Hi,
I have been looking through various custom roms for optimus 2x and intend to install one very soon. Before installing i have some questions
1. What is baseband? How do i know which one to use?
2. What is the best/recommended steps to install a custom rom? I know what you have to do before installing a custom rom, what i meant is the order in which you should install custom rom, kernel, some performance packs and baseband, etc.
3. What do you look for in a rom before deciding to install one?
And finally, how can i help the development community?
1. baseband is the software for radio in the phone. You dont have to flash new, you can keep on you baseband from original rom, its not flashed automatically when you flash custom roms by clockworkmod. you only need to download lg getril for example from market and install matching rill to your baseband.
2.
step1: root phone
step2: instal clockworkmod
step3: download zip file with rom to your sdcard
step3: power off phone, then hold volume down + pover on(first volume button) until the clockworkmod starts
step4: backup phone in CWM
step5: every thread with custom rom have the manual how to flash in cwm, its easy.
You can read about it on modaco optimus 2x forum. Lets google it.
There are basically two types of rom for O2X, the one is based on the modified stock rom. the second one is cyanogenmod based rom, i like the cyanogenmod.
You should use matching kernel to type of rom(cyanogenomd, based on ofiicial), kernel is closer to handle hardware, i can imagine it like kernel is between hardware and ROM, ROM is between kernel and user.
3. you should try some ROMs and decide what you like.
EDIT
4. sorry for my bad english.
Your baseband is visible in Settings/About Phone. Try first to flash without changing it. Get the matching Ril with GetRil or LG Ril version in market.
To root you can use latest Superoneclick (see thread in dev section, it seems now to work with GB a well) or nvflash method (see rooting for dummies in dev section).
In the first case you instal cwm with ROM Manager from market, or your can flash it directly using Rusty!'s build (see stickies thread in dev section).
Nothing else to add to the above post. Two families of ROM as said, all coming from stock LG are based on 20L/M/O original ROM. Others are either cyanogen (see in Kang thread, as nightlies build bot is out of order for now) direct, or cyanogen derived (Miui).
Read carefully first posts in each ROM thread, and be sure to have always a back up.
Thanks tomsi91 and Striatum.

Your sig says : O2X Topogigi SP3 ROM upgraded to 20M - Horse Power 2x Kernel RC11 + Swap/Power Pack 9 lite - Ext4 - BB & RIL 0725 (V20L)
I wanted to know the order in which you installed it. Did you install the kernel first then added the rom or did you flashed the rom first then flashed kernel and the others in the order written in your sig
TIA
A bit of topic but anyways, my BB and RIL don't match so
1. If I match them what improvement would I have?
2. Do I really need to do it even if I am not having issues with call quality?

No reason to flash kernel first it will be overwritten by ROM.
ROMs are always coming with a kernel!
First: ROM. A good thing is to boot then, and follow the First Run Configuration Wizard.
Second: Flash Kernel of your choice.
Third Power Pack if you want, mandatory with SPica's kernels to have all features.

No Problem = No change.
Golden Rule.
just to add.. don't forget to back up your messages/app data/whatnot with titanium backup or whatever
also note that a lot of the LG system apps will obviously be gone when going to CM7 for eg:
the camera for one thing has it's pros and cons. a lot of people seem to prefer the stock camera
the music player doesn't have a cool landscape mode
fm radio is **** with only 6 presets
sound recorder doesn't let you change quality
no built in memo pad (but you can always get one from the market anyway)
and the LG widgets (i like their weather and calendar widget)
"backup and restore" app which was quite useful (i believe it's made by Sprite).. but no worries since there's titanium anyway
although perhaps these system apps are backup-able as an apk in titanium?
Stock LG apps can effectively be backed up as apk, but they can't be run on CyanogenMod, so no interest.
I bought 2x 3 days ago. The lg gingerbread is fine. But not that impressive. I want to root it but the problem is rooting, voids your warranty. Is there is any way so that you can backup the android os given default (by lg), so that you can install it later to claim ur warranty later on. And is there is anything else? to do please correct me.
1. Backup your phone content(contacts, msgs etc)
2. Backup your factory installed OS (I don't know. how to do that).
3. Root your phone by some rooting software(superoneclick,etc).
4. Flash new cm7 rom or any custom mod.
5. Done? please correct me if i'm wrong.

