Hi,
I recently downloaded and flashed the CF Root Kernel v2.9.
I'm running an Android 2.3.3 ROM (Lite'ning rom v4.2).
Now I have been hearing things about how the Lagfix on the CF Root kernel is potentially dangerous. Apparently it corrupts your system when you disable it and switch to another kernel.
I am wondering how true all of this info is and if there would be any danger in flashing to another Kernel/an update of the CF Root kernel.
Any help would be appreciated,
Hobo
PS: Had to post here as I need 10 or more posts to get access to the Development forums...
Me too...I already have 6 post ...now 7
About the lagfix..why you need it for Android 2.3.3??? I think this version already running on Ext4 or I am wrong???

1. where did you hear that the CF Root kernel is dangerous? Links please
2. apart from the fact that the stock kernel from gingerbread has already ext4 support means all hacked kernels should have it too, and also apart from the fact that CF has a nice tool to convert back easily.
If you are already on a custom kernel and you wanna experiment more, you do know you can backup right?
hmm, am interested on what you mean with the breaking system? you mean fs? or it breaks something else?

1) I heard it on a forum for Dutch Android users, Androidworld. More specifically on the Lite'ning rom topic, I can't post a link (see edit) but since all posts are in Dutch I'm not sure it would be helpful for you.
2) Yes I know I can back up, I have everything backed up. Just a bit worried about my phone not working for pre-longed periods or having to go to a Samsung repair point.
3) From what I gather the problem is that when you convert to Ext4 (or convert back) it doesn't completely overwrite the /system/ which makes it so that if you decide to switch to another Kernel it becomes impossible to activate the lagfix and you might get the warning your system is corrupt.
Most of the posts link to an old topic of Supercurio and Voodoo about lagfix corruption (can't find the link right now...)
The problem seems to be solved after reflashing a new ROM with repartition.
/edit: "To prevent spam to the forums, ALL new users are not permitted to post outside links in their messages. After approximately eight posts, you will be able to post outside links. Thanks for understanding!"
So the link isn't a hyperlink.
Well I kinda wouldnt call it a lagfix now. I mean its a switch to another fs.
And I think you got the fixing part about reflashing right. So if you have a backup (also go with titanium on this one) . If you reflash you get your system back in a jiffy. I mean its like 30 mins reflash and initial setup right? And then 15 mins to get the backup online (just to scare you a little and to save my ass from being kicked, if something goes wrong somewhere along the line you have been warned that this can do something bad to your system in a 0.1 percent chance)
Anyway first thing you can do is to reflash to the version 3 of CF
Which kernel are you interested flashing to? (oh and one thing if your rom came preinstalled with busy box and you didnt unistall it and flashed CF on top of it, you can have some trouble)
I thought Lagfix pretty much ment that... Shows how much I know about all of the terms
I was probably going to go back to the Hacked Supercurio kernel.
I am not sure if the ROM came pre-installed with busybox but I assume it was since it was auto-rooted.
Didn't really want to go flashing as I'm always scared of bricking but here I go!
Thanks for the help

Was planning on flashing back to a 2.2.1 ROM with repartition, then flashing back to the original ROM which comes with Supercurio's Voodoo kernel.
(and thanks )
Btw with that term lagfix you were right. All call it that . Just for example nexus S has ext4 as a stock fs. So thats why I said in the future it could be just called converting the fs. Also the rfs isnt so lag plagued in the late 2.2.1 and for sure not in 2.3.3 versions. Thats why no lagfix.
One thing though when you say original rom wiht supercurio kernel what you mean with that?
Oh and have you tried JVK?
For some reason the ext conversion did a lot for me.
Mostly in start up speed after sim-card unlocking.
With the original rom I refer to the un-updated custom ROM I was running when I flashed the CF-kernel.
Haven't tried the unmodified JVK but the ROM is based on JVK
this happens time to time to me. see. I forget what the thread was about. not the first time I posted something in a thread that wasnt related to something completely else
Anyway what were we speaking about?
Ah supercurio, you like voodoo I guess. thats why that. anyway I am running on CF3 on stock JVK with the ext4 fix and i am happy with that.
Doesn't the CWM v3.something have a lot of trouble flashing zip packages?
Because a lot of people haven't updated their update packages?
Not trouble, problem is you need CWM3 update zips. And there arent many out there. And they have to be compatible with the rom you are running too. And CWM3 + JVK is relatively new.
I think I'll remain with Supercurio for the time being then
Atleast until CWM3.0 becomes readily availlable.
Thanks again!

