I have flashed ATT TW AND AOSP roms for my Tmobile out of the box and it works. I then change the build.prop with root explorer.

Going to give this a try this weekend. It's a dumb question but could I use this to say port a Sprint ROM to my AT&T phone ? Just a straight port over but just changing the things you list here ?

I can't say for sure, but it should work just fine.

Though I must admit, Sprint is the worst choice you could make for your first port attempt. You could have problems with both libs and kernels.

And I still haven't figured out how to get MMS working on my Sprint port. :mad:

hrmmm Verizon doesnt seem like a good port either and most tmo are fairly compatible already. I'll keep searching I guess

Is there any way of porting anything from the international i9300 to the AT&T i747 using a similar method as found in the original post?
I understand the processor and radio differences.

There is going to be a lot more than is listed here for that... I doubt its really possible. Kind like you can't easily port a i777 ROM to a skyrocket

It will take much more than what is listed in the OP. I am not sure I have ever seen a ROM ported from Europe to the US (or the other way around).

As you mentioned, the processor and radios are different, but so are the system partitions. Anything is possible, but I think that would be a huge amount of work.

If you try this please be very careful. Many, many users have bricked their devices flashing a ROM from across the pond.

Hey all, I was hoping to get some assistance on an issue that myself and stratatak7 have been having. We're trying to port the Intergalactic ROM over to VZW. Following this guide, I was able to get it to boot and everything is functional including calling and texts, but we cannot get any mobile data. We've gone as far as replacing the kernel with a vzw kernel and replacing the modules in Intergalactic with modules from a vzw rom but mobile data refuses to work. I would be grateful for any suggestions because it seems that we are at a loss. Thanks :)

Just to be safe can you screenshot your APN settings please to make sure they set correctly. Settings>mobile networks>access point names. It should take two screenshots to get it all.

OK, I apologize for having to ask this, but are you sure you followed all the steps correctly? I have to ask because my ROMs are the same version Intergalactic. Also, are you sure you grabbed the files from a VZW BLK3 ROM? Libs are the most important for data.

I have attached the files I use for my VZW port. I would change nothing except the ROM name in the build.prop for now and see how that goes. The eri.xml is compiled, so you can just add the file to framework-res with 7Zip. I started adding the csc files recently, but I don't think they really make a difference.

All the files were pulled from k3 ROMs yes. I've done the steps correctly to my knowledge, but I'll try again with your files when I get home and get back to you all. Thanks again.

Fantastic news; Using your files worked. I'm up and running with data and everything else seems to be working just fine. Thanks a lot for the help. Now i'm just gonna tinker around and find out where I went wrong. :p

When I flash a att rom on my t999 do I need to flash a tmo modem or just change the build prop and kernel of choice?

For your own personal use you should be able to get by with just changing your build.prop. Maybe the apn if you run in to any data problems. You should not need to flash a kernel or radio.

Ok well I'm working on getting Intergalactic to work on my T999. I guess i have some file editing to do.

    This guide has already been used twice (and possibly four times) to break xda rules. I will not enable that.

    Sorry everyone. Thread closed.

    What rom have you tried?

    I tried to flash something and got Status 7.

    Status 7 error while flashing usually means there is an error in your updater-script.

    I think Verizon would be a good choice.
