Next 8800 arte rm-233 chinese pinout needed - GSM-Forum

seba6250 · 12-02-2009, 22:15

so after hard working with my pin finder all is done and i/m going to translate second chinese phone, first was vertu

problem is that vertu had rx/tx in connector and also on PCB marked like tx/rx/gnd so i solder wire and wasn't problem with connect!

in this time i have 8800 based on MT6226ba with micro usb connector and 13testpoints on PCB.
i try with cut original micro USB cable from nokia and solder four wire to free wire from pinfinder cable ,but nothing.
next step was soldering wire to this testpoint ,first like in picture 8 on right ,next 5 on left but nothing.

i also used multimeter and 1st 2nd pin is 2,7 2,8 and i think it is rx tx but nothing:/ What about GND i must connect to PCB?? in vertu i only connected rx/tx and everything worked....
or maybe i must connect 13 on one time?

i atached photo
please help me

VERTU PCB for example

Hello,

it is need to connect 3 wires: Rx/Tx/Gnd
You can connect GND wire f.e. to "-" battery contact.

ok how about this chip mt6226?
i have pcb nokia 8900 with chip mt6225 every 20pieces connect without problem, but now i have carbon 8800 with mt6226 and no solution i tried everything and nothing:/

InfinityHelp · 12-07-2009, 17:56

hello!

i have made such phone, as PCB on your picture.
I rememmber for sure, that this phone do not keep tx/rx in system connector and i found pinout by multimeter

seba6250 · 12-07-2009, 19:40

in first pcb i try with multimeter and i found pins with probably rx/tx it takes me about 30second...i connected phone with solder wire to adapter and another 30secon and pinfinder found pins

great-->(PCB no.1)
.....i took another pcb like in a second photo and do the same took multimeter,found pins,solder wire and connect to adapter, and nothing...in this second pcb i have 4pins with OK voltage but really in zoom there is mirror-image with resistor beetwen. i have one more thing first pcb with mt6225 when i connected to +/- crocodile can turn ON for 2second or only white blink.... but this second pcb can't turn on i'll tell your more this pcb (mt6226) with battery need 6second to turn on. this is not normall but i have 20pieces to do

maybe i must use custom mode independent cpu with battery??

InfinityHelp · 12-07-2009, 23:56

hello!

yes, try CPU independent mode on Powered On phone.
dont forget to connect black wire to some grounded phone part

seba6250 · 12-09-2009, 21:54

hi
i found pinout in cpu independent mode thanks

seba6250 · 12-13-2009, 21:48

but i have now simillar 8800 based on mt6226 with pins exactly like on my last photo ,4pins which show on multimeter voltage between 2,7-2,8.
i can't connect and i try all ways to find it

i connected wire to pins 1-2,1-3,1-4,2-3,2-4...etc...but on the picture this pins which are connected by resistor also are connected by hide track.(maybe some short)..look on the picture

i'm stupid now... i spend 7days/8hour and nothing...i have your box only 2 weeks but now i have on my acount 20phones connected

it is possible that rx/tx is somewhere on pcb on resistor?because there isn't another pins on pcb...phone connector micro usb

InfinityHelp · 12-13-2009, 22:38

hello!

do you have ground wire connected all the time?
without box GND (pin8) connected to phone grounded part- no point to search communication

seba6250 · 12-13-2009, 23:21

yes i have all time grounded wire from com and also grounded black crocodile from rj-45 , all grounded to microusb connector shield.... pin 8 is GND?

InfinityHelp · 12-14-2009, 14:19

hello!

i am sure i've done this type of phone.
and pinout was those pins with resistors

seba6250 · 12-17-2009, 21:30

hi
i'm stupid now....because two of my friend try to find pins in this 8800 and nothing, there is a lot of points with votage 2,7-2,9 on pcb so i have question if i connect two pins and one of them is connected correct for example rx and second is wrong connected, program pinfinder show me that RX is 8 but TX isn't find????

InfinityHelp · 12-19-2009, 14:26

hello!

no, pinfinder can find both pins at once or will not find anything.
it can not detect one of Tx or Rx

seba6250 · 12-19-2009, 23:56

it is possible thta phone is blocked?
i try with all points on pcb which look like rx,tx and nothing! all resistor all points ,connector ,lcd connector ,all!! i have many chines phone in my ofoce from sciphone to leady and all working!! :/phone can't turn on on infinity cable but in cpu indenpendet mode can't find pins:/
please help me!
