Recently flashed v20p and rooted using the latest ThrillSeeker ROM (love it by the way, great work) but because I use the phone on Tmobile i do not get the 3g/4g access because i don't have the correct baseband.
Before going to v20p, i had simply flashed the o3d v18a GB baseband and rooted with the Acurateam Ginger ROM. With that rom i was getting 3g and 4g speeds consistently with no issues, but for some reason superuser would deny root to ANYTHING that wasnt itself (except adb shell root requests) and i couldn't fix it no matter what i tried, so thats when i went with v20p and lost 3g/4g in the process.
I tried simply reflashing the o3d v18a baseband in hopes it would work, but it just broke reception all together.
So what I'm asking is: Can anyone provide me info on what baseband i can try to flash (with an easier process to do so, if possible) that will let me use the proper bands for tmobile?
I love the ThrillSeeker rom and am afraid to try and convert my phone to an o3d all together by flashing its firmware and roms but i feel that may be the proper thing to do.. but i have no idea if its the same process.

You must not use V20P as is based for the thrill only.
the one I use for my daughter's thrill on t-mobile is V20E

We have found a gb kdz from brazil that works on the LG Thrill. I need some testers to confirm this method works as it works for me. In the end you will end up with a baseband on your phone that works with AT&T fully. You will be able to use the custom european gb roms on your phone. It requires a few more steps to accomplish root.
Requirements:
Being able to flash a kdz like the method described here:
http://forum.xda-developers.com/showthread.php?t=1287236
v20a: The brazil kdz
http://csmg.lgmobile.com/swdata/WEBSW/LGP920H/ABRAML/V20a_00/V20A_00.kdz
v21a: The original euro kdz DO NOT TRY v21b
http://gibtet.net/LGO3D/Roms/V21A_00.kdz
Step one make sure you are on the froyo baseband if not go here:
http://forum.xda-developers.com/showthread.php?t=1343915
I repeat make sure you start on the froyo baseband
Step two flash the v20a kdz following this guide:
http://forum.xda-developers.com/showthread.php?t=1287236
make sure after the flash is successful to reboot into recovery and wipe data aka pull battery reinsert it and hold vol down and hit power
Step three flash the v21a kdz following this guide:
http://forum.xda-developers.com/showthread.php?t=1287236
Step four Root the thrill with v21a installed(only reason for going from v20a to v21a is to root as v20a is not rootable)
After this you can flash any euro gb custom rom or install the cyanogenmod made for the optimus 3d(Do not use the p925 thrill cm because that is made for the froyo baseband)
Please let me know if this works for you.
its not working for me U_U so i need to extract the baseband

There is no known method of extracting the baseband from the kdz. As for it not working are you an lg thrill user? Did you follow all the steps completely?
yes im a LG Thrill user and yes i do it but i do again en some hours but the last time i just get 2G, i hope someone can give us just the baseband.

does the v20a kdz itself give you 3g/4g?
yes with V20a i have 3G/4G and then witg v21a i just have 2G.
so you went from v20a to v21a correct?
yes that correct, when you say in other topic that you keep the baseband, i do the same but without your lucky
Finnaly got it all to load using thw download methed. Ran a speed test on 20 before going to 21. Hit around 1.5 and 21 hit about 2.0. Ao I don't see much differance. And that' about what I was getting here with froyo.

so you have Gingerbread + root + 4G???
In my case with any euro baseband I could never achieve 3g or higher at all. When I went to the brazil rom I could finally get 3g and higher. But for some reason when I went from v20a to v21a I could still get high speed connections.
well i'll try agani in a few hours i hope it works U_U

what is the maximum speed you got
I just ran a test again and hit 2.94 down and 1.04 up. I don't know if that's 4g or not. But it's better than abe with froyo .

now reading slowly i start from Triller rom, not from stock, someonea has start from a custom froyo rom or from that stock rom?
I don't see how it matters
I would think it shouldn't matter if you have a custom rom on your phone or not. both the v20 and v21 don't normally run on the thrill. so the stock rom would kind of be like a custom to begin with.
Cannot get past six percent on update process of the lg mobile tool with v20a. Gets to that point then stops what am i doing wrong
6%
I had the same problem. What I did was in the video at the bottom of the the first link. Leave the phone hooked up to the usb, pull the battery, while holding the vol up and power button, put the battery back in and let it vibrate indicating it's in d/l mode. and restart the update.
it worked but cant see the arrows only see the h and dont have connection
Are u using thrill or p920h?

Guys can I flash an Optimus 3D kdz to my LG Thrill?
I wanted to download the V10K zip and flash it, but it is no longer available to download... But I see some of the kdz are still online, can I flash them with the LG software?
Thanks!
yes you can. I have 20a on my Thrill. You lose your 4g in that case.
http://forum.xda-developers.com/showthread.php?t=1287236
I saw 10k link works.
Why does it loses 4g? In any case, I would still have 3.5g right? My data plan is of 1.5Mbps, so I would still have that right? I am not in the At&t network
when you flash kdz file from Optimus 3D you flash also baseband from O3D,and as the O3D does not have 4g,you lose your 4g.
If you flash 10k,you can flash the Thrill baseband then and re-enable 4g.
But there is no GB baseband for Thill yet,so if you want to install 20x or 21x,you will lose 4g.
I understand that, however my question remains, will I still be able to have my 1.5Mbps without 4g? I think 1.5Mbps is 3.5G!
Also, if I flash 21x, would I be able to return to my original Thrill rom?
You may try.
Yes you will be able to return back to stock.
I'm using the v20a from Brazil and the v21a flashed over it.I'm getting just as good a download as i did with the stock Rom. I've gotten as high as 6.whatever in the mornings when there isn't as much traffic in my area. To as low as .03 in the house. And yes you can go back to stock. Just use cwr and back up before you make anything on it first.

