and so, I'm back here, with a problem, because I lent my elder brother my i9003 after using my i4 for quite some time and for some bit of ignorant stupidity (forgive me), he got my phone wet. Submerged for a few minutes, in fact.
Long story short, his friends dragged him to a pool to pose for a picture. Forgot about the phone, and so walah, the LCD got water in it, and the home button died after a day.
Now, the camera is not working, with a pop up appearing with the message "Camera failed". I am aware of a present solution of reflashing the whole phone again, however, even though it is my phone, my brother is using it (heck yes for respect -.-, stupid bro). As much as a stupid question, how do I access recovery mode and download mode without a PC, perhaps and without the home button? Luckily, I have installed 14-status toggle, so I can access it, but how then can I access it once I have reflashed a new ROM?
