[Q] How to do a Nandroid backup on a stock (but rooted) kernel?

Hi there
I am currently on a newly installed JVU that was pre-rooted by [Ramad], so I am actually on a stock kernel. I intend to keep it this way without any custom kernel or rom.
Now I would like to make a Nandroid backup of my phone but I can't do it with my default recovery menu that is without CWM.
Question is, is there any way for me to install CWM on top of the stock kernel so that I can do a backup from recovery? I do not wish to install a custom kernel just for access to CWM. Or is there an app that I can use to simply do a Nandroid backup without needing CWM at all?
PS: I tried using ROM Manager to do a Nandroid, but it would simply reboot my phone to recovery.

Anyone please?

It's my understanding that you need to flash a kernel that has CWM built into it.
CF-Root and Semaphore are the most common ones for this.

did you try the CWM Recovery App, couldn't remember where it is on xda but a search would help

Fairly new to all of this myself but I'm not really sure you need to do a Nandroid back up if you don't plan to run anything other than the stock ROM & kernel.
This type of backup is really for those installing custom roms & kernels etc.
It is my understanding that to run CWM you needed to be rooted (could be wrong). CF-Root is basically a rooted stock kernel so if you wish to do a Nandroid back flash CF-Root that way you can have CWM.
If you are rooted you can use Rom Manager to install CWM. Then boot into recovery (power button, volume up & home button) and do everything within CWM.
Hope that helps.

Hi
I do know the popular ones but I wish to remain at stock as I will be passing the phone to my mum soon.

Actually I am already rooted but I am on a stock kernel without CWM. As for Rom Manager, I have mentioned that it doesn't work. Seems like it requires a CWM enabled kernel for it to work.
I want to do a Nandroid backup now as I will be handing over my phone to my mum in afew months time. And I am pretty sure I'll make changes to the phone in the meantime. So I would like to have a Nandroid that I can restore to before I pass it over.
As for CF-root, I'll check it out. Thanks for the suggestion.

Same problem here- rooted with stock, and won't go on installing a new ROM before being able to save nand backup...
I think the problem of ROM manager not installing recovery is related to stock recovery version that needs downgrading from 3e to 2e- I reckon to have seen some thread about it here.

[Q] Question about Flashing ICS

I want to Flash Team ICSSGS [Android 4.0.3] (Link to ROM Thread) but I am not for sure what Bootloaders or Kernel I need to use.
I currently have:
Firmware Version: 2.2
Baseband Version: I897UCKB1
Kernel Version: 2.6.32.9
Build Number: FROYO.UCKB1

In general, the Gingerbread bootloaders are preferred with any of the ICS ROMs, because they are more ubiquitous and can be used with virtually any version 2.1 thru 4.0. Kernel-wise, the ICS ROMs come with a kernel, and your only other option is Glitch v14 beta right now...but mostly, you shouldn't need to worry about flashing anything beyond what's in the ROM itself right now.

So that ROM I listed in my OP comes with its own Kernel?
And is there a particular Bootloader I should use?
If there is, may you please link me to it?

Hey im currently running the ROM you are asking about. To answer your questions you have to be on the gingerbread bootloaders. You can flash those using odin, or since there is an official update out, use Kies mini to update your phone to gingerbread and that will flash the bootloaders for you.
About the kernel, the ROM you posted includes a kernel in the .zip and when you install the .zip it will flash the kernel for you. Its a fine kernel and works great so dont worry about changing it unless you have problems.
Here is the link on how to flash the bootloaders using Odin. Its not a hard process and pretty safe so let us know how you come out on the other side!

Now when I flash this bootloader you listed, will Froyo still boot or will I have to flash my ROM afterwards?

froyo will still boot. GB BL are backwards compatible and the ISCSGS script should allow it to flash over any ROM

Hi all.
as i can't post yet in a thread mentioned by mrnapolean1 (http://forum.xda-developers.com/showthread.php?t=1362092) I'll try to ask my question here, as it related to a question asked by this thread starter
so i have gingerbread 2.3.5, installed CornKernel_UCKK4_v603 and custom rom SimplyStock KK4 V1.0 , so if i wanted to switch Team ICSSGS [Android 4.0.3] should i do following?
1. wipe data /factory reset
2.wipe system
3.flash from recovery mode Android 4.0.3 zip?
I already have a backup made with Efs Pro as a tar file
anything else i need to do?
thank you so much in advance

Yes, Froyo will still boot. If this were a layer cake it would go something like bootloader, kernel, rom. So basically, your bootloader has nothing to do with your kernel or your rom but it is at the bottom layer of the boot process. It does effect which ROMs you can use though as gingerbread and ICS roms require GB bootloaders. So flash the bootloaders, you will still be on Froyo. Update to GB. Root GB. Place the ROM on your internal SD and then flash it. If you run into any problems check the common problems page found on the first page of the SGSICS ROM.

