[Q] How do you downgrade back to 2.1 - Vibrant Q&A, Help & Troubleshooting

I currently have 2.2 Froyo installed on my Vibrant, and I want to get back to 2.1before I install Axura204. I tried installing Axura with OCLF and Rom Manager...but no luck, so I figure I might have better luck installing it if I went back to 2.1. Is it even possible to switch to Axura since I am currently using 2.2?
I've only been using an Android for about a week, so please dummy it down for me. If I have to flash something or use Odin, can you please give me step by step instructions?
Quick unrelated questions:
How do you disable One-Click Lag Fix (I tried using the disable-lagfix file, but I think it is still active)?
What is the difference between a kernel and a rom?

Click the icon in your drawer for OCLF and uninstall for there. Pm me for help with your flashing.

I would say just flash with odin and go from there. Do u known how to use it?

How EXACTLY do you flash back to 2.1? What files do I need to do it, and does it work with my existing firmware?
Sent from my SGH-T959 using XDA App

To flash to a 2.1 rom, make sure the rom has a 2.1 kernal comes pre flashed. For example, any bionix 2.1 roms can be used.

first time using ODIN need some help

greetings all, my phone setup is in my signature. i am running eugene's latest Franken-TWIZ rom using baseband JI6 and JAC's 1.1 OC/UV kernel . I have set up my phone for use with odin with the proper drivers and plan on flashing back to stock in a month or so before the Froyo OTA.
my question is, can i simply run odin and flash it back to stock using this guide link posted from the bible directory?:
http://forum.xda-developers.com/showthread.php?t=734475
i wanna make sure if this method is safe considering my kernel and baseband have been modified using Eugene's latest rom.
I am no expert but I flashed back to stock rom from ji5 which had a different kernel and all went well.
Yes it's safe. You are essentially erasing all data on your phone and returning it to stock so it doesn't really matter what base band, kernel, or rom you are currently using. However, unless you want extra steps in the restore, if you are using voodoo, disable it before you do anything!

[Q] Flashing New Roms

so, this may be answered somewhere else. but i couldnt really find a straight answer. i have bionix fusion flashed right now, so if i want to flash another rom, can i just flash it with bionix still installed? or should i reflash to stock then flash a new rom? sorry if this was confusing, just trying to get straight answer.
You can do either, most customs roms do a wipe for you automatically so it's like a fresh install. Just remember to disable any lag fix you have running

No. you must start from fresh (stock). Odin back to JFD then root then install the rom. If you have voodoo installed, always disable it before you flash anything.

I have flashed many times over custom roms, you don't need to go to stock unless you are going from a 2.2 to a 2.1 rom
Sent from my SGH-T959 using XDA App
but to avoid future errors it's always a good habit to start from stock, especially if you're from bionix for instance and would like to install froyo. That huge modification requires a start from stock in order to avoid future errors. if it's minimal flashing then you can just flash without going to stock.

I would agree with that

That's not true. You can do a straight flash over another rom. However, after you flash 4 or 5 roms over and over, it is good on occasion to flash to stock rom. I must have flashed every single Sombionix and Eugene rom available and only flashed to stock before flashing one of their roms once or twice.
Honestly if you flash to stock rom everytime, then flash a custom rom, you're really doing extra work for nothing as a few posts up had stated " most custom roms wipe everything anyways"; so just flashing back to stock, then flashing a custom rom is kinda pointless.
Moved to Q&A as not development.

I was just about to ask the same question. Thanks to all for this thread.

froyo and OCLF

Hey guys, running 2.1 and Ryan's OCLF.. Patiently waiting for Froyo.. Question is, I know I should remove the OCLF and unroot the device..
- Once its removed from the phone, can I just do the OTA update or thru kies and hop on to froyo? Or should I do a reset of the phone?
-Once I do have froyo, is it necessary to have the OCLF mod back on? Is it even possible to OCLF a froyo?
Thanks for any help
You can uninstall and reinstall rooting and OCLF all you want. Just make sure you don't have OCLF installed when doing the OTA Froyo update. But why wait? Just flash to a leaked Froyo like I did. And you can reinstall the OCLF with Froyo once you do. Anymore question pm me! Enjoy!

Yeah flash Axura I was scared of doing it week ago but I did it yesterday and I will never look back.
The official froyo probably wont be as good as the custom ones anyways haha

[Q] Vibrant Odin 2.2 stock files?

Maybe I'm an idiot and missed it somewhere or maybe it doesn't exist, but I'm looking for the stock Vibrant Odin files for 2.2. I have to ones for 2.1, but I hate having to use Kies to bring it back to 2.2. Any help would be appreciated.
What I use is Eugene's 2.2 Froyo ODIN which can be found here:
http://forum.xda-developers.com/showthread.php?t=833024&page=49
It will also automatically root.
The link is gone from that thread. Anywhere else I can find it at?

Try Whitehawkx's stock froyo rom (deodexed and Odin versions):

Hopefully, the links still work.
Just out of curiosity, why are you trying to go to stock 2.2?

Thats the best place to flash most roms from isn't it? I am on my 3rd and my wife is on her 2nd and we both have vibrants. Thanks for the link.
