[Q] Help!

Hi guys , i currently have a Samsung Galaxy S4-I9505 (un-rooted) . Just a few days back , it started to shut down by itself for no reason and when i try to on it again it will get stuck in the "Samsung Galaxy S4" boot up screen and goes blank again . I have tried to restart it many times in safe mode and tried to wiping the cache but it goes blank as soon as i try to press something . Another solution i saw was to re-flash the firmware using KIES , but i can't even get it to work (no LED light when plugged in to charger or the computer ) . I did call Samsung service hotline and they think that there is a problem with the motherboard so they suggest i send it to get checked . So , any suggestion on how to fix this ? Any help would be greatly appreciated . Thanks !

Hi mate,
First thing i would do is a backup of personal data and apps
Check if any of the pushbuttons is stuck , specially the power button
Can you go to recovery , can you go to download mode?
Try first a factory reset and see if it help,if not i would reflash firmware with Odin...BUT if it is in warranty still take it to them and have it fix

Hi there , is there a way for me to do backup without turning the phone on ? since currently i can't turn my phone on .
I do not think that any buttons are stuck seems fine on the outside, but after going through some youtube videos i think there might be something stuck internally ? so maybe i will take it out and try to see if it works .
I can get to the page where it shows recovery and download mode sometimes but if i press a button to select an option it will go blank straight away .
Sadly it is not under warranty anymore , maybe i will open it up and give it a try first .
Thanks for the reply !

Hi ,
unfortunately no you need the phone to be on.
Even if the buttons look fine they may be stock , if you know how open the phone and try to wiggle them

i just downloaded and installed the android 10 system update from the ASUS download centre and after installation completed the phone worked for a while and then it suddenly got locked and after a sec it started showing black screen and the navigation buttons and status bar are flashing (popping out and going in) and it occasionally also shows the lock screen for a brief moment. I have tried going into safe mode and this issue still happens. is there a way i can fix this without hard resetting the phone? i was editing the quick access menu options just before the phone got locked if that helps. please help. u can find a video of the phone in attachments or here
