Do you need to Root to install Lightning ROM? - Galaxy S II Q&A, Help & Troubleshooting

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.

[Q] Would you recommend Infusion ROM?

Hi guys, Just got my sgs2 and was looking for a good, stable, rom being close to asop and having little or no samsung bloats helps. Infusion showed up in my search and it seems to have just what I need. I just want to know what people's general experience has been like (trying to look before I leap ). I used darky on the sgs1 which worked quite well for me. I would really appreciate it if you guys can share your experience with infusion rom. and if there are any other rom you can recommend.
Also I currently have my sgs2 rooted with a custom kernel on stuck rom, which for the most part works very and is damn fast and snappy. Do you think having a custom rom would make much difference? Thanks in advance
Yes, it is without a doubt my favourite rom. Very stable, improved my battery life and has everything a custom rom should (deodex, CWM, root etc).
At the end of the day though, try it and see. If you don't like it you can always download your stock rom and flash it back, or even try another custom rom like VillainROM or LightningROM

Cool ROM?

So uhhh, my boyfriend got me this phone a few days ago and I want to get a custom ROM on it. He's in alaska so he can't help me out for 14 more days, so Im here. Umm, well I just use AIO Vibrant toolbox to flash back to stock, so it's eclair I guess, not sure what that really means but thats what my phone says.
Then I rooted it, and it has superuser.
So what do I do now.. can you guys recommend me a ROM and help me install one? Like.. whats a good ROM, and.. what do I need to do. Do I need to update to froyo, if so how do I do that. Sorry Im such a newbie at all this, I hope someone helps me out!
Yeah and also like, I would like a ROM that looks awesome and is good for battery. Just an overall awesome popular one. Please if possible help me, or give me instuctions on like... installing it, I literally don't know diddaly squat about installing ROMS, I just wanna do it
the easiest way to install a rom would be to download rom manager. If you're gonna stick with froyo (which I recommend since its a lot easier to install and is better with battery), you won't have to get premium. after downloading rom manager, open it and select flash clockworkmod recovery at the top, then select galaxy S vibrant (make sure you select just vibrant NOT vibrant (MTD)). After that select reboot into recovery, if you are in CWM recovery then you can go ahead and reboot, if not, then select reinstall packages. It should then install CWM recovery and bring you back tot he same screen, select reinstall packages again and it should bring you to CWM recovery. After that go ahead and reboot, then go back to rom manager. Now you can go to download rom and select a rom you would like to install. I highly recommend project V or bi winning. Good luck!
I would recommend to flash a rom with rom manager. Its the easiest way to install any custom rom. You may have to vet the premium version for it but is so easy you can mess up.
I would recommend trigger project v or even trigger 3.2. Its fast and awesome.

I would suggest that you learn how to use Odin first before flashing a custom rom to your phone. Learn how to go to download/recovery mode. This way you know what to do in case you soft bricked your phone.
Then just flash in rom manager like what they said.

Oh and one important thing that the guys forgot to mentions above, Rom Manager is in the market, so yeah, and I would suggest you flash Bi-Winning V3 Rom

You are incorrect sir! Simply honey and revolution rom are better and faster than most froyo roms. I know because I've have tried them all. As for a froyo roms they are all decent and should try one of those before you move to gb. Warning flashing roms is addictive once you start its hard to stop. Good luck.

I recommend Bionix 1.3.1. It is known for its stability, and I feel it's a great rom to start off with. Novices and experts at flashing use it from what I have read in the thread. Also, it has decent battery life, but you can flash a new kernel (like Bali UV (undervolt)) which has showed to save battery life. I will put both links below for you to take a look at. Most of the time the instructions to install a kernel or rom are in the original post, however as stated you can flash through rom manager. If you want more in-depth details on how to install them, you can pm me, or I can post them here also.

Agreed, that is the set up I currently am using, I flashed a couple days ago and haven't been getting the battery life that others are claiming to have but the rom is really good. I've tried several of the gb roms and they are way to buggy its not even worth it.

Try Batista70 2.4 + speedmod kernel K2-16...
Allow me to quote myself:
oinkylicious said:
It gets asked all the time, and as one might expect, you'll just get replies from people saying "I use x ROM with y kernel and I recommend it because z".
There is no suitable answer to your question, instead I would recommend you take a deep breath and have a read through what's already been written and decide for yourself what to pick.

i saw two CheckROM:

http://forum.xda-developers.com/showthread.php?t=1312240
what are the differences between each other?
I have been using VillainROM for ages now, have tried the rest but keep going back to VR. Best battery and closest to stock (I don't normally theme).
However, your question is a bit subjective, everyone looks for different things in a ROM.
Best way is to try a few and see which you prefer.

