Hello, I have a SPH-L900 since 2 years ago, I did the gsm mod and it worked perfectly, already bricked it sometimes and always got it back to work but I never knew the difference between the roms of SPH-L900 and N7100. Can anyone explain me the differences and maybe if you know it, what is needed to port a rom from N7100 to SPH-L900?
well i don't have to much experience with the N7100 but I've been building a lot with t0lte/l900. The first thing ill say is its not so much about porting the rom from n7100 as it is porting it too l900.
so with that said its hard to know were to start as i don't know how much experience you have. also since you use a gsm mod do you still use l900 roms or t0lte?
wiki.cyanogenmod.org/w/Build_for_l900
make sure you pay attention to the "Prepare the device-specific code" section
take a look at you cm.dependencies file to get a good idea of what repos your phone uses to build
github.com/CyanogenMod/android_device_samsung_l900/blob/cm-12.1/cm.dependencies
so back to about porting roms to the l900 as long as its a cyanogenmod based rom its probably easier to start from your respective cm repo in are case the l900 repo then to try and convert the n7100 repo.
github.com/CyanogenMod/android_device_samsung_l900/tree/cm-12.1
Yeah, I'm still using L900 roms but there was one rom I've seen that asked for some kind of change in the files so it would match the N7100 roms. Never tried to do that. I'm not experient at building roms, I have some experience in programming since I'm an IT student. I was asking that because I wanted to try to port some roms but the day after I posted this I managed to break the digitizer while exchanging the outer glass, so no good now. Thanks for your help ^^

I had a thought today while at work and wanted to try my hand at porting over the LiquidMetal rom from the Acer over to our phones. Now, I know this isn't something thats easy to do (especially if you've never done any dev work or port a rom over before, like me.), and I know that if I just wanted to get the rom to boot, I can just swap the kernel's out and the rom should at least boot.
I want to (hopefully) use jermaine151's rom over at the Droid Incred. forum as the rom to port over, but, I still havent asked him as this is still just an idea and I wanted some insight as to what Im doing to need to make this happen.
I know Im going to have to port over a lot of lib files and drivers for wifi and such, so, my question is what would I need so I can at least get this rom up and running?
Also, Im downloading the Source Code for LiquidMetal as I type this, but, I dont know which would be easier to work on, compiling from source or working on a direct port.
Any opinions on this? Any tips would be great.
EDIT: Nevermind. Someone is already working on a port over in the dev section and its bootable already.
Don't have anything to say but if you port liquid metal from acer to our G2 i will love you forever, even if it sounds gay.
Fly like a G2
Thanks. Hopefully I can get the ball rolling soon.

Hi, all. I picked up a new GSII from USCC a few days ago and I wondered what exactly has to be done to port CWM and/or roms from the E4GT to our phone. I'm hoping that the process will be fairly simple since our GSII is identical to the E4GT, excluding the WiMax radio.
Bear in mind that I'm running Ubuntu 11.10 before you give me Windows answers. But any and all help is appreciated. Your positivity could be the help I need to become a real dev.
Until you guys get a kernel source drop (Sammy's too busy violating the GPL... again...), it'll be difficult to know what is and is not actually different.
You may get lucky and it'll primarily be a kernel swap and maybe a RIL swap - but not guaranteed.
Source has dropped on Samsung site https://opensource.samsung.com/reception/receptionSub.do?method=list&menu_item=mobile&classification1=mobile_phone under SCH-R760U. Anyone give us some help on this, I'm also willing to give some porting a go, just need a little kick in the right direction.
I badly want to help get CM9 working, or at least learn from trying, on the T-Mobile variant of the GS3. I'm a pretty decent hacker, but I know I don't have enough / any experience with the Android OS / Kernel development to work on the GSM/LTE portions of the ROM. However, I feel that if someone could help me and anyone else interested to get the toolchain setup and source properly downloaded, we could help with the easier portions of the ROM and learn a little about the complex portions of the ROM just by watching what the more experienced devs are doing.
Right now, it seems like ...maybe.. a few people are working on their own rather than a collaborative effort (except the Sprint variant that has Team Epic working on a ROM). I don't want to slow progress by taking up a bunch of valuable dev time, but if one person could just help get some of the less experienced people off the ground, we could probably accelerate this effort...
In the meantime, would you guys mind posting some links to the best resources you have found for getting started building CM or even building Android in general? It doesn't really matter if it's a guide for a different device. I have searched but there is so much information missing in sources I have found.
Thank You,
KevlarTheGreat

I would love to get involved. I have a good amount of Linux and C experience (7+ years), but need a good place to start with Android ROM development (specifically for the GS3).

