Hello everybody!!!

I repaire and flash mobile phones trough JTAG port. In some modeles, for example Samsung X720, X520, X430 there are TDO, TDI, TMS, TRST, TCK and TMODE pins set. I connecting to JTAG, put TMODE pin down and everythig woking correct. In Kyocera SE47 TMODE pin absent, but everything work right. In such models such Samsung V500 or E250 TMODE absent too, but when I connect to mobile JTAG don't work, as if I couldn't turned on TestMode (Setted by TMODE).

Please, help me how connect to Samsung E250 (for example) using JTAG if there is no TMODE pin

E250 uses MSM5500 chip others phones use MSM5100 and MSM5000

For flash programming I'am using OCDemon Flash Programmer (Macraigor) and Wiggler cable

Thanks Zaihtam !!!

But I haven't MSM5500 datasheet therefore I don't know where is located pin b17. Pleeassse, show me on picture which attached to post

Zaihtam · 03-04-2006, 07:38

the dot sign on the IC indicates the pin A1

the number is horizontal and the alphbetic is vertical.

so to find the pin b17 in your attached pic will be:

start counting from lower right (where the dot) = A1
count 17 to left. it will be the pin A17, then move upwards 1 count will be the pin B17. that's it.

Good Luck...
