Once you unlock a phone I don't think you can relock it once again, so no I don't think the phone will re-lock again. Someone correct me if I'm wrong though
Hope this helped!

The phone can be relocked by carrier OTA, but the chances of this being done are zero.
Also to OP. How are you planning on updating your baseband? It cannot be updated except by LG Updater where you flash an entire rom or the KDZ tool, which also requires you to flash an entire rom. Flashing the baseband only is not possible at this time on the P999 version of this phone. Don't use the P990 tool to flash a baseband as the chip is different and you will render your phone a tablet with no radio.

None of the G2X/P999 phone updates will relock it.
The G2X/P999 baseband cannot be changed by itself, it can only be changed by applying the full update which includes the kernel, operating system, baseband, and RIL that is contained in the KDZ file provided by LG or T-Mobile or other cell-phone service provider/carrier and installed through using the official LG Updater or over-the-air (OTA) by T-Mobile, etc. There are posts in the G2X forum with instructions about how to update the G2X/P999, do not use any updater and/or KDZ file for the Optimus 2X/P990. Here's my instructions:

You actually don't have to update the baseband just for that rom there's a zip similar to owains that makes new roms work on the old baseband.... Get it here http://forum.xda-developers.com/showthread.php?t=1714536

Asking help for fellows Brazilians or others Latin Americans users[Baseband and v21e]

Hello all
I was wondering if there is someone that has suceeded in flashing a v21e firmware without getting signal problems here in Brazil.
I am able to flash v21e KDZ and the respective baseband, but I never get signal what is kinda disappointing.
My question is, here in Brazil or other countries with the same baseband we will be stuck on v20a firmwares and v21d? Is there a way to flash v21e firmware without having problems with signal or, in other words, have the phone functionability working?
If someone knows how, please tell me. Thanks

another thing i was wondering if there is a problem with models and v21e
As you know here in Brazil the Optimus 3D model is P920H which is not kind the same as P920 (whole Europe I guess) or P925 (US).
Is because of that i'm facing those problems (no signal) trying to upgrade software version to v21e?

im from venezuela n i flashed v21e... everything seemed to be working right but i noticed that i had signal loss and ghost calls so i went back to v21d and im using cm7 now... still got signal loss but i cant find a better rom atm...
btw i own a p925 latest cm7 nightly

I live in São Paulo and flashed V21E kdz. It always worked on all networks of my TIM subscription (phone, 2G, 3G, SMS). Haven't tried video call yet. Also, wi-fi and bluetooth works well. Soon after this I installed Promethius ROM and kernel and have been using them. This week I travalled to outher cities and noticed that the phone never realized it was on roaming. It kept data connection available even with the option to allow data connection on roaming disabled.

I live in Porto Alegre and had no luck flashing v21e kdz as I said. My carrier is VIVO. I've seen on another post (can't remember wich one to be honest) that someone said that here in Brazil v21e wasn't supposed to get signal at all, but this guy was using it.
As far as I know that could be an kernel issue also, sometimes flashing different kernels could restore signal but i hadn't that luck. I've been using smartflash method to flash v21e baseband (with bin convertor and stuff) because I tought it was a simplier and most effective way to do it (without getting any errors or having to solder a cable properly). Tonight I'll try using Lg Flash Tool like most of ppl to see what happens.
Just wanted to use Acura 3D MAX rom or Prometheus Project... But since i'm stucked with 21d (which i'm using atm) or 20a (original), i'm running ThiaZO3D 2.7 which is awesome but not kind what I was looking for.

Have u tried to flash another versions?
I´m using LGP920-v21e-apr-19-2012 with DNA_GB 3.3.3 with no problems... look into the kdz flash log... post it here... post the About Phone to!

I have a LG-P920H - Optimus 3D.
I had installed a V21e (German) without problem.
None problem with 3G and GSM.

Hmm guys look what I found out.
I`ve tried to install Acura 3D MAX 3 ROM, and guess what? No signal again...
So I was almost giving it up because my baseband was on v21e so I didn`t know what to do.
Then I`ve tried to change the kernel.
I installed bluekernel and it worked just fine...
Why did this happen? Ideas?
Thanks

Hello perna84,
I remember that post, that's why I took more than a month to try v21e. But I soon noticed that in my case it was not true. I flashed the whole kdz using that "marwin" LG application, using the small html server to trick the LG application tool to not update itself. Couldn't find the thread again, but if you need I can try a little harder later. I always used the original usb cable, not a modified one. Never encountered any error message. The original v21e ROM worked fine for the couple of minutes I left it until I flashed custom ROMs.
I tried Promethius ROM and kernel in several versions, but I noticed it to be quite unstable: occasional boots, wi-fi and bluetooth freezes and so on.
Then I tried Acura ROM. Almost perfect but google+ application doesn't work. Other users report other apps not working also.
Now I'm using ThiaiZ v2.8 and, do far, it seems perfect. No misbehaving until now.

