Stock 2.3 to CM7

Hello everyone,

-i recently bought a Optimus O2x which came with Stock 2.2 Froyo and i updated it to Stock LG 2.3.4 GB.

My Baseband at present is 0725

Kenel-2.6.32.9

LGP990-V20e (India)

My phone is Rooted !

I want to flash cm7 Nightly 204 to my O2x

1) i went from froyo to Gb and now to CM7 ,my Baseband is 0725 ,frankly i do not understand Baseband and Ril thingy's , so what will i have to do after updting to CM7 in terms of Baseband and Ril(GetRil?),is baseband country specific ?

2) i have also come across discussions of "ext3 and ext4 partition" , do i need to bother about it ?

3) for App backup from stock Rom to CM7 i have backed up using titanium backup Free , now after updating to Cm7 how do i restore backup ? Do i need to install titanium backup from market and then restore or do u ppl use different methods for it.

4) Do you ppl follow this guide only for updating to Cm7

On Screen Phone

I was having problem with On Screen Phone after update O2X to V20m. I still have problem after update to V20o. In the ChangeLog says that corrects the issue.

Somebody knows how to solve this issue?
[LG Optimus 2x] CVonV:
i was in pretty much the same situation as you (stock 2.2 to stock 2.3.4 to cm7 temasek's build based on nightly 204) and i am a total noob with all this custom romming

1) yes you will have to use GetRIL to find a matching RIL for your baseband. I had issues with my 1035.21_20110725 baseband and non-matching RIL (can't remember what it was now). My issue was that from time to time Airplane mode would enable and I couldn't disable it unless I reboot.

2) apparently ext4 is created automatically with cm7? someone please correct me if i'm mistaken as I really don't have an idea about these filesystems/partitions to be honest (I would actually like to know how you can merge the 5.5GB internal SD partition with the 1.5GB internal phone storage)

3) yes that was the method i used. install titanium from market then point titanium to the backup folder on my external SD card then restore from there.

4) yup i just followed those instructions under "Method via Recovery"

---------- Post added at 06:09 PM ---------- Previous post was at 05:50 PM ----------

i have a couple of questions myself.. i am on temasek's cm7 build 23

1) is there a way to decrease the timer on the camera? the lowest is 10s and I need the 2s timer that was available on the stock camera. I've read there's a camera apk available for cm7 that increases the bitrate and/or fps for the full definition video recording. does this camera have a fast timer speed?

2) i would like to restore the stock music player as it has an awesome landscape mode. has someone backed up the app as an apk somewhere?

3) any way to increase the FM radio presets from 6?

4) any way to change the sound recorder quality?

5) actually, is there a repository for stock apps anywhere? i didn't think that far ahead when I backed up using Titanium.

cheers

this was the file name ...

and it was 203 MB ...
[LG Optimus 2x] izmax:
I think CM7 keeps write protecting my external SD card. Gallery keeps saying SD Card unmounted. Camera says the same thing. All the files are intact and healthy, i just cant write in it. It fixes when i reformat SD Card, but after a while, it recurs.

What is the fix for this?
[LG Optimus 2x] optimusG:
Hello...

I ve just bought a "Made in Korea" (is that good?) Optimus 2X and I am a bit confused. I have experience flashing android phones but I don't know which is the best way to flash a custom ROM on my Optimus. The phone has 2.2.2 (I made an OTA upgrade) with LGE version: P990-V10d.

So I need to flash a CM7 via cwm. Which is the best way? Could this work?

Thank you
[LG Optimus 2x] Rusty!:
Yes that will be fine.
[LG Optimus 2x] victoram:
I'm using mods and programs, but still, i dont really feel like using a DUAL CORE , TEGRA POWERED MODAFOCA PHONE.

a simple galaxy S ONE, is still UI faster, and smooth, and i just don't need to say the browser, that in the optimus 2x sux too much.

and it always get lags chaging programs, and ZERO multitask, because of its little shi**y ram

only thing perfect is gaming of course, but still sometimes get some lags... and you have to wait like 20s to stop lagging

YES IM MAD

Does this new kernels that uses SWAP, to create a virtual memory, make things FAST?

We have something STABLE to use on our phones?

geez, we have such a hardware, but with thrash software support, people with older single cored low gpu phones, experience some fast and smooth ui.

i have to sleep bye

Hi guys!

I'm currently on the market for a new phone and I'm unsure between this phone and SGS+. Can you share your thoughts on this? Sorry if this is the wrong place to ask this question :)

Thanks!
[LG Optimus 2x] lolozaur:
had both phones (currently using O2X). I'd say SGS+ is better on the battery side, but has poor performance with camera (lacks flash) and picture quality with low light. Max score in antutu with OC at 1.8ghz was 4700 (SGS+) while O2X scores a lot more. But you can't compare single core cpu with dual core performance. Also comparing the 8mp with flash (O2X) vs 5mp without flash (SGS+), you'd guess who is the obvious winner. But i would say the Tegra bonus from the O2X is a win.