Baseband can't be changed with cwm. Only smartflash. And a custom ROM always come with a kernel or it can't boot...
Better to go back to ext3, in case the new ROM doesn't format. And to be sure no residual file will be left and not overwritten, that could cause troubles.

Is there a newer basaband than 1035.21_20110725? This version is the same in all latest stock ROMS (V10D, V20L, V20M). Flashing the V20M (with smartflash) will have a different baseband although it will say 1035.21_20110725? I installed the leaked V20o but I have problems with signal loss after some hours in stand-by.

It's one of numerous LG inconsistencies... Different BB with same number.
It seems in fact they are not the same. Try different Rils with GetRil, the 20o one but also the 20l etc...

I did try different RIL when I had the V20o. I changed the RIL V20o Europe to V20L Italia which I had with V20M update which I did through LG official update. Do you think flashing V20M with smartflash and then installing the V20o will fix the problem?
Thanks
Hi chaps,
I just managed to brick my TG01 trying to get WP7 on it (can't believe it, have flashed endless WM ROM's and had Android running on as well without issue :-( )... so I have done a bit of a knee jerk and quickly bought an LG Optimus 2X to play with until I can figure out how/if I can fix the TG01.
Obviously I've read reviews and seen feedback, and hoping I don't get a dodgy one.. but I've bought my brand new sim free for £199 from Amazon so should give me some protection if it's broken.
Any tips other than doing the 2.3 update ASAP? (until ICS official comes out)
Root it and flash a custom rom!
Stock rom sucks really, really! It's slow, buggy etc. Also, don't download the OTA update, because froyo is easier to root with Superoneclick.

Will rooting and flashing a custom rom stop me from upgrading to the official ICS later?

I think temasek's CyanogenMod KANG is the best rom available, especially combined with Vadonkas KANG kernel.
Temasek's KANGs:

Vadonkas KANG kernel:
http://forum.xda-developers.com/showthread.php?t=1427646
If you root it and flash CM on it, you'll obviously won't be able to get the official ICS update. But the truth is, LG is so 'great' that you likely have to wait until next year to get the next OTA. So the best thing is to root. Also, in a few weeks hopefully, CM9 will come out which is based on ICS.
I believe that you can find those apps in the market.

A tip? Buy a Noreve Leather flip for it .. they rule
Aside from that: Can I just flash the newest temasek KANG (what does KANG stand for anyway?) and the newest KANG kernel you mentioned? Or do they have dependencies that could brick the P990? And what about the other business (rils and whatnot?).
And is it as simple as rooting it (I managed with Superoneclick with the latest OTA), installing rom manager, let rom manager install cwm (will that work? I also see temasek has a KANG CWM folder in this repository), boot into cwm, wipe everything and flash the temasek rom, and after than, repeat the same with a kernel zip?
The dependencies and sequences confuse me most. On the DHD I put ICS on, the ROM came with a working kernel. But in that Temsake KANG thread it says:
"Flashable zip for Stock CM Kernel with Voodoo Sound - for p990 only (Optional)"
For a CM kernel? So do I need this installed first somehow? All very confusing for newbies to flashing like me...