New Baseband question (MARCH)

So I've been using G2x with July 15 baseband on canadian mobilicity network(wind variant of g2x)
and it's working pretty good except that MMS doesnt work
However if i want to use new ROMs (Singh UI..etc) I gotta have the new baseband for tmobile...
can I just install the baseband or would it have problem with mobilicity network?
or is it impossible for canadian g2x to get the new baseband update?
thank you

The baseband can't be installed separately with any of the P999 tools and don't use any P990 tools such as smartflash because it will brick your phone's partitions and baseband. The T-Mobile basebands work perfectly on WIND so they should work perfectly on Mobilicity too but you have to flash the .kdz file which will install the baseband, kernel, and ROM then you can install a different kernel and ROM which is compatible with the installed baseband.

No, you can't use CWM to flash the baseband, it won't do it. You must use either the LG updater which won't work for the WIND Optimus 2X because LG didn't supply any updates in Canada or the offline update method for the LG-P999/G2X which will work with a .kdz file.

Did you use the offline update? If you had, that wouldn't have happened because the offline update method uses an http server on your own computer to intercept all of the server communication to the official LG update server and enable updating of the phone which has any version of firmware running on it.

The newset baseband for G2X is 15-3-2012.

I flashed the new March 2012 baseband and now my gps doesn't work anymore. It stays stuck at "searching for gps signal." The thing is I don't remember what I was using before, the March 2012 or July 2011 baseband. I'm assuming July 2011 and the change could've caused this issue. However, shouldn't the new baseband be an improvement on GPS signal and whatnot? Anyways, looking forward to hearing some advice before I try to downgrade back to the March 2011 baseband.

[Q] No 3g After Installing Thiaiz

I installed v21e baseband and Thiaiz over the weekend and I'm really enjoying it, however for some reason I cannot get any 3g connection. My data does work it's just only e or g connection no 3g.

So I reinstalled the official GB update and still have no 3g connection. I believe the problem is with the V21e baseband and not the rom. 3g has not worked since installing V21e on my Rogers LG925. Is there a radio update for Rogers phones? With the Rogers release of GB the ghost calls are brutal so I would rather not go back to using the GB software from Rogers.
I found this thread in the LG Thrill section looks like this user is having the exact same issue.
Any ideas?

ICS working on P920h

I got ICS to work on my P920h (Brazilian carrier - TIM). Here's how:
Download and flash xbsall's ICS using the instructions found here, with the following differences:
On the LG FlashTool Guide link, it says "select only *.bin file" (step 13 from the second post). To make it work on the P920h, you have to select XBSA404_AP.bin from the RAR you just downloaded and V20A_00_LGP920H_CP.fls from the ZIP you can download here.
You can add them both to LG Flash Tool at the same time (in any order). In case it doesn't work, try flashing both of the files from xbsall's RAR and, when completed, flashing just the V20A...fls.
I used the P920h.dll from the page indicated in LG Flash Tool tutorial.
Don't mind the error messages... once you hear the USB disconnected sound from MS Windows, you can detach the cable and turn on your phone.
Thanks to xbsall for porting ICS to P920 and tiagoclc for making the P920h baseband available.
Good luck guys!
According to xbsall, this method will work for rooting. I haven't tried it yet.

Can you please put a walk-through Video. Thanks

I'm from Brazil too, but I have the european version. I got an error when flashing, at about 28%, did yours flash just fine?

Thanks for the heads up. Got it running on my thrill now.... with cell signal... Taking a step down 2 3g put it ok... wifi seem to be real fast... now just need root and cwm... and maybe alittle oc and this phome is golden....

Do you mean the P920 version? Have you used the p920h.dll? If so, maybe that's not the best approach.
Also, I don't know if the Brazilian baseband will work on your device.

HI,
I used the xbsall's .bin and V20A .fls method, didn't worked ... i have the P920H from Vivo - Brazil.
Then i tried Both .fls and .bin from xbsall and then V20A, but i got the same.

I guess Claro's and TIM's networks use the same frequencies... that's why it worked on my phone (TIM).
Have you booted your phone after flashing xbsall's .fls? Maybe you don't need V20A.
If not, you should try to find a Gingerbread baseband compatible with your carrier, in .fls format.

is the v20A the newest for brazil?
im never sure because of ghostcalls
-> strangely v20A baseband is the only one that gives me 3G here in europe,
but i want to avoid ghostcalls, so, does anybody know, if there are newer basebands for brazil/south-america?
i read somewhere that v20A still had ghostcalls back then...

I've been using this baseband since its release (on Gingerbread), and haven't had any ghost calls since.
And with ICS, no ghost calls so far

Yes, I booted my phone after flashing the xbsall's .fls
I Tried both ways , but none worked for me. I'm getting no signal with xbsall's .fls and 20A .fls ... and my old rom was with 20A from vivo

I am also from Brazil. I installed the ICS ROM but my mobile network Claro works only on 2G. Someone could just install the *. fls? I could not, progress is not moving.

Now i got signal ... but i keep losing it every time.

I have p925 thrill but mainly use O3D roms
at&t for my service
usa
could I get ICS working on my phone? i read where thrill users can't keep a signal or get a signal

As it is a beta version, and it was designed for South Korea, we can't guarantee anything. You'll have to try it to see.
I suggest using LGExtract.exe to extract the .fls from a Gingerbread KDZ you know to be working on your phone/carrier (V20A, V21E, whatever). Flash the extracted .fls baseband and see if it works.
