    Doubt
    Hello, how are you, well, I have doubts because I want to do the reset to "improve" let's say the performance of my mobile since it is quite loaded. The question I have is, is there something that harms doing the reset? By this I mean will it do any damage to my phone? I know in performance or being able to open apps and that. Thanks

    [quote name=”Ana Te.”]Thanks for the info. However, now the cell phone has on the screen:
    Odin Fashion

    Custom Binary Download: No
    Current Binary: Samsung Official
    System Status: Official
    Downloding…do not turn off the target!!

    However, it's like 12 hours old. Is this normal?[/quote]

    is that the normal procedure is to press the volume button on top of the home and the power button... and when the samsumg logo appears with the model, you release the buttons and it will enter the recovery mode and that is where you choose the option you want

    I have a samsung s111 model gt-9300 and it is not the same as many that I know or have seen. It does not give me the option to reset it, nor do several functions appear in the menu. the camera stopped working. I don't know if there is any program to reset it with the computer. I need help. I live in Costa Rica and the technicians charge dearly. just to reset it they charge me more than $40.

    If you press the left touch (when it lights up) when restarting, safe mode is activated and I suppose k will also be deactivated.

    Hello! It has worked well for me, it has been as when I opened it, although I had to make some configurations that the seller had made... And that's where I'm going: the seller mentioned some things to me about «activating it to be able to call», «entering the rut, that it is necessary” (and I gave it to him then and he did it)… I wanted to know if those things, now that I reset it, I will have to do them myself, or if they are exclusive to the company Chip and then they were not affected by the reset… Or is it that the chip itself is affected by resetting? Can there be problems after resetting it?… Well, thank you very much.

    Hello migueltriny, the same thing happened to me, I restarted it by pressing the volume keys + the power key and the one on the bottom, you will enter a blue screen, I chose option 3, the equipment will remain original from the factory, that if you are going to lose everything you downloaded, but that is the only way I found the problem, I took out the sd memory and the chip just in case and it stayed as before. HOPE THIS CAN HELP YOU!!!!