Hello people !
Since I'm living in Tokyo, I'm the happy owner of a Galaxy S, but unfortunately it doesn't seem to be exactly the same like the other devices.
Anyway, since 2 days ago, I had some fun (and cold sweat also) trying to root it, unbloat it, etc... Some difficulties and questions left without answers, so if anyone has a guess, please be my guest !
My phone as I got it :
SC-02B, with OMJJ1 firmware (Froyo 2.2)
1) Rooting
The easiest thing ever.
The SuperOneClick pack did a wonderful job.
http://forum.xda-developers.com/showthread.php?t=803682
2) Getting a "safe" firmware
Just in case anything would go wrong, I wanted to be able to flash back to an official firmware.
The ones from this post work without any problem so far.
http://forum.xda-developers.com/showpost.php?p=10558974&postcount=134
However, problem 1 : I couldn't get Heimdall flash my device. Since I'm mainly working on Linux and OSX, that would have been of a great help.
But the "handshaking with Loke" step is always failing...
Actually, I even though I had bricked the phone, since I was stucked with a black screen (1PC and 1GSM in orange) and it took me ages to figure out how to get rid of that.
Solution : get myself a Win 7 computer at office and use Odin. No problem so far with this one.
Problem 2 :after flashing with the official update, I get complains in the recovery mode (when unpacking the apps I think), saying that /dev/block/mmcblk0p3 cannot be mounted, because it does not exist.
After searching on japanese sites, it seems that there is a 3rd partition in addition to the one for /sdcard and /data that is used (as far as I know, only for that) by an app called DioDict (japanese / english dictionary).
Not that this is a great loss, but I don't know where and why this 3rd partition was deleted. I tried to restore one, but after a while I just gave up, since I don't have any dump of the data that was there anyway...
Could anybody confirm/infirm this ???
3) Recovery 2e
Since I wanted to test to other roms, I needed to get back to the recovery 2e.
I gave a try to CF-root, which included that also.
http://forum.xda-developers.com/showthread.php?t=788108
Once again, Odin was the only one that could do the job, Heimdall still ignores me.
Problem : the update is successfully done, but for a reason I ignore, I lose my SIM card in the process.
Flashing back an official ROM makes it available again, but CF-root won't allow me to phone in Japan.
How did you people handle that ? Unfortunately I couldn't afford staying too long without a working phone, so I didn't investigate much further, but did other people have the same kind of problem ?
Conclusion :
As of now, I have a rooted device, and am pretty happy with it.
However, I wish I could give a try to the nice work I've seen around (CyanogenMod on Galaxy S seemed very yummy), while still being able to use my SIM card here.
Any feedback is welcome !
I haven't played around that much with DioDict to tell you right away how to solve this, but maybe there's some answer getting the first firmware:
SC02BOMJJ1 (10/10/13) :
http://fus.samsungmobile.com/Phone_...2BDCMJJ1_SC02BOMJJ1_SC02BOMJJ1_OM_DCM.zip.enc
BINARY_ENCRYPT_STRING 1662317
thanks a lot for this link ! just a question, where did you guys find them ??? the site itself seems very dummy
but as far as I could read on japanese threads, that seems to be some prefab settings
in my case, that third partition has been deleted, so I think I would have to recreate again beforehand.
as for the "how", I must confess I don't know... I' had somehow succeeded in running parted to create one, but for a reason I ignore couldn't assign it to the block
I could install a Cyanogen Beta3 today, and though everything is alright, still got no 3G.
SIM card is not recognized, and it seems impossible to input the appropriate APN information. Could it be that the modem embedded in the SC-02B is different from the mainstream one ?
EDIT : seems that indeed the SC-02B has a different modem. At least the firmware has a different size, hence the need of a different PIT file when you flash from an "international" ROM.
I'm starting to wonder whether I'll see the end of it someday >_<
things that seem to work
Now that we have the capability to recover after we trash our ROM what can we do.
Super Oneclick root - works
Z4Mod "because we all have the need for speed" -works after you use titanium backup to remove some of the bloat-ware from /system
Z4Control works if you use Z4Mod to patch the kernel and convert /data to ext2 first.
The UOTKitchen will work to change the battery icon and other status bar icons if after you have completed these steps http://forum.xda-developers.com/showpost.php?p=9318973&postcount=1290 you extract the framework-res.apk from the resulting zip file and use adb to push the new framework-res.apk to /system/framework/framework-res.apk followed by an adb reboot recovery command before you do anything with the phone. From the recovery menu wipe cache and then reboot now. If you don't do this last step it could lead to having to reflash the factory firmware happened to me about 6 times this weekend. DO NOT TRY THIS IF YOU HAVEN'T CLEARED ENOUGH SPACE ON /SYSTEM BECAUSE IT WILL KILL YOUR PHONE!!!!!
For all those who want a pit file, here I leave you a custom pit file created for the sc-02b.
I must make this clear, this PIT file was made for those who flashed their devices with a rom for some other galaxy s version and want to reflash their devices back to the original SC02BOMJJ1 rom. I cannot ensure you it will be useful or that it will work for anything else.
Also, when using this PIT file with odin, be sure to check the "Re-partition".
@shikigamild :
is this PIT file the same that came from komugi.net ?
at the same time, could you tell me how you got the stock rom file links please ?
@dejanet :
so you say that with the Z4mod you have a fully working device ?
has anyone tried the CF-root package ? after applying it I lost my SIM card, so I wonder if you experimented the same kind of inconvenient there
Oh yes went through all of the fun of trying the various kernels everyone leaves you with sim not recognized.

