Hi all
Is Nandroid backing up all the apps I've got at that moment? Or it just saves system files?
Like a complete and exact "photo" or are there things that I should do on my own if I mean to recover exactly as it was...
I assume that no wipe is necessary...
Thanks!
What's the truth about Nandroid backup?!
i guess there's no need to open a new topic, because i got kinda the same question
before you guys start to redirect me to the "search" function, i want to assure you that i have been using it, but i have found myself in a very strange situation, one question, two different answers... and because i'm new to the whole root stuff, i want to learn everything correctly before starting to make modifications to my phone
The question is: Nandroid backup, does it also back up the kernel or not?
I mean, if i root and install a custom rom that also comes with a custom kernel, will i be able to use my previous Nandroid backup to restore my phone to the old rom & kernel?
Searching the forums, i have found 2 totally different answers!
Answer 1: Nandroid does not backup the kernel: http://forum.xda-developers.com/showthread.php?t=806340
Answer 2: Nandroid does backup the kernel: http://forum.xda-developers.com/showthread.php?t=844352
So, please make me and all of us root noobs understand once and for all, does it backup the kernel or not?, will we be able to restore from a custom rom+kernel in case we need to?
and does it backup apps?
OK...As I understand it....
What does Nandroid Backup?
The ROM Itself..Obviously.
All your system settings, emails, SMSes, etc
All the Apps you have installed, so no need for TB
The Kernel you have installed (though there is controversy about this, and to be honest, I have never restored a nandroid backup when I had a different kernel already installed...however it really doesn't matter since kernels are easy to flash)
What does Nandroid NOT backup - This is VERY IMPORTANT
The modem (not a big deal)
The File System setting (A BIG DEAL)
This I think is where the confusion arises concerning the kernel being included in the nandroid backup. For many people the kernel is all about the lagfix. If you have installed a lagfix on your phone via the kernel, say changing the file system to Ext4, and then flash a Nandroid backup that includes a stock kernel or other kernel that does NOT support Ext4, you are in for a world of hurt...and in this case hurt means endless bootloops.
The way you avoid this is, if you need to flash a Nandroid with a kernel that does not support your lagfix...go into recovery, disable whatever lagfix, tell it when it asks that you wish to REBOOT INTO RECOVERY after the change....then flash the nandroid you wish.
This is why it is very important to keep regular nandroid backups, and to wait and see if a ROM/Kernel are stable for you before applying lagfixes or other tweaks.
So, let me see if i got this right, Nandroid does backup up my current kernel along with my rom, but if i apply any changes (lagfix) to my kernel afterwards or change it with a custom one with lagfix, nandroid won't be able to restore it anymore...
so the whole problem here is that nandroid is not able to backup / restore The File System setting, this being the rfs / ext4 transition
If this is the case, it seems that the Nandroid type backup is not as powerful as i thought, you can't really change from one rom to another in just a few clicks, but then again i guess that all the customs roms already come with some type of lagfix and you can make a nandroid restore between them, the problem would be when you want to revert back to a stock kernel, then you'll have to disable the lagfixes or simply flash a stock kernel and then restore the stock nandroid backup
so, i got this right guys?

Yes as I understand it.
You see Nandroid can't convert your file system or change anything, all it can do is flash a disc image onto your phone. If that image can work with your file system, you are golden. If not, it is like flashing a Mac OS image onto a Windows machine....nothing will work right.
However the good news is that most custom kernels support Ext4...so really the only problem comes when you try to flash back to a stock image...or vice versa.
got it then, thanks for your answers
and, if i still got your attention, maybe one more question
i just downloaded a stock firmware from samfirmwares.com, and all i got is a .tar file, can i use it somehow to flash just the kernel from it or i have to flash the whole firmware?
if i flash the whole firmware, will it also change my PHONE and CSC?, because the .tar file must be put just in the PDA section in odin

Yes, it will flash the PDA, csc, modem and kernel...the whole shooting match. The single file firmwares are designed like that to avoid mismatches and issues. Once you flash it, flash a kernel that supports cwm (I suggest speedmod or something by CHAINFIRE) via odin, then flash a new csc and modem if you wish from recovery.
Remember that installing a new csc will do a factory reset so do it before reinstalling apps.

