Flashing To Any Rom? - Galaxy S II Q&A, Help & Troubleshooting

hi, i want to change my rom from lighting to Omega ICS V3.1 but i still don get it. this omega rom was XXLPH but my XXKG6. do i need to find the correct version of ROM in order for it to match my phone?

No you don't
Sent from my sgs2 running cm9 using xda app

XXLPH is the Stock ROM that Omega is based on and Lighting is based on XXKG6. With such a difference in the two ROMs I would suggest flashing the stock version of XXLPH first, root it and then flash the Omega rom.
Make sure you read the flashing instructions in the Omega thread first.

that means i can install any ROM even thought the phone is from different country?

No. I would suggest flashing the stock Samsung firmware which can be found in Intratechs thread.
Then Root using the appropriate CFroot.
Then flash Omega
Then flash your black and Blue theme.

Just flash the rom you require according to the instructions on that roms page .
If its ICS based its not stock its a buggy beta leaked test firmware base.
If it is ICS based before you flash find out how to restore to 2.3.6 will save you asking the question later .

For stock rom, i need to look for XXKG6 right? and the version is still 2.3.4

Umm just wipe data and flash? Thats what i do when moving between roms/fw.
Went from checkrom to ics that way.

Like jje said. Backup via CWM before switching roms so you can simply restore and your back as before.
CWM nandroid backup is like taking a snapshot of your device. Saves you a lot of questions and hassles later.

For cleanest new rom do 4 wipes. Only wiping cache and dalvik when flashing newer versions of same rom.
From GB to ICS and ICS to GB I prefer 4 wipes.

[Q] Kernel

Is it ok to flash a custom kernel on top of another custom kernel?
Sent from my GT-I9100 using xda premium
You dont need to revert on the original one before flash another custom. But you need to format dalvik cache and cache in recovery before flashing or you probably have a bootloop.
I suggest to make a backup of the rom in recovery, so If something goes wrong you can enter recovery and have the latest known working rom back in 2 minutes.
Please note flashing kernels always have a very small chance to corrupt your efs partition, its suggested to backup your efs folder before start play with roms and kernels. How to backup the efs, use the search tool of the forum

Thanks for that. I know how to backup efs. Can i just use nitrality instead of ADB? To flash ROMs does it need to be in a specific firmware like sgsl or is it ok to have different firmware from the base of a custom rom?

I know my english sux sry:
Depends on the kernel but usually it is listed in the kernel thread the how to (odin or clockworkmod), clockworkmode is already on your phone if you rooted it with cf-root.
Now, to enter clockworkmod recovery, just push volume up + home + power button until the S2 bootlogo appears, then wait few seconds.
About the kernel type, i always flashed any kernel despite of my baseband, the difference is not so big.
if something is not working, you can always youse the nandroid backup (the backup done with the recovery cwm (up+home+power) and get back to the previous rom with previous kernel.
Im not really in the kernel "how to" someone else can prolly give you more detailed info, but as for me, i flashed ninphetamine 2.05 and 2.1.3 in cwm and it worked.
But.. as always, the kernel developers got a how to install in their kernel thread, so just read those and be sure about if you need odin or clockworkmod, if you are not sure, DONT flash anything until you are sure on how to proceed or wich system to use for flashing, better keep an old kernel with a working phone than have a brick to hold the papers
PS: also almost all the roms on the S2 forum are flashable with the clockworkmod, only few (like the lite'ning) are flashable with odin.
Again, i know im boring, dont proceed if you are not sure, better ask 10 times instead brick your phone

Yes not a problem flash as per the custom kernel instructions .
Kernel can be changed within an individual firmware or custom rom .

Thanks for the reply guys. Coming back to my second question. What if i have KF1 and the rom i want to flash has a base of KI3, should i flash to stock KI3 first before flashing the custom rom or is it ok to flash a KI3 custom rom without flashing first to stock KI3?
Sent from my GT-I9100 using xda premium
The custom rom first, the kernel after.
I got the habbit to boot succesfully at least once the custom rom. If everything is ok i then flash the kernel. Better do 1 task at time.
You can decide to try the rom without change the kernel..and try a different one if you experience battery drain or other problems.

If i am on KH3 and want to flash a custom rom based on KI4 then i would flash stock KI4 and KI4 root first .
Custom rom flashed i will often try a different kernel later .

from my experience
I have found that when i upgraded rom from gingerbread to ics that most custom kernals work with these roms ie now running with xxlpw ics (from gingerbread) with xwlp7 kernal. from what i have read on other posts and threads i could swap kernal to siya or any other as the mega good developers have made them (hotswappable) interchangeable as previous reply said swapping kernal might give you better battery or solve overheat probs.
Eg iwas running darkys rom with siya kernal v?something my phone rocketed temp in short time so i swapped kernal for an up to date one (could have used older one) it solved problem.
Anyone feel free to correct explination im still learning too lol

Based on Xwlp...

