Hacking M3 lite Chinese problem

[houba]

hi,

i'm currently looking for firmware updagcsd.b17 until updagcsd.b27...anyone know where can i get these firmware? because on Gbalpha.com i cannot get them.

the problem is that i have the chinese version of the M3 lite...i tryed the firmware updagcsd.b15 but now i cant upgrade to the latest...the firmware updagcsd.b15 is working but i cant play the latest game....the firmware updagcsd.b16 is working but it's stuck on a blank screen after the flashing....and if i try version updagcsd.b28 or above it is denied....version updagcsd.eXX or updagcsd.cXX is denied too...

thx if anyone gat teh same problem and the answer...
