[Windows Phone 7 Development and Hacking] viking13:
No problem.

Please read carefully all I wrote before answer, because you might be misled by some things. I flashed and unlocked my phone many times, so please have patience to read all.

I have Vodaphone DE unbranded Trophy.

I used those two files as a start:

1- RUU_Spark_Vodafone_DE_1.09.401.08_Radio_5.51.09.06_22.23.50.09U_Signed_by_ansar

2- RUU_Spark_Vodafone_DE_1.10.162.06_Radio_5.52.09.16_22.33a.50.10U_Signed_by_ansar

Before official 7720 over Zune was available:

I flashed those two files, then I unlocked and updated my phone few times. I updated it to 7712, and then to 7720 with ISVTo7720. At the end I got latest HTC update. Everything was just fine.

After official 7720 over Zune was available:

Attempt 1:

I flashed those two files I mentioned. After initial unlock with Chevron I used U2M7720 to get to this point:

7.0.7403.0

2250.09.10908.401

5.69.09.05a_22.50.50.21U

4.6.2250.0(129185)

Notice that I haven't use U2B2 nor DoNotU2B2 to reach that point. If I haven't seen update instantly, I used disconnect trick to get it.

Phone is unlocked at that point and I can do whatever I want. Connection Setup works (even the one from original ROM).

I made a backup in this state. That was my starting point for next few attempts.

I tried to install official update named "Update for Windows Phone 7 (7.10.7720.68)", not the "Update for Windows Phone 7 for ISV beta (7720)". So I skipped U2B2 step here (at this attempt).

I started U2M7720 without any problem and Clicked on Unlock .

I connected phone and updated my phone to 7720 over Zune with official update.

ConnectionSetup was automatically started when I clicked on OK message that update is finished (this is message on my phone not in Zune). I haven't notice that at that time.

I got strange message about my carrier and restart.

You suggested that I should try with another ConenctionSetup, so I did.

Attempt 2:

I restored my phone to 7.0.7403.0 (restore point I mentioned in previous attempt). And did same thing as previous time.

This time I noticed that ConnectionSetup was started automatically.

Carrier, restart message again.

So I did 3rd attempt.

Attempt 3:

I restored my phone to 7.0.7403.0 (restore point I mentioned in previous attempt). This time I uninstalled ConnectionSetup before atempt.

I did same things as previous time.

This time I received a message that I should remove U2M7720 the same moment I clicked on OK message that update is finished.

I did another attempt.

Attempt 4:

I noticed that I haven't used U2B2 nor DoNotU2B2, so I tried that too. I did same thing as in attempt 2, but this time I clicked DoNotU2B2 before click on Unlock.

Update was successful (as every other time), but message in ConnectionSetup was still there.

In short:

I tried to use different ConenctionSetup versions (from original ROM and from market place). I tired to uninstall it and to install it again later. I tried to use DoNotU2B2 and not to use anything. I tried to use another SIM card.

No help.

I wrote all this in order to help someone with same problem like me. If I lost so many time with this, why would anyone else waste his time trying same things?

At the end I even installed another ROM (XBmod's tropy ROM) and I have exactly same problems with ConnectionSetup that I had on your ROM.

I noticed that some guys from this forum also had strange problems with ConnectonSetup (one guy revived message that he doesn't have a SIM card).

I also noticed that there is no ConnectionSetup at UK marketplace at this time.

Coincidence or something else?
