what i would do in your case is go to the develpoment section and either flash a v20L official gingerbread update (kdz file, you will find an explanation thread how to flash it in there) or download an official froyo rom from original firmware section.
as far as i know you cant flash roms from PC, only basebands/ official updates and so. you need to flash roms through clockworkmod recovery.
concerning CM7 i use nightly builds. they are constantly updated with new stuff/ fixes etc, so its the very latest version of the rom. experimental mod is something you should not care about . and a stable build is basically a nightly that has been picked as a stable build.
cheers

don't use smartflash, it will format you entire data (sdcard internal). better use KDZ since it won't erase you data only system

hello,
wish all here a happy xmas. sorry for my bad english but i hope that i can explain my problem.
I cant find the right firmware in your list.
what i need is a brandingfree firmware. sorry but iam a noob
firmware is 2.3.5
Baseband I9001XXKPF (this what i cant find)
wed-sep-28/KST2011
csc- 9001/XEGKP2
you need more ?
and question is : which custom firmware are pos. ?
hope u can help me
lg marc
You should be able to flash any custom firmware, like Performance Edition RC2 or Cranium Rom. If you want just the stock unbranded firmware, you can flash last one on the list - 2.3.6 XXKPS. I don't know what language are you using on your phone, if it is not English, pay attention to that as well - you'll find all info in relevant threads.
@tomi555,
I flashed the regular 2.3.6 yesterday.with odin very simple and easy. like 10 minutes.
I need a custom firmware a mixed between speed and akku protection.
anybody an idea ??
lg gyver
Well I can recommend you try Performance Edition RC2, it is currenty in beta, you can wait a day or two for the final release. If you are going to install beta, be sure to change CPU governor to smartass v2. Final version will have that enabled by default. It is really fast with good battery life and no bugs (but you can have small issues with installation). You will really see a difference compared to stock rom
Or you can try Cranium rom, but I haven't tested it, seems it currently has a problem if you want to set mp3 as a ringtone. Other than that it seems to be great if you want to overclock your CPU. I don't have such needs so I'm not using it.
thx tomi
ok I have the rc4 now. but how I can update to rc6 or rc5 ?? Is it pos. to run rc6 on my i9001 ??
pls help
thx gyver
You mean Cranium RC6, of course it is possible, you can download the Odin one package from their website.

For other questions, info and installation tips check out its thread.
http://forum.xda-developers.com/showthread.php?t=1313650
thx soooo much.
I used this thread to flash to rc4.
Installation:
Installation for RC6(comin' up)
*Recovery Package (Now,easy to install!)
1)Install FeaMod Recovery
2)boot into recovery mode
3)Flash Cranium Rom
4)dont wipe cache.............and fix permssions!
thats all for update up to rc6 ???
lg gyver
Yes, I believe that's the method if you downloaded
Cranium Rom RC6 (CWM Version)
You can flash it via Odin MultiDownloader from your computer just like the stock rom if you download
Cranium Rom RC6 (Odin Version by nikagl)
But... like I said I don't have that ROM so perhaps better double-check / ask in that thread
I dont know how I can install Feamod Recovery.
If I have it to flash with odin ?? where is the ariesve file ?
or can I use the same as to flash the rom ?
lg gyver
got it.
damn this is very cool. thx to the hole xda team.
@tom special thx to u

My optimus is on order (best i could get through work!).
The idea is to flash Root - Flash CM7 and have a nice speedy phone
Seems the steps are quite easy
- Root
- Install Rommanager
- Flash CLK recovery
and install a rom the usual way (format - flash zip - go go)
I'm a bit confused atm - seems there are CM7 nightlies which haven't been updated and 2 alternative CM7 versions in the android development subsection.
Was thinking about trying the
temasek's KANG BUILD + CM7 Kang kernel
Looking for vanilla CM7 really - used it on a desire S (got stolen..) and an HD2 (temporary device).
Most of all i'd like ICS but seems the optimus 2x isn't that far yet
There are indeed two cm kangs in the dev section, from Temasek and koboltzz. So you can choose between them. Also, these kangs are far better than the official cm nighties and the latest stable. So, in fact you can choose between the two, or official cm of course.
Sent from my LG-Stone from the Prehistory....
Naaaahh... Just kidding!
CM7.2 Temasek KANG P204-30
Ironkernel (Vadonkas KANG)
You should use the latest Temasek kang imo, these are kangs more up-to-date because the normal CM7-nightlies are not going to be updated anymore. (before ICS)
I have used almost every single rom on XDA on my Optimus 2X, and I must say that the temasek kang (i'm at build 27) + Vadonka's kang kernel is the best combination I have had so far. It's super-smooth, stable and amazingly fast. Compared to the stock LG-firmwares it is a very noticable difference, especially because stock LG-roms have serious memory leak issues which causes huge slowdown after using your phone for a few days without rebooting. (this is very annoying)
CM7 is also much faster with browsing, the stock browser on CM7 is a lot faster than the android browser on LG's roms. (don't know why). Moreover the multi-tasking with latest CM7 kang+vadonka kernel is very good, memory management is excellent.
You should also look at the Baseband (BB) that you have on your O2X. You could update your O2X with LG's updater, which updates to 725 Baseband
You should remember: Cyanogenmod7 (CM7) does not change or flash your baseband. RIL and BB are different, CM7 only contains a RIL, which is a small part of the firmware that can easily be changed by using the Android App GetRil from the market. Most of the time a matching RIL-BB is the best. ( So BB 725 with RIL 725). All CM7 roms contain the RIL 218 so you might need to update your RIL with the GetRil app (1 minute, very easy app)
It's recommended to use baseband 725 with RIL 725 or RIL 218 (both seem to work fine, you should try by yourself)
It seems like you are already experienced enough, to flash your O2X, it's not very difficult.(optional:update to latest LG rom for latest Baseband)
Then: Root(see post on this forum, oneclickroot etc. doesn't work). This method also includes ClockWorkMod recovery, so all you need to do after this is copying the CM7 Kang (+kernel if you want) to your Phone, reboot into recovery and flash.
Both kangs are quite good, and I don´t know if u wanna consider miui, but I like it quite a lot. u might wanna check out vadonka´s o ironkernel with those. the first one has a little more battery life.
No miui for me
Thanks for the information!
Lets hope we get Tegra2 ICS drivers fast! Flashed a beta on my current HD2 and i really like it!
Could only get 1ghz singlecores which do have ICS beta's or this Optimus 2x which has a dualcore and a far more powerfull GPU - lets hope the gamble pays off

