How to get back from Custom rom to stock rom in few steps - LG Optimus 3D

Hello all,
first of all sry 4 my bad english...
I´ve read a lot of threads about unbrick / restore stock rom, but tbh with you there is a much easyier way to get back to a stock rom.. U dont even need win xp. I tried it with win 7 64 bit and it workd perfect. I went back from Waterbear v1.0 to v10D without any problmes. Also you can unbrick your phone ( with a some luck )
Here we go.. What u need :
1. lg BC2AppSetup. exe from lg.com
2. lg mobile update
3. nothing more
ok now do this:
!!!!turn off storage mode in settings and turn on Usb Debug
1. Install bc2appsetup
2. run lg mobile update
(If this is ur first time using lg mobile update .. if not go ahead to step 5 )
3. Connect your phone to your pc so lg mobile is able to recognize it ( some driver will be installed, let your pc finish with that )
4.disconnect your phone from your pc and let lg mobile run, dont close it!
5. turn off your phone ( no need to remove batt or something like that, just let it turnt off ) and connect it to your pc again.
6. now wait for the batt loading symbol on your o3d.
7. while you can see the batt loading symbol press vol-up + power on for about 6 sec.. your device turns off and you can see some driver installed on your pc. ( there can be a popoff with missing omap4430 driver.. no problem just ignore it )
8. After installing the driver to your pc you have to press again vol-up+power on for about 6 sec. Have a eye on your lg mobile update during pressing the vol-up+power on button because u will see lg mobile is recognizing your device.. As soon u see that u can stop pressing vol-up+power on. Notice my screen didnt went on during this procedure.. But it works perfekt!
9. Now that lg mobile have recognize your device you can see that lg mobile update cant say what rom is installed and this is good! Because now you can just press s/w upgrade and it will upgrade(restore) to the newest stock rom.
You dont even lose your data..you keep everything but i recommend to do a factory reset in settings after all .
You will lose Root, superuser, cwm but you can get it back in few minutes without any problems.
P.s. As i said there are a lot of threads about reflashing stock rom but they are all much much to complicated. A lot of steps they say you dont even need as you can see here..

Will this remove. CLOCK WORK RECOVERY?
THANKS.

Need help installing gb baseband

Ok im on lg thrill,I have all my drivers install,I have the lg,omap,etc installed.I hold the volume button up and plug up the phone,but it does not show the "detected new hardware,I also try the volume up plus power button and still no work,i am on windows xp,Ive been trying to do this for the last couple of days,what am i doing wrong???????
Make sure to double check that you did everything and installed everything as stated in the instruction thread. Run flashtool as admin. If still doesnt work, and this is only way it worked for me, do the power volume up but remove the battery. Thats how i was able to install the baseband after 2 days of trying.

i just want to share what i did to flash GB baseband.
1. i uninstall everything that smell LG from my computer (pc suite, divx, LG smart world, LG flashtool)
2. install step by step everything from the beginning (except LG pc suite that come from the phone), then i install pc suite (2 file) that come from the tutorial page.
3. follow instructon from the tutorial page.
4. my computer didn't detect omap but LG modem, and when it needs the driver, i take it to omap driver that's been installed before.
5. change port and follow the tutorial.
6. when connecting to computer, first time to make it "ready"
7. second time connecting, i took out batterey first before connecting back to finish the flashing.
8. flashing and stop at 22% (GB "leaked" baseband), restart phone,..and the signal bar finally there.
PS : im using Win XP sp2,..sorry for my bad english

1. Do i uninstall the lg drivers also?
2. Do you mean the lg flash tool?
i did exactly the same as ssfirme , i found the original instuctions didnt work for me, i think for me the bit that made it work was removing the bettery before connecting it to the computer for a second time as this step isnt in the original instructions

[Q] think i bricked it good and proper

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

Help needed

hi have been trying to update to 4.0 via flash tool but ive tried everything and cannot get it to work......ive been trying for 3 days and ive pretty much had enough of trying on my own so i though id would ask for help.
ok firstly i am on gb 2.3 im running custom cm7 no probs but i wana take the next step 4.0 so....i have all lg flash tool etc and fast load etc all nessacary files needed but for some reason my phone wont connet and flash its doing my head in. i have it into download mode, battery out etc but after that nothing i cannot progress further its like the program wont connect/register the phone.
im running win7 i even looked into other post and thought this maybe the problem but i have already installed these when gone into download mode as said here If you plug your Phone on PC without battery, OMAP4430 device appeared for seconds and then disappeared in your Windows Device Manager
(check arsen4oo photo guide in post #3)
On windows 7 sometimes OMAP4430 flashes too fast so you cant install driver.
There is a a windows feature that will help you install the driver easier.
To view devices that were once installed but are no longer attached to the computer, open a Command Prompt window using the Run As Administrator option and enter the command:
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
Then, from the same command prompt, type devmgmt.msc to open Device Manager. Choose View, Show Hidden Devices. The new instance of Device Manager will show “ghosted” entries for devices that were once present. This technique is especially useful for fixing problems caused by leftover drivers after replacing a network card or video card—you can easily delete the ghosted device or update the OMAP4430 driver.e
i just dont know what im doing wrong
cheers in advance
HI,
Please uninstall all LG drivers, and start again. If you are using WIN7, run it with WINXP SP3 compatibility mode.
Getting the Software upgrade screen is tricky, the timing needs ti be just right for the screen to stay, else it blinks and the OMAPP difficulty starts.
You need to listed to the connect disconnect sounds carefully.
Its not difficult, just that the timing needs to be right for the battery to be inserted.
all the best