The latest temasek KANG with Vadonkas KANG kernel won't brick your phone. Many people use this combination and no one has bricked their phone so far.
A great CM KANG is nothing else but a CM rom but then developed by developers outside Cyanogen Team. They use Cyanogens source code and improve or change it anyway they want. KANGs are also more stable than normal nightlies.
So Vadonkas KANG kernel is just a kernel he improved/changed using source codes from others.
Note that temasek's kang standard comes with 218 RIL. You can change this manually with the GetRIL app. Basically you don't have to change the bb. Also, Vadonkas KANG kernel comes with voodoo sound so don't worry about that.
Then flashing:
1. Reboot into recovery
2. Backup rom
3. Wipe everything.
4. Flash rom.
5. Flash kernel
6. Flash Google Apps
7. Done, reboot.
If you come from cm, then you don't need to wipe everything, just cache and dalvik. Also, if you want to update your kang rom (temasek), you can just flash it over your previous rom.

Thanks .. again "Boot into recovery" means I have to install CWM with rom manager first? I never installed CWM, so I'm not quite sure about that (on the DHD, the rooting ace hack thing did install that asfaik). And which gapps zip do I have to flash?
And maybe something about the RIL: I have no idea what it is. All I realize is, that it somehow has to match the kernel? or the hardware version? Or your area? I'm a bit confused on that as well, sorry.
EDIT: Ok ... Radio Interface Layer. A driver to the hardware's radio hardware? But that's static, so why all the various versions?

Haha no problem.
Yes you need to install CWM with rom manager first, preferably the most recent one.
Just the latest Gapps, you'll find them in the CyanogenMod wiki.
RIL has to match with your baseband so you'll have the best possible signal and minimal battery loss. The reason for al those versions is because of the fact that most countries have its own RIL. The app wil notify you if your bb and ril match. If not, flash another, if so, keep it that way .
Note: when you're coming from stock rom you need to wipe everything so also make titanium backup, just in case...

Hm ... okay ... CWM is on it, done from Rom Manager, selected the LGE Optimus "x.... booted into it ... but it says it can not mount my SDCARD (large 32 GB thing, which works inside Android .. but oiccasionally seems to behave a bit difficult.).
EDIT: Trying another SDCARD now ... an old Samsung 8 GB. Hm nope ... it can't mount that 8 GB card, either They're just ordinary FAT32 formatted cards. Guess I'm stuck for now. Could there be something wrong with the CWM Version? Rom Manager did ask about the model, but I selected the correct one I assume.
EDIT2: It seems ROM Manager is not really flashing cwm? And that booting into it from Rom Manager causes the SDCARD moutn isssue due to soemthing called "redirector"? I tried getting into CWM by all kinds of fingerpress combinations I read about ... but nothing seems to work so far.
EDIT3: Seems working now ... Power + Volume Down ... like HBoot. It also sees the sdcard now, if you directly boot into it ... let's continue this journey....
EDIT4: Arrived. Tamasek ROM + Lower Power Kernel + Gapps. Now to find out what's better than stock ROM
For those not comfortable with flashing custom rom, flashing a custom kernel may be good enough. I am using Horsepower SR2 with stock rom, took away many useless apps with root uninstaller, it is so much more damn smooth then the original, more responsive too. Played Need For Speed those kind of games, totally no lag.

Excellent... picking up some ideas already (like being able to just flash a new kernel for example ) Might do that as don't want to lose functionality.
Whatever I do I will use it at stock for a week or so, to check the phone is stable (I will probably update to latest software from LG first though to be honest).
I have also ordered a 3500mah extended battery and case cover. £4.99. Something tells me it's going to be cack, but thought i'd give it a go (I've read about the whole battery calibration thing and needing to be rooted etc, so I'll ask about that at a later time). I just was not going to pay something like £75 for a mugen 4500mah battery that was even bigger. I believe mugen could easily fit three battery in parallel (including circuitry) in a 'T' shape to give the phone a thinner profile with a bigger battery. If I was able to get a battery cover that was a little bigger and fit, I would give it a go (I've wired a fair few batteries up recently). But I digress..

