7280 RM-14 Test points - GSM-Forum

Hi there, does anyone have the pinouts for the 10 test points on the PCB especially D+/- and Bat+ ?
Thanks in anticipation.

OK I have found the pinouts but unfortunately there are no D+ or D- points. I need to connect this phone to a pc but there is no USB connection/connector. Any Ideas please?

Does bluetooth help?
if not, only with a fbus cable+interface for the program that supports that phone model and the process you're attempting to do.

I have an RM-14 Fbus cable interface which goes to an RJ45 connector. I also have an RJ45 adapter to USB but Phoenix does not see it. I do not have a "Box" but followed a site that talked about connecting Nokias to phoenix without a box. (they had a USB connector though)
The 7280 went into white screen while I was transferring music to it. I heard that this was quite a normal problem with the old firmware. I need to flash the newer RM-14 327 firmware which I have. There is no useable access (BT or Ir) to the phone only the aforesaid white screens. The Fbus connector differs from the nokia one in that it doesn't switch the battery supply. I made a short dummy sim to switch this when the connector is inserted. I guess there is no D +/- test point on the pcb as it was never intended for usb connection. I think that my only hope is to find a s/h box cheap that no-one uses anymore.
Any suggestions more than welcome.

For FW reprograming, you will really need a box! Cyclone, jaf, hwk. Don't know if infinity best bb5 will work with this model.
There is no fbus rj45 to usb.

Are you able to share a photo from the fbus cable? Never dealt with this model before so im not figuring what you mean with:

THE Nokia Flash adapter is SF-30 and has long side arms that operate a switch in the phone as if there was a sim inserted. Probably the cut down simulated sim card would not be required with a box as power would be suplied from the box.
The pivture of the SF-30 can be seen on page 11 of the 7270 service manual 3.
Cheers.
No idea where I can find a service box or someone who has one that can flash the phone for me here. It is a one off operation so no big bucks to buy one.
