After 4 hours of searching for solutions on my own, I am hoping someone might have a solution.
Rooted and installed latest TWRP no problem.
Flashed the CM 10.2 (official release), and phone rebooted and hung on a fastboot screen (last line [1170] fastboot: processing commands)
I've come to find out that I flashed the 802 version of CM 10.2 and not the 801.
Now, no drivers allow my phone to be seen by adb, nor my pc. I've tried many (800, 801, etc.) , including the LG firmware update tool mechanism for the same.
Nothing.
I can boot into TWRP, but have no backup file on my sd to flash back to normal.
I can boot into download mode, but the phone still will not be recognized.
No I am trying the R&D test tool method, but I have a feeling that this won't work either.
Any words of wisdom, other than I'm an idiot for flashing the wrong rom?
Do you have a microusb drive? Or a USB otg cable? Load a proper ROM and see if it helps

Just made an account so I could reply that I am having exactly the same issue and cannot figure out what to do. I've tried every different guide I could get my hands on and none of them seem to work.
Had same issue, i used R&D method and, it worked.
Guys, thanks for replying. I've tried the R&D method, but it sticks at 49%. Have not tried a pc with XP yet. I'm pretty sure there is a solution, but you have to wade through all the posts and decipher best you can. I can't say enough how important it is to read the entire thread before doing anything. Anyway, I'm still working on it. In the meantime I bought another G2. :

On my phone, can not boot into recovery mode. No matter how many times I try to use the home and power button. I even went to youtube to watch a video on it to make sure I was doing it right.
I have installed clockwork recovery via fastboot many many times, using different versions. I also have tried it with different roms installed.
I wonder if it is because the first rom I installed was superfast froyo, which says recovery is not working. I also installed swiftdroid 2.0, which also wouldn't let me use recovery. Though I forgot to try to reboot into recovery from the android menu when I had swiftdroid installed.
It's not a big deal anymore, since I accomplished what I wanted. I installed Froyo Optimum V3 with data2system via fastboot, and it worked fine. I now have 245mb on the phone so it is all good. When I installed it I just installed boot.img, cache.img, and system.img each to their respective partition, and data.img to userdata partition. So far, everything works fine.
However, it does bother me a little that recovery isn't currently working, I'm sure I'll find the answer sooner or later. Anyone have any ideas?
Hello as I can see you recently uppdated from stock 2.1? Then something went wrong and you used a rom that does not support recovery. Please tell what .kdz you flashed

All Fastboot ROMs support recovery regardless of their version.
Try this:
Go into fastboot and open a Command Prompt and type:
Code:
cd <location of SDK Tools>
fastboot erase recovery
fastboot flash recovery nameofrecoveryimage.img
fastboot reboot
This fixed my problem I had when I first flashed fastboot onto my GT540, don't know if it will work for you or not, but its worth a try
Hope it helps,

I think something did go wrong during the initial upgrade to 2.1. I forgot to mention a couple of things now that I think about it.
I used this link for most of my information:

I first installed the european rom listed in that thread via KDZ. I never get an LG screen during boot up. I don't remember if the stock 1.6 had an LG screen or not. I think upgraded to what was then called "super fast froyo 2.2." I then wanted to install a rom with data2system, when was when I realized restore wasn't working. I then tried to downgrade back to the european rom via KDZ. It didn't work. Whenever I booted the phone, all I got was a black screen similar to the fast boot screen. I re-installed the european rom via KDZ, same results. Installed "swift droid 2.0" via fast boot, no recover. Then I installed I installed Froyo Optimum V3 with data2system, via fastboot, which is where I am now, still with no lg screen during boot-up.
Thanks you for your help, and i will try the link posted by JackG256 when I have time.

Actually the link you see was the one posted by me lol i recently posted on my reference guide thread aboutcases when you brick your phone and possible fixes, there is one for your problem.
Also as i have read plenty about this kind of things i can assure that not all the kdz with fastboot support recovery that is a myth , there is a recovery_rom.kdz, there is out.kdz and other .kdz roms that has a purpose.
My theory is that not all the LG GT540 are the same thing, why? because simple if you read all the threads of users that have had issues with their phone saying this ROM worked for me and then another user saying that it didnt for him but other rom did the job. There are so many .kdz ROMS and even more are been released, but modified to support fastboot and recovery.
So if you do a bit more of research you can find original stock .kdz roms and their modified version requested by many users marginalized because of their location.
Hope you fix yor phone with the one posted in my thread, good luck! you will need it.
I think you are correct about not all gt540 are the same. I have an "international version." When I was installing drivers, it was a very complicated issue, and most of the drivers I found didn't work. I had to use the drivers supplied by LG via their lgmobile update program, to get my phone interact correctly with my computer. Luckily, I have alot of experience with flashing and custom roms for other electronic devices. So I know how to handle bad flashes, and other problems for the most part. Right now, my gt540 is fine, no recovery, but the custom rom is working just fine. Next time I want to swap out custom roms, probably when the android 3.3 builds become very stable, I'll play around with some KDZs and try to get recovery working.
Thanks for your help.
If you want to try with more kdz then you should try with one modified by mur4ik for data2system method.

