Guys, I know this has probably been asked 5 trillion times on here, but I am new and would like some information.
I had an iPhone until a couple months ago, but then I decided to get an Atrix. I sold that, and how I have a Galaxy S II. It has the stock rom, and it is the European i9100 version. The phone is NOT rooted.
Do I need to root the phone before installing Lightning ROM? Also should I back up my music and stuff? Will my stuff get deleted after installing the custom ROM?
Thanks a lot for the help. I know most people will tell me that this has already been answered, but I really wouldn't mind some extra help so I don't brick my new phone.
Edit: Oh right, I forgot to add, will Lightning ROM increase my battery life? The stock ROM drains battery so fast...
As far as i know, you do not need to root to flash this rom. Flashing this rom though will root your gs2. Im on lite'ning 6.1 and its giving me great battery life.
Theres a link to FAQ in the lite'ning rom thread.
Edit: i would do a back up just incase, but NO it does not wipe anything on your phone.

To install any ROM root isn't needed. But some ROM will give you root access.

Hi guys im a noob (yeah i watched the video)
Can you tell me the best rom for me?
I want a stable rom and kernel with at least gingerbread 2.3.4 pre-rooted kernel must be overclockable and undervoltable (btw i would be happy if you told me best undervolting settings at 1.6ghz) it shouldnt be a Battery eating rom and i want it to be highly customizable (not really neceasary) and it shouldnt be updated frequently (wont be necessary if it is stable and enough) thx already sorry for bad english and for being a noob this is my very first android phone.

Repetion of standard dumb question yet again.
Five times today already
About time we had a brain dead section.

noob + overclocking + undervolting = wary result.
Anyhow, If bleeding edge is not your thing, you could try Cognition 1.5.1 with Ragemod kernel (in Original Dev). This is quite stable for past MY USAGE and fits your bill.

I would recommend revolution rom in original android development.
Root your phone. You'll need a kernel with clock work mod installed.
Download the kitchen app. Open the app. Press menu download rom. Then install once download completes.
Once done i would recommend tge cf root kernel v4.2 downloadable from the app. It's quadrant scores are over 4000. I only loose 1% battery overnight and another guy using the rom and kernel went 6 days without charge.
This kernel you cannot undervolt or overclock buy clearly you won't need to.
Sent from my Galaxy S2
If you have time, try them and find what matches your requirement.
revolution rom with kitchen app is cool option you may try Darkytool too to uninstall or install apks.
im using batista 2.0 with speedmod kernal and it is sick !!!!! try it let me know what you think
You're only going to find the best ROM for you by trying them. Become familiar with Clockwork Mod Recovery and something like Titanium backup and flash 'till you find something you like.
I'm using Villianrom with the Nymphetamine kernal and I couldn't be happier.
Thanks guys im now using sensation with siyahkernel but i will definitely try Revolution with kitchen app

Batista70 Foxhound 2.1 ROM seems great. Also checkROM. I use Revolution ROM. Don't know, just try them all, it's fun!
Defiantly Resurrection Remix or RootBox for now any way
And kernel either Fluxii, CM9 Remix or Siyah
Thread closed
Bumped from last year? Best ROMs are subjective, test them and make your own decision.
I want to know good ICS (android 4) custom ROM for my galaxy s2. Please tell me if you use fantastic ROM.
Love ICS
I must say that I have really liked the move to ICS. I have found it nice and smooth, and the battery life is great for me.
Although I have been a big user of custom ROMs and kernels in the past, both with the SGS2 and the Tab, in the case of ICS I have not felt the need to move off stock. As per my signature, I currently run stock LPQ with the LPQ CF-root kernel and it is working well for me (other than a cifs problem with my network drive at present). I will move to the Australian (non-carrier) ICS when/if it arrives, and give it a try.
Jacko
PS: I have added the Apex Launcher which I also like very much.
Stop being lazy & try a bunch of ICS roms till you find one you like :-| No excuse for not doing so given how simple/quick it is to flash a rom in CWM & also to backup/restore.
I can recommend CM9 Works perfect
I recommend Koud AOSP 4
I'm on this from now and my internet is faster than its ever been.
For some reason this from doesn't come with a file manager I recommend astro or ES. I got astro.
Haven't had it long enough to comment on battery life.
It does NOT have root but it does have clockworkmod recovery so you can easily go back to your old rom if you made a nandroid backup. You can easily root the ROM with Odin with LP6 kernel from chainfire search chainfire lp6 on xda to download odin3 and LP6 kernel.
The thread has instructions to flash the kernel.
If you don't like using Odin or any similar programs or don't know how to or can't get to a PC right now
I recommend Pure ICS v7.1 or newer if its been updated.
This one is rooted.
Battery life is pretty good.
Its looks almost the same as koud aosp but they do have there differences. I think the other one is faster and more smooth UI. Although pure ICS is still a great ICS copy I used it for weeks before I found koud aosp.