Hi,
I m new to root and flashing custom roms and i ve read as many forums and posts as possible, but i still couldn t find out this: if i want to install a custom rom based on ics, do i need to first install and root an ics stock rom? Or can i flash it even from a gb?
And also, if I m using let s suppose ics xwlpg but the custom rom is based on ics xwlp7, both of them 4.0.3, can i flash it anyway? Or should i first install the right ics?
I hope i made myself clear. Please let me know if i did not.
Thanks

To a flash any rom you first need a kernel for your current gb rom that has cwm recovery built into it, such as a cf-root kernel among others. After than you can flash any rom you want, either ics or even gb doesn't matter if its newer or older.
I think this two vedios would help you

Is there any final result difference between rooting the Poland ics or the German one, if i m intended to install a custom Rom after that? I mean will the custom rom completely replace the stock one? Or only part of it?

How to install aosp rom (any) or cynanogen on a 2.3.5 GB spdmod kernel.

Hi i would like to ask how to install any cynanogen or aosp rom on a gingerbread 2.3.5 stock samsung rom with spdmod kernel cwm. Thanks.

i'm a noob. sorry.

With all due respect sir. I can ask this question. I rooted my first android phone because of xda. I also learned how to flash my first windows phone here at xda years ago by asking questions like this one. I'm sorry if your eyes sore when you see noob like me. And i'm asking for specific parameters like android ver 2.3.5 with speedrom . I can't find any posts that match like that one.

i'm a noob. sorry.

Yes clear. So the things that i have to do is
Revert to stock kernel
Apply cf kernel cwm
Install rom aosp or any other?
Right sir? Thanks

Just flash CM9 in CWM. It will also install CM9 ICS kernel so you're good to go. Maybe you'll need to flash another modem in case your GB modem doesnt work with ICS.
After that, I would recommend to flash Siyah kernel, but its up to you.
P.S. DO NOT EVER USE ROM MANAGER (it comes with CM9)

[Q] Help with new ROM for SGS2

Hello all,
I am a super newbee in this field ( please dont laugh ) ! I apologise if i have failed to see the solution for my queries in other threads
I own a Samsung Galaxy S2 I9100 with the following config:
Android version : 4.0.3
Baseband Version : I9100DDLPA
Kernel Version : 3.0.15-I9100XWLP7-CL340913 [email protected]#3
Build number : IML74K.XWLP7
I have already rooted the device with the help of posts on xda. I aspire to put a custom ROM of Jelly Bean in my phone. I have certain questions abt it.
1. Can someone suggest me an apt choice of ROM to suit my current build?
2. will i be able to come back to my stock firmware incase of any problem with the custom ROM. If yes, how ?
3. can i partition my ROM and have to Androids running ? Custom ICS and JellyBean ?
Please help. Thanks in advance.
JB ROMs are still in development stages and need some time to get fully baked.
If you want to try one CM is great.
And you can return back to ICS anytime.
To dual boot JB and ICS you need to flash Siyah kernel.
I would suggest you to flash (install) CM9 for few days. Bcoz its better to be using known stable build for regular use. You will get an idea of what to expect of AOSP ROMS and what are their limitations.
Then you can plunge into exciting world of flashing nightlies (less stable) builds.
You can always go back to default samsung roms if CyanogenMod roms dont suite you. There are lot of custom Samsung rom based roms to choose from with very good customizations.
But before you do any flashing of rom, BACKUP YOUR CURRENT ROM.

Better flash Siyah first...

[Q] Unsure about flashing new rom

Hey.
I'm looking to flash my pretty old Galaxy S2 from a custom GB rom to one of the spaking new JB roms.. the only thing is I'm not sure if my phone is updated enough to support flashing the new roms?
The particular rom I am looking at installing is SentinelROM v4.75
http://forum.xda-developers.com/showthread.php?t=2268064
The instructions say:
If installing for the first time:
To install this ROM you will need to have an unlocked bootloader and a custom Recovery such as TWRP or ClockWorkMod installed (personally I recommend TWRP, I have had issues with restoring backups using CWM).

What I currently have on my phone is:
CheckROM RevoHD V6
Baseband XXKI4
Android 2.3.6
N.E.A.K Kernel 1.4.2x with CWM v5.0.2.8
Am I good to just load the ROM onto my sdcard and just flash away or do I need to update my phone to a JB stock rom first? I'd ask this question in his thread but I don't have enough posts apparently..
