hey all
my note is on ics 4.0.4 stock rom and notecore v14.1 kernel
i did a backup with cwm recovery and it was done correctly to my sd card
the question is:
if i install any other custom kernels,will the cwm recovery version change??(i think yes, am i right?)
and will that affect the restore of the backup that i made with the another version of cwm recovery if it was changed??
thx in advance

Yes, the cwm recovery version might change but it should not affect the restore of your backup.
Nope, it shouldn't. Your version of CWM won't change unless you change it. When you flash a custom ROM, it changes /system and /data to name a couple. Your recovery doesn't get touched.

thx for both of u
but if i want to change my current custom kernel which is notecore v14.1 to another custom kernel such as PhilZ-cwm6 v3.72 ,should i do extra procedures or just flash it through pc/mobile odin or cwm recovery normally without any other steps??
As note 1 has the recovery built in the kernel, any change of kernel will change the recovery to what is included in the new kernel. This will not affect your backups. You can restore your old backups with new cwm. No special procedure, use mobile odin or cwm, pc odin will give you yellow triangle, increase counter.

Rooted+CWM installed in your phone?
Use cwm recovery to backup your stock rom.
Root your phone, instalar cwm and do a backup.
To restore it you need first to convert the file System to rfs, and then restore the backup through cwm. This is because custom roms use ext4 file system and if you don't convert it, cwm won't restore your backup.

Well, if you are going to use cf-root ext4 manager to restore a stock backup its probably recommended to use cf-root kernel, and you will lose the custom rom you're using, so why do you care if it's just the app or the entire kernel?
I don't know if just the app will work, but it's irrelevant. Just Flash a custom rom with cf-root applied, or Flash the cf-root kernel, convert to rfs and you're good to go. You'll restore a backup and basically wipe any custom rom you were previously using.
Otherwise, a Odin one package will revert your file system to rfs, and wipe cwm recovery (so you need to root and istall cwm afterwards and then restore backup)
1. Root your phone
2. Install CWM
3. Backup your Current ROM*
4. Install yuour Custom ROM, and if something happen
5. Flash Stock ROM with odin
6. Root your phone
7. Install CWM
8. Restore your Current ROM*
Make sure you didn't wipe anything in your SD card..

Ext4 Manager app will convert your file System to rfs, so do it before restoring backup.
The other way, Flash a Odin one package, root, install cwm and restore.

Its not the cwm recovery, this message is for the cwm manager installed as app, it comes with cf root kernels. You can still use it but not fully functional. And you still have cwmr flashed by hydracore. Go to recovery mode manually or use this cwm manager to boot in recovery to confirm.
And did you earlier flash cf root kernel on CM rom?

As far as i know cf root kernels are for tw roms only. Now since you are on hydracore then you should have cwm recovery installed with it, did you check it? Just ignore cwm manager or remove it using titanium.

Rescan the backup folder of your titan backup

If one flash CF root kernel and later update to hydracore, kernel will replace but CWM remains still. Just delete it with titanium/Syst app remover or same other.
I rooted my device and I want to flash the CWM is it okay to flash it through ODIN right now? If so can you provide me the .tar file to install the CWM and at last is it correc that the CWM can make a full system backup because I wanted to flash the CM10 nightlies (I do know that to flash the CM10 I must have flashed the CM9 first) and some people said the CM10 isn't really good and I wanted to backup my system so if I didn't like the CM10 I can go back to my stock android
What rom are you on?
You will need to change the kernel to get cwm. If you are on rooted ics, you can install speedmod or philz kernel to be safe and get cwm.
Then you can make a nandroid backup and install the cm rom. No need to change the rom to cm9 if on a safe kernel.

what the kernel you have on the phone?
there is a possibility to use cwm temporarily. so u don't need to flash an other kernel:

Yes but install a rom using that may prove dangerous if the rom has bad updater script. This can be used to install a kernel.
Hi everyone!
Maybe I have a basic doubt, but because I don´t understand, I like have clear this. Yesterday I decided root, replace the recovery and install a custom rom on my Note (N7000). I choose the kernel from PhilZ and install following the recommended method (very easy).
After this all work perfect, I do a full backup of actual system (this is nandroid backup, right?) and after this I install the CM 10.1.3 that also work well. I not rememeber exactly, but following some steps to install this ROM I do before or after install this procedures also: WIPE/DATA FACTORY RESET, WIPE CACHE, WIPE DALVIK CACHE. This procedures are correct?
The device work well, but I have a big doubt because if I boot into recovery I not see anymore the PhilZ touch interface, now I see:
CWM Based Recovery 6.0.3.6
that is other recovery, right? Is normal this behavior? I not understand in what step I change the PhilZ recovery to CWM.
Thanks in advance for all info and help to clear this
This is the CWM recovery same as philz, the difference is that, the version you used before.. It was touch, and after flashing the recovery changes as the CM 10.1 flashed their own kernel...
so it is the same recovery, do not worry
and yes, AOSP/CM roms have their specific kernels, so please do not flash philz on the current recovery...
and one more thing... the process is correct, do a wipe data and factory reset and then format system and preload
Thanks NoteboyTech, yes, I know that work basically like PhilZ, but my main doubt is in what moment of all procedures are installed the CWM Based Recovery. This mean that this CWM are installed in the moment that I install the CM 10.1.3?
Now if I like keep the PhilZ, is safe if I boot again in recovery and install from the .zip file from PhilZ again? or not recommend this?
The wipe: I need made the wipe factory, cache and dalvik before each time that I like restore a ROM or also kernel?
Thanks!!!
You are using a cm rom. Philz kernel Tw doesn't work with cm rom. If you flash philz on cm, phone won't boot.
There is no need to wipe if you just changing the kernel.
If you want the touch recovery, you can install nx kernel which includes philz recovery and is a cm based kernel.

