Flashing Back to Stock ROM using Heimdall

---

I am having THE hardest time flashing back to stock rom using heimdall. I dont know how to use it, unfortunately i cannot use Odin..if anyone could instruct me on a step to step guide to getting this done, that would be great. i cannot seem to find one after looking for a good hour and a half :/ i got to samfirmware.com but once i download it asks me for a password and i input it (the one it shows to input) and it doesnt work.

Thank you

Just wondering, why can't you use Odin?

something like this

$ heimdall flash --factoryfs factoryfs.rfs --cache cache.rfs ..... --kernel zImage

just type "heimdall" and it will print the usage format. you can flash whatever you want.

Tell us what OS you are using. Do you have the most current version of Heimdal?
Also, try unzipping the firmware with a different tool.(what are you using)?

The reason I cannot use odin is because I have a mac and odin is not mac compatible. I am using precision v3.5. Firmware 2.2.1 I've used the normal text editor and zipeg. And I have the most recent heimdall

so since you are already on a 2.2 rom we will hope you are not having the mac sbl.bin problems.

steps are:
1 grab the stock firmware from here if you want froyo
http://forum.xda-developers.com/showthread.php?t=963403
or find the equivalent eclair version in the forums or on the samsung firmwares site.

2 unpack the archive

3 unpack it again so you just have the various files in a folder. there are 4 important files in the froyo linked above and one .dll you can ignore.

4 put your phone in download mode

5 put the 4 file in the proper slots (see attached image)

6 hit start.. wait...

If Heimdall cannot see your phone you might be having the sbl problem. head over to the main heimdall support thread and search around... ther are quite a few mac users over there

Has anyone sucessfully been able to flash Samsung stock 2.2 using Heimdall?

For some reason when it's flashing factoryfs it fails at 43% "failed sending data packet"

I have downloaded KB1 from here http://forum.xda-developers.com/showthread.php?t=963403

And tried the .zip file that Kies downloads during it's upgrade process, both do the same thing.

Ultimately I'd like to find a universal flashing method to be able to restore my phone back to stock. While also being able to flash Clockwork kernels for rebuilding CM7.

The only way I've been able to get CM7 to load successfully is to Odin1Click back to JF6 then use Kies (which requires a different USB driver) to get 2.2 loaded.

Then install USB driver for Heimdall, to flash a Clockwork kernel for CM7 load.
If something goes sideways this process starts all over again.

Reinstalling USB drivers over and over again is getting rather tedious.

Would really like to find out why Heimdall is failing when flashing factoryfs.

why would you upgrade to 2.2 to get to CM7??? you can go to CM7 straight from 2.1 JF6

Bootloader question?

I made a post recently asking "What's the diff between 2.1 and 2.2 bootloaders?"

Nobody knows (or few cared to share their knowledge with the group). The best answer I got was, (paraphrased) 'none?'

Just above step one: "This guide assumes the Samsung Galaxy S already has Android 2.2 already installed on it."
