Pinouts for B889:
2 = RX_B
3= RX_A
4= TX_B
5 = TX_A
6 = GND
I have also problems with my B889 slave CPU IMEI, have tried to get help from multibox team, but nothing still going with only one SIM :mad:
Maybe going to scrap whole multibox and buy an Infinitybox, they seem to have better support.
what is this pinout for ? both cpu ? i know that i have to repair imei on second CPU to make it work but i can t connect the phone !!!
any help chinese experts ??

Hi, i am so new to the forum. As far as i know for this model (b889) no need to use any box. They had a program which they can use to access the machine via USB cables. I dont know where can u get it but i saw it and used it in China, but unfortunately i cant share it. company rulez :( If possible can somebody show me how to reach the phone via boxes?
Cheers!
French language to this model please !