Hello!
Latest version of SuperOneClick should work...
http://shortfuse.org/
But it isn't a big advantage over the linked method as posted by TrymHansen, since he needs to install CWM anyway...

Aha sorry, good to know
if you want to use CM7 then you should flash the kang either temasek one or koboltz up to you. since CM7 doesn't release the nightly, maybe they just release straight to CM9 don't know.
but there is still another rom such as miui, and stock rom which is already tweaked and there are many kernels for this phone both for stock and CM and miui
see the development section and happy flashing
I think MIUI ROMs are great!
You should also check out wajk's MIUI ROM. Its really great!

SuperOneclick (latest) worked only kinda for me.
It did in fact root the phone but only until reboot.
It did however give me the chance to install CWM and then CM7.
But if you're using SuperOneClick then it doesn't matter. I mean just install CM7 straight off and then have CM7 flash CWM.
That's how I did it the second time and it felt like the easiest way.

just use any guide, and it should work fine
Where can I get the latest Official Gingerbread ROM?
Either from B2C (LG Update Tool) or you grab the kdz (google for it, or search the forum) and use R&D tool plus workaround to flash it (see in my noob how to )
What about those? Can I istall them using ROM manager?
and whick version is the latest?
http://get.cm/?device=p970
Yeah you can, but they are buggy, but that's your own choice, read the CM discussion thread about it. The latest is the one on top
Cm buggy? Even Zeus rom has bugs... let the man choose for himself. For me cm is by far better than Zeus or other cooked rom. But that is just my point of view, test a lot of roms, then choose whatever you want.
Remember when flashing a new rom do data wipes and cache wipes.
Trolling in the deep
Hi guys, just bought an O2X yesterday and I want to be sure of the steps on how to take my Froyo to CM7 or any other GB for that matter, so here's what I think it should be done:
1.- Root the phone (seems Gingerbreak works on this phone with froyo?)
2.- Install CWM (Can install from ROM manager unless I wanna be able to flash from internal memory in which case I should install the modded vesion?)
3.-Change baseband?? (this is my biggest concern, I'm on 1035.21)
4.- Flash rom + gapps if needed
Please guys if you can confirm my thoughts on all the 4 steps it'd be much appreciated
_BONUS QUESTION_
Is the hdmi and camera working completely or is the stock froyo better on those aspects, as I don't see a thread for official CM7 I'm guessing I should just download from download.cyanogenmod.com/?device=p990 ?
Thanks again.

You are almost right there m friend.
There is an unofficial CM7 thread out there by Temasek and MisjudgedTwat....it is more than what you can ever see.For CM7 ROMs, choose Kernels by Temasek or by MisjudgedTwat or by Vadonka.
If you are looking at Stock based ROMs, then go for DjangoManouche1.3 beta16. Stock based ROMs + HP or Gueste Kernels.
for the Baseband,you have to come out with the full version number ...what you have mentioned is not complete.Try V20Q for the BB with V10 series RIL...Normally, CM7 comes with a RIL which is enough. Install GetRIL app from the play store and you can change RIL if it is not compatible. For the Stock based ROMs, you can flash the V20Q Base band + v20Q RIL(both are 725 stuff)

Thanks a lot for taking the time to answer. Now the baseband thing got me a little confused, if I go for official CM7 which will come with a RIL I'd have to install a matching baseband. Can I do that afterwards or do I have to change the baseband first?. I remember with my O1 I flashed a rom and got no service because I was on wrong bb, and flashing the bb fixed it. I just wanna be sure it's fixeable if I mess up
btw.

Look at this thread...it has all the BB related things.You can flash the BB which is V20Q which is the latest for O2X (your choice as it is the service provider,region,device and so on)and this is the best as you will see in the thread which has a poll. you can then flash the ROM with the three wipes...dalvik,user data and cache.Dont forget to backup your apps and data with Titanium Backup pro or any other app.
http://forum.xda-developers.com/showthread.php?t=1658047
you can then use the GetRIL app to choose your RIL...which is normally with the ROM.Best way would be flash the BB and then flash the ROM(to save time). Flashing the BB will wipe the complete data. Take a backup through CWM before.even if ou have an issues with wifi,mobile data 3G, dont worry to choose the correct RIL and reboot.
if you have any issues, wipe the three wipes and reflash the ROM.normally, you wont have any issues....just do it...
I am only trying to help...dont blame me for bricking ur phone...follow instructions and we all have a great device...YOU WILL TOO

Thanks again man, I've a better idea now. I'll keep using my phone with stock rom for a week to have something to compare to and then go crazy trying roms
I know everything I do with my phone is my full responsibility so no worries there.
Thanks!
Sorry if this was posted, but i didn't find it.
