Hey, guys,
I'm talking about this thread http://forum.xda-developers.com/showthread.php?t=1633943
Are these issues resolved somehow? I'm sitting on ICS Stunner ROM and I'm afraid to do anything serious with my phone.
Shouldn't there be fixes when Samsung released official AOSP source of Notes' ICS?
Or am I missing something? I really want to do a completely clean install of some ROM, because my current ROM (the newest version of Stunner) works terribly, forcecloses, slugish, freezing all the time.
Can the behavior of my phone have something to do with the problem discussed in the thread I linked? (I don't understand anything in that thread )
Hi
The issues regarding superbrick arent completely resolved. But there are Kernels for ICS wich contain a workaround. And so far noone has reported bricking with them.
It seems like the official kernel source from sammy still contained that bug. But now it has been bypassed. Still noone is completely sure yet that they are 100% safewhen it comes to wiping etc.
There is also a workaround to repartition the data section effectively bypassing any damaged areas for anyone that has a brick and no warranty.
This of course reduces the data partitions size, and it's still pot luck as to how much damage would occur.
It's also a pretty tricky operation.

So if I want to install a stock ICS rom (the newly released one, not the old leak), I should dooo, what? Which is the safe kernel (the one with a workaround)?..
Sorry for stupid questions..
Probably worth flashing stock ics ROM, with a custom kernel that's safe. Probably best to do it in mobile Odin. Make sure you extract the firmware file and only select ROM partition, then separately point to kernel.

I think its better to be in Stock rom what we got and never do any experiment, instead of wasting time on it to get very little stuff with high risk.
even if some work around solution is there, its very hard to understand and not all will be doing that.
I totally agree. Wait for safe ics kernels or use modified Cm9's for now.
Sent from my GT-N7000 using xda premium
So just to be sure:
I use this ROM http://forum.xda-developers.com/showthread.php?t=1646088
And a kernel? You mentioned CM9 kernel. How do I get it? Can I find it in here http://get.cm/?device=n7000 (I mean is it somehwere in the .zip?)
Or are all those franco/abbyss kernels also considered relatively safe?
Thanks for your patience
No you cant use Cm9 kernels with stock rom. If you flash a stock rom you get a stock kernel included
What if I flash chainfires kernel first and the flash stock rom?

No, either use a GB kernel or use Franco's #3+, or SpeedMod K3-3, CF's ICS kernels are NOT safe.

Hi there! I'm new to the forum and to android as well.
As you can guess I'm a proud owner of SGS
Since my SGS sucks a bit (random crashes, reboot, RFS) I'm interested in taking the maximum out of it, and I have some questions.
What is the difference between kernel and a rom? As far as I know from Linux and OS theory, kernel is the layer between the user (applications) and the hardware. I also know that most of the ROMs have kernel in them. Then what else the ROM contains?
What is firmware? Is it used a synonym for kernel/rom?
Is it worth installing custom kernel/rom on SGS? I'm a bit paranoid in those things and have some fears about the issue.
Is there a way to install some good kernel (like speedmod) and naked ROM (not someones mod, i.e. a stock android ROM without any additions from third party developers)? Is it hard to make my own ROM based on stock ROM (without touching the kernel, even tough I looked at the code and read books about the linux kernel, I dont yet consider my self a guru to be able to make my own kernel for android), just the modification and custom applications?
Thanks a lot guys!
Everyone has a kernel - even if you don't mod your phone at all. It wouldn't work without one!
Now, if you flash a ROM, you change the whole system including the kernel. If you flash a kernel, you're only changing the core piece of your system.

A rom is a full firmware .
A kernel is the bit at the base level between processors and OS .Or just as you said .
Is it worth installing custom kernel/rom on SGS? I'm a bit paranoid in those things and have some fears about the issue.
YES but its at your risk though SGS is relatively un brick able .
Simplest upgrade would be via Rom Kitchen and build your own rom .
Choose base rom kernel modem and CSC to suit plus themes and apps .

