my p920 is dead after an update to ICS with lgflshtool. it is off and there is never started.
I completely lost all the boot. There is an alternative method to omap4boot or os_hacking? they do not work for me.
driver, cable, battery is ok.
the problem is that I can not have in any way the COM port and the LG logo on the display. fastboot stops and gives me errno: 121. no dowload mode in any way. appears only OMAP 4430 TI board.

I can not in any way to see : LGE CDMA USB Serial Port.
tried it on 5 different computers (XP-SEVEN)
Did you uninstall all things LG from programs and features? Did you reboot the PC? Did you run the omap installer? Did you install the LG Drivers? Did you reboot pc again after that? Did you connect, the phone with no battery and volume held up? Did you then force the omap driver to install? Then did you disconnect the phone and reconnect it again with volume held up and let the LG drivers install? Did you then change LG CDMA port to COM 41?
If you did all of that....
With fastboot did you take the battery out of the phone? Did you connect the phone by usb with volume held up, no battery? Then did you let go of the phone? Did you then insert battery when it says 'wait 5 seconds?'
You can do it on 1,000 computers 1,000,000 times but if it is not done correctly it will never work.

yes to everything, BUT NO APPEARS LG CDMA PORT.
I always unzip everything on my desktop. perhaps this could be a problem?
one question:
have you ever had the screen off and no vibration in any combination?
another question:
You write in point f4 unistal OMAP4430.
because you need to uninstall OMAP4430 if it appears in TI BOARDS? maybe that is my problem? seems to me always and only in TI BOARDS!
QUOTE:
f4)Look for "OMAP4430" blinking on and off in Device Manager with a yellow question mark under "Other Devices." (You can let go of the phone). If you do not see it, look for "TI Boards" blinking in device manager and quickly open the arrow. Then uninstall that OMAP4430 (right click, check box to uninstall device and driver, confirm), disconnect phone and reconnect with volume up. Then...
If it has been installed incorrectly in the past, the omap device may need to be uninstalled under TI boards. Then catch it under Other Devices and point it to the right file to reinstall it correctly.
This is only one way to do this that I wrote because it is what has worked for me.
The omap4430 utility Dr. Mario mentions probably helps to do the same thing, but I have not tried it.
one question:
have you ever had the screen off and no vibration in any combination?

ok i need help please , i had gbread on it and installed superoneclick to get root then tried to flash cwm with vipermod. message said out of storage space or something (dont have ext mem only internal)and now phone will not turn on.
have followed this guide http://forum.xda-developers.com/showthread.php?t=1244490 and phone was recognised by omapp but couldnt change the port in device manager and couldnt find a bin to download so i tried to flash a kdz v21a
clicked start on lgflasher but nothing happened so after about 5 mins i cancelled it thinking without the port change it was a waste of time.
now i cant even get omapp to flash up when i connect phone . device manager refreshes but i cant see anything change .
hope thats enough info for some kind person to help.
many thanks in advance

Where did you get vipermod from? The Transformer Prime forums? That's meant for the TFP and would not have worked with the O3D since it flashes to mmcblk0p4 rather than mmcblk0p. You should have used the flasher here.
Download this, this and this. Extract smartflash.zip, install both driver packages. Then, run Windows Enabler, in the notifications bar, click it and make sure it is set to 'on'.
Now remove your phone's battery and sim card, press volume up and connect your phone to the computer. Hold volume up until it is detected by the computer. It should take no longer than 20 seconds.
Now run B_SmartFlashTool_Extern.exe, go to rom copy d/l, select LGP920_CP.fls for CP bin and LGP920_AP.bin for AP bin. Make sure under communications setup that your phone is connected (verify the com port in device manager) and then click start. If all goes well, you'll have a stock v21D phone again
Thanks for the help guys but i'm not getting a com port when i connect the phone so i don't think i can use any of those methods . or can i
i want to go back to the beginning and see if omapp will detect phone and install drivers but i can uninstall the installer but dont think that will remove the drivers , does anyone know how to do that.(cos i think i messed that bit up )
thanks again
marty
vipermod , i think i followed a link somewhere in the o3d forum where someone said u could use it to flash cwm
so , i uninstalled all lg drivers uninstalled omap installer searched registry for for any mention of omap and deleted (some wouldnt delete ) .
restarted computer (xp by the way )
then installed omap installer and lg drivers and connected phone holding vol up
and................. NOTHING whereas yesterday i had a little icon in the task bar and the opportunity to install omap drivers.
conclusion , phone is dead , i had an oppurtunity to fix it yesterday and i blew it
hope someone tells me i'm wrong but its not looking good
marty
take off battery and just put your usb cable and tell us if it shows omap in your device manager
dont press keys
if i connect phone without battery device manager just refreshes a couple of times but nothing changes with regards to ports doesn't matter if i have vol+ button in power button in or nothing
thanks anyway
marty
am i getting somewhere
update : ok so i'm on a clean install of xp and i connected the phone with vol+ and it wants to install omap4430 drivers. is that good news?
i installed omapinstaller , then the 2 lg drivers ca and ma , then reconnected the phone and went thro omap driver install but still don't have any ports in device manager
is there no way i can force it to flash without it having to think it is connected cause if its recognising it as omap4430 there must be something there
don't want to give up on it too easy , if only i put this much effort into it whilst it was working lol
marty
evening all . new update
tonight i've installed the lg support tool and drivers and found that if i leave my phone connected i occasionally get "TI sample boards" popping up in device manager for a couple of seconds without having to press buttons , unfortunately it doesn't stay on for any longer with buttons pressed.
i was wondering how to force install the "LG CDMA composite usb device " drivers cos its never asking for them as it should according to the tutorial
hope someone can help cos i've seen a few threads with same problem as me

