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
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?
'Off course we dont get radio, but how many of us actually use it
Oh, and BTW, i am not a developer... More of a dummy

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
Could we flash for example a g2x kernel ( not rom) designed for cm7 on an optimus 2x with cm7?
No. Kernels and roms are designed on/for specific hardware which in case of o2x and g2x are very similar but not exactly the same, so it can brick your phone. Cm7 for that two phones are different, so are kerneal too. That and there are forums for each phone separately, so logical is that it will not work .
But I am sure that you can find more detailed info with googling .
Can O3D roms built for the O3D be directly flashed to the thrill (like normal thrill roms) without the need of doing anything different or changing anything to the phone? If not, what must be done to use their roms if possible?
Would appreciate an answer, thank you
Yes,they can be flashed directly.
but the O3D roms does not support 4G,but some users say they get 4g speed on O3D roms..
Hi everyone!
I successfully updated my P925g to GB v20c, rooted and got rid of all rogers crap.
I installed PimpMyCPU app to throttle CPU down when phone is not used.
Now I'm ready for next challenge - install custom ROM.
I read that CM-nighties are the same for P920 and P925. So what about other ROMs?
I used to have Optimus 2x (European) and played with lots of ROMs and basebands because I couldn't get 3G data in rural Ontario. At the end I found the problem - European model doesn't have WCDMA850 capabilities. So I had to get rid of the phone.
I would just dive and start playing around. But I read some guys were softbriking their phones
From Optimus 2x I know there are different RILs for different parts of the world. What about Thrill (aka 925g)? Should I worry about it?
And what about baseband? Does it come separately from ROM (like in o2x) or it will be reflashed with every ROM?
Thanks in advance!
The CM7 rom's are different for the p920 and p925. More on that on a sec.
AFAIK there is no way to flash baseband separate from rom.
Of note: the p925 and p920 use identical hardware so the key difference is in radio and partitions. Ergo if you'd flashed v21a (which is for the p920) on your thrill, you'd use the p920 CM7 rom, but since you flashed the v20c thrill one you'll need the p925 CM7.
