Rooting questions

Hi all, I'm a new P920 user, although I've been using a P500 for ~ 2 years.
So here's my questions: I'm using V20c (23/2/2012), 2.3.5, baseband L6260_MODEM_SIC_01.1042.00, kernel 2.6.35.7, NOT rooted.
I'm planning to update my rom to V21e with ROOT for everyday use.
I already have the .kdz for V21e (Italia version, downloaded from http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP920/AITAML/V21e_00/V21E_00.kdz)
I also have the megatron folder, the kdz folder with B2CAppSetup,...
So can V21E be rooted now, using megatron? Or is there any other method? If it can be rooted, then what are the steps that I should follow:
_ Root my v20c first then kdz the v21e so the root may remain?
_ Or, kdz to v21e first then try to root it?
Will kdz to V21E grants me the V21E baseband (to flash custom ROMs like prometheus), or I will have to upgrade that first?
Also, is there any drawback in v21e? Like less battery life and such? Is GhostCall completely fixed? Thanks in advance.

You can root 21e with megatron.
After updating to v21e you can root and install any rim that is based on v21e like promethius rom.
Buttery life is good for me and I don't have any ghost calls. Hope didn't forget anything

First flash to v21e then root with megatron
LE because I was in a hurry back then:
Well I don't know how really works the kdz thing, never used it, never interested cause mostly, for upgrading and recovery I use the LG Update tool. In this way I managed to recover and update my phone when I made a wrong flash of a v21e rom on an older baseband - no network what so ever. So, I used the LG Update tool - Customer Support - Emergency and recovery mode and with the IMEI and/or serial number I've been able ro recover my phone and, in same time, update it to the newer v21e version.
i don't know how's your phone - mine is operator free, no network lock and I'm in Italy - where normally the updates for "free unlocked phone" comes earlier - at least I have this impression.
Ghost calls...none after the v21e. Battery life - I see no difference cause I'm not a constant user of something and I don't keep count of what and for how long I use. And depends on how you manage your phone. You might want to give a look to my thread of useful applications and contribute with something if you want. Click here

Thanks to you guys berni987654321 and BigBadSheep. I flashed v21e and then rooted it. No problem so far, except for the strangely low Quadrant (2000 and 2100, but I don't play heavy games anyway). Now I have one more question: now that I have v21e rooted and (kind of) stable, should I keep it like this or flash a custom kernel (I see there are 2 popular ones: BlueKernel and Promethius, which one is better?). Is there any change worth upgrading? Or I should just keep using it till ICS or JB?

I'm using promethius kernel 1.5 and I'm very happy with it. But super stock kernel by samno is very good too

You're wellcomed. I have the kernel that comes with the rom- waterbear latest. And I'm thinking to keep it this way till ICS or beyond. For scores...I never care for those, it's important that you are satisfied.

Can I know why?

Also, some more questions:
_ Anyone tried the official CM7.2 for our P920? How is it: performance, battery, any serious bug, is 3D still normal,...?
_ What baseband is CM7.2 based on? I'm on v21e, so can I just simply flash it in CWM or is there any other steps I need to do first?
Thanks in advance.

With CMs no 3D

As far as I know and I've read there's no 3D with CMs ROM and derivates and further more no HDMI functional also. But I might be in error because I don't follow that ROM.

cm is in my opinion the fastest rom with the best performance but there is no 3d at all (you can only watch 3d videos made with the o3d) and hdmi is buggy. you can flash it on v21e without any problems

Thanks for the quick replies. So can I install 3D apps like the 3DVPlayer or 3D Photo,... to watch 3D clips and 3D photos that are already created (both by my phone and from other sources)? And I can still take normal 2D pictures and videos right? And since no baseband changing needed I just need to do a Nand backup first then flash CM7.2, if there's anything I don't like I can easily revert to this stable ROM I'm using right?