Great! Thanks for the input!
Can someone please tell me what the stock at&t froyo baseband is? I thought it was v10e, but when I flashed that, the phone info said it was a p920. I'm trying to revert from v20p gb.
Never mind, figured out what to do.
And what was that fix?
I am trying to go back to the LG Thrill stock ROM (which worked), but I get no cell service because I believe I am still on the GB baseband. I need to get the Froyo baseband installed.

Flash a V10* KDZ
Sent from my GingerThrilla
Alright, I have the KDZ
Trying to figure out exactly how to make this flash tool work, but I am closer.
Ok I am going to post this because it worked for me several times. If it works for you, great, if not, sorry......I am assuming zero responsibility for bricking your phone ….. So I was thinking there should be a simple way to go back to stock 2.3.5 using just the "LGMobile Support Tool" The problem is that it won’t let you run the update tool if it sees that the operating system version is correct (i.e. running any rom that is 20p based) so what I did was download an O3D rom and placed it on the phone (ThiaiZO3DV2.7.1GB to be exact) I used CWM to install the rom. What this accomplished was to change the OS version but not the baseband. When the rom was loaded and working I turned on debugging and then used the "LGMobile Support Tool">>>(the tool can be downloaded from the LG web site) it will now update the phone to stock 2.3.5 without giving you the message that says your phone is up to date. If you get stuck in a boot loop (as I did ) just pull the battery put it back in and boot into stock recovery using volume down , 3d button and power and just do all the wipes then reboot….I hope this helps someone
Ok,
just to be clear you were coming from the Optimus 3D baseband and rom and successfully flashed to the US Thrill baseband and rom using this method?
I just saw that gingerbread is finally out for the Thrill and thought i'd flash back if there was an easy way. (I have been running the Optimus 3d baseband and defualt rom for quite a while now)

I have never had too many troubles in service but I do notice I almost always have less bars than other At&t users in the same locations
No I was on the Thrill ATT baseband ....... This is just to go back to stock if you are already on US baseband....Sorry I should have been more clear..... Say you were using a custom rom like "AcuraTeam_v.20P" which was made for the thrill, and you wanted to go back to stock 2.3.5 but you didnt have a clockwork mod backup of it on your phone. If you were to try using the "LGMobile Support Tool" it would tell you that your phone was already up to date and didnt need updated. So to get around this without having to use KDZ files to get back to stock 2.3.5 you would install the O3D rom which changes the version number of the operating system which tricks the "LGMobile Support Tool" into going ahead and reloading the phone with the latest ATT update.
Hello there. I am running the official ICS XBSA404 port on my Trill, flashed with the LG tool. I am having some problems (camera is upside down and I have low ram). Phone is rooted without CWM recovery (for some reason it is impossible to install CWM recovery on it, it soft bricks). Can anyone PLEASE help me get back to stock?
Many thanks in advance...

Answering your question, I don't have service with a company in the U,S,A, anymore. Now I'm here just on vacations. I just purchased this Thrill without testing a sim card (I won't pay that expensive roaming from my overseas carrier). I plan to unlock it and use it there.
Thanks for the above link but... will this work on a Thrill (not optimus 3d)? I haven't tried the custom ICS yet, I would like to if it doesn't have those problems with the 3d camera. Can I move from the rooted Official ICS (no CWM) to the custom ICS?

I don't think the 3D camera is fixed on any of the custom ones yet. I haven't checked in a bit, but from the last one I tried it wasn't. You're probably going to have to use CWM or TWRP to flash the custom ICS ROM as well.
The LG Optimus 3D and the the LG Thrill are essentially the same phone. The LG Thrill is the US version of the Optimus 3D. Those instructions will work with your phone. If you would like to install CWM you can use the following instructions to install the recovery.
http://forum.xda-developers.com/showthread.php?t=1859662
The download link is for the .apk file and is best downloaded from your phone, if that is possible. You need to be rooted for this to work. I am using the following ROM on my LG Thrill with excellent service.
http://forum.xda-developers.com/showthread.php?t=1956347
If you decide to use that ROM or one of the other Custom O3D ROMS, you will need a baseband called "LGP920AT-00-V18a-AMA-XXX-OCT-28-2011+0_CP.fls" to work in the US, found here
https://www.dropbox.com/sh/zv3qpd6jylvqg31/9jm_8omNov (Thanks Tactics119)
When you take the phone back overseas, you will need to change the baseband to one that works for your area. You can determine which one you need in this thread.
http://forum.xda-developers.com/showthread.php?t=1958484
You can obtain whichever baseband you choose, from the same place you got the previous one.

Hello. I was wondering when installing one of these basebands would you flash it in cwm?

No. You have to install the baseband and the original ICS port through lg flash tool if you are updating from gingerbread. If you already installed ICS then all you have to do is install the baseband through the same tool. But if you are flashing only the baseband, when it finishes it's going to say invalid ap path. When it tells me this, it flashed my baseband, but it normally has an AP (in this case, ICS) along with the CP (normally the baseband) which is why I think it gives this error message. So you can just restart your phone.