Team Epic is sorting it out, just be patient:good:

From what I understand, they are sorting it out for Sprint but T-Mobile is much different because it's GSM. Here is their reply to me when I asked if there would be CWM install scripts that would support both T-Mobile and Sprint from the same ROM:

No, there will not be ROM's that work on all variants. CDMA and GSM are quite different.
The tools like CWM will work on all variants (if made properly) because they don't use the radios.

I'm a bit surprised at this answer because I'm coming from the HD2 where tytung has two different versions of the kernel in his amazing CM9 ROM. It chooses which one to install automatically based on which radio support you have PPP vs RMNET.
I think our development fora should be linked with the other 7105 variants, there is significant progress towards CM10 and other AOSP in the AT&T forum.
http://forum.xda-developers.com/showthread.php?t=2018411
But, since there are four (ours, international 7105, AT&T, and Sprint), the devs are scattered, when unity would breed much more success. Our accessories is already linked, how about a linked development (not just the unused developers only forum) or moving threads like this to the linked dev forum? Either way, maybe this will help bring attention to the progress that has been made.
As long as i get aosp before the verizon or sprint varients. Glad to know progress is being made.

This isn't and shouldn'tbe about first, besides once one 7105 variant has a working device tree, we all do.
I am trying to get an idea of what the differences are between the phones. From what I gather so far is there is the international 7105 and its variants which are the tmo att and sprints versions and they are all gsm? Then there is the 7100 international and its variant which would be Verizon and they are cdma? But I thought that sprint was cdma carrier so wouldn't the sprint be in with the 7100 version?
From what I understand the physical and specs are the same for all the phones and the hardware is the same except the radio difference between the two. so the software is the major difference. I know on my last phone the sgs2 the att and tmo versions were almost identical twins the two were able to use roms interchangeably without porting except for minor kernel differences. In the end the only problem was the rotation was messed up. and it was fixed by using a the kernel that was native to the device. Like if you used a att rom on a tmo phone you had to use a tmo kernel with it. and also finally someone came up with a flashable .zip fix for it. The .zip fixed the rotation and also the build.prop so that the right device was in the build.prop. So that is what I foresee here in this situation. It will take time but it will happen. I know that we got some real good devs on the tmo side I haven't checked out the other variants yet but I am sure they got some real good devs too. A phone like this was bound to attract top quality people ( and schmucks like me too) I would definitely like to see a dev only subforum for all the devices or even a forum it doesn't have to be a sub forum because then the info will be fragmented because which forum do you put it in tmo, att, sprint, international. I say make a 7105 variant dev only forum for them to talk and work out some kick ass stuff. Like AOSP and cm and of course the ultimate AOKP. And whatever else they come up with.
7105 = international LTE
Variants include:
AT&T
T-mobile
Sprint
Verizon
7100 = international GSM
7102 = Chinese GSM/CDMA dual SIM
Differences include radio hardware/software.

Coming from HTC since the beginning of my smartphone career... I'd don't know jack about Samsung, Odin, and some other differences but isn't there a way to compile roms without the radio lol? Thta would fix alot. I'm sure there might be various issues between carriers but it should work. I get cmda and dual sim models would be different but at&t model should be able to share. As someone meantioned before, once at&t subforum has their branch... we will too. It just seems that mods separated the forums to cut down on confusion for the end user but it hurts development collaboration between development and hurts the end users who read directions and don't flash stuff blindly. I'm just not used to seeing all this talent wasted by being segregated like this. Obviously there is a reason I'm not seeing... whether due to total incompatibility or something else. It couldn't be that simple, could it?! In the meantime, I'm gonna continue to read up on Samsung development and see if there is anything I can do to contribute... no matter how small or insignificant

there is a way to compile without radios, most of the ROMs do not have radios, or they are optional. Problem is since the radio hardware is different, the kernel needs to be recomplied for the 7105/variants. I will say if they get it on 7105 then AT&T, T-mobile, and Sprint should be easy to get working (sprint would require blobs, T-Mo and AT&T should work out of the box. Verizon would work only if they 1) crack the bootloader or 2) make a special k-sec version of the rom. There is a new dev section that crosses all boards so that should help the devs some. Basicaly if we get 7105 AOSP we get TMO/AT&T/Sprint and possibly Verizon.
I saw on g+ that they got a bootoble version of cm 10 on the note 2 I do not know which model and it was not a dd but it boots. That is a promising sign. We will have it soon. I cant wait. For now I am sticking with stock until a working aokp comes out. That is what I did with my sgs2 when we got ics. I didnt even bother rooting it till aokp came out.
Cmenard said hes got aokp on our note but he s having ril problems...http://forum.xda-developers.com/sho...//en.wikipedia.org/wiki/Radio_Interface_Layer
Madmack in our forums has a fully working cm10 he says. He's working on getting up on github and then post a flashable version for us to test. Only a matter of time now.

