[LG Optimus 2x] FaceTheSlayer:
LG optimus 2X was the cheepest dual core high-end phone I could find on a second hand market in my country. Of course I flashed CM7 :) (I'm on a Temasek's latest KANG) and my phone is rock stable and very fast. I'm using ADW EX launcher btw. I can only sugest to the OP to invest some time in exploring how to get ROOT and how to flash custom rom because that will be usefull regardless of which android phone you have. It is actually very hard to truly "brick" your phone, I've had a broken connection wih a PC in the middle of flashing a custom rom with ODIN on my old Samsung Spica because of bad drivers and I still managed to get my phone working easily :D
[LG Optimus 2x] Electroman365:
Man!! It keeps getting more and more complicated. I have no idea what "bricking" is, ADW launcher,... So many things that I don't know anything about.

Looks like the only other decent phone I can get on Windtab is the Samsung Nexus. It's $250 while the LG is free. I'm assuming the Nexus is better than the LG but It looks ugly with that stupid curve and it feels really cheap.So, I don't know. I'm still deciding, but is the Nexus worth the money?
[LG Optimus 2x] JohnnieDarko:
I was sorta in the same boat as you last week, (choosing between the Galaxy S, P990 and the Galaxy S2.).

1. The Galaxy S (with flashed rom and kernel) was already an awesome phone which could do anything you wanted, and during my short usage I found the P990 either equal (smoothness, gps fix speed) or even better (camera, wifi/3g connection strength, HDMI without $50 cable).

2. Flashing (= installing) new and better software is a piece of cake for this phone. Now I know you're new so it might not look as a piece of cake to you, but in physical steps it boils down to:

How to Root your phone. (= Give yourself full access to the phone)

1. Install software "LG United Mobile Driver 3.6" (use google) on pc.

2. Install software "SuperOneClick" (use google) on pc.

3. Connect phone to pc, then click "Root" in "SuperOneClick"

Done

How to Install custom firmware/rom/kernel

Assuming you have an external microSD card inserted.

1. Install CWM Recovery

Go to android market (on phone) and download ROM Manager. In ROM Manager choose "install/flash ClockWorkMod (CWM) Recovery

2. Download any new ROM you wish to install from this forum and put it anywhere on the phone.

3. Enter CWM Recovery mode

(When the phone is off: hold Volume Down and Power buttons. The white LG logo will come up, keep holding. Let go when the LG logo suddenly gets a blue background. Note: If you hold these buttons without succesfully installing CWM (step 1), then you will factory reset your phone and it will reboot again.

The following steps are covered in every thread on ROMs, every rom maker includes instructions on how to flash (=install) their ROMs. Yet in about 9.9 of 10 cases it boils down to:

4. In CWM Recovery, go to "Backup and Restore", and make a Nandroid backup. (You need an external microSD for this).

Move the cursor in CWM Recovery with the volume buttons and enter with the power key.

5. Do a factory reset. (Wipe Data, Wipe Cache)

Yes this will wipe your apps, appdata, messages and contacts so have that backed up if you want, but since you have a new phone, you won't have anything to save. It will not delete anything that wasn't in the Data folder, such as photo's/music.

6. Then go to "Install ZIP from SD card". Browse to the downloaded ROM (step 2), select it. It will install, will take about 1 minute.
​

That's it. Reboot.

You can choose from ROMs based on official LG android, or totally rebuilt from scratch such as CyanogenMod (CM7), or based on CM7. ROMs with a CM7 base will look significantly different from stock roms, and subjectively I'd say these are the better roms to look at as they've been more developed. You can find CM7 roms because they have the [CM7] tag in the thread title in the Optimus 2X Development forum.

Now read more guides on how to do it (because I may have forgotten something), I just wanted to give you a basic overview of what's waiting for you. Enjoy! :)

As per what you pay, its the best:)
[LG Optimus 2x] LarsPT:
Hey guys,

I think it's great that you're trying to help our friend Electroman here... but please keep one thing in mind, the ROMs in this section are for P990. Electroman, if you try to flash your P999 with a ROM for P990 you will risk bricking your phone. (Bricking your phone is basically turning your phone into a brick... or paper weight) ;) So please proceed with caution.
[LG Optimus 2x] Electroman365:
Thanks for the info and the instruction, JohnnieDarko. I appreciate it. I guess I have a lot of reading and learning to do if I'm going to keep the LG -and it seems like I am. I wanna know if it's possible to update to Android 2.3 . I read somewhere that people who are with Windmobile (canada) can't.

