Here's a dumb question... I thought a kernel is incorporated with a certain rom. But when i read thru the dev thread, it sounds like there are different version of kernels and we can install different Kernels to different roms??? What exactly do the Kernels do? What would make the differences? Thanks in advance.
Kernels control the resources and filing system of the phone. Different kernels have different lag fixes, some over clock the processor. Some kernels re-orientate roms so i9000 roms work on the captivate.
He also makes some kick ass chicken. Sorry, couldn't help myself.

So, would you say the kernel makes a rom work on a specific phone ???

Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.
Hi,
This is a small CWM zip to add the [email protected] line to your existing boot and recovery partitions to fix the ram issue with the international unlocked bootloader. If the second mem is already there it does nothing.
The point of this is you can have a regular recovery flashed and fix the ram issue without wondering what tegra part you have, it preserves your serial number as well. More useful with stock boot images than custom ones that already have this done.
To use:
Flash with a CWM recovery supporting edify scripting. That means you have an unlocked recovery basically.The program inside the zip can be used on it's own to list the cmdlines already in your phone, or to set them to something else.
As cmdline, it lists, as setcmdline it sets the entire thing, as addcmdline it adds on to the end of the existing cmdline.Cheers!
Great! Looks like our bell friends are having good development as well.

So would i need to flash this once and then any ROM I install will have fixed RAM, or do I need to flash this after every installation?

You can just keep it handy on your sdcard and use when needed, it depends on the "rom" you flash, it may or may not have a ram fix solution built in.

It depends on the Kernel the Rom has within it, nothing else.
Furthermore, no offense. But this is kinda useless now. Did you not know we have unified Kernel's? If someone made a Rom without a unified kernel, they can basically shove that Rom.
I do not see a point in this at all. I guess maybe for testing old Roms.....

Hi,
I addressed this already in the OP. It's more for use with stock kernels.
Can you compile the motorola kernel source (pick one) and get a binary exact match for the stock Bell kernel?
No offense to the guys working on kernel's here, but I am not really compelled by the added features/bug fixes, and am concerned more about stability, especially when the source seems to be ATT based. Which is fine if you are running an ATT framework "rom/theme" I guess, even better if you have an ATT phone.
Cheers!

System Ram lists 816 total, so I should be in the clear or should I apply it anyways? Is there not a gig of ram on this thing or is some gpu/frame buffer dedicated?

So, if I understand this correctly, when I flash this it will auto-fix any ROM, kernel or custom recovery that I install?
hew dudes i am planning to buy this phone ie optimus 2x, and to sell my hd7 for the reason that its wp7. and nothing else. i found reviews and benchmark scores making 2x some what near to samsung s2. and that too in a low cost... i think this phone suite me.
so here are my doubts..
1) does this phone need to be s-off(changing/unlocking boot loader in order to flash recovery in htc phones) in order to flash a recovery? and if its so, is it easy on a non network locked( generic gsm) phone?
2) can i get any honeycomb rom for the phone, is it possible to load ics to it in future?
3) what about cm7 and miui support for 2x, ie is it in an active state like those of htc phones( i mean is it frequently updated)
4) what about the camera quality, is it good enough for hd videos and 8mp snaps?
5) what about audio quality from headsets?
6) how far can i oc the processor and gpu with out a crash?
7) is there any official gb updates out there?
pls ans me for my doubts, its my first lg phone, and i dont want to be disappionted. as i am selling my hd7 for this phone, i need a phone which is smarter than hd7. so you people should help me.

No, it's extremely easy to install CWM on the phone. No special skills required.

No, and yes. No, because honeycomb is a tablet-specific android-version. ICS will probably be released by LG at some point, but it is no certainty. What IS certain is that CM9 (ICS) will come for the P990.

That is device-specific. Most phones seem to reach 1.4 without any trouble, some can go as high as 1.65. It's a luck-of-the-draw thing. There aren't many kernels around which overclock the GPU, those that do set it at 350-365Mhz, default is at 300.

Yes. The first official updates started rolling out for Italy on November 1st, and are slowly and surely getting released for the rest of the world.
thanks for ur quick replay dude.........
and does flashing a custom rom/kernal voids my warranty, if i flash it back to stock before i go to service center? i mean is ther any way through they(LG SERVICE) can find that i had flashed the phone before?

