Hey there guys
I'm a dev from the i777 forum -- the AT&T Version of the i9100. My rom, ShishirROM, is based off of XWLPG Odexed -- one of the few i777 ROMs to be odexed. It revolves around having great battery life and stability, as well as being nicely polished and revolving around JKay's brilliant mod.
The page can be found here: http://forum.xda-developers.com/showthread.php?t=1505433
Okay, so I need YOUR help to port this ROM over the i9100. It should be very straight-forward, but I'll need a few beta-testers to make sure everything works as advertised. And being a i777 user, I need to know a couple of things to make sure the ROM is perfect out-of-the-box:
What are the most stable/fastest i9100 modems and kernels?
That's it for now, and I'll need some willing beta testers to PM me with:
Experience modding/testing
Ability to use adb / analyze logcats
Has plenty of backups of existing ROMs incase something goes wrong
Has plenty of time to beta-test
I can only take around 3 or 4 of the most qualified since I don't intend to have to give instructions with each package (e.g., adb push file to directory then chmod, etc.). I think this is the first time someone has tried to port an i777 ROM to the i9100, but I know it's possible and I could make the necessary changes and upload it right now, but I'll need to make sure it works first.
Thanks

if it would be that easy, everybody would do it
what do you mean by "good with computers"? do you know how to write code (C/C++)? are you yet experienced with running linux? have you ever compiled a kernel before? do you want to make a source-(AOSP)-rom (then you can get the source here: http://source.android.com/ and here: http://opensource.samsung.com/) or do you want to just theme and customize a stock firmware?
i think there are already some tutorials around which will help you in the beginning. just google for them!
i haven't done custom rom development myself but i would really like to get some (clean) aosp goodness on this phone. i am experienced with linux (use it since 6 years as primary os) and i can code c/c++/asm. so if you are in fact serious and able to go all the way. i would appreciate to help!

I'm pretty able to develop with Eclipse, so android sdk. Linux quite good, i prefer to use windows, but i know linux is necessary. First of all i'd like to know how to customize GALAXY fw and then i'll study how to compile a kernel, no one during my life helps me, and it's difficult for me because i'm not good with english and all tutorials are in english!
I'll try to work on it! Thank you
Can someone explain me how to cook a Galaxy S Froyo ROM with AOSP as the base and samsung drivers?
Could someone please explain to me how to flash the Korean firmware onto the European phone? Really need the native "record call" feature
I saw some instructions posted here
http://forum.androidcentral.com/hacking/40130-100-stock-captivate-rom-aosp-source.html
It's not difficult if you're comfortable with linux, shell scripts, custom kernels, and cross compiling.
Basically that's pretty much all it needs, Android systems are very similiar to a running linux system.
Boot off a bootloader (usually closed sourced) into kernel and initrd, then init loads the drivers, system and configs, after which is pretty much to your taste and likings.
Source code of android, samsung kernel source, are available online, google is your friend.
I've already got the groundwork in my other applications for requesting root, making su calls, etc. If kernel dev's are willing to post their kernels in an exact format, I.E:
kernelname-nand/sd/ram-version-date.zip:
zImage
initrd.gz (optional)
modules/*.ko
.. or even just PM when new releases come out for me to do it myself, then I could pretty easily put an application in market that will backup the existing kernel and modules to SD, then auto-install kernels based on a scan of existing files.
While it's not a lot of time, I don't want to go down that road unless there is interest, so let me know.
*mods*
If this belongs in Q&A, feel free to move, I just thought it made since in the dev section since it will involve kernel devs.
Thanks,
B.
*edit*
Since I know this will be the first question: Yes, it will be free.
Hey guys I created this to show progress on porting AOKP from the S3 and get some collaboration from devs. If any devs want to help please chime in. I can send my zip file of my attempted port. So far though I am going to need a ported kernel, the one in my zip is just our stock N7100 kernel. I don't have the note ii so I have no way to test it, and I only feel comfortable having devs test because I am not at the point of releasing anything, and have not yet asked permission to use other dev's work. Basically once this is booting and stable I am going to get permission and I will post it up in the Dev section.
HI all , i lunched this thread after weeks of googling and usless search for a new stock or custom rom to update my phone (samsung sgh-i857 doubletime) it's a dual screen phone with querty built-in keyboard it's from at&t and it is stuck on android 2.2.2, i'm very sad that they and after years from lunching it didn't back it up with a single soft update -_- ... and i know that there are users who bought this phone like me and seek help.. i know that it's not this easy but if you are a devloper help us by creating a custom rom for it ....if you are a user of this phone please support this thread by commenting so we can get an update for it :good: ps: i attached informations for it's cpu
Hello good sir, I like you am a noobish Doubletime user who is struggling to update it to Gingerbread. So far I have been somewhat able to use the Cyanogenmod source code and I have built a CWM Recovery for the device but that seems to have hard bricked it... I ordered a new one off ebay for $15 and I'm ready to start cooking. You have my support!
Just an update.
I have a plan I have on how to get this runnin.
1. Port CWM to the DoubleTime through Cyanogemod 6.
2. Get a working version of Cyanogenmod 6 working on the DoubleTime to hopefully free up some space.
3. Find if Gingerbread can run on Froyos kernel.
From there I'll either be building a GingerBread compatable kernel or Cyanogenmod 7 depending on compatability. Any advice or help would be very appreciated.
Being new to ROM building I'm a little lost and hesitant on flashing things but here's what I know so far.
The DoubleTime uses a Qualcomm MSM7230 same as the HTC Vision. I forked it's Github respiratory and I'll be using it as a base as recommended by the Cyanogenmod porting guide.
The partitions sizes (as a accurately as I can estimate them) are:
/cache=21.05MB
/data=176.65MB
/system=194.38MB
I may need to know the recovery partition size but I'm not sure how to find that out.
I have the recovery.img and the boot.img as well as the zImage. So as soon as the repo sync is done I'll be on my way.
I'm back again today with somewhat mixed news, I can find most of the partitions and their names (I've learned a lot today) but I can not seem to find the boot, recovery or ramdisk partitions. I'm already boggled by the what seems to be unconventional naming setup for partitions. Put all of my "notes" in a text docement in the attachments section. Any help with this is very appertiated. I can type and post anything into the ADB shell you need me too.
I'm beginning to feel like I'm talking to myself, I probably am...
Upon reading forum rules and such it has come to my attension that this is the wrong forum for this kind of thread, So I have made a new thread in the Miscellaneous Android Developement Forum that will hopefully be more useful at getting more proffesional and opinionated help.