You can only watch 3D videos no photos. You don't need to change your baseband and with an backup you can easily return to the stable rom you're using now

Good News for SU760 Users

Good news for SU760.
I have successfully converted the P920 rom to work on my SU760.
Why I did this, since there is already an existing modified rom for SU760? I don't like the korean rom for su760, that's why i converted the rom for p920.
I have tested the XBSA ICS themed rom. It works perfectly, no bugs as of now. I know that this technique will also work with some other roms for p920.
I have to ask permissions first to all the devs for p920 roms if it's ok for them. I will also try to make an update zip for easy converting (hope it will work)
sorry for my bad english.

UPDATE:
I just converted and tested the Promethius Rom V1.5 20F for P920 guess what? IT WORKS.!
Now I'm on testing on other roms for P920.

Another rom works to my SU760.
After converting the Acura 3D Max Rom, it works on my phone just like normal.
On testing with another one.

yeah that great

How do you do it please give some details. When I install P920 roms I get Inernel Memory card mounts issues plus buttons messed up back button works as search. Both of these problems solved with Bluekernel.
But there is one big problem that is camera gets flipped upside down. Please if you have figured out a way to fix it tell us. I'll be really grateful.
Thanks

Great! Bless ya
Hey! Great news dude! So when r u sharing? we are waiting u know

Sorry for the late update of this thread. I have been so very busy on my work. I even forgot to upload the converted roms.
I will try my best to get extra time to upload the roms.
I found a little bug on Promethius Rom V1.5 20F. When I use the USSD Code in dialer, I get force close on com.android.phone and it will also restart the GSM Network. I have a problems looking for the error in logcat. Hope someone could help me diagnose the problem to make it perfect. Thou this is not a big issue for me. i will also test the ussd code on XBSA and on some other roms that I have converted.
About the Official ICS for SU760, I will try to test it on my phone. But first I have to secure an Official gingerbread firmware for SU760 for backup purposes. Hope I can convert SU760 ICS to be use for P920.

Official ICS has bootloader lock so no CWM and no backup.

what is your problem about SU760.? just try to search the whole forum about optimus 3d, im sure you will find answers to your problem. that's where I start, and I think almost all problems about software in optimus 3d has a fix.

And, Chickinican, if you are on Gingerbread (2.3.x) ROM, your best bet is Megatron block string attack. However, if you are on Ice Cream Sandwich (4.0.x) version, I would dig a bit more since this version is somewhat secure so different exploitation is necessary and required to give you root access.

Youcan flash any ROM to your phone, just flash the baseband fix for the old baseband to get calls working, its floating around somewhere in the forums a little search can probably find it for you.
Hope this helped!

ok i can do that but i do believe there are phones out in this world that run on V21e baseband and i think people did put custom roms and kernels that run with V21e baseband ....
i just don't want to go through the trouble of fixing the baseband and then re-flashing ..... i just don' t have that type of time
so if there is a custom rom/kernel out there for V21e baseband then please give me the link .
but if there isn't any then i will either leave it like this because i can still do everything including making calls and more with this baseband
or i will flash the old baseband fix

Lol your last sentece is all you have to do
Just simply find whichever ROM you want to flash to your phone, it doesn't matter which one because even if it is for the v21y baseband, Owains BB fix will make it compatible with the old baseband, the Kernel has nothing to do with baseband compatability.
If you have anymore questions just PM me and ill help you out

For V21e, the best ROM I have seen yet is Temasek's CM7.2 variant. No need for baseband fixes (it's based off the v21e), you might have to run GetRil to make sure the RIL matches the Baseband, but you'll be just fine. I'm using an older version of Temasek's ROM and loving it! (only reason why I haven't upgraded yet is because I'm lazy).
It's a final posting for the ROM (since my guess is he's waiting for the true ICS release to work on), but don't let that scare you. It's a COMPLETE GB2.3.7 ROM.