The kernel in android is essentially just a customized Linux kernel. The ROM is basically the application layer and the framework. Usually ROMs include kernels, but you can flash a different compatible kernel.
Firmware usually refers to either all the basic software on your phone (minus the apps) or the ROM, csc and modem.
You can definetly flash a custom kernel onto a stock ROM, which will improve performance a great deal even without a custom ROM. Find instructions aplenty here on XDA.

By un brick able you mean that its hard to brick it, or if I brick it its hard to un brick (fix) it then?
Also I'm having a hard understanding, if kernel is the thing that manages the hardware and also responsible for lagfix then kernel is really what matters for the performance of the phone. How a ROM could improve phones performance?
Also one more questions:
As I understand CSC and modem are connectivity related files (3G internet, APNS etc) right? So its better not to touch them when flashing custom ROM/kernel?
Thanks a lot again!
JJEgan means it's really hard to get to brick your SGS.
The kernel is responsible for the proper functionality and cooperation between hardware parts. As for SGS, it is a common belief that Samsung's RFS is not as robust or "agile" as ext4 FS. Thus, converting RFS to ext4 should increase device's performance (the time needed for the read/write operations to take place is decreased). BUT, in order for the device to function properly, the kernel MUST support ext4 as a file system format otherwise it won't work anymore (This could happen after installing a stock kernel on a device that uses some filesystem apart from rfs). Samsung's stock kernel does not, so you have to replace it, if that's the case.
(E.g. If you format a USB drive under Windows 7 with "exFAT" as its filesystem, you won't be able to access it through Windows XP for example, because XP does not support "exFAT" - Different kernels & Different OS version ).
Yes, CSC and modem.bin are what makes your device a TELEPHONE, too Connectivity issues between your operator and your handset depend on those files. If you can find the latest COMPATIBLE modem file, then go for it.
Thanks for the explanation!
As for CSC and modem, by compatible you mean the same version (XXJPY for example)? How do I know they are compatible with my phone?
Thanks a lot again!
the CSC doesnt have to match the baseband. for exapmle, you can have XXJPY baseband and XXJQ1 modem. (thats what i used to run)
its all about finding the right modem for your region, you want to make sure you get good connections dont ya ? modems affect SMS, Calls, Data, WIFI, so on.....
so you want the right one. If you go to rom kitchen, you can see all the modems and what region they cover
Thanks!
But is there a way not to touch the CSC/modem when flashing custom kernel/ROM? I'm really afraid to mess with those.
Also could someone refer to this question:

Think of the kernel as the drivers and the ROM as the OS. If your drivers are from 1987, windows 7 wont run well, if at all. However, you can have the newest 2011 drivers installed on Windows 95....same thing. Kernel and ROM must be well suited and work together for a good experience.

Actually if you are flashing a three file firmware with odin, PDA is the ROM, which in this case usually includes a kernel.
If you are flashing a kernel alone onto an already installed ROM, then the kernel is put in the PDA field.

Gingerbread needs a different kernel than Froyo, right?
every firmwarerelease (JVQ, JVP, JVR, JVS, etc..) has its own kernel version.
but with talondev im not sure, cuz there is no distinction between the kernel versions.
with all other custom kernel releases you have specific kernel versions.

Actually most custom kernels can work with any firmware build for the same version, froyo or gb. Some devs may base a kernel on a specific firmware, but they usually work on all.

For custom GB roms, I have tried Rocket rom and the newer Litening rom. In my opinion, both are great and definitely worth considering.
For the GB, I have tried DarkyRom, ChrackRom, CheckRom, Cassie's XtraLiteRom, and Litening Rom. I found them very comparable in performance and battery life. For ChrackRom you have option to install a full, small, and extra small rom. I am using Litening Rom right now. I might go back to ICS Stunner rom, I like the Stunner rom except that it is not as stable as the GB roms in my SGN.

