Custom Kernel Question - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi, if I've rooted my 9305 and installed cwm can I install a custom kernel of a different size or just one thats the same size, also if I have a bad flash with the kernel can I recover from it with the stock or is it bricked thanks in advance. Mark

Hey,
the only kernel you can flash is perseus, see http://forum.xda-developers.com/showthread.php?t=1932997
Make a Backup with cwm, If something went wrong, flash the stock kernel via cwm (advance).or recover the full backup.

ok thanks I'll just asume its because of the size if they're both the same, I guess the bootloader is not unlocked, I saw a thread on google about Adam Outler getting U-boot on a camera with very similar hardware, lets hope some experienced programmers on here will be able to port it to this device, would be great thanks, Mark

[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] stuck plzz help abysskernel !!!!

HI, guys i had perfectly fine working note but some how wanted to flash abysskernel to overclock downloaded and flashed it on ICS stock rom....and crap now m stuck at boot of my galaxy note .....stuck at boot animation of custom logo not going further. i downloaded costom logo abysskernel and flashed it through cw mod.
plz hellp all tech giants and masters here as i dont want to format my phone a lot of stuff is thr...please tell me how to go back to previous state without losing data. i have tried wiping cache and dalvic cache but still stuck at boot....HELP!!!
abyss kernel cannot use with ics since it is a gingerbread kernel. a ics is required to have a ics kernel for it to work. what can you do is if you have a nandroid backup, just restore it using the abyss or if you are running a stock ics, just find a compatible ver of cfroot ics kernel and flash it via abyss.

First of all, if anything goes wrong, this is your safest way to not cause any additional harm to your device: http://forum.xda-developers.com/showpost.php?p=18981227&postcount=4
But since your backup is not working, you don't want to employ this method right now.
So you just follow the advice of janice1234 and find a compatible (with your ICS version) cf-root kernel (v5.6!) here http://forum.xda-developers.com/showpost.php?p=26746339&postcount=7, copy it to your external sd via anything that lets you access it (e.g. adapter or another phone) and flash the kernel with abyss.
While you're in the dev section you could do some more reading, for example all the information chainfire provides in his cf-root kernel thread...

hi got all u told me just one more thing how to flash wia abyss.....dont know how to ...i know how to flash via cw recovery touch i have it but from theer cf root have .tar file and it cannot be flashed through cw recovery so how to flash cf root from recovery. thas all i need to know.
thanx
You need to download a rom that can be flashed through cwm / abyss red. Try criskelo v7 ics. Download to your pc, copy it to your SD card using SD card reader) then reboot into recovery and flash it. If you have stock ics, I would do the 3 wipes first before flashing the new rom. Make sure you are doing all of this from abyss 4.2 cwm and not ics cwm.

Usually people run into this problem the other way around.
Anyway, once you have downloaded the .zip file there is no need to unzip it, since the .zip is exactly what you need to flash in CWM as it can't handle the bare .tar.

[Q] Galaxy Note ROM Flash+CWM.zip root (confusion)

Hello,
I want to flash the Chimera 3.0 Rom to my Galaxy Note. Well, I already looked for many tutorials that couldn't help me.
I rooted it by using a youtube tutorial which I can't find anymore at the moment. But I remember downloading 3 files: cwm.zip, franco kernel and another zip file.
So, I read that if I flash a new rom with the cwm.zip installed, my phone will get bricked (which I obviously dont want to happen).
The more i read the less i understand Now i really dont know what to do...
At the moment, the original ICS 4.0.4 firmware is installed, and i didnt make any changes to the kernel (or maybe that franco thing did, im not sure).
Also, I didnt understand what to do first: flash new kernel or the rom? Because the kernel needs to be safe so that my phone doesnt get bricked.
Anyway thanks in advance!
P.s. sorry for my english, i'm german
You always need to be sure your ROM is running a safe kernel. The standard kernels from Samsung are NOT safe, i.e., if you do a full wipe/reset to factory settings, you can get your phone bricked. So, before doing that, you need to flash a kernel that works for your ROM and is safe. If you are using a Samsung ICS 4.0.4 ROM, I would suggest Speedmod K3-15 or Hydracore 5.4 kernels. Since you already have CWM installed, it's rather easy: download the kernel zip file to your SD card, reboot your phone in recovery mode (to access the CWM menu), select "Install Zip from SD card" and flash the kernel. Don't do any wipes, just reboot. Now you got yourself running a safe kernel. Confirm that by going into Settings -> About phone.
Spend some time reading the tutorials here on the forum. Trying new ROMs is nice, but bricking your phone is definitely NOT nice, right? So, make sure you understand the whole process and can make sure you are on a safe kernel before proceeding.

