Hi
I'm helping out a friend, which O2X I have rooted and flashed WIUI on to (I previously owned one myself too)
For some reason the phone started to get hot after a while and used up the battery fast, until one day where he couldn't even turn it on again.
Now, he has been trying to fix it himself with NVflash, but no luck, so now its up to me and you guys.
I have used the smartflash tool and flashed the EURO OPEN stock ROM and everything went succesfull, but when the phone reboots, the LG logo appears, and it bootloops.
I tried both with battery and no battery in, but still no cigar.
Any suggestions what I should try next?
PS: If I try to turn on the phone normally, nothing happens. not even a blink from the screen, but I can get into S/W mode and APX
Try lg update tool, choose recover as option, then choose imei as entrance

EDIT: The software says the update is not compatible (dunno if translation is correct, but you get the point)
Update is aborted :/
No more suggestions on what to do?
Tried:
NVflash
Smartflash (Flashed EURO OPEN rom)
LG Update tool (recover function)
The phone still won't boot.
Smartflash is the only solution like you said that the phone can boot in s/w mode try to dig some answer in smartflash thread or search in google i know you can find some answer there

Assuming you have carried out the procedures correctly, looks like this device is actually defective. Probably not what you want to hear, I know, but...
Before giving up completely, you can NVFlash it again (using the original 10C NVFlash from Modaco) and post the log here. Wouldn't get my hopes up though.

Dear all,
Last night I tried updating to V20N (Dutch) using the standard LG Mobile update tool, so via USB. After the downloading step, the update tool proceeded to install until 15% has reached. The tool says "communication error between PC and phone" or something like that. It tells to disconnect USB and remove battery and try again. I did this 4 times, but the phone itself stays in "S/W update" mode.
Before perfoming a hard reset (and losing all of my data) using one the unbrick tools, I solved this by using the option "recovery and emergency" in the options tab of the LG update tool. After 20 min recovery my phone was back and guess what? It had been updated to V20N 2.3.4
Now it feels more snappy, no more lag while sliding the screens. Apps running smooth. No idea about the battery life.
Same issue here can u please explain it further or a step by step guide.

In the menu of LGMobile Support Tool choose "Customer Support"
then click on "Recovery Phone"
in the pop-up window enter either IMEI/ESN/MEID or Model+S/N and click "Check"
Then the Mobile Update Tool should pop-up and start downloading+updating
Lots of succes!
Had the same issue a while back, even the emergency/recovery flash from LG tool did not work. Eventually the smartflash method worked for me, going back to v10a and the offical update with official LG tool to v20n worked after that...very strange...

Exactly the same thing happened to me just last night. I was prompted for a V20E (PHL) update. After download and install my phone got disconnected and was stuck on the S/W update screen even after I removed the battery several times.
I found a recovery step by step here and gave it a try. I unplugged the USB, removed the battery, reconnected the USB, pressed vol(-) (not sure about this it was already midnite and I was desperate) and pressed the power button. LG app connected and I chose recover. Entered IMEI and it started downloading again. I tried to get some sleep and a few minutes later I heard the phone startup sound. Hooray! Initially I thought I was back to V10D but the version confirmed I was now on V20E. Double hooray! Still a fail for LG though. Will the same adventure happen when ICS comes out (in two years or so)?
The problem is, that you probably had a cust ROM with ext4 support and that doeant work with stock ROMs, --> bootloop