That's probably the worst you can do to check if your phone is stable LG ROMs were known to boot themselves etc, although I'm not sure if this still is the case. I didn't lose any functionality with flashing and it runs smooth as a baby tush. There's even a kernel using less power etc ...

lol @ the "worst thing you can do" comment
What I meant is.. see if the phone has any problems, and see how it runs in general. I doubt LG would replace a phone with an alternative ROM if it goes wrong.
Also, without a baseline I can't determine how good an alternative ROM is. Also, with alternative ROM's on the TG01, I lost things such as being able to send/receive MMS's for some bizarre reason, and I see people saying things like "this app doesn't run, but does on stock", "no 3G vid calling on non-stock ROM"... so it's not as clean cut as you make out. I'm no stranger to hacking things about to get them to work, I'm a Dev in my job
Appreciate the advice guys, thank you

Well... it has arrived :-D Trying to decide whether to turn it on before attempting to fix my TG01, as the battery charger arrived today as well lol.
EDIT: By the way.. I have just plugged it in to do a long first charge. Is it ok to turn it on whilst it's charging and play with it? lol Also.. it's a "Made in Korea" version, not sure if that matters?
Update: Well, I've updated my phone with 2.3.4 from the official site. And so far, I'm really liking the phone Everything is super smooth, the screen is nice, and the battery life seems good so far. I only lost 5% battery last night over about 7 hours, and that's on the stock rom with the battery not calibrated on anything fancy being done, and 3g/data still on etc.
'So far' it seems like a solid phone Really don't like the way the back cover comes on an off though, that is a really poor design.
I have not followed to update rom for my device for a half year
So I don't know what is the best rom for Optimus 2X now
I am using CM7 and I feel like I like it, I get used to it.
So that's why I am looking for only CM7 rom.
However, if you have any other rom that you think it's better. Please suggest me, and please tell me why is it better.
Thank you.
this is my device information
Android version: 2.3.4
Baseband version: 1035.21_20110405
Kernel Version: 2.6.32.41-vorkKernel
Mod version: CyanogenMod-7-06212011-NIGHTLY-Optimus2X
Any of them I need to change for a better performance, please tell me.
ps. I suffer the freeze problem sometimes. For now, I use it only for game and chat. When I play a game, I usually suffer that the game hangs, and popup "Force Close"
And sometimes phone automatically shut off.
I was bored, until I feel nothing about it...... (too often until I buy new phone to use as phone, and use 2X as a video game device)
Look for temasek's Kang rom in the Development forum. It's quite stable, has a great performance and battery life is good too.

You might also want to change your kernel. Vorkkernel is outdated, try either ETaNa Kernel or Ironkernel. You should be able to find them in the dev section.
yeah, I know that my rom and anything of that is really old because of I play lots of game and don't want anything to be erased. Also, that time the new rom update too fast. I was bored of changing rom every 3 days. So I stopped following all of these and keep using it.
And now, I think the time has come to modify everything.
Can you guys tell me the best version of everything for me to upgrade it.
e.g. Firmware (my 2x is still V10B)
Baseband
Kernel
and Rom
if you specify version for me, it would be much faster for me to find it
thank you
Allright,
Firmware: Either Android 2.3.X or 4.0 (your choice, however 4.0 is still in alpha phase, so not everything is working perfectly)
Baseband: Different for each and every phone. Do you have good signal and call quality right now? Then there is no need to change your baseband. Make sure to have a matching RIL file with your BB. Download one from the GetRIL app.
Rom: For Android 2.3.X (a.k.a Gingerbread) I would recommend temasek's latest CM7 KANG, or the latest CM7 nightlies, because they are the best and most recent. Temasek can't continue his CM7 work anymore unfortunately, but his Kangs are rock-solid. (Link in signature)
For Android 4.0 (a.k.a Ice Cream Sandwich) you can choose between the latest RC'S CM9 SelfKANG (link in signature) or Owain's CM9 KANG. (dev section) They're both pretty new and are quite stable despite being in an alpha stage. However, not everything is working perfectly, but I can tell you once everything works, CM9 will be much better than CM7.
Kernel: If you use CM7, you can choose between many kernels. The best ones I would recommend are the ETaNa Kernel (link in signature) and Ironkernel. These kernels are the most recent and have the best performance. Unfortunately the dev from Ironkernel, SetIron, left XDA so you cant follow the development over here.
For CM9 there is only one custom kernel available, which is also Ironkernel from SetIron. (link in signature) Although I must say that it's not fully stable because CM9 being in an alpha stage.
Hope this helped
For me, temasek's latest CM7 KANG is the best ROM so far.
However, seeing you havent change ur ROM for the last 6 months and familiar with nightlies, I would recommend you to update to the latest CM7 nightlies.
Just as simple as that. no need to think and you will find your O2X in its best performance.
I recommend Temasek's Kang. I started using is a few weeks ago and it's the best GB rom I've used. I'd still be on it, if I hadn't tried CM9.
thank you all you guys, I will try it soon.