Stop using obscure tutorials - use XDA.
There are many threads here providing detailed and exact information.
Until now you should feel very lucky that you didn't brick your device.
Choose an up-to-date Rom here and follow the installation instructions provided in the thread - I do not know any Rom thread that doesn't give this hints.
cwm.zip, franco kernel and another zip file - after you told about the first two I do not really want to know the content of "another zip file". Delete them - they are old or dangerous.
Download some nice JB Rom here or switch to CM 10.1. You will like it and learn.
(You shouldn't be concerned about your language knowledge - it is far better than your device knowledge )
Ok, i installed the hydracore 7 kernel. what exactly am i supposed to do now?
so you on ICS and have hydracore kernel installed now ?
if yes, then place all the required files to install the rom on internal SD ( check OP rom thread for details)
boot into recovery and go to mounts & storage > format/system > format/data > format/cache. go to advanced and wipe dalvik cache.
go back and choose install zip from SD and select the ROM file
This worked for me, thanks!
Hi,
I'm currently running on ICS 4.0.4 stock ROM, I was wondering how to root and add CWM?
need much more info than that. which build of rom. use the philz kernel for your rom to root and CWM. follow his thread

[Q] Read alot, can someone please confirm I am doing this right.|RESOLVED|

Hi guys I'm new to the N7000 forums, but I am no means new to the android and flashing scene. I'm just a bit confused as to how to safely install ROM's on the note.
I've attached a screenshot of my "about phone" so you guys can tell me what kernel I should flash before installing different ROMs
The ROM(s) I'm interested in flashing are Jellybam, Sweet ROM (JB version) and Ultimate jellybean. Can these roms work with any safe kernel? i.e. once iv'e flashed philz or franco kernel I can let the flashing begin.
Also do I need to flash a safe kernel in order to install cyanogenmod or other, not based on stock roms?
Forgot to mention that I am rooted. Any help at all would be appreciated, if I am wrong about anything so far, feel free to set me straight.
Thanks to all who responded, if anyone else wants to reply feel free but i'm going to mark this as resolved so their won't be any confusion.

if you are on stock kernel then download Philz kernel for LP7, flash that in recovery, should give you root again aswell. then you can flash away to any of the ROMs you listed above. just every time you flash a ROM or think of factory reset or data wiping make SURE you're on a SAFE kernel. that's all
as you are rooted, just install any safe kernel like hydracore or philz. thats all. then you can try out any rom. Just make sure you follow the instruction to flash the rom in the OP
I saw that the Philz kernel has a lot of different versions, which one do I choose, am I right in saying the UBLPC one, as that is my build number? Or any one can work, I also read that you should not flash with the temp CWM, I will admit though I used the temp CWM to flash the root files and i'm still ok but I don't want to take any chances, how do I flash with the stock recovery?

First, forget about the franco kernel. The franco kernel for the Note is outdated and thus useless. Second, if you plan to flash a JB leak the only kernel you should use is PhilZ. And especially important with the JB leaks is to stick exactly to the instructions how to flash. Otherwise your phone won't even boot.
Have fun with your device! The Note is still an outstanding phone.

Thanks guys for the quick replies, i'm gonna flash the philz kernel now and give the leaked version of JB a try.

Is Galaxy S advance supported with Rom Manager? If Not, other ways to change ROMs?

Hello,
I have recently purchased a Galaxy S Advance phone, and I am quite new to the android os.
I have read already many guides and forums about the whole process of rooting / flashing etc, so I have some knowledge of the terminology.
I already have a rooted phone with GB on it (yes, I know JB is about to come out officially ) and I wanted to change some of the UI elements.
I installed the rom manager app by koush, but yet to use it because I saw that in the past that the phone wasn't supported.
My question is: Does ROM Manager support this phone? Can I go ahead and flash CWM on it from the rom manager app, and then use it to flash other roms?
If not, which is the best solution to backup and replace roms? ODIN?
Thanks,

Other way to change roms is custom recovery. On GB TWRP, on JB CWM.

I think it is not working. It is not supported. Way we install custom ROMs: download ROM zip, transfer to SD, then go to recovery and install it from there.
I checked TWRP supported devices list (tried to link it but forum wont allow new users to link ) and I don't see the galaxy advance S on their list either.
Is there a special mod version for this device?
And another question, if installed, will this wipe the current phone data or just the recovery loader? Since I want to backup my current ROM (+ contacts, settings etc.) before doing anything sketchy...

You have GB? Look here.
On I9070 recovery is on the same partition as kernel. So it can't be installed separatly. It is ported. You need to install this kernel, or CoCore. If you install with Odin - you will increase binary counter. For installation with ADB shell, or Terminal emulator (app from market) you need root - and it will not increase bc.
So I am guessing I will use the dd command line way since it doesn't increase the binary counter (why would we want to do that ).
Is it possible to backup the current ROM before flashing it with the TWRP modified ROM?
And another thing, since I will be using other ROMs, how can i add the TWRP recovery loader to them (you said that the recovery is on the same partition as the kernel, making me believe that each ROM I load will need to have TWRP on it)?

