[Q] Switch kernels. Wipes? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi all.
I'd like to know what should I wipe to safely change from one kernel to the other.
Just flashing kernels, nothing else.
For example if I go from a CF kernel to a stock one.
In that case, will it be possible to wipe from a recovery menu even if I don't have access to CWM anymore?
Thanks a lot.

Kernel script cleaner is good when you changing kernels.

Seems to be for CM7, isn't it?
I don't mean to constantly change kernels so I don't mind wiping through recovery if necessary instead of using some extra app as long as this is the recommended procedure...

Look for lippol94 ultimate kernel cleaning script in the dev section...
There are 2 versions one for CM7 and the other for samsung rom's...
It will be best for changing kernel's

I both use and recommend this as well.

if all you are doing is going from CF kernel to stock a clean is not necessary as the CF kernel is mostly stock but with root added. A more comprehensive clean is only needed if moving back from a more heavily customized kernel or from one custom kernel to another.
A system cleanse also is recommended when moving from a custom rom to another and especially if moving back from a deodexed custom rom to an odexed one and after changing themes.

[Q] kernel flashing for what reason?

Hi,
for what reason do I a kernel flash? Are the rom included kernels better then a lonestanding once? can I flash any kernal to any rom?
what is the benifit of flashing an other kernel then the once ued in the rom?
thanks
When you change the kernel you choose a better kernel then stock.
They are more tweaked and habeas more support fir different things.
**Using my own JPX kernel, z4mod, 345MB Ram and ext2 filesystem**
- Different file system (better battery life) (I'm still experimenting with finding the right one)
- Access to the kernel allows you to use the led backlights on the buttons for notifications.
Those are currently the main reasons why I flash diff kernels.
You can have direct acces to one of the most advance lag fixes around(voodoo) better performance ,overclocking ,color correction for ur display,more user accessable ram and so on

Good question.
Samsung open-sources their released ROMs from time to time and many of the "kernel-hackers" (I'd call them plain hackers, what's with the prefix?) here utilize it to add/provide features and fix bugs (bugs are overlooked by people, its normal).
For instance, SpeedMods' kernel provides an Overclocking support for your Phone's CPU, if you want that extra juice. Likewise, Voodoo provides a set of visual enhancements among other things.
HTH
Another important reason is to regain 2e recovery if you lost it after flashing a stock firmware. This assumes the kernel you choose includes this feature
Fine, thank you all!

[Q] Help me out!! flashing custom ROM

Im currently on a rooted stock ICS (DDLPA) with speedmod kernel k3-3, and im a newbee to flashing a custom rom:fingers-crossed:, just want to know how to flash a custom rom that is safe from bricking in simple steps, and i want to know which rom is best also with some stock holo theme flavors on it?? please members help me out:crying::crying:
What custom rom do you want to install? Read its first page and you should get instruction on how to install it.
PS : consider using the "search" button
First of all, please do flash custom ROM. You lose so much using Samsung's bloated firmware... If you're after Holo Theme, you're after AOSP based ROMs. The best options in my opinion are:
- CM9 if you want fast, clean and smooth rom.
- AOKP if you want rich options etc.
- Paranoid if you'd like to use Tablet/Hybrid UI.
How to flash ? Look any of those ROMs up and follow instructions. Usually what you have to do is:
- Root and install CWM via automated Zergrush script, so it's really a one-click operation.
- Flash a .zip in recovery
- Do a wipe ( if on safe kernel )
- Reboot and enjoy
It's not difficult, simply follow the instructions in ROMs thread, and if you need any help - just ask.
Just use titanium backup to remove unwanted apps. There is a list in the themes section on which apps is safe to remove.
Alba rom is stock and runs fast on speedmod k3-3. Again, you can remove whatever app you wish to.
There is a script on themes section to automatically remove all the bloatware.
Keep on reading.

You can surely flash Rocket Rom V7 from Sepedmod kernel coz its a safe kernel...Boot in Recovery....Do a full wipe (Data,Cache,Dalvik) den flash the RRV7 zip...Nd you're done....You might lose root....So after a reboot flash the attached CWM SuperSU zip without any wipe.....ND REMEMBER NEVER WIPE ON ROCKET ROM WITHOUT FLASHING A SAFE KERNEL AGAIN....coz RRom installs CFRoot kernel which is not that safe....so its better to flash a kernel like franco or speedmod after flashing the rom....nd also before flashing a custom kernel use the jBroid cleaning script attached....just flash it before flashing the kernel....(Press THANKS if helped)

Its written Abyssnote kernel bcoz earlier that was the only custom kernel considered safe....but now with the kernel source code being released Speedmod and Franco Kernels have MMC_CAP_ERASE removed which triggerred the brick bug...therefore its safe to wipe from these kernels....Just follow the steps I mentioned....and if u wanna use abyss kernel (i.e. method b2) then okay....but you are just wasting ur time....Coz speedmod is SAFE....(press THANKS if helped)

I am also on Rocket Rom V7...that's why I can say dat its safe....U can go through the threads of franco nd speedmod kernel...Its written there only that they are safe due to removal of MMC_CAP_ERASE....the only difference in my method nd dat explained in the RR thread is that they are using safe abyssnote kernel nd I have asked to use the speedmod kernel on which u currently are nd which is also safe...I was just giving u a shortcut which is also SAFE...Don't forget to press THANKS

Good to hear that....
:cryingooo,, gotta problem, everything seems fine, but after sometimes my note is freezing and restarting, is it because of the kernel which i use? waiting for your solution:fingers-crossed:
its possible, some users have mixed reviews about franco's kernel, try an alternative like speedmod.
did you do a full wipe before changing roms ?
you cooled me down azzledazzle!! just now flashed speedmod kernel and yet to see any reboots,:good: and one more noob question, apart from custom rom, what else can i do to my note to get the best out of it? some points can be helpfull
what cant you do ??
you can tweak the **** out of it, install a load of init.d scripts, theme it, add a ton of mods. just keep scanning the themes and app section for new mods

[Q] Rooting & flashing CM with brickbug?