I really like ICS Stunner too, but you might want to exercise caution using that or any other ICS LP5/LP6 leak based ROMS until an issue with potentially hardbricking your phone during flashing is resolved.
If you're interested, there's a still experimental (but as far as hardbricking safer) ICS CM9 build that's really cool over here:

Hiya there ! I'll seize this opportunity to avoid creating a post of my own then ! I'm like Arasl, though i bought my GNote in february and i'm still running a non-root, stock ROM because i'm sort of "afraid of flashing".
First, i've never done it before, and since i'm a Linux user i've been searching for ways to do it through linux instead of the Odin/windows method but i'm now pretty much resigned to use Odin (seems simpler, methods actually do exist and there's more feedback, though any hint towards linux-oriented methods would be great).
I've restrained myself from flashing ever since i saw the brick-related posts from ICS Stunner ROM and i do NOT want to flash that ROM.
My questions are then following :
1) Is it possible to ROOT the phone without flashing on Kernel version 2.6.35.7 - N7000XXLC1 ?
2) If it is unsafe to flash ICS-based ROMs, is it 100% safe to flash gingerbread-based custom ROMs or is there still an important risk of bricking the phone?
I can imagine most people will answer yes to the previous question and in that case, which ROM would you advise that is both light (and smooth, since the stock ROM is a little laggy on the edges) and the most battery-saving?
Thanks for any hints to existing posts, i've been looking around but i just don't have the time to read the hundreds of pages of custom stock roms to compare them all by myself ;-)
Just use the latest cm9. Very safe and beautiful. If you need the spen functionality then use gb..

If by any means you are ready to work on windows, i would gladly help you in all these...although in a RISK on anything happens on completely you only.
I, too as being flasholhoic, flashed almost every ROM here in the development section both GB and ICS, every kernel, so i will try my best to avoid any risk but god-only-knows-the-best. As per your question,
1. Yes you can root your stock rom without flashing on Kernel version 2.6.35.7 - N7000XXLC1, Go here and select the right kernel and follow the procedure.
2. Official CM9 is the only (yet most) safest ICS build here, the rest being suffered by the ultimate phenomenal hardbrick bug. And yes its safe to flash any GB rom until you are switching it from GB to GB rom only.
The most important thing, take enough time to read read and read (even query) the instruction before flashing anything, or else you can have ample amount to time to read anything with coffee placed on your new bricked note. Choice is yours.
Hello, relatively new android user, and new (German) Galaxy Note owner here.
I've used one other android phone before (Galaxy W), but since that one is my business phone, I can't really toy with it much.
First thing I did after getting the Note was doing an OTA update, which of course netted me the hardlock-bugged LPY kernel, which I didn't know at the time.
There's quite the collection of safe Kernels around, but I'm not sure which one is the correct one for me.
I want to wait with flashing CM9, since I sorta like using the FM function, and afaik that doesn't work in CM9 yet.
I'm fairly content with the current stock ICS aside from the hardlock risk looming over my head like the sword of Damocles.
So, since the selection of Kernels overwhelms me a little, my actual question:
Is there a safe Kernel that just runs with the stock ICS ROM without any other changes that I can flash on and be done with? Or will any safe Kernel neccessiate a wipe/data restore/whatever?
Try franco kernel.Used to use it with GB but have since switched to CM9 kernel as I no longer use Samsung based ROMs.Read this, everything is here.Then reread.Then decide what to do.Do what you decided
Thanks for the response.
After reading through the most recent pages of the franco thread, that one seems to be unstable in recent builds, though. I use the alarm clock, so I don't want a phone that randomly reboots at night.
I guess I'll try going with Chainfire's Kernel instead. Wish me luck with my first kernel flashing on an android phone. D:

Since I can't post on the speedmod thread yet (dev board~), I'll ask here: Will I have to factory reset if I want to avoid complications (I have titanium backups of everything), or can I just let it run like this?

shouldn't have to wipe data or anything for flashing a kernel.
Speedmod is the bomb. I tried franco but it messed up my wifi.
Part of what has me asking:
I flashed ICS from GB via OTA, but didn't do a reset back then (thank god), because I read about the hardbrick bug just in time.
Seems at least some stuff doesn't quite work right after that. The Software-Update widget that comes with stock ICS is an example of that. I'm not sure what else may be glitched.