i no longer need TouchWiz if GMD SPen Gestures is working on AOSP/AOKP
that's all I really care about, S-Memo I hardly use anymore.

Yes you can. Flash the cm10 floating around but be sure to flash the T-Mobile modem. I won't brick if you forget to but the reception/ signal will be much better. I'm using it as my daily driver. Its fast and amazing.

To my understanding, yes, you can. I myself am on NOTEorious Prime rom which is based on the N7105 firmware but was made for ATT, all needed to do is flash the Tmo radio to get data and since I like to overclock my devices I also flashed the Note2Core kernel which will work with N7100 and N7105 roms; and on top of that I flashed an AOSP theme made by foreverloco since I can't stand Touchwiz. Overall, the UI looks clean just like AOSP (but of course, it ain't the same:crying but you can also see some elements of Touchwiz here and there...
I mean, this is just for now until a more stable port of cm10 shows up for our Note2, like you, I also like to have a clean rom and not layer upon layer upon layer.

Audio seems to work fine. You have to make 2 phone calls upon boot in order for calls to work correctly And in the beginning of a call it sounds really low so you have to toggle the volume during a call and the. It will be regular and loud again. Otherwise seems to run great. I didn't flash any modems or extra kernels besides updated one that was in the thread.
Has anyone tried to port the N920T to the N900T? If this is done would the wifi-calling and NFC be broken to even though it's a TMobile rom?
Can I bake this myself? I know there are instructions, but I find them a bit confusing when they start talking about using a ASOP base and the such. Is there a REALLY good tutorial on this?
There is not really going to be an easy tutorial for porting the N920T ROM to the N900T and have everything working. Wi-Fi calling is one thing that everyone's had trouble with.
If you use any AOSP bases, then it won't be a Note port at all. You'd loose the S Pen features entirely unless you add stuff like S Pen Helper. AOSP and TouchWiz are two completely different animals.

You see, now that was GREAT ADVICE! Thank you so VERY Much! I found a a detailed tutorial here : , but some of the files that require changing or replacing are obsolete now.
It seems I should simply be able to Replace some files, Delete some files and modify the buildprop...and be good to go, but apparently it's not that simple.
Listen..I KNOW you are a busy man, but if you could just review the link, give me your VALUED opinion, I'll saddle up and "Get'er Done!"
Maybe it'll be easier to take an existing N5 Port and ...maybe Throw the Key software into the N920T port ?
Somehow I just feel like if it's MADE for Tmobile there's a better chance of NFC and Wifi-calling .

Yeah man no prob. I'll check out the tut they have written up. I personally haven't ported an entire TW ROM, but I know it's not all rainbows and unicorns trying to do it. Haha
I've ported apps and cooked up some AOSP ROM's but like I said, that's a whole different animal than TW. There is a lot of difference in the frameworks, SystemzUI, and a crap ton of different lib files.
On the part about it being made for T-Mobile, I'm not aware of an actual T-Mobile N920T for the N900T right now.
You could try starting with our Team DomPop ROM and add stuff to try getting the Wi-Fi Calling up and going. I can try and help you out some when I get time. Right now we're on the s7 Edge port.
Go to the T-Mobile Note 3 development section and click on our ROM. You can get the Note 5 port from the OP.

I've got the DomPop, and it is a GREAT port, but the international doesn't have wifi-calling, and the NFC doesn't work.

I've been doing some research on how to get Wi-Fi calling working and I can find anything. No wonder there isn't a ROM port with it working yet Haha. I will keep searching and if I come across something or figure it out myself I will definitely let you know. That would be a great thing to figure out. I would be able to add it to our ROM as well.
I really believe the reason it doesn't work is because EVERYONE is using the International for porting. No one is porting the N9XXT. I'm going to start SMALL and simple. I'll find a way to port the N910T...and work my way up.