I am new to android hacking. I am using CM7 on O2X as of now.
I have few queries if you could answer, I know they may be very modest, but still they are unclear to me if you could help
What is the difference between ROM/ Kernel/ Baseband?
If I apply a custom ROM will it change Kernel and Baseband too?
I did a nandroid backup before installing a custom ROM, but when I restore it, it doesn’t work the screen keep on flashing and nothing happens. Can you suggest something here?
Rom is like the OS, like froyo, gingerbread, cyanogenmod.
Kernel is like a bunch of drivers and sets of ways to execute those stuff by the OS.
I forgot about basebands and RILs.
Changing rom means changing everything but baseband & ril. The exeption would be temasek's cm7 kangs. He include 218 ril with his kangs. Kang is when you compile cm roms yourself and you can share it freely to people.
If restoring a nandroid backup didnt work, you probably restored it from a different version of cwm recovery. Maybe, you made the backup from version 4xxx and restored it over version 5xxx, vice versa.

I have few queries if you could answer, I know they may be very modest, but still they are unclear to me if you could help
What is the difference between ROM/ Kernel/ Baseband?
If I apply a custom ROM will it change Kernel and Baseband too?
I did a nandroid backup before installing a custom ROM, but when I restore it, it doesn’t work the screen keep on flashing and nothing happens. Can you suggest something here?

There is no reason to change your baseband. Simply flash the rom you want, flash the kernel you want (if not included in the rom), download 'getril' from the market, use it to match baseband and ril... that's it.

Getril doesn't work in my P990h, although LG ril appears show that there is no problem with my baseband and ril.

but i still confuse. I was 100% sure changing rom was going to change baseband, kernel, etc.
Even after this post above i still confuse.
It is aways the same:
First root, then
1 baseband
2 rom
3 matching ril
4 change kernel
?
in my case the problema is the signal. I lost signal with frequency. Should a try only Baseband and then mathing ril?

When you flash a ROM everything is changed except for the baseband. The baseband sticks to your device no matter what ROM you're using. The only way to change it is using either Smartflash or nvflash.
What is the best Baseband / RIL combination? No one can answer that as each one of us is on a different mobile network with different settings and on different countries, so it's up to you to try and find out which is the best baseband / RIL for you.
By the way, flashing a new baseband will wipe out everything. Make sure you create a backup first.
Hope this clears things a bit for you now

Which baseband is the best?
The classic question. Unfortunately there is no good answer as this depends on your phones specific hardware, your carrier, your reception, your network, the universe and so on.
People with phones "Made in Korea" (you can see that on a sticker under your battery) usually have a better experience with SU660 Basebands. Apperantly the phones have some SU660 hardware parts inside.
Some people won't even get a connection with a specific baseband while others consider it the best.
You have to try for yourself!

