Im thinking about change my rom to Cyanogenmod, but Im afraid it will crash and brick my phone.
Can i just flash it directly? or should i wipe out all stuff first?
Speedmod is a kernel, Cyanogenmod is a ROM.
CyanogenMod 7 (w/ Gingerbread 2.3.7) for Galaxy SII Q&A.
No, ist very very unlikely to brick your phone just because you go from stock (or modded stock) or whatever to Cyanogen,
If something goues wrong, you can (nearly) always flash a stock Firmware via ODIN.
As far as I know its almost impossible to brick a modern Android Phone. Except you do do some really "deep" stuff.
But you should wipe your phone when you go from Stock (or modded Stock) to Cyanogen.
And you should flash the Cyanogenmod Rom twice because its using a new or modded version of clockworkmod.
There is a step by step discription in the Cyanogenmod Wiki.
I hope that Information helps a bit.

1.just download latest nightly of cyanogemod and put it on SDcard...Link for latest nightly here: (http://download.cyanogenmod.com/get/cm_galaxys2_full-94.zip)
2.enter CWM recovery and do a wipe data/factory reset,,, wipe cache,, wipe dalvik cache(it is in Advanced option in CWM main menu)...so yes wipe out all stuff first
3. install nightly .zip file from sdcard
4. install nightly .zip file from sdcard AGAIN...REALLY DO IT OR IT WILL NOT BOOT
5. reboot phone from recovery and you will be in CyanogenMod 7 ROM
PS: do not be afraid about SpeedMod kernel....flashing cyanogenmod nightly .zip also flashes CM7 Stock kernel for you
PS: You can try Siyah kernel 2.1 beta 14 (http://www.gokhanmoral.com/public/files/siyahkernel/test/Siyah-v2.1b14-CWM.zip) info here: (http://forum.xda-developers.com/showthread.php?t=1263838)
I am using this kernel since beta 12 and no problems
PS: Speedmod is name of kernel = core of android system...Cyanogenmod is a ROM = phone firmware
You can ask me again if needed..or send me a PM
Should he not at least make a nandroid backup first
Dude, do some research.
If you managed to get Speedmod onto the phone, then you shouldn't have any other problems.

so, I've had my SG2 for like a month now, rooted and all, but the problem is , i can't flash any other ROMs(but stock ROMs) or kernels (except for CF root,stock and siyah kernels ) on it via CMW... each time i tried to flash anything, i end up stuck at "galaxy s2 GT-I9100" boot-up logo.... I've tried flashing CM7 then i got the boot-loop ( even with double flash, or triple didn't work for me) and i can't get into CWM when i got the boot-loop....
someone please help me.. i read alotta threads and none of them got similar issue like mine...
i guess its true what they say : every galaxy s2 is different from the rest.
Hmm....must be something you're doing wrong. Nothing to do with Galaxy S2 being different.
Have you always followed the dev's instructions while flashing roms?
Wiping data, cache? Matching up the kernels and roms?
As far as I know, there hasn't been a single person who completely failed to install VillainROM on their SGS2.
I would advise you to give it a go.

What ROMs have you tried to flash?
If you're tring to flash AOSP ROms like CM7 or MIUI it's normal if you're not doing it with a comatible version of CWM. For example, cf root kernel installs a modified version of CWM on your device, which is not compatible with CM7. IF you want to flash CM7 first you have to flash codeworkx kernel http://forum.xda-developers.com/showthread.php?t=1118693, and then enter recovery (the new CWM installed with this kernel) to flash CM7.
Now if you can't flash samsung firmware based ROMs (villainROM, Leomar Revolution, Batista...), I don't know what it could be. I never had a problem flashing samsung firmware custom ROMs with the cf root CWM recovery.

If your phone has cf-root/kernal and cf cwm can you just flash over top codeworkx's kernel and do you have to re-root?

I used to use VR 3.0 but could only work with stock kernel or cf root kernel has never booted with the ROM's kernel..

