You don't have to downgrade your phone to 2.1 to root your phone. Downgrading to 2.2 would suffice.

My Stock firmware is 2.1

I'm new to this rom stuff guys i read around and still can't seem to find the answer...
since the Vibrant stock fw is 2.1-Update 1
DO i have to download a rom that's 2.1?
or can i just go to 2.2.1 or 2.2?
so your on 2.1update-1 thing?
and want to get a 2.2 or 2.2.1?
Just root your phone, get rom manager, flash clockwork recovery, then flash roms. there's guides on this, their stickied.
Find em' im on phone
what I'm trying to say is do i need to be on firmware 2.2 to run roms 2.2 etc.
No. Root/rom manager/clockwork/pick your rom/flash per devs instructions. Literally that simple and almost as fast as you reading this.
The rom will wipe and flash over any existing firmware you have no matter what.
Oh ok thanks <3!

[Q] Mini Pro ROM Update (rooted)

Hi
I have an rooted xperia x10 mini pro, i rooted it using superone click. i am currently using android 2.1 update 1, i have installed: SuperUser, Root check, AdFree, CPU Master (free), BusyBox, ASTRO, SuperBox, Titanium Back Up and Applanet.
I want to update my operating system to either Gingerbread or Iridum but things ive read about it say i need App2SD, but where i am running 2.1.1 i cannot install it as it is 2.2 and up...
anyway, what my point is can someone please post a very useful and detailed tutorial, text or video i dont mind i just want to update the android system!!!
thanks
from lewis
So you want to install a custom ROM? You don't need App2SD for that, just xRecovery. Since you said Gingerbread I'm assuming you mean [ROM] Cyanogen Gingerbread CM7 based on MiniCM/CM7v13 (v14.5). Just follow the instructions there.
To install xRecovery, follow the guide here: http://forum.xda-developers.com/showthread.php?t=878427
or just the flashtool.

[Q] about upgrading & downgrading

i haven't got the machine yet, i dont find the tutorials available are noob-friendly and something about upgrading & downgrading are not clearly mentioned, maybe it's just because i am a little bit retarded.
if im not mistaken to install custom froyo rom from the stock 2.1:
stock 2.1->root->recovery->install rom, right?
So how do i get back to stock 2.1?
Is it useful to backup stock 2.1 using the recovery?
When i want to get back to 2.1 from froyo can i just restore my backup through recovery or i need any flashtool?
PLease help me
I dont know why you moving to 2.1 ROM when you can get amazing future on custom rom.
But you if decided then search for stock ROM 2.1 in forum it will be in .zip format (I got once but forgot link) OR go to SE web site choose your device & follow instation process with the help of SE PC suite.
Hope this is useful.

Root my LG Optimus S LS670?

I have a To Root my LG Optimus S LS670, its a plain one.
Here's my information:
Model Number: LS670
Android Version: 2.3.3
Baseband Version: LS670MVJ_6150
How do I root it?
It's been upgraded by LG already to 2.3.3, and I can't find anyway to root it.
SuperOneClick, GingerBreak or this.
Luck!!
I have this phone and gingerbreak worked then the next week the phone updated and i cannot get it to root now.
hheeeelllppppppp!!
Yea I can't get this phone to root when it's been updated to the LS670MVJ baseband every root method I can find is for the older baseband versions

This thread should help, I had to downgrade to ZVH using stock recovery, then use the optiauto CLI tool to root and install Xionia CWMA recovery. Root, radio and gingerbread works, but radio flashed with a Froyo downgrade is not legacy compatible with ZVJ. It's worth noting that while CM7.2 or 9 can be flashed from Xionia, you shouldn't do this before having all necessary files/drivers from the froyo, gingerbread and cm9 images, and CM9 flashed LS670s cannot be activated on Sprint.

I cannot go into too much detail since I spent hours on it and forgot and renamed a lot of stuff.

Hey, so I just got an LS670 (LG Optimus S) from a friend to replace my current phone. Not sure how it will go since I have an old SERO account.
Anyways, I had some time off and would recommend to you update flashing your baseband to ZVH. Turn on usb debugging from the applications/development from settings and use stay awake option.Use Sons Of Korhal 1.0.1 to root it. Update to ZVJ using its appropriate update.zip. Then use OptiAuto (aka OptiAuto-sfx) if its the new enough version will allow you to root the zvj baseband. Some of these files are hard to find, took me 3 hours total in trial and error.
This page helped a lot: forums.androidcentral.com/lg-optimus-s-rooting-roms-hacks/119130-how-manual-rooting-ls670zvh-zvj-links-root-zvd-zv9.html
and this one: forums.androidcentral.com/lg-optimus-s-rooting-roms-hacks/131297-how-rooting-ls670zvd-zvh-100-automated-zvj-automated.html
optiauto for windows might be this one, you'll need it: mediafire.com/download/dsblck8764079q0/optiauto-sfx.exe