Just switched over to Tmobile from Sprint and before even signing into google i went ahead and tried to root my phone. Rooting was a success. Used Flashify to flash twrp recovery. Downloaded rooted stock D80110G rom and began debloating it (like I did with the Sprint version) and then booted to recovery, wiped twice, flashed and reboot. Well, now it will just keep rebooting back to recovery and thats it!
I still have access to download mode
still have access to custom recovery
Did not do a nand backup unfortunately
cant mount in twrp because computer no longer recognizes phone!
shows up under unknown devices as LG D801
Tried the stock recovery using LG Flash tool posted in generals but ran into the "can not update because of your device policy" or something like that. Reinstalled and tried it again many times, even switching languages and countries (the last step)
Tried using the ubuntu method posted by partager.info but even ubuntu does not recognize the device. Matter of fact nothing even happens when i plug the phone in.
Tried reinstalling drivers, tried on 2 different laptops (one windows 8.1, one windows 7, and an ubuntu usb boot) and my desktop computer (windows 8.1) and am just unable to mount using twrp because none of them recognizes it!
tried using the adb sideload but twrp just stays trying to load adb sideload forever and adb terminal cant even find the connected usb device.
Tried factory reset but that just takes me to twrp.
I've redownloaded the rooted stock rom and left everything as is. I'm assuming I just need to get it onto the phone somehow so I can flash it.
I have an otg cable but not quite sure how to work it wit twrp or if that's even an option; I've just purchased it.
I feel like I've exhausted my options. Anything else I can try?
Thanks in advance.
EDIT: Should've just used Titanium to debloat instead of trying to do a fresh install! I know I know
Figured it out! not sure how to delete this thread now

Hey sorry, I haven't been on the site for a couple days.
I used the flashtool to go back to stock. Had to enter download mode and work from there. The big issue I was having was a driver issue. Uninstalled every driver related to android and then reinstalled after a restart and that did the trick. For some reason android phones are giving me a lot of driver issues on windows 8.1
follow these steps here but make sure you read a chunk of the thread as the steps in the main post are not complete
http://forum.xda-developers.com/showthread.php?t=2432476
So, I rooted my coworkers Sprint G2 or LG LS980 using IoRoot a month ago and had TWRP installed on it. prior to doing this I had looked into what it would take to revert it to factory unrooted unmolested state. didnt seem to hard with the lgFlash tool and what not....
Well two days ago he accepted and tried to install the new OTA. he was on ZVA firmware, and I believe the new OTA was for 4.4... well the install of the OTA failed im pretty sure do to TWRP being installed instead of stock recovery. instead of stopping there and calling me he tried to fix it himself... I believe one of the things he did was to wipe the device. as in advanced wipe, select EVERYTING including system....
He gave it to me today rather pissed and asked me to fix it.
Ok, I have bee through MANY threads about reverting back to stock, and it seems I am having a serious driver issue... In my laptops device manager I can see the LS980, but it has no driver installed. I have downloaded many different versions of the LG drivers from various tutorials here and on other websites. I even tried to find them on LG.com, but no luck there.
I can get it into download mode, holding vol+ and plug in USB, but once I try to connect to it via LGMobile Support tool or LGFlash tool, they do not detect it. it tries to load three different modems, and the center one always fails. is there anyplace I can get JUST the driver, not the entire self extracting EXE files?
I was just going to copy a ROM onto the internal storage, but even using the mount tab in TWRP it will not connect to my computer.
PLease for the love of all that is sacred to XDA help me!!! I sadly do not know much about ADB... I have never really used it. at this time it is not installed and I wouldnt know what to install and how to ADB Push a rom onto the phone...
Edit, here is ONE of the tutorials I tried, but since I cannot get the proper drivers installed this hangs when I click the yellow arrow to start it....

okay so have you tried the following from this thread-
If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.

