Big problem.
I had CM7 #107 installed, flashed http://forum.xda-developers.com/showthread.php?t=1223846 to OC and fix a few things. first couple of days were okay, now phone reboot when ever and after reboot LG home crashes. so i tried to install a old recovery CM recovery, i had three and none of them worked.
I first cleared both caches and then did recovery. and nothing. cant access the LG recovery screen (with battery out, screen just flashes and loops) and now after flashing a stock rom via this link: http://forum.xda-developers.com/showthread.php?t=1021554, now i cant access either LG recovery or CM recovery as the last flashed deleted it.
Any one have any tricks or ANYTHING i can try. i wana revert back to STOCK! COMPLETLY STOCK. HELP guys im outta options.
UPDATE:
I think i bricked the phone, not sure how, but, cant access any recovery functions. cant even get teh S/W menu, it just loops. if i power on the phone the LG screen is just there, bottom menu buttons light up when i touch but no function. Also when i plug in USB computer makes a sound that i plugged it in but, LG software or any flash software cannot see the device. NEED HELP.
no one has any idea what i can try?
Search for the nvflash. I thought I bricked mine to, but nvflash helped me out.

i tried to use the nvflash tool but i cant get to the APX mode, when i hold both volume buttons and after connect usb cable, i hear the computer recoginizes that something connects, after i use the nvflash.exe --sync which comes up, but after i try nvflash.exe --dl bootloader.bin, it just hangs, it just says NVFLASH started, i waited 15-20 min and nothing.
try smartflash
I had some problems with Win7 x64 a couple of times. Have you tried with another computer?

UPDATE:
Using Smartflash -- how do you install rom using this program. i thought this program is only for baseband updating
Try this: http://forum.xda-developers.com/showthread.php?t=1229407
It includes the drivers for NVFlash, which I assume you're currently missing.
^^ thanks but i cant use NVflash, im in APX mode and i'm able to sync using the NVFLASH --sync command, but when i try to BL a file it just hangs on NVFLASH STARTING, i leave it for a while and nothing happens.
That's happened to me before, I tried a few times and it eventually worked.
i use nvflash.exe --bl fastboot.bin correct?
If you're talking about the link I gave you, use the batch file, it handles the command for you.
If you want the actual command, edit the batch file and c'n'p it from there
i edited the batch file so it only does the internal flash, all i get is "nvflash started", this suppose to take a while?
** i know the nvflash is working or supposedly, cause when i disconnect the cable i get an error in command.
No, it should be near enough instant if it's going to work.

There is a certian flag you need to run commands with, if your not running them as the first command. Try looking at nvflash --help
UPDATE: IT WORKED!!!, went home, plugged everything in, and on first try it worked using the .bat file. Now i have cwm recovery.
I'll upload the stock boot rom onto an external and flash using recovery. wffffuuu, thanks guys.
GOOD NEWS! Unless your power button does not work, the Revolution IS unbrickable! After searching far and wide for a method to unbrick my phone from the lg boot screen, I found a way! By now you have hopefully been to all of the other threads and downloaded and installed LGNPST and all of that hoopla so I will just post links and not full directions...here we go:
1) Download and install LGNPST and associated files
forum.xda-developers.com/showthread.php?t=1337386
http://forum.xda-developers.com/showthread.php?t=1466655
2) Follow directions all the way through step 11
forum.xda-developers.com/showthread.php?t=1337386
3) Remove your battery and connect your phone via usb (the hard buttons on the bottom of the phone should blink slowly).
**Make sure battery is at least 25% charged
4) Hold down power + vol up.
5) Phone will come on and read "downloading do not remove cord" or something to that nature. Put battery back in.
6) If you followed step 2 correctly, LGNPST will now show an unknown device and will be in emergency phone book mode. Under the emergency tab it will ask you for 1) a .dll file and 2) a phone book. Click on the folder icon next to .dll file and load the VS910.dll from wherever you have it saved. Click on the folder icon next to phone book. Navigate to the folder where you have saved the correct .tot file. in the "file name" box type *.* and hit enter. If you are in the correct folder you should now see the .tot file, click on it then click "save".
7) Back on the LGNPST screen click on start. It should now say MASTERBIN and a percentage ticking up (if not you have done something wrong).
8) once completed commence re-rooting!

special thanks to:
mtmichaelson for his awesome root package!!!
jackpot08 for LGNPST
and all of those who have kept the .tot files movin'
I hope this helps!!!
Good post, this method does work as a last resort, but be warned.. flashing a tot file from the emergency download mode like this will most likely get you stuck in "test mode" -- no more usb mass storage (and possibly other problems).
And so far noone knows how to get out of test mode...
All it took was a simple google search...

