I was wondering if it's possible to go back to the official firmware via plugging the phone in to my PC with usb cable and starting the LG update? Will it allow me to reset the phone or will it brick it? I was planning to use Megatron until Froyo came along but my phone is beginning to act very unstable and I don't really wanna start with the flashing again.. Hoping for a simple solution
Thanks.
flash using kDZ to stock or go ahead flash CM7 by mik or 2.3 gingerbread by andy...And buy em a beer

hey
so i bought an optimus one this week and have already noticed the touch lag and stuff.
was always gonna root it, and have done jailbreaking on ipt/iphones but i know nothing about the android equivalent apart from what i have googled since then.
have read http://forum.xda-developers.com/showthread.php?t=901247 and a lot of other stuff and i thought i got it, but obviously i didnt.
basically, phone was on 2.2.2 so i downgraded to 10a 2.2 so i could root. ran z4root, installed custom recovery and then flashed milk_os's fixed kernel onto it.
kept showing "android.process.acore has stopped working" errors on screen, and i thought i could just upgrade back to 2.2.2 without breaking the kernel.
couldn't find a download of the latest firmware (but have since then) so i used pc suite 4 to update.
phone is back in 2.2.2 but root is gone and kernel is back how it was before.
tl;dr what i want to know is the difference between a rom and a kernel, and if it is possible to update the OS without changing the kernel, or root on 2.2 and then update to 2.2.2 without removing root so i can then install the milk_os kernel.
i have a copy of the latest update 2.2.2 from my provider which i can install with recovery if it will stop it overwriting kernel and/or removing root.
alternatively, cm7 is a 2.3.3 rom, is it worth just downgrading, rooting and flashing that? i assume that wont break my root
sorry for noobness, i just want to play angry birds without lag and im a compulsive fiddler/breaker.
PS also, if i go to 2.3 gingerbread am i correct in thinking my class2 microsd card will not work anymore on account of app2sd or whatever?
can someone please just tell me the best option for me, i have tried to google and read myself to find an answer but new to the scene and some things seem to be taken as understood and i don't get them at all.
thanks

a. kernal =/= rom
kernel is something that works beneth the operating system.. its like this
YOU -> Interface -> Operating System (ROM/Android/Linux/JVM) -> Kernel -> Hardware
and back.
I also assume LG's updater flashes both the rom and the kernel. so in simple terms, use Custom Rom to flash a new rom (void/CM7/etc) and use it. There is no trick way of the stuff ur explaining to happen.
b. Android 2.2.2 doesn't do jack ****. downgrade to 2.2 then upgrade to CM7 or whatever. class 2 sd cards SHOULD have a random unmount error. i think void might have fixed it; check plz. flashing cm7 should fix everything u explained, but don't expect much from the ROM; its in dev. FYI touchscreen fix is included in cm7
c. custom roms, including cm7 has root built in.
d. conclusion
i. use cm7 route -> flash custom recovery -> flash CM7 (tricky, be careful) -> touchscreen profit!
ii. use froyo rom route -> flash custom recovery -> flash rom of ur choice (void, megatron) -> flash touchscreen kernel -> reboot -> profit
e. press thanks if ur thankful. i would like some thanks lulz
cheers
There is a Kernel you can flash that helps fix the bug
http://forum.xda-developers.com/showthread.php?t=929941
thanks!!!
awesome, thanks heaps for that.
just one more thing, i assume the custom roms like cm7 and megatron/void all have root built in? or does the custom recovery do something to stop the root being removed when you reflash
once you root the phone, no matter what custom rom you use, it will still be "un-rooted".
Only when you use the kdz updater to put back original firmware, phone is no longer rooted.
thanks
awesome, thanks for that
Hello Everyone
I Have A An LG P509 And I Was Wondering If There Was A Rom With Swype Availible For This Phone Thats A Gingerbread Rom.
Also I Was Wondering If I Want To Unroot Later Will The Recovery Rom Have To Be The Same Firmware? For Ex (The Recovery Has To Be 2.3 If I Rooted It To That) And How Is It Possible For The Phone To Be Back To Its Original State When Unrooted?
I KNow I Asked 3 Questions (So Sorry For That) But These Things Been Rolling Around My Head For A While. If You Do Help I Thank You Greatly
1.no, u can get swype for free. Google for swype beta.
2.yes
3.yes unless u installed custom recovery.
Unrooting is not the same as flashing an original recovery firmware. I have not done this so this is just my imagination.
There are some posts for the original P509 recovery if you wanted to flash the LG firmware to return the phone to the original. You can also save the original recovery firmware before flashing a custom recovery. That uses the "dd" command to make an img file. I should have done that first. Look in the posts to find that exact command.
Unrooting is mostly just removing the Superuser app and "su" command and doesn't require reflashing, I imagine.
I don't know about the Swype for gingerbread.
Thanks For For The Help Guys But If It Has To Be The Same 2.3 (Gingerbread) Rom How Can I Return The Phone Back To The Original State When The Original State Is 2.2 (Froyo) Is There a rom i dont know about?