Make sure all the drivers from the guide are installed. (including omap driver)
Load the DLL and the rom to lg flashtool.
Listen to the port with LG flashtool's port settings. (One is enough , The icon with a printer cable that's the port settings)
Take the battery out but be ready to plug it back in.
connect the usb cable.
Hold volume up
You're gonna hear sounds from windows in this order ;
1.Connected
2. Disconnected
3. Connected (Again , when you hear this plug the battery back in)
If you did it right then you're now in download mode.
Go to the device manager , find the LG device (I don't remember the name , but there is only one so you'll see it.) and go to properties , advanced and port settings.
Change the port to com41.
Flashtool should take over and start.
For extra guidance , see xbsall's thread ;
http://forum.xda-developers.com/showthread.php?t=1942836
To enter download mode .
Your phone in your hands without anything :-
1- Pull out battery .
2- hold vol+ and keep holding .
3- Connect your phone and you are still holding....
4- Now the phone is connected and you are holding vol+ . Insert battery and keep holding for about 3 seconds . Now the phone in download mode (there are some korean words on the screen) .
That's all
Good Luck

Because you're flashing the baseband before you flash the ROM. Change the sequence , ROM first then baseband. (Just remove the baseband you added on the flash tool ".fls file" then add it again it's gonna be flashed after the ROM )
Edit : I can help via team viewer if you want.

[Q] LG optimus 3d p925g bricked

I've looked at the similar threads , to be honest even if one of the suggestions might work , none of the people seem to have the same problem from my understanding.
So apologize ahead of time as i imagine someone has bricked in a similar fashion in some thread buried somewhere.
But have an unlocked P925g lg optimus 3d, got a few days ago.
Last night i rooted just fine , root checker says it was rooted properly.
Then i installed rom manager as i was following manbearpigs post.
When i got to flash clockwork mod , i clicked the button and it looked like it was doing some flashing , but the phone turned off to reboot??
and now when i power on the lg logo appears and then the screen goes funny.
If i try to hold the power down and 3d button , i get a green screen . However i'm very unsure of what to do next.
However when i plug into usb the phone goes black , refuses to turn back on until i take the battery out.
I'd pay someone here if i could , but i'll take any help i can get.
Appreciate any help.
I don't KNOW, but just an idea:
May be your phone is stuck in download mode?
With this latest ICS (original, not ported) my phone shows black screen when in download mode (no message SW UPDATE and something in Korean).
Did you try to plug your phone to PC? Does your comp see it?
From what I read flashing wrong CWM might cause problems...
Also try to read Ressurection thread by xbsa, it helped me couple times
Don't give up!

My computer does see the phone if i take the battery out , and push the volume down while it connects. However when it connects , it cannot find drivers that it find originally.
I'd be happy just to have the phone back to froyo right now , however i am not giving up , just asking for advice. Will reply once i look at the resurrection post you suggested.

just try the LG flash tool to flash without reinstalling drivers, if it doesn't flash you have to uninstall all LG drivers, reboot your computer, install again LG drivers and flash Bin files using Flash tool, you don't have to flash Bin and fls files at the same time, first Bin file, if there is no network close LG flash, open it again and flash Fls at second time to get the right baseband (sometimes it not necessery to flash this fls files)
or just follow this guide

To get to download mode you need to keep battery in, remove sim and SD card. Hold vol+ and plug USB cable. You should see message SW UPDATE and some Korean. My phone now doesn't show it, just blank screen. But LG Flash sees it and u can flash bin fls.

Remove drivers and use the LGMobile Support Tool to install the drivers, if your phone is connected it should detect it and finish the install process. I believe the P925G is a Rogers device? You might have to select Rogers as your carrier to find the drivers.

ok so i've deleted all lg related material from my computer, when i connected the phone to the computer with battery in , nothing happens.
Without battery , it detects automatically , then it continues a loop of picking it up and dropping off .
So i moved to my laptop , attempted to follow the guide kupuku posted, however after getting the went logo on the phone , it never gets past that stage no matter what i do.
I've also tried LG support tool , it doesn't detect my phone on either my computer or laptop , even after installing/reinstalling the proper drivers.
LG does have a live chat which isn't open and the phone number can not be reached from my area.. i imagine its a 1800 number for asia or something as i do live in Canada.
My only other choice is to take the phone down to a guy that can get it out of boot loop for close to what i paided for the phone a few days ago.
Least to say , that option is something i want to do , nor can i afford to do.
once again i apprecaite the help that has been given , and for any that will be given.
edit:
Ok so i got lg mobile support to work by doing recovery and entering my imei number. Its currently at 4% but its been close to an hour and a half. Might restart and see if that works , but my phone is doing the logo boot repeat pattern still , even during this update. so not sure what exactly is happening.

[Q] Help me.. My Lg optimus one p500.. BRICKED ???

my phone can't Connect on PC i have instaled USb drivers properly....After removed a battery in kdz error on emergency mode phone won't turn
There is an emergency mode you can try as long as you have the software on your computer to flash factory settings on to your phone.
Toemergency mode:
1) Take out the battery
2) Have a usb cable already connected to the computer.
3) Hold the power button + volume up + back button AND then connect the usb while holding those buttons
Yellow screen will appear with the words emergency mode in the middle.
At this point, do some forum searching, find some kind of stock image file and LG program to flash stock system on to the phone.
**I DONT OWN THIS DEVICE** but i had a few cases and this should work for you too

Your device is hard-bricked. Your only bet in LG. Go to LG and tell them you turned it off, and now it doesn't start up
That thing happened to my phone a year ago. You can't do nothing at home. Go to a service.
