Custom ROM for P990"H"

Hello...
Since there isn't a P990H specific forum or ROMs available, I thought I would my questions here:
1. Besides the baseband (i.e. RF) side, are the P990 and the P990H same? How about P999?
2. If #1 is true, I assume I can use the custom ROMs for either P990 or P999 for P990H. I looked the CM zip files, and there isn't a baseband update included, so I am inclined to think I am right. Does anyone know for sure?
3. What would you consider the most stable custom ROM at the moment? Modaco FR19, or CM7? I am after the ASOP experience as much as possible.
I just bought a P990H (to be used with AT&T SIM), when it arrives, I'll be diving into getting a custom ROM installed and wanted to make sure I don't end up with an expensive brick.
Your help is much appreciated.

As far as I know, most of the p990 Roms and kernels are not compatible with the P999. You should see the pages of the roms you would like and ask their coders. if they are compatible.

OK... so, if the P990 ROMs aren't compatible with the P999 ROMs, how about the P990H? I've seen people with P990H who flashed P990 ROMs, but I am not sure if these are limited to a specific set of ROMs or all.

have a P990Hn and customs roms are working for me... The best working rom i found is the Modaco Gr2

Thanks for the confirmation! Did you just follow the same instructions as the P990H for loading custom ROMs?
I would love to hear your assessment of the Gr2. Is there any glaring thing that doesn't work?

By the way, are you using the stock baseband, or did you update it? If you updated, which one would you recommend?

Everything is the same! No special instructions to follow
And everything is working on this rom and it's been pretty stable for an alpha the only issue i had it was because i didn't wipe before and after the rom installation.
There is also a Gr3 comming at the end of the month so it's only getting better

No change on the baseband, i use the stock one
From the research i made it look like the only difference between these phones are the frequency they can work on (yours is on 850/1900 i think) other than that i don't think the modem on those phones are different.

i was looking for some info as well. does flashing a custom rom change the baseband or 3G bands of the p990h?

No, if you dont update the baseband (and you shouldn't) then you'll be okay.. You should probably also save the RIL from original ROM (and put back to the new one) so that everything is working as it should. the RIL is located in /system/lib/lge-ril.so

Thanks For the info guys

New to Optimus x2, Some questions

Hello!
I have just bought my new LG Optimus 2x, and I have some quesitons.
With this phone i have shifted from symbian to android and i have some questions.
Firtsly, (not sure if this is legal to discuss here) do cracked apps exist? Is there something like jailbreaking on iOS?
Secondly, I have seen a lot of talk about rooting. What does rooting actually do?
Thirdly, I have checked the CM7 topic but it is just so big, and the last opdate on the first post is very outdated. Can you explain where to find the newest updates for 2.3 version of CM7 and how to mod my ROM?
And lastly, which launcher do you suggest to replace the stock LG one.
Thanks!

Rooting is jailbreak equivalent, getting "root" admin access.
Apps, well you just search for .apk files on the usual sites, filestube etc.
Cm7 I don't think is the best option at the moment, but I'll let someone else cover that.
Goodluck with your new phone.

Rooting gives you access to admin account so no need to jailbreak something lol, more simple.
Same for apps, Market is full if apps and most if the time you have free ones that will suit your needs.
At the moment you have to choose between CM7 and the leaked GB (like the one I run).
CM7 is still in RC stage but is usable clearly in daily use, leaked GB roms have still some bugs but very active dev are working in it and performance is great !
Not very hard and long to go from one to another BTW... Help yourself and hop in the train!

For speed and clean android-software I would recomend CM7 (android 2.3.7). If you would like LG Software built on android, like stock, there is some leaked customized Roms to install (android 2.3.4)
CM7(CyanogenMod7) : http://www.cyanogenmod.com/
You'll know how to navigate to download of CM7 for Optimus2x when you click on link
As for how to root and flash (install) it, you'll find the answere in the forum if you just search a little.
good luck with your new phone, and welcome to Android comunity

I am running cm7 after being on miui for months and I really cannot fault it so much faster!