great stuff man
finally i got enough info and i can start my root & flash procedure, guess i'll also learn a few other tricks along the way, this community is definetly the place to be if you want to learn how to "really use" your device
the whole info about the issues with the Nandroid type backup should be integrated in one of those massive info topics, so the root noobs like me know what they're dealing with

Hey guys i actually used the search button (yay) and this is definitely the most informative one regarding the topic.
However i still have one more question: does it backup files and folders as well? Ie. my Nexus S storage is mainly used up by my videos and music (about 7-10GB) which are in their own folders and not tied to any apps in particular. Hence if it does include those i wouldn't have enough storage space to create a nandroid backup am i right?
Edit: thanks to the search button i didn't realise that i posted on a Galaxy S forum please forgive me, the question should still be relevant to the topic though

As I understand it, it does save folders and files, so yes if you have large data folders on your internal SD it will make GIGANTIC nandroid backups. You may want to store such files one your external SD.
I know that there is a version of CWM that does not backup /data/media in Nandroid on the Galaxy Tab 10.1...perhaps there is something similar that I don't know about for Galaxy phones. Does anyone know?
My goal is to get to the latest ICS stunner with full root and flash counter remaining at NO. I am currently at a not-directly-rootable stock rom.
I have read the pre-rooted ROM tutorial thread, the ICS stunner thread, many various threads about flash counters, how to ensure proper root in ICS, etc, I just wanted to make sure that I did not miss something compiling this information so to speak.
I have never rooted or flashed a rom before, please please do not assume that I know 'basic steps' for flashing.
Could someone please check over the following procedure I plan to perform to achieve my goal.
Here is the procedure I want to perform:
1) Flash a non-wipe pre-rooted GB rom using PC odin. Check for root by copying file into /root directory after changing permissions. Change permissions back.
2) Use a backup tool to back up /EFS (these require root).
Q- How can I make a NANDROID backup? Sorry, I did search
3) Buy Mobile Odin Pro
Q- Mobile Odin Pro will NOT increase flash counter, correct?
4) Use Mobile Odin to flash Chainfire's ICS repack of the original leaked chinese ICS rom with everoot enabled (this step reported to increase chances of full root). Check for root by copying file into /root directory after changing permissions. Change permissions back.
5) Go into CWM and flash ICS stunner and it's modem. Check for root by copying file into /root directory after changing permissions. Change permissions back.
Q- Where exactly in these steps do I wipe the davlik cache? Where should I wipe other sorts of data? What is the davlik cache exactly, and suppose I wipe it and don't flash another ROM immediately after. What would happen.
I have accepted that I will be justifiably abused for asking some of these questions. I accept this so that I can do my best to keep my Gnote safe
Finally, does anyone have any additional suggestions? Anything? I am particularly interested in finding some app to take over the screenshot annotation, as I am already satisfied with Jotter to replace S memo. According to some videos, the latest version of Stunner doesn't come with teh replacement apps anymore. PS Touch is great, but I would like something a bit more lightweight, just to launch really fast and scribble 'edit this to use as ringtone' on a Pandora screenshot, etc.
I know how you feel as I was worried crazy the first time I flashed. I can't answer all of your questions but would recommend you read Dr Ketan's post first. I would then:
1) flash an earlier version of GB that has CWM then root using his method.
2) backup using CWM boot into recovery then do backup (AFAIK this is Nandroid backup)
3) Stay with the ROM for at least a day to make sure all is OK.
Then good luck with rest. I have not been brave enough to go to any ICS ROM as there seem to be too many issues and cases of bricking. According to the gossip the official ICS is due next week (maybe two) so will wait until the devs have that version before I do.

