I can confirm V20L update for Portugal.
The local carriers will require more time to add bloatware to their ROM update releases.

We can all check official ROM updates for each country using the LG Mobile Update tool.
a ) Start the application without the phone connected.
b ) Choose "Options & Help" menu -> "Country & Language"
c ) Select a country from the list which you want to verify (wait a few seconds for the app to update)
d ) Choose "Customer Support" -> "Supporting Model"
e ) Find the entries with "Model" column having the "LGP990" entry form the list.

Hello Guys,

have one question to persons who are using official update from LG, if there is really point to switch from cyagenmod 7 to official gingerbread?

Maybe some of you have experience in comparing the official gingerbread and CM7? what would your opinion about that?


The strange thing is that have my stock froyo backup made via ROM manager, when try to recover that and boot- optimus was stuck on lg logo,

wiping data did not help much, so switched back to CM7 by recovering the backup, which made before trying to repair stock FROYO

The question is if there are way to make it directrly mean CM7-> official update?



THANKS A LOT FOR YOUR OPINIONS IN ADVANCE :)


You're stuck in bootloop is because original is on ext3 and since you're in cm7, must likely you have convert to ext4, i had the same problem earlier, but if you use Paul's back to ext3 follow by factory reset + wipe cache + dalvik's cache then only revert, it should work

Is the conversion to EXT4 made automatically when you install CM 7.1?

I installed CM 7.1 through ROM Manager and that's it. So I'm wondering if I'll have to revert back to EXT3 when installing the new stock ROM.

I tried cm7 earlier and it was converted from ext3 to ext4. You can try to convert back to ext3 before you do anything with official LG rom (their's still in ext3, where most custom rom have ext4 & yes its automatically converted for performance)

The conversion is automatic, you need to convert back. Infact, I wish CM had not done that conversion and just mounted ext3 as ext4 the way it did before the auto conversion was made. CM7 can be installed on ext3 by removing the format command in the update-script, I have tried it and works but a pain to edit on every nightly!

Thanks for advice


Other question was if there any point to switch back to original LG rV20L rom from CM? ( Mean performance, stablity?) CM is much more stable comparing to original FROYO from LG,

but still have some issues, using CM 7,1 at the moment

I cannot answer your question based on experience (downloading v20l at the moment with my crappy dsl1000 connection), but having done backup and recovery with several roms over the last months and the
rather easy way it is done, I'd give it a shot.
What I can say is that my own problems with the 2x seem to be coming from several apps that seem to cause problems (especially some task managers, battery savers and the like).
My own reason for even trying custom roms was not performance or stability of v10c but the lack of dual core support, power consumption and known security issues of froyo.
I've had a few smartphones over the years (iphone 3gs, nokia n95, blackberry storm, htc magic) but the power consumption of the 2x made them look like real power savers.
Pauls custom from from mid october was the first one I'd call ok and that I hadnt need to plug in almost every time i came near a power source.
But I had a few problems with it(camera not working and gps fix taking an eternity) and I wanted to take a look on the official version although my expectations are not that high.

And as I wrote, the way back to custom roms is always open...

Hi all,

Just an update on my experience with EUR v20L from GR4 on my locally-branded (StarHub SG) O2X set:

Firstly, I had to get the "original" firmware recovery image to "replace" CWM.

Secondly, I couldn't get KDZ flasher to work (kept crashing on my Windows 7 64-bit OS) despite doing everything including using the latest v3.5 drivers and providing the "latest" LGMobileDL.dll to the KDZ_FW_UPD.exe.

So I ended up flashing the four baseband files separately (largest to smallest), re-installed CWM, wiped everything (data, cache, Dalvik), then installed Paul's deodexed CWM image (with my custom changes as follows), wiped cache and Dalvik cache again.

Changes to build.prop as follows:
  • changed/reverted:
    • ro.product.device=p990_EUR-xx to ro.product.device=p990
    • ro.product.manufacturer=LGE to ro.product.manufacturer=lge
    • ro.build.product=p990_EUR-xx to ro.build.product=p990
  • added:
    • user.feature.ntp=true
    • persist.adb.notify=0
I also removed (zero-byted) the following /system/media/audio/* files:
  • PowerOn.mp3
  • PowerOff.mp3
  • camera_click.ogg
  • VideoRecord.ogg
Unfortunately, the camera and video recording sounds are still there (but the camera sound can be silenced via in-application setting).

Also, I "tried" the "other lockscreen", but didn't see any difference in "smoothness" as claimed though.

I also discovered (was rather obvious, but I didn't think about it) that the APNs from the EUR v20L don't have any APN settings for local (Singapore) telcos... so I had to grab it and add it in.

I also ripped out "useless" (at least to me) APKs:
  • Miscellaneous:
    • AndroidBackup.apk (Android Backup)
    • LibFlashPlayer.apk (Adobe Flash Player)
    • MS_lge_for2_2_Ver7_1_07785_signed.apk (F-Secure)
    • PolarisOffice.apk (Polaris Office)
    • PreloadedApp.apk (Colorize, etc.)
  • Google applications: (prefer to obtain from Market)
    • Maps.apk (I use brut.all/ownhere versions)
    • Street.apk (has to be uninstalled first to use the above anyway)
    • Talk.apk (old GTalk, replaced with GR4 version)
    • YouTube.apk
  • LG applications:
    • AppAdvisor_v2.0.57_production_signed_aligned.apk (LG App Advisor)
    • SNS.apk (LG's version of social media apps and widgets)
    • OmaDmclient.apk (over-the-air update client)
    • LG RemoteCall (LG's direct remote-control support)
    • lgercui.apk
    • RSstarter.apk
    • RsupInput.apk
    • RsupSrn.apk
    • RsupUInput.apk
    • DM_RsupInput.apk
    • DM_RsupSrn.apk
    • DM_RsupUInput.apk
And I also removed all live wallpapers (except for the live wall paper picker):
  • Bubbles.apk
  • com_lge_christmassnowcity.apk
  • FireworkWallpaper.apk
  • GalaxyWallpaper.apk
  • LiveWallpapers.apk
  • MagneticWallpaper.apk
  • RainyDay2Wallpaper.apk
  • SpaceWallpaper.apk
  • TreeInSnowWallpaper.apk
  • VisualizationWallpapers.apk
  • wdwallpaper.apk
I then added the following APKs (from GR4):
  • SpareParts.apk
  • Superuser.apk (su)
  • VoiceDialer.apk (Google Voice Dialler)
  • Talk2.apk (Google Talk)
Added some UOT battery mods, then proceeded to (re-)install all my apps from Market.

Using Titanium Backup, I only restored my contacts, SMS, messaging data (everything else media-related are all on external SD card and remained untouched through the wipes)... Insofar as I can tell, after a full day of use:
  • battery drain is rather high, but probably because I have everything turned on 24/7 (Wifi, BT, GPS, background social media apps, etc.)
  • very smooth; LG music played doesn't skip/micro-freeze due to other heavy activity
  • YouTube actually (or finally?) works
  • FD bugs haven't reared it's head (yet?)
Thanks Paul, and all the others! I finally have a working O2X! :D

...tasy ROM cooking description...


Thanks for all that! I'll be trying some customisation of V20L myself this weekend and that's a useful post.

Paul has got his hands on a Galaxy Nexus, so he may be spending a bit more time on that than the O2X just nowPosted Image

Speaking of APNs. My list of APNs on my phone is always empty, but I still got phone, data and mms service. Is this normal?
Should I still add the 3 APNs of my carrier? Are they important?
