware using odin to stock marshmallow , but first remember to have usb debugging checked in developer options , if they can't be accessed, the only option remains is smart switch , if that too couldn't help , then send it back for repairs.
have also got the same problem since the last OTA update from Samsung. My current version is G935FXXU1DQD7. I'm just downloading the later version DQHF to see if that resolves the issue.
A short term fix is to delete the cache from the system menu (when powering on with power button, home button and volume up button). It sometimes takes me 3 attempts to get into this menu to do the cache delete. After I have deleted the cache I can use the phone again, but it sometimes crashes and starts the boot loop when using certain apps.
I had this once even after fresh flash.
I deleted the cache when booting up.
Then factory reset when booting up..
Then when done i could flash it and solved it for me.