Aaarghh,that sucks donkey balls...
Guess that means we won't get any, custom rom any time soon will we?
I'm new to all this stuff, so apologies for the noob questions.
I rooted my SC-02B using the tool in this thread. I was able to install and use the Barnacle Wi-Fi tethering app from the market, so I know it was a successful root. Now when I go to install and use Titanium Backup from the market, it tells me I don't have root access or don't have BusyBox installed. When I go to install BusyBox from the market it shows my phone as being rooted, but when I tap install it gives me a failed message saying my phone isn't NAND unlocked.
How do I do that? Once I get that problem solved, what are the next steps for installing the Z4Mod?
So far I've never installed BusyBox through the market. Just install it with Titanium and it should work fine (click the "Problem ?" button).
Then, I suggest that before doing ANYTHING involving a custom initramfs (like ClockWorkMod), you dump somewhere your mmcblk0p3 partition, in case you want to restore your phone exactly to the same state you got it.
If your not that paranoi, you can skip this part, but as I wrote myself a dozen times here, I forgot it and would be interested also ^^
Ok, thank you for the info. Does Z4Mod cause any problems with this phone? I read in dejanet's signature that the lagfix seems to cause problems. Z4Mod is the lagfix he's talking about right?

z4mod is just a rooting app. There's no lagfix. He's probably referring to OCLF which is made by the same developer. It's obsolete now, so do not use it.
About the rom problem, can't you just flash the modem from a Docomo rom after installing the custom rom?
No, z4root is only for rooting, but z4mod is a lagfix application. As far as i know, it will convert your phone system to ext2. However, i scare it will affect the DioDict application in SC-02B, so i haven't tried it yet.
Trojan,if you fear losing diodict,you can still dump your mmcblk0p3 partition.
It is the one containing diodict data.
I would actually be very grateful for an upload of that one (^-^)/

