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

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?

Sv: [Q] 4x user wanting to understand O3D's status, for dad
V21E is Gingerbread.

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:

P920 Custom Rom Issues

Good day all I have a Problem that I can not resolve or I am doing something wrong. I had a Sony Play before and flashing Rom on it was a breeze, but i have got myself a lg Optimus 3D and seem to be difficult. When I am on a rooted gingerbread Rom with cwm touch installed everything is working. My Sim card is working and I have no random shutdowns. I have installed a couple of Roms on my phone and all have the same problem. What I have installed is the Walkman Rom, Miui v5 3.6.7 and Miui v5 3.3.29. All have the same problem . When I did is a factory reset,clear cache and install Rom everything works. When I load up the newly installed Rom I have random reboots and my Sim is not detected. About 5 minutes into using Rom it freezes for about 5 seconds then the screen turns black and to get it back on I have to do a battery pull. I have tried with ICS Rom but get boot loop. Can someone help me with this issue that I am have problems with. Thanks for you time.

OK thanks for the ics tutorial very helpful. But don't mean to sound like a newbie but how can i solve the problem with my installed custom Roms not working?? Or will this work to with customs jellybean Roms . Thanks again for you helpfulness and time.
Chrisdzie

For ICS based ROMs to work you first need to install ICS.That explains the bootloop. Normally you can't jump from GB to an ICS ROM. The guide shows you how to do that. Then you can choose XBSA ROM or whatever working one you like.
I have not used CM based ROMs, as 3D has not been made to work in these (there is no official LG JB for this phone yet). So, I am not sure about the install process for those.

There's no shame of being a newbie everyone was once a newbie before they become masters.

Well before I have installed jellybam v 7.8.0 which is a jellybean based Rom. Loved the options and worked fine, but after a day or two my internal storage became full and phone freezed up and unresponsive. Did research and found out that it was a bug. I installed that through official GB Rom. So I went back,then tried to install miui v5 and then walkman but they have the same shutdown and sim not detected issues. People with those Roms installed don't seem to have those issues. So you can see where I am confused. Thanks

Ok,ok,ok I think I have found the problem but don't know how to fix it... When I install the custom ROM my imei number is blank which is causing me phone to crash. When I revert back to stock ROM my imei number is back and my phone running without any problems.. Is there a fix for this, or did I need to do something with this before installing my custom ROM.
