[Q] CM and LG upgrade

Sorry if these are stupid questions, at least they're short and I'm hoping for a good answer anyway.
Can one expect CM to include the fixes (or something similar) from the new LG update that are supposed to prevent freezes/reboots in their stable or in any of the nightlies any time soon after the update is out?
I do understand that this kind of depends on what the fixes are like etc.
Is there an easy way to change to stock+update from CM?
Does anyone know if we can hope for gingerbread on 2x (not g2x) any time soon?
Does anyone know if people experiences the same problems after flashing the gingerbread leak?
Thanks

Depends what the cause of the problems is determined to be. CM uses almost nothing from a stock ROM, just a few proprietary files are needed, everything else is built from source.
If the fixes are in those files, then it might be something they'd want. Currently the files that are being used are from the G2X gingerbread leak.

I might be completely offbase here. But people that have had the reboots on stock also have them on Cm builds iirc. That means that it could be the baseband ( I always refer to that as the driverpack when explaining it to my friends ) that will receive an upgrade. If that is the case then everyone who's running a CM build can flash the new baseband as well.
But those are just my very unfounded thoughts on the subject

Thanks to both of you for your answers.
A little OT, but regarding the baseband thing:
When I think of baseband I basically think of for example how my 2x differs from the t-mobile g2x and how that makes my cell unable to use 3g on the t-mobile network. This, if I'm not completely mistaken, is definitely hw, if not everyone would just have flashed to a baseband which supported t-mobile 3g.
I don't think this is the case, what am I missing? What advantages might there be from flashing another baseband? What are the basebands?
Thanks

Baseband is the radio firmware, it's the radio hardware that makes it unusable on certain frequencies.

[Q] Questions about LG 2x

Hi, can someone explain to me about baseband and RIL, I already have some idea but I need confirmations on some.
I updated my asian phone with LGP990AT-00-V20c-EUR-XX-AUG-02-2011+0_CP.fls as per instruction of this custom ROM: http://forum.xda-developers.com/showthread.php?t=1254359. The name itself suggest european, does europe and asia share the same exact bands for their phones?
Can this mess with my reception? Is there an asian v20c .fls and matching RIL out there that I should have flashed instead?
Unrelated questions: I went with this ROM(lg o2x gb stock mod by topogigi) because it's based on the leak LG GB roms and has minimal bugs and from my understanding is that CM7 based ROMs are very buggy? Like the radio and a2dp doesn't work and when I look at the CM7 bugs thread(http://forum.xda-developers.com/showthread.php?t=1173229) I keep wondering why CM7 is so much more popular. Can someone give me an insight?
My LG 2x has about 100mb usable memory on fresh reboots, is this normal or is it limited to that ROM(lg o2x gb stock mod by topogigi)?
Thanks for any info. smile.gif

CM7 is popular because it's built from the ground up and contains many extra features. A2DP works fine FYI, but FM radio is currently a no-go.

[Q] 2X / G2X differnece ? most stable rom ?

Hey,
ive just buyed a p990 and put my old Gw620 away.
I was looking at the Android development for this device quite some time.
But it kinda confuses me.
Firstly whats the difference between 2X / G2X ? p990 ? p999 ?
Ive looked in many threads, mostly people didnt answer it directly, some wrote they have different File Systems. Is that all ?
Im also following Ricardo's Development on G+, ics looks promising, but lack of media encoding is bad. Is there really not a fully working stable CM9 Relase Out there for this Device ?
Whats the last Official Kernel which got released ? 2.3.5 ?
Right now i cant decide which rom i should use, since i need a really stable but also kinda recent one...
(maybe waiting until april is best, ive heard LGs gonna put out a official ICS release for this phone?)
Sorry for many stupid questions and my bad english...
greetings

1) The differences between the O2X and G2X are AFAIK only the file systems. Therefore the roms for the O2X won't work on the G2X and the other way around. The hardware on both the phones are the same.
2) RC's ICS rom is the best one available, and it's actually pretty stable. Only video recording doesn't work properly because of the media encoding. (Link in signature)
3) You shouldn't flash original kernels. Use custom ones instead . They're better and have a better performance and battery life. Also, Roms always come with a stock kernel which belongs to that rom. So if you want to flash a kernel flash custom ones. (link in signature for ETaNa Kernel, CM/MIUI Only!!!)
4) CyanogenMod is the best rom out there IMHO. So you might wanna try that. They are very stable and perform really well. (Link in signature)

..except for the radio. P999 works on T-Mobiles 850Mhz WDCMA band, while the P990 does not. (P990h and P990hN do though.)

[Q] ROM/ Kernel/ Baseband?

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.

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.

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! Need some help here

Hello everybody, well i finally get this phone and i have some questions, i have been too into developing before but there are some differences with this phone.
Okay, lets start:
This phone has 2.2(froyo) my carrier has just finished the actualization for 2.3. so I NEED THE OFFICIAL LG ROM, WHAT I MEAN WITH OFFICIAL IS THAT WHEN THERE ARE OFFICIAL UPDATES, IT WILL APPEAR IN THE PHONE
Can i flash roms with the stock phone recovery without been root user?
Wich are the best official baseband and kernel for the phone? Does it change the performance?
In case you can help me you have to know im from argentina ( latinamerica ) just in case there are differents roms, bb, and kernels for every part of the world.
Thanks and good luck to everybody

1) you cannot flash Custom ROMs if you are not rooted....
2)Phone Recovery is available only with root and with CWM
3)Different regions,service providers and devices have different responses for BBs. Generally, the most popular ones are V20q, V20C and V20S for the stock ROMs and the corresponding RILs
4)Performance will change with different Kernels, BBs....such as Voodoo, Battery performance, Scrolling etc
If you like the stock based ROM, then I would suggest you to reach out for Django Manouche 1.5beta4 ROM which is on XDA Server...check for the thread....and choose Stefan's , Flix's or Spica's Kernel.....each are valuable in their own ways.

you have to root your phone mate...thats the first step in liberating ur phone.
STOCK ROM usually has a lot of bloatware and Custom ROMs are slimmer by removing unnecessary apps....so you can go for a Custom ROM without worrying about bloatware.
I had suggested you a custom ROM and this does not have any issues with different BB or Kernel...only thing u have to keep in mind....use Kernel made for Stock ROMs.I am using a V20C Baseband with the DJ 1.5beta4 ROM which is based on V20S sources...check my signature and you will have more idea.I am using my own Kernel too.
for CM7/CM9, you can use any BB but the RIL has to be only from Froyo...means V10 series RIL.
Custom ROMs are mostly flashed using CWM. Updates- some of the ROMs are updated by ROM manager....but my opinion is to download and flash manually. Some of the ROMs do not use the OTA tool for updation(honestly....this is better)
IMPORTANTLY MY FRIEND, read through the opening posts from custom ROM and Stock Kernel threads....and use search....you will know more information.
Hope this helps.Thanks and take care