I would recommend the O2X, but then again, everyone looks for something different in a phone, it's finally up to you.
[LG Optimus 2x] LarsPT:
First of all, thank you so much for your reply, I really appreciate it.

So I guess I should say what I'm mainly looking for in a phone :)

I will be extensively using social apps (e.g. facebook) and e-mail (gmail), using operator data connection. I will also use it a lot to share internet connection with my laptop (wi-fi hotspot).

Nice camera and GPS is also a plus. Battery life also nice.

So once again, taking this into account, what phone would you go for? Optimus 2X, SGS+ or another sub-350 eur?

Thanks!!
[LG Optimus 2x] lolozaur:
Well both phones have portable wi-fi hotspot so there's no pro and con at this point.

Social apps are present in both phones (facebook, gmail, twitter) but i found that facebook loads and runs smoother on the O2X. Also mostly all apps (including gmail) load faster on the O2X (but i would say that's because of the dual core cpu).

GPS software (google maps, IGO) connects as fast in both phones, so i wouldn't say there is a con or pro in this category.

Camera is better on the O2X and thanks to the flash you can use it in more situations, video quality seems the same in both (SGS+ can record up to 720p), but picture quality is better in O2X.

I would say battery life is nicer on the SGS+ because of the 1650mah (vs 1500mah in O2x).

And you would want to consider that the SGS+ will not get an official ICS Update (samsung confirmed it) while the O2x will get ICS (confirmed, but might be another year).

Last thing would be that, because the O2X is much popular than the SGS+, ROM development here at XDA is better than the one over at SGS+. You should check the I9001 Android Dev Thread if you are a flashing junkie (like me).

I always go for the phone that has the best ROM development here at XDA.
[LG Optimus 2x] kairi_zeroblade:
well first off i don't want to sound redundant but can someone here using a SU660 optimus 2x help me unbrick my unit and help me to get it flashed using the open2x project for SU660 a CM7 mod if my memory serves me right..currently i am in despair reviving my unit since i bricked it..

any reply will be appreciated.. :D

Need help about installing custom kernel on CM 7

Hi guys,

Currently i just rooted my phone and successfully install CM7 KANG by Koboltzz (sorry if i spell it wrong :D) ..many thanks bro for the KANGin... It really smooth and trouble free from my experience using it for 2 weeks now :D

Now I really want to take my O2X to the next level by try to install custom kernel on it .. and my choice is Vadonka's kernel http://xdaforums.com/showthread.php?t=1427646

However i always failed to install the recent Update 2012.01.17 .. any version i tried I always got bootloop on CM7 logo...always stuck there and wont go in to the system. The only Vadonka's kernel i managed to install successfully is LGE-KaNG_120109 its super smooth and stable but i got a bug that i cant play my PES 2012 on it -- PES always stuck on konami logo and then force close. :eek:

anybody have the same problem with me ?

Is there any way i cant play PES 2012 on that kernel (LGE-KaNG_120109).. or is there any settings that i need to change ?

And are there any way to know what causing bootloop on Vadonka's newest kernel ? -- maybe is there something i need to do to diagnostic this maybe ?

(yes i did all the clean / wipe stuff before and after installing) but still it bootloop on CM7 logo on newest kernel.

other than that Vadonka has created or KANG one of the best kernel i think for o2x -- at least that is what my friend said :D

but still thanks to Vadonka

Thanks in advance for any help guys :)

how do I put a mod?
[LG Optimus 2x] DCbball4life:
Hi sorry if this is the wrong place to ask this question but im not really sure where I should...I am a noob.

Anyway the g2x is my first smart phone unfortunately I can not get it to last over 8.5 hours when in stand by.

About my phone: Running 2.3.3, apps only Pandora, Battery Monitor widget, elixir, juicedefender, studyDroid. I am roaming on AT&T with full coverage(4 bars).

Cell standy by 49%, Phone Idle 37%, Wi-Fi 11%, Display 3%.

Asleep 88% of the time however it still feels warm/hot

Basics: Factory reset have tried 5 times, with htc battery calibration method, Bluetooth gps background data is all off.

Did the alternate battery fix. GSM and WCDMA auto.

Thanks for any and all help. Sorry for the long overly discriptive post.
[LG Optimus 2x] lolozaur:
Try this -> Settings -> About Phone -> Battery Use ->Click the graph on top.

If you are using a CM7 ROM you should be able to hold down power button for Power Menu and do a Screenshot. I attached you my screenshot to see how a normal battery use should look like (14h since charge and only 27% consumed).

If possible, attach your screenshot so we could read the data, if not compare the "Awake" bar. Does it have more blue than my screenshot ?