First, if you want to keep any of your apps or contacts backup those as well using Titanium Backup. Make sure to backup to the External SD card or make a copy of the backup somewhere other than the phones internal SD.
Second, you dont have to wipe data/factory reset before you flash. This is only if you have the problem of a bootloop when you try to install. I had this problem and when I did the wipe data afterward it fixed it immediately. So follow this:
1: Boot into CWM
2: install rom
IF you have an issue with a boot loop at this point
1: Get back into CWM using the button combination
2: Wipe data/Factory Rest and Wipe Cach

thank you !
one more question, i understood about data/factory/cash, but dont i need to format system before flashing new rom? i thought its always better to do before new rom flashing?

I think this was true when flashing older roms. When I flashed that ROM I did not format system and it worked fine. Let me know if you have any problems when you flash.

and it is stucked. so may i pull the battery off and go to recovery mode again and go back to my previous room? should i perform system format in this case?

Try to reboot. If it won't reboot then ask around in the icssgs Q and A thread.

do you know safe way how do i go back to SimplyStock KK4 V1.0? should i first flash CornKernel_UCKK4_v603 with odin? but is it safe to do over android 4.0.3?
sorry for bothering you, but i am kind of stucked

ok, in the end managed to boot the phone with working wifi but still would like to know how to flash back to SimplyStock KK4 V1.0, just in case ;-) if that won't be problem for you. thank you !!!

IMHO the best way to go from gingerbread to ics 4.0 is to
- in the development section download stock kk4 without bootloaders, unless you dont have them http://forum.xda-developers.com/showthread.php?t=1300843
- then download a kernel of your choice probably cornkernal and put it on your internal sd card
- download ICS latest build and gapps and put them on your internal sd
- oneclick odin the stock kk4, let it boot up completely
- power off and install kernal via odin without aut reset
- boot into recovery, factory/data reset, clean cache, clear dalvik, install latest ics, then install gapps right after,
- reboot system and youre done.
IF you want to go back to your other rom the simplest way is to just kk4 fresh install, install kernal via odin, then isntall your rom.
I always keep all my contacts synced with gmail, and titanium backup any game data or app data i need, and reinstall apps through the market.
hope this helps

I gone ahead and flashed ICS onto my phone. It is working good but the Hang up button does not work. In order to hang up, i have to lock it and unlock it.
Now i did a Backup of Froyo from within CWM. if I do have a problem, can i go to DWM and restore the backed up Froyo?

(Solved) Problems to get full root on ICS

Hey.
Yesterday i was trying to do an update of the 'SU binary' in Superuser under the ICS StuNNeR v1.4.26.1 ROM. But it didn't let me do it.
It told me something about S-ON and about not having a root access. So i thought that i was kinda screwed.
So i downgraded to an Android 2.3.6 Gingerbread ROM via PC Odin that was pre-rooted to see if that would help and installed CF-Root v5.3 via the 'Initial CF Root Flasher'.
After i had installed that Android 2.3.6 ROM, i made sure that i actually had full root access by copying a file from my SD card to the system folder after pressing the R/W button in Root Explorer.
That went all fine. I could also delete that file in the system folder again. So all was fine here.
Now i went into CWM and did those things.
1. Wipe Dalvik Cache
2. Wipe Cache Partition
2. Format Data / Factory Reset
After that i installed ICS StuNNeR v1.4.26.1 via CWM again (i have tried with other ICS ROMs to).
The installation of the ROM went all fine.
Now i'm in the ICS StuNNeR ROM on my Galaxy Note and i'm trying to update the 'SU binary' in Superuser.
Here it will fail and give me this message: This updater cannot update the su binary on phones that have some kind of write protection on the system partition like S-ON. You can continue to use Superuser with your outdated binary, or update su with ROM Manager.
And when i try to press the R/W button in Root Explorer here, then nothing happens either.
So my question is, what i'am doing wrong here to not get full root?
I have tried every possible ways to get root on any ICS ROMs, but without any luck.
If someone can give me an EXACT way of getting the full root back on ICS, then i would be gladly.

Did you flash the ICS repack?

Well, I was double checking the instructions on Stunner and he doesn't say you have to flash the repack anymore coming from Gingerbread. He said tested and worked fine with CF root. Is the instructions of the OP of Stunner what you did?
---------- Post added at 11:15 AM ---------- Previous post was at 11:13 AM ----------
I know on .19 of Stunner neobuddy switched to SuperSU, but he switched back to Superuser for compatibility with kernel. I'm on .19 now so I can't check the SU binary updater to see if I have any problems or not. Maybe someone else can!

Yes.
This is what i did.
Backup data apps.
Download and copy latest Stunner ROM on your SD Card.
Make sure you are on Rooted ROM. Reboot in recovery.
ONLY IF YOU ARE ON GINGERBREAD: Flash Abyss Kernel. Goto Advanced and Reboot Recovery. Tested and confirmed working on CF-Root Kernel.
Wipe Data (Recommended but not mandatory if you on Stunner ROM already)
Flash ROM.
Flash suitable Modem (Optional, recommended ICS LP5 modem)(not included in ROM)
Reboot and Read Caution.
Do not restore system apps or system data.
So yeah, as you guess. I have no freaking clue on why i can't get full root on ICS StuNNeR ROM (or other ICS ROMs).