Opps. Didn't realise there are two apps with similar names.
Still, wouldn't suggest it. EXT2 is unstable.
Hi, bebert218. Actually, i am a noob, i don't know how to do it. Can you tell me how to view the partitions in the internal memory? I suppose DioDict application contains a database file somewhere in the internal memory, but i don't know where and what the file name is. Appreciate if you could give me a hand on it. Thanks.
Custom Kernel and Roms
From reading through the forums it seems custom roms present issues with the either the sim card or modem on the sc-02b. Are custom kernels causing issues as well on this phone?
Yes it is the kernel that causes the problem. I think a couple of us have tried them all.

disappointing Other than rooting and using Galaxy tuner to do some tweaks there isn't really much else to do. At least the upgrade to omka5 showed much improvement from 2.2
I have rooted my phone using the Onclick rooting software, that seems to have been a success.
However, I tried using teh OCLF from market to lagfix it but nothing seem to have happened in the 30mins I let it do its thing. THe progress bar goes full then start again, and does this repeatedly. And after reading around some people say that's now out dated and other lag fixes should be more suitable
So, now that my Samsung G S is rooted, what options for lagfixes do I have?
Hi, im asking the same questions
Hi, i am in uk running stock froyo 2.2, I have rooted my phone using Z4root, but I want to put a lagfix on, I have read that OCLF isnt very good anymore, and voodoo you have to install a new rom and im not brave enough to do anything like that so which is the best lagfix i can use and i have heard about overclocking what does that mean? thanks in advance
can anyone help us please

Besides the fact I dont know whats a Samsung G S and no idea what your ROM version is you could do what I did. But depends on your ROM and SGS version!!!
But its on all your risk. Read manuals and warnings to the kernel and the app. You have been warned (I have done this on 2 SGS mine and my friends till now , he has 2.2 stock rom and I 2.2.1 stock JPY too)
Took the neldar kernel flasher , backed up my stock kernel.
Then flashed the speedmod CWM version with the kernel flasher, kernel you can find in the speedmod kernel thread.
Applied the tweaks and lagfixes (ext4) from the recovery. done
and that was it. btw when you do this, try to run the rom WITHOUT the lagfixes, just with the new kernel so you can easily get back to your stock. If you want more, then go to the recovery ULK options and do the recommended tweaks from there. If you still need it, then apply the lagfixes (always backup and always on your own risk)

Not sure you have to install another rom, but I do not know the the original voodoo kernel . Maybe you could try with the one I suggested up there.Btw there is more kernels to choose from, depends on your Galaxy Version and ROM.
Overclocking is nothing you should be concerned with yet I think there is a pretty big speed jump from stock to custom kernel, then from custom tweaks and also to lagfixes. If you are not satisfied then you can try that. OC should make the phone faster. In my opinion though the 1GHz is enough for the phone. With OC come some risks (heat, battery usage, stability)
Last night I managed to get the OCLF working on the phone and noticed improvements. Now that I have a lagfix working, will OCLF be alright to leave on there? Or do you still recommend going to somethign else? (I didn't quite understand why OCLF is being considered out dated anyway).
Install the new version (2.2.1) and lagfix is of no need anymore.
Completely satisfied with a smooth running Galaxy now.

Well keep the lagfix you have now. If you wanted try something else you would have to undo the changes you have done till now. If it works and you like it keep it..
To plexat: yes the 2.2.1 it's sufficient in speed.
In my case though I had to do already 2 factory reset once cuz the phone didn't start at all and in time even the 2.2.1 became slow. I installed the custom kernel though just for the sharpness fix but was surprised with the lower battery usage and speed. There is still a big speed jump from stock to custom

