Roms have to be specific to our device to work. There are plenty of roms running right now on our phone. More are, I'm sure, being ported over. You just need to give it a while. I'm sure we'll have plenty more roms coming this way, just need to be patient.

Hey all,
Been running ROMs on my Hero for a while now but I'd like to give the stock 2.1 a try and possibly stick with it until CM6 is stable. I know I can install the RUU but I don't really want to lose my recovery partition, I had to use the gold card method which was a pain in the ass.
I don't need root, I'd actually prefer to get a non-rooted completely default factory ROM if possible. How would I go about doing that or do I need to install the RUU and re-root it later if I want to? I've seen some "stock" ROMs floating around on the dev forum but all have been rooted and most seem to be running custom kernels too.
Any info or a link would be appreciated if I can keep my recovery part. Cheers
Villain Team has posted the GSM roms. There's pure stock and rooted stock.

ICS roms are beta at best, I wouldn't advise flashing one.
There is CM9 which is AOSP and there is Samsung leaks, all need ICS bootloaders, search and read before you even consider flashing any of the ICS roms.
how to get ics bootloader?? will it be automatically there if i flash a ics leaked rom??

all ics rom flashing instructions are just flash by cwm & a full wipe???

Depends on the rom, stock ones will come with ICS bootloaders, you *may* need them first for CM9. Also if you want to go back to gingerbread from ICS you will most than likely need to flash back to the old bootloaders from this thread.
Hi I would like to ask whether rooting the phone is the same as unlocking bootloader. Thanks!
No, it's not.
Rooting allows you to view and edit system files.
Unlocking the bootloader allows you to install custom (non-official) kernels.
So rooting my phone and unlocking the bootloader is 2 different issue?
Or does rooting my phone actually unlocks my bootloader as well?
Rooting does not unlock bootloader.
Unlocking bootloader can help root your phone (installing a pre-rooted kernel, for example).
Is it then possible to install a custom firmware without unlocking the bootloader or will there be problems if I install a custom firmware without unlocking the bootloader.
These two custom ROMs are the only ones that can be installed without unlocking the bootloader.

OK THANKS! SHALL GO CHECK IT OUT And can I ask, does the phone by itself already have a kernel? If it has, what is the use of installing another one?
Stock ROMs have their stock kernels.
Custom kernels can add some features, such as (for example) the chance to overclock the CPU. Almost every custom ROM needs a custom kernel to work properly.

Wrong. Custom ROMs do not need custom kernel to *function or work properly*.
The custom ROMs are installed at the Read Only Memory of your phone.
For that, you need to use an installer which has to be somewhere outside the Read Only Memory. Only such location on your phone is the kernel. So a custom kernel does nothing but adds an installer outside the Read Only Memory (that is the CWM Recovery).
Now to intall a kernel, you need an installer outside of your Read Only Memory as well as the kernel. That's the PC, and the installer is Flashtool. So, flashtool is used to install custom kernels on your phone.
Note: The two ROMs which can be installed on locked bootloaders are exceptions to this rule.
Thanks,
Rick

If it were like you said, any custom kernel could work with any custom ROM, as long as it has a Recovery to flash the ROM. There are different custom kernels because there are different ROMs, and each custom ROM works only with one or more custom kernels, but not with everyone. If you were right, one single kernel with recovery would be usable for every custom ROM.

Yea. It would be. Infact it is.
However, ROMs like CM9, which are NOT based on the stock ROM will not be able to work on the stock kernel. It will require a kernel which has been designed specifically for CM9. On the other hand, we had seen MiniCMSandwich, which looks like CM, but is based on stock ROM. This will work on any kernel that has a custom recovery. MESA, Rage, X, Stock Exteneded and so on...
So, to put it in other words, suppose you plan to flash an HTC Phone ROM as it came in the HTC device on your Xperia Device. You plan to just change the drivers. You will need a kernel which is designed for the HTC ROM.
But, if you, on the other hand, start with the Xperia ROM and change the aspects of this ROM into the HTC ROM's, you can make the ROM work on any of MESA, X, Rage or extended.

Stock extended, yeah. Try to run MiniCMSandwich on Gingerbread stock extended kernel. Will it work? Of course not. All the kernels you named are based on stock ICS kernel, so it's simple to run ICS based ROMs on them. This doesn't mean that every kernel with recovery can make them work

Stock GB is to Stock ICS is same as Stock Xperia ICS is to Stock HTC ICS. They are different ROMs. Completely.
The ROMs have instructions according to which it behaves with the kernel. These instructions are all same for kernels that are based on stock ICS. So if you want to try any ROM that is based on stock ICS and such kernel will do.
But CM, GB, HTC ROMs and so on, are completely different.
Say you want to port an HTC ROM to Xperia ICS. You can do the following (I am taking example of the bootanimation file)
1. Simply change the bootanimation.zip file at /system/media of the stock ICS ROM.
So your ROM is based on the stock ROM itself. You just change the files, not the way the files are accessed. You do not even change the way the kernel is accessed. So any kernel based on stock ICS *with recovery* will do.
2. Change the whole Read Only Memory Partition.
This makes all the files replaced, the way HTC has made the ROM. This time you will need a kernel *again with recovery*, built to be accessed by the very specific ROM.
Thanks,
Rick

I'm currently on GB, do I need to install an ICS rom before I install a ported JB rom? Or can I go straight from GB (with doing a full wipe before hand of course)?

i have not asked him to flash bootloader
i said
ics bootloader is reqd for aokp roms 4.0.4 and jb 4.1.1
there are users who flash jb directly from gb roms and gb roms have gb bootloader so they went into semi brick and had to flash back to stock rom

Again, WTF are you talking about. That's not true you never need to flash bootloaders for ANY reason.

You are probably confusing the OP. DO NOT listen to this guy.
Thanks a lot for the answers guys. Just out of curiosity, why is neerajganga saying an ics boot loader is needed? That doesn't make sense to me because I've gone from GB to ICS without ever having to touch the boot loader.

I think you are confusing bootloaders for kernels. But by calling it a bootloader you will confuse the OP into possibly screwing up their phone. I don't know if you need an ics kernel for jb. I'm just trying to clear up the misnomer.

Being what I just went through with my phone... I assured I was flashing an ICS ROM with a proper kernel. Then move up into JB. I had flashed a wrong kernel and wound up having to back track and redo allot.
May seem like more work yet taking it step by step sometimes in the end is easier. Just a word of thought from a noob who twice thought he bricked his phone. Yet now works great on CM9 thinking of moving up into CM10 soon.
The new versions of siyah and dream kernel are both ics and jb friendly may be more but these are what I use

neerajganga, I think you're in the wrong forum. This is for the ATT SGSII model I777, your sig indicates you've got an I9100 (though that confuses me because even I9100 users never need to flash bootloaders except in softbrick recoveries, just like I777).
What is the most versatile stock rom that i will flash after rooting and putting a recovery? Or it depends on the custom rom to which stock rom it will require?

Not sure if i got your question right, but there is not so many options for z5c.
Most versatile stock based custom is Kryptonian. Other one is xpower, but its more about debloating than adding mods.
Both devs have said that new version should be just around corner.
Then is of course cyanogen based roms, but unfortunately at least in my opinion not for every day use.