No custom or root. I was running a plain-Jane V10D before the upgrade.
You should report this bug to LG.
I emailed customer service. They apologized and asked me to bring it to the nearest service center
same thing happened to me.. but what i did was i went to LG mobile in MOA and let them restored my phone but mine is V20b.. is V20e a newer version?
V20B was announced last month. I tried upgrading to that but it went into the phone disconnected error so I decided to wait until I can visit the LG kiosk.
Then V20E came out so I thought let's give it a try hence my adventure. V20E is still 2.3.4 though.
I can't post links yet so try to search for the firmware list. It basically says V10A >> V10D >> V20B >> V20E.
ah i see... thanks man.. i'm still new to these stuff i need to read the threads here to learn how to flash and maybe try V20e
My LG Optimus 2X from windmobile is stuck in boot screen. I recently rooted my phone which worked perfectly fine than I installed CWM ext which messed things up, phone was hard resetting every time it started up. So I went to the market place and installed CWM and installed recovery from within the app and decided to install [ROM] MIUI v4 2.7.20 [Multilang][New base] [25/07/2012] through the CWM app. It loads up in recovery FINALLY and I installed it. After reboot its just stuck on LG boot screen I cant go into recovery mode either it just reboots and gets stuck at boot screen. is there anything that i can do to recover the phone?

hey so NVFlash did work but now i am getting no signal, I went to settings> About phones > baseband: unknown. So I decided to use smart flash and flash the "LG_P990_1035_21_2011-06-22", it just wouldn't flash it loads up to 50% than i get timed out error. Is there anyway to fix this issue.
Thanks.

this might be an issue with BB and RIL combination...try to install the GetRIL app from the play store and try to install a recommended RIL....reboot and check...
you can try the smartflash after trying this...
Hope this helps
The problem was that I was flashing p990 firmware on my P999. oddly enough it ran but without any baseband. long story short I used the ROM from this thread http://forum.xda-developers.com/showthread.php?p=17258229 and it worked I was in the wrong phone section the whole time. thanks every one for the help couldn't have recovered it without your help thanks :victory:
ok, so i was using tonyp-harsh v28e vlite ics version before deciding flashing stefan v28g via nvflash
i started nvflash as usual (removing battery + vol up and down), APX driver was recognized and the installation process went smoothly.
the problem is, after i flashed the rom, i found it a lil' bit laggy so i think it'd be better to try CM 10 to find out which one suit me better.
so i turn off my phone again, removing the battery, and pressing vol up & down simultaneously. but then, the phone doesn't respond (yes, it give a blink, but the LG logo doesn't appear and APX doesn't show up in my pc). so, now i'm stuck on v28g
i've tried searching with some queries :

https://www.google.co.id/search?q=l...&sugexp=chrome,mod=2&sourceid=chrome&ie=UTF-8
and such
but it didn't give me an answer
i've also tried another version of nvflash such as this one by ProgMaq and another one by rmein, but nothing works
any suggestion?

I had the same problem as you face here.
I tried everything NV-flash, smartflash, you name it, no luck. Then I did a emergency repair in the LG updater.
Start the Updater, select "emergency repair", make sure drivers are installed.
Battery out, press Volume Down and connect.
Enter IMEI and S/N and repair program starts.
I had to do it twice, before it finished. I maybe had a bad USB connection or cable, but after "S/W update" showed up in screen on second attempt, I reinserted battery and it went very smooth.
Let it boot.
And then root with NV-flash and you are back in business with normal GB partition table.
I can recommend Tonyp's CWM 6.0.1.5 touch for NV-flash, when you have finished rooting.
It took me 45 minutes, with a not too good internet connection.
PS.: I did not try this one: http://forum.xda-developers.com/showthread.php?t=1715272
but since I could not call up NV-flash, I did not want to spend even more time trying.
Is it possible to make a downgrade to my rom só i can restart to use new cm nightlies

I dont think you can just downgrade with smartflash tools. V30 has a locked ICS bootloader if im correct and apparently my O2X bootlooped when i did that. Now i stuck and even NVFLASH fails
i downgraded my v28g to v20s with smartflash
Thats the answer....
Use Nvflash i downgraded many times from v28a,g,v30a down to v20 or cyanogen mod Its the savest way.
Im form germany... only found the german forum but the zips of nvflash work very well use it:

I think it might be time for me to throw away my P990 because im not sure if the VOL UP button actually works or is it the PC problem.