Thanks, LarsPT.
[LG Optimus 2x] LarsPT:
Electroman, if I were you, I would start here and get cyanogenmod working.

http://wiki.cyanogenmod.com/wiki/LG_G2x:_Full_Update_Guide

After that you'll have mastered the trickiest part, from there on it'll be downhill :)

Any help you need let us know!
[LG Optimus 2x] Electroman365:
Thanks again, LarsPT. I really appreciate the help. Would it be possible if I mess up downloading or updating things to reset the phone or do some kind of a restore and start all over?
[LG Optimus 2x] LarsPT:
First thing is rooting the device. I'm guessing SuperOneClick will work well in G2x as well. It's simpler than writing all those command lines like in the link I showed, but either way, that's how you start, by rooting it. If you screw up here there's not much you can do, but I don't think there's much to screw anyway.

At this point you should look for the app Titanium Backup in the market, give root permission to it and back up all your apps... or at least the important ones. Then you'll be able to restore them after you flash new ROMs.

Then you get CWM (ClockWorkMod) working. Like explained in the link I pasted above, it's simple. You download the app called ROM Manager and flash it. This step I don't think there's much to screw up. CWM is where all the magic happens. It's like the BIOS in your PC. It boots before your OS. To boot into it, instead of pressing F12 like in your computer, you press power + volume down, or you choose boot into CWM in ROM manager. Here you can do what you are talking about. You can perform a full backup of your phone and then if you flash a corrupt ROM or whatever you boot into CWM and restore your full backup.

Anyways, I'm getting way ahead of myself. If you're a beginner, start small. Root your device, get Titanium Backup and backup some apps. When you get that working let us know :)

EDIT:

You can start by following this link to root your phone, it should work the same with G2x:

djmcnz's method worked for me.
[LG Optimus 2x] Electroman365:
LarsPT, thanks again for taking the time to provide all the info. So that means I have to root my phone in order to be able to update to Android 2.3?

Another thing, does getting a good ROM make the battery last longer? My main concern is the battery life. Or maybe there's a better battery that I can buy.
[LG Optimus 2x] forforce:
I updated my rom to 2.3 after buying the phone without rooting it ;) so yes, u can upgrade to 2.3 without root. battery is the same like on any orher android phone , if u use it to the max it will last one day, but it can get u 2 days too. Depends on how much u use ur phone ;)

Even with custom rom I get the same battery life.
[LG Optimus 2x] LarsPT:
forforce is right, there is an official LG update to 2.3, and you don't need to root your device to update it. However, I would consider a custom ROM if I were you!

Check out my Quadrant benchmark without overclocking! Pretty cool huh?

Btw, I'd like to ask you a favor, can you do a quadrant benchmark and post it so I can compare my custom rom against your official rom? :)

Thanks!
[LG Optimus 2x] Electroman365:
Forforce, I tried to update mine several times but didn't work. Maybe because I'm with Windmobile in canada. Read somewhere that if we (Wind customers) want to update we have to root the phone or something. Can somebody please confirm this. I have the LGmobile Update program on my PC but every time I try to update it says "the cell phone is the latest version already, so you don't need to update".

My phone only lasts 14 hours on a full charge with no usage at all. I read about people claiming their phones last 2-4 days after doing some mods. Can I download "juice defender" first without doing anything to the phone?

BTW, any one knows if you can record calls on this phone or maybe if there's an app that allows you to do that?
[LG Optimus 2x] Dac0908:
If I'm not mistaken, your OTA update depends on your carrier, not LG. So you'll have to ask them what's up with that, maybe you can get it updated in service. If not, rooting is simplest thing you can do on your phone. And can be removed later so no worries. Just download SuperOneClick and follow instructions.

Look here: http://xdaforums.com/showthread.php?t=1179748

That is the software you need. First you root, then install ClockworkMod, then from CWM flash this. There are a lot of tutorials, but this would be a good place to start: http://xdaforums.com/showthread.php?t=1238804
[LG Optimus 2x] LarsPT:
You are right Electroman, official updates are, if I'm not mistaken, carrier dependent. At least they were for LG GT540, I think they are for O2X too.