You will make a NAND backup before installing the new ROM. If you want to go back -> Restore backup.
Or you cand use KDZ update; it will install a fresh new factory ROM, your phone will be just like when you unboxed it.

Hi everyone, I've been using mik's cm7 for my LG P500. I would like to ask how can i revert back to original LG froyo. I know that upon flashing CM7, a backup using nandbackup should be saved but unfortunately I lost that backup and now its nowhere to be found. Someone help me please.Is it safe to go back to the stock rom?Please teach me or if anyone knows the link on how to do it please tell me...
Please help me oh Gods of androids

Q. How to get back to stock? I need to give my phone to warranty services how do I revert to official LG rom?
A. Check this thread. It is the v10b 2.2 stock rom as a flashable zip package. If you can't access the recovery, then see if the firmware for your country is available here or use this tool. Download the firmware and use the KDZ tool to flash. You will find instructions to use the KDZ tool on this thread. For a picture guide, check this thread.
Also for official GB lovers, see this. It is a v20g rom in flashable zip package. Or if you'd rather flash v20c/g roms from LGMDP, the links for that can be found in this thread.
If you are on the Optimus T, see this post. Uses the KDZ method.
If you are on the Optimus V, see [URL="http://forum.xda-developers.com/showthread.php?t=1025911]here[/URL].

use kdz updater (search xda)
or
use lgmdp (http://forum.xda-developers.com/showthread.php?p=19006040#post19006040)
or
if u like to use indian froyo (http://forum.xda-developers.com/showthread.php?t=1324105)
Many thanks to all of you guys. Another thing, is there any danger in reverting back from cm7 to stock rom? What I want to know is what will actually happen to my phone? will my Sd card be deleted?how about the applications? I have saved cm7 backup using nandbackup..would it still be available once I decided to return to cm7?
Sd card wont be deleted. You can copy your CM7 nand backup to your computer if you want. The nand backup rests on your sd card. Since your sdcard will be untouched, it will still be present after you revert to froyo.
Sorry for being such a nuisance and I know that I've been bugging you guys for a while..But Just one last question though. Currently Im using CM7, but when I try to flash franco's Kernel or Goldenleaf by fserve, I am encountering a very annoying problem.
1. When I lock my phone and try to unlock it by pressing the home or option button to bring out the unlocking screen,my phone seems to hang and stay in black screen where I have to wait approximately 5mins to get rid of the black screen and to gain access to the unlocking screen.
This is really annoying
black screen bug is a non problem and it has been fixed in the new version of goldenleaf and GBS
Thanks a lot..the goldenleaf i initially installed was the 111126 version.changed it to 111205 and i think everything is okay now
I have a loose USB port on my phone, making it very hard to get a reliable connection between the phone and a PC. It still charges, although it's usually very slow to charge as well. Problem is, I've got CM7 and clockworkmod recovery running. I have a backup of my stock ROM which I could go back to, but I don't think that's sufficient for warranty repair. Is there a way to do the necessary ODIN/heimdall steps via WiFi (for flashing the stock image), or on the phone itself via a terminal emulator? If it's something that increments the flash counter, I have a jig that works if I apply pressure to it correctly (for now...again, loose USB port), so I can reset that back after. If I understand correctly, I basically just need a way to flash the stock recovery, and possibly flash the kernel back to unrooted, without USB.
Any help is greatly appreciated.

You should flash back to your stock ROM backup first. Then, go on the market and download mobile Odin pro. With this app, you can flash kernels and stuff. Then you should download the stock kernel, and flash it to bring your phone back to Stock.
Sent from my SAMSUNG-SGH-I777
for a little more detail see this thread.
Thanks to the both of you. I've managed to get everything back to stock, and migrated to a replacement device. All that's left is to stick the phone with a bum USB port in the mail.

And do some more reading and searching before opening new threads.
I have tried on countless occasions to go from SlimICS to Cyan7.2, but everytime I do I soft-brick my phone :/
What do I have to do? Do I have flash some sort of GB Kernal beforehand? Link?
Thanks.
When you bought your phone did it had ICS pre installed ? If yes then u will never be able to use GB
It did, BUT.
I got it second hand, and it came with SlimICS.
The person I got it off quite it very soon after it came out - so I believe that it would have originally come with 2.3
I don't think what was said above was accurate anyways.
Try flashing a Samsung stock Gingerbread firmware (any, probably won't matter which one, as long as it is for your model phone) via download mode (using Odin or Heimdall) before attempting to flash CyanogenMod 7.2.