I have a Samsung i9000 which I have rooted with super one click details of my phone are:
Model: GT-I9000
Firmware: 2.3.5
Baseband: I9000NEJVB
Kernel: 2.6.35.7-I9000NEJVK-CL649158 [email protected] #2
Build No.: GINGERBREAD NEJVK
My question is this Can I flash this phone with any kernel or does it have to be specific to any of the numbers above (which I do not know what they mean) and if it does have to be specific could someone please tell me which kernel/s are compatible
Many thanks in advance

If you want root with proper CWM recovery you will most likely need to flash a kernel with Odin.
SuperOneClick gives you root for things like apps but you generally still have 3e recovery and you end up with signature failure whenever you try flash something from CWM.
In terms of kernels the easiest one which is closest to stock is CF-Root.
http://forum.xda-developers.com/showthread.php?t=788108
You generally want the same cf-root kernel as the last three digits of where it says gingerbreadxxx.
The rest of the instructions are in the first couple of posts. Fairly long but if you just read it slowly and go step by step its fairly easy.
Once you have flashed this you should have the correct recovery to flash other kernels & custom roms.
NB: Before you start all of this make sure to back up your phone. I would recommend connecting phone to pc & copying entire internal sd card straight to a folder on your pc. Also make sure to back up EFS folder. This is where your EMEI number is stored and you will want this if something goes wrong.
From Cyanogenmod Galaxy S wiki page:
Before you do anything — Make a backup
Don't forget to back up your data. If you have synced the device with a Google account, then the contacts, calendar, Gmail, & select other Google-related data will not be lost and will come back after the next sync. However, you should backup anything you want to keep that is not stored on the SD card:
SMS/MMS messages, Call Log, Bookmarks, Applications; use Titanium Backup or the Astro File Manager, for example, Any application data not on the SD card.
It would also be a good idea to backup everything stored on the SD card in the rare case the SD card must be formatted to resolve any major problems.
MyBackup Root, SMS Backup & Restore, and Call Backup & Restore are all free applications that can assist with backing up your data.
Hi, welcome to XDA man
Firstly everything scubadude said above is fairly important
Secondly; well it really depends on what you're looking for mate. If you just wanna upgrade your kernel (and by the sounds of it you dont really know what a kernel is, or what it does) then flashing a kernel only does so much on a standard rom. Flashing CF root kernel gives you proper root for root apps and clockworkmod (CWM) recovery so you can flash addons and suchlike.
However people usually root their phones so they can install a custom rom, which can improve speed, battery life, functionality and a ton of other things, and that's when people start looking around for different kernels which complement their current rom.
Just wanting a kernel with your stock rom doesn't make a whole load of sense. A ROM is what'll improve your phone.
If you want all the benefits of rooting, i'd suggest looking for a new ROM and flashing that.
If you're unsure of what rom to flash, read around in the i9000 development forum and read through different roms features. You could flash an android 2.3.X rom which would be a gingerbread (GB) rom or an android 4.0.X rom which would be an ice cream sandwich rom (ICS)
Dont ask which is the best rom for GB or ICS please, there are a billion threads like it, and it always comes down to this; read around, look at the features each rom gives, look at any bugs they may have (ICS roms probably have a few bugs here and there where most GB roms are completely stable) and decide if said ROM is good for you.
If you want a very stable, very fast, decent battery life and easy to flash GB rom then i'd suggest Gamerzrom. I'm running it atm.
However the dev stopped developing for it, but i can link you to ALL the files you need to flash the rom and a set of instructions if you'd like. I have a copy of all of them because i flash new roms but i usually go back to it anyway.
Definitely read the development section, you'll find something that sounds good for you.
Oh and for your information;
ICS > GB
and for GB firmwares, in order from newest to oldest, all 2.3.6 firmwares;
JW5>JW4>JVU>JW1
(those last two may be mixed up)
Most GB roms are on 2.3.6 now so it helps to know the above.
Thanks for the reply guys very much appteciated

I think Gamerzrom is still being developed but it has been moved to another forum. Technorumor blog.
If you want a list of ICS ROMS & Kernels check this thread out.

As mentioned there are plenty of threads out there asking about ROMS & for every ROM there are going to be people that tell you the one they are using is best. If you are going ICS there is a nice easy tutorial here.
It is for Team ICSSGS. It is an older ICS ROM but development has been slow lately so while it is still good it is running ICS 4.0.3 while the newer ROMS are all on ICS 4.0.4. Having said that it is still a great tutorial & rom to get you started. It goes right from all the files you need, to getting a stock rom in case things fail to flashing ICS. Once you done everything in this tutorial you will be in a good position to start flashing & testing roms to find the one you like.
Oh yes if we have helped hit thanks.
Root is essential if want access to the system of your phone(elusive folders).
Then u can tweak kernel(eg.voltage control or mc tweaker)and improve GPS(GPS aids) or backup your apps and settings with titanium backup.all these are apps u can download from android market.
These are good reasons to root your phone.
If u flash cf-root kernel u will have many options to tweak your phone,because it support init-d(all custom kernel's support this).like supercharger v6 or thunderbolt tweaks this will improve your phone greatly.but u need to READ a lot before going down this road.
Anyway good luck and don't be afraid to root.
ok i think i may have screwed up my phone i flashed the cf-root kernel and phone rebooted. it has now been stuck on the boot animation for an age( blue flashing android word) is there a way of getting it back to stock nejvb. please help this is my only mobile
sorted it thank god found threes firmware etc.
Glad it's sorted

Go to settings/about phone and check your build,then go to cf-root thread and find a kernel that matches your build and flash that.
But make sure that it's the i9000 thread and not the i9100.
There is a MOBILE ODIN,that is quite easy to operate. If u already got root u can flash almost anything.search for it, it's made by chainfire(cf-root, yep same guy)
But u need root to operate
time to do my rom
ok managed to flash my kernel with the cf-jvb kernel. what i would like to know now is "can i now just flash a rom, and could u explain what a modem is and do i need one or is it included in the rom" i am wanting to speed up my i9000 so could someone suggest a stable GB or ICS rom.
many thx in advance for all your help so far
I have just noticed that this new kernel will not allow Wi-Fi connection it will turn on, scan, wont find my connection and then turn its self off. Have I done something wrong or is it just the kernel that doesn't allow it?
Sent from my GT-I9000 using Tapatalk 2
According to your opening post. Your build is jvk not jvb. Jvb is your baseband. Which you change depending on where in the world you live, it will make your phone have a strong signal. For example my build is jw5 so I use a root made for jw5. I use kg3 as my baseband because it is the stock bell Canada modem and gives the best signal. Root with jvk not jvb. Gl

Hello
I own a French Galaxy S for more than a year, it's an unlocked unbranded one bought in Pixmania
Model number is I9000 and PCode is GT-I9000HKYXEF
Installed firmware is 2.3.3 updated officially by Kies one year ago
PDA: I9000XWJVH
PHONE: I9000XXJVO
CSC: I9000XEFJV2
It seems to be the latest version released for my phone in France (CSC XEF)
I have been checking samkiesupdates twitter page often but there hasn't been any update coming out which updates my phone to 2.3.4, 2.3.5 or 2.3.6 while other updates based in CSC OXA and DBT have already received the update (Seems OXA is the Open Europe version)
With this 2.3.3 version I'm having a few problems, such as a faulty GPS and a lack of free RAM. The gps problem doesn't seem to be a hardware problem (like the one with the GPS antenna in a few models) and I checked signals with GPS Test and it seems to be catching more or less the same number of satellites around the same signal level as other phones that have a working GPS.
So I would like to know a few things about rooting and flashing ROMs. I have thought of updating my phone to the 2.3.6 CSC OXA version
When flashing a phone, are protected phone contents affected like the /efs and folders that can only be accessed when rooting the phone?
What does rooting do exactly?, I know this is something like on UNIX systems where you need a super user account such as root to access system folders, but I only find threads about how to root the phone, but not what does it do exactly and what does it modify. However it seems, from what I read, that it is possible to return to stock (could Samsung Service Centers detect this modification?)
According to what I read, in case I flashed my phone with a custom ROM I would have to root my phone, why is this exactly needed? Why do stock ROMS seem to not need root at all?
Custom roms seem to already have different bootloaders. Is it possible to revert everything back to stock (including ROM and bootloader) just like if the phone was untouched in a way Samsung Service Centers could detect?
In case I flashed OXA 2.3.6, will Kies download new updates released for that version even if the PCode is XEF?
The PIT files, I know these are like partition size limits. Is there any advantage of using one or another?
I think this is enough for now. I have been having trouble finding information about these and it seems that all Samsung Galaxy S phones, even if they are the same model, won't receive the same updates for different countries/carriers. I bought an unbranded phone, and I should receive the same updates as other countries like UK do
You could use this guide for rooting your phone:

Thank you, however, there are lots of rooting guides out there and that's not my question exactly. My question is how doesit work internally and what does it do to the phone. Just to clearly know what I am doing to my phone at all.

