Hi All! After huge search in the forum i found the guides scattered ,so i decided to put it in 1 thread helping all the newbies to install custom rom.
PROCEDURE INVOLVED​​
1.DOWNGRADING YOUR PHONE TO 2.2
2.ROOTING THE PHONE
3.CUSTOM RECOVERY
4.A2SD SUPPORT (NOT MANDATORY)
5.FINALLY INSTALLING CUSTOM ROM​
I WILL GUIDE YOU THROUGH ALL THE PROCESS IN DETAIL
GREAT NEWS : NO NEED DOWNGRADING JUST USE THE APK IN THE LINK AND ROOTING IS DONE IN ANDROID 2.2.1 AND LATER STILL I AM KEEPING THE DOWNGRADING DETAILS IF IT DOESNT WORK FOR SOME
http://forum.xda-developers.com/showthread.php?t=1044765
INSATALLATION PROCEDURE :
here are the procedure to install gingerbread root.
-copy all files from sd card to pc(backup)
-now format sd card fat32
-place the gingerbread apk 1.20 in sd card.
-now enable usb debugging settings-application-development -usb debugging (check the box)
-install gingerbread apk using file manger .
-press root and wait .the phone will reboot if it doesnt wait fr some time and see -if it works if not remove ur battery and reinsert ,switch on check if u have superuser icon in application.
INSTRUCTION ARE PROVIDED IN THE ABOVE LINK TOO AND IF THIS APK ROOT YOUR PHONE THEN NO NEED TO DOWNGRADE AND ROOT USING Z4ROOT AVOID BOTH THE STEPS OF DOWNGRADING AND ROOTING USING Z4ROOT PROCEED WITH INSTALLING CUSTOM RECOVERY
First remove nokia drivers or other phone drivers,nokia pc suite,microsoft visual ++ runtime environments installed in pc
Install lg pc suite http://www.multiupload.com/3YHPSRS4Z0 (NEW PHONE BUYERS WILL BE HAVING PC SUITE IN SD CARD PROVIDED BY LG)
Disable LGE VIRTUAL MODEM in device manager (RIGHT CLICK ON COMPUTER- SELECT MANAGE-DEVICE MANGER-SELECT LGE VIRTUAL MODEM-RIGHT CLICK AND DISABLE)
Download the rom file and keep it in a folder
Download kdz updater http://www.multiupload.com/OZTKT703D5
Extract the KDZ file in a folder
Install msxml
Remove sd card
Change your phone display timeout to maximum (settings-display-screen timeout 30 min) and your pc screen saver to 30 min
Connect ur phone to pc make sure u have usb debugging enabled (settings-application-development-check usb debugging)
Run KDZ_FW_UPD.exe (run as adminstrator)
Select Type:3GQCT | Phone mode: DIAG
Choose kdz file v10B from the option menu (THE FOLDER WHERE U DOWNLOADED THE FILE)
Click launch software update.
Wait for flashing to finish.
After the flashing is over the phone will reboot and if the phone doesnt get switch on just manually switch on the phone pressing the power button.
When the phone boots up just check the version is 2.2 then detach the cable from pc
INCASE IF FLASHING FAILS JUST TRY EMERGENCY/CS EMERGENCY(last option) AND TRY REFLASHING AGAIN
ALERT: Charge ur phone to 100 % and dont forget to disable LGE virtual modem,dont disconnect ur phone from pc until your phone boots up completely . If u want to backup contacts just enter into contacts and press menu-import export-export to sd card(u can restore ur contacts later just the same way choosing import contacts from sd card
FLASHING TIME :5 TO 10 MIN
I WONT BE RESPONSIBLE IF YOUR PHONE GETS BRICK WHILE THE FLASHING PROCESS AS FLASHING PROCESS HAS A HIGH RISK OF BRICKING THE PHONE,BUT IF YOU HAVE FOLLOWED THE INSTRUCTION CAREFULLY THEN EVERYTHING WOULD GO FINE.
FOR BRICKED PHONE CHECK THIS THREAD http://forum.xda-developers.com/showthread.php?t=883314 (BIG THANKS TO ERROR FOR THE GUIDE)
Download z4root from here http://forum.xda-developers.com/showthread.php?t=833953
Turn on mass storage and copy the z4root apk to the root of your sd card
Use file manager and choose the z4root apk and install.
Open z4root from applcation menu and click permanent root.
Now the phone will reboot and it will get rooted check for superuser icon in ur application menu.
IF U FIND THE SUPERUSER ICON IT MEANS YOUR PHONE HAS GOT SUCCESSFULLY ROOTED
INSTALLING ANDROID SDK IN ORDER TO USE ADB
First install JDK and JRE from here http://www.oracle.com/technetwork/java/javase/downloads/index.html (choose your appropriate os)
ANDROID SDK LINK:http://developer.android.com/sdk/index.html (LATEST VERSION r10)
Install ANDROID SDK
Click next
Now it wont show next option to proceed just hit back once and click next again (you will be able to proceed with installation now)
Run android sdk manager(note :Run as Administrator orelse it wont download the packages) it will show various packages available just click cancel.
Click on available packages-android repository-uncheck SDK PLATFORM ANDROID ALL VERSION EXCEPT 2.2(U CAN LATER INSTALL THE VERSION U REQUIRE LATER WHEN U NEED IT)
Click install selected
Click select all and proceed with the installation.(this might take a long time depending on your connectivity)
NOTE:IF YOU DONT RUN AS ADMIN THEN THE INSTALLATION WILL FAIL
INSTALLING CUSTOM RECOVERY