Broken link to a "fix" that is more of a bandaid than a fix, as it requires you to downgrade to froyo.
Sent from my VS910 4G using XDA
Yep.. believe me I searched... and searched and searched until my eyes almost popped out of my head
Nonetheless I'll take test mode over a bricked phone with a fresh 2 year contract any day...
Links for this AND instructions are posted in like 3 other threads lol.

You do not have to go through all that if you have the proper drivers.

Replace your lg revolution for free
Flashing to v4 froyo tot will not leave the the phone in test mode or rooted. If you can get your phone back to froyo with no test mode then you can bring the phone back, and tell them the phone will not update. I have had two phones already and for some reason they will not take the ota updates. The carrier had no idea I rooted/unrooted and flashed oh so many times. Just a suggestion for noobs who do not want to spend hours or days or maybe even weeks trying to get this phone to work correctly.
Help please
I have tried above and I cant seem to get drivers to install properly
The only one that installs properly is USB Composite device and the LGE CDMA USB does not install properly. I flashed wrong recovery from ROM Manager and stuck at LG screen. LGNPST does not capture my phone. What else should or can I do besides take it in?
drivers
i put both LGAndroidDriver_Ver_1.0_All and LG VZW_United_WHQL_v2.4.1 and they installed correctly is ur phone stuck or can it boot
unbrick Lg revo info
I downloaded the files and had an issue extracting the rom .tot file , How do I extract the .tot so I can use them with the LGNPST.
I have followed the directions and found The LGNPST program comes up blank with no phone info. I am guessing it is because of the .tot files not being "extracted " . I sure would appreciate some help on this one. My phone is bricked.

When you download the .tot file, it should be a zip file. Just extract the zip file using WinRAR or 7zip to somewhere it's easy to find.
If it's not a zip file, then chances are it's already extracted and you don't need to do it.
If LGPNST is coming up blank even though your phone is plugged in, then you need to install the correct drivers or try a different USB cable or a different USB port because it means LGPNST can't connect to your device.

I can't get it to internet connection because i can't boot into anything . It is like it is stuck at boot. also the .tot files do not extract with any zip program . I have loaded the vs910.dll and the drivers onto my computer but the LGNPST program still not recognizing any phone. for that matter the the computer has not recognized the phone , maybe due to I cannot set internet connection mode. The USB De bug was enabled before all this started.
The whole situation of not completing boot came about when I happened defrosted the astro file manager app. Help

I had a few issues with this namely Tots not loading right getting perm black screen, I pulled the batt, put it back in and did a hard reset (wipe) back to stock then rooted added CWM with MT's hlep of course and am now re flashing gingervolt to broken out 1.1 and still puts me back in test mode, even restoring older backups put me in test mode, only v4 seems to work....WHY?
Thanks I finally got it back running with the LGNPST , tot version 7 . The phone works now but I also am in test mode and cannot switch my usb. Question, Can I use The LGNPST and select tot version 4 and install that as before to get my usb back. And if so will I then be able to get OTA updates or will I have to return it to store for that. I hate being stuck in test. What happens with phone stuck in test ?

You'll be able to get OTAs but you'll still be stuck in test mode. To this day there is no known method (yet) to get out of test mode. Someone correct me if I'm wrong but the only difference I know of with test mode is that you can't transfer files via USB cable anymore. You have to either use adb or an adapter for your microSD card to your PC.

Check if you have the latest drivers, connect the phone in recovery (vol- and connect to PC), flash with LGFlash Tool.

There is no other way...
Did you follow the tutorial? Did you remained calm and gave time for windows recognise your device?
Did you uninstall and re-install the drivers? You're able to reboot in SW mode (vol- pressed while connecting to PC)?
Here you have all files needed:

Delete your old files, download new ones and follow the tutorial.
Remember to remain calm and give time to system recognise and install everything needed.

TNQ...I fix my LG...and know work perfect I put 20A kdz. 4.1.2. and phone work perfect
Same problem here
I have the same problem. I think the stupid thing I did was to install V20a without rooting the phone. Now I cant root it. IS11LG_SystemBackupTest.signed.ap would not run and when I try to recover either with LGflashboot or LG firmware recovery I get the same error message "morning call is empty" (very strange error message). I can go back to v20a but since I am not completely happy with it I would like to resolve it. Is there any chance to fix it? I am not very confident to format bootload or installing custom ROM.
Thanks

You cannot root the phone on V20a using IS11LG_SystemBackupTest.signed.apk, since that file is used for versions V10x. Check out this link for rooting V20a: http://forum.xda-developers.com/showthread.php?t=2180688

Uninstall all drivers and folders like "LG United Mobile Driver" and "LG USB Modem Driver".
Re-install the drivers:

http://www.4shared.com/file/ZSMf2x6n/LGUSBModemDriver_Eng_WHQL_Ver_.html
Take out the battery, press "Power Button" (just to discharge all phone components), put the battery back on the phone.
Press "Vol-" and connect to PC. Wait while windows detect the device and search in windows update for possible new drivers.
Windows won't find a thing but will take some time while trying...
After that you should be OK.
Just did similar to my phone and followed the advice in this thread - now sorted. Thanks guys you rock!
if u epic fail to manually force the drivers in just install android jdk open it and update it.

