Try holding the power button until it powers down (more than ten seconds). You've booted into download mode. Once powered down, plug it into the charger and leave it alone for a few hours. Then attempt boot. Let me know what happens.

My Samsung i997 infuse 4 Here's a problem I help me please. Warning! A custom OS can cause critical problem in phone and installed applications. If you want to download a custom OS, press the volume up key.

sergey,

It's volume up, not down. Volume down is for installing custom roms. Hold volume up, home, and power.

You want to press VOLUME UP, power and home buttons. Hold until you see Samsung then release. You are booting up in download mode by mistake.

it is a custom operating system. There are developers who take samsungs software and rewrite it the way they like it. Or they take stock Android and load it to the device with some modifications... These custom OS's are called custom ROMs by tech community

This is exactly what happened to me. I can't turn on my samsung galaxy ace duos. Whenever I press the power button, it starts and keep freezing at the Samsung screen. A few minutes before this happened, I have downloaded a few fonts from the internet. Is it possible that this problem may due to the downloaded applications? Then what should I do? I tried to press the vol key + power key and it says that I need to download the custom OS. I am afraid that if I download this thing the phone will still be just the same. Or.... getting worse (lose all the memory) Now, I cant start my phone anymore. I just cant live without it :((

This is the problem i have with my phone:/

I have a galaxy tab 4 sm-t230nu and my little boy set a pass code on it and now we cant get on the tab anymore. oh and I already tried pressing the power vol up key and home button but it would just turn on and go straight to the enter pin screen. so I tried the home key vol up key and power button and then it took me to a whole different menu it gave me the warning and says if you wan to download a custom OS press the vol up button to continue so i pressed the vol up button and it took me to a different screen where it shows the android and says its downloading but there is nothing happening I left it alone for about a hour or so and was still on the same screen. I could really use some help with this please!!!

You have to press the volume up button and the home button at the same time. THEN it will take you to the sytemm recovery then you press reboot now and it will reboot your tab then no pascode will be on it

Hi, I had the same problem with my S4. Whenever the phone goes off and I try to turn it back on the annoying 'Warning' Custom os comes on and I couldn't turn my phone on.

I read a few articles and discovered that it has to do with your volume button. I dropped my phone a few days ago and read that if the volume button is stuck that this happens. So I went to the kitchen and go a sharp knife, put the blade to the side of the volume button and pulled it up on both ends, to my amazement, the phone turned on!!! (make sure its plugged in because whilst that warning is on the phone doesn't charge)

Now I have to go and get my volume button looked at because it is a stuck volume key that causes this. It must be a secret sequence that the phone companies use to change an os. I also read that Knox program can cause it, nevertheless, the volume button release worked.

Hope that helps.
