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?

As with the people that had the white line problem, with the corrupted graphics on the bootloader, I can't see recovery, just a black screen.

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.

Hi! I'm planning to install custom rom on my sgs gt-i9000 by Darky (either 9.5 or 10 RC).
But Darky uses DarkCore as kernel, and I want to use speedmod kernel (as I understood this one of the best kernels out there).
What is the right process to install this?
Flash the kernel via odin (PDA right?) the use Darky's Rom Configuration with "Skip Kernel" and then use recovry to install the ROM?
Also can I stay with my current modem which is I9000XXJPY? I really afaird to flash the modem (and CSC).
One last question is how to backup my current kernel/modem/csc/rom?
Also as I understood I need to backup /efs right? Is there something else I need to backup (my contacts are saved on the sim card so I dont mind loosing those and I dont mind loosing my current applications and their settings).
Thanks a lot!
if you are not rooted, get rooted !!
download CF-Root, or speedmod kernel, flash it through ODIN and make a full nandroid backup. Also backup efs just in case your IMEI gets corrupted.
i have used speedmod kernel with older versions of darkys roms, but voodoo kernel is recommended.. But you can try which ever kernel you like, providing you know how to fix if something goes wrong.
you can skip modem in the darky app if you are happy with your current modem.
and once you install cf-root or speedmod you will be rooted, so download 'titanium backup' from the market and that will back up all your apps
1 last thing, i cannot emphasise this enough.. be sure you know how to fix a bricked phone before going ahead with the flash. i myself - along with many others - have had 'issues' with darkys roms.... I am not saying you will, but be careful and always have a current backup !!
DarkCore is based on Voodoo kernel right?

if you ever get stuck in a bootloop, boot into recovery do a factory reset.
if you have serious issues, boot into recovery, do a factory reset along with formatting, cache / data / system, then re flash.
if you have even more serious issues, then you need to boot into download mode and flash a 3 file stock rom with 512 pit and re-partition checked.
thats all there is to fixing a bricked phone. Always make sure 3 button combo works before taking on any sort of flashing.
Thanks a lot!!
Hi all,
I don't know if this is the right place where to ask for.
I searched through the forum but, maybe for my poor english, I didn't find anything.
I've unbricked my SGS with the Darky's resurrection version. After doing this, i noticed that apps installed from Market disappeared at every reboot.
Trying to resolve this issue, I did a re-install of the resurrection.zip.
Now, I can't install anything. The only result is crash of the system.
My question is: how can I take the phone to a full clean state, in order to do a full clean rom install?
Thanks in advance.
download mode still works yea ??
flash stock eclair 2.2 in all 3 files (phone, modem, csc) and add 512 pit, tick re-partition and that should sort you out

Yes, download mode is still operating. The whole system is full operating, except for apk installation (....) .
So you suggest to revert to a stock Froyo (2.2), then use the standard procedure for rom flashing?
Doesn't this compromise my 2e recovery?
its the safest way, you can always re flash kernel to get CWM recovery back.
guaranteed to fix you up
having a wierd problem, as the title says i am unalbe to change roms and have it boot.ever since i flashed the ROGERS 2.3.3 (containing i896 ROGERS bootloaders)
no big surprise i didnt like it.
while reading this keep in mind i have alot of experience flashing, and yes lagfix was disabled!
odin flashed a CWM kernel (one was using before rogers)
restored Nandroid. (of before ROGERS)
stuck at kernel screen
Flashed different kernel compatible with rom.
stuck at kernel screen
Loaded CWM to flash a custom rom.zip
flashed OK
reboot stuck at kernel screen
Odin flashed i9000 gingerbread (with i9000 GB bootloaders) from few months ago
stuck at kernel
Odin flashed ROGERS 2.1 eclair stock.
stuck at kernel
Odin flashed ATT one click
SUCCESS!!
Odin flahsed Rogers 2.1 eclair
SUCCESS!!
ODIN flashed i897 ATT GB bootloaders
ODIN flashed CWM kernel CWM flash ROM
Restore NANDROID
SUCCESS!!
finally back to normal...**never flashing rogers 2,3,3 again!
or so i thought.
got bored and went to flash a different ROM
STUCK AT KERNEL
had to repeat all above steps!! ALL before it was back to *normal* again
any thoughts to what got permanently messed up????
Did you try reformatting system and cache before flashing a new ROM in cwm? (i'm just guessing here)
yes and the Odin one click re-partitions - wiping everything known.but still the problem exists after flashing my 1st custom rom i am unable to boot into a second ANY rom (stock or custom)
and this is VERY frustrating as i just finnished my own custom ROM and am unable to quickly flash test versions.!!
I don't know. Odin one click should have fixed everything. Did you master clear/reformat the internal Sd?
no not the internal sd.
also i remembered at one point right after being on ROGERS stock 2.3.3
the first rom i tried flashing was a custom build I made with a kitchen tool using cygwin.
anyways after flashing and failing, i noticed the update script i created flashed the zimage to 2 different dev/bml blocks!! one i never seen before.
i stopped using that kitchen tool but is it possible it flashed something to a dev block that odin one click isnt clearing? but it repartitions. that should clear EVERYTHING!
still my problem presists...
flashing issues. cracked screen. might be time to buy a new phone.....
You could use Heimdall to dump your partitions and find out.

Well, first of all the short history of my i9000:
Came with froyo, upgrade it by Kies to Gingerbread, rooted, flashed in CM7, flashed SGSICS.
Kay so, now i want to go back beacuse SGSICS is a bit sloooow. But it seems like if i flash by CWM it will brick because of the bootloaders.
Question
With the ICS bootloader, can I go to other ICS ROMs? (maybe its obvious)
If I want to go back I'll have to use ODIN (heimdall opens and instantly closes to me). I already have a I9000XXJPU Froyo ROM, but I'm not sure about the steps I have to do for a successful flash (can anyone tell me?). Finally, is it more dangerous to go back because of the bootloader?
Advanced thanks!!!
u can flash i9000xxjpu with odin before that u must backup ur efs folder
but

And could anyone answer my other questions?
