My question may be easy but I can't understand this...I had vr 2.1 and went to vr 2.3 by flashing the Rom through recovery mode.all ok.then I installed Ninphetamine kernel 2.0.2 but then I lost root access.is this normal or did I screw up something?after losing root I flashed with odin cf-root and now everything is ok but I prefer Ninphetamine...any help?

You probably need more than Ninphetamine's kernel to get root. (I have no clue about this) But Cognition uses the Ninphetamine kernels too and it works just fine. Maybe they're incompatible with VR?
The way I understand it (each phone manufacturer seems to be different) is that the kernel frequently blocks either access to root, or the installation of specific files.
To have root, you need the su executable, and an apk which allows applications to ask for root priviledges. Both of these are stored in /system, and are not part of the kernel. However, in order to install these, you either need to re-flash a ROM with them pre-installed, or install a kernel and other files over the top of your existing rom using ODIN.
Flashing a new kernel may remove recovery (CWM), but doesn't (as I understand it) affect root. Some kernels are incompatible with certain ROMs though (I'm still on the stock kernel)
Now you have root again, try re-installing the kernel (point CWM app at the zip file did it for me)

It seems CF-Root v4.1 is the bees-knees when it comes to rooting the Galaxy S II, but unfortunately it is not ROM Manager compatible.
Is there an up to date method to root the SGSII that works with Rom Manager? I found this link: http://www.inspiredgeek.com/2011/04...ng-odin-and-superoneclick-step-by-step-guide/ but I suspect there may be a newer method.
Here are my phone details, just in case:
Android version: 2.3.3
Baseband version: I9100XXKE7
Kernel version: 2.6.35.7-I9100XWKF3-CL276555

Why don't you just install ROM Manager, then download latest clockwork recovery using ROM Manager?
It will then be ROM Manager compatible.
Because I need to attain root before I can flash clockworkmod. ROM Manager says "An error occurred while attempting to run privileged commands"
I'm on the original galaxy and the easiest way I've found to root is to use odin or hemindall to flash a kernel with cwm. It roots and gives cwm in one action. Also theres a new super one click that I've had success with on many different brands of phones, hts, lg, moto

What I meant is, why don't you just flash CF-Kernel, then install ROM manager, then use that to install clockwork recovery.
There is a confusion that rom manager is not compatible with the kernel. That part is not true, rom manager is not compatible with the clockwork recovery that is supplied by the kernel, you just use the clockwork recovery that can be installed with rom manager. The cwm app is not compatible with the recovery installed by rom manager.
Flash codeworkx kernel, root it, and run rom manager to your hearts content.
I'm having this issue too.
I've spent most of the day trying different things.
Regardless of how I root, and what rom and kernel provides the base when I try and update cwm through rom manager then try and reboot into recovery through rom manager I get the failed to verify error.
I've rooted with the chainfire root, with codeworx kernal and then superone click, and it's made no difference.
I've also tried it from rooted stock firmwares, and custom roms.
Still cannot boot into recovery from rom manager.
I've also noticed that despite rom manager saying that I'm using the latest version, when I manually boot into cwm it shows the previous version.
edit: I even went back to stock and rooted using link in first post, then installed rom manager but same error.
Keeps going to 3e system recovery
God it's annoying
Further googling has led me to believe the issue is rom managers not being compatible with 3e recovery.
Apparently we need to have 2e recovery.
Any way to get that?
edit: Or can we disable signature verification in cwm?
re-edit: Well I found this in the cf root thread which will explain why I will never get rom manager to work
CF-Root includes a custom version of CWM4. I always make custom versions, as the originals often do not take some Samsung specific things into account.
CF-Root/CWM4 is NOT compatible with ROM Manager! Manage/perform your backup/restores from CWM directly or using the CWM Manager application included with CF-Root
Where is the standard version then?

Codeworx said himself that his kernel won't work with rom manager.
If anyone is able to install roms through rom manager I'd like to know what rom, kernal, and how they rooted.

Haven't read that thread but i thought that was the whole point of his kernel, oh well.
Well I finally found a fix.
This time I can boot into recovery from rom manager.
No more failed to verify errors
What you need is this version of clockwork recovery

Flash it with odin, then use superoneclick version 1.95.
Hello everyone. There is one thing that I'd like to know before going ahead and rooting my gs2 (cf kernel).
That kernel installs the CWM recovery. Assume that I'm on stock KI4 now, then root it. If a new fw is released, and I'd like to move to say KJ1 frankenstein from intra, how should I flash that? Should I still use the same procedure that I've always used until now (odin), or should I flash it via CWM?
Also, what are the impacts of moving to the newer fw? Do I lose root and also the CWM recovery?
Thanks,
TD
Anyone?...
Yes, CF-Root installs CWM recovery, Superuser and enables root. So it's a super easy thing to do and very convenient.
If you are rooted and is on KI4, moving to a non-rooted frankenstein build(that's what you wanted), you will definitely lose root because the firmware is stock.
So if you flashed a stock frankenstein build, you will lose root AND CWM(loosing CWM will give you the stock recovery, which doesn't do much). You would need to flash a rooted kernel(e.g. CF-Root) using Odin to regain root. Depending on the firmware also, sometimes your data is wiped.
To preserve root, I recommend you to flash a rooted custom ROM. VillainROM is good to start with because it is close to stock. The closest to stock in my opinion is to root it with CF-Root. Feel free to experiment with custom ROMs.
With rooted custom ROMs, you will stay rooted when you flash them VIA Clockworkmod revovery.
P.S. Be sure to always do a backup in case something goes wrong! Do a full ROM backup via CWM so if anything happens, you can just revert.
Hello everyone,
I have SGS2 with latest stock firmware (XWKI4) for my region.
Now, I would like to start playing with it with roms and such (yes, I already have Jig just as safety net), however I would like to creat as close as possible original configuration.
Now, I have rooted the phone with zergRush by Doomlord sucessfully and made efs backup as well as kernel image backup via HC-kTool. (This is kernel image backup right?) This way I presume I got pretty much untouched kernel image except rooting, right?
What now I would like to do is to make ROM backup and install some recovery. I know that Clockwork that comes with Rom Manager isnt exactly the same as Chainfires CW that comes with CF-Root and I know that Chainfires CW is optimized for Samsung phones (not to mention that they are not compatible with each other).
I guess my question would be is above that I did make sense, and shall I install CW from ROM Backup or get some CF-Root kernel with CW? I mean what do I lose with each solution, or any other advice how to complete ROM backup so that I can recover it if something, God forbid(knock on the wood), gets fishy?
Cheers

