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.

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

revert to stock

How do i revert my phone back to stock? I purchased it and it has cyanogenmod on it which is fine but I've not had a chance to experience what the stock look and feel is and I'd like to try this first before sticking with the custom rom.
I'm confused as to how to proceed. Is there a fully stock CWM rom somewhere or do I need to flash something using a different tool?

You can download the stock rom and read the instructions on how to install it here > http://forum.xda-developers.com/showthread.php?t=1035041

?? Will I be able to upgrade to an official ROM? And How to rollback a custom ROM ??

Hi all,
I have just installed a Overcome ROM 2.2 and now I have two questions:
- When Samsung get to release Ice Cream Sandwich, will I be able to update my GT-P7310 to Samsung's OEM ICS? If so, how could it be done?
- Second question is: Is there a way to roll back this installation to Samsung Stock ROM? If so, please let me know how to find the stock US ROM for GT-P7310. I have not found a working link, but would greatly appreciate the help. I prefer to keep the tab instead of taking it to the store for an exchange (I'm still on time to return it).
Thanks!

1. when samsung finally releases ics there will definately be a zip file here in the forum. just download it. do a full system wipe in recovery and flash it like a custom rom. should work fine.
2. the best thing to do would have been to make a complete nandroid backup from recovery of you stock system. then you could just restore the complete stock system. seeing as you have installed overcome already its too late for that. if you can find your stock rom you can however just flash it again. then check the guide for unrooting and you are back to as stock as it came:

Thanks pseudoheld. The reason I'm concerned that I might not be able to have the OEM ICS ROM when it gets released is the fact that I can't even find the zip for the stock ROM anywhere around here.

Flashing future official ROMs after unlock -

Hey guys! My apologies if this is a redundant question, but I just wanted to be sure:
If ASUS decides to actually put out an official KitKat update for this thing eventually, would I still be able to try it out / install it normally *after* I've unlocked?
If so, what exactly would be my procedure? Will I be blocked from getting or installing the OTA, or would the process be no different?
There's been some great progress it seems on custom ROMs for this thing. I'm a bit gun shy admittedly, as running custom ROMs on previous devices led to a lot of instability. I guess I want to ensure I'll still have the option to try out a future official build if I choose. Thanks in advance!

Yes you will definitely be able to update to KitKat once released. However you won't be able to get the OTA update automatically sent to ur tab once u unlock it. But its pretty simple to get it. After Asus has pushed the ota to devices, the also upload the firmware to their website. U would simple download that and place it in the root of ur internal SD, and reboot. Tab will recognize the update, and give u notification for installing it. And u continue with that. Very simple.
And as for the Roms , the cromix ROM is by far very stable ROM. I have tried it for very long time, and has no issues at all, and the plus side is u can do a lot of customizations yet the ROM still runs faster than stock. I strongly recommend cromix ROM.

Thank you! Answered my question perfectly. I think I'll pull the trigger on unlocking here soon. Cheers!

Your welcome and have fun, which I'm sure you will

This is not 100% true. The current official ROM will only flash with the stock recovery installed and not a custom one, so I would assume the same for any update.
It's not an issue to flash the stock recovery back but it will be an extra step.
Also if and when an official KitKat comes out you will more than likely have to wait until a new recovery is made that is compatible for a custom ROM after that.

I never understand why people are pining for the stock rom - no matter which version or update....
I would feel helpless and lost with only the stock recovery! Lately I've been trying to help several people on stock firmware with corrupted data, no custom recovery, no root, locked bootloader.... You're toast!
All you can do is send it in to Asus and pay a bundle! Whereas unlocked you just fire up fastboot or custom recovery and start to fix it!
Besides - once Asus releases a KK version for this tablet you can bet your.... house that sbdags will have a custom version of it out in no time. And it's going to be better than Asus firmware, receive frequent updates, can be flashed with a custom recovery....
A no-brainer IMHO

New G2 / 24A / What next?

I'm not new to rooting and flashing, except with the G2, VS980. That said, I rooted using an app called "AutoRec" from the Play Store. I then flashed TWRP 2.7. However, when attempting to flash the stable version of Cyanogenmod (10.2), I run into an "LG Security Error" and the phone won't boot past the LG boot screen.
Do I need to revert back to an older firmware to flash ROM's? Is there an LG VS980 flashing tutorial anywhere? I used the TOT method to get the G2 back to stock, and I'm currently back on 24A, but reverting won't be a problem as the stock firmware is garbage.
I know, this is a lot for one post, but I need the information. There are plenty of ROM's to choose from, but I don't even know where to start. I know it's difficult picking one, so which one are you using now and would you recommend it?

CM 10/11 nightlies are based on JB or 12B baseband while your phone has 24A or KK. You need to flash JackpotClavin CM11 5/21/14 release

And also, just for future reference (no disrespect), this belongs in Q&A, not development. Hope you get it figured out!

I appreciate your response. However, JackpotClavin seems to have abandoned development.

It's not a problem. I've been a member here for awhile, but never really post. I still should've known better.
That said, does anyone have any other suggestions for Google source-based ROM's?
I've recently gone with C-Rom. I noticed the size was quite small, and once it booted, I couldn't be happier. It's plain-Jane Android, and I love it!

Carbon is quite nice too, bigshotrob22 has been posting betas based on 24A to the thread, the last one is in my signature. Don't use the nightlies linked in the original post.