- Being upgraded to 2.3.6 or whatever isnt really that great. A few changes were made, but really not much. Like some sgs devices have 2.3.4, mine came with 2.3.3 and you really cant tell the difference. here is a complete list of the changes if you want.
With this 2.3.3 version I'm having a few problems, such as a faulty GPS and a lack of free RAM. The gps problem doesn't seem to be a hardware problem (like the one with the GPS antenna in a few models) and I checked signals with GPS Test and it seems to be catching more or less the same number of satellites around the same signal level as other phones that have a working GPS.

So I would like to know a few things about rooting and flashing ROMs. I have thought of updating my phone to the 2.3.6 CSC OXA version
When flashing a phone, are protected phone contents affected like the /efs and folders that can only be accessed when rooting the phone?
- Folders like your /efs /data and /cache should never be touched. Only the system and kernel files are replaced. It is possible for /efs to go corrupted during a flash, HIGHLY unlikely using Odin though. But once your rooted, do a backup of the folder and keep it in many places.
What does rooting do exactly?, I know this is something like on UNIX systems where you need a super user account such as root to access system folders, but I only find threads about how to root the phone, but not what does it do exactly and what does it modify. However it seems, from what I read, that it is possible to return to stock (could Samsung Service Centers detect this modification?)
-I am to lazy to type how it works so go here. I learned off of that website. As for the other part, You can return to stock and never have samsung notice because we dont have a flash counter.

-Technically all roms use root. The difference here is that what you are referring to is the user having root acess. And of course Samsung doesnt really want uneducated people messing with the phones software, so it is locked away from the user. But the system still has to use it. But you do not have to have a custom rom rooted, but fact is that almost all are. For example I tried out a new jellybean port early on and it had no root access. The only thing in this case is that you must flash anything via odin instead of CWM.
Custom roms seem to already have different bootloaders. Is it possible to revert everything back to stock (including ROM and bootloader) just like if the phone was untouched in a way Samsung Service Centers could detect?
- I dont know where you heard this, but the bootloaders so not change on flashing a custom rom. Anyway, when you flash back to stock with odin, EVERYTHING goes. It will be 100% stock, not a single trace of you being rooted, having kernel and recoverys installed etc. Totally new.
In case I flashed OXA 2.3.6, will Kies download new updates released for that version even if the PCode is XEF?
- What sorry? I dont understand
The PIT files, I know these are like partition size limits. Is there any advantage of using one or another?
- Indeed, they tell odin how to partition your device. There is no advantage to either or. Read here.
I think this is enough for now. I have been having trouble finding information about these and it seems that all Samsung Galaxy S phones, even if they are the same model, won't receive the same updates for different countries/carriers.

Hello
Thank you very much.
I'm at work but I will read it again when I get home. It really helped, the rooting technical guide was pretty clear, and the PIT file information as well.
About the other questions:
With this 2.3.3 version I'm having a few problems, such as a faulty GPS and a lack of free RAM. The gps problem doesn't seem to be a hardware problem (like the one with the GPS antenna in a few models) and I checked signals with GPS Test and it seems to be catching more or less the same number of satellites around the same signal level as other phones that have a working GPS.

That's pretty interesting, I've seen options as Clear EFS in Odin that seem to be pretty dangerous at all since the EFS seems to contain specific phone data such as the IMEI
I understand these are partitions and not just folders. I remember getting into the recovery on my Galaxy S and formatting the cache partition. Does this cause any trouble at all?
/data partitions holds all the settings in the phone (according to the rooting guide formatting this partition causes a factory reset)
I will keep looking info on the forums for this to understand the details of these folders more in detail.
In case I flashed OXA 2.3.6, will Kies download new updates released for that version even if the PCode is XEF?
- What sorry? I dont understand
Click to expand...
Click to collapse
Well. I am not sure how Kies works but I remember reading that it only tries to apply updates if the PCode matches with the CSC of the ROM
In my case my PCode is GT-I9000HKYXEF and my ROM's CSC is XEF
If I flash the Open Europe 2.3.6 ROM, my CSC will be OXA, and in future updates Kies might report that it cannot update my device as I've read on some forums because my PCode doesn't match the ROM's CSC anymore.
All could be fixed by reinstalling the 2.3.3 XEF ROM image as well tho.
Few more questions
PIT repartitioning, does this only affects /dbdata and /system. Correct? No risk of messing up with /efs (as it seems to be the most critical partition in the device, is it?)
I am taking a look at Cyanogen's MOD 7.2 for Galaxy S
On their install instructions they ask you to download a kernel and clockwork mod recovery and then Heimdall
Where is the kernel stored after installing it? /system?
If so, just reflashing a new ROM (or the stock ROM again would get back to the official kernel, correct?
What's the [Dump] option in Odin? Haven't seen that anywhere
I have to read some more info about the bootloaders first before being able to ask more.
Thanks