It will, depending on local consumer laws, void the warranty. (Italian courts say it does not, for instance.)
Nobody can know for sure whether LG can find out or not, but the assumption is that they can't.
I base that on the simple fact that nobody, ever, has posted a post saying that "Hey, I restored a stock ROM, and LG still found out I had rooted before."
Nobody has said anything of the sort, so I'd say it is 99% certain they won't find out. But you never know. (The Samsung Galaxy S2, for instance, has a counter for how many times you've installed custom ROMs on it ;-))
I don't want to be too paranoid (i'm not as I run custom ROM) but you could imagine a situation where restoring stock ROM is impossible lol...

Found a great ROM totally based on a new concept of DUAL ROM. Both GR5 by Paul & MIUI12.2 bundled together by "ChinaGB". I have flashed this ROM today and its working well since last few hours. If interested you may try the ROM at link below. Screenshots also available there at Modaco.
http://android.modaco.com/topic/349332-gr5miui1202-double-system/
All credit goes to ChinaGB for bundling the ROMs. Thanks to him. I have only posted the link as the concept is great to me.
11.12.2011: Subsequently another DUAL ROM developed by ChinaGB again with GR5+CM-204. Link attached. Downloading. Will flash in free time.
original link : http://115.com/file/bhk2amyj/
link provided by s.don : http://db.tt/ATEV950e/
great going.
Thanks to ChinaGB for the ROMs & S.don for providing the link.
Edit: Actually both the ROMs are bundled by ChinaGb. S.Don only provided the link like me.

Thanks Partha...
No special tutorial needed. FULL WIPE needed, i.e., wipe data, cache, dalvik. Run CONVERT TO EXT3 by Paul and lastly flash. ROM will boot into GR5. Dont skip initial android screen. RONs can be changed by tapping dedicated icons. Lastly till now I have not found anuthing not working. Using MIUI at present. Only thing is battery seems to be draining faster than Topo's ROM & SPICA kernel. But nothing wrong in trying its an unique experience. Apps installed in one ROM shows up in other.

Partha, Thanks for the information. But, what about the free RAM? HD Video, BT, Wifi, 3G mobile data, etc?
How long is the battery after a charge?
BTW, I just downloaded tht...waiting for your answer....
Thanks once again
how will you install the available tweaks in each type of the rom? it will surely get into bootloop, afaik..
BT wifi working. 3g i cannot check. RAM is more than 100mb and UI is fluid. I have mostly used the MIUI part but I think v20l will also be stable. Battery is one point which I am still testing.
Regarding tweaks as pointed out by Helldroid nothing can be done. Both the ROM uses different kernels. MIUI uses swiftextreme and v20l uses probably default with tweaks like support for voodoo. RIL is also different for both ROMs and only customisation i have done is flashed RIL in MIUI part.
Thanks

I haven't calibrated my battery. You try and advise us if successful. I think try the MIUI side first because MIUI seems to be draining faster than v20l. BTW you can download ONLY 1.2MB updater in the Modaco site and flash it (I flashed it after wiping Cache/dalvik cache) to update your MIUI version to latest 12.9. Very Simple. I Liked the way of updating. BTW while flashng the update I first booted to MIUI ROM and then booted to CWM from MIUI ROM so that after flashing it boots to MIUI. Don't know if flashing from the v20L side would do any harm but I thought it safer to go by MIUI side since its a MIUI update.
I have applied the fr version changes to the rom for miui part so i think i wont be able to update the ota method . but i will try...
anyway there's currently a fr version being cooked with a customized miui
regards
does anyone know how to change gr5 to cm7 in this rom and if it is possible?

Yes, EXT3 ROMs are the most popular dual boot option. (Even though the dev community is inactive right now.) There are also other partitions such as EXT2 and FAT32 but they aren't as stable or fast.
I would suggest Midnight's bundle but I improved some things with my own Code Butter ROM. You can also try jerrytan93's FroYo series. It's everywhere and they have individual threads so i would be hard listing them all.
