So I'm still kind of a newb in this flashing thing and since I couldn't find anything using the search box here it go:
I an using Xceed custom kernel and now I want to try another one, but even after I flashed another custom ROM I noticed that Xceed still is my current kernel.
How do I safely change from one custom kernel to another? Do I have to flash stock MIUI again to return to stock kernel or is there an easier way? I ask because the last time I flashed the stock ROM I thought I had bricked the device.
Thanks in advance.
You shouldn't flash a custom kernel over another custom kernel. If you have made a backup of 'boot' in twrp, restore 'boot' only and then flash another kernel. If you haven't made a backup, then your only option is reflashing miui.

Hi, i recently updated to a new custom rom.(from rocket rom gb v23 to rocket rom ics v1)
Unfortunately it looks like installing the new custom rom made me lose my root privileges on the phone.
Is there a quick way to root the phone again?
Do i need to follow the guides to root the stock rom and apply them to the custom rom or is it different?
Thanks
If I were you I would be careful since RR ICS has a Samsung kernel that might have the brick bug..
You're better of using PC Odin and flash one of the prerooted GB ROMs, get CF-Root for it and then flash RR ICS from there again if you would like
The thing is that i was on a cf-rooted gb custom rom before flashing rr ics v1, but on rr thread, in order to install the ics rom from the gb one, they say to first flash abyss kernel 4.2 - full wipe - and the install the ics rom.
I think that's the passage where i lost root, but i may be wrong.
Would restoring a clockworkmod backup with gb custom rom(rr v23) be ok?
One more question, what's the difference between flashing with odin(never used) and flashing from recovery?
Thanks for your reply
Flashing through AbyssKernel should not cause you to loose root, it just sometimes happens :/
I think it would be safer to follow the PC Odin route and flash a prerooted GB ROM, get CWM recovery and then do your flashing/restoring from there
PC Odin communicates directly to the bootloader when flashing, hence it's safer, while CWM uses the current kernel you have so if you're on an affected kernel you're at risk
I'm currently running a custom Gingerbread 2.3.6 with Semaphore JW1 2.40 kernel. I have root, superuser, and CWM, and I want to flash Cyanogenmod 9.1. I didn't get a specific answer in the CM forums, hoping for better luck here:
My questions:
1. The installation guide says to flash back to stock if already running a custom ROM, but what should I flash? Since CM9.1 is a ICS based ROM, do I need to flash a 4.0 ROM?
2. Should I flash the kernel to a stock one as well? I've seen a general guide in the CM forums saying to start from stock and Semaphore gingerbread based kernel, and then just run update.zip from CWM. On the other hand, I've also seen a contradicting thread saying that CM9 is only compatible with ICS kernels and using a GB kernel will cause a bootloop.
2. I also have the filesystem converted to ext4. Do I need to convert it back before doing anything?
3. Does CM9.1 installation come with its own custom kernel? If not, are there specific kernels that can be used with CM9.1 or is any Android 4.0+ kernel usable?
Hey
I think you should revert back. Flash stock gingerbread with odin, install sempahore kernel and flash the rom you want(I would actually recomend cm10, Its very stable). Goodluck!
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?

this is the one you use - PhilZ-cwm6-UBLPC-UUB-2.7
http://www.mediafire.com/file/35d4kd...2.7-signed.zip
the zip file mentioned above can be flashed using stock recovery. Put the file on ext SD card > boot into recovery > apply update from external storage > thats it

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.
Sent from my revived Galaxy Note
Thanks guys for the quick replies, i'm gonna flash the philz kernel now and give the leaked version of JB a try.
make nandroid backup 1st..
Hi there, i am on stock rom 4.3 and i am considering to flash a custom rom. It is going to be my First flash of a custom rom and i am wondering if something is not working as it should, will i be able to return to stock with no problems? If i install a custom Kernel as well will kies install stock firm as usual (to return to stock)? Or the only method is a full backup and restore? Restoring method restores kernel too? Thank you for your help.
U must rooting your device, next install custom recovery and backup your rom, thats all, and next try the first install omni rom
I am already rooted. Omni is one of my thoughts. Should i flash a custom kernel after omni or it is not mandatory?

Tangerine only works for Lollipop roms so don't even try it or you be stuck in a bootloop, Doom kernel I think it's too old, try Williams Kernel 9.1, best one for 4.3 roms. Did you unlock your bootloader?

Flashing a kernel doesn't auto wipe data. Since you're completely stock right now, I am guessing you'll be flashing the kernel via fastboot so you should be fine. As for boot loop errors, the kernel's meant for stock based roms so it shouldn't be a problem. I remember using it with Existenz. Worse case scenario, you'll have to reflash the kernel part from the stock firmware with Flashtool if things go wrong. Alternatively you could take a backup of your kernel via Rashr since you're already rooted.
Speaking of Rashr, you could use it to flash a recovery in your Fota partition which doesn't go away unless and until you remove it using stock firmware. This means that no matter which kernel or rom you flash, you'll always have a working recovery to get yourself out of trouble. You can take a complete nandroid backup of your system before even trying Williams kernel and in the off chance your phone is stuck in a bootloop, you can just restore your nandroid backup and you'll be back to stock.
If you're still worried about your data, just get Titanium backup and make a backup before you proceed. I have switched over a dozen roms in the past few months only because of it. Imagine setting up 30-40 apps every time you migrate to a different rom

If I am not mistaken, SP like most older Xperia phones (not sure about the new ones) does not have a stock recovery nor does it have a recovery partition. The recovery is part of the kernel (the boot.img file or the .elf file). So when you flash a kernel, you are flashing the recovery along with it. This is why people flash a recovery in the Fota kernel partition since its a separate partition and is not overwritten while flashing other roms or kernels. A recovery flashed in the fota partition becomes your primary and only visible recovery irrespective of how many recoveries came bundled with the kernel you flashed. The only way to remove it is by flashing stock firmware or to be more specific, the fota kernel from the stock firmware. If you need it, you can find it here :
http://forum.xda-developers.com/showpost.php?p=59908442
Now since your phone's already unlocked and rooted, go grab Rashr from the playstore and use it to flash the latest Twrp from here :
http://forum.xda-developers.com/showpost.php?p=61698751
This way you will have a permanent recovery which you can use to take a nandroid backup before you try new roms or kernels and restore it if things go wrong.
Your other option is to flash the kernel via fastboot but remember if you flash another rom, the existing kernel will be overwritten by the kernel that came with the rom. It becomes really cumbersome when you are trying different roms. Another reason to flash a recovery in the Fota partition.
As for a new kernel speeding things up, yeah it helps. The first link is also the main thread for Tangerine kernel which has CPU overclocking and governor options and a bunch of other tweaks to improve performance but its only for LP roms. If you wanna stay stock, you can try the Williams kernel. Doesn't have as many features as the Tangerine kernel but more than the stock kernel. If you know which tweaks to make, I am sure you can gain a performance boost from either.
