Urgent Need Cable for MPEG4 P888i - GSM-Forum

DualSimCell · 04-11-2008, 16:19

Hey Guys,
I just bought an Infinity Box and set of cables that were recommended for Chinese Phones. I bought these things specifically to repair a number of Chinese MPEG4 P888i handsets that I have that keeps switching on and off when the sim cards are placed in the phone.
Sadly, I did not get a cable to fit this phone in the 60+ cables that i have.
Can someone help me locate this cable, or is it possible, that I can take one of the data cables for the phone and add an RJ45 jack to it and work it that way?

what's conector type??
try locate GND on it
check what's CPU type inside phone (maybe it's Spreadtrum CPU)

hello!

yes, start from opening phone and checking which MCU it is based.
you had to buy our pinout finder, this would be bettter than 60 cables.
but as long as you didnt- we will advice you how to make own cable.
just need to find pinout.
but i repeat- start from checking MCU type

Hi,
Don't mean to sound daft, but what's the MCU?...is it labelled?...do I have to remove the housing?

InfinityHelp · 04-13-2008, 13:34

hello!

MCU is main control unit, processor in other words.
yes, to see it's type you need completly disassemble phone

hello!

email recieve, this is double MCU phone.
poinout you can find by yourself if you measure voltage on all phone pins.
Data lines will show 2,7-2,9 volts

Still brings me back to not having a cable for it, how can I make one?
