Ok, i have read many posts, the one from ODIN and ask people, watched videos, and nothing. Im starting in the rooting process, im currently on Phoenix 2.5, before i flashed this rom i made a backup rom with Clockwork, i decided to restore to stock using clockwork, but it failed on me and i fear that my phone was bricked. I flashed again the phoenix rom, but i want to return to my stock rom, but i dont know why, i just want to flash darkys rom, but i dont know how to restore back to stock, if i use odin by default i have to do the master clear, please help me, i dont want to be stuck on this rom.

#1: Are you disabling Lagfix before flashing? If not, that may be your problem.
#2: Prepare to be flamed for posting in the devs section with a Q&A post.

POST IN THE RIGHT SECTION (I guess I had to do that, right??)
To answer your question - Gr8danes is right, you should be disabling your lagfix to restore your backup first.
Do this by going into your /sdcard/voodoo directory - Create a folder named "disable-lagfix" and reboot your phone. You will hear the robotic voice reconverting your file system - this will take about 3-5 minutes.
Then proceed with flashing your stock backup.
If that fails, you will have to use ODIN One Click to revert back to Eclair 2.1

So as long as the file system is restored (voodoo disabled) you CAN nandroid back to stock? Awesome.
thanks a lot, and sorry for posting in the wrong section.
Suppose everything fails, when i decide to use ODIN, do i need to do the master clear?

no you do not need to master clear
also, the nandroid doesnt backup the KERNEL or the MODEM so you will likely get a bootloop after trying to restore your stock backup. in order to get back to stock, the best option is ODIN.
im using clockwork, i did the backup with clockwork

yeah, clockwork doesnt backup/restore the stock kernel+modem for you (one of its downfalls on this phone it seems). thats a manual process. the other option is to use the JH7 stock+rooted rom, thats designed for clockwork
But if i disable the lagfix, and do the restore using clockwork, it will fail? I MUST USE ODIN?? If i have to use ODIN, whats the point of doing a backup stock rom?

dont know of any links. i just know in my testing that is what happened.
if you look at a backup done in clockwork, there are the following files created:
cache.img
data.img
datadata.img
nandroid.md5
system.img
if you are flashing from a 2.2 rom to a 2.1 backup, you will get caught in a bootloop because you still have the kernel from 2.2, as cwm doesnt backup the kernel for our phones. if you flash a 2.1 kernel, via clockwork, or odin, your backup will boot up, but you will probably get FC's on a lot of things, because the modem is still a 2.2 modem, and causes instabilities. if you then flash a 2.1 modem, your backup will boot up without any issues. the best way to deal with this is to keep a 2.1 kernel and 2.1 modem CWM flashable zips on your sd card alongside your nandroid backup, flash the modem and kernel, then restore the backup.

It backs up apps and settings, but it isn't meant for restoring firmware versions.
If you just want to run Darky's then just flash it and skip the whole returning to stock step. It's really not necessary.

You should use the option in cwm recovery for WIPE DATA/SYSTEM RESTORE before you do, but yes.

Yes, u don't have to restore stock first before flashing another rom, but like said above, make sure to do a factory reset in cwm..
As for odin, you don't have to master clear either, you can use either odin one click or download a stock rom from samfirmware.com and use regular odin...

Here are the install instructions from the first post of the Darky's thread:
HOW TO FLASH
Place the ROM on the root of your SD card.
Backup your apps using Titanium Backup.
Open ROM Manager (Downloadable from the market)
Choose "Install ROM from SD card". If after you flash and you have problems like force closes and you can't receive calls, wipe data/cache.
Let the phone sit for 5-10 minutes after booting.
Be happy.

That's pretty much how I've done it with all the ROMs I've used for the last couple of months, except that I boot to recovery mode to choose the ROM and start the install.
ok, thanks a lot guys, i spent all my thanks for today, but the conclusion is that i can flash darkys rom on top of phoenix, restoring back to stock will be if i want to take it for warranty or something like that right?

That's my opinion. The install script formats and deletes everything anyway, so going back to stock is superfluous. Some people disagree, but as per my other post, the Darky's instructions say nothing about flashing stock.
I went a couple of months without going back to stock and in that time I flashed various versions of Cognition, Darky's, di11igaf, Assonance, Perception, Axura, Phoenix, Doc's, Serendipity and probably others I've forgotten. I only flashed stock the other day because I sent my phone back to Samsung to see if I can get one with working GPS.
I want to Flash Team ICSSGS [Android 4.0.3] (Link to ROM Thread) but I am not for sure what Bootloaders or Kernel I need to use.
I currently have:
Firmware Version: 2.2
Baseband Version: I897UCKB1
Kernel Version: 2.6.32.9
Build Number: FROYO.UCKB1
In general, the Gingerbread bootloaders are preferred with any of the ICS ROMs, because they are more ubiquitous and can be used with virtually any version 2.1 thru 4.0. Kernel-wise, the ICS ROMs come with a kernel, and your only other option is Glitch v14 beta right now...but mostly, you shouldn't need to worry about flashing anything beyond what's in the ROM itself right now.

