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

Stuck on S/W Upgrade Screen
Hi,
I, too, am stuck in the S/W Upgrade screen.
I turned my phone off and when I turned it on again I tried turning the volume down, but it turns out, that combination would lead one into the S/W Upgrade screen (sorry, noob). And now, I'm stuck at the S/W Upgrade screen. I want to turn it off again, but a friend of mine tells me not to because it might brick the phone, is that true?
My phone is not rooted.

I just pull the battery. Done that many times. My o2x still in good condition.
Thanks loads!
I've been contemplating if I should root this or not. I might though, when I get a free time. )

serious problem
Hi,
I tried to update my LG optimus 2x to android 2.3.4 but I forgot to turn "windows
Enabler.exe" ON and "UpTestEX_mod2_marwin.exe" stuck on upgrade stage at 4% so I just closed "UpTestEX_mod2_marwin.exe" and unplugged my phone. then I turned it (I exactly followed the instruction for upgrading in website) and phone stuck at "S/W upgrade ....: window. then I downloaded and followed the instruction for flashing the phone but after pushing "flash.bat" it stuck at "nvflash started" command and didn't happen anything after 25 mins so I stopped the window. then I tried recovery (push vol_down then power and release ...) and after opening up "Android recovery utility" I could go up and down on menus but I couldn't select it. I'm really confused what to do and will be really grateful if somebody help me.

Hi, I think i bricked my P970... ;(
I was on V10a with CWM installed. I tried to update my phone to V10b via FOTA in the main menu. Phone downloaded firmware update (approx. 7MB) and rebooted into CWM recovery. It stuck there. Tried to reboot, wipe data, but it still loops into CWM recovery.
Finally i tried emergency restore via LG Update. Whole update process looked fine until reboot.
After that I'm stuck on grey screen saying Firmware Update, After firmware update phone will reboot, blah blah blah, with empty progress bar. Nothing happens... Sometimes there's blue screen (kernel panic?).
Is there any chance to revive this phone? Please help...

Go to the P970 Firmwares Flashing thread and read it with calm. Use method 1 tutorial to flash a newer version, from 10B (the ota update) to 11B.
Good luck.

:S I just did it 5 minutes ago with 11B because I bricked mine, and eventually succeeded. It must have broken really hard... You'll have to visit LG center I guess...
Sorry
I was upgrading from V10a Orange PL to V10b Orange PL (with fixed root exploit).
After I bricked it, I was trying with KDZ FW UPD with every version: Orange V10a, V10b, V10b EUR Open, V10c, V11b and there's always this grey screen saying "Internal firmware upgrade. Phone will restart after firmware upgrade (from Polish) with empty progress bar with flashing buttons? Don't know what to do...

I've never seen that screen. It has to do with the FOTA, which I think you should have never done if you were rooted. I'm sorry, but it looks like you will have to deliver it to the store if anyone else can help you.

Yes it's my stupid mistake, i was updating via FOTA with rooted phone.
It's too bad that OB doesn't have key combination for recovery. I think there's nothing else but trying to return it to my operator. I hope they'll fix it on the warranty...
Hey man have you tried to take the battery off sd card off everything off and connected the phone to pc via usb thile pressing vol up button? It should appear S/W Upgrading screen.

Yes I did. I'm always flashing with method 1 (UncleCacker's), without battery, SD card and SIM. I also tried emergency restore via LG Updater but nothing helps.
EDIT:
I gave up... Phone is at my local store now, waiting for warranty repair...
EDIT2:
Phone was repaired at LG repair center. They replaced motherboard from AORPTL (Orange PL) with simlock to APOLTL (Open Europe Poland) without simlock so i have luck.
Received my phone in the end of August.

No exploit will work... LG fixed that.. damn lg
Anyways why did not you search before, there are a no of threads regarding rooting.
Use cwm injection method and flash your rom again. http://forum.xda-developers.com/showthread.php?t=1512203
By the way you should try other custom roms here as well rather than stock.

First of all, since you're new to this board please read the Welcome To The LG Optimus Black Section..... (Please Read If You're New)
Also, read the [HOW TO]The Big N00B how-to! since it will answer most of your questions.
Second, if you would have searched you would have found your answer already, but i'll help you (i'm in a good mood today too ).
You can find an already rooted v20E firmware HERE.
Just follow the steps from THIS post but instead of using the V20B firmware files use the ones from the V20E firmware (i've already given the link to the V20E above).
Good luck and happy modding

Smartflashtool has stopped working
Hi, my OB also has v20E firmware installed by default. I 've tried to root the phone by using smartflashtool method that has already been described above. However, whenever I tried to root my device, it always ended up in failures. The smartflashtool program either showed "Timeout error is occurred" (sometimes) up or "Smartflashtool MFC has stopped working" (most of the times) at various points in the rooting progress
I used all of the programs mentioned on the posts above but still no luck
- Installed LGSmartPhone_ModemlinkDUNDrive_WHQL_ML_Ver_1.0
- Installed LGWindowsMobile_USBDriver_WHQL_ML_Ver_1.0
- Installed LGUnitedMobileDriver_S4981MAN36AP22_ML_WHQL_Ver_3.6
- [patched]V20E_SEA.bin
- V20e_SEA.fls
And currently, my phone cannot boot into the main phone screen (it can only display LG logo at best). Please help!

Hi, thanks for your reply. Unfortunately, I haven't gotten to the point where the phone was rooted successfully (100%), whenever I tried to run B_SmartFlashTool_Extern.exe, it always ended up in error. What did I do wrong? I've used the appropriate files and installer, haven't I? Now, I'm totally freaked out because my phone has run out of battery and doesn't show any sign of charging even though I've connected the charger
Oh by the way, I've already used the patch rom for V20e, but still no avail and already tried running the program with admin rights

Question about root
Hi, I just root rights to V20O not only to root recovery, how to do it. Recovery mode without dissolving it.
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

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.
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?????