Yea, I have been trying that method... my issue now seems to be that one of the drivers is not installing correctly. So I cannot change the device to port 41. And the app will not see my phone. When I get off work tonight and can use my laptop again I will try downloading advanced and setting that up and see if I can make it work that way. I also read the other thread that was linked last night looking for the two terminal commands to try, both the fota, and the miscellaneous command... found the commands, typed them in, and now my phone boots to the LG logo and my notification light starts scrolling through different colors. I can still get to both recovery and download mode though, so I am not giving up.
Also in that thread someone mentioned koush's generic adb drivers... I downloaded those and will try that as well.
Basically if I can just get my darn laptop to connect to this phone I think I might still have a shot at reviving it.
Multi color led makes me think, wing kernel. Like installing zvc kernel over zva system modem.
You may have to uninstall all lg drivers, and reinstall
Sent from my Nexus 7 using Tapatalk
Well it was running fine until he tapped accept on the ota so I dont know how he would have gotten the wrong kernel.... I have uninstalled the drivers a few times and reinstalled different versions. There is always one that fails when I plug in the phone. Plus I get a message on the device about mediadata unknown, or not found.... something like that. I know before he called me he tried the wipe option in twrp. I know on my galaxy s4 we were not to use the wipe data command in there, I'm thinking he did...
But I can still get to download mode so if I can get my laptop to recognise it I have faith I can lgflash tool it back to life... if I can get the drivers to cooperate...
Quick update on this... I found a tutorial on using adb and managed to sideload a rom, derp milestone 1 I believe it was, and after it completed the phone booted up just fine. My friend wanted it to be reverted back to its stock unrooted state, so I tried LG mobile something or other on my laptop... you all know, the one where you hit options then upgrade recovery and it should download and flash stick software? Well it saw the phone, and said there was no upgradeable software on it... mind you the phone still has a working twrp 2.6.3.3 on it... I don't know... I tried LG flash tool, but i can't get it to be port 41 for that to work... but at least the phone boots and runs fine now.
Still having my driver issue though. When I plug in the phone windows installs 3 drivers. One is CDC driver which always fails. No clue why.
Any ideas?
Hey guys, it's 4am where I live and I'm becoming desperate now... Hope someone find a solution for my problem and is willing to help me.
I was using the latest CM12 nightly on my new d805 and decided to try the new CloudyG2 3.1. I was told the easiest way to do this is flashing a Lollipop bootstack (which I found here https://github.com/lg-devs/bootstack...master/d802/lp) followed by the Cloudy ROM itself.
I did it through TWRP, and then things started to cramble. On reboot the LG logo briefly appeared followed by a black screen. I've found this topic http://forum.xda-developers.com/show....php?t=2432476, downloaded the appropriated .kdz but my device isn't recognized by my PC. I've tried reinstalling the drivers and using the universal ones, but my computer just doesn't care about the phone being connected or not.
I tried to start sideload on TWRP so I could push a CM12 .zip back to the phone, but the sideload doesn't start, so I essentially can't send any file to the phone. Is there any hope for me? I'd be so happy if someone gave me a solution for this... I really can't afford to buy another phone right now and this is my only method of contact with some relatives.
Huge thanks in advance, this community rocks.

Bricked LG G2 D802, some advice ?
Hello guyz,
Unfortunately during a software update the phone just got cold with black screen.
I started searching and found a solution: http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
I used all info as instructed and managed to manually flash the partitions like in this thread: http://forum.xda-developers.com/showthread.php?t=2582142
But unfortunately i got stuck after the last step (ubuntu flash), the next thread does not help me with my "softwareless" phone.
Any advice how should i proceed in order to push the cyanogen 12.1 and gappa to the get the phone up and running ?
I currently have TWRP but a lot of features are not working, i guess it's as expected since it was hard wiped.
Thank you !

Well, if only i could somehow transfer the cyanogen and gapps to the device i could install the software via twrp
But i don;t how to do that, the PC sees the phone as "!G2"
I installed ADB and tried to see if it recognizes the phone but no luck, figured out maybe i can push the firmware via adb

As this forum is not for you alone it would be nice to share your way to a fix. Others might get into the same issue.
The problem was the images them self's. I tried the SRK Tool images to flash under ubuntu and managed to boot in recovery and flash a EUR 10B via download mode.
Just replace the images that are suggested in this thread http://forum.xda-developers.com/showthread.php?t=2582142 with the ones from the SRK TOOL and have a EUR 10B firmware ready to flash
