I've been on custom ROMs so long, I've forgotten how to get back to AT&T official.
Do I just need the original .PKG file? Or will I need to get the original recovery.img? What about the amss and dsp files? Do these need to go back to original?
You'll need to flash the stock recovery and then update using update.pkg for whichever stock ROM you want. The AMSS and DSP files are part of the update.pkg file.

I've read many threads on how to change roms on the Streak.
I've actually managed to install several versions of Stephens ROMs.
I am however still confused on how to get back to a stock Froyo ROM. Why is it a two step process?
What is the relationship between fastboot and streakmod? I think this is the key. Once I understand this, then I will understand why I can't simply use streakmod to get back to stock.
Also, when you install a ROM shouldn't it completely erase everthing there and replace it? I don't understand why I get different results when I apply the same ROM depending on what ROM was applied before. This suggest that there is a preferred sequence when it comes to applying Stephen's latest ROMS.
Last question, how come doing a factory reset doesn't put me back in the state the device came in?

You need a stock recovery to install an update.pkg file (stock roms) and streakdroid recovery (or clockwork, but I suggest streakdroid) to install an update.zip. So you have to flash the stock recovery then install the stock ROM.

The reset restores that last installed ROM. This prevents updates being wiped out by a reset. It's intended to wipe the slate clean for the currently installed ROM.
Okay thanks. starting to make more sense.
I was able to download streak_318_12821_00.pkg file from Dell. I believe this is the Froyo 2.2 stock file from Dell for US versions.
so now i can use fastboot.exe to install this pkg file?

You don't use fastboot.exe to install ROMs.
If you are on a streakdroid rom you use fastboot to flash a stock recovery. This one should work.
You then rename the rom file to update.pkg, put it in the root of your sd card and boot into stock recovery. Select option2 and the stock rom should install. You will have to set up your phone after this (apps, accounts, etc.) so use your favorite backup solution first.
Okay maybe it's beginning to dawn on me.
So customs ROMS can only be installed via a custom ROM loader like streakmod. So once you update yourself to use streakmod, you can no longer install .pkg files which are the stock ROMS.
So now I have to flash the stock ROM installer back to the device to install the stock ROM which is a pkg file. Once it's installed, it replaces streakmod.
So once I'm back at the stock ROM installer and install the pkg file, I will have to reinstall streakmod to update to a Stephen ROM.
Do I have this correct?
Correct

Thanks a million. You helped me understand what a thousand posts across various websites and forums could not.
Not in retrospect it seems absurdly simple.
I've just managed to go back to stock and back to 1.81.
It finally all makes sense now.

slocko,
Glad you sorted it out.
Thanks to you too, for validating my thinking.

i'm on my KF1 stock rom, and i want to experiment on different roms.
1) are all custom roms (e.g lite'ning, cognition, darky) flashable using CWM? (i got my CWM from flashing the mirage kernel). or i can use odin anytime if i want to flash them thru the computer?
2) i searched for the forums for my stock rom, and i found a link:
http://www.multiupload.com/U95BI5QVDL
it's in an .exe format. is that flashable too thru CWM, or i have to use Odin to flash it back if ever i want to revert back to my stock rom? isn't flashble stuff in .tar or .md5 format?
The one you found is correct and it has to be extracted from .exe format via Winrar/7Zip. Then you will get .tar file which you could flash via Odin.
And I think you can flash any Custom ROM via Odin over any ROM.
Regards.
do i flash the stock rom under the PDA tab only, just like flashing a kernel? i don't have to tick any other options (bootloader, phone, csc, etc)?

Hi all, thanks for viewing this thread
- I flashed my friend's Bell SGS2 i9100M to CM9 a while back, but now he wants to go back to stock and needs to make use of his warranty because of the battery charging problem even when it's is not plugged in
- I need to flash his phone back to Bell stock firmware UGKG2, but I do not have the necessary firmware (PDA) .tar file to flash back to stock via Odin. I've checked Intratech's thread but multiupload is down so I cannot download the .tar files
- However, I have the stock ROM in .zip file, the kernel, modem and CSC in .tar file
- Unfortunately, I did not make the nandroid backup before flashing CM9 on his phone
- I currently do not have his phone with me, but he will be coming over in a few hours
So my questions are:
1) Is it okay to just flash the stock ROM .zip file via recovery from CM9? (After the standard procedures of wiping system, data, cache, etc.)
2) Will the CM9 kernel recovery flash the stock ROM .zip file? I think it might give some e: (some sdcard) error, I'm guessing... If so, will flashing a custom Gingerbread kernel then flashing the stock ROM .zip file via CWM work?
3) If 1 & 2 don't work, does this mean I absolutely have to flash back to stock via Odin?
I've also got an usb jig prepared
Thanks in advance

Hey,
like u said, the .zip includes .tar files.
.tar files always must flashed via odin!
Only way to to it via phone is using odin on phone, but I'm not up to date how is the status and if it's really working.
So to be sure:
1) make a full wipe (like u said above with formatting system, cache etc.)
2) Put files in Odin and flash
3) Flash cf-root or kernel to get CWM back (if u want)

the .zip file does not have the .tar files, it is CWM flashable; it has the META-INF folder, system folder, zimage, etc.

Oh ok. Didn't read carefully, sorry.
So dunno where u got it from, but if it is a source u trust, it should work.
... should be like flashin CM or any custom Rom
Much success!

I'm trying to revert my I9100M back to stock, however, Im not sure where I find the stock ics kernel for bell. I downloaded the bell firmware from sammobile, however i want to have everything correct before i do flash it.
With the bell firmware that you get from sam mobile, where do you find the PDA/PHONE/CSC files? and also, when i do find all three correct ones, where do i go to flash the kernel to the corresponding one? I don't want to brick my phone!
what format was it downloaded. if it is tar format, use odin and put it in pda section, it is an all in one file with everything you need bundled together.
if it is in zip format use cwm to flash.
if it is in another format, extract thyebfiles and then use either odin cwm to flash depending on the file ending.