I don't think it's normal to get 14 hours without any mods, but I can tell you for sure that using a custom rom, or even more important, a custom kernel will make your battery life better. If you are not "too" worried about warranty, I would strongly recommend you to use a custom ROM. Or at least try one for a week or two. You'll always be able to go back (if you do a proper backup up through CWM).

I've just flashed a custom ROM and kernel last week, so I'm still not able to do a proper "review" on battery life, but I can tell you for sure the smoothness and stability are amazing! It even made me go to cyanogenmod's site and donate a nice "beer" for them :)
[LG Optimus 2x] Dac0908:
I edited my post while you were writing yours, and now we say the same thing. Cool. :D
[LG Optimus 2x] LarsPT:
Hehe, great minds think alike :D

I'd still like it if someone could post a quadrant test result for a stock phone :)
[LG Optimus 2x] RainOfChaos:
same here...
[LG Optimus 2x] LarsPT:
From my point of view you have two choices...

Buy Samsung... great hardware, good software, good support, but you pay the price.

Buy LG... great hardware, crap software, crap support, 30% cheaper and then you flash cyanogenmod and you get great hardware and great software at a cheap price...

If you like flashing, buy LG, if you don't, buy something else, but it will cost you.
[LG Optimus 2x] iExitus:
Its your choise. If you have some time to learn things like installing a Custom Rom and so on the lg Optimus 2X is a very good Phone for a cheap price. The Hardware is very good and the ****ty Software can be changed so.
[LG Optimus 2x] pederzen:
I have an Ox2 for like 2 years now and all the things like"custom ROM", 'flashing", "root" and so on was chinese for me. I'm hungarian, my english isn't the best, still it took me max. a week to more or less learn the howto. Since that time i've become a "flash-junkie! :) There's few better things than trying out a new ROM, making your phone feel and look totally new, just like buying a new one! And it's always getting better! :)

I also had an SGS2 in the meantime, but i sold it, because of it's cheaply made housing and the fact that with some custom ROMs Ox2 is at least as quick and smooth, etc., if not better then SGS2. (Thx for our devs! :)
[LG Optimus 2x] LarsPT:
Electroman, you were wondering about the battery.

I am using temasek's kang #72 and vadonka's etana kernel from March 10th with DS and low overclocking, 48M Ram hack, and this is what I get with (what I like to call) moderate usage.

I noticed about 20 to 30% improvement over stock ROM. Even though battery improvement isn't extraordinary I can tell you the improvement on performance/smoothness is very noticeable.
[LG Optimus 2x] Electroman365:
Thanks again to LarsPT, Dac and the rest who chimed in. It's really appreciated. As of today, I'm officially an LG O2X owner. No going back. Like I said, I got this phone for free -as long I stay with Windmobile for 3 years- while the Samsung Galaxy would've cost me $250 and the S II was only available for the full price ( around $500-600) and of course nothing is cheaper than $0.00.

The Galaxy's stupid design and cheap plastic was not an option, so I had to settle on the LG. I like the looks of the LG and for me I'm just looking for a reliable phone.

Yes, the battery life is an issue for me but I'm hoping maybe with different ROM -if I learn how to do that- or a task killer (any thoughts on Juice defener) I might get more life, or worst case scenario buy me a couple of extra batteries.

Last time I was at a Windmobile store (about a week ago) I asked if I could update to 2.3 and the guy told me it was up to LG. Basically he was telling me it was LG's problems that I couldn't update. I think that was BS or he just didn't know crap. I also asked if it was normal to get only around 14 hours on a full charge and he said it was. I think he's one of those salesmen who don't know anything about what they're doing.

Anyway, now that the phone is staying I'm going to start looking into what I can do to make it better.

One last thing, any idea why the phone would go completely black while watching youtube? It's happened twice and I think both while in HD and I had to restart the phone to get out of the black screen.

Thanks again.
[LG Optimus 2x] Dac0908:
Salesmen/-women usually don't know much about technical stuff.

No, 14 hours isn't normal unless you're pushing it hard. You can drain it out in 5 hours of non stop watching videos - that is perfectly normal. But in real world scenario, I think that is hard to achieve :confused:

So, just update it. Try OTA, install that PC Suite, if it won't work do it the XDA way :) (but for that, switch to G2x forum)
[LG Optimus 2x] LarsPT:
Electroman, regarding the BSOD, I have a couple of remarks...

First, are you using a casing of some sort? Like some rubber case? If you are, you should be careful with this as I've read that this phone uses its casing as heat dissipator, and using a rubber case might lead to overheating. If you're affraid you're going to drop it, please consider cutting a hole in the back of the case so it allows for better heat dissipation.

Also, upgrading ROM will probably fix that. More efficient CPU usage will lead to less heat, thus less overheating problems, that shutdown your phone to prevent damage.

You should try and use all the features of your phone (GPS, data, wi-fi) to make sure you don't have a faulty device (hardware wise). When you're comfortable that everything works more or less as it should, then why not experimenting with flashing? That's what I did... Two weeks of test driving... and then, flashing :)

PS: NEVER trust a salesman.
[LG Optimus 2x] Electroman365:
LarsPT, no I'm not using any case. I'm not even using the phone. It just sits on a desk all day long. I've only used it twice to call so far. When I do use it I do so to play a game or go online and when I do that it's usually being charged. I've tried testing the battery life several times and not a single time did it go more than 14 hours WITH ABSOLUTELY NO USE of any kind and right after it shows 100% charge. I think it could be the many apps that are running. I have WI-FI, GPS off and brightness all the way down too. I'd like to know if Juice defender works.

I'm going to start experimenting with the phone (customizing it) now that I'm keeping it.

BTW, doesnt this phone have radio ? I cant find it.
[LG Optimus 2x] LarsPT:
Hi Electroman!

Okay so now I'm coming to a conclusion :)

Regarding the phone "dying" unexpectedly, this has been reported several times as an issue that "went away" with flashing custom ROMs. Me personally I never experienced anything like that, not on stock, not on custom, so I have nothing to complain about but maybe you suffer from that otherwise common problem.

Now, regarding battery life, please keep in mind that it is indeed very important in the first half a dozen or so of battery cycles to let the battery drain completely (even after the phone shuts off keep trying to turn it on until absolutely nothing happens when you long press the power button), and always charge it fully after that. If you keep charging/discharging at will without allowing the battery to perform full cycles it's normal not to have an optimal battery life!

If you stick to this recommendation you'll have the best battery life possible. I can tell you right now I'm at my second battery cycle with vadonka's kernel with DS and I have 55% left 1 day and 17 hours in. Pretty cool huh? ;) I'll post a screenshot when it's over!
[LG Optimus 2x] CarloIT:
I never had a smartphone before, i bought my dual on March 2011 and i'm very happy, i have 2 batteries, but many times i go back home without using the second .

Now i have the Nova HD ROM on ICS 4.0.3

but above all, think that you have paid very little for what others are paying much ;)
[LG Optimus 2x] Electroman365:
No no. My phone doesn't die unexpectedly. I don't know if you mean the black screen while watching Youtube though.

I've done the battery draining thing a few times but that hasn't changed a thing. But I've been reading that you're not supposed to do this with this kind of batteries. They say you should never let the battery drain below 20% or you might cause damage to the battery or the phone or something.

1 day and 17 hours and you still have 55% left !! Man, that's amazing. Mine is at 55% after 6 1/2 hours :( which really really sucks.

Hopefully I can get into all this stuff this weekend although I'm scared to change anything because it's something completely new to me and I don't wanna mess up my first smart phone or "brick" it.
[LG Optimus 2x] Electroman365:
I paid nothing :)
[LG Optimus 2x] CarloIT:
1 years ago i paid 460 when Galaxy cost 650 ;)
[LG Optimus 2x] rupppi:
i love the 2x. Everyone should buy this device... very good hardware and a daily use ics for a good price

PS sry for my bad english
[LG Optimus 2x] LarsPT:
I guess you read different things everywhere... Well, I did it like I said and that's how much time my battery lasts. It died last night so basically I get 2 and a half days with low usage. I didn't get to do a screenshot though :(

And I can say this is how I did it for my LG GT540, which I bought more or less two years ago, and now it's my girl's phone and it's still going strong with stock battery... so, I wouldn't know about the 20% battery stuff...

