After some researching and testing some installations, got the MIUI working on my Y300-0100.
These are the steps I made, for the installation.
I hope they are useful.
These are not cooked roms but as usual, I'm not responsible for any malfunction, this may cause to your phone.
Clear cache, data, dalvik
Format cache, cust, date, system
Install ROM (either versions)
Validate if the 3g is functional
Install baseband_chino (to be able to end calls)
Validating that is functional
In both roms, could end calls, and had 3g and google play.
Both roms are in chines or english.