Just follow chasmodo's guide in the Development forum (it's a sticky so you'll easily find it)..
Your problem is when you flashed Stunner directly from CWM recovery..
That guide has all the necessary steps, just follow it exactly and you'll be good with full root

So, you can't put a file in /system on Stunner at all? What about TI Backup? Do you use it? Can it gain root access?
I'm trying to work through this with you as much as I can, I'm not the smartest person on here by any means .
I want to tell you to install SuperSU, but I'm not sure if that's best. I tell you what, could you flash .19 Stunner instead of .26.1 and see if it works with root?
Edit:
I'm glad matius44 is on here to help you now!

Are you sure you used Abyss kernel version 4.2 exactly? It has worked for many users but there are minority who did not work for them too..
However, if you want to flash Stunner you can flash the ICS Repack by Chainfire (LP1 ONLY, NOT LP5) and from that you can flash Stunner and maintain root..But it's been discovered recently that repacks kernels are dangerous so I do not advice you to do it, you flash it on your own risk..

I used the AbyssNote kernel 4.2 Final CW Touch one though.
EDIT: Oh, i actually did flash an Android 2.3.6 LC1 ROM that is rooted before i flashed an ICS ROM with the AbyssNote v4.2 kernel. Maybe that's the problem?

Installed a rooted Android 2.3.6 ROM via PC Odin.
Then i used the 'Initial CF Root Flasher' after placing the CF-Root v5.3 (LC1) zImage file in the 'zImage' folder and then used the 'already-rooted.bat' file to get the CF-Root 5.3.
Now i used CWM Recovery (By pressing Volume Up + Home and Power button) to flash the CheckROM NoteHD v6 (LC1) ROM. Yes, i did check that i had full root access here before i did continue.
Now when i'm in the CheckROM NoteHD ROM, then i opened the CWM application and then booted into CWM Recovery and then flashed the 'AbyssNote Kernel v4.2 Red Touch Original Logo'.
Then i restarted the CWM Recovery.
From here i did this.
Wipe Dalvik Cache, Wipe Cache Partition and Format Data / Factory Reset.
Now i installed the Nandroid backup i had of my ICS StuNNeR ROM earlier before i got those problems.
And after i did this, then i finally could update the 'SU binary' in the SuperSU application and get full access to the System folder with Root Explorer .

Am afraid to say you're one of the unlucky few who this method does not apply to them
Now you have 3 solutions:
1- From a rooted Gingerbread ROM flash the LP1 (notice LP1 ONLY, NOT LP5) using Odin (Mobile or PC), and after that flash Stunner from recovery. However, I do not recommend this seeing the recent news of how dangerous ICS kernels are..
2- From a rooted Gingerbread ROM flash the new official CM9 (taking into consideration the known issues) since it uses an open source kernel instead of one of the leaks' kernel
3- Wait for official ICS release so we have more reliable ICS custom kernels
Your choice mate

[Q] GGGRrrrrr no CWM on 4.0.4

UK Samsung Note GT N7000 just upgrade to 4.0.4 N7000XXLRK... everything went fine, found the speed has increased and the battery life is way better than the original rom....
But there is the problem... I made a total backup using CWM before I flashed, but now I'm in 4.0.4 I cant install Titanium Backup nor CWM. to retreave the backup info.. I installed Rom Manager and try to install clockwork through that it download and installed, but nothing else happens,found out Samsung note not supported...... I really need to get CWM installed I have searched the net but very little is coming forward..
The more advanced were getting the further back were going, I may have no chance but to go back to Gingerbread
Thank you for any help you may give.
Merry Christmas & happy New Year. :laugh:

Well it seems to me that you flashed a rom without Root / custom kernel...
The only way in my eyes is to flash a Kernel with CWM via Odin.
Find a fitting kernel here: http://forum.xda-developers.com/showthread.php?t=1789397

thank trahzebuck for the quick reply.. My phone was rooted before, and after the new flash its still rooted, I have just been told to check out "emmc bug" program from play store.. it seem that I have a dodgy chip... I have root checker basic that say I have root access, So its not that I installed a rom without this is what i installed N7000XXLRK_N7000XXLRK_N7000ORALP2_HOME.tar.md5... after reading a little about the EMMC BUG im not so sure I want it now, shame....

Literally just flash it in recovery as you would anything else.
And I'm 99.99% sure you can also just flash rocket ROM in that version of twrp if you are taking about the JB version of alliance.
Just make sure to follow the same wiping procedures
But if you're worried about the emmc brick bug then simply flash philz in twrp and reboot into recovery then do the proper wipes and then flash rocket Rom
Let me know if u need more help.

thanks androidslave, twrp froze the first time i tried flashing cwm , so i kinda got scared. but its all good now
i've got another question
ive been using this phone for almost 2 years now and because of the brickbug workaround the internal sd card hasnt been formatted since gingerbread. so how do i remove all the unwanted stuff from previous roms and apps that must have clogged up??

So long as you're on a truly safe kernel, then you can do it on the phone.
Personally however I wouldnt and never have. I use root explorer and manually delete things I no longer nerd (you can use es file explorer as a safe alternative)