My phone came with CM7, but i flashed it with rooted stock coz i wanted to have a feel of it... but now i'm done with it but i can't get any roms to work... so frustrating.
i literally have tried flashing ALL Roms (ligtnung, gingerbread,vr, cm7), during the 1st few days that i got my phone it worked with VR 2.5 and 3.0, even MIUI.. but after i flashed with some Asian stock ROM via odin... nothing would work through cmw anymore...
i seriously don't know what i did wrong...
btw, right now im using basebad ver: I9100XXXKI4, kernel: 2.6.35.7-siyah [email protected]#20, build number GINGERBREAD.ZSKI3.
I really don't know. YOu should try to go the closest possible to stock and try from there. DO a full wipe, wipe data, wipe system, everything and flash a stock ROM from your country and carrier (there is a thread from infratech where you can get carrier specific ROMS). THen connect your phone to kies (maybe yo get an oficial update) and then do everything from scratch, root, install CWM, etc...
That's what I'd do but I really don't now if it's the best option.
i have almost the same problem,but me i can flash any rom,but the problem is with the kernel my phone refuse to boot on any other kernel else than cf-root and the speedmod,it freezes in the kernel loading so i must turn it off and reflash via odin cf-root or speedmod to get it works again.

well, i'm gonna try that and see if it works, am also goin' try to see if downgrading to 2.3.4 or something would work too...
but please if you got any more ideas, just keep it coming..
thanks
Phew! NOW I HAVE CM7 RUNNING ON MY PHONE!!
I'm gonna try to explain how i fixed my issue, as clear and explanatory as i can..
lucky i didn't brick my phone during all this, because I tried so many things and none worked.I unsuccessfully tried downgrading to XWkI4, ZCKI4, and alot others via Odin... after flashing all i get is tons of error messages(on 3e recorvery) E: can't open/cache or E:failed blah bla bla to load /efs... i thought OMG! my phone is bricked! then i recalled reading somewhere that flashing the 3 tar (PDA,MODEM,CSC) files usually should work(maybe better than flashing a 1 tar file), so i found a 3 files xxKI3 rom, flashed it and BAM! it booted up this time without any error. so now i went ahead and rooted it since the tar files came unrooted, then went into CWM to flash cm7 ROM, flashed it twice and ofc i got stuck on boot logo.....i didn't panic much, i pulled out the battery, and restarted to CWM where i cleared cache/ dalvik/ and did wipe/factory reset, then i reflashed CM7 again (twice) and it worked!!!! YES, CM7 is fiannly working on my SG2!
thanks for everyone for helping, and i hope this can help others on the same boat as me..
Hello,
I am really a beginner with flashing roms and I just flashed my first CWM and CM 10.1 rom.
But the version I chose has a few bugs, so I want to flash a different CM version. should I do it the same way as I changed from the stock ROM to CM 10.1, by moving it to root path and then via recovery choose install zip from sd card? What I also don't know is what will happen with the GAPPS. I flashed it right away the first CM flashing. but will I need to flash GAPPS again?
Also, If I want to change from non-touch CWM to touch-CWM, I do it via Odin in the same way I first flashed the non-touch CWM? Will that over-write the existing CWM?
Sorry I am really a beginner, but at least I flashed the first rom
Thanks to everyone who helps :good:

Yes, all you said is the correct way. Its that way itself.
To sum it up, if you want to flash a different CM, reboot into CWM recovery, Wipe Data/Cache/Dalvik cache and flash the zip package and flash the gapps and do a wipe data/cache/dalvik cache again. Yes you need to flash GAPPS each time when you install CM.
For changing recovery, if you have another version installable via Odin, then you can go on with it, and it will replace your existing recovery.
Be sure to check this Table to know which GAPPS should be installed for which CM version.
Happy Flashing!
Is it possible to upgrade CWM on my S2 or are the particular CWM versions matched to particular kernels, like Samsung stock or CM? I am running NeatROM with Philz kernel, which uses CWM 6.0.3.7. I see there is a newer versions of CWM that can be flashed which is KK compatible (thinking about giving Cyanfox a whirl in near future). Thanks.
Recovery is baked into the kernel on the S2, so any recovery you flash independently of it will only persist until the next reboot. If you want a particular CWM version permanently, you'll need to run a kernel which has it.