UPDATE:13/05/2011 CLOCKWORK V3.1.0.0 LATEST RECOVERY CAN BE OBTAINED VIA ROM MANAGER DIRECTLY.
DOWNLOAD THUNDERG CUSTOM RECOVERY AND FLASH IMAGE FROM HERE http://www.multiupload.com/2XXSX4X2PX (I have provided all recovery in 1 file to save your searching time and prefer custom recovery 1.2. CREDITS GOES TO THE DEVELOPER

choose swap size 0 mb,ext partition 512mb (IF U HAVE A LARGER SPACE SD CARD MAKE EXT 1024 MB)
select sd ext2 to ext3 (STABLE TO USE EXT3 PARTITION)
select sd ext3 to ext4(be careful in choosing this option as the rom should support ext 4)
finish with the setup
mount sd card and transfer the a2sd file to sd card
unmount sd card
select install zip from sd card choose the a2sd file and flash
reboot
NOTE: USE A2SD ONLY WHEN YOU HAVE A CLASS 6 SD CARD(RECOMMENDED),U CAN USE IT IN CLASS 4 SD TOO BUT SOMETIMES IT CREATES PERFORMANCE ISSUE IF U DONT HAVE A CLASSS 6 OR HIGHER SD CARD.
HOW TO KNOW THE CLASS OF SD CARD- JUST CHECK ON THE CARD IT MUST BE PRINTED ON A CIRCLE DESIGN, IF U DONT HAVE ANYTHING WRITTEN IT MUST BE CLASS 2 | AVOID USING A2SD IF U HAVE A CLASS 2 SD CARD IT MIGHT RESULT IN BIG PERFORMANCE ISSUE
IF YOU FIND YOUR PHONE INTERNAL SPACE DECREASING IS JUST BECAUSE OF THE DALVIK CACHE.IF YOU WANT TO MOVE DALVIK CACHE TO SD CARD ,OPEN TERMINAL EMULATOR OR ADB AND TYPE
su
a2sd cachesd (move dalvik to sd card)
a2sd cachesdreset (move dalvik to sd card and clears contents of dalvik-cache)
a2sd cachepart (move dalvik to cache partition)
a2sd cachepartreset (move dalvik to cache partition and clears contents of dalvik-cache)
Boot into clockwork recovery.
go to backup and restore -create a backup of your current rom (Note:If already backup has been done then avoid this step, backup created using amonra or thunderg wont support restoring using clockwork)
wipe data/factory reset
wipe cache partition
wipe dalvik cache
mount and storage-format system
go to mount and storage-format sd card
advanced-partition sd card-choose 512 mb (preferable)or 1024 mb (it automatically creates ext 4 partition, class 6/4 is preferred)
mount and storage-mount usb storage (make sure usb debugging is enabled)
copy the rom zip file to the root of your sd card
unmount
install zip from sd card-choose the rom zip and install
flashing takes 3-5 min
reboot
IF U WANT A2SD AND TWEAKS TO BOOST PERFORMANCE CHECK POST 2.TO BE PERFORMED JUST AFTER INSTALLING THE NEW ROM

don't you think we already have enough guides over here?