Sorry if this gets asked a lot, but I have just checked for the brickbug and I have it. I looked on the wiki but the links are dead except for a couple of guides and I don't know which ones are reliable.
Is there a guide that will help me root and flash CM or PA? I've done similar with a SGS2, so I know what I'm doing, I just don't know which kernels are safe to use or which method to use to not destroy my Note.
Get a root-kernel from http://forum.xda-developers.com/showthread.php?t=1901191
flash it from recovery and you will get root. which kernel to choose is in the thread too.
once this kernel is installed you it will be safer to flash different roms.

Thanks that worked perfectly and simply.
Just have a couple more quick questions: I used to use a LINARO/SABERMOD CM build on my SGS2, is there anything equivalent for the Note?
Also is there anything close to Dorimanx in terms of features? That was a great kernel on SGS2.
I went with CM 10.2 btw.
There is nothing optimised. No best rom or kernel. See what suits you better. Roms like PA and PAC have lots of customizations and kernels like NX has lot of tweaking avaliable.

[Q] recomended kernel for PARANOID ANDROID 3.99?

I'm gong from alliance ROM to PA, and wanted to change the kernel. Not looking to overclock or anything, just a good solid kernel.
Also - what's the safest way to change the ROM?
I'm asking as some kernels aren't safe, and I actually have no idea if the kernel I have is dangerous (alliance ROM comes with it's own kernel).
All I know is how to unroot, and then safely root and install PA, but was wondering if there's a simpler way.
Thanks.
Alliance rom has a safe kernel... PA comes with its on kernel.. good solid.. if you want tweaking, try raw/NX kernles
Personally I'd stick to stock and do my own tweaks, but if you can't do them yourself you can choose between Raw and NX.
Raw is more focused on battery life, while NX makes your phone amazingly fast. Just test both of them and see what works best for you
As for changing your ROM. Just boot to recovery, format system/data/cache (sdcard is optional but I highly recommend) and install your new ROM zip and gapps.

Precautions before installing custom ROMs?

Hi guys, I am new to this Forum.. I wanted to root my GT-N7000. So i searched the forums and i followed the guide of Dr.ketan and used the recommended method ( 1A - Flashing safe kernal with CWM recovery with touch 5 ). Had a bootloop on second restart, ( did reset and rooted the phone using the 1B method flashing SuperSU and Busybox ) Nevertheless successfully rooted my phone.
Now i wanna try Custom ROMs..Is there any precautions to be considered other than Nandroid backup?.. Also i have only a 2GB memory card.. Would it be enough to make Nandroid Backup?..
I also read by Installing Custom ROMs, we will lose Stock apps ( Since apps like S Note need some TW kernal ).. Is there anyway to Port or install or Mod available to install stock apps like SNote and Splanner in Custom ROMs?..
Finally, will the SPen work with Custom ROMs??.. I mean will the Custom ROMs for Note will have the Kernals Inbuilt for SPen or we have to install the Kernals required?..
Thanks a lot for viewing this thread and Thanks in Advance for your replies
PS:- Please excuse me, if the above questions have been asked before, cuz i searched for it and couldn't find it or they were complicated for a noob like me!
For flashing custom roms you will first need a custom kernel with cwm and safe to flash from.
It depends on the ROM you want to flash.
Don't worry about the sd card size, you can make backups to internal sd also.
Custom rom based on touchwiz do come with the apps you mentioned. But if you are going to try AOSP&CM roms them they won't work as they need tw framework.
Kernels not required for spen. Framework. Roms based on Samsung firmware support spen but AOSP&CM roms will not. As a stylus it does work though. Not like popus you get on Samsung roms.

I had already flashed Philz safe kernal with CWM.. So I dont need to flash kernals if the Custom ROMs are based on CWM right?.. and for the Spen to work, i just have to find Custom ROMs based on samsung firmware support? or Custom ROMs based on TW?..
Thanks for your help
If you have flashed philz kernel then you should be good to flash most of the roms except 4.4 as they need newer version of cwm. Eg raw kernel.

Thanks a lot.. I have one more question ( pls bare with me )..
If for eg.. i wanna download this SuperBean v1.5 XXLT6.. The last 5 letters, what exactly are they?.. My mobile Build No ends with:- DDLSC and my Baseband version ends with :- DDLS6...
Does this last 5 letters of Superbean ( XXLT6 ) have anything to do with my Build No or Baseband version?.. When i downloaded the Philz touch 5 CMW recovery with safe kernels i Noticed, he had seperate files for seperate Build Nos..
So do i have to check the Custom ROMs for my Build Nos or is it only for kernels and CMW?..
Thanks for your help
Those are roms build for different regions. You can flash any build number. It's up to the developers on which rom version is his ROM based upon.

One more thing to do before installing a custom rom is to BACKUP YOUR EFS FOLDER.
Or do not do it and your phone could end as a small tablet/big mp3 player.
Unlikely, but i bought one with damaged EFS folder last week to replace my screen. It does happen.