Some help, Any help will be Appreciated

i have been using my LG optimus 3D P920, for like 9 months now, i never updated it, until last night, you may call it bad luck or stupidity.
I found this Rom- cm-10-20121208-NIGHTLY-p920 , I flashed my phone with it, it was successfully done, the Rom is amazing i mean speed and all views is really great, but there was only one problems I can't call, and i check my network setting it gives me error .

If you had READ the CM10 you would have seen you need to Change Baseband to V21D and update to the latest Nightly

Can you please give me some steps on how to do that, because i am lost here!, so that mean my phone still have hope isn't it ?

Your phone was 2.2 (froyo) or 2.3.5 (gingerbread) ?
If it was froyo you must update it officially to gingerbread (to update the baseband) and then flash thiaiz ROM .
But if you want CM10 you must flash a certain baseband as "defcomg" said . which it is v21d . Flash it with "lg smartflash" it is the easiest way .

My phone was 2.2.2 you may call it (froyo) since i got my phone i never updated to any other version , i was with 2.2.2.
Can you please give me a link for official Gingerbread? the CM10 is very buggy i think i mean it drain my batter pretty fast and it doesn't have the 3D space anymore. Please send me the link for Gingerbread so i could flash mine, Thank you for helping me !

[Q] 4x user wanting to understand O3D's status, for dad

Hi guys, and fellow LG users, I'd like to find out what status is P920 on now cus my dad is using my old O3D. i wish to freshen up his phone alittle (and hopefully he'll love his phone more):fingers-crossed:
coming to Optimus 3D's forum feels like venturing into another manufacturer's phone. There's just SO MUCH THINGS going on here!!!!*stunned*
I know i should be doing search instead of starting a thread, i did but which unfortunately, doesn't paint me a good enough picture and story of P920's official FW status - I tried but getting bits and pieces of info out of an forum with so much more activities isn't easy
But i myself did abit of reading too, just that i have some questions in mind.
Is V21E Gingerbread?
I my guess V28B is the latest and is ICS, AND, is leaked (isn't official)
Are the V28Bs floating around Euro Open?
Where can i download the latest available ICS? besides baidu
Is there anyway i can flash O3D that is similar to 4X? http://forum.xda-developers.com/showthread.php?t=2069723
Working on 4X is pretty familar to me. Are there any special notes i should know before starting work on O3D?
The O3D device in question is now on V20C.
THANK YOU IN ADVANCE!!!!
Edit: i read that there are reported IMEI changed occurences. what is this about?

I'd suggest installing 30b, Its AT&T's official ICS update and it works like a charm with xbsalls XBSAVX3D custom rom

Xbsall's v28b rooted is great had no problems with it and had better 3g network in uk.
Also xbsalls v7 3d rom is great too all the 3d works and no problem
http://forum.xda-developers.com/showthread.php?t=1963847

As you said, V28B is a leaked ICS ROM. It has some bugs, but it works pretty well. It's an Open Europe ROM that has lots of languages available.

Thanks for the responses
My dad doesnt like 3rd party modifications including custom roms
(I have nothing against them but as my first post mention i just want him to be happy)

The best and simplest way, if you want to stick to stock, is simply by flashing the kdz file of those roms.
As you know, the kdz files include all that you need to get the phone fully working.
V28B is the Euro Open rom, V30B is the American At&T provider rom. Both include specific basebands, one for Europe's frquencies and the other for America.
I don't know which one will give you better reception, but you can always change basebands after installing roms.
I recommend you the V28B over the V30B. Both are stock Android 4.0.4, but V30B includes AT&T bloatware, while V28B is clean and bug free.

i just managed to flash my dad's O3D but only possible on Win XP using O4X's flash method

AW: [Q] 4x user wanting to understand O3D's status, for dad
There's a new v30a which is better then v28b - you can flash it via KDZ (as you posted for 4X), via LG Flashtool (.bin+.fls) or via zip (CWM):laugh:
