Hello all,
I was wondering can i change between a nandroid backup of an ICS install (say darknight) and a gingerbread nandroid backup.(say stock w/ rooted kernal)?
or do both nandroid backups need to be the same base?(ICS or GB)
Same base as nandroid required to restore.

U can. But u should flash to stock first. After that u can use restore frm backup.

ICS Roms run a different file system to Gingerbread Roms. As mentioned in the previous post if you wish to restore your backup you would need to first flash a stock rom then restore your backup over this.
The process is to use Odin with the 3 files (phone, pda, csc) and the 512 pit file. You will also need to have repartition checked.
You may also need to flash stock a second time using the 3 files. The 2nd time don't use the pit file and make sure repartition is unchecked.

I can't seem to find this topic buried somewhere in the forum.
Can I simply flash the JM8 2.1 stock rom from Froyo JPH I'm using now without running into problems? My need being these beta froyos can be unstable and too slow at times.and I read JM8 is stable.
What's the best way to go about it thanks guys

That is because there is no trouble flashing back to 2.1, just make sure that you backup the efs folder then flash back using 512.pit file repartitioning the file system. When done, boot into recovery mode, clear cache and do a factory restore and you are done.

This, did it this morning... didn't have a lagfix installed so dunno if that changes things.
I did the same thing as you, updated to JPH then wanting to go to JM8.
You can flash using Odin (follow instructions on JM8 thread). After the flash, you should get stuck in the bootup screen because the settings for 2.1 and 2.2 are different. You need to enter recovery mode and wipe your phone.
Thanks a lot guys I thought there would be more to it than that. I'm running stock JPH I don't think that a lagfix would make any difference to the downgrade. I'm not familiar with the efs folder though

hi,
i'm going to flash a custom ROM to my i896, i'm currently on stock ROM + speedmod k12t, have already disable lagfix, and backup all data.
i did researched, but what i want to know is not there.
i know i need to be on stock ROM to before flash, since i'm on stock rom, i still have some questions
so i got 2 questions:
1. do i need to flash back to restore kernel before flashing ROM?
2. after flashed ROM, do i need to flash the speedmod kernel aagain?
thank you.

1. no, you don't need to flash to the stock kernel;
2. usually the rom comes with certain version of kernel, you can definitely replace it if you want to use the latest speedmod, for example.
thank you so much.
i got another question
i use odin3 to flash ROM
i put the ROM file in the PDA section. leave phone and CSC blank.
but what should i put in PIT section?

usually i only use odin3 to flash to the stock rom. you need to put .pit file in the PIT and a tar file in PDA.
but since you are flashing to a custom rom, usually you can get the cwm file and use cwm to flash. it is easy and quick.
yes root phone grab rom manager from app market is easy as pie
grab files 2 flash put them in sd card by phone browser or with usb cable and pc, flash with rom mamanger is easy as 1 2 3
if any more help is needed ill c if i can find thread link tonight also there is a vids on Congnition 3.04 thread makes life easy sence your stock allready u can skip odin if u like but that is perfered way
When I flash new roms, I drop zip onto my sd then boot CWrecovery, then flash zip from clockwork recovery, without using rom manager. I had an issue restoring a nandroid backup i made using Rom manager (md5 sum issue?) and i couldn't restore the backup. I read somewhere this can happen from time to time. Rom Manager is good, you can rename your backups. Flashing roms gets addictive!!

About the md5 sum error, sometimes having spaces in your backup name will make it say that. Remove spaces and it should work again.

how do you unroot if you have used the following method to root your phone?
http://forum.xda-developers.com/showthread.php?t=788108
You flash a stock ROM with odin with pit file and repartition
Will that make me loose my settings and apps? also is the pit 512 and its the PDA file that I flash? thanks I am new to this!
Sent from my GT-I9000 using XDA App
Yes the repartition deletes everything - you should use titanium backup to backup your applications. You should download a stock rom with all the 3 files - phone, pda, csc and also mount a pit file. That's the price you have to pay to get a clean installation without root or anything that is not stock.
Thanks for the prompt reply! just one more thing since titanium backup requires root his would I restore the apps on a stock Rom that's not rooted? is that not supported? Planning.on a fresh flash and stay on stock but keep the apps I currently have. Thanks

My USB port is not working anymore, so I have to unroot using CWM or SGS kernel flasher. I have a stock rom for my phone, that has these three files:
CODE_I9000XWJVH_CL184813_REV03_user_low_ship.tar
GT-I9000-CSC-XENJV4.tar
MODEM_I9000XXJVO_REV_00_CL1003066.tar
I already flashed the CODE_I9000XWJVH_CL184813_REV03_user_low_ship.tar without problems, but the phone was still not unrooted. From above I understand that I have to flash all three files, but what is the role of the pit file, when using Odin (which I cann't )? Do I need the code that is inside, when unrooting without USB?
I've been asking for help after screwing up my Tab while trying to restore my Roto Backup with Odin, and the thread has been completely quiet.
I just wanted to ask an easier question, and see if that might tell me everything I need to know: Has anyone other than rotohammer ever actually successfully restored their Roto Backup? Second question, has anyone, including rotohammer, ever restored their Roto Backup with Odin?
The reason you screwed with your roto backup is the base in which you flashed the backup over and how you flashed the backup.
Here are the Reasons for Rotobackup failures:
1- Flashing a FROYO backup over a GINGERBREAD system (Both systems have DIFFERENT BOOTLOADERS) this causes lines and corrupted system image etc.
2. Not Flashing the correct PIT file or flashing one at all over a custom ROM you are using e.g Flashing your ROTO without PIT over overcome ROM formatted in EXT4 can result in a non boot as the kernel doesn't support EXT4.
3. Flashing bootloaders (boot.bin and SBL.bin) from the Roto backup. My advice: DO NOT DO THAT IF YOU DON'T WANT TO END WITH A HARD brick. For some reasons bootloaders from rotobackup arent really Safe.
My advice is to flash a Standard stock firmware (Froyo if you backup is froyo and GB if your backup is GB) then flash your Roto backup over it WITHOUT pit and WITHOUT bootloaders.