-I very much so agree, i dont know why you would want to use that. But Odin is the official samsung flash tool, so i bet that samsung uses it in their repair centers for something.
I understand these are partitions and not just folders. I remember getting into the recovery on my Galaxy S and formatting the cache partition. Does this cause any trouble at all?
-Yes they are separate partitions
- This is not bad at all. Usually before i do nandroids in will do a /cache clear to make it smaller. I think it might actually be beneficial to clear it once and a while anyway. Sometimes i just clear it. Your phone will boot fine. Keep in mind that clearing cache does not clear the dalvik cache, as this is kept on /data and has to be cleared from the advanced menu. Also a word of caution, i wouldnt clear the dalvik while your phone is on, everything will force close. So just do it from recovery
/data partitions holds all the settings in the phone (according to the rooting guide formatting this partition causes a factory reset)
I will keep looking info on the forums for this to understand the details of these folders more in detail.
-What more details so you want? and yes whenever you perform a factory reset, the dalvik cache, /cache and /data partitions are cleared. But just wiping /data will be the same, but the cached reminants will still be there, which isnt an issue, its just wasted, thats all.
Well. I am not sure how Kies works but I remember reading that it only tries to apply updates if the PCode matches with the CSC of the ROM
In my case my PCode is GT-I9000HKYXEF and my ROM's CSC is XEF
If I flash the Open Europe 2.3.6 ROM, my CSC will be OXA, and in future updates Kies might report that it cannot update my device as I've read on some forums because my PCode doesn't match the ROM's CSC anymore.
All could be fixed by reinstalling the 2.3.3 XEF ROM image as well tho.
-Ah i get it, and yes you are correct. Even though there will never be another update for your device.
PIT repartitioning, does this only affects /dbdata and /system. Correct? No risk of messing up with /efs (as it seems to be the most critical partition in the device, is it?)
-Yes, i believe that the 10mb is transfered between the two. But when you install cyanogenmod 9, it gets rid of /dbdata. There should NEVER EVER EVER be a risk of messing with /efs. It is a rare occasion for it to go corrupt. Possible though, so do your backups.
- As for being the most important partition, it is hard to say. Your phone will boot with no /efs, it will just lag like hell, have no service or imei. Kinda hard to explain that one to the repair center since nothing touches that partition, ever.
I am taking a look at Cyanogen's MOD 7.2 for Galaxy S
On their install instructions they ask you to download a kernel and clockwork mod recovery and then Heimdall
Where is the kernel stored after installing it? /system?
If so, just reflashing a new ROM (or the stock ROM again would get back to the official kernel, correct?
-I believe that the kernel parts are mainly stores in /sys, although there are pieces in other places as well. (ex: /data/local/devil for devil kernel settings)
-Also, unlike my old galaxy gio, the recovery is packaged with the kernel on galaxy s. So changing the kernel replaces the recovery as well. You cant do it individually.
-Yes, all aftermarket and stock roms come packaged with a kernel. For example, i use devil kernel with my cm9. But when i flash a new version of cm9, it replaces the kernel and i have to flash devil kernel again.
What's the [Dump] option in Odin? Haven't seen that anywhere
-DONT take my word on this, i am not 100 sure. But i think dump, performs a dump of all the partitions to your computer. Not sure, so i dont advise trying it without research.
I have to read some more info about the bootloaders first before being able to ask more.
-Okay, let me know!