Awake time will consume the most battery, it means the phone can't go into sleep mode (less CPU usage - minimum CPU usage = maximum battery life). Also check Phone Signal bar, more green means good signal meaning maximized battery life.
[LG Optimus 2x] LarsPT:
Hey Andrei!

I ended up getting the phone this weekend, and I'm really happy with it so far! Even with stock 2.2 it's a smooth experience, and I installed GTAIII to "test" it and it runs the game smoothly and so far, bug free. No random reboots or anything, like I've read on this forum.

I'll give it a week or two with stock, to get a feel for performance and battery life, and then I'll start tweaking it. From what I've read around the forums, basically I have to root the phone, get CWM, and then I flash what rom I want, whatever kernel I want, check if the ril and bb match, and it's good to go, right?

Thanks a lot man, I'm so glad for this forum and you guys. If not, I would have gone for a lesser product (SGS+) for about the same money. I hate when I get less bang for my buck than I could ;)
[LG Optimus 2x] lolozaur:
Yes, basically you just have to root it, install the recovery (CWM) then flash the ROMs/kernels/mods via zips in the recovery. I would recommend doing a nandoid backup from the recovery before starting to flash custom ROMs. Nandroid backups will make an exact copy of your system at the moment of the backup (sounds like stock ROM, so you would have a backup stock ROM on your SD) so when, or if you flash a faulty ROM and it won't boot, you can just restore your backup. This is also good in case you have a warranty on the device and need to send it back (you usually send it back with stock ROM so you don't give them any reasons to deny your warranty).

I would say the fun of having an android smartphone is searching for custom ROMs that fit your needs, and kernels, and reading up on a lot of forum information about the hidden potential of your device and using it. Case if we wouldn't want to bother with custom ROMs/kernels, we would just get iphones or nokias :)

For now, the only downside of this device (i've experience) is HDMI mirroring to a TV is laggy (don't know yet if it's a phone issue, or the cheap HDMI cable and adapter i bought).
[LG Optimus 2x] DCbball4life:
I am running 2.3.3 ROM as I said before. If I root it will my battery last longer. This is a serious problem and I have no idea how to fix it. My chart doesn't look anything like yours and i didn't even use it the phone just sat locked in my pocket.
[LG Optimus 2x] lolozaur:
Looks like you have two problems that discharge your battery : you have bad signal strength (green is ok signal on 2g, yellow is ok signal on 3g, grey is bad signal) and even though your screen is not on (you are not using your phone) the phone is not sleeping and is awake (different bars comparing awake vs screen on). Also, i'm seeing WiFi usage without screen on, that's a bit strange. 3G is a big battery drainer, i only use it when wanting to browse something really quick, rest of the time i'm using 2G.

99% of the times you're thinking the phone has a problem cause it's dead in under 8h, the problem is from software you've installed on it that won't let the phone enter sleep mode to preserve battery energy, and keeps the phone awake, with moderate/big CPU usage so that's where all the battery energy goes.

I see you are using JuiceDefender (or some sort of battery saving software) - i personally don't like those kind of apps, i just use the Power Control widget in CM7 and turn off data/2g/3g/wifi/gps with one click after each time i'm done.

wajkiui

sorry new to forum, i hope im at the right place to ask. tried to post on developer forum but i cannot since new member

but does anyone have problems with wajkiui (2.1.20) and vadonkas kernel (latest Jan23 test), now having lots of sudden deaths, and wont restart in recovery with the 4-wayrestart tweak only from CWM.
[LG Optimus 2x] DCbball4life:
I have a text/call only prepaid plan and through out the day I have background data turned off. I tried the phone with nothing on it stock bare bones in airplane mode with the settings i have mentioned in all previous posts, result dead in the same amount of time roughly 8.5hrs or less. Here is today's usage. Any one have an idea?
[LG Optimus 2x] lolozaur:
what ROM are you using ? it doesn't look like stock, or is it ? i would suggest flashing temaseks latest Kang version (47) if you are ok with flashing custom ROMs. It might be a bug on your current ROM that's leading to a battery drain.

Also another hint for good battery life : use 2G networks as default (no auto in GSM Mode, only GSM) and use the Power Control (available in CM7), but add the Data and Network mode button. This way, when you want good internet speed, you first enable 3G network, and then data mode. When finished, disable them both and you're back on 2G network.

Leaving the network mode on auto, Cell Standy will take a lot of CPU usage (and battery power) always searching if your current signal level (2G) is good enough, or if you have some 3G coverage (even 1 signal bar) you will switch over to the 3g network with lower signal strength. This usually happens in a loop : 2G - 3g (lousy signal) - 2g - 3g (lousy signal) if you are not in a good 3G area.
[LG Optimus 2x] DCbball4life:
Sorry I forgot to add an Important image.

