Custom ROM for SG3 - Galaxy S III Q&A, Help & Troubleshooting

Hi,
What's the best ICS Custom Rom and kernel form SG3?
Thanks,
Raven

I hate questions like this. The only answer you will get is - "Find out for yourself".
You can look at the popularity of a developer or the ROM they have posted and use that as a judgement whether you want to flash it or not.

At the moment I am using Omega 4.2 ROM and SiyahKernel 1.0 overclocked at 1.6GHz. Give these a shot, they are pretty good

Is there a way to preserve all my settings/apps so that after I flash a ROM everything will be still current?
I understand ROM's need to be flashed(to prevent errors), but surely there's a way of getting all the settings back without having to set up the phone from scratch?

Just wipe cache/ dalvik before wiping and leave data. Nothing will be changed but the system and kernel.

thread closed - try them and see what's best for you

BLN kernel New to Fascinate

New to modding the fascinate, its not mine but they want the BLN so my question is, is there a kernel that can go on stock 2.3.5? Rooting is not a big deal just wondering if theres a way to keep the stock rom with a different kernel
forum.xda-developers.com/showthread.php?t=1364912
This kernel should work if you're on stock EH03 2.3.5. Clear cache and dalvik, flash in CWM. If you have any questions regarding flashing there's a few stickies in these forums that can help you. I recommend SuperClean as a rom as well, or GeeWiz. They are much more efficient than stock yet at least as stable. Good luck!
Edit: Darn ICS spell checker...
So flashing that kernel i dont have to wipe data do i?
And since its on 2.3.5 do i have to do anything special like go back to an older version or anything?

No and no, but you have to wipe your cache and dalvik cache or else you might boot loop.
so what would be the easiest way to root this bad boy? any app that can just be loaded onto the phone such as z4 or do i have to use adb?

[Q] Can this phone info use OMEGA,Wanam or other ROM?

Thank you for helping me...
i9300 is the international phone, so yes.
The installled ROM, kernel and baseband are irrelevant if you want to change ROM.

Any recommendation stable and fast ROM for me?
Another question if I want to flash to OMEGA 7.0 ROM can I just simply flash from my phone setup now : IMM76D.I9300XXALF6? Because ROM OMEGA 7.0 they use Based on XXALF5...Should I downgrade to XXALF5 then flash rom to OMEGA 7.0 or I can straight away flash base on my current setup?
Still learning and learning and learning and learning....Please don't dont giveup teaching me...hehehe...
Read and follow directions of the Rom you choose. Make sure you do backup first then,if you don't like it you can go back or flash another. Runs are pretty subjective and cater for a variety of tastes so hard to recommend one. Most want super fast with best battery life but there is a trade off

You should always factory-reset when changing Rom's.
It thus doesn't matter what ROM and version you come from and go to.

I'm still running ALE8 with Siyahkernel. Works great after a few customizations and tweaks applied as found here in the forum. Most ROM's have trade-off's (e.g. they want to slim it down and remove libraries or features I consider worth it)
You won't see a real performance difference between Samsung-based ROM's.
Actually you _WILL_ see a difference at the beginning since your phone is then again factory-new without lots and lots of apps and background services.

How to install ROMS on UCLE5 Stock ICS Root w/ Siyah v4.3.3 w/o mic swap

After reading over lots and lots of threads, I finally got up the courage to root my phone.
I followed these instructions: http://forum.xda-developers.com/showthread.php?t=1746181
I flashed the "Kernel + Modem + Cache + Rooted UCLE5 System Package" using Odin, downloaded Mobile Odin, and then flashed the safe Siyah 4.3.3 kernel w/o mic swap to avoid bricking due to the eMMc bug. Everything seems to be working fine. I have Superuser, Mobile Odin, and CWM Recovery.
My question is what are my ROM choices and how do I go about installing them?
I'f I'm reading the instructions correctly in the thread with the rooting instructions, I only have the three options for kernels in that thread and I MUST use a w/o mic swap version.
On the Siyah thread: http://forum.xda-developers.com/showthread.php?t=1592228, the only ROMs listed that work with w/o mic swap Siyah are Criskelo and UCLD3. Are these my only choices for ROM?
Are these the proper files for Criskelo?
Criskelo: http://forum.xda-developers.com/showthread.php?t=1500891&highlight=criskelo
I can't seem to find the files for UCLD3.
To be clear, I was coming from a stock i777 with stock ICS and UCLE5. I'm now running 4.0.3, I777UCLE5, 3.1.0-rc8-Siyah-v4.3.3-nomswap ([email protected]).
Thanks for any help. I've searched and read a ton, but I just can't make sense of it all.
You can use any rom you want. It will come with its own kernel and overwrite the one you have

So this from the the first thread isn't true?
"You must use an ICS kernel, and it must work with Samsung firmware, and be the no-mic-swap version. If you install a Gingerbread kernel the phone will not boot."
Sorry, it's all a bit confusing to me.

