Phone Isn't Booting - Android Q&A, Help & Troubleshooting

Hello XDA
I went to settings and pressed "factory data reset". My phone turned off, and then when it was to boot, it stopped , and now I'm stuck with a red exclamation mark and "Samsung Galaxy J1 ace" in the middle.
I have tried booting into recovery mode by pressing the volume buttons and Power, but i get the same thing.
I've tried:
- Power + Volume Up
- Power + Volume Down
- Power + Volume Up + Volume Down
- Power + Home Button + Volume Up
I still get the same screen
I did try Power + Home Button + Volume Up , and i get this:
Warning!!
A custom OS can cause critical problems in phone and installed applications.
If you want to download a custom OS, press the Volume Up key. Otherwise, press the Volume Down key to cancel.
Volume Up : Continue
Volume Down : Cancel (restart phone)

Click to collapse
I pressed volume down , and then I'm back to square one with the first problem
Help is immensely appreciated .

You need to reinstall the rom..

Thanks for reply. When should I do that combination? While the phone is off or while is stuck on this screen? How long should I hold power key? Just for a second or until something happens?

3) then press volume down + volume up
4) then soft press power key
5) if ur phone is power on

Same thing, it got booted up in Android but this time it says "Safe mode" in the bottom left corner (can't remember if it said that last time).
Power off ur phone before following the above key combination and wait until the screen turns back on.
Don't understand you, but I think you should go to download mode and reinstall TWRP.

Hi , it should work with Vol + and power buttons , maybe you didn't do it correctly or for you is another way .
You can try this :
1. Make sure your device is off
2. Now press together Vol + and Power button at the same time , it will vibrate but don't release keys , once logo appear release both keys and fast press just Vol - button several times until you see recovery menu if that doesn't worl try the same think but with VOl - button , and second key is now VOl + to press several times.

I don't know try to hold long Vol + and power buton just hold like that and one you see logo release just power key, if that doesn't work probably your buttons is not working properly.
