At first sorry for my bad english -_-
I have LG P670 v20i eur, i have unlocked bootloader and rooted. But, if i boot to bootloader mode when i want to flash recovery, my pc wont recognize the phone. And it doing a strange thing. Connects and disconnects and connects and disconnects....doing classic windows sound around. I hit the device manager and found unrecognized device and install fastboot drivers manualy, and it sasy that i have last drivers sinstalled but windows sill disconnecting my phone. I can do it in windows 8.1 and on win XP. Than i install cwm based recovery with lg recovery installer (for locked BL). Is there any possible way to install "artas182x" recovery without bootloader ? If i make flashable zip with "artas182x" recovery and flash with recovery for lock BL ?
Thanks for answer, for now i'm very sad :/
Edit: friend tell me that app "Flashify" can do this, and i have installed unofficial CM11 for now but, in bootloader my pc still doing same error

Dears,
I wonder if you can help
I did the following steps successful.
unlocking bootloader
rooting
flashing cwm recovery
flashing cm10 (updated to CM11 successfully)
flashing gapps
but the phone stays S-on.
Now my computers does not recognize the phone.
In the windows device manager is a one listed under other devices.
But when i am looking for drivers automatically or manually the drivers cannot be found.
When I reboot my phone into bootloader mode then my computer recognize the phone and i have access via ADB or fastboot.exe
fastboot.exe -devices is listening my phone as FA3AAW905529
Maybe I need to S-off my device, but i dont know how.
I would like to have acces to folders on my phone.
Alternatively I installed Airdroide as a workaround.
P.S. Drivers are installed
Sincerely
Alex
No idea?

Hello, Iam totaly f***ed up, I have Xperia P, rooted, unlocked bootloader, CWM recovery, with Cyanogenmod. Well at least last time CM worked, it was version for some tablet and I wanted to flash right ROM. But via CWM recovery it failed, so I connected phone to PC, launched "Minimal ADB and FASTBOOT" and flashed boot.img ( fastboot flash boot boot.img )from CM zip. It said it worked, but when I rebooted my phone, there was just red LED diode, and no light from screen or back/home buttons at all. When I wanted to flash stock firmware via "Flashtool", it said my devide drivers arent installed, but I installed them before from "drivers" folder in Flastool folder. So I downloaded some other drivers, but it f***ed up somehow, and now my computer cant install right drivers and when I connect my phone to PC in fastbootmode? (holding volume down when connecting USB), Iam stuck at Windows installing SOMC Flash Device, and it fails in couple of minutes. I really dont know what to do now. please help...
EDIT: ok my problem with SOMC Flash Device driver is solved... I just didnt hold volume down button long enough hope this will help someone too but still I have unusable phone and I need to instal stock firmware or something else that will help
Hello
I think I've bricked my P760. When i want to run my phone it stuck on LG logo and can't boot to OS. Everything was fine but after installing fix to camera i could boot to OS my phone once and after reboot i can't boot to OS anymore. My phone has root, unlocked bootloader, custom recovery and custom ROM. I don't have acces to recovery. I have only acces to bootloader mode with fastboot (VOL+ + HOME + POWER). Then i have a note "Welcome to LG Fastboot Mode ". My computer detects it and automatically installs drivers (Fastboot interface (Google USB ID). But the problem is that in Device Manager it all time blinks. It's connected and immediately dissconects. I'm using original USB cable from LG charger. When i'm trying to use cmd in fastboot & adb files it's waiting for device all the time.
I don't know what I should do next :C
Pls help guys

Go through this thread http://forum.xda-developers.com/showthread.php?t=2292828 it will definitely solve your problem, from the screen-shot it seems that you are using windows 10, i'm not sure that omap4430 drivers will work on windows 10 or not, but you'll try otherwise do the process on windows 7, your phone will revive...
@Codeplex its to complicated thread.
before mine become like this my phone alway succes writing recovery via adb fastboot but now i try writing recovery via adb fastboot always filed.
flashing firmware with cmahendra method always get 15% error..
I think all dev not care anymore about our phone..,
Hi!
I'm so stupid. I wanted to install cm12.1. So I rooted phone, unlocked BL. Then, I had first problem - when executing adb oem-unlock BL has unlocked and phone go to fastboot. But my comp couldn't recognize it (heard plugging in and out sound repeatedly). And here comes my "stupidity". I installed flashify and flashed CWM by it, got to CWM, installed cm12.1 zip. Of course wiped all data. Because I didn't flashed boot.img cm12.1 was freezing on fist setting up screen (nothing was working, just power button - pushing 10s turned off phone).
I wanted to flash boot.img by fastboot. But I still had problems with drivers(omap4boot didn't work). So I tried to recovery system by LG Mobile Support Tool. Everything got fine, but then phone stuck on the LG logo.
S/W Uprgade mode works of course, but I can't get to recovery now.
I'm using Windows 8.1
Any ideas?
Edit.
Ok, so I tried to install omap again. I did it, but the phone is still repeatedly conecting and disconnecting and in device manager I cought omap4430 driver whith waring mark for a while. Any ideas now?
Is it the non-animated LG logo?
This should work:

The download links for the firmware are probably not up to date. Use this to download: http://forum.xda-developers.com/showthread.php?t=2287573
If your phone still goes beyond the non-animated logo, there might be easier solutions.
It was after animation.
Anyway, I have finally solved this problem by installing new system using Bride's solution with full wipe.
Yesterday I tried to flash a a new rom on my Xperia Z2 (unlocked bootloader).
From TWRP I did an advanced wipe and selected basically everything except my mircoSD (because it has the new files).
After a long time of waiting I tried to flash the ZIP file and it gave me an error. I thought this had to do with the wipe so I decided to reboot my phone.
As you can imagine, it got stuck on the Sony logo (because system would be empty).
From this moment I couldn't do anything with my phone, except from the tool Emma.
I now have some clean installation of Sony their Android 6.0.1 for the Z2 (23.5.A.0.570) but Im unable to flash TWRP through fastboot.
The command adb devices shows my phone, fastboot devices gives an empty response.
When I restart to the bootloader from adb and try to flash TWRP I get the message "< waiting for device >".
I tried on three different PCs including a clean install of Windows with all kind of different drivers, yet I cant get fastboot to work.
Am I stuck with this unrooted version of Android now or do you guys have any suggestions for me?
Thanks in advance!
Install drivers correctly

As I said I've tried all kind of different drivers (Android tools, Sony drivers and flahstool drivers). So for me it's hard to tell what I'm doing wrong.
My computer notices the phone (if I hold volume up and attach the charger), it just doesn't show up under fastboot devices.

Okay, apparently it was because of the driver signature stuff in Windows 10.. The fastboot command now works fine!
Next problem occurred though, flashed the newest TWRP recovery but as soon as I enter "adb reboot recovery" my phone just normally boots again..
Why do things never work out the right way for me as they are intended..

Manually boot into recovery by booting up your device normally and when you see a violet LED, press vol+.