If you take some time and search different threads in xda developers forum, you will find many user posting statements not to use ROM manager.
As I do not use ROM manager at all, I did not read the whole posts. That's why I do not exactly know, what the issues are about ROM manager.
(Incompatibility with many ROMs and kernels, but there must be more issues.)
I am using CWM Manager app (included in Chainfire's CF-Root kernel) or CWM5 recovery mode to create a complete system / nandroid backup.
So, in case of an emergency I only have to flash a kernel containing CWM5 recovery and restore my last system backup.
Just to be on the "safe" side, I also copied my efs folder to my external sd card.
And all my apps (+ app data) are under Titanium Backup control.
So, I recommend to use plain CWM recovery backup.
If you are not sure about ROM manager, please search the forums and make up your own mind.
Good luck !
So basically, I can instead of Rom Manager install DarkyROM2 Tool, flash some kernel with CWM support e.g. Hellcat, CF-Root, and boot to recovery and make backup of current rom(with higher compatibility), right?
Sorry if this is obvious, but I have just started with this kind of tweaks...
I have installed CPU analyser, and with stock ROM I think the slowest it goes is 300mhz, WIth a modded ROM it slows down to 110mhz. So I'd like to use modded kernel with stock ROM (I've found no ROM's to be as quick or stable as stock)
Is it possible to have stock LK1 firmware, but with rafa's modded kernel? My procedure is
1) Recover LD1 firmware with ODIN
2) Reboot update LK1 in KIES
3) add super user. Boots, make calls etc
4) Apply kernel and modules. Boot and lost IEMI. I have tried restoring IEMI from my backup in galaxy toolbox, rebooted. But it still doesn't work.
Am I doing something wrong, or does the stock ROM not support modded kernel/modules in anyway?
Also if I do get it working, do I need some kind of CPU/battery saver or are the routines built into the kernel, no other apps are needed? I tried one app, it seems to work but it keeps on popping up with a message that it's using superuser priv, so it's quite annoying.
flash modules of kernel after flashing the kernel without rebooting in between!
this way u won't loose imei!!
whenever superuser permission message come up, there's an option below to remember the choice, click it and then message won't appear again!
ah so flash kernel, then modules without rebooting? I'm pretty sure a couple of guides say flash kernel, reboot (go straight back into recovery) then flash modules.
which specific (filename) kernel and modules to use with stock LK1 ROM?
201303051129-E3-boot.img
and
201303051129-modules
did that, emergency calls only! arggh
Try flashing modules after reboot.. Flashing modules should solve imei problem!

Would the following work as a way to try out, for example Cyanogenmod 10. I am currently running a 4.1.2 install (pretty much stock just rooted/cwm via Philz as per the tutorial). I have a complete backup made via Philz recovery of this rom along with the kernel (which I believe is still stock from that) and efs.
1) Install a custom kernel (eg. dorimanx 9.x?) via the Philz recovery.
2) Install cm-10.2-20140102-NIGHTLY-i9100.zip.
3) To return to the original rom, reflash the original kernel (with whatever CWM is included in dorimanx) - then reflash the backed up rom via the same recovery?
I hope this is clear enough a question.
I believe you have to flash a stock rom through Odin, to return to complete stock. Just flashing a stock kernel isn't enough, and is surely not going to work (so don't do it).There are also tutorials how to remove the yellow triangle afterwards.
Please correct me if I'm wrong

This is the part I'm most unsure of. Ideally I'm trying to figure out the process that lets me go from CM10.2 (and whatever recovery) to the point I am running the backed up rom rooted with PhilZ-cwm6-XWLSW-XEU-5.06.1-signed.zip again. Very confused on how to do so.

Topher,
If you have rooted and cwm via philz, you already have a modified kernel installed. I believe the philz-cwm6 should be as close to stock kernel with the CWM incorporated. You don't need to add another kernel, because it will be replaced when you install the custom ROM. You should just be able to flash the cm10.2 via philz or via odin. You can then flash the dormanix kernel if you want - can't comment on that kernel - or if it has cwm included.
I would also suggest that you consider backing up you /efs folder (one with you imei information etc) prior to flashing any custom roms. People have been using hcKtool to do the backups and also an actual copy as well.
Depending on the custom rom, you may have connection problems with your network. So you may want to consider keeping a copy of your modem.bin file from your stock rom handy in case you need to flash onto the custom rom.
If you want to go back to stock, then you just need to flash the stock rom - you can check sammobile website for your stock rom or use the backup that you made.
I should point out that I have yet to do any of the above - I gathered this from reading the forums. Some more experienced forum users can add corrections. I rooted my phone a couple of months ago and now considering installing custom rom in the next couple of months.
Thanks.
if u flash a custom rom (cm10.2 for example), it already included kernel as well. so if u want to try out other custom kernel, i can flash it after you are done flashing a custom rom but make sure it is compatible with your android version. (u cant use custom kernel that not support android 4.3 with a custom rom running android 4.3)
