Had a problem with a W760i today, replaced broken Chsrger connector. But the unit kept turning off when trying to charge, so in the end I just connected it to Sony Ericsson service upadter, and after a few Atempts it uppdated the software. Now the unit charges and is working fine. I did try the usual srevice tool to try and re-flash the unit but it could´nt find it, or when it did it did´nt work. So this helped me today, hope it helps somebody else. But as always you do these at your own risk.

Hi

You are welcome.

I tried with Setool, and some other tools. The W760 is a strange one. Sometimes the PC could fin it and others not. The best solution for me was the SE Service update software, with a fully charged battery. But it did´take a few attempts to do, on the third attempt it worked. The connector pad area is very sensitive especially after replacing it with a new connector. I still had to apply a little pressure on the connector against the PCB to get this update to work, but only a little pressure. If you find another solution please let me know for future reference.

Yes, you are right sometimes pure hardware troubleshooting is the only way.