I just bought a used galaxy s2 I love the phone already. I had the samsung infuse before, and I loved the cm7 nightly builds on that phone, but had to upgrade You all know how that is haha.... I used http://forum.xda-developers.com/showthread.php?t=1505172 to root and then had to unlock seeing as I am on rogers.... First thing I have to say is that every time I boot up I see the triangle with the ! in it so I might have done the wrong one? It said before i had the i9000m btw. And I installed CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4 as the kernel
Another thing I might as is that when I tried to open odin 1.85, it would say Odin.ini with a bunch of sqaures, i press ok and it closes.... So i just used 1.83.
Last thing is who do I go into cwm recovery, and I want to go on a cyanogen mod 7 or 9.... Should I try cm9? And how would I do that?
THANKS!
Hope everyone here is more helpful than on the infuse sometimes
the yellow triangle is always there when you boot it cause you rooted it.. but gladly, you can remove it with a usb jig (http://www.youtube.com/watch?v=udzMQ_dsci4) or without usb jig (http://www.youtube.com/watch?v=YOXNf_kH-iA)
I highly suggest skipping CM9 and giving Resurrection Remix a try. Also learn to live with the yellow triangle and forget the CF kernels. I use Siyah kernel and there are other alternatives just as good.
I've tried almost every rom and kernal for S2 and I truly believe RR and Siyah is the best performing combo of them all.

Thanks I will trythat now, but how do I do that? I sent you a message
If you don't have a usb jig to reset the flash counter and remove the triangle on boot up try chainfire's TriangleAway app either found on the play store(paid) or in his thread here on xda(free). Make sure you are running an ICS rom.

Sorry I meant how do I do the siyah and rr thing but thanks
I received your message. All the info you will need is right here on XDA already. When you rooted your phone you probably installed CWM recovery (press home, volume up and power buttons to boot into it). Assuming you have that you can just follow the steps in the RR thread to install. It already comes with Siyah Kernel so you can simply flash the latest version to keep it updated. I used odin to flash a modem firmware for Canadian networks but that's optional since the stock base band in rr worked fine.
Sent from my GT-I9100 using Tapatalk 2
So that means all I do is flash rr from cwm and clear that bs stuff and I'm good to go?
Sent from my GT-I9100M using xda premium
Its simple as that Just follow the extended steps in the faq of the rr thread and remember to make backups in cwm in case you make mistakes and need to try again.

if u need to do a factory reset/full wipe in the process of intalling the new rom
all apps and data will be deleted
so its convenient to make backup important things like your apps, sms, or call log
not compusory though
backup apps using Titanium backup,there are free and paid version

Stick with GB. CM9 AOSP AOKP and Samsung ICS roms will give you a headache, poor performance and poor battery life. My two cents.

Hi,
I have been away for a long time here. Been using checkromhd v6 since then. This is a GB rom.
I thought maybe its time to get me a new rom.
I come here and see al these new features : mali, vsync, aroma, dualboot .....
Isn't there a romguide or something? Because this all is getting very difficult.
On gingerbread I think it was easier.
There where lesser option which made it easier to choose. There where also fewer cooks for the SGS2 back then.
If anybody can help me a bit coming up to speed with al this new stuff, I would be very thankfull.

Hey.it's always be guide how to install Rom in these topics...
Send form Galaxy S2. Using XDA Premium
The stickies in the general section have guides to everything right from upgrading from GB to ICS and rooting,dual booting, flashing, etc.
Only thing missing there is details on the latest updates on cm10 and build 4. In brief, the roms based on these two will not run on earlier kernel versions..coz of the new Mali drivers you mentioned.
Aroma basically makes installing a ROM simpler with the help of a GUI. kinda like the installation wizard you have on windows PCs.
Have a look through the stickies (especially the one on the emmc brick bug) and if you have any questions..always happy to help as best I can.

