LG 2.2-2.3 Rooting

Hello,
I have an LG P500H that according to the settings menu is currently on Android version 2.2
I've read in countless places that this device is eligible to be upgraded to an official 2.3. Through the LG support tool a notice displays there is an available update which im assuming is the 2.3 itself.
My question is with regards to rooting. I have located a thread about rooting this device on 2.2 firmware but nothing specifying any process for 2.3. If I root on 2.2 my assumption is I will lose my root once I upgrade. How would I go about rooting this device on official 2.3 firmware.
Thanks to everyone for reading.
-------------------------------------------------------------------------------------------------------------------------------------------------
Here I will list the only post I've found referencing this involving rooting through ADB. Can anyone confirm? Or suggest a safer method to ensure success with no issues? The post is as follows:
The LG Optimus One P500 is the one of the best budget Android phones around. Now it can be updated to Android 2.3.3 Gingerbread, then the purpose of writing this article is to help you to root stock gingerbread in an easy way. LG Android Phones
How to root Android 2.3 Gingerbread on LG Optimus One P500:
1. Read everything first and after do what is necessary:
What Is ADB and How To Install It With Android SDK, please go to here.
INSTALLING ANDROID SDK ON YOUR WINDOWS PC from here)
Don’t forget to restart your PC after installations. LG Phone Problem and Solution
2. Download and install SuperOneClick. You can download the tool from here.
3. In adb:
adb devices
adb shell
echo 1 > /data/local/lge_adb.conf
After that open SuperOneClick and root using pneuter. Reboot phone and update Superuser from Market.
This instruction works fine on my LG Optimus One, I had some problems updating superuser, kept force closing, but after restart, it works. hit thanks if this was useful for you.
EDIT: So I try to update software through LG support tool. The first screen of the tool checks the software and says there is an update available. Doesn't specify what version. When the option to start the update is selected the second tool launches and says device is not able to be updated. Another question would be what exactly is going on with that? and how to go about getting the official 2.3 on this P500H. Thanks.

This is ridiculous.
I check the TELUS website which is the carrier for my device. Turns out the only "update" listed on their end is 2.2.1 and the instructions stated my device needed to upgrade as I was running 2.2
So I go ahead and update my device and everything completes as the instructions stated.
Well, now the phone is stuck in a bootloop at the android logo and will not go further. Thanks TELUS.
Edit: Hard reset fixed this issue, now running 2.2.1. Getting really fed up with this so called official 2.3 that I can not seem to get. Anyone with answers please assist.

heres the official gb rom:

Thank you for the link. I looked over the thread and noticed that the post mentions v20g and v20c versions for download.
I'm guessing these are international versions as I have checked my phones About menu and noticed I have a software version listed as LG-P500H-v10s
How would this impact installing official 2.3 or is there anywhere I can acquire a version for my device.
Thanks

Doesn't really matter which one you use
V20c is unbranded, don't know about v20g.

Would it be correct to say that the reason I cant get this software update through the LG Support Tool or on my Canadian carriers website is because it isn't offered at this time by my specific carrier?
Therefore its been put out mainly to international carriers, hence why I would have to use an unbranded generic firmware? Just wanted to inquire so that when I complete the flash I'm fully educated as to which version I'll be using. Does anyone happen to know if NFC (near field communication) is supported in this unbranded version?
EDIT: Just to add. There appears to be a notice at the bottom of the page mentioning no 2G/3G data - wait for new release. Is this relative to the official 2.3?

