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

Possible way of getting ROOT + 4G (HSDPA) speed for p925 (rogers or at-t)

Hello everyone, I know post are existing in the development section for this but I think I may have a way to get 4G speed on p925(g) (rogers optimus 3d and at-t lg thrill) combined with root.
EDIT #2: If kdz flashing worked for you but isn't working anymore for no reason, please read this before asking : http://forum.xda-developers.com/showthread.php?p=22023493&posted=1#post22023493 lg effers blocked the acess to kdz flashing since their last version updater
I'm not a pro Dev but mods will be happy, before posting I READ and try to post something usefull.
As I was searching a way to get a better bb for my rogers optimus 3d I found many interesting things but all were uncomplete.
1. The LG Optimus 3d seems to simply be a LG thrill (don't be fooled by the G in P925G it seems many ppl are just ommiting the G to do shorter)
2. This post : forum.xda- developers.com/showthread.php?t=1449021
(pull off the two spaces after xda-)
Showed me that there was a working stock gingerbread ROM from Brazil that is having the right frequencies to give 4G on rogers (tested by myself and it's a GO!) and on at-t.
The only problem with this rom is that currently There seems to be no way to root it (not even the latest superoneclick 2.3.3 can do it).
So basically it's not that bad because you've got the choice of getting STOCK GINGERBREAD WITH 4G SPEED ON P925 by flashing v20a kdz (follow first link)
But many of us want to get further. ROOT + 4G is almost a requirement for a phoen to be respected according to me and many other.
So acording to the post there is 4 THEORETICAL ways to get root + 4G on a p925
1. Follow the instruction in the post, and if you're one of the lucky bast**ds for who the second kdz installation doesn't push the european bb well you're good to go but even after 5 times repeating the process the bb was always getting flashed.
2. Get the superoneclick guys craking, so we can get Root access on the brazilian ROM
3. Get who knows who cracking the brazilian or european kdz file to isolate the bb (from brazilian) or the ROM (from european) and then flash them in the according order to get a rootable ROM + the brazilian bb together (we know they are compatible since bast**ds from #1 are still getting data).
4. Install only the ROM from someone who would post an european .bin (without bb) of v21a to be installed over the full brazilian kdz.
So basically i'm widening the call for this .bin file search but I think there might be another way!!!!
I've seen phones reacting different ways when combining a froyo baseband on a gingerbread ROM.
a. the phone bootloops
b. there is no signal but phone boots fine
So basically if the p925 is doig b. it would be possible at the place of searching a v21a bin (that seems hard to find) flash a rootable froyo bin . So I'd like to know if any of you still have one of the rootable bin that were found in this post : forum.xda- developers.com/showthread.php?t=1246678
I would have already tried for myself but since megaupload closed fileserve does not support share anymore....
So if someone could provide me with
a. one of the rootable .bin file in this post :
forum.xda- developers.com/showthread.php?t=1246678
and I'll tell ya if it's a WIN or if we have to get back craking!!!
b. Tell me if this workaround fits:
1. Flash V20a brazil kdz (found here forum.xda- developers.com/showthread.php?t=1449021
2. Flash a rootable froyo .bin using this method
forum.xda- developers.com/showthread.php?t=1244490
3. Root the froyo ROM
4. Install CWM
5. Flash a gingerbread rom made for p920 NOT FOR p925
6. TELL US THE RESULT!!!
BE SURE TO KNOW WHAT YOU ARE DOING BEFORE FLASHING KDZ AND BIN FILES... I'M NOT RESPOSIBLE FOR ANYTHING HAPPENING TO YOUR PHONE. BUT IF AS ME YOU GOOGLE AND READ YOU'LL PRETTY MUCH ALWAYS FIND A WAY TO UNBRICK... DON'T ASK I WON'T DO THE GOOGLE FOR UNBRICKING YOU!!!
so I know it's a long post but.. I prefered to go into details and expose my point right with all the sources article
Good luck to all and KEEP ON CRAKING!!!

Ill see if i still have the rootable .bin froyo tonight when i get a chance if you wanna do that nd let me know how it goes cuz im curious

try that out its the thrill froyo bin

Does not work. It still restores the froyo baseband. If you delete the baseband from the folder the flashtool won't work at all.

I don't think that's going to happen yet

You can flash just the .bin file i thought

I couldn't it just kept saying error in the lgflashtool. With the fls and bin in the same folder it flashed but replaced the radio in the process.

Hmm i wish i had time to get on the comp and try this on mine right now

I'm going to try it when I get home, and i'm going also to try with a blank .fls file just to see if it flashes nothing.

Don't know if it's my windows 7 environment but i'm getting some trouble even before the software trying to flash... I enter the .dll file then the .bin without the .fls and when I click ok the program automatically crashes... Any idea what it could be so that I can try to flash the froyo bin over my v20a baseband?

Are you running as admin?

Try rebooting comp and do it

OMG.... A chance I'm already on a rooted rom.. They are truly making us struggle to get good roms on this phone.. an again we are pretty much screwed to get the right baseband on our phone... If anyone finds a tutorial or anything to do so.. HELP!!

[Q] How to flash back to stock rom and unroot my P970?

Dear All brother
I just want to flash back to stock rom and unroot my P970 like initial status. Is there any tools or method to do so?

It's very simple, just follow the Tutorial: LG P970 (P970H) unbrick/flash using SmartFlash Tool and install whatever version of firmware you had initially, you can find V10 firmwares on the Firmwares LG P970, P970H thread.
If you want to get to the official V20 firmware, just upgrade your phone using the LG program (the one that came on the CD with your phone).
This way you'll have an "official ROM" on your phone and it won't be rooted either (it's just like it came "from factory").
Btw, you'll loose the root and the recovery functionality, but i think that's what you wanted in the first place
EDIT : replaced Samsung with LG, i was reading up on modifying my Samsung Spica and somehow mixed up the postings

[Q] Stock apps/ROM reset

I just got a rooted Optimus 2x. It has the stock ROM. The previous owner had removed many stock apps including Google Talk, music player which I would want to reinstall but I can't reach him now.
It has some backups because of Root Uninstaller, but not every app is there.
I found some links for all Optimus 2x stock apps but they aren't working anyome.
Is there any way I can reinstall these apps? Or do I have to reflash the stock firmware or something?

You should reflash
Sent from my Optimus 2X using XDA

So before I reflash can anyone confirm if this is what I should be doing?
Download my firmware from here: http://forum.xda-developers.com/showthread.php?t=1035041 (Hungarian one)
Download Smartflash and Baseband (0725-V20q-Baseband) from here: http://forum.xda-developers.com/showthread.php?t=1658047 And follow the instructions. But also select the firmware file too.
The problem is the link for my baseband is down and I can't post in the thread.
Also after I flash it, I will have to root it again, right?

After u flash the stock firmware, the baseband will be flashed as well. So unless the stock baseband is not working with ur network u dun have to flash the baseband again,
Yes, u will have to root again