Well My sister and her boyfriend were trying something whit her phone, I dont have a clue what the hell they were trying, at the end of the day, she comes to me with her LG P970H with the screen S/W Upgrade please wait while upgrading.
I try to Connect the Phone to the PC with the battery and The Pc makes a Sound and says that the USB is not recognized.
I connect the Phone without Battery And the same happens, Sound and not recognized.
Connect Pressing the Vol - , Same happens
Connect Pressing the Vol + Same Happens
Connect Pressing the both buttons with and without the battery Same Happens.
Allright then its the drivers, I go Ahead and download the Lasted Usb Drivers from LG, Try again and nothing new happen.
Download some Old Usb Drivers, Same thing nothing new happens.
Why and When does the S/W upgrade Please wait while upgrading screen appears. I think I can install another OS or make a Hard reset on the Phone if i can get the PC to Detect it. Its not the Cable and its not the PC. Tried 3 diferent cables and 2 pcs and a Macbookpro. I live in mexico and im phone company its TELCEL if that helps.
It appears as soon as i turn on the phone.
PD: please if you know what im dealing with , write the answer for dumb people like me, its hard to know what you are talking about when using names like ST, KDZ and stuff and english its not my mother languaje so dumb it for me. THX!
You must read this.
And you need the bin and fls from KDZ to extract and root your device(if you want it rooted). Since here you should look for yourself.
A soft reset is keep pushing Vol+ + Power for 5 secs.

I think the phone was rooted i really dont know i think they were trying to update the system. I tried the Soft Reset Nothing happens, I think its not charging anymore it will only turn on when i connect the Usb cable. I tried removing the battery for 10 mins and tried again all steps. My Problem its that the pc Detects that theres an Usb, but it wont recognize it.
After i plug in the usb cable to the phone and i disconect it, it will remain with S/W upgrade screen for a few seconds before turning itself off. I cant turn it on by the power button.

Just press F8 during bootup. if you get a promt fo selecting boot-device, press enter and quickly hit F8 again.
when System is booted remove the Batterie, press and hold vol+ and connect to usb (Batterie is still removed)
now my OB was detected with S/W Upgrade Mode

Are You sure you disabled Driver Signature Enforcement.
this must be done every reboot you do or your phone will not be recognized in S/W Upgrade Mode. After flashing with SFT it is not needed. Only for flashing in S/W Upgrade Mode.
The currently available drivers work fine with x64...
I never used SFT on x86, and I never had a problem. I didn't even need to disable driver's signature enforcement, ever.
What's weird here is that his phone boots in to S/W upgrade mode without any key press. It seems to me that now you got there a flashlight...lol
Hi
I've been reading all the topics in here and trying many methods, but now im desperate, so i dediced to post here
When i try to run my phone the red text appears: [LG-Security] Error: Boot Image Signature!
I've tried to run http://forum.xda-developers.com/showthread.php?p=35971349 this guide, but when i plug off my battery i cannot get into s/w upgrade in my p880.
When the battery is plugged in I can run s/w upgrade, but my computer doesn't see the device.
Is the phone bricked?
Can i do anything to ressurect it?
EDITroblem solved - still don't know how, but after 5000th reboot it is just working without any other bugs etc...
it's bricked, you tried to install custom recovery without unlocking bootloader?
you can revive it using that tutorial. leave the battery in in order to get to s/w upgrade screen, but before that, you need drivers (and if your computer isn't detecting it in s/w mode, the drivers aren't installed)
It seems that you didn't install the proper drivers on your PC as it doesn't recognize it.

Yes, your device is (soft)bricked, and yes, you should be able to recover it. Try the LGMobile Support Tool. Run the tool and plug in your phone while holding down the volume down button (with or without battery). If it doesn't see your device, make sure you have all the latest drivers for your device installed. You can find them on LG's website. Then, try again and once found you'll have to force an update. You can find that option somewhere in the top right menu's. Then be patient.
I seriously doubt whether you have properly searched the forum, or Google for that matter, though..