Go to a CM9-based ROM. You won't regret it. Stable, smooth, solid.

hello, I have just recently got into this flashing of custom roms and kernels ect, ive flashed quite a few roms and recently discovered that my phone has the dangerous eMMc chip. To reduce dangers would it be best to return to stock and unroot my device? to be honest id rather return right back to GB. Is there any way to do this safely?
Currently have: GT-N7000
Rocket rom V6
Franco Kernel
You have four options:
Option 1: keep what you have, it is safe enough.
But since you already prefer not to keep what you have, you can:
Option 2: flash a "safe" kernel (e.g. Abyss), this will keep ICS. Search for "Abyss kernel" to find thread.
Option 3: go back to GB and stay there. Get all you need from here (flash with Odin):
http://forum.xda-developers.com/showthread.php?t=1424997
Option 4: go back to GB, but then flash another safe custom ICS ROM, e.g. Paranoid Android.
To do this, perform option 3 first, then flash custom ROM. Full instructions here:

hey man relaxy. You dont really need to worry because even though you have this bug on your device, you are currently running Francos kernel. This is a safe kernel as it has the eMMC_Erase functinality disabled so even if you wipe/factory reset your phone a hundred times it WILL NOT get bricked as long as you are running francos kernel. All GB roms are known to be safe from this bug as well but since you are already running a safe kernel on ICS you dont really need to downgrade to GB. You also much be having root since you are running fracos kerenl so i recommend that you keep this config!
Oh, well if its safe then I might aswel stay with it. Another thing though, I was planning to undervolt my device to save power and stop it getting as hot as it does. Seems francos kernel doesn't support this. What can I do?

Hmmm...as of now im not sure if there is any safe kernel which does support OC and undervolting. I think CM9 Knightlies Kernel might support it...but im not too sure. Just do some research into it. But if your looking for great performance and good battery life then i recommend Speedmod Kernel. Its a safe kernel and very stable the battery life seems way better than stock.
http://forum.xda-developers.com/showthread.php?t=1673072
This speed mod kernel seems to be okay, does it support undervolting though, that's my main concern and only dislike about this device is that, it gets too hot. If this kernel will let me do this, then problem solved. I guess there's no harm in trying it. Since I'm flashing it through CWM from Franco kernel.
i dont think it can do undervolting. try goku kernel.

Why do so many developers suggest to revert to stock ROM before flashing another ROM or a new version?
This is widely suggested and I see no reason for it.
Of course a re-format and all cache wipes are mandatory.
A ROM upgrading procedure is deleting everything as a first step, or?
What i reckon is JB custom Roms were mostly tested to be flashed coming from a previous Android system ICS (and of course ICS from GB). That's the reason why many users experience post installation problems like invalid IMEI and instabilities when flashing directly a JB Rom coming from a GB.
It's always best to follow the recommendation of Developers who built our custom Roms, they know better.

The most common developer's advice is to first flash a stock GB rom and afterwards load a new JB ROM.
I still see no reason for it. Once a new ROM is flashed everything (what was before) is wiped, or?
The only reason I see is to make it safe for the ones which do not follow the fromat/delete all caches procedure...
Still silly to me....

Elitemovil reccomends this. I'm running this ROM and want to upgrade to new version with new Partition layout.
Anyway, we are loosing the point here - I still see no reason to make any "intermediate" steps before flashing the ROM which I want.
Anyone knows the answer wha there might be problems from swithching ROMs immediately?