my reception is horrible, that is the reason i am trying to change rom, bb, etc.
that is not the first time i read totally divergent information, so i am asking before brick my smarthphone.
the jargon used to change rom, bb in Android is totally new for me. I am reading the foruns i see people with exactly the same problem i have. But i see that aftfer ask 1, 2 times the person give up.
Was a total surprise for me that chaging the BB could wipe system data.
Looks like when i post in a dedicated thread people send me to the general Q&A, but when i ask questions in the Q&A, people send me to the dedicated threads even if i don't know wich are the steps and wich tools i should use to achieve what i want:
safely try the faster rom and solve the reception/signal problem.
Your reception problems may not have anything to do with your bb/ril. It could be that you simply have bad reception due to your location, carrier, etc. If you had bad reception with the stock rom, changing to a custom rom is probably not going to fix it.
If you just want a faster rom, then I think you should install the latest Nova HD v. 1.0.1.(http://forum.xda-developers.com/showthread.php?t=1508492). Then use the custom installation option to experiment with different rils, different kernels etc. to find the best combination for you overall - and you don't have to do a full wipe every time once you are on an ICS ROM. Taking a backup of your rom with CWM is always a good idea though, just in case. You will not brick your phone as long as you follow the instructions given. It is actually pretty hard to brick your phone!
I use too Nova HD ir very smooth And a lot battery life.

Simply try different BB / RILs combinations (eg. BB420 and 420 RIL). You don't really need to use a matching RIL with your BB, but it is recommended. If you find a BB/RIL combination that gives you stable signal and data, then stick to it. That's how we do it.

Your data partition will be wiped out while flashing a new baseband. That is why you should get a backup first so you can get everything back later.

Tonyp's post has all the info you need regarding this. Third post contains info on how to flash a baseband and the tools you need for that.
All the info you'll ever need is likely to be already posted somewhere in the forums. If it's not, you can always open a new thread and ask (but remember to use the Search first!).

http://forum.xda-developers.com/showthread.php?t=1035041
2- If i am planing to change bb too, should i change it (bb) first then change rom?
Thanks
Bb will wipe your os. So yes... bb 1st then rom.

Losing baseband
Hi guys, I'm new here. So I flashed my Nova HD Rebuild v1.0.3 recently. Then I flashed the kernel to Spica's hp kernel. ''[SuperSonic]*[April-05]*[CM9-ICS KERNEL][RC1-R] Horse Power 2x ICS RC1-R [OTF'' This one. After that, my baseband became unknown. I restored a cwm backup and the kernel changed back to the stock nova kernal. But my baseband remained unknown.. I've searched a lot on the forum and really couldn't find anything similar to my situation.. Any help guys?