Ok man, first of all. You have stock 2.2 but which phone exactly?
In the kernel thread, is written for which phones it is and also for which ROM.
So if it fits yours. You can try what I wrote you somewhere up. Backup, flash the CWM version etc.
First make sure though if you have the correct kernel for your ROM and phone. AND you shouldn't have any other type lagfixes applied.
Thats kinda all. What you can do if you have root, without any trouble, is backup your kernel with the app. Then verify if other things fit. And you can try to flash a custom kernel.
EDIT: Why are you still on 2.2? I mean UK had as one of the first 2.2.1 and plexat is right. 2.2.1 is faster and smoother as 2.2 ? If you dont have any lagfixes or other custom things applied you should kinda update to 2.2.1
Hi Pagot, I checked I had the right kernel and stuff and YIPPEE ive done it, my heart was in my mouth but i took the plunge and it now says i have the kernel above, it does seem more responsive and quicker although the benchmark still says the same? the reason I have still got 2.2 is because I have a branded o2 phone and they havent released it yet for branded phones and i am scared to try and flash it to 2.2.1 is there anything i can now do to speed it up anymore ie lag fixes and things thanks for your help
Glad it worked for you
Well not sure about upgrading the rom with a custom kernel. Am new at this too . So dont flash a rom yet.
From what I asked in the speedmod kernel thread. It should be safe to put back the stock backup kernel you made with the app and then to update if its out. Thats just for 2.2.1 upgrade for you in the future. The condition is however no lagfixes applied!!! If you have them applied it can and will probably go bad on the update!!!

Ok please dont look at the score. Mine is actually worse as on the stock kernel if you are talking about quadrant. They are irrelevant.
If your phone feels right, leave it as it is
If you want to tweak it little more. Get to the recovery and there are some tweaks,should be still safe to make. They are marked as recommended in the ULK options.
I wouldn't suggest yet to apply a lagfix. Try it how it feels now. If it starts getting bad and laggy etc. Then experiment with that. I had a lagfix but reverted back, for me the speed is sufficient how it is now
Since you have now CWM you can even backup your whole phone.
If you dont know how to go to the recovery the 3 button combo. There are many nice tools in the market for that. I personally use SGS toolbox/tools, in it is a shorcut with reboot to recovery.
When you are there. the BACK button is actually like OK so beware of that!!! You navigate with the volume button UP/DOWN and confirm with home or back.
Thanks again, been in and enabled tweeks, just so as I no, I noticed in recovery there is a lagfix option is this where i go to apply this and if I do it how do I disable it if I want to
Also you said I could backup my phone now how do I do this Thanks again
Wow my phone is really speedy now thanks for all the help I've now flashed kernel tweaked and applied lagfix and all is well I've backed up my phone as well

Ha seriously glad for you . One day you have no idea about anything, the next day you run a custom kernel with lagfixes and tweaks.
When you get to it, its kinda not so difficult. (It took me kinda a half year )

How true. Just in case get familiar with Odin. Having fun with flashing by CWM can sometimes result in being stuck. Knowing how to use Odin and having all necessary files on your computer should give you some sense of security.
Hey guys. I just rooted, flashed a new ROM ( newest CM7) onto my p970 last night, so yeah, I'm a total newb and so much confused about these things. Apparently I saw a thread about kernels and that they kinda improve performances and stuff, so I tried installing them. And now my phone is in boot loop state and I can't boot CWM to reflash the original kernel. I used Huexxx's kernel from this thread.
http://forum.xda-developers.com/showthread.php?t=1332311
So I'd be really grateful if someone could link a thread on how to fix this, or a step by step guide. And I'm totally new to this forum so I'd like to apologize beforehand if I break any forum rules and the likes. Thx.