So that ROM I listed in my OP comes with its own Kernel?
And is there a particular Bootloader I should use?
If there is, may you please link me to it?
Hey im currently running the ROM you are asking about. To answer your questions you have to be on the gingerbread bootloaders. You can flash those using odin, or since there is an official update out, use Kies mini to update your phone to gingerbread and that will flash the bootloaders for you.
About the kernel, the ROM you posted includes a kernel in the .zip and when you install the .zip it will flash the kernel for you. Its a fine kernel and works great so dont worry about changing it unless you have problems.
Here is the link on how to flash the bootloaders using Odin. Its not a hard process and pretty safe so let us know how you come out on the other side!

Now when I flash this bootloader you listed, will Froyo still boot or will I have to flash my ROM afterwards?
froyo will still boot. GB BL are backwards compatible and the ISCSGS script should allow it to flash over any ROM
Hi all.
as i can't post yet in a thread mentioned by mrnapolean1 (http://forum.xda-developers.com/showthread.php?t=1362092) I'll try to ask my question here, as it related to a question asked by this thread starter
so i have gingerbread 2.3.5, installed CornKernel_UCKK4_v603 and custom rom SimplyStock KK4 V1.0 , so if i wanted to switch Team ICSSGS [Android 4.0.3] should i do following?
1. wipe data /factory reset
2.wipe system
3.flash from recovery mode Android 4.0.3 zip?
I already have a backup made with Efs Pro as a tar file
anything else i need to do?
thank you so much in advance

Yes, Froyo will still boot. If this were a layer cake it would go something like bootloader, kernel, rom. So basically, your bootloader has nothing to do with your kernel or your rom but it is at the bottom layer of the boot process. It does effect which ROMs you can use though as gingerbread and ICS roms require GB bootloaders. So flash the bootloaders, you will still be on Froyo. Update to GB. Root GB. Place the ROM on your internal SD and then flash it. If you run into any problems check the common problems page found on the first page of the SGSICS ROM.

First, if you want to keep any of your apps or contacts backup those as well using Titanium Backup. Make sure to backup to the External SD card or make a copy of the backup somewhere other than the phones internal SD.
Second, you dont have to wipe data/factory reset before you flash. This is only if you have the problem of a bootloop when you try to install. I had this problem and when I did the wipe data afterward it fixed it immediately. So follow this:
1: Boot into CWM
2: install rom
IF you have an issue with a boot loop at this point
1: Get back into CWM using the button combination
2: Wipe data/Factory Rest and Wipe Cach

one more question, i understood about data/factory/cash, but dont i need to format system before flashing new rom? i thought its always better to do before new rom flashing?

I think this was true when flashing older roms. When I flashed that ROM I did not format system and it worked fine. Let me know if you have any problems when you flash.

IMHO the best way to go from gingerbread to ics 4.0 is to
- in the development section download stock kk4 without bootloaders, unless you dont have them http://forum.xda-developers.com/showthread.php?t=1300843
- then download a kernel of your choice probably cornkernal and put it on your internal sd card
- download ICS latest build and gapps and put them on your internal sd
- oneclick odin the stock kk4, let it boot up completely
- power off and install kernal via odin without aut reset
- boot into recovery, factory/data reset, clean cache, clear dalvik, install latest ics, then install gapps right after,
- reboot system and youre done.
IF you want to go back to your other rom the simplest way is to just kk4 fresh install, install kernal via odin, then isntall your rom.
I always keep all my contacts synced with gmail, and titanium backup any game data or app data i need, and reinstall apps through the market.
hope this helps

From my understanding if you are running an ICS rom you can upgrade without wipe if it's an update to the same family ROM. Otherwise, i would recommend performing a wipe first since you'll have remnants of the previous Rom installed still and have no way of knowing if any elements are interfering with your new install.
I use App Backup and Restore for my apps and SMS Backup and Restore for messages. Doing this means wiping isn't half as laborious as without at least these items backed up.
Maybe it's a bit overkill but i always backup what i need. Wipe, Install, Reboot. Let the phone do what it needs to. Reboot into recovery and factory / wipe / clear cache and fix permissions. I rarely get any problems this way.
Maybe this is helpful to you.
Thanks for sharing.
As per you above comments i can directly flash the ICS dark Knight rom from the current SGS RC4.2 rom by just flashing from the recovery mode?

ya you can.. but its always better to do a backup of your apps/ data and do a factory reset and then install a new rom through recovery.. a fresh install would prevent any problems... also in every rom's op the install instructions are given.. better to follow those as you'll be able to get better help in case of any problems..

