Anyone plz help.i m trying to create a jelly bean custom rom.plz tell me how to create jelly bean custom rom

i can tell yur not a developer, u can build from source provided by google or CyanogenMod etc... They all have guides how to build depending on ur device. the process requires a computer on a Linux system such as Ubuntu or others. The requirements are posted around google.

Gfive luminous e660 running on mt6575 gingerbread.i successfuly installed cwm recovery 5.5 on it.

well it may be possible, building from source that is. but i myself cant help, dont have a computer in hand, do u know if they have released kernel source? if so that can help with custom kernels, maybe leading to ics, even jellybean if its possible. But kernel source is highly preferred, since it can help the building process. also since this phone isnt a knows device here were i am at i cant help or troubleshoot.

You upgrade a kernel version, by upgrading the kernel updates for that version.

It is pretty self explanatory.if you want a 3.0+ kernel, then merge a 3.0+ kernel into your source. Most aosp kernel track from the linux kernel. I am not going to get into the step by steps about it, that you can google.

One of 4 things, Wait, merge from the linux kernel, merge from a 3.0+ device with similar hardware, or cry about it.

No, pending your source, and the other source, there are way to many different changes that could take place. I would use a tool like beyond compare and diff the folders to see what files are different, then based on your experience, start making changes, compile test, rinse and repeat.

Before you start working on it, nandroid backup your system. Its just the kernel, so you can always revert via recovery. Though you should already know that.

One wrong step in kernel can hard brick my phone right? Seniors in my forum have taught me not to mess with a kernel unknowingly cuz it has high chances of hard bricking the phone.

That is crap the kernel gets initialized during boot, unless your kernel is flashing a recovery as well, or your using a device without a dedicated recovery?
What do you mean by a dedicated recovery? I am using a samsung phone and we have a recovery mode and a download mode. We have both a permanent cwm and a zip fiw cwm(temporary).
Sent from my GT-S5360 using XDA
the dedicated recovery is a partition on is own, so lets say your mtd/emmc is structured like this
boot
recovery (this should be the dedicated recovery)
system
data
therefore you will be able to delete/flash/reflash the boot without affecting the tablet/system/other partitions
There are some devices that have a different recovery structure (tablets based on the rockchip soc)
Thanks for the help you both! I will learn more about partitions in my phone and come back on this thread.
Sent from my GT-S5360 using XDA
I guess most Samsung phones doesn't come as a recovery partition, it comes as an extra ramdisk as mentioned here.
Anyways I've flashed boot.img which I've compiled, and the first boot was a bootloop, of course. And after doing some changes, compiled again and flashed, and it was a success. So I don't think Kernels can hard-brick the device (IMO though).
For samsung...as long as you have download mode your in the clear...with download mode you can use Odin or heimdall to flash a working kernel or even stock software to return to stock.
Samsungs do not have a partition for recovery...its its own ramdisk..."recovery-ramdisk.img" so you can lose both recovery and boot with a kernel but with download mode and heimdall all you have to get is a working kernel with a working recovery, open terminal and type "heimdall flash --kernel kernelnamehere.includinganyfileextention" so "heimdall flash --kernel boot.img"
Sent from my SGH-I997 using Tapatalk 2
You guys rightly said! We have a ramdisk included with a zImage in a boot.img. I have also seen cases where the recovery mode doesnt come but the download mode is still intact.
A guy from our forum once flashed a s2 kernel on my Y and he hard bricked it. No modes were opening on his phone but according to the theory given by you guys, atleast the download mode should have been working! Care to explain me why that happened? I think the same thing will happen with me when I use sources of other phone for my kernel.

So what I read from this thread, if you don't have a recovery dedicated for your device you would hard brick it???
Coz I tried n tested some kernels
They didn't work out -but it was a soft brick
Not a hard brick
I had not made those
Now I'm willing to try once I get some hold on building kernels
And I have a Sony Xperia Neo V
It doesn't have stock recovery like Samsung so if I make or atleast try to make kernels on my own, would I risk my phone getting hard bricked???
Or just soft brick?
Ty for your time!

Best method to build a rom ???

Can someone provide me the perfect tutorial to build a rom ? From the start using a base rom plz tell the environment required and how can compile ?? im asking this coz i tried using cygwin to create a touchwizz themed cm9 rom ended with no result either the phone wont boot or i get status 6 error !!! Plz anyone help
Sent from my GT-S5830 using xda premium
You know codes.
Using a base is "porting" a ROM not building one.
There are a bunch here on porting, but in the end its a lot of trial and error. Reading logcats, an working from there.
Since the ported ROM wasn't built for your device, there's no specific directions on how to do it and have it work for every device out there.

If theres not already a master ICS source for your phone(No device tree),then yes you have to use the custom ICS rom on your phone so it can copy the right proprietary files to the source you repoed,or it will not run,you will get bootloops or a soft brick.

Hey, do you have a noobs guide on making a device tree. I know how to compile cyanogenmod, but I have this low legacy device, the Samsung Dart, and it doesnt have a device tree. I want to make ics or jb for it, but have not a clue how to make a tree, all my other phones are htc and samsungs, they already have some.

[CM10.1 Tree]Galaxy Mega 5.8 GT-i9152 Device Tree

Hi there guys i have seen total 0 development for this phone here in xda, as a proud user of the Mega 5.8 i must kick start the development.
Well recently i have got my hands on the device and i am very pleased with how wonderfully it performs, anyway so here it goes.
I have started working on the CM10.1 device tree for GT-i9152. Well thanks to pawitp for his GT-19082 tree from which i have forked most of the blobs and started working on.
First target is to compile a bootable version of CM10.2 with Grand dependencies on which i and herna will work on to make a complete tree for GT=i9152.
So here is the initial commit. feel free to push any commits as you want.
https://github.com/RittikBhowmik/android_samsung_GT-i9152_crater
lets kick start the development. For now i will be using stock kernel sources with few changes to make it bootable,as we all know the first "wip" or "dev" is never stable, we will learn as it all gets started
Will be updating the kernel sources soon.
Credits/Working with me
pawitp
herna
Somcom3x
will need few testers to test out the first builds,feel free to PM.
Updated Most of the blobs. Dedicated tree for Crater
I could help you a bit guys
I just need stock boot.img, kernel source and build.prop
Im 9152 user and feel so thirsty cause no mod for this device running well except root only. Come on man, keep up the work
Garak kernel source is on samsung open source and build.prop will provide you. My device tree now needs the kernel source and the vendor tabs. After that am good to go.

Trying miuiv5 and silesh building cm11. PM me for more info. Testers needed.
Good night Rittik,
What is needed to test the rom? For a long time I was a Motorola Atrix User and have always enjoyed using the custom roms of Cyanogemmod, and currently miss Cyanogemmod for our Mega 5.8.
At the moment I'm a Mega 5.8 and did the unlock bootload, and installed the Cokelat the Jusho rom for testing, and it has worked well, do not know what he did developing this version, but I would use a rom patterns of Cyanogemmod.
Rittik, thank you for the initiative to develop a custom rom, I've been researching and found nothing enquando for our Mega.
Rittik not know at what stage of development your rom this, but if you need to test it, I'll be available.
Tks.
Ricardo.