Anyway although I doubt smartflash could work for my case, I decided to give it try and flash V20B rom (starhub) via the .fls and .bin files method. It gave me an error when it was about to partition the "7 partitions". So i exited and unplug my phone as the SW upgrade screen on my phone turned to a blank screen. I wanted to try again and plug back holding the VOL DOWN button to enter SW mode. I heard the Windows sound notification (when a device is plugged or unplugged) as i do so but the screen was still blank. So i checked the device manager screen and saw that i entered the NVFLASH recovery mode.
Im confused as to how it would work now but anyway i was grateful to your post and that made me give smartflash a try still. :laugh::good:
the easiest way in your situation is using this [TOOL] Full Brick Repair (Clean & Easy)
It's nvflashable and already includes a CM10 nightly. Boot it up and upgrade CM10 with the built in upgrader. That's what I did yesterday. Then boot into recovery and flash gapps.

I had the same problem, and I leave the battery in the phone and it worked, try it
well
after reading some information, i solved my question using this thread
http://forum.xda-developers.com/showthread.php?t=1715272
thank you all guys that tried to help me.
i messed up my lg with installing ICS,now when i turn on the mob everything is blocked,picture of android is v10 and version inside is v30,i can charge it and i can get in s/w update mode. i tried smartflash but it goes to download complete but mob. wont reboot just turns on lg logo,i tried kdz updater but when i press upgrade start and normally its supposed to ask me which country to choose so i can put different country in my case it goes automaticlly to update. i have teamviewer 8 if maybe someone has time to help me so i dont have to take it to service(no money). thanks
now in lgmobile tool i did phone recovery and after i turn lg on on version it sais v10a and it sais i can start update to gingerbread and when i start on update on 15% it stops,any help?
after error i put manually in s/w update mode and it went all the way,it sais gingerbread installed but cell want reboot and when i turn it on there is no change.
on 90% of update on cell comes lg sign and stayes like that
hey man sorry for the late, I'm a little busy
just a question, when you flash a patched firmware, can you access to the recovery ? if yes, that's all, from there just do a wipe of datas (flash superuser if root is needed) and reboot. done.
no problem its never late, unfortunately not,thats was i am trying to do,i know i need to come to recovery but so far i didnt manage
which firmware did you try ? (give a link if possible)
unfortunately i am at work but i dowloaded v10a from, http://lg-phone-firmware.com/index.php?id_mod=1
these from that site are not patched, but stock...
download this (run to extract binaries) and follow my pdf guide if you have already the upk package
edit : or follow this online guide
ok i will try with this,can you just tell me will i try with kdz updater or with smartflash?
smartflash of course.
kdzu is obsolete since LG has restricted this method (there is a way though, but more complicated)
i have upk ofcourse,i tried so many combinations,maybe i tried even v20s patched but i will give it a go tonight after 10 p.m. when i get home and i will post results,thanks for now Ilko
Ilko this stock v30 recovery,would that maybe help in my case?
If you need a reset, it won't help,because as said before, ICS stock firmwares don't have recovery
From my funky phone
here i am,i tried,download went ok but cell is stuck on lg logo
with vbscript i managed to run r&dtt and change country to diferrent but on 90% always cuts me off,i noticed in device manager that it cuts usb connection,i know that i must put cell on usb debbuging mode but i cant when my cell is completely locked when its turned on,is there any solution for this or we can say i can through it away??
well, I don't know what to say friend. if smartflash fails, other ways will fail too. you may try r&dtt with the shttp tip. I'm afraid this is the last chance
Hmmm, what if he tries to flash a stock ICS? Since SFT tries to reboot in recovery mode, it will wipe data, and maybe will help...
As long as it doesn't drop the usb connection, of course

i used v30b and sft download complete and it turned on lg logo and stays like that,no reboot, with shttp tip i tryed again but it always cuts me out on 90 %, do you guys know if i take it to a special shop for mobile they could reset it with some special cable or something????
when download on smartflash completes usb immediately disconects me and than cell can not reboot,smartflash automaticlly finds a com port,do i need to do something manually with installing drivers or something?????