When you restore a backup with cwm do you get all your apps back?
And what exactly does it restore?
The only time i tried the restore function was when i flashed ics but it was a gb backup and i got an error .so help me please
If u want to restore a gb. backup when on ics, u need to flash gb. Kernel. then u reboot directly into recovery(advanced/reboot recovery) and restore your backup.
And yes all your apps and settings will also be restored.
thank you..putting a gb kernel wont brake the phone?
No, bootloader on i9000 ics roms is ginger. And you don't have to wipe anything.
if u know witch ginger kernel u were running,flash that kernel and restore your backup
But DON'T boot up your phone. Just reboot into recovery from recovery and then restore your backup from the ginger kernel.

Can you backup custom roms? Because im having trouble.
Yesterday i updated from dark knight v3 rom to v5.5 and backed up the rom through recovery mode because rom manager wouldnt work (kept getting the android guy on its back with an exclamation mark)
I decided to go back to v3. I booted into recovery, wiped date/cache then restored my backup rom. When it finished, it stuck at the boot animation for 30 minutes. I pulled the battery and tried to boot into recovery but it just kept rebooting until i took my fingers off the up+power the proceeded to animatiin where it would just hang..... did i do something wrong?

Hi there,
I have a rooted N7000 running original Android v 2.3.6
I want to flash (test) it with a custom ROM.
I made a full backup of my current system (via CWM backup)
Now, when I flash a (new Android 4) custom ROM, will it then be possible to restore the old v2.3.6 image that I made, using CWM?
Other question: Do I need to take care of what type Kernal version I have
I have 2.6.35.7-N7000XXKKA-CL726566
Baseband-version is N7000XXkk5

nothing to worry about, that is what backup is intended to do.
the only thing you have to watch that you're on safe kernel like philZ when wiping data in stock ics or jb (read sticky threads)
example: if you are on philz kernel and runing ics or jb, when you restore your backup of gb, you restore your gb kernel, system, data etc, just like backing home

OK, Thanks for the reply. So if I understand correctly:
1. I make a backup of my current ROM (Image via CWM) and put it in a safe place.
2. I can flash any custom ROM, and test/play with them.
3. Afterwards I can put back my old ROM again via CWM restore.
4. Reboot, and I'm back in the old state.
Is this right?
Can I flash ROMs by using CWM also (using zip files) or do I need to flash, using Odin?
I actually do not understand your remark about philZ, can you explain a bit more about what that means.

Since you are going to try custom rom, you need not to worry about emmc brickbug, since they will be using a safe kernel..but double check before flashing...so, if you are on Stock ICS kernel, you should NOT wipe/factory reset..if you do, you will brick your phone..you can just go through couple of sticky threads to know abt emmc brickbug, if you are not aware of that..whatever the steps you have mentioned above are correct..but when you flash a custom rom, follow the instructions mentioned in the Custom rom OP...

I actually do not understand your remark about philZ, can you explain a bit more about what that means.
Thanks for your help so far

1. Yes, copy your /clockworkmod to your pc (just for double safety) dont cut it or move it, you need it on your internal sd card always, if you wanted to restore it again... and dont rename it (you will end up with message md5 missmatch!)
2. of course
3. Every new custom kernel like Philz kernel ( for ICS TW and JB TW) http://forum.xda-developers.com/showthread.php?t=1901191
or hydracore (not working on TW JB, but works on all other) http://forum.xda-developers.com/showthread.php?t=1749863
have built in CWM 6.x.x.x , You can recognize them by the gray background in CWM recovery. (there is no need to install independet CWM or something else, like you do on your stock GB kernel)
They are built in almost every custom rom, and these kernel are safe for wipe.
3.1 . So if you flashed new custom TW ics or jb, and after playing with them, you want back to your nandroid backup, just go boot in recovery (now you see a grey background CWM6) do all the wipes (in my experience the best way is: (advanced > wipe dalvik cache, go back > wipe cache, then wipe/data factory reset, then go into mounts and storage > format cache,system,data and preload , dont format emmc and sd card. go back into backup/restore > restore from (internal sd card or some other place depends on where you place your backup)
4. of course, when youo see a message backup complete, reboot it