Newer one(v2.0.0) has updated firmware, latest Jkay pack, more mods basically the one you should get

Try Batista70 2.4 or 2.5. the best of the best!
I suggest you learn how to flash and try out a newer deodexed stock like KJ2, then start flashing customs if you don't like the behaviour of stock roms. Usually stock are very good with the right kernel.

Hardcore's SpeedMod K2-15 is pretty sweet. Give it a search up top ^
In my opinion HyperDroid-Androidmeda is one of the best ROM's
http://forum.xda-developers.com/showthread.php?t=1288850
For sure it's worth to try. Some people were able to get over 6h display on this ROM
I recommend checkrom revolution v1 with cf root or speedmod and bigbanghds ICS theme. Looks nice, fast, good battery, mostly stable.

so the steps to flash my galaxy s2, are:
1-first root galaxy s2
2-then backup efs

We do not allow "best rom" threads because there is no answer to the question.

First time android user (roms and themes)

So I finally made the switch from iphone to an android device. With the Iphone you would jailbreak it. Im guessing here, you would root it and then install a rom?
What do I do if I want to install a rom and then a theme?

First of all u need to root ur device, after this u need to install/flash a kernel with the cwm recovery (u can use easily one of the rooter kernel.made by chainfire), then u can flash the rom, kernel, theme, whatever u want/need directly thru the cwm.

My advice would be to read the threads on the many kernels avaliable all have instructions on how to install... Then when you feel confident make your choice and get yourself rooted. After you understand the process and familiar with CWM and what it is used for use the same process to choose a ROM... Good Luck
In all honesty, I tried loads of roms on my s1 but I have not felt the need for it, or indeed seen any benefit to a custom rom yet, and certainly not one that will out weigh the inevitable bugs in them.
Clockwork rom bootloader is excellent for full back up and restore purposes. Frankly however with this device rooting is enough especially now there are one click solutions for it.
Once rooted there isn't much you can't change or customise. Camera apps, hacked launchers etc
Personally I have found this far more stable and much more interesting than simply installing someone else's work.
OH YES WHILST I REMEMBER FIRST THING TO DO ONCE ROOTED IS BACK UP YOUR /efs FOLDER IMMEDIATELY THIS IS ESSENTIAL!!

Ok so ive been reading the threads and rom section.
I only have 2 question left. My phone atm is on android 2.3.3. In the root thread, I want to get 2.3.5 KI3.
Can I flash the KI3 right away or do I have to update my phone to 2.3.5 and then get the 2.3.5 KI3?
Is Firmware and Modem the samething? I see there both I9100XXKX#
Once I do that, I will root my phone, install cognition rom and then the ICS theme.

I wanna suggest to u the XXKI4 (2.3.5), this is a superb firmware, u can flash directly to this version without any trouble, for the other question, no firmware and baseband/modem are two different things, u can try many basebands cause there are some basebands that works better with ur specific carrier.
So, u should root/install cwm and than cognition and theme.

A few questions

I search the internet and i could not find the proper answers for this issues.
I managed to install Pound Rom on my phone, the stock rom banished, and i get a lame battery life( i know i know it depends on users). I am not doing anythin with my phone and it drops 3% per 100 minutes. Any suggestions?
I saw that you can use roms with Kernels, i saw a post with "what is your fav rom+kernel combination", what if install a rom and then apply a kernel which is incompatible? Will i brick my phone or just the rom? I will be able to reach cm to reflash another rom?
And if i installed a rom+kernel which are compatible, after deleting full data, wipping, and so on, it is ok to install a new rom and a new kernel without bricking? It is ok to wipe and go to stock rom from odin? I saw a couple of guys bricking their device somehow like that..
If i install stock i will get the exact performance like i had before, good battery life etc?
And how can i get TWRP recovery on my phone? I saw posts where devs said 'or use twrp recov' i googled and found an app on the play store which told you if s2 is compatible aaand it was not and that was like the only thing i found..
Sorry if my questions were answered somewhere else and i would appreciate if in any form you would help me

firstly threads about best rom kernel etc are not allowed still omega and cyanogen rom are the best
incompatible kernel MAY BRICK YOUR PHONE (chances are less but atleast it will cause bootloop)
you can always switch you rom(including stock rom by odin) by wiping data and flashing a new one
you will get same performance as before
twrp depends on which rom you are using prefer cwm bcoz its most compatible
Thanks for prompt answer!