Thanks for the help. So you've managed to get your Roto Backup to work before?
So if I can't flash a bootloader from Roto backup, how do you recommend I flash back to the Froyo bootloader?
Also, any recommendations on a Froyo standard stock firmware image I can flash safely on an AT&T tab?
Well any stock package (froyo or GB) will have its bootloaders included so don't worry about them. As for a recommendation for a stock package yes actually I have 2 for froyo. JK5 and JJ4 packages should be good to go if you want to downgrade your tab to froyo (if you for some reason wanted to do that).

and
I'll explain
=-=-=-=-=-=
I got 2 Tab's same STOCK ROM's...
on one of them installed overcome...
then i took roto backup the other and restored with odin on the overcome..
wait wait... i restored a stock GB from samfirm first and then used my Froyo backup...
kinda the same like you explained not to do... and guess what?!
tab died needed jtag... after jtag they gave me back the tab with stock froyo from samfirm...
now i'll explain
=-=-=-=-=-=-==
i restored again my backup with odin and original rom is now installed perfectly.. i did had an error when it reached boot.bin though..
but i restarted the tab and it's up and running...
too bad i didn't saw your message before...
i just have a question..
so lets say i'm now in overcome.. want to install 2.2
you say that i'll should use lets say stock rom from samfirm
with odin... with p1 pit file
check repartition, areboot, freset and start...
when done restore using my backup created using RB
with odin... areboot, freset and start (pda with the tar file and no pit)
but in the 'tar' file not to include boot.bin and SBL.bin files? just those files?
sorry for bad english...
I would think that Roto Backup is only good for restoring within the same base rom. For example, if the backup is done under rom DXJDE, i would flash stock DXJPE rom with pit file and all, then follow by the backup without the pit file.
Secondly, if you want to revert to stock status, i think Roto Backup is only suitable for Froyo base. This is because in order to create a backup, your tab have to be rooted and with busy box. Froyo can easily go back to unroot status by using SuperOneClick.
Not so for Gingerbread. The only way to get unroot status is to flash stock.
Once you restore from your backup, your tab is rooted.
nevermind it's working...

So there's probably no way to go back to AT&T stock then once you flash a custom ROM right? Because there is no AT&T base ROM for the ROM that was originally flashed on my Tab floating around to use as a base for my Roto Backup.

I have a Roto Backup, made from my own tab right after I got it, just no stock AT&T ROM to use as a base.

That is correct. The backup made does not contain all the files.

I've done some research based on your recommendations. JK5 is actually no good I think, since it isn't a full ROM, and can't be used to re-partition.
JJ4, however, worked a charm. I downloaded it from samfirmware.com, and it came with all files necessary in the rar. Re-flashed pit, pda, modem and csc. Everything booted up as expected in Russian.
Then I used my Rotobackup, and re-flashed my pit and pda.
For the most part, everything is working, and restored, but for whatever reason, the boot animation is missing, and after the Galaxy Tab screen, it just turns black, and then after a while if I turn the screen off and on, I find it's already booted up (but booted with screen off). Any thoughts on why this occurs or how I can fix it?
My situation is that I'm increasingly beginning to suspect that my data connection is fritzy because of a hardware defect. I was on Overcome, and the data would just not be working when I turned on the Tab. The symptoms are one of the following: (1) data shows as connected and you can see the Tab sending but not receiving on the status bar, or (2) data shows as disconnected and then will show as connected for a moment and then show as disconnected again, or (3) data shows as disconnected, period. To fix any of these, I would have to either cycle the data or sometimes re-select the APN and reboot and then it would work. I then flashed to and used JPE for a few days, and observed today that my data showed as connected but would only send and not receive until I cycled the packet data setting.
Flashing back to stock, which I've now (mostly) done, is pretty much a last resort. I want to confirm whether this problem still exists on stock firmware, and if it does, I want to be in a condition to send in my Tab for repairs.
Just an update, I found this thread, which sounded a lot like my problem:
http://forum.xda-developers.com/showthread.php?t=899196
However, flashing jj4_bootloaders hasn't helped my missing logo problem. There is sound now, but still a black screen on bootup.
and none from samfirm are working? couldnt be.
Have you try booting up in recovery (power on, volume up combination) and do factory reset, clear cache?

hi there. i want to install 2.3.5 rom on my galaxy s and it contains a pit file in it. i wonder that if i use pit file , it fully wipes phone or not. i mean do i have to do a full wipe? and if i need how am i gonna do that?
Anybody correct me if I'm wrong but I thought Odin does a full wipe when its running? Don't take my word for as I may be wrong

Yes Odin do full wipe. You can backup you apks with titanium and the do the procedure with Odin.