| Thx for the reply, really appreciate it. Man there are a lot o' things I need to learn
| btw, if you don't mind answering, it seems that the phone gets real laggy after a an hour or so of turning it on. I've checked the apps and made sure that none are eating up the phone's memory. Is it just me or does it has something to do with CM7?
Hope you dont use any memory cleaner or other "tuning" software, since this mostly only messes the phones up... Mine runs fine, so I guess it is a problem on your side. I always recommend fix permission from within RomManager, cause it often solves/solved problems. I also always move all apps to SD card, inside of App Manager (the stock one, not anyone from market) cause it saves space and resources for the phone.
Did you mess around with cyanogen settings? Which governor do you use? Maybe use SetCPU or NoFrills or similar? If so, uninstall it.
Simply list all your apps, if none of the given tips helped And do a reboot all couple days, since it seems to be good for the phone
I was able to root my captivate, my specs are: 2.3.5- 1897UCKK4- kernel 2.6.35.7-I897UCKK4-CL614489 Gingerbread. Downloaded ROM manager and it doesn't list captivate when I try to flash clockworkmod, why? Also have OCLF and when I try to lagfix it says I don't have playlogos file. Can some help me out here. I am fairly new to this, but I think it has something to do with EXT2 not being EXT4?
Don't use ROM manager. You need to flash a kernel that has CWM baked in. You can find one in the dev section. Also, I'm pretty sure lagfix is not really used anymore

gj23, Thanks for listing the fw versions of your phone, I'm interested in how you were able to root your stock 2.3.5 Captivate. I have tried three the following root methods and all have failed.
1) Super1Click, freezes during su from file system errors in logs.
2) update.zip to sdcard, fails with file signature not recognized.
3) rageagainstthecage.zip, fails to reconnect to PC after adb disconnects; or terminal emulator freezes up.
So I'm wondering if AT&T didn't make this build harder to root.
Is there a rooted mod compatible with this phone build?
If so, Can I use a rooted mod and flash it without being rooted first to get root permission?
I have searched and read so hopefully I'm not wasting anyones time. These are my phone specs.

Im trying to run 2.3.5 stock with lagfix
This is the only forum that comes close to my question.
what i am trying to do:
Run 2.3.5 Gingerbread stock (i have to official kies mini release)
apply a lagfix
debloat.
but i always get a random reboot effect.
i took a look into the Fasty Rom but the DL links are dead.
since this was the only rom that seemed to appeal to me right now.
I wouldnt Mind a Deodexed rom. but i want to keep it as much of a stock as possible.
I am still learning the captivate ways since this was given to me and i use it as a tablet.
the stuff i use.
I897UCKF1-AutoRoot-DesignGears.tar
CornKernel_UCKK4_v706.tar (v705 also causes reboots)
my potential problems are
init.d
CWM (kernel)
and debloating (have gotten cases where the reboots dont start till after i debloat.)
any information might help since ive searched google and the androidforums website.
but the lagfix seems to be intended for 2.2 and 2.1
EDIT:
ima be trying this in the mean time.

As you probably noticed, Corn is probably your best answer for what you wanna run.
If you're looking into something with better performance, I'd suggest a JB ROM. That being said, this device will only go so far which the hardware it has.
Any recommendations?

if this is true about the performance, how noticeable would it be?
and what Jellybean Rom Would you suggest that could give me a balance of performance and battery life?
which is something im going for right now.
so far the specs i have are running great but if there really is a way to boost my performance by more then 30% it would be a welcoming sight.

You won't get much more than what you're getting atm cause like I said, the hardware can only go so far.
As for ROM, we don't make suggestion (to avoid flaming). If you really wanna take on a JB ROM, look them up and choose the one that suits your style the best.
i see then...`

oh, i see.
its hard to find all of them since theres so many threads with ROMs.
ill try and take a look. but it seems like it would be just more time spent on it then it would actually be beneficial.
Hi,
I was quite happily running ICS4.0.4 (rooted) when I decided to try a different ROM (and/or JB - can't even remember any more).
After I did a wipe (I know, I know!!!) it got stuck on the boot logo screen.
I had the phone fixed by a 3rd-party repair shop, who installed ICS4.0.3 on it and, while at the shop, I used the phone a bit to make sure it was ok.
It kept crashing intermittently, so they had another go at it and now they tell me they could only install GB on it.
So, keeping in mind that the phone had the emmc bug and I tripped over it:
Is there anyway I can install ICS again on it?
I could use some of the tools floating around to detect damaged partition blocks and work around them.
What procedure should I use to go from a stock GB (non-root) to ICS?
Specifically,
- is there a safe way to root GB (given the emmc damage already), so that I can flash the other ROM/kernels (below)
- what kernel should I use
- what ROM should I use
I would greatly appreciate any help on this. I have been eating humble pie for a week now, so I hope there is no more 'why didn't you pay attention' coming my way
Cheers
You could use hydracore kernel which works with all GB and ICS ROMs and JB none Tw ROMs I be leave you can flash with PC odin to gain root and is a safe kernel