So I am experiencing much lag on the 2.2.1 firmware that I am currently running ton this P500H for these reasons I will be attempting to flash to the official 2.3 in hopes of better performance.
Looking to clarify some instruction from the OFFICIAL LG GB thread listed in one of the responses. The tutorial states to flash "the russian way" and provides a HOW TO for using the LG DMP tool. In the tutorial the method says "This HOWTO is for users who want to switch from stock LG 2.3.3 ROM to CM7 or other older ROMs that are NOT based LG's on v20 ROM or vice versa"
My question with the statement is how does it impact the fact that Im on a stock 2.2.1 not flashing to a CM7 or vice versa. Which baseband would I be using as I am not sure what exactly this 2.3 is based on and I am running a v10s.
My guess is I would download the second baseband file in the thread listed as "- P500-v20G-baseband.7z is for official v20[abdg....] ROMs and ROMs based upon it (e.g., GingerLOL, v20G stock ROM, customized v20G ROM, 0x0v3rfl0w ROM and GingerCriccoROM)." and then flash the v20g 2.3 firmware.
If anyone can elaborate so that I dont brick this device when flashing
Another part of the article says "Eventually, all new ROMs will switch to new baseband by default, so it is useful as well if you want to avoid the complete KDZ/Russian way flash which wipes everything." Would this mean flashing "the russian way" with .kdz file would mean not having to change the baseband in the LGDMP tool. Kind of like an all in one solution instead of a drawn out process? I found a post with instructions for KDZ updater but dont have a file for 2.3 android to flash. What is the suggested method and steps? If anyone can clarify

Move this to General section..!!
Guess this should be in the General section and not in development..
Theres a kdz file of europe and russian version on xda.. search for it.. flash it usin kdz and you are done.. you get new baseband and then root using superoneclick.. you will lose your data.. but you can back it up using titanium backup.. flash recovery n den you are ready to use any of the new custom romz.. they perform well in quadrants.. not as much as those developed by our heroes like mik andy and all.. but for a stock rom those values are good.. i reverted back to miks cyanogenmod for itz performance.. anyway, if you want a stable, ALMOST bug free rom, go in for stock 2.3.3... there are minor bugs.. like status bar icons not alligned and stuff but you can manage with it...

works perfectly

[Q] No OTA updates, says "up to date" but stuck on 10c

My O2x self bricked after an OTA update (from 10b if I recall correctly). I did not prior to this event flash any other ROM or BB, I just rooted it and everything was working fine. The update downloaded, said it was ready to update, the phone rebooted and then just locked up on "updating software". My friend has an identical P990 and everything went well for him...
I had to reflash the whole phone using USB cable in recovery mode by downloading the 10b stock firmware. After this, the phone won't update itself and if I manually click on the software update it says it's up to date, while my friend received the latest update to 10d. Currently my phone (unbranded) is:
BB v 622 (1035.21_20110622)
kernel 2.6.32.9
Build FRG83G
LGE version LGP990-V10b
Additionally I installed clockworkmod (after bricking) to backup all my phone and then reflashed the stock recovery partition that I found online. Also, I currently can no longer list any "secured" apps from the Android marketplace.
I'd like to bring my phone back to stock situation (which I thought it was) so I downloaded the latest stock (10d) in kdz format from the lg site but before wiping everything again I'd like to know what the hell is going on with my phone and why I see no secured apps and why I get no OTA updates... maybe I can avoid reflashing the phone from scratch.
Thanks for any pointers!

The version of the baseband you are using does not match with the V10B firmware. The update tool then believes you have another firmware version installed.

Thanks for the heads up! What version of baseband should I be using? Or would it be better for me to downgrade the rom? Quicker to change BB I reckon...

i think it is 405 you need to use with 10b

I tried searching for the 405BB but couldn't find it... only the 622 or 725 apparently - does anyone have any link to download the BB aligned to the v10b ROM?

here http://forum.xda-developers.com/showthread.php?t=1008070

I flashed 405BB but when I went to download OTA updates it said it wasn't a valid update package after it downloaded it and quit. To fix it I completely flashed stock 10a and did all the updates until 10d and now it has BB 1035.21_20110725.
I have my data.img partition saved with CWM but before restoring it and wiping the stock recovery for CWM I'd like to save it: anyway I can make an img out of the stock recovery partition of this version for safety with adb? As it pulls or pushes files or apks, I was wondering if there was a utility to create a partition image of the stock recovery and save that... I found a stock recovery img but I don't know if the image is up to date with this version (10d).
Thanks for the help!

[Q] reinstall original rom, update possible ?

