You will have to have to follow these steps to get NVflash a recovery. http://forum.xda-developers.com/showthread.php?t=1056847 Then you can flash this from recovery. http://forum.xda-developers.com/showthread.php?t=1048274 to go back to froyo. If you only want to go to froyo to get root you can follow the first link and NVflash recovery then flash one of the pre rooted roms in the development thread. If you want the pure stock vanilla then you can flash the stock recovery by following the same quide as the first link I posted.

I cant make it work :/
i did everything it says on the thread you send me, and it doesnt work i cant go back to froyo. :S
I think i just broke the phone =( it stays in blank rebooting it self F!(#(&!$#&($13 the screen is black with the light blinkin =( what can i do????

I then flashed to 2.2 froyo, then tried to go back down to 2.1.. forgot to flash kernel and then had to use Odin 1.3 to revert back to stock. used odin with T959UVJI6... now how do i reroot my phone? it doesnt have the update.zip anymore, and i really dont think its rooted... whats the best way to root this guy now that i have i used odin to flash back to a almost, if not completely stock rom? i have tried my original method of superoneclick to which now doesnt seem to work...

Stock 2.2 ti custom 2.2 help

Told a friend I would update his phone for him since im already on custom rom. but im a bit confused.
Whats the steps?
Is step one to root phone, odin red recovery, or odin 2.2 rom?
update
If a mod could maybe delete or lock this thread it would be cool
Had a memory laps I figured it out thanks

[Q] So I went back to stock on my phone

because I wanted to try out a gingerbread rom and i figured that since I was at stock I would open up Kies to see what kind of update it would say for the phone, but when I looked at it, Kies doesnt show anything. I mean it reads and finds my phone no problem but where it shows "Current Firmware Version" its just empty.
I remember previous times I did it, it would still show Version 2.1 and ask me if i wanted to update to 2.2.
So I guess im asking, if I should be concerned with this?
I did use Odin to go back to 2.1 btw
which odin?
odin3 one click? the ATT one? the one that obviously wouldnt work with Rogers keis?
or odin3 flashing utility with the Rogers Stock roms in my sig?
keis is crap anyway. if you want 2.2 flash my 2.2 stock. but dont bother if you are going to flash gingerbread. avoid 3e recovery, but theres a fix for that too in my sig.

Actually it was yours in your sig. It was the only one I have been using since I found it at like the beginning of the year. You are right Kies is crap but I keep it because id like to give Gingerbread stock a shot once it comes out before flashing to gingerbread roms. But now that I think about it, I think it might be that kies had an update when i opened it since its been so long from the last time i used it. So it was probably that.
And thanks I will look at that 3e recovery before i start flashing.

[Q] downgrade from 2.3.4 to 2.3.3

Hi, I am an i9000 user. I upgraded my phone to 2.3.4 and rooted it. I want to unroot it. I also want to know how to go back to 2.3.3
Just flash it with ODIN
it is easy but you need to read about how to use Odin if you have not before, do that throughly.
Once you are familiar.
Get the correct 2.3.3 firmware you want from samfirmware dot com (you need to register free)
Make absolutley sure it is the correct firmware and read the how to guide on the site.
Flash it and that is that (you do not need to unroot before, the new firmware will be unrooted). Do not forget to back up all your data first as flashing wipes all out.
QUESTION but why on earth do you want to go from the better 2.3.4 to the bugy 2.3.3 ? (that is why it was released in May to be replaced by 2.3.4 in June) !!!!
why?
was wondering the same thing...im trying go upgrade...why go
back down?

[Q] Colorful screen bootloop

Have a t959V SGS4G with Froyo. I rooted it, and unlocked it. I then attempted to flash AntonX's "Basic with a Twist SGS4G KJ6 1.1.3" kernel using the SGS Flash tool. It seems that this Kernel is a Gingerbread Kernel, which I flashed on a Froyo system.
When it rebooted after that flash, the screen became multicolored, almost like static and gibberish, and is not boot looping. It wont get past the initial Galaxy S 4G splash screen. I tried the multiple means of accessing download mode with no success. I did just order a jig, but that wont be here for a few days.
Prior to flashing the new kernel, I did backup the old kernel, so its on the SD card.
Any thoughts on how to recover?
Many thanks!!
Use the guide in the second link of my signature and flash with bootloaders. You do not have GB bootloaders which is the reason for the rainbow screen.
rainbow screen - bootloaders

ks for your reply. That guide is impressive. i can see a lot of work was put intot hat. It looks like I would take this option:
2.This guide can be used if you flashed a ROM made for a different model phone (i.e. Vibrant):
----> Follow Directions for Flashing WITH BOOTLOADERS
However, I didnt flash the whole ROM. Just the kernel. So, I have aapparantly a Gingerbread based Kernel with a Froyo Rom. In this case, do I want to go to a FROYO kernel, or go to a Gingerbread (or a JB??) ROM?
I have the ultimate goal of going to a JB ROM. I'm starting to think I cant just flash the JB ROM over the Froyo, or can I? I'll have to peruse the forums a bit to learn more about that.
Finally - I cant seem to access download mode via any of the methods presented. I ordered a jig, so when that arrives, I'll follow the guide and either downgrade the kernel or upgrade the ROM.
This devide seems a bit more complicated to work with than the Nexus S that I was previously toying with.
Thanks for your input and assistance.
What are you doing?! Stahp!
You are still in Froyo? Why not migrate to Gingerbread?
By the way we only have ICS, for now.

You will need to follow the complete guide including flashing bootloaders if you want to upgrade to GB or ICS. No you cannot flash GB or ICS from Froyo recovery because of the bootloaders. As mentioned above, we do not have JB. If you want to flash back to froyo there is a KD1 One-Click FB put together. Let me know if you want to stay on Froyo for some reason and I will find the link for you.

Many thanks. I dont want to stay on Froyo. I'm helping a friend with this device, and she had never updated from Froyo. I'll take a look at moving into Slim ICS, since theres no JB for this device, unless anybody has any better suggestions.
This whole problem started for me after I realized that to get ROM Manager working on this phone, I had to go to a different Kernel. I didnt realize that the kernel I picked had the wrong boot loaders, and Voila. A rather unattractive rainbow screen. As soon as I can get into download mode, I'll jump on this.
I thank everyone again for their input.

ROM Manager does not work for this device and can cause issues.