I am guessing that means the same as SimDroid said "stock LG"
So, what advantage does stock LG firmware have? If its 2.3.4 it's older. Is it better optimised for optimus 2x?
I have checked the developer subforum for 2x but haven't been able to find any usefull information on the leaked roms.
Could you help me with that?
Cheers!

The gingerbread rom we're all using at the moment is the 2.3.4 gingerbread rom, but there are multiple variations and community edits of it.
I'm guessing your phone is on 2.2.2 at the moment, which is a pretty horrible release.
Anyway go here: http://forum.xda-developers.com/forumdisplay.php?f=1002 and pick one. I'm currently using Topogigi 1.9 which is the fastest ROM i've tried, no errors that I know of, fast boot time too.
You need to flash baseband and kernel also, see:
Baseband

And http://adf.ly/2SKAm for the rom to flash.

The advantage of stock = leak GB is that every feature of the phone is working. With Topogigi ROM you have many bugs that have been corrected, and a custom kernel with many tweaks in the system that makes this MOD extremley fast, and very good. The remodded 2.3.4 GB firmware are very different from the original leak.
On the contrary, as it is a leak version, there isn't any official source available, so it's often hard for dev to fix things. And it's not opensource.
CM7 is opensource at 100%, based on Google android sources plus all the dev work. Recently a big improvement was made as Aramcee (the dev leader of O2X CM7 branch) managed to make A2DP work, so now you can have Bluetooth headsets working in CM7, which was not possible before.
Still no Radio FM app in CM7 as radio stack sources are not available, and HDMI mirroring works only at 720p and not 1080. The differences between 2.3.4 and 2.3.7 are not major,in Android versioning the third number means minor improvements most of the time not noticable by user.
Both enable overclocking/undervolting if that's interest you. They are both very smooth and snappy. In CM7 there is a very good support for HID (keyboard, mouses and so on) via Bluetooth. Not in stock GB (no sources).
CM7 was a bit instable those past few days but it should be corrected. Every night you have a new build, but you don't need to reflash every day as there are not at each time new things for Optimus 2X. Upggrading is trivial as it doesn't wipe your data, takes a couple of minutes.
For custom stock ROM, updates are more irregular, but very frequent too.
So no real objective differences between those two families of ROM. If you need HDMI and FM Radio you have no choice.

Okay,
Thanks a lot for your answers and your time!
One last thing:
Lg launcher
Launcher pro
ADW.launcher
slidescreen
go launcher EX
Which one?

That's like asking "Red, Green, Blue, Orange, White. Which should I choose?"
Try them out and see which one you like the best. Personally I'm partial to Launcher Pro.

I like launcher pro but it's rather limited in free form

Personally I like ADW. Its more customizable than other launchers. You can also try ADW Launcher Ex. Its a paid version but worth it.

I would go for Go Launcher or Launcher pro. Both fast. ADW for me has been known to be laggy at my end.

[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] Porting G2X roms for our O2X?

Hey!
After looking through the G2X Forums, i see there is a hell of lot of roms out there. (Heck they even startet porting ICS!!) That's much more than the 3-4 we have. Is it possible to port a G2X rom to our O2X? Isn't it just a change of partitions?

sorry, i dont thing there's much chance of it happening.
& dont worry about ice cream sandwich, we will probably get it soon enough after google releases the source code

so what is real difference between both of them? i mean from the outside they look the same...i have a optimus 2x and i really would like to know

The phones are almost identical, though each of them have very different filesystems which is near impossible to change. plus i think it can run hspda 850mhz frequency i think. Other than that, they are exactly the same.

Different partition layout and different radio hardware.

It doesn't really have anymore ROMs then we do, just some minor changes, but they're based on 2-3 different roms like ours (Ok, they do have ICS port also). There just are more cooks, not that many devs. BUT, they do have a few more kernels and I don't see a reason why we couldn't use their CM-kernels on our phone if we wanted. But maybe we dont? Their stock probably won't work on LG stock, so.
Edit: I changed my mind, there isn't even more kernels. We don't need them.

