First of all you need to have fastboot enabled on your phone. This is a special boot mode that is disabled by LG. To get it you have to flash your phone with a fastboot-enabled rom. After that, camera+power will put your phone into fastboot and you will be able to flash recovery.
If you're somewhere in Europe, here's the current Europe Open ROM with fastboot:

Okay thanks
And now the next stupid question :-/
On my HERO I flashed new ROMs using recovery
How do I flash a ROM on my LG ?

you can flash custom roms via fastboot or if the developer has made a recovery backup you can flash with that

After alot of googling, I found KDZ_FW_UPD
it got it to work

Boot loader is unlocked but i don't have root access Nexus One Running 2.3.3

hello everyone. i been a long time lurker of this site but never had the courage/motive to post. but i have an issue.
after much reading of how great rooting your phone can be. i too wanted to do it. so i looked n looked until i decided that id tryout CM7 cyanogen site
i believe i was able to unlock the bootloader/device. everytime i power up my phone regular start up starts with an unlocked lock at the bottom(like its supposed to right lol)
but here is as far as i get to go. i backed up my apps with astro file manager. then downloaded rom manager n as soon as i open it says "you must root your phone for ROM manager to function. superuser was not found at "/system/xbin/su". use goo search on ur computer to root your phone"
im stuck here because well im a noob and dont know why this is showing up. i was kinda hoping one of you guys could help me out here...

Taking straight from the wiki. Please read it before asking questions.
very generic explanation of steps needed to update a stock phone to custom ROM:
Download the ROM of your choice.
Copy the downloaded ROM image to the SD card
Root if you don't want to unlock bootloader (or just unlock bootloader).
Flash custom recovery image (if not done while rooting)
Turn off the phone
Turn on the phone while holding Volume Down
Select "BOOTLOADER" from the menu
Select "RECOVERY" from the menu
Select "Wipe"
Select "Wipe data / factory reset"
Select "Wipe Dalvik cache"
Return to main recovery menu
Select "Flash update.zip" or "Flash ZIP file"
Turn off verification, if such option is presented
Select your downloaded ROM image
Wait for the flash to finish successfully, if it didn't - do not continue!
Return to main recovery menu
Reboot the phone
You can follow a video walkthrough for this here: How to Flash a Custom ROM

To add to the post above, look at my signature and make sure you read and execute the relevant guide.

Just to clarify what the others are saying. You don't have root because you didn't root your phone.
You only unlocked the bootloader, which allows you to flash partitions through fastboot.

you havent rooted ,just unlocked bootloader

since you have a unlocked bootloader you can do fastboot flash..
get amon ra recovery and do fastboot flash recovery recovery.img
after you do that it should say sending flashing and done with no errors
from then reboot into recovery and do a nandroid of rom then do wipe and wipe and flash selected rom you want.. cm7 plus gapps after reboot and you haverom..
nexus one is ez to gainroot if you unlockboot loadder.. if you dont then it gets more complicated..

Unable to boot into recovery using "Acer Recovery" from market/playstore

Hello. After updating my A500 to the official ICS rom, I easily rooted my tablet succesfully by downloading a program found on this website:
http://forum.tegraowners.com/viewtopic.php?f=30&t=350
Then, I downloaded an app from the market/play store called "Acer Recovery" wich lets you flash CWM recovery (which is built in into the app). The app said it flashed the recovery succesfully. Now, when I press the "boot into recovery" button I get stuck in the Acer logo and on the top left corner it sais in red: Recovery Failed
I would like to flash custom roms. What am I doing wrong?
Many thanks...

Which version of Bootloader are you running? The recovery installer app should tell you when you start it.
Also, which version of Recovery did you try to install?

Thanks for helping me out.
-Bootloader Version: 0.03.12-ICS
I tried installing the two only recoveries avaliable wich are:
-ClockworkMod Recovery rev1.3.4 by thor2002ro
-Stock USA 1.141.07_COM_GEN1 recovery
After flashing any of the two I click on "Reboot into recovery", it reboots but gets stuck in Acer logo and on the top left corner says:
-Recovery verified failed

I have the same problem too and I still couldn't find a way out
Firmware Specs are same as yours
I wonder if there is a simple way out
Anyone can help ?
Thanks

Ok, both of you need to go to this thread and read over the info.
The reason why your recovery "might have failed" is probably because you didn't delete a certain file from your rom before you flashed your CWM. That is... "recovery.from.boot.p" in the system folder.
If you don't, every time you reboot your will lose your CWM.
Anyhow, read this thread. Everything you need is there.
http://forum.xda-developers.com/showthread.php?t=1622425
And if you;re going to install some ICS Customs in the future, I advise you install a patched unlocked bootloader.
EDIT: One more important thing. Before you folks go off flashing and everything, PLEASE... Get your UID number now, and write it down in a safe place (like the box your tablet came in . If you tab gets borked up, it's the only thing that'll save it.
MD

As MD stated be sure to read that thread , once down reading it, re-read it , I would try using that method first ,it helps you learn , but if you want to go to this thread and it will be a whole lot easier :http://forum.xda-developers.com/showthread.php?t=1675939
I always tell people in here read as much as you can , read through the Android section as well!

uahuuuuuuuuuuu !
What can I say ......Afterota is AMAZING!!!!
Made my day, not my day...my month!
It works like a charm and it's really easy to handle
Thanks thanks thanks !
Ramp

Thanks, I did it as well with AfterOta, what a great tool. I am already rooted in ICS and have public recovery working. I'd like to try some custom roms. Is there any other step I have to complete before flashing a new custom rom?
Thanks again for the help

