Soo i just bought a LG Optimus 2x speed.
This is what i did:
- I Charged it fully
- I installed LG software, drivers etc
- I plugged the phone in the computer
- It said new software available, so i pressed update
- It said update failed, please remove battery and put it in again, turn it on and press try again
But everytime I do it fails! Now it's stuk in update mode!
Anybody please anybody got a fix for this?
Root it and install cm7 on it
Or try the ota update function (settings>about>updates (i think))

I think you misunderstood, it's stuk in sofware-update mode! I can't do anything
I had the same thing. I tried everything and nothing seemed to work. Then I found an application called Smart Flash, I don't know how this program works out what to do with it, but I kept pushing done buttons and suddenly there was some kind of reaction on my PC and after I removed the battery and replaced it again the phone was back in recovery mode. the next problem was that there was no more OS to run. But the pc was able to find the phone again so I downloaded some mod and the problem was fixed.
So you need to google for Smart Flash.
The file is called: LGOptimus2x_smartflash.zip

Hi all,
Please help me out.I brought my phone 1 week back and installed cyanogenmod 7 on it.But after using it I thought its not so good in terms of look.So I decided to revert it back.I downloaded andoird 2.2 firmware from LG website and used KDZ to install it.But when I was installing it phone restarted automatically and LG logo appears and a black screen came.I tried to install many time but still stuck on this.Please help me..I blocked my internet connection and I tried with different modes like emergency and diag and disabled LG modem in device manager.Nothing is working.Please help me and whether I can get it to LG service center and whether they can find it out that I flash my phone.So that I can repair it telling it is in warranty.Please help me guys.This is my first android phone.

Thanks

Hello, this exact same thing happened to me, don't worry, your phone isn't dead.
First you might wanna recover your phone so you can calm down a little by knowing that your phone is alright. To do that you have to look at the LG logo that appear when trying to turn on the phone, if it's white with white letters, you are on Gingerbread partition, if it's Red (kinda of pink) with white letters, then you have the ICS partition.
As soon as you see that, you have to download from this link: http://forum.xda-developers.com/showthread.php?t=1969797 a toolkit that will recover your phone so you can use it again. If you saw a white LG logo, then download the Gingerbread version of the toolkit, if you saw a red logo, then download the ICS version of the toolkit. To recover your phone just follow the instructions in that post and in the program.
After that, you can relax a little by know that your phone is ok. Know you might want to try using Smartflash to upgrade your phone to ICS.
I also had problems, when using Smartflash do update the files 1 by 1, mine stopped halfway through.
Still having wifi problems though

dear experts,
recently i've rooted my lg optimus black, installed clockworkmod and instaled a custom ROM, this one was too buggy, so i decided to install another one, while it was installing, the connection was lost, and my phone now only has half of the software installed and doesn't turn on.
it is not showing any signs of life, no bootlogo, no less-black background, and i can't get it in s/w mode.
used smartflash.
i hope someone can help getting a ROM on it.

Oh. I understand your situation. Go over to the nearest LG Service centre and inform about your phone not working. Explain to them that you were using LG's software update tool to update your phone. From there, they will fix your phone.

I have the same problem..I upgraded my phone to the official ICS by LG..then I rooted my device and install ROM Manager..
then use flash clockwork recovery..after I reboot into recovery..and now when i want to power on my device it flash Security Error...I cant open it...can someone help me??
Ics doesn't support cwm. U should install an older version of gb and then install one of the roms from the development section wich support cwm if u want it. To install an older version u can enter in sw mode by pushing and holding volume+ and connecting ob to the use while it's turned off. I u don't know something u can ask me, had the same problem and solved it

Whoops accidental thanks.
Put in battery before trying to go into SW update mode, it works for me and prevents the random colours. Then KDZ flash your phone back to life.
