[Q] "Emergency calls only" after RUU downgrade, root, Cyanogen 6.1 install

---

Hello,

I've just rooted my Legend for the first time. To do this, I downgraded to 1.31 via RUU, then rooted using the Modaco guide.

After the RUU downgrade, I noticed that the phone said "Emergency Calls Only". Being a complete noob, I continued along with the rooting process figuring that the root flash and later mod flash might fix the problem.

After the root, I still had emergency service only. Being excited that the root worked, I went ahead and installer Rom Manager, rebooted into Clockworkmod Recovery and installed Cyanogen 6.1.

Still "emergency calls only".

I looked in Network Operators to see if my provider (Bell Canada) was visible. Sure enough, it was there. I tried to join the mobile network but the device just sits there spinning until it times out. I set the correct APN settings, but of course that didn't help - I basic GSM service doesn't work, let alone 3G.

I then found an app called Secret Settings, which gives access to a bunch of nifty hidden configuration options. I worked my way through each of the preferred network types. None of them worked.

I assume that this has something to do with the radio firmware flashed during the downgrade, although it looked like radio was also flashed during root.

So here I sit with a fancy WiFi-only device that used to be a phone. Can this be fixed? What are my options?

Please help a very technical but new-to-android-modding noob out. Thanks in advance!

Well, I seem to have fixed my own problem. Awesome!

Bell Canada HTC Legend users - if you've downgraded, rooted and are finding you have no service, or emergency only service...

1. Download "Secret Setting" from the market.
2. Tap Phone Information
3. Scroll down to "Set preferred network type"
4. Select "GSM/CDMA auto (PRL)"
5. Exit to the home screen
6. In your phone's Settings menu, select Wireless and Networks
7. Select Mobile Networks -> Network Operators
8. Make sure you're connected to Bell
9. Reboot

Dial *#*#4636#*#* on your Phone, it does the same thing as "Secret Settings" and doesn't require you to install anything.

It's been listed a number of times on the forums. You also don't need to reboot to change to GSM/CDMA auto PRL, although you probably want to select WCDMA only.
