[Q] Set Network xml network profile

---

Hello guys,
I have a LG E900 unlocked from Telefonica Spain and I live in Lima - Perú (southamerica), I have problems with MMS and 3G network, I can navigate on internet by EDGE but the speed is terrible.
On MFG application I can't find my mobile operator and I can't set up the network profile because my operator doesn't appear in the list
I have read that if I make a hard reset on the phone, in the first boot the Phone catch the network parameters (including MMS and 3G) from the carrier (from my SIM carrier), it's true?
Or are there any way to modify manually the xml network configuration file in order to set the correct parameters in all the fields?
I will really appreciate your help.

Thank you

All you need to do is set ADC on, and soft reset, then you are good to go. You need to go to Engineer Menu>Other Settings>Set ADC. Alternatively, you can download the network app from the LG store in the Marketplace, and it will set ADC to ON upon first time running the app...

Hope it helps.

Hi kapanak, I just tried your advice few minutes ago but the problem continue happend, I've tried with soft a hard reset and in both cases set ADC to ON doesn't work. My carrier have to send me the data in a special format or stuff like that?
Is it possible to change the parameters of xml network profile file by myself?
Just in case: what do you mean with "soft reset"? turn off and then turn on the phone?
How can I change proxy settings on this phone? In this post http://forum.xda-developers.com/showthread.php?t=843517 in the #3 it is mentioned some way to set the proxy and port settings on a samsung focus, I thinks these settings are missing on my LG Optimus 7 and that is why I can't access to 3G Network. some ideas?
Thank you for your answer

After you set ADC on, try to change sim (from another operator), restart, let it connect, and after that, insert back your sim. After restart go to settings, celular, data conection on and it should work.
Be sure if you have 3G network in your area...

Yes, I forgot to mention you need to swap SIM cards in order for the above to work. And make sure you take out the battery or you WILL short circuit the SIM, and your phone.

Thank you kapanak for your answer but It didn't work, I couldn't connect to 3G network and I still seeing the same network parameters (proxy and port) on my network xml file (throught MFG). Are there any way to modify these parameters directly on xml network file?
I guess that my carrier (Claro - Perú) is not able to send the autoconfig information in WP7 format.
Thank you

Have you tried to manually put the Claro APN? I used to do that here in Brazil and at least the 3G worked.

Try to do this:

Settings > Cellular > add apn, and then:

APN: claro.pe or wap.claro.pe (I found both on Bing)
User name: claro
Password: claro

And I think that's it.

PS.: My E900 only start to get automatic setup through ADC after I flashed my Orange-FR phone with an Open-EU ROM found here on XDA, before this, I used to manually set the APN and worked well, only the MMS was missing.
