Most probably motherboard issue and should be replaced if possible ,had same issue on s7edge with random reboots ,shutdown not turning on ect

Hi guys, regarding the restarting issue...have some “improvements” after deleting data in apps...phone and device maintenance....15 hours without restarting..fingers crossed

Hi guys....the restarts have become too much to the point the phone is unusable...its worse when the phone is on 4G/LTE...Sometimes the screen goes dark and the phone becomes unresponsive.
My effort to take to the Samsung centre for repair has been in vain...as I bought the phone overseas and the warranty is not honored here.
Any help will be appreciated...

Very strange booting problem with my samsung galaxy S5 (SM-G900F)

Hello,
I hope someone can solve this problem for me. On a day i wanted to check my phone and I saw only the logoscreen of samsung. My first reaction was to pull the battery out and put it back in. So I restarted my phone but it was not going further dan the logoscreen of samsung and always kept restarting automatically. The very strange thing is when I remove the battery for more than 15 minutes and than put the battery again in the phone and push on the power button it starts with no problems. When the phone is completely started and I restart the phone manually the problem comes back again and the screen is not going further than the logoscreen of samsung and keeps restarting all the time automatically. The phone is 2,5 years old and I used it daily
What I already tried to solve the problem:
- Reset factory settings and wipe cache partition with the "power, volume up and home button"
- Installed firmware from sammobile with odin (firmware completed but still automatically restarting at logoscreen)
- Blew the powerbutton with air
- Rooted the phone with Kingo Root
I hope someone can help me? Dont know what I can do more
Root the phone properly instead of using kingoroot

The problem with rooting is that it sometimes has to restart the phone and then I have to problem again that it is not going further than the logoscreen. How do you root? Do you have a guide?

Zenfone 5 freezes seconds after boot up or when charger is disconnected.

Hi, I'm new to the forum.
Lately I'm having this problem where my phone ALWAYS freezes right after the main screen appear (sometimes I get to mess around but it always freezes). Resetting it to factory setting sometimes fix it but if I disconnect the charger it immediately freezes and I have to reset it again. In the past it only froze when the charger was turned off but now it is freezing even on the boot screen (2nd asus logo).
WW
Unlocked Bootloader
TWRP recovery
Xposed framework latest version
Rooted
android 5.0
I saw some threads about unlocked bootloader freezing the phone but I don't know if my problem is related to it but later in the weekend I may try the "fix".
Thanks.

S7 Edge crashes and reboots at Samsung logo, hardware or not? [All Stock]

Im so lost with this, im all stock but one day my phone just freezes then bootloop, I would be able to get it work by just leaving it and let it drain itself since it will be boot looping and lock me out completely, like the power button + low volume button would not work even after 10 minutes of holding it, would not boot to download or recovery mode, just the soft touch keys light on and the blue LED.
I reflashed my ROM from sammobile yesterday but did it half-effort, just dirty flashed it but it seemed to reformatted my phone anyway, after reflashing it, everything seemed to work properly for 20 hours and then now im back to this piece of ********* boot looping...
S7 Edge
running the Australia unbranded XSA-G935FXXS1DQG4 from the branded G935FXXS1DQG5,
would flashing de-branded affect this? or this is hardware?, one thing I did that I think was a mistake is that I chose to restore from old device, can apps cause this?
the very first time this happened, I plugged it in to charge then crash and bootloop.
UPDATE:
Things I've tried,
-Booting with NO sim card and SD Card
-Wiping cache and partition then reflashing stock XSA and OPS firmwares
im convinced that this is a hardware issue and will go to Samsung.
mine does this too. crashes then gets into a bootloop at the Samsung logo. I usually try holding the lock and volume down button. I factory reset the phone once but it still keeps happening, this started happening around 4 weeks ago
Guys your Main/Mother-boards are broken.. u need to replace it, or send back to Samsung..
Damn! Crash reboot samsung logo
Damn you say broken mother board...
did this. Press vol down, power button and home key...hmmm... i think...pressed so many combos hard to tell themapart
