Hacking New M3i Zero not working and error message

[nuffsaid]

Just bought 2 M3i Zero for my nephews, and did all the steps on both exactly the same.

Put the F_core file and the system folder on the sd card.

But when I connect the M3i Zero to the PC via the cable, the first turned out ok, but the second doesn't work.
When I connect it to the PC, it just starts blinking faster than normal and doesn't stop, only if I disconnect the cable.

And when I try it on the DSi I get an error message:

"An error as ocurred.
Press and hold the POWER Button to turn the system off.
Please refer to the Nintendo DSi Operations Manual for details."

Anyone knows what it could be?
Thanks in advance

is your DSi 1.4u

no, it's 1.3E
and the other M3i works so the problem is not on the DSi

It is possible its just a bad Card .3% fail rate did you try the sd from other in it

I tried both sd's on the working M3 and it was ok

did the same with the other one and keep getting the error message

I bought them from a website in spain (I'm from Portugal) discoazul.com
already bought an M3 Real from them and it's been working well for a year now
