lg optimus 2x upgraded and downgraded successfully - LG Optimus 2x

Hi,
I have LG 2X P990(Indian stock ROM V10B).Few days back i have successfully upgraded my cell with Europian stock ROM V20L(official/leaked)....over V10e -725 BB...using KDZ updater....having V20L_00.kdz file..
Upgrade was nice but ih has problem with 3G data connection...it connect with long delay....
Today i flash back again my P990 to V10E-FRG83G-1035.21_20110725. I downloaded it also from XDA-developer....but this time i flashed it with Smartflash software...in which i have to select 2 extrected files .bin and .fls
BIN_LGP990AT-00-V10e-ESA-XXX-AUG-01-2011_0.zip.......
Please see procedure to flash the mobile...in XDA developer forum...

To be honest you really need to put Clockworkmod Recovery on there and using that to change the firmware. You can find instructions here although there are probably some on these forums as well.
I would then recommend either trying a firmware such as CM7 or something like Wiui. There are plenty of roms based on the official releases as well and they can be found both here and on MoDaCo.

.
Thread moved. Would advise you to read forum rules and post in correct section.
Failure to comply with forum rules will result in an infraction and/or ban depending on severity of rule break.

Can u post link of tutorial that u followed for flashing kdz?

[HOWTO] root Koodo version of Optimus One P500h 10v

!!ATTENTION!!
THIS INFORMATION HAS BECOME OUTDATED. ​
There are probably newer and easier ways of accomplishing your goals that are now available. Read the entire thread for tips from other people about how to get your phone rooted - their suggestions are likely to be better options for your needs. I will not be maintaining this thread, but I will leave it up as a record for others to read. Good luck!

Original Post:
Hi. I had trouble getting my Optimus One from Koodo Mobile rooted. So, here is some info that I hope will help others get through the process a bit faster. I mainly followed the instructions in various threads from XDA, but I needed to do things differently.
!!! REMEMBER, THIS IS INFORMATION FROM A BIT OF A NOOB. I'M JUST TRYING TO HELP.
!!! ALSO, I TAKE NO RESPONSIBILTY FOR ANYTHING GOOD OR BAD THAT COMES FROM APPLYING WHAT IS SAID IN THIS THREAD.
!!! THIS INFORMATION IS ONLY INTENDED FOR USE ON THE OPTIMUS ONE FROM KOODO MOBILE RUNNING FIRMWARE VERSION 10v.
It is probably not worth asking me any questions, since I barely got through the process properly myself.
-----------------------------------------------------------
Drivers
So, first I installed the LG PC Suite software because I think that gets you the USB drivers needed for this phone. I think LG calls it "Download LG Mobile Support Tool to PC" on their support site at:
http://www.lg.com/sg/support/product/support-product-profile-mobile-redux.jsp?customerModelCode=Optimus%20One%20P500&initialTab=drivers&targetPage=support-product-profile-mobile-redux
Telus 2.2 firmware version V10G_00
So, since android 2.2.1 is not rootable on Optimus One, I had to downgrade to android 2.2. I found a link to a Telus version of P500h that is android 2.2 at the following link (make sure you download the one that ends in "V10G_00.kdz"):
http://forum.xda-developers.com/showthread.php?p=12253960#post12253960
Installing Telus firmware using KDZ
I followed steps #2 through #8 from the following link:
http://forum.xda-developers.com/showthread.php?t=875881
KDZ worked well, just so you know.
Rooting
Now I used "z4root" to permanently root. It was super easy (way easier than rooting my MT3G Slide). z4root is NOT in the market anymore so you need to sideload it onto your SD storage, then install it with any apk manager.
This site:
http://forum.xda-developers.com/showthread.php?t=901247
led me to this site, where I downloaded z4root from:
http://forum.xda-developers.com/showthread.php?t=833953
After that, I was all rooted up... finally.
So, I obviously am NOT trying to take any credit for the real efforts made by others. I want to say thank you to all people involved with the links and programs I referred to. I really appreciate what people do for others here at XDA. My phones would not be rooted or other kinds of fun without those people.
THANKS!
-------------------------------------------------------------------------
On a bit of a side note, you might want to unlock you phone too... so you could use it with FIDO, etc. So, I used a site called "mobileincanada". It was $20 and took less than 24 hrs to get the code. I was happy with that.
Nice write-up, I had to follow a similar path. The most trouble I had was finding a firmware that worked.. I ended up using the same TELUS firmware. It works great, much faster than the original Koodo firmware.
Sorry for my question: what is the difference between your P500h and the other P500 devices? is it a branded device with special firmware?
I thought, all P500 can be flashed with every P500 *.kdz (for country) or XDA ROMs
for P500
I wished you wrote this yesterday but thanks. I figured it out yesterday . This is the sickest 150$ phone I have ever had. I get 1100 quadrant score :O
If you want a stock, rooted 2.2.1 (Telus V10S - same as Koodo's stock V10v)

this may be off topic but what are the custom roms that you can flash to p500h? any one tried installing one?
Thank you, I thought I broke the phone when I flashed V10A_00, it wouldn't boot into screen. Telus one indeed is nicer than Koodo's.