Now I believe that understand a bit more
Perfect. This mean that if I like keep the PhilZ as recovery I need install the nx kernel, right?
Now, if for example in the future I like try one new version or actual version of my stock ROM, is safe to download from Samsung Updates website, install from .zip like I do with the CM, and ready, I have the stock ROM. Is correct?
OK, I not need wipe anything for kernel installations, but yes for ROMs, right?
Only data/factory and cache or also dalvik?
This wipes I need made before install the ROM or after?
Thanks for all!

Can be possible that I detect that after I made all these changes (change the recovery, root, install new rom, etc) the Serial number of the device has changed? I can change from any area to the original one?
Option to backup efs is in the philz recovery. Or you can use ktool from the playstore to backup efs. This has to be done as soon as you root. There is no point of backup if the imei has already changed.

No, the IMEI is correct, the change is in the SERIAL NUMBER of the device, not IMEI. This can be fixed writing the correct serial number?

Well, it so happened that I was on omni rom 4 3.1 with cocore kernel twrp recovery and I saw in a thread that we can theme our recovery by adding a ui.zip file in the theme folder of twrp. Ever since then, my phone boots in recovery only (without the three button combination). Plus in twrp, the theme is applied but I get a super zoomed view of the recovery so I can't restore nandroid as well. Of course, I used my last resort and brought back my phone to stock through odin but the problem is what did I do wrong and what should I take care of to prevent this sort of **** from happening in the future?

Do not mess with something that you are not sure that works on our phone. If you read that someone that has I9070 phone is using something, you can use it. Searching and using stuff from other phones can make you mess like that you got.
Omni MUST use its kernel, you CAN'T use COCORE on it. You will end up with a bootloop if you use COCORE on OMNI.
What you need to do is to flash stock FIRMWARE with ODIN. Download CoCore kernel, UNPACK it and use KERNEL.BIN.MD5 (copy to phone memory). Install UKF and ROOT EXPLORER. Open Universal kernel flasher and follow the procedure to install COCORE. Install, reboot and you have permanent recovery (CWM or TWRP depends what CoCore version you choose).
Perhaps you guys misunderstood me.. I did not flash cocore on Omni.. I flashed cocore on stock and then I flashed omni rom.. so I guess I have permanent recovery..
Im sorry if I sound like a noob but hey, every expert was once a noob, Im learning
I agree to the part of messing with things that people Dont use on our phone, I'll see to that in future..

So if i flash from stock rom jb to cm11 (tc) , the recovery changes to cwm , no matter if u had CoCore+cwm or CoCore+ TWRP in stock rom.
What happens to the kernel in cm11?
i have done nandroid backup with TWRP, but since recovery changes to cwm in cm11 , will i no longer be able to restore the backup ?
Would it be better to do a nandroid backup with CoCore+Cwm then?

If you flash stock JB firmware you get stock recovery (not CWM or TWRP). And you can't use nandroid backup of JB if you are on CM11 because Preload partition is used for SWAP, and it will be non usable for JB. You must flash script to repartition it or flash stock JB firmware. If you have TWRP backup, flash stock JB, root it, install CoCore with TWRP recovery and there you go...

Thank you. So i understand that nandroid backup is useful only when something goes wrong during the process of upgrading from stock JB to CM11 .
one more doubt, I have also backed up app user data + system data with Titanium Backup Pro. That can be used to restore all data after i upgrade to cm11 right? Will Titanium Backup Pro take care of efs ( related to IMEI no.) if something goes wrong after flashing cm11. Btw i have also backed up efs with Samsung Tools app.
Also could you enlighten me about my first question in previous post " what happens to kernel in cm11" ?

CM11 ROM 4.4.2 or 4.4.3 is the result of an update of version 4.1.2 of Android Jelly Bean. If right now, you have a backup system and applications that have been stored in the system when you are Jelly Bean. Then you want to restore the backup to the CM11, then I guess you will get an error. Because the system is Jelly Bean, and Kitkat system is 2 different things in the context of the "system". So you can do this while using TB Pro applications only restore data only, such as: backup contacts, sms / mms, third-party applications such as, apk, application of playstore etc.. Not the whole system ROM previously, JB.
Related to the kernel, system jelly bean, and kitkat system, has different kernel. In this case the kernel is owned by CM11 ROM, not the stock ROM 4.4.2/4.4.3 by samsung. CM11 kernel 4.4.2/4.4.3 allows us to perform GPU OC and CPU OC/UC/OV/UV In the default kernel Stock ROM (JB), you will not be able to do it, unless you replace it with a custom kernel, as the Cocore kernel. Hopefully it can be more clear.