Kindly remove the installation of custom recovery via adb. Show it via terminal emulator. Its hassle free and from phone only.
Also attach the recovery 1.2 here. Also guide the user to unzip it.
Also attach darktremor script here.

This guide is wonderful, I was just about to post on another thread http://forum.xda-developers.com/showthread.php?t=844483 how they should try an clean it up a lil, it is quite a mess over there. My P509 should be here on 4/20/11, cant wait to get started since I already know it is coming preloaded with 2.2.1(1st time Android user coming from 5 year stint with WinMo). Ive been researching the P509 for about 2 months(4-8 hours a night) here on the Android side of XDA, and it has been a journey, anyway your guide will definately help the average noob, in my case I really appreciate the lessons I got from browsing through the different threads and forums associated with this phone. All in all best guide Ive seen so far really sums it up.

Neat guide. I'd suggest one tiny thing. Its not really mandatory to install the adb. Mentioning that as an optional would keep things clear

I really would like to believe the above mentioned statement and that you missed my thread [HOWTO] Rooting, Installing - Android SDK, Custom Recovery, Custom ROM's dealing with the same topics except for the fact that we exchanged multiple PM's during your attempt at following the instructions given in my post.
This post feels like an abridged and in certain respects incomplete version of my above mentioned post in most places except for the a2sd part which I chose not to include as certain ROM's include a2sd by default.
Anyway, I appreciate your attempt to help out newbies.

Moved to general, has there are some threads already in dev section for help.
Cheers

Hey flashing d new rom, flashes new kernal also or it jst flashes a new rom ?
Sent from my LG-P500

It depends on what the developer has included - a new kernel or stock kernel.
Usually custom ROMs come with a modified kernel because there are improvements compared to the stock one.

just check the rom u r installing and it must be mention in changelog whether the devleoper has included the kernel or not but most of the time the kernel is included , if u are not satisfied with the kernel rather u can try diffrent kernels available over here in xda

sorry to say mr charlie that u have edited a lot of stuff in your post LATER and have put the information correctly in order and describing it properly ,its true that your thread helped me which is this 1 http://forum.xda-developers.com/showpost.php?p=12006447&postcount=61 and the 1 u pointed out but as i said it was scattered and not properly arranged orelse i wouldnt have taken an initiative to write. no harsh feeling it was just my attempt to help others so no use promoting your thread let the newbies decide which they want to follow.
there was minor flaws in your thread which landed me in bricking my phone but but thanks to error for his guide .It was the ultimate saviour for me and for many might be.
i have just put in all information in order and removed unwanted writings.
STILL GOOD TO HEAR U LIKED MY EFFORT

well! the best explained thread for installing custom rom
very well organised,followed it and now using cm7 GREAT
thank you

This is a very useful guide for me who is very new to android. Its always important to have less complicated guide with updated methods every now and then for the newbies. Good work.
A few questions though. How important is it to remove visual C++ from my PC? I can see many versions of it installed on it by default (I never installed it myself). I am afraid removing it might mess up other programs on my PC. Also isn't the default Gingerbread app2sd enough to run apps from the sd card? What additional features does Darktremor have?

its not that important as i myself have it installed c++ 2005,2008 but somtimes it might block flashing that why its suggested to do so,as for a2sd many rom has is pre installed but some requires flashing a2sd as for fransisco tweaks it helps in sustaining battery so i am not so worried about it as mik cm7 for me seems to be stable but i am looking forward for ungaze contribution to xda http://forum.xda-developers.com/showthread.php?t=1042828 as using this really makes our phone perform to next level just waiting for his updates..

using the 32 bit mode is preferable just remove those as it wont hamper any performance on ur pc. it will get automaticallly updated from some software or games while installing so no worries on removing .
thats my recomandation juust follow the thread precisely and vrything would be fine let me know the result
