[TUT] Port CDMA roms to your GSM

---

Hello XDA-members!

After I've got some positive feedback in the Evo 3D general section, I will explain how I got the Evo 3D CDMA rom working on my GSM Evo 3D.

First of all I'd like to thank the warm team for figuring out what the exact differences are between the CDMA & GSM roms. Also thanks aamikam for making a hybrid CDMA/GSM rom, I've looked at this rom to find out what files to replace.


Let's get to work!

At the bottom of this post I've posted a download link to a PDF file which contains the file structure of the "shooteru" folder in the "MikRunny v1.02" rom. You will need this to find out which files you need to replace; feel free to mirror it.
Once you open the PDF file you will see a list of folders with files in it. Those are the files YOU need to replace with the files of a GSM rom. Make sure you use files of the same version of android, if the CDMA rom is android 2.3.4 with HTC Sense, use GSM files of android 2.3.4 with HTC Sense. If the CDMA rom is AOSP android 4.0.1, use GSM files of android 4.0.1, you get the point I hope...

What I did to port the CDMA Android Revolution rom to the GSM:
1. Download the CDMA Android Revolution rom & download a android 2.3.4 rom with HTC Sense, in my case LeeDroid
2. Look at the file structure, and take all the files listed there from the LeeDroid rom, and replace the files in the CDMA Android Revolution rom. (If some files listed don't exist, don't worry just skip them)
3. Replace the boot.img(kernel) with the kernel of LeeDroid.
4. Compare the updater-scripts. (Check the blocks they format and change if needed)
5. Flash your ported rom, and see if it works!

This is all I did with the Android Revolution rom, and most of the hardware seems to be working!! I will post a download to the rom ported by me at the bottom of this post. All credits go to Android Revolution for this rom!!!

Of course not everything works, as the rom I ported still had the CDMA settings.apk I couldn't change the APN's so I didn't have a data connection. It also didn't see my wpa2 wifi network. These are things that you have to sort out, some things will work at once, others won't.

I would also like to ask everyone who has achieved to successfully port a rom to our Evo 3D GSM to make a thread in the development section and upload your rom so everyone can enjoy it! This will also come in handy when solving problems, write down the bugs you found, and all the members will try to look for fixes or have fixed your problems already! That's why we are a community don't keep it for yourself, share it!

Goodluck everyone!

Merging the GSM & CDMA forums

My response to this was

With this method roms boot, and most of the hardware works, but if you want a data connection, you will need the GSM settings.apk app to add APN's and such. I think it's only a matter of dropping the right APK files in /system/app/ but it's pretty important.

And pulser_g2 gave some interesting advice at how we could solve this problem

Successful ports

Yes! We have our first port from the CDMA Evo 3D posted on our GSM forums!!

whoaaa, now this is amazing!!

This is interesting, well done to the person who figured this out.

Maybe a change log of whats working and whats not, if it's just mobile data and all your have to do is change the apn's then that's a small price to pay.

Thanks for this, i was about to give up on the EVO.

The warm team figured out what files were different, I found out which files through aamikam's rom, and I tried it on a CDMA rom and it worked.

Also I think the mobile data is very simple: replace settings.apk, try it out yourself, I'm going to a party tonight and have to show of my fully working Evo 3D, so I can't try it out rightnow :P but feel free to do it!

So we can now port a FULL working(camera) cdma miui rom to Gsm?? Or only sens roms??

I'd say yes, try it out yourself

Will give it a whirl later on, hopefully i can port it successfully, i think the US version of this phone has had major attention compared to the GSM version, shame really as we need some good rom's.

That's why I tried out to port a rom from the CDMA to the GSM, and it worked out great! Now wait for more people to try it, and let the GSM forums rock ^^

Sounds good m8, looking forward to it.

Thanks a Google