Hey guys
I'm currently working on my first custom ROM mainly because there are currently no ROM for the dreaded G900H (aka Exynos) version. For this, I already downloaded a stock ROM and created my environment using Android Kitchen. So here are my questions:
1. I was able to follow and execute all the instructions to extract the custom ROM, install root and busybox. But first... is Android Kitchen even compatible with Galaxy S5?
2. Is it important to keep the CSC info on the new ROM? How can I backup current CSC info from my stock (carrier provided) S5?
3. How probable is to brick the phone if I flash a very alpha ROM as the one I'm supposedly cooking? I already have a nandroid and EFS backup
Thanks in advance for your answer and patience.

i need custom rom too for my sm-g900h
could anyone post full guide and video showing us how make our custom rom?
really appreciate

Me too, I am on the same wait. Please and thanks. :good:

Sent from my SM-G900H using XDA Premium 4 mobile app

Is there still no hope for the s900H ((((
any rom?
I cant believe no custom rom for my s900h phone. Million of users all over the world, including latin america, asia. If Iknew how to built one I would, but I have no Idea. Developers where are you?

Funny, implying that this is an statistics game. It is not and it's ridiculous to blame developers for the lack of support.
Pretty much everyone that actually develops got the Snapdragon variant, if I had a choice I'd gotten that just by the amount of code and AOSP possibility.
Exynos was only supported by a couple of devs, it's all Samsung's fault - not devs. None of them currently has an S5.
Use xposed, greenify, titanium backup and there are few reasons you'll need a custom rom.
Xposed opened a new world of possibilities to modding.
Edit: Exactly that demanding attitude is what puts devs off. Other regions are usually more polite and grateful and that's something devs have noted in the past....

Sorry if I didnt make myself clear. English is not my first language. When I mentioned the millions of user was only to imply that more users, the more chance to have a genius among them. I didnt mean to have a demanding attitude. I was trying to say "Iknow you are out there, I know you are developing something for all of us. We are here waiting for your effort.
@CiDev:
You want to share your ROM for "H" here?
i dont think that will we have any custom rom for our model
but according with this http://forum.xda-developers.com/showpost.php?p=52168627&postcount=168 @Shohat told me that he will release custom rom until end of may,,but nothing..
maybe he is busy

I wouldn't bet *anything* on it being released, it looks to me like an abandoned project...
The whole 'I can't work on this because I don't have money' turned me off instantly from that ROM.
On topic: I have been working on a custom kernel for our device, mainly trying to improve battery life. I'm still testing, if it's worth it, I can release it.
It's based on the contributions of others, so it wouldn't be fair for me to keep it private, I just don't want to release something that will break stuff.

1 - yes.
2 - make an nandroid before
3 - if you have a brick, restore from your nandroid and ready again