No, only JetMOD have embendend kernel too. And it have TWRP.
Hm, another thing. You better use non binary counter increaing root method. But it need you to flash whole firmware with Odin. And maybe you loose data. But if you do not do factory reset - it will be ok.
Sorry, I didn't understand your last post.

If you want to get TWRP with dd command you need to root your phone first.
There are 2 root methods. One that increase binary counter, and one that do not..
With one that do not increase - you need to flash whole firmware with Odin. And by doing that you might need to do factory reset. That will cause your data and app delete. You can try to boot, maybe it will be ok.
Oh, I already said I have a rooted device, so this wont be an issue.
What I asked was:
1) If I can backup my current ROM before installing the TWRP ROM you linked (in case something goes wrong).
2) When I install other modified ROMs, will they override the TWRP I installed, or just change the kernel system leaving TWRP in the recovery?

Didn't pay attention.
You have backup option in TWRP, and you can restore it.
Custom roms do not have connection with kernel, just JetMod who do have kernel with TWRP too.
P.S. lol you confuse me. TWRP is kernel related, nothing to do with ROM.
When you want stock kernel back, just flash your firmware from sammobile.com.
So you need to change kernel to get TWRP. And with TWRP you do backup of system.

Hmmmm, now I am a little confused.
Since I don't want to touch the kernel (yet), all I want to do is change the ROM (as in UI changes etc...).
I wanted to backup my current ROM and then load other ROMS.
I started off with ROM Manager because it seemed to answer what I wanted to do, but as you said ROM Manager doesn't support this phone and we went from there to TWRP.
Since I now get that TWRP is kernel related only and not ROM management, what would you advise right now for:
1) Backing up the current ROM
2) Loading other ROMs to the device?

You can do that only with TWRP.
And did you read ROM manager description?
* Flash your recovery to the latest and greatest ClockworkMod recovery.
Click to expand...

For ROM manager you need custom recovery. And for I9070 that is embended in kernel. Full stop.
And it is connected to CWM, not to TWRP. We do not have CWM for Android 2.3.6. ported.
P.S. So to close this:
- You can't do any backup, installation of ROMs without custom recovery (in our case TWRP) on our phone.
- Custom recovery couldn't be installed separatly - it is embended inside kernel file - and has nothing to do with ROM.
It is clear now?
I think I got you now
1) CWM doesn't work on my phone because the recovery is attached to the kernel.
2) In order for me to backup my ROM I need to install the kernel with TWRP embedded (the one you linked me).
3) I also can't backup my current kernel without TWRP so in order for me to have TWRP I will be doing #2 without any backup? I am guessing this is the part where bricking has a chance of occurrence?

CWM = TWRP
Both are custom recoveryes. Not the same, but same purpose.
1) Our phone have same partition for kernel and recovery. So we can't install it separatly
2) You can backup kernel, but you will need Terminal emulator, and similiar command like instalation of other kernel
Code:
$ su
# dd if=/dev/block/mmcblk0p15 of=/sdcard/boot.bin
# reboot
This will backup your stock kernel on your sdcard. You can install it later this way (ofcourse if boot.bin file is on your sd)
Code:
$ su
# dd if=/sdcard/boot.bin of=/dev/block/mmcblk0p15
# reboot
You always can flash your stock kernel, Download mode do not have anything to do with kernel and recovery partition.
If this is little hard for you, just install custom kernel with TWRP. Or do not do anything. :laugh:
P.S. Trust me, you can't hard brick device with installing kernel. I am tester, and I flashed at least 10 non booting kernels, and 50+ booting ones.
I do trust you, just trying to get an understanding of how the things work on these devices.
So I now understand the backing up and flashing commands (I would like to know how you knew the mmcblk0p15 was the kernel partition for this phone), so where does the "Download mode" come in handy if u can flash directly from a terminal window?
If for some reason the flash wasn't successful, can you enter download mode and restore the backup you created?

Most likely you will have to flash whole firmware if something goes wrong. I told you what I know.
And if you can go in TWRP recovery, it can restore krenel with other things you backed up. And you can flash new kernel in TWRP too.
Somewhere is written what partition is for what. I do not know that. And developers told us what partition is for kernel and recovery.
I do not think that that thing with restoring downlaod mode will work. Newer tried or heard of it.
I tried to explain you, but maybe I was little confusing. :angel: My english is not great, and I didn't provide 1, 2, 3... steps explanation. Like I throw everything to you. :laugh::laugh::laugh:
:laugh: More or less I understand you :laugh:
So to sum up:
1) Create a backup of the current kernel
2) Flash Stock Kernel + TWRP
if all goes well....
3) Create full phone phone backup from TWRP
4) flash custom ROMs (or kernels) with TWRP
Hows that?

That is ok.
And you backup old kernel that you can easy go back to stock one. Without flashing whole firmware, when you want stock. Like you want to go to service for warranty or something like that...