I would advise making sure you have at least Version 3 or higher of the unlocked bootloader. Version 4 is better as you can change the boot image. Also, with version 4 (and higher) you can flash any future bootloaders through CWM.
Also, make a system (nand) recovery backup before you go flashing roms. This way you have something to go back to if the flash doesn't go right.

part of the original problem you had was the recovery you tried to flash was an earlier version which doesnt match ICS , You can get the beta copy of Acer Recovery ,but you'll have to search for it , it also has updated ICS recovery listed

[Q] Can't Enter Recovery Mode to do anything

Hi,
I need a little help as I am a complete noob and have just crash landed into the world of Rooted Roms.
I recently rooted my stock 4.0.3 ICS rom for my Iconia tab A500, using blackthund3r_ICS_Root_6.0. It worked brilliantly as far as I can tell. The Superuser function is there and I even deleted some of the annoying stock games that are on the stock ROM.
As the next step, I installed the Acer Recovery
However, I am interested in trying a leaner custom ROM in order to improve the performance of my tab, so I downloaded the Acer Recovery Installer from the Play store. I chose the Recovery version CWM rev1.7 by thor2002ro (for ICS Bootloader) and clicked on the install Recovery Image.
When I clicked on the Reboot into recovery mode because I wanted to back up my ROM and eventually install a leaner faster ROM, I got the following error message:
Booting recovery kernel image
Recovery verified failed ...
Anyone have any suggestions to help me out?
Thanks in advance for your help and putting up with my Noobish ways!!!!

sounds like your rooted correctly if u cud install the recovery file, but u should use thors cwm 1.7.3 to flash roms because it supports aroma installer which the newer roms use. did u get message from acer RI saying recovery installed?
u can find cwm 1.7.3 by thor here .
just put the zip from that link on ur sd card
if u can get into the recovery you installed.
choose install zip from sd in your cwm menus and select the zip.
let it finish then reboot.
viola! you have updated your recovery and shud be able to make the backup u need.
it is what i used.
if u cant get into recovery yet try turning off your tab
power it on and hold the volume down button.( the volume rocker side closest to the power button)
hold them to u see the white righting in the upper right corner of your acer screen
if u get in, update.
if u still cant get into recovery. try one of those other recoveries
try to install thors cwm 1.7.3 zip from there.
if u like i cud point u to some roms ive tried, since we have the same tab. happy to help.

Hi shadowmikeshadow;41918411
I will give it a go and tell you if it worked. Thanks for your advice. After all I could use all the help I can get. I am totally new and clueless to this whole rooting thing. I've only had my tablet for about 9 months and I got tired of all the lags and thought it was time to root and get rid of all the bloatware.
I really appreciate all the support you profis out there are offering. In general this whole site is GREAT!!!!!

np man im happy to help. well get u goin for sure

also couldnt hurt to double check your root with root checker(free app) could be making ur AcerRI not work correctly
and if u still cant get it to work and u are rooted correct theres still more we can do. its just more complex so try those first..

Do I have to do anything with this Recovery zip file that you suggested. I put it on my SD card and rebooted in Recovery mode and I still get the same error.
Please keep in mind I am complete Noob at this.
Thanks.

So if u can't get any recovery working install that zip via adb.
u can download this so u won't need android sdk.
follow all the instructions on the platformer page.
If everything went OK and adb sees your device
Follow this guide for adb here
but use the recovery from the zip in earlier reply.

Still desperate

Hi Everyone,
As of posting this original thread above I am still stuck in limbo. I have read, read, and read and am more confused then ever.
There are so many suggestions out there and I dont know what to do.
My problem is this: I have no way to enter the recovery mode to do anything (flash a new ROM or Stock)
If someone out there has the time and patience to help me and can talk me through step by step how to fix this problem, it would be highly appreciated.
Thanks for your understanding and support.

[Q] Flash new bootloader

Hi there
So, I can't enter recovery when I go into the bootloader to do so. I click 'recovery' and it just shows the black start up screen with the google logo. And nothing else happens. Ever. I reflashed recovery, and was able to get into recovery to install a new rom. However, after that one time, I was once again, unable to enter recovery. Now I haven't the time to be reflashing recovery just to get into it every time I want to, so I looked for a solution.
I did some reading around and apparently it's the bootloader version I'm using. (According to post five in this thread, and my assumption that I'm having a similar problem to this thread's OP.
Now if that is the solution to my problem as well, I need a bit of help. I can't find a file for the old bootloader, nor do I have any idea how to flash an old bootloader. (And please know, I wouldn't be asking had a google search not come up fruitless).
EDIT: Would flashing a completely stock 4.4.2 image update my bootloader? I wouldn't mind doing that, rooting that, and then just installing purity rom or something.

Hi Mate ,
I been looking for the same but for other reasons , to flash it is not too difficult for what i see in this thread tell how to do it manually:
http://forum.xda-developers.com/showthread.php?t=2150251
or
http://forum.xda-developers.com/showthread.php?t=2417097
in the first one they even have a zip version of it which should install like any other zip from recovery
Also you can use a tool kit like NRT which makes life a lot easier once you got the bootloader image...(advance utilities)
http://forum.xda-developers.com/showthread.php?t=1766475
My problem is that i do not know where can i get the different bootloader images...
To your question i think so , bootloader should be included in the factory image......downloading one to confirm.

If you download the factory image, extract it, the bootloader is in the folder. Then just flash through fastboot. Just make sure you download the correct bootloader for your device

For anyone reading this thread, my solution was too move to the 4.32 bootloader from JWR66V. I flashed the .img file from this thread using Wugfresh's fantastic toolkit. (linked to in the 2nd post of this thread).

I would recommend learning how to use adb and fastboot. Toolkits do not always work as expected and you will then need to use fastboot to fix it