Thanks Kwen! This is very useful - now no need for the kdz updater.
Edit: or now we can keep the Koodo version of 2.2.1 and just root it using Gingerbreak (http://forum.xda-developers.com/showthread.php?t=1044765) - no KDZ needed, no recovery needed (prior to root). Obviously, recovery is still recommended after root.
the only question that i have is where can i GET the stock 2.2.1 for my provider? i'm with Koodo, and i live the custom roms, but i need to flash back to stock to see if i can get my mms working correctly again. and i apologize in advance if this is the wrong thread.

I'm in Mexico, and use p970h with Telcel, but at the start of the month I wasn't able to root it, and I don't know if it's rootable yet
Or where to download Zeus in the case v20a is not rootable yet

Ok look it is exactly the same method. But you have to press the link for v20a and once you redirect in the russian forum press the link from the 1. step. Then you will be redirected to the download. Next to the 218.71 there are 2buttons. Press the left and on the next screen press the button that will appear after 5seconds. Those are the bin files you need. And then do the procedure for the v20b but instead of the bin files it says there use the bin files you downloaded.

You are not gonna be able to root if you update to mexican V20a. I tried with my countires rom. It's a no go. Individual versions for countries does not have a root method unfortunately. LG made sure of that.
But, in the first link which gsal given you see there are 3 patched ROMs. V20"a","b" and the last one is "n" (not e, it's a typo). If you want a rooted Gingerbread, you're gonna have to flash one of these. I'll say go with V20b, thats what 'm using and its good.
You could try downloading the ROM from here and using this guide to root it.

Help!!! Help!!! Help!!!

Hi all,
I am really ashamed to post it here but no one was helping me in QA threads.
My problem is, I have lost my phone's touch after rooting and installing cwm with AIO toolkit.

So try different bootloader and rom for it also with custom kernel. If software changes doesn't help it could be hardware problem so you should take it to repair service it may require digitizer replacement
As you say you flashed many roms so one of them atleast i believe it had custom kernel
in my opinion you should go to repair service before you make it worse

This phone is really unbrickable via sw. I happened the same blackout but found the solution searching on xda forum.
When smartflash or cwm do not have good end you must nvflash a new rom (loosing your internal sd data).
Go to Homero2 xda site and download the nvflash rooted 20s rom. After doing it you'll have your 2x working with that GB rom.
Then you can do many things:smartflash an original LG rom or download a custom rom new or old bl, change the bl with AIOT etc... and use cwm for new installation or for restoring backup.

Dear, thnx for your support, my real issue is No Touchscreen after rooting and flashing original as well as custom firmwares. Even aroma installer's touch wasn't working. the phone is in repairing shop and let's see if replacing digitizer fixes it. :/ By the way, when I flashed v20 rom which was NVFLASH packaged, the phone failed to start and suddenly went to black out as soon as LG logo appeared.

[Q] How to flash original firmware?

Can someone please give/link me a detailed tutorial on how to flash the original firmware?
I'm not sure if this is relevant, but I've just unrooted my optimus 2x using superoneclick. Also, it's been a very long time since I flashed a custom ROM, so I have no memory of what ROM I'm currently on.
Thank you.

flash original firmware
I suggest you to flash the original firmware with smartflash (p990 edition).
I try all other methods but i found smartflash more easy than the others.
Thanks for the responses guys, it's helped me take a few steps towards the goal
However, I'd like to ask another question regarding the baseband, and yes, I HAVE read over tonyp's brilliant thread about it, but I'd like to clear something up.
My Optimus 2x was parallel imported, but I have no idea what country it was imported from. Tonyp says in his FAQ that he doesn't think it matters what country's stock ROM firmware and BB you install, so can I truly install any country's firmware, and then use the GetRIL app? It's not like I must install firmware from the country closest to mine (New Zealand) or anything right?
Thanks in advance.

[Q] First root and custom ROM flashing

Hi,
I am new in this topic, and I want to try out custom ROMs. I have chosen the custom ROM I want to try out (for me this time it's gonig to be CM 10.2 - http://forum.xda-developers.com/showthread.php?t=2435716 ), and I've read some articles and forum threads about this matter.
My Galaxy ACE S5830 runs on Android 2.2.1 and has never been flashed (as far as I know).
I just want to be sure that I won't make any mistake so I need someone to write me down full process that needs to be done. I don't fully understand what comes first and what comes last therefore it would be helpful if someone here could describe me step by step instructions. I have downloaded everything suggested including drivers, cwm, odin and root and above mentioned custom ROM.
I am new in this subject meaning that I have never done this things with my phone.
Also I am not complete layman and I have good software understanding so I don't need extensive descriptions.
