Which loaded on a rom? (XWJQ4???).
What is the exact problem?
GSM network = edge/2G
UMTS = 3G/Hspa
Settings/Wireless and network/Mobile networks/Network mode --> chose WCDMA only or GSM/WCDMA (auto).
The data may not be possible to go?
-To set correct APN settings!!

The exact problem is that my phone is gsm and when i inserts sim, it says "no sim inserted". But signals are shown there.
Its android 2.3.6(XXJPZ)
Netor Mode --> GPRS (yes its gprs and not wcdma/gsm)

[Q] loss 3G [email protected]

hi,i am using milestone 3(ME863)@Hong Kong version.
after i flashed DROID3-CM9-03-28-SELFKANG, my 3g data no longer works, the signal is fine, i can make/receive calls but as for data, market/internet anything requiring a connection it just does not work unless connected to a wifi network.
Moreover, i have changed the build.prop to gsm but i still cannot use 3g data.
so how can i get back the 3g data?
(sorry for my bad english )

there's a new issue, after i pressed the USA band, my phone did not have any signal. How can i get back the signal?

Searching pays. There's this fix here. The poster uses a XT862 but has XT883's (a.k.a ME863) radio installed on it so his phone should be on the same page as yours and you can safely try this fix. There are lot of guys here using Droid 3 on GSM so you should look around a bit.
Good luck!

thx for your reply. But i still cannot get any 3g data after replaced the build.prop, i only receive the signal. However, when i changed back to stock rom, i can use 3G data and signal. Moreover, i modified the libmoto_ril.so. i can receive 3G data for a second. After that it will disconnect automatically and then it will turn on for a second again.
How can i solve the problem?

Have you updated the internet settings in the device? After flashing CM9 and if you are using GSM, you have to manually go in and set the wap settings if they are not correct on the sim card.

thx for your reply. After i flash cm9 again, i can get the signal again but the new problem is that i cannot use 3g data....

Are that all of the custom roms in this froum cannot support gsm 3g data? i changed the build.prop of all that rom but i still cannot use 3g data

There might be a solution for the 3G Data Connection.
I have a Droid 3 XT862 with the Chinese Radio (XT883 as yours i believe) and my provider is AT&T. I am running CM9 and after i used the buid.prop from this link:
http://forum.xda-developers.com/showpost.php?p=23884104&postcount=1368
3G connection worked just fine. Don't try to flash this zip file through safestrap as it won't (at least no go for my occasion). Uznip it and copy the build.prop file to sd card. Then move it to /system by using Root Explorer (so you can mount /system as RW). Before do that, rename the old build.prop to build.prop.bak so you can have a copy in case new one won't work. You must also change the permissions to the new build.prop to rw-r-r . Finally reboot your phone and see if it will work.
My phone is running CM9 with XT883 radio and my 3G is working just fine.

[Q] I Want To Flash FTF Of 4G For 3G

What Will Happen If I Flash Stock FTF Or Flashed In Recovery Of 4G ZR For My 3G ZR " D5502 " ?

It should work. YOu will have the option to use LTE in the network settings, but of course you will not really get LTE.
To be able to use 4G your antenna needs to be compatible and the c5502's antenna is only 3G.
Short of this difference in settings you shouldn't notice any changes.

Any custom ROM that allows setting cellular data and network type independently?

The stock ROM allows 4G network only on the SIM that's set for Mobile Data.
Is there any custom ROM that would make it independent? Something like setting Mobile data to SIM 1 and its network mode to 3G, and have the second SIM for voice only with 4G network.
I haven't rooted the phone yet but if there's solution to this, I'm fine with rooting and flashing custom ROM.
Thanks