Thanks. That is very helpful to know. So if you "temporarily" flash the latest CWM for kitkat in order load Cyanfox, then does Cyanfox reinstall the CM11 kernel with the appropriate permanent CWM for kitkat?

downlaod the CM11 kernel, flash it via your current one, wipe data/factory reset from the new kernel, wipe system too just incase, and install cyanfox and its gapps.
I'm planning to use Custom ROM for my JB using Custom Kernels from my Rooted ICS, and I have questions and doubts. Here's the steps and the Q's they have:
So, here's the steps I planned based on my S2 Guide Surfing:
1. Root my ICS (Done)
2. Flash Stock JB Official Firmware via Odin XWMS1? XWMS2? or XWLSW?
Questions Regarding This Step:
A. Do I have to backup my /efs folder from ICS here?
B. Do I have to Wipe Data/Factory Reset + Wipe Cache BEFORE/AFTER flashing the JB Firmware?
3. Flash Siyah? or DorimanX? Kernel via Odin
Questions Regarding This Step:
A. Can I run these kernels on my Stock JB ROM (if succeededly flashed)?
B. If I do a backup on Siyah via its CWM, and changed to DorimanX, then noticed that the kernel's not my type, can I restore my backup from Siyah's to DorimanX's CWM? Or does the both kernel have the same CWM?
4. Flashing Custom ROM via Custom CWM
Questions Regarding This Step:
A. If I flashed a Custom ROM which has a Cusrom Kernel inside (like NeatROM, I suppose), will it be overwritten my Siyah/DorimanX kernel? Or they will still be there?
Thanks for Noticing My Questions! And Very Thanks for Answering Them!
1) Yes, I'd backup up EFS immediately after you root your phone (and even before you do a nandroid backup with CWM). Use Hellcat's kTool from Google Play (and buy Hellcat a beer after you download it).
2) No. No need to wipe when flashing stock firmware (you can if you want though if you like a really clean install) because you're going to be wiping before you do a custom rom install anyway.
3) Yes. You should be able to run Siyah or Dorimanx just fine on stock JB (make sure you choose the right build though; read the threads devoted to these kernels to work out which build you need).
4) Yes, if you do a nandroid backup with CWM while running Siyah, and you switch to Dorimanx & decide you don't like it, you can restore your backup & go back to Siyah.
Though you could just easily re-flash Siyah with CWM to achieve the same result. That will probably be quicker than restoring a backup (say, 2 minutes Vs 10 minutes). If you re-flash a kernel, just the kernel changes, none of your settings/apps/anything else does, so restoring a nandroid just to go back to a particular kernel is overkill.
5) Yes. If you flash a custom rom, the kernel bundled with that rom will overwrite/replace your current kernel. If you don't like the kernel bundled with the rom, you should be able to use any other kernel you want with it provided the kernel you want to use works with the base of the rom (I.E the kernel you want to use works with TW roms if you're running a TW rom, or AOSP if you're running an AOSP rom) & the Android version of the rom you're running. Again, read the thread devoted to the kernel to determine compatibility before you flash it (worse thing that can happen if it isn't compatible is the phone will bootloop though; unlikely to brick your phone outright).
Hey folks,
I'm desperately trying to get a CustomRom working on my GP4.
I'm relatively new to the device, but not to CustomRom's, since I was using a Motorola Defy untill last summer, running CM7.2 and CM9, MIUI and a couple of others.
So here's my issue:
I flashed the Terrasilent Kernel in order to get CWM so I could flash the .zip's from there, as some weren't available for odin.
The kernel works fine, but as soon as I try to flash any CustomRom (I tried CM9, CM10.2, Hydrogen and the PACMAN Rom), I'm just getting infinite bootloops.
I also tried flashing with SD card removed, SD card back in....doesn't help. No matter whether it's done with odin or CWM.
Mostly I get stuck at the Samsung screen , the PACMAN insert coin or the Terrasilent phonebooth .
Does anyone have suggestions how I could make it work?
Cheers!

Did you wipe the data/cache? Also, I believe you're supposed to flash then ROM first, THEN you flash the kernel.

Forgot to mention that: I tried various ways: first wipe data/cache, then flash ROM; first flash ROM, then wipe cache; wipe cache, flash ROM, wipe again...
In order to get CWM recovery and being able to flash a zip I flashed the Kernel first. For CM9 I followed this http://forum.xda-developers.com/showthread.php?t=2213152
As I couldn't flash any of the pre-flash zip from stock, I thought it's necessary to flash a kernel including CWM first. It was done in the same way in some youtube tutorial I watched, where the guy already had the terrasilent kernel on his device.
For odin, I will check if it works with first flashin the ROM and afterwards the kernel.
Cheers for your fast reply!
