    • That’s precisely what I thought. Who in the hell would have? For those guys that did, my biggest thank you’s.

  1. Hey! I have ported a ROM and it doesn’t boot. Now, I cannot enable developer options. Is there a way I can do this through build.prop?


  2. Nice work finding this out. there is also a jellybean screen when you type on Android version and a Cyanogen screen if you are using it.

  3. Hello biggest thank you to you I was tired to find debugging option after update 4.2.2 galaxy grand GT-I9082 for root it. After your help I did it thank you again.

  4. Is their a way to force usb debugging on I have a galaxy discover something happend and my settings and all apps are gone all that is currently working is email I tried to install the settings app from my duplicate phone and the phone says cant install unless directly from market.The only thing I can think of is an app that would force debugging on run from an attachment in my email.I tried backing up the rom from the duplicate phone and tried to install I get an authentication error.In any case it pretty much a brick at this points unless I can find a way to get a file manager installed or the setting if I could force usb debugging on then I could do full backup from my other phone and restore it with ease any suggestions would be great.

    • beacause the developer dont want you now about the secret because all people will be install CostumROM when now this

  5. Thanks a lot! After rooting my Samsung Sm-G3815 Galaxy Express 2 i looked like a lunatic for this option but could not find it.
