Hi to everyone 1st excuse me for my poor english i explain my problem: i've the old version of M3i zero, i've upgraded to the last version of the core (http://filetrip.net/f24219-M3i-Zero-Core-1-7-2.html) and i've tried with sakura (http://filetrip.net/f4374-M3-Sakura-TouchPod-for-M3-RealM3i-Zero-1-49X-3rd-4-9X.html) and the official gui (when i use this, on the menu is present (M3 real and not M3i zero.. it's normal?) after upgrading the core it's all ok, the games plays well but, when i turn off the console or i go to the home screen and i push on Nemo, appears "error, turn off the console bla bla". if i redo the upgrade it goes but only for 1time... do you have some ideas to help me? i've a 3ds (FW 1.1.0-1E) but i've verified the same problem on a dsi of a friend of mine. i've tried also a kingston and a bulk SD with same results (2GB) thank you!
