Hi!
Today I got a notification that there was an OTA ready. After installing the OTA my S4 keeps rebooting. It only works for 5-10 seconds and then it reboots. Not a complete reboot though, I don't have to type my pin again I just get the blue-purple ring and the samsung logo.
I've tried booting into recovery and did a factory reset but it still reboots:crying:
My S4 is the international version and it is completely stock and not rooted.
What do I do?
Thanks
EDIT: I started from scratch without importing apps and settings from google at it seems to have done the trick
Good Day Everyone...
I hope you all are fine...
Allow me to explain my story till we hit the big problem that is the hotboot/fastboot...
10 months ago, I bought Samsung Note 4 SM-N910C ... Was switching from Broken screen Note 4... I had a Nandroid backup of it... but while restoring I messed up badly as I wiped the new device IMEI that time... but I managed to find someone to fix the phone and create a backup... Now Why did I change my phone again...? Battery degrading, phone heating and of course from time to another I must restore the IMEI backup as it gets corrupted suddenly and randomly... In addition to the Note 4 Great Offer...
All 3 phones were SM-N910C, however the first 2 came as KitKat 4.4.4 and the latest phone came as Lollipop 5.0.1 ...I didn't really care much as I grabbed the Nandroid and restored it carefully... Everything works great, Until after installing Xposed... softboot / hotboot / fastboot / quickboot whatever you wish to call acts similar to REBOOT but without shutdown... This issue is Critically annoying as I play from time to another with Xposed and rebooting sometimes don't give Xposed enough time to load the modules ... In addition the SIM lock is active at every reboot and the loading TIME...
I took a backup for all my application on Titanium Backup... Preformed a clean Install of Kitkat 4.4.4 ROM on the phone and restored the applications, Hotboot remained the same... I thought perhaps Xposed is the issue... So I went to ADB command ... adb reboot fastboot ... same results ... phone keeps REBOOTING without shutdown...
How Reboot without Shutdown? Do I know the difference between Hotboot & Reboot?
Yes I do know the difference...
a Reboot would go to shutdown animation, reboot to Samsung NOTE 4 then load the BootAnimation followed by its loop till device has loaded, reboot clears all memory and reload everything, Enter SIM Lock and takes time...
a Hotboot would go immediately to BootAnimation then loop while in the background it's just refreshing the Apps and services briefly, no SIM Lock needed, it doesn't take time...
My HOTBOOT is doing same as REBOOT but skipping the Shutdown animation...
So my Question: What is wrong with my Hotboot? Is it Lollipop? Do I need to check something?
I Thank you all for your patience and reading all what I wrote whether you Answered or not...
P.S: Some Xposed apps are acting weird on this phone compared to the 2 previous Note 4 phones...

Lollipop 5.1.1 fix the "Hotboot" problem, also disable fingerprint (it's the main cause).
Next iteration of update will fix fingerprint problem.

Thank you @d4rkkn16ht for responding...
So I should Flash lollipop 5.1.1 then flash back to kitkat?
I have done many tests for hotboot via trying multipl 4.4.4e apps... 2 apps out of 6 managed to hotboot...
Xposed installer failed...
TWRP manager failed...
APM+ failed...
Fastboot failed...
Simple reboot success...
Root toolbox success...
I have Kitkat 4.4.4 on my phone... Rooted with TWRP recovery and xposed installed... Busybody is present... Selinux enforcing... What more information do I need to provide?

XPOSED is still problematic on TW odexed Lollipop ROM, so it is not recommended to install EXPOSED on your Note 4 with Lollipop.
Fingerprint causing many problem on Lollipop 5.0.1 - 5.1.1 (sudden lag, random hotboot, random apps kill), so disable fingerprint while you are on Lollipop.
Some said that COI update (5.1.1) fix fingerprint bug.

I am really getting lost...
You talk about Lollipop while I have downgraded to Kitkat... In other words, I have kitkat now on my phone... With hotboot problem...

After a few KitKat updates my phone started random hotboot too.
On lollipop 5.1.1 (COH update) it's all gone with 2 drawbacks.
Fingerprint must be off or I'll get another random hotboot+random lag.
Xposed Framework is out of the question for Stock 5.1.1 ROM.
The only way to install Xposed is to flash non a TW ROM or flash a Deodexed Stock ROM which is not my preferences as XPOSED for 5.1.1 is still in ALPHA stage.
COI update said to be the best update as it fix fingerprint bug. But COI update is still unavailable in my country.
Since no solutions were found...
I'd share mine... You need Root...
Simply use this apk:
https://play.google.com/store/apps/details?id=simple.reboot.com
Create a widget and drop it on the home screen...
This solution is temporarily until the cause is found which will likely take a lot of time...
hi guys i have an issue with my device (i9500) since i had a bad efs partition which i successfully restored from a backup.
The device works perfectly, but as soon as you lock it, and wait a few seconds, you can't unlock it anymore. Screen stays black, and the only way to get it started again is by removing the battery. Then it keeps on working perfectly, apps, games, everything is fine, as long as you don't lock it (by pressing powerbutton or auto lock)
Either then it crashes or restarts.
Things i've done already:
- Soft reset
- Hard reset + cache wiped
- tried many different roms
- fresh stock rom installed with Odin.
Problem still persists.
I've recently discovered that I don't have this problem on miui 7 running on 4.4 2. But as soon as I install flyme which is on 5.0.1 or any other lollipop rom or even stock lollipop then the phone either crashes while I'm using it or freezes at lockscreen and I can't unlock it. Please help guys cause I really wanna get back to my flyme rom on lollipop.
Hello, my galaxy started to freeze and crash 2 months ago. At first i didn't mind it because it just happens once in a while. But 3 weeks ago, the freeze and crash became more frequent up to a point that even though i'm not doing anything to the phone, it just freeze then restarts. I researched the web and found some solutions, first i've tried to reset to factory settings. i used the wipe data/factory reset in recovery mode. it said the reset is successful then i've restarted the phone and i just loops on the samsung black screen or just crashes during the welcome screen. Then i tried to reinstall the firmware using odin. first i used the 4.4.4 tar (from this forum), the odin said the flash is okay, but when the phone starts up, it just loops on the samsung black screen or just crashes during the welcome screen. so i tried using the downgrade to 4.4.2 tar (from this forum), after successfully flashing it, my phone started to boot. but after i completed the first time process and i'm updating/downloading apps, it started to freeze and crash again, this became a frequent thing again. it just freeze and crashes anytime. i've tried reflashing the 4.4.2 again using a different cord and port, but the same thing still happens. Do you guys know if there is still some way to solve this?
Note: I've got this phone from my father when i visited him in the USA (last June 2015), then when i went home (in the Philippines), i didn't unlock the phone so i it didn't have any sim card since then. is this a factor in the phone's behavior?
Thank you
Up.. hopes someone can help me with this
Update: I've tried using another battery and the situation is still the same.
Hi, I installed an update to my S7 Edge (Australia) - I think it was Feb security updates.
My phone would occasionally reboot by itself once in a while before this.
After this update, my phone crashed while making phone calls, and then it would mostly reboot itself after 3 minutes every time.
I didn't want to play around with Custom ROMs just yet, so I installed Odin and flashed the stock XSA firmware for my device.
This was successful, but now my phone still keeps rebooting while going through setup, join the wifi network, and... reboot. Or up to add your google account, Just a sec, and ..... reboot. Or gets up to "which apps do you want to sync" and then reboot.
It's also been freezing on me in recovery mode.
Is this a physical fault? Any ideas? thanks
Tried another factory wipe after flashing stock firmware?