Then don't go and mess with your phone if you don't understand what you're doing. The information is not that complicated.

Just do as Pirate says and you will be fine. Dont worry about the kernel because the rom you want will have the appropriate kernel packaged in

it means that if you use an ALTERNATE kernel, which a lot of people like to do, then you must abide by those guidelines. all roms come packaged with a 'recommended' kernel....just flash one and you will see.

Ok, so for this ROM: http://forum.xda-developers.com/showthread.php?t=2005266
How do I do an EFS backup? I have searched this, but haven't found anything specific to this phone. Just want to make sure I am doing it correctly.
The next step is to do a FULL BACKUP. I did a backup in CWM Recovery. Does that work?
When I move the ROM to my phone, do I take the whole zip file? Is there any particular file(zImage?) I point to when flashing through CWM or is it the whole zip file?
Thanks again for all the help.
I successfully flashed SHOStock2.
Thanks for the help guys.

Yepp that is a Nandroid backup

Nope just keep the whole zip and select it in CWM

Good choice for a first ROM. When you get bored with that Shostock3 is really nice but wait until 1.5 comes out. It has some fixes that will polish it up nicely.

Would going to SHOStock3 require a wipe? I understand that upgrading to new versions of an existing ROM usually does not, but since this is a different ROM it seems like it would require the full wipe.
What is the easiest way to retain as many of my settings, etc... as possible when doing full wipes? I have Titanium Backup already. Is there another program that will help me retain more?

Yes on the full wipe before flashing the new ROM.
What else are u trying to retain besides apps and their data? If that's all TiBu is fine

It would be nice if I didn't have setup e-mail everytime, but if I can keep my apps and their data with TiBu, that should be fine.

Once you get accustomed to it, flashing with a full wipe isn't too bad. Make a nandroid backup in case you decide to go back. And I would recommend you buy the full version of titanium back up to get the batch features, and support the developer. It is probably the most important app for those that flash regularly.
I can fully wipe and flash and have everything back up and running the exact same way it was in like 10 minutes. But I like the chance to start fresh

[Q] ROOT+Kernel Q

Hey guys,
I wanted to ask if its possible to get a custom Kernel and rooting my international S3 without losing all my apps?
I just dont wanna use Titanium since it would take forever since i've got alot of apps etc.
I've rooted and put a custom rom on another phone a few years ago and i still remember this would delete all your content as you install a new rom,
and i would like to ask if i can avoid that?
Best regards,
DrLuigi

rooting and installing a kernel does not wipe data and you also do not have to wipe it
even flashing a rom does not wipe data, except you choose to wipe it (which is recommend if you change android versions)
CF auto root, guide on how to use it in general forum, stickies. It won't wipe your phone.
Please search before starting new threads.
Do you guys perhaps know a good kernel that can go along with the stock rom that should be safe to not wipe my whole phone?
I know you shouldnt ask for the best rom and such, But this is a specific question.
Thanks for the help.

there are so many: devil, boeffla, googy_max are just some examples I know which work with the stock rom and they are all great (the other ones i have maybe forgotten as well), just try them out and choose the one that suits you best.
and don't be scared: they won't wipe your data

Samsung S3 got very slow and laggy

hi my best friend has a samsung s3 and it got really slow and laggy over time. It takes several seconds to get back to the home screen.
I cleaned the cache of her phone with an app, but it's still far away from fluent. I also suggested her to use nova launcher, but she didn't like it, because she can't use the samsung weather widget.
Is there any easy solution how I can help my friend?
factory reset and too complicated things are not an option
thanks xoxo
Factory reset is first and easiest option, not the last.

yeah I also thought about that or a slim reliable costum rom. But she doesn't want to backup all and install everything all over. Too much effort for her. :laugh:

Also, root and some debloating and installing a new kernel can help
