Heloo,i have a problem with my Lg Optimus 2X(P990) and i hope you can help me : last year in december i saw in rom manager-download rom CyanogenMod and I tried it,but i haven't done the backup of original program (Android 2.2Froyo).When I wanted to come back to original android I did not have what to come back and i started to look for a similar version of android to the internet and i found on this site a few versions , i downloaded this version : BIN_LGP990AT-00-V20l-EUR-XX-OCT-20-2011+0,and i instaled with smartflash p990 after a tutorial that i found on youtube ,it works but my problem is when i want to upgrade to 2.3.3 or 2.3.4 it doesn't let me do it,it says : "Software update is not suported for this model" and "Select the Contact button to contact for lg Mobile Phone Software Update online ".
How can i fix this problem ?? can anyone help me with this ???
On his back,under batery, it says that it was made in Korea.
You need to downgrade your baseband.
Follow this guide http://android.modaco.com/topic/335...aseband-release-103521-20110725-v20l-version/
and use this baseband http://loadbalancing.modaco.com/download.php?url=mf/?pb62vt254c44n1w
can you tell me why? also ive just started using CM7 (version .87 by temasek) i used a LITE kernel and still using the default (RIL)(baseband) that came with my fone. ( 1035.21_20110725 ) can u tell me. is there better one matched or unmathed that would give me better battery..
Hi MIFFO858 ,I tried what you said but still doesn't let me upgrading to gingerbread,what else can i do to fix this problem ?!!!!
LG updater is crap, so you should flash v20q with smartflash or v20r kdz or v20r cwm rebuild by Flix123. Btw v20l is 2.3.4.

I did update the gingerbread and now I want a back Froyo LG Optimus 2x. I want to change it because I have problems with the network 2 g and Team Viewer does not work either.
Someone help me?

But I think there must be other solutions....
try CM latest nightly. for meverething is working fine
I also suggest to find ways to fix your issues on GB since it gives better overall user experience than froyo.
This is my fist post in the forum so please don't judge me too much
So , in order to install a custom rom on my OB he must be based on the same software version as the desired custom rom. For example the NOVA rom is based on V10c but my phone is on V10a so in order to install it I first need to flash my OB with V10c using SmartFlash for example. ( Of course the pone must be rooted, having the CWM...)
Is this the same case with the CM7 ( based on V20,which is a Gingerbread ROM build from scratch ) , can I try to install it even if my phone is running on Froyo 2.2.2. ?
It seems that the LG updated the B2C and the KDZU and R&DTT are not working. So for now there is no manual way to upgrade the software version from v10a to v20. We can only use SmartFlash to upgrade and downgrade but he needs the .bin and .fls files and not the V20N_00.kdz. In the list of all the available bin/fls ROMs there are no roms based on V20. (Sorry cant give the link as this is my first post). And there is no way to convert the .kdz into .bin and .fls files.
So the conclusion is that for the moment I can't upgrade from v10a to V20 if the version is not officially available in my country. And I can only install roms based on Froyo. Is this right ?
No, this is wrong ...
You can go from V10a for CM Rom without having to change the version of software, for example.
The software version you have, no matter anything with the rom that you will install, it is not necessary to have the same software version of ROM, since the rom replaces.
You can go from 2.2.2 (V10a/V10c/V10b, etc.) to a 2.3 ROM without problem.

Thank you ! I installed the Marvel v2.1.1 and its looking nice ! Much better than the crappy LG UI. I hope it will perform better as well.

The zip worked with CWM...running stock like a charm...
Taken to the service center...some dust issues with the socket...they cleaned it.
Btw can you point out what changes did Flix123 carry out ?

must be some bulky useless LG stuff for sure....I dont remember my friend...but forget what are the changes....whatever he did, I am sure it will be good ones.....
If you are done with the service stuff, try this stock ROM with my kernel....if you want. Kernel is built inside the ROM using Aroma installer.Amazing ROM by CARBURANO...all credits to him for the ROM.

If you use this ROM V20q, you will have to try, if the update tool works. I find those LG tools are working randomly.
If you cannot update and want stock ICS on your phone, restore with Paul O'briens Smartflash, then you erase all traces of rooting your phone!
Cheers

On the other hand, will the stock ICS rom be as good as something like the hybrid Temasek rom anyway.
If we had the drivers for the video chip (and HDMI?) it would be perfect. As it is it's still better than stock in every other way.

i seriously think ics wud be better than the customs...atleast they will be bugfree and as u know stocks roms r always better user friendly then the customs.
Im using temasek rom and symbiosis kernel at present.Will be back to stock gb in a few days
Hello,
The first two days, the new V30A was fun to use BUT now it's a real pain, it is slow as hell, the worst are all the internet browsers that take ages to load and show the keyboard after 15 seconds or more when you try to enter text, it's laggy it's ridiculous.
How can I go back to V20S with Smartflash ? Will the partition be created automatically ?
Thank you. :good:
Jst smart flash v20s but then u again need to root n put cwm.......or jst do nvflash from this link

hey guys,
you dont need to smartflash, then root and then all that grandma stories
just search for Homero's clean V20S CWM rooted NVFLASH ROM and then it is all done with one nvflash....
Thats it guys....clean and simple....KISS....keep it simple and straight
Hope it helps
I have this doubts
Is the smartflash the same as the kdz software update tool?
if is so I just have to flash the kdz I have from my carrier like I have done many times in order to get back from the v30A?
I would like to go back to my carrier`s one since It has the only baseband that doesn't give me trouble so I don't care about flashing cwm again
I thought that we could not get back to a GB rom when we've installed a ICS rom ?
So, if I flash my phone using Smartflash, it will do it all automatically ? (i'm talking about the partitions issue) Thanks
i guess you're using stock V30a from LG update tool right? why don't u try some custom rom b4 going back to GB. I'm using TG ICS rom v30a and it's awesome :good:

No I flashed the V30A with smartflash, LG update never works for me...
I only want to use a stock rom !
Can't I go back to V20S using Smartflash ?!
My phone was unable to enter sw update mode so I flashed a 10b firmware using the emergency procedure ( vol up + vol down mode ). I was back from 28e. The SW update mode ( smartflash compatible ) was working again so I flashed the 30a kdz.

try this :
Settings-->Developer options-->Background process limit = choic at most 1 process
whit this it is very fast
Maybe, but it still lags sometimes and it's slower than Froyo or GB i think

This Rom is really fast and based on 4.0.4 Stock Rom.