Hi all,
I tried the cyanogenmod 7.1 but reinstalled an original rom after a while again. Now my phone says I have 2.2.2 with baseband 20110725, kernel 2.6.32.9 , the version is V10b. I remember there was an update to V10d during summertime. I'd like to have the V10d back... if I use the update-tool it says there is no update available and says I have the v10D version , but on the phone it says v10b ??? Can't follow anymore any suggestions how to get the v10d through update ?
Is it necessary to have the v10d if gingerbread ever comes out , or can it update from 10vb to gingerbread as well ?
Cheers !
Denis

BIN_LGP990AT-00-V10d-NEU-XXX-JUL-25-2011+0
but when checking phone settings, it still says v10b ?

Yeah. The settings/about menu will show you the version of the installed ROM, which is still 10b. The LG Update tool checks the version of the baseband, which in your case is newer. (You can see that version in the Hidden Menu, Version Info, Factory Version.)
To update through the LG Update tool you first need to flash an OLDER baseband, then the tool will let you uprade.
(Or you can smartflash an older baseband+rom, to make sure your phone is in a factory state, with stock recovery and no root before upgrading.)

indeed ! but I've figured out that I only flashed the basband and now I just flashed the .bin file too (the rom) and now I've got the V10d back !

Ah, yes ;-) Assuming the ROM you want is already available in a file, that's another way to do it

I found the list with corresponding countries/ROM versions, then it was a piece of cake. Now it's tempting to try the cmod 7.1 again for a bit longer now I found out how to flash

[Q] LGMobile update service PROBLEM! Help Please?

Hi all!
Few days ago i updated my lg p990 via LGMobile update service to 2.3.4 Gingerbread V20m with no problems. I`m from Serbia btw. Then i rooted my phone and installed clockwork recovery to backup my rom. I made a mistake to do that after i performed root so now when i restore my rom the phone is rooted again and i can`t use update utility anymore! It says my model is not suported. I then used SuperOneClick to unroot and r1-stockrecovery-2x-unsigned zip to remove recovery and it did that but still can`t update or restore original stock V20m rom with update utility. I even managed to install V20l ROM and baseband via Smartflash and offcourse still no update posibility and "not supported model" message. Yesterday i downloaded from XDA, Netherland stock V20m but, guess what, still not supported. Can anyone tell me how to or what to do to make my phone update officialy again with LG tool. THNX in advance

..................................................

Well you have go download correct files. I don't remember very well where the download location is.
But I have managed to do full installation of original lg software over the cyanogenmod.
There is a step by step guide on this forum how to do this.
I am from Croatia and after that my phone accept automaticly update.
Now I am on Cyanogenmod because it is so much better than stock.

I downloaded stock V20m rom from http://forum.xda-developers.com/showthread.php?t=1035041 and still not supported with update. Can u please find what u did and post here!? I don`t know what i didn`t try and nothing worked so far. And i have GPS isue so i have to restart phone with gps ON and then it works. I didn`t have that problem when i updated to V20m first time. I have read that it`s a problem on V20l but not on V20m. U said u use custom rom!? Is everything working properly!? No workarounds to make something work like this GPS problem!?

[Q] Official update problem

I`m from Serbia, I made a backup with nandroid on my LG P990 , after that i`ve updated using kdz to v20m version. As i had some problems i flashed back the v20l i had via clockworkmod. Now i have unrooted my phone, connected to pc, fired up the updater, and it says that i have the latest v20m, duobble checked the phone, it reports v20l. How could i force the updater to perform the update to v20m ?

You need to flash an older baseband.

Flashed 1035.21_20110614 baseband. Now the phone reports LGE version v20l, but the LGMobile Support Tool is reporting Version V10C, and says that the cell phone is the latest version already, and that i dont need to update.
Is this means, that for my phone the latest update is V20L ?
Thanks.

I'm on V20g here in the UK so I would of thought that if your phone say V20L you will have the most upto date rom.
I have just checked and there is no updates for me either saying my phone is upto date.

Most probably i will have to wait for an update. Tried to flash the v20q.kdz tried both methods, with and without http server. It is always asking for internet connection... Now flashed another baseband, updater reports v10d phone reports 1035.21_20110725 iirc this baseband version is in v20l. I desperately want to solve the GPS lock problem, but maybe i still have to wait. Unless i try to flash the V20M via clockwork, i`ve done before, but i dont remember is it working there.