Thanks ttibbetts83, I will try that and see how i go
Thanks Arobase40.
I'll get a strong coffee and read your reply from top to bottom and then plan my next move.
The repair was done by people unrelated to Samsung.
I currently have GB v2.3.5, (SGN_XX_OXA_KJ1_FACTORYFS) which works well, it would seem.
I'd love to get ICS back on it but need to gather info (such as that from yourself) before I do anything.
A bit more info on the state of the emmc storage: Using 'adb shell' and executing the command DD did in fact find bad blocks in partitions 9-11 (can't recall right now exactly which ones), so there are issues there.
The partition that is in place now, __appears__ to have successfully skipped those bad blocks.
And on something slightly tangential to the current topic, I know that doing a 'WIPE DATA' from the recovery menu zaps emmc, but does that also happen when you do a factory reset from within Android? From memory, when doing so, it seems to go into recovery mode and do it, so I'd expect that it'd also damage emmc.
Cheers

As opposed to all alarmist and contradictory posts about eMMC bug on stock Samsung ROM : GB or ICS, I never got any issues with this so called eMMC bug and never got bricked G-Note as long as I kept at using the stock kernel, nevertheless I made various and numerous wipe whichever the ways (from recovery or the settings)...
For rooting, I always used the temporary Touch CWM to flash (which has been may be removed from XDA, I guess as it was supposed to cause bricked devices) anything : superuser, busybox, and other custom ROM... ^^
BUT when I flash a custom ROM, I always removed the custom kernel (so called "safe"), and replace it for a stock kernel and never got issues with it.
The first and last time I flashed a custom with custom kernel I got my G-Note bricked (just forgot the replace the custom kernel for a stock one... ^^) !!!
So, if you want to flash an ICS version, get one from Sammobile, and flash it with PC Odin !
You shouldn't have any problem with them !!!
Get all root and busybox files from dr Ketan, and if you can find it again use the temporary Touch CWM which has NO kernel inside : it WORKS quite fine !!!

Unfortunately there are no high trees on XDA beause you should look for one before typing this utter personal nonsense that could brick anybody's Gnote.
Taking your own convictions for thruth is one thing, sending innocent ppl into the jungle is another...
What you are saying is: If there is a lightning storm, just go into an open field en enjoy. I cannot say it is 100% safe, but I never got struck....I think they removed the tree i used to seek shelter from the rain, but if you search real hard you might find it anyway.

Actually you should be happy that they revived your Note after brick even if it's only running GB for now.
However if you are a brave person you can do the same trick on ICS.
Just read and understand the thread that is a guide on doing so.
You can root your GB without a problem, but there is no obligation for it to install ICS with odin.
However what you do need is the following (besides a lot of patience and courage) :
1. get the ICS files you want to flash including the pit file.
2. get a program called PIT MAGIC to recreate a suitable pit file
3. determine where your bad blocks are located
4. Load the pit file into the magic program and alter the stock pit file
with the values needed to ommit your bad emmc area
5. save it and then flash your note in odin with your newly created pit file and repartition ticked.
@OP: could you please check your internal storage capacity? Is it aroung 8GB?
Arobase we are not going to rediscuss this matter for another 556643 pages.
Just ask yourself : if there was no problem then why did samsung patch their JB kernels for it. http://forum.xda-developers.com/showpost.php?p=34933643&postcount=683
Also nobody asks you to reconsider your own experience and beliefs, but the day someone follows your instructions and bricks his phone, are you going to pay for a new motherboard ?
I'll stop this discussion here, and just hope nobody will get struck under the tree.