Ok so i did what you said but I'm still draining at about 1-2% every 5 minutes.

Also I believe I just have stock 2.3.3 Gingerbread. When I go to about it says 2.3.3 and I am not rooted therefore cannot have a different ROM.

Ok this may be a dumb thought but can these phones get viruses and would that be burning the battery..and can a virus survive through factory resets because I have done like 5 resets.
[LG Optimus 2x] lolozaur:
If you are running a stock 2.3.3 ROM and have this problem after a factory reset, i would recommend going for a custom ROM. Again, last image shows the phone keeps waking up and using the CPU (even though the screen is not on - you are not using the phone). That's not normal behavior, unless you have installed an application that does a scheduled task (like backup, scan, etc etc).

Again, i'm recommending you root it, install the custom recovery and go with custom ROMs (you might have a battery drain issue on your current ROM).
[LG Optimus 2x] SREEPRAJAY:
go to this thread and you have most of the answers....I suggest that you should root the phone and enter into the world of amazing developments and customizations done by our developers...including great stability and battery perf....I have more than 2days with some of the Custom ROMs i have flashed...

Life is nothing without a certain amount of risk mate...so move forward and enjoy the device
[LG Optimus 2x] Scougar:
Question: Is there a way to get the GPS and Wifi working at the same time? Seems like it only does it to try and save power.
[LG Optimus 2x] lolozaur:
i don't have any problems using WiFi and GPS at the same time, ex : using google maps with wifi and also GPS on for location. if you have problems turning them both on at the same time, maybe you're running some battery saving application that keeps turning one off.

also, although GPS may be turned on, you will not see the GPS icon in the notification bar until a application requires GPS hardware (ex : turn gps on and you don't start any apps, no icon; turn gps on and open google maps, you'll see the icon).
[LG Optimus 2x] LarsPT:
Or, maybe, returning the phone? Is it still under warranty?
[LG Optimus 2x] Scougar:
Bear in mind I am on the stock 2.3.4 ROM, and in the GPS threads it says they don't work at the same time. Looks like you have rooted phone, so maybe that's why?
[LG Optimus 2x] DCbball4life:
I know what you are saying its just I have never rooted anything before and am at the risk of bricking the device. I just don't understand why the phone is so awful on battery with the stock ROM. Could it be hardware related instead of software related.

As to the other response I recently bought the phone off ebay and am unfortunately requesting refunded. Love the device hate the battery.

Today i wanted to start experimenting with the optimus 2x .

I rooted the phone , installed clockworkmod etc ...

Everything went fine ! First off all, I made a backup in clockworkmod recovery .

When i start up the phone ( stock rom 2.3.4 ) , make usb connection , i can see in my external SD card there is a map "clockworkmod" with backup inside => backup OK !

The question is , if the backup contains everything ( the rom , the installed apps , contacts , user preferences , ... ) ? Or is it just the rom ...

Because i want to flash another rom on the phone , butt when the new rom doesn't like me , i want to use the backup and recover ! Hope the phone is in same state as it was before ...

i was trying to instal a rom with rommanager and now my lg not boot,only apear the lg logo for 2 second and then i have black screen,please help
[LG Optimus 2x] Scougar:
In the Anandtech review of the O2X they show a picture of the antenna/aerial connector.

Firstly: What antenna? Is this for GSM (phone signals), GPS or wifi ?

Secondly: What is the unused port next to it, as it look like an MMCX connection/connector but I'm not sure? Obviously I was thinking that this could be for an external antenna :-) (It looks almost identical to the Motorola V3/V3i external antenna port, and you can get an official cable for that :-) )

An before you all jump to conclusions about it not... if you look directly below the microSD slot, there is a small circular cover, that is directly above the port, ready to be used and abused :-D

Update: I still would like answers to the questions above please :-) BUT... just to help prove things, I ordered two antenna's: First with an MMCX connection, the second with a connection for the V3i RAZR as that appears to have the same connector as the TG01 and Optimus 2X :-) Getting better phone reception in the office with an antenna will be very beneficial as it is incredibly intermittant. I will let you know my findings :-)

Hi all,

I would ask the question in the appropriate Dev topic but since I'm a noob here I'm not allowed to do so yet so here it goes:

I've got Alien Revolution 1.4 Rom installed and everything is fast and smooth and nice, except for the feedback of the softbuttons, it's just too strong compared to stock.

Is there a way to reduce the strength?

Thank you!

Now , i wanted to test my restorepoint ( after installing CM7 ) . Going into clockworkMod recovery => restore => selected my backup .

The phone restores = Reboots => stuck in bootloop ?

Do i miss something ?

EDIT : Trying EXT3 converter now => noticed on this great forum , that CM7 uses EXT4 => when reverting back with original rom and restore point , i have to use ext3 converter ...
