Problems when I'm flashing...

[AdyBOSS]

Hola!
I have a problem when I try to flash a 6210 phone.
I have upgaded the software in my 6210 from a erlier version to 5.36 version. But wheh I've tried to set FAID, the programs I've tried cannot init. the phone. The phone is starting but I still set FAID because is reseting...
More than this, when I'm trying read the phone, it cannot be done because the flash program (NOKIA DCT3 Flasher by rolis v. 4.78 build 006) get me "Whait for boot counter accept (Phone TX=High)".
If I try to write get me the same screen and after that get me "Timeout (check cable or mobile contacts)".
This is only for this updated phone, because I've tried with another 6210 and all is working perfectly.
Can anyone tell me what is the problem and if can be repaired this...
Thanx.

I've tried m8, but... nothig was happened.
Where can be the problem? The communication witb MBus cable is made on two pins (GND and MBus). So, if don't work, must be from one of this two pins. But the rolis program tell me that TX is high and as you know TX connection is realised on another pin.
So...