Hello
Thanks again
I guess ROMs like CM9 (this seems to be the one I am interested on) don't mess with PBL like boot.bin or the secondary bootloaders right? Or do they? (Only ClockWork Mod modifies the SBL to install it's own recovery I guess?)
Are all the needed folders on the stock ROMs as well? Like boot.bin, the secondary bootloaders and all the folders such as /dbdata /cache /data /dev /etc /lib /mnt and all these folders that are typical to see on UNIX and Linux installs?
As seen in here: http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S_Series#Partitions it seems they contain the PBL, SBL and folders like /mnt. So I guess they have everything on them ready to go
It's just to know which folders to backup in case it's needed.
Does ticking repartition with a PIT file in Heimdall or Odin repartition the whole device in a way where important files/folders get deleted (/efs for example) or does it just repartition /dbdata and /system without touching anything else on the device?
Does installing ROMs from Odin or Heimdall format the partitions before installing them? Seems CyanogenMod 9 has a script to turn partitions from RFS format to EXT4
What if I wanted to get back to stock, would Odin format them in RFS format as well?
I guess these are all the questions I need to ask to cover all doubts.
Thanks!

-Nothing unless otherwise stated messes with the bootloaders on most devices. But our bootloaders are unlocked, meaning the partitions arent signed and the bootloader doesnt check for sigantures, so it doesnt care if we have a custom recovery. When we use the three button combo, all it does is trigger the bootloader to boot into the recovery partition. But since they arent locked (bootloaders) and partitions arent signed the bootloader doesnt care whats there. Itll boot whatever is there. So no mods needed for custom recovery.
********NOTHING MESSES WITH BOOTLOADERS UNLESS OTHERWISE STATED ***********

- Yes everything you need to go **********100000000000000000000000000000000000000000000000000000% back to stock ************ is in there, even bootloaders. The primary bootloader isnt, cause nothing will ever touch it.

-The only thing you should backup is /efs
Does ticking repartition with a PIT file in Heimdall or Odin repartition the whole device in a way where important files/folders get deleted (/efs for example) or does it just repartition /dbdata and /system without touching anything else on the device?
-Odin only will repartition /data /cache /dbdata and /system back. Removing things like /datadata in the process.

Except unlock attempts

-This is a question i wish someone had answered for me when i was new here. Odin wont format the /data and /cache and dbdata(i think?) when flashing back to stock, so if you try to boot, you will bootloop. Only the stock recovery can format to rfs and knows how to handle it, so you must do a factory reset to format the rest of the partitions back to RFS.

Hello
Thanks again for your infinite knowledge
I think that's all. Anything else you suggest or something I should read? WIki is pretty good, but I think it's far from complete and more could be added
Samsung stopped genuinely supporting this phone quite a while ago. The burden of updating the device has fallen onto the development community. Given that the I9000 is one of the most popular Android phones, LOTS of development has taken place since then.
The kernel on this device is part of the boot image, on its own partition. Recovery is coupled to that partition.
Rooting a device adds a new binary (su) to the system partition. This file is given permission to run as user 0 (root) and acts as a proxy for other processes to perform privileged actions (deleting system files, mounting partitions, accessing all data, etc).
Most custom ROMs come pre rooted since rooting is quite popular. Titanium Backup is the exemplar for what an application can use root privilege for.
Installing a custom ROM does not require the stock ROM to be rooted, it requires a custom kernel (with a cwm or twrp based recovery).
Most high quality custom ROMs (read CyanogenMod) have scripts to protect the efs partition while flashing.
As long as you can get into download mode on your phone you can always get back to stock firmware. The service centre won't know the difference.
The bootloaders are provided by Samsung, these are not replaced by custom ROMs.
Personally I run a modified build of CM10 and use a radio from the Nexus S (KJ1). I'm very happy with the overall battery life of my phone, signal quality is good in Australia (can't say with certainty for any other part of the world) and performance is quite snappy.

One more question
What is baseband exactly? Is it related to modem/phone firmware?
I see it's never changed or replaced by installing custom ROMs

Baseband/modem (samething,)is the little piece of software that talks to the cellphone towers. And because each area uses a different frequency, there are many different ones.
Also good to note that it is not ATS all related to GPS or WiFi.

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.