Everything is pretty scattered even for people who are sort of on the lookout and have tried various newer ROMs.
Dualboot is a feature in custom kernels, at least Siyah that I know of, where you can have more than one ROM installed and choose at boot time which one to use. I gather that its mostly useful for people wanting to try the experimental builds of Jelly Bean and have a stable Ice Cream Sandwhich.
Aroma is an installer which is sort of a second step after a CWM flash, and before an install, and allows you to choose via checkboxes which extra options you might want. This is up to the ROM maker as for what selections you might have. Examples are sometimes which kernel, which Samsung apps that aren't included in the ROM, etc.
I don't know what mali and vsync are but I would guess that vsync has something to do with graphics and maybe with the experimental Jelly Bean builds.
The only really important thing I can thing of is, as always, to do a nandroid backup before starting anything and possibly since you have Gingerbread you might need an older Kernel on hand with older CWM for a recovery back to Gingerbread... This needs to be addressed by someone who can clarify and it might also be necisarry to flash a newer kernel and CWM that will allow you to enter a recovery mode that will be compatible with newer ROMs but I don't know if this is the case or not. Again, this needs to be addressed by someone more helpful.
More important than the above is that, since you've apparently been out of the loop for a while, there's been a bug that can render a hard brick on some devices depending on various hardware components and the version of CWM used for flashing. There's a sticky thread about this but the safest thing way to go about it, as I understand, is to just not flash a 4.04 ROM but use a 4.03 one. I've used both and prefered the options available in 4.03, for my needs, as far as mods go.
Also, as for Jkay's work, some ROMs incorporate that and some incorporate similar features but aren't near as feature rich. As with Gingerbread there's only so many ROMs that he's done the work for and it now requires not just flashing of a framework, as was in Gingerbread, but purchase of the app from Google Play that will allow you to customize the settings. The thread is here http://forum.xda-developers.com/showthread.php?t=1667846
As for theming, its easier to choose a ROM that has it done already and is compatable with Jkay's framwork (assuming you want those things). You can, use a stock ROM, theme it, install Jkay's framework and it will work quite well but its more work. Vertimus themes are very popular but the site navigation is confusing and will definately be daunting. It would be necissary to read first before making any changes (themes or tweaks) deviating from initial setup. The easiest thing is just to choose something, assuming you want it, already themed and tweaked for Jkay's app to work in advance. Wanam builds seem pretty popular for this and as for the hard brick bug possibility with CWM on 4.04 ROMs, you can probably follow the current Wanam build download into his site and find his forum, search for a 4.0.3 ROM (LPG has played best with my particular handset) and make sure its for the SGSII as people often build for more than one phone and it would be a shame to flash an SGSIII ROM (or something else) on accident, for example.
My recommendation, in summary, is not to worry about dual booting or those other things for the moment, do nandroid backup if you intend to upgrade, find out if you need to have older CWM to downgrade (a flashable one at that in case you get stuck at a boot loop) or a newer one to upgrade, then keep it simple and choose an already themed and Jkay tweaked (you'lle have to buy the app) ROM that isn't a 4.0.4 build of Android, but 4.0.3, and to stay with Samsung based ROMs as a starting point. From there you can get a feel for for things and decide if you like the theming or if you want flash something else with stock Touchwiz, if dual booting is worth the trouble, and then bother to read about the other things you mentioned that I wasn't able to answer... so basically, keep the upgrade simple and then go from there and quite frankly if that means a stock upgrade to unmodified Samsung firmware then so be it.
If I backup my rom, cant I just restore it without worrying about the kernel?

As far as I know, you can't restore a GB ROM on an ICS kernel and vice versa.

If they've been updated to run on ICS by the game devs..they will. You'd have yo check that out on the game's page. But since a factory reset is recommended when going from one android version to another you might not be able to save the app data..ie, current state of the game on GB and then resume on ICS.

2.Then search CWM recovery compatible to GB
3.If you found it flash it
4.then restore your backup
