I've had my m3i for about 2 months, first month it worked flawlessly. Flashing the card, adding all applications i wanted, homebrews, music, games, all worked #1 and loaded #1 too. One day i took it out my console to add a new game and since then, it has been hell to get it to work. At first it was not too bad, i was getting the occasional white screen but restarting it a few times did the trick. But as time went by, it happened more and more often. I either get a blank screen like it is seeing there is a card but cannot read it or saying there is no card inserted. No matter what i do now, i cannot get it to load anything anymore. I have tried to format my microsd then to re-flash my card as i saw there were new files that came out. Now it flashes indefinitely, the blinking never stops. Yesterday i left it on the computer all day and it kept flashing for 8 hours straight until i came home from work and checked it. :\ I tried with F_core.DAT only, then with the core and system folder. With the new core, the old core, new system, old system, it still flashes indefinitely and i am still getting the white screen of doom... It is getting a little frustrating. I messed around with it a little bit more this morning and to my surprise, and i don't even remember what i did [insert facepalm here], it showed the M3 icon when loading the nds but when i select it to load up sakura, it went to white screen again. I updated my sakura files and now it's back to the original problem, i get the white screen or it freezes on the warning screen.. Is there anything i missed that i could try to see if it fixes it? So far i am pretty sure it is a software/flashing issue and not a faulty cart but who knows.. I have a DS Lite, not a DSi by the way. Sorry about the small novel and thanks in advance!