Dude don't do anything drastic. Is imap flashing on and off when you connect. Many have problems with getting into download mode. You have to do it just right.

the easiest way is to just download the software update LGMobile support tool
http://www.lg.com/uk/support/mc-support/mobile-phone-support.jsp
launch the software. Take out battery, attach usb to pc, then hold volume up and power at same time, the software will see phone, select customer support then recovery or something like this – type IMEI number and then software will just re download and flash the phone to repair. the phone will have power for the flashing via the usb. when it finished just re attach battery and turn phone on.
If omap4430 keeps connecting and disconnecting,neither lg flashtoor nor lg mobile updater will help in this case.
You need to find a 2nd stage bootloader for the phone or see if LG agrees to repair it.
btw I'm in the same boat
Thread will be moved. Based on the fact it's not:
A ROM [X]
Mod [X]
Kernel [X]
Thank you for your compliance, hope you get your phone working.
If someone could modify the omapflash tool for o3d,the problem would be resolved.
thanks for all reponses, and and how could solder the USB cable? what tools I need or where I could do?
if it keeps connecting and the disconneting try this. attach usb cable to PHONE only then take your battery out, then put battery back in and quickly press volume up button and then attach usb cable to PC. keep hold of volume up button all time dont let go and install all drivers omap, usb driver etc.
hope it helps

I have the same problem........i bought this phone long time ago and i just found it while cleaning my room........i thought that maybe i should update it since its still running Gingerbread.....i tried almost everything but nothing seems to be working...omapboot is not working, lg flashtool is not working...the phone is not showing any signs of life.....the only time it responds is when i connect it to my pc and it shows up as OMAP4430 TI Board.....
HELP NEEDED, I dont want to loose this phone
Hey,
my phone was stock gingerbread v21e when I decided to try ICS. After all I got it working but was not really convinced. So I tried to downgrade to gingerbread again. First try everything was working, except one thing: When I enter the download mode it shows the korean letters, still. Is it normal or have I done a mistake while downgrading?
Sry for my bad english
edit: I used the LG Flahstool for everything and the Resurrection Guide
I've got this problem, too
it's normal you have downgraded
I had the same, when i downgraded still everytime when the download screen apeared the korean was there.
After downgrading a ran the official lg tool, it updated to v21e, still korean download mode. Then i flashed the files out the downgrade the undowngradeble topic.
That solved it
Don't ask me why:laugh:

use wkparks omap4boot, it will enter fastboot for you.
Install newest lg drivers, and have omap drivers ready, go to devices then plug your phone WITHOUT batery in the usb port, omap will flash three times.
You need to click fast, first flash i opened the device properties, second flash i opened driver settings (then the actual driver not loaded message dissapears, just wait. third flash (you're still in the driver screen) click as fast as possible on the appearing driver fault line.
Then manual search for driver, the go to your omap drivers folder. instal amd64 for 64 bit (doesn't matter which procesor your pc use) if on 32 bit, install the other.
thats's all
ps i'm on a dutch system so i've translated the device screen as best as possible, but i don't know the real names. So maybe you've need extra clarificfation
Every time I try to install the drivers manually, it just shows the message "drivers could not be installed". Doesnt matter which folder I chose. Is it because Win 64 bit? I read that OMAP drivers are not compatible?
On Win 32 OMAP doesnt show up, maybe after a reboot, ill try tommorow
Okay, I got OMAP installed and the fastboot program recognizes it. But when I remove the USB cable, no LG logo is coming
when you've started wparks omap prog, choose 2, then in your screen there's a message, wait 5 seconds. Then put your battery in. no you should enter fastboot mode. It's not neccesary to remove usb cable, something i've experienced. But what works for you
I did it, problem was LG COSMO wasnt installed... (Im an idiot ) How can I test the Downloade Mode Screen?

I previously had continuing connect-disconnect cycle. But I managed to install all the drivers and connect to my P920.
It's possible wrong drivers has been installed, try to uninstall them all and restart your PC.
Are you Using Windows 7? try XP.
Make sure that the battery is taken out and you press and hold Volume+ button for several seconds while plugging your USB.
If you open Device Manager you can see OMAP4430- device appearing and disappearing. Try to rightclick on it when it's appearing (takes some practice) and then select properties in popup menu. Then Uninstall device from properties and update drivers to factory LG and Texas Instrumental USB drivers.
If nothing works you might want to try USB JIG cable with 910K resistor.
Good luck!
Thank You ^^D

Hi everyone,
My P920 is bricked into a bootloop buy I can't even try any tutorial because the conection between the computer and the mobile isn't stable. I installed a few times the drivers, there are correctly and Windows get the device as OMAP4430 in the Device Manager (so, it's ok). But never stop to appear and disappear, connecting and disconecting everytime.
I've been looking for a solution this days but I didn't find any help,
Any idea of what should I do?