But is there not a way to make ROM's able to work on each others devices?
Im thinking:
You flash a ROM for the G2X on our O2X.
Then you flash some G2X to O2X ROM Converter changing the partitions and HSPDA freq?
Badabim badabum.. lockscreen!
Possible or? If possible, then we have the 2x dev power

This can be done. Although I don't know to which extent. You will need to have hardware checks on which drivers to load, config, partition schemes, etc. It's a actually a very neat idea. Good for experimentation
More like linux running on different hardware configurations I'd love to see the day when we have a generic Android base that works on all devices. Then for specialized drivers, you can get them from the vendors -- bliss!

That would actually be nice - But would the shared Rom then not be huge? 1gb+?
Maybe some developers would look in to it and maybe share a beta for us to test out on different Roms and types of 2X'es. .

Yep. It could be significantly bigger than today's roms since you will bundle generic drivers for all supported devices. But that's easy to fix. The bigger hurdle is to make it work.

I have made a 2.3.4 rom for the G2X (based on an unreleased LG-L95G device) and planning on porting your new Italian rom to the G2X. If the flash is CWM compatible you don't have to worry about partitions as you only flash the system image and maybe a compatible kernel. The updater script just tells CWM to mount the system parition (the kernel knows which one) and you copy the files to the system. The kernel (at least for the G2X) is just a file called boot.img and you tell CWM to flash the boot image in a similar manner. I think it is just a matter of replacing the RIL files with the correct ones so the rom can talk to the radio, and swapping out drivers for other differences in the hardware. Other than the radio, as far as i can tell, the phones have virtually identical hardware. I think it would be a good project for someone and not that hard to port one of our G2X roms to your O2X devices.

Sounds good actually.
After you port the italian ROM to the G2X, tell us the difficulty and if you encountered any issues.
So, you are saying that a swap in radiodrivers and a modification to the updater script is all that is too it?

That plus other stuff. The thing that is concerning me is that in the installer script for the P990 rom there is a volume called "dbdata" being mounted. We don't have a mount called this on the P999, so I need to know what this is used for. Maybe we have something similar but has a different name. I need someone who is knowledgeable about the P990 roms to tell me what this volume is used for. But the thing that makes no sense is that the installer script is simply mounting it, doing nothing with it and then accounting it, so maybe it's a non-issue. The rom itself looks surprisingly similar to the one for the L95G with the exception of the UI customizations. I really think the only difference between the two devices is the radio chip because TMO wanted faster 3G (21Mbps vs 7.2Mbps). I don't know why memory is partitioned differently but that should not be an issue for putting the rom together, as the kernel takes care of all that. We have to hope that everything works using the kernel from the L95G. Due to partitioning differences using the P990 kernel is not an option.

There is nothing on the O2X that corresponds to "dbdata" and it certainly can't be mounted in recovery as there is no entry for it in recovery.fstab

What about reading the different threads in dev section? There is one about rooting.

Hi, i am also new to the LG-P990, i got 2.3.4 out the box and my LGE Version is V20d. Is that the latest? Used the LGMobile tool and that says something about Mobile phone not being supported??

If you want to check the newest version for your phone, use this link:

But replace YOUR_IMEI_HERE with (funnily enough) your phone's IMEI.

GPS troubles with Optimus 2x MIUI ROM
Newbie here and I feel like I am the only one that is having GPS problems here. I rooted my phone due to Wind mobile being extra slow with the updates for my phone and I cannot seem to get the GPS to work. Please help as it does not lock on. I checked the GPS config and see that it is set up for T-Mobile but I don't know which one I should use for my provider as the original Froyo did not have this option.
I also have troubles trying other ROMS as MIUI have seemed to lock me into theirs. Error when I try to load another ROM several times.

Yeah, CM7.0.1 is pretty old now, and I think you should try a CM 7.2 KANG. Those are very stable too. If you wish you can always add some custom kernels too to increase the performance.

There are so many 2.3.4 official LG 2x rom on the internet, all start with "V20..".
Generally speaking, the letter at the end means the location.
v20d is one of Asian LG official 2.3.4 rom distribute in Taiwan, Hong Kong and Singapore.
I only know that the latest version now in Hong Kong is v20e.
I am sure you will google a list of LG 2x official rom if you want to.
