Call AT&T and get the unlock code.
Say you're going out of the country and it won't work where you're going.

Froyo, yikes. Update to gingerbread with kdz method asap. Froyo is slow and battery drain was diabolical.
Ignore the "no updates" rubbish, that's just your carrier who can't be bothered to give you any.

You are mucking up the forums with questions that have been answered over and over. Please use the search button. I think it's one of the rules (or at least it should be). Everything you need to know is in the dev section. Reading will make you more knowledgeable about your phone, its capabilities and this entire forum.
Good luck rooting your phone and trying new roms.
Sorry i just dont seem to get the right response when i post in right place for some reason. But i will do it from now on.
Thanks i have rooted it now just want decent rom just hard having time to do it with kids n stuff

Good that you have rooted successfully.
21E baseband is the one that doesn't have the :GHOST CALLS" issue.
ROMs are sensitive to the baseband versions, so please be careful about te ROM you are trying out else you will face no network / boot loop / stuck on LG screen.
If you can flash Baseband 21E, then Promethius ROM 1.4 with Promethius Kernel v 1.4.5.1 ( please check for kernel versions with + and without + in the end) will give out the best battery life (as per my experience)
(He seems to be the only one active ROM developer left)
All the best
schubeir
Ive tryed that rom a couple of time twice had no network signal and once stuck on lg screen bloody pain. I thought it was coz i was still running froyo but since on gb still wont work and for sum reason it wont flash the kernals all a bit of a blag for me so just on rooted stock rom now lol
Sent from my LG-P920 using xda premium
You must be on GB and baseband 21e to use latest prometheus roms, and kernels.I think you can use Prometheus 1.3 rom with 1.3 kernel, and you will have signal.

Same here.I was able to run once, and thats it.We shoud send log cat or something to devs...
Sent from my LG-P920 using xda app-developers app
I didn't try it yet but...
Could work if we'll trick the program to think that it's on another device? I mean changing the identity of O3D, as it happens in the Xperia 3D rom by Meemo if I'm not in error. With that ROM the update program and Google Play were seeing my phone as a SE Xperia not as LG O3D!
I'll be peeing against the wind but it worth a shot to try.
So we have to edit build.prop?We need to find the line where device name is i gues...
Will try this...

Looking at my build.prop I see the lines:
ro.product.model=LG-P920
ro.product.brand=lge
ro.product.manufacturer=LGE
Anyway you should see first a build.prop file of a device that you know it works
And pay attention to what you modify because you can brick it, get a boot loop or something like that.
And you should ask advice from a developer... they are all good guys and I think that would help you gladly.
Again I might be peeing against the wind - but you never know.
I did a full backup and then edit build.prop to NEXUS S.With no luck, i got the same error.Will try with different edit in build.prop... Thx for you help.:thumbup:

Thanks.But one stupid question: what version have you tried? I guess the Neon version because ours doesn't have Tegra.But one I've tried Tegra designed games and some of them worked.See my early threads.I'll try also but I'm not so brave with coding or something like that
Sent from my LG-P920 using xda app-developers app
Both versions.None of them working.But one thing that I've noticed is that if you go to kill application and clear cache you'll see that this one, the cache is about 45 Mb which is a lot and therefore freezes the phone.Could this be a problem?Cache file too big?I think that in the end it needs bigger RAM, like 1 Gb.

Well, this has happened to me before and a data/system/cache/dalvik format and then a reflash of CM 10 fixed the problem (IDK why but it did) Assuming you've already tried that I would flash back to a Samsung Official GB or ICS ROM and see if it works then.

INSTRUCTIONS FOR RETURNING TO STOCK SAMSUNG-SGH-T769 OFFICIAL FIRMWARE
So first register at www.sammobile.com, then search SGH-T769 under firmware and download the August 2012 ICS or The Feb 2013 ICS Firmware, wait for the download to finish (took me 30 minutes) then extract which ever firmware zip you downloaded then using Odin click on PDA and select the .md5 file which is located in the extracted ICS Firmware Folder that you've downloaded from sammobile.com
Download the PIT file here
http://forum.xda-developers.com/showthread.php?t=1919228
Click on PIT in Odin and then select the one downloaded from the link above
then make sure re-partition isn't checked and start the flashing process after it is done flashing and reboots you'll have stock ics to root it simply follow the instructions over at the root ics stock thread found here
http://forum.xda-developers.com/showthread.php?t=1919228
This will flash a custom recovery and once the recovery is flashed using Odin reboot into recovery and flash the superuser.zip then you'll have Rooted Stock ICS Firmware
*BOOT LOOP MIGHT OCCUR*
To fix boot looping after flashing stock ICS just boot into stock recovery and wipe data and cache then reboot or on custom recover wipe cache and dalvik cache reboot and you're good to go.

flash oldest custom rom that you find and update after with LG Suport Tool to stock 2.2.2 , that will make your phone stock withaout custom recovery or anything else, download from LG site that tool, and 2.2 or 2.2.1 roms you can find in development, something really old
or downgrade to old bb and upgrade with same LG Suport Tool
I think is safest way
