so if i did that using the t689 cable ...then it uses the 18 pin sams a300 connector

hello!

i think worth to start from searching second CPU pinout for t689 18pin phone.
assemble cable and try. Please note: second CPU booting is very long.
to get communication with it you must hold power button arround 1minute.
while this time first MCU will start, and phone become On.
but you still must keep button pressed, then, after some time you will boot second MCU.

i know i have to wait for 2nd cpu to boot,i solved many t689 , but those models have the pionut for the second cpu under the imei sticker

jokkergsm · 02-21-2008, 14:24

so ...where do i find pinout for this model ?

10x!

InfinityHelp · 02-21-2008, 21:04

i have a pb after formating the 1st cpu ...(i haven`t noticed that before )...the pad is not working properly...(ex: if i press an icon ...the icon above it starts )...i did a backup an it`s in the same state as before ...

anyway...i have a second phone ...and this one has the same problem ...

also when it makes backup ...it allways says that the eep area adress is not standard ...

what to do ??

hello!

i think worth to search for touch screen calibation option

cdma-india · 04-01-2008, 20:55

to find 2nd cpu pinout just use reverse way its always works and fast also

jokkergsm · 04-02-2008, 12:54

pen calibration works

)...jeeez i`m so dumb :P

i thought it is because it has mt6226 cpu inside ...and i sent u full backup of it :P

10x!

Second cpu pinout for T689 also work for HT508 second cpu

1,2=GND
10=Rx B
6=Tx B