Regarding flashing stuff... everyone here had a first time ;)

If you start small like I said a few posts back I think you'll be alright.
[LG Optimus 2x] Electroman365:
LarsPT, 2 1/2 days is pretty damn good compared to the 1/2 a day I get on mine with no use. That's my main problem with this phone.

I read about the battery thing on different sites -I think including this one- and they advice against draining the battery, but I don't believe it and I too have been draining the battery until it's either dead or almost dead.

Yeah, I've just begun reading about rooting and stuff. As long as it's reversable I think I should be alright. Thanks.
[LG Optimus 2x] sumpf2:
maybe there is some app that is keeping the phone awake the entire time. When you shut off your screen your phone goes to sleep but apps running.in the back,can wake up the phone and drain the batterie allot.

Swyped from my GT-I9100 using xda
[LG Optimus 2x] csunny95:
For a phone cheap like this. 2x is already very good. With a good hardware. What you have to do is to flash a custom rom
[LG Optimus 2x] Electroman365:
Last night I downloaded my first app ever on my new LG. It was juice defender and man, what a difference ! :) It's been just under 6 hours since I took the phone off the charger and the battery bar still shows......full :D Normally by the sixth hour the battery is at or below half. I'm pretty excited already. I didn't really expect it to make sucha difference. I know it won't be as good with some moderate phone use but heck, even if it (juice defender) works in stand by it's still wayyyyyy better than before.

What app do you guys use to show battery info and % remaining...etc.? I've seen a couple but would like to see which one you recommend. Also, since I'm brand new to this (downloading apps....) do I have to worry about Viruses and malware just like on PCs? Is there something I need to know to avoid such things and is an anti-virus app recommended? Thanks.
[LG Optimus 2x] Gonox:
@Electroman365 you can use "battery monitor widget" - it's a good app that give you many info about battery. And for viruses you can use an Antivirus, sincerely I did't had problems with viruses that's why I don't use one
[LG Optimus 2x] Electroman365:
Thanks for the reply, Gonox.
[LG Optimus 2x] rupppi:
Avast mobile security is a pretty good antivirus and antimalware app and free.

[LG Optimus 2x] DupleX01:
Congratulations on your new smartphone. You will find a lot of tweaks/optimizations here for your device, however if you're planning to upgrade to a custom ROM make sure that you are using the proper ones for your device. Your phone from Wind is not an LG Optimus 2X, but a so called G2X(P999). So, avoid softbricking your phone using any Optimus 2X stuff.
[LG Optimus 2x] Electroman365:
Thanks, Duplex01. I realize that my phone is the 999 model.

Ruppi, I've always had problems with AVG on my PC. I don't know if it's better on a phone. But thanks for replying.
[LG Optimus 2x] LarsPT:
Hi Electroman!

I'm glad Juice Defender has worked so well for you! From this I deduce that it's probably some stupid carrier specific application that doesn't allow the phone to "sleep" properly, as I didn't have this problem with my stock ROM.

Regarding the virus issues, as long as you download apps from the play store you should be okay. I don't use any AV programs (exactly to save battery life) and I've never had any problems. There have been some apps in play store with virus but google is very quick to take those down as soon as someone reports them. Also, when you search something to download try to download from a known developer (you have the little blueish symbol) and look at the reviews.
[LG Optimus 2x] Electroman365:
Thanks, LarsPT. Yeah what a difference Juice Defender has made! In 2 hours it will be 24 hours since I charged the phone and the battery shows 75% (w/o any use). Before Juice Defender the battery would've been almost completely drained twice for the same period of time. Huge difference. Why isn't every body using this app for this phone ? I'm just wondering if Juice defender Ultimate would be even better?

So is the "play Store" an app that you download ? I've been checking out the "Market" app on the phone and there are a bunch of apps but it looks like some have ad-ware -according to some of the reviewers- and that's why I wasn't too sure about them and was wondering if there's a trusted site I can use to download some apps without worrying about viruses or adware...
[LG Optimus 2x] Dac0908:
When you enter Market press Menu > My apps and update them all. A week or two ago Market was updated and changed it's name to Google Play (Store), so I'm guessing there is a bunch of other apps that are waiting for updates.