Hi Arthur, take a look here. You'll find there how to fix that
I am new to this forum,so first let me introduce myself.I am a doctor in india.
I bought this phone last year and like most users i was really disappointed with it. Intially it was froyo and then with extreme difficulty I updated to lg stock Gingerbread using its update too.I think the tool itself was buggy like most lg stock ROMs.
Anyway updating to gingerbread was a bad experiance .Too much lag in doing even basic phone use ,forget a smart phone experiance.Anyway not explaining in detail all the problems ,we all know it.
Was waiting for Official ICS release,so never thought of Unofficial ROMS since wud have made it difficult to update to stock ICS by company.
But last weak finally decided to try CM based ROMS and after some research decided to try Temasek CM7 based unofficial ROM build 132,
I must say what an experiance I had.From awesome to wow ,i am short of words to describe it .
So here i must thank everyone involved with XDA and especially cynogenmod and Temasek in perticular.
Thank you Temasek
Thank you XDA
Thank you cynogenmod
You all have made this ****ty phone into a delight to use .
I have installed " n " no of applications and still there is no lag and there is no shortage of RAM(and LAG due to IT) even after i week of using it ,which i used to have with stock gingerbread.
I must say i had been a noob and XDA and all you developers have made me into a mobile phone expert rooter ,flasher, etc.
I had few issues which i wud like to discuss,thanks in advance to anyone who helps me solve these.
I had flashed temasek CM7 build 132.and I had thought it wud also flash latest temasek kernel but it seems it didn't.
It now has kernal version [email protected] # 1
Mod version CM7-20120809
I basically want
1.A kernel with voodoo sound support
2.Ramhack
3.Good battery performance with 3G on.
4.Camera mod if possible.
Temesek could you give a small tutorial on variour kernels made by you,I looked various log changes made by you on p990 kernels but i am very confused.
Also what is difference b/w OC and uv etc
I have spent two days installing various applications on your ROM, so obviously will not like to do factory reset,data reset ,cache reset etc
before flashing any new kernel made by you.Kindly provide some suggestions on what i shud do.
Symbiosis kernel looks promising too but again don't want to wipe anything basically reinstalling all applications all over again.Any suggestions.
And yes I am sure you people in XDA wud soon release a fully functional ICS and even a jellybean based ROMS.So Now with my experiance i can say dont eeven want a LG stock ICS or jellybean even if they release it,untill then I wud stick to this wonderfull ROM by temasek
Thanks everyone and all the best to developers in their efforts on developing a fully functional ICS /jellybean based ROM.Hope to see it soon.
Hi if you already have temasek ROM installed on your phone you can flash latest symbi0sis kernel 1.1.2 without loosing any data! just flash the kernel via cwm and boot the phone - done
also symbi0sis is based on temasek kernel, works perfectly with temaseks ROM
after kernel install u can open the app GuesteOC and enable the ramhack with your preferred size in MB

Thanks for quick reply stefan.
So does that mean i dont need to do data/factory reset or cache reset before flashing symbiosis kernel or any other kernal .I have tons of app's installed ,don't you there can be bugs if i dont do a factory/cache reset before flashing symbiosis kernel.Its written in most threads that kernel flashing is similar to ROM flashing ,so data/ cache rest is advisable.
Where can i find GuesteOC app or can i use terminal emulator method as described in some threads

Np just flash the kernel without any wipes. it will wipe dalvik cache automatically. i guarantee you it won`t break your apps.
GuesteOC is included and will be installed automatically. no need for command line, everything as simple as possible with symbi0sis kernel!
if you try other kernels you might need to wipe dalvik cache first if they dont do automatically!
also u can do a backup in cwm first so if something goes wrong you restore the backup with all your apps.
Thanks stefan i will apply your Kernel today itself.Hope it solves everything ,Voodoo sound support ( i have the app with me) ramhack and good battery life too.Will post back if i face any issue.and offcourse my compliments
Also another question to you .You have said CWM backup/Restore .I did the same 3 days back before installing temasek ROM.But had forgotten to keep backup of some important SMS messages so tried to restore original stock LG ROM through CWM back up/and restore.
I Had a real shock it said that i had restored everything but my LG started rebooting again and again just stops at LG logo everytime.Even recoery was not accessible.So i had a torrid time going through variuos XDA thread .NVflashed stock froyo ROM and then flashed temasek ROM.
The only thing i missed was that i pressed backup/and restore straight from CWM app instead of going through manual recovery doing data/cache wipe and then restoring from Backup image.
Can you through some light on the serious issue that i had

Maybe it had to do with different file system (ext3 stock / ext4 temasek) -- afaik you need to flash back2ext3 or something when you want to go back to original stock ROM. However I have never done that (going back to orig stock). Next time best use "SMS Backup & Restore" (available in market) for backing up and restoring SMS after ROM change!
Good luck with the new kernel I'm sure everything will be fine.

2>wipe cache partition
3>flash back2ext3

I think i will stick to this ROM for a while,untill temasek or someone comes out with a fully functional ICS/jellybean based ROM.Will never flash stock LG ICS's based ROM even if LG bring it out(Hope LG release it soon that shud provide d missing drivers that we urgently need).
Temasek your ROM is d "project butter" for me.I dont feel d need to wait for jellybean ROM.And yes i already have cwm 5.0.20 version recovery installed.
