I have an old LG G Vista (VS880PP) without root, stock firmware android 5. For no reason, when turned on, fastboot mode began to load.
At first, the phone booted normally time to time (if pull out and insert the battery back), but now it doesn’t want to boot at all. I can't even charge that phone because of this...
It enters to the recovery mode without a problem, but it does not boot into the safe mode (it did it before I made a hard reset...). Deleting the cache/hard reset did not help.
It does not go to Download mode either. When I hold Volume+ and connect it via USB to PC, the pre-boot mode is displayed only.
When connected to a PC holding Volume+ but without a battery, the question mark in the charging silhouette shows up and that's it...
Installed:
- adb,
- LG mobile drivers
- LG PC Suite.
- LG Flash tool 2014.
But I can not install "LG mobile support tool" because the installation process hangs at 5% indefinitely (the same situation on a laptop with win 8.1).

I have an LG E435g. I tried to flash another version of stock firmware (V20a_00) using KDZ updater tool. It did flash, but my phone is f***d. The screen is totally black (no logo,etc.). My PC recognizes that it is connected, but I cannot load MTP driver for file transfers. It was in debug mode during flash, but isn't now because I can't use adb. Have tried everything in forums, nothing changes. I will pay ANYONE to fix as I am at wits end and know just enough to screw s**t up. Totally unable to get into download mode, emergency mode,etc. Phone is not rooted and the bootloader is locked.
No problem

Hi,
I have installed inappropriate version of CWM on my L9. Now it won't boot at all. When I press and hold power button to start the device, it stucks in a loop like this:
1. Short vibration.
2. LG logo screen appears for a second.
3. Black screen for another 3 seconds.
1. Vibration occurs again...
2. LG logo... etc
Situation above describes a behavior of the phone, which is disconnected from any wires.
Now when I plug shutted down device into USB port to Windows 7 PC, following mess happens:
1.Computer beeps like, USB device is connected.
2.Phone vibrates shortly.
3.Phone shows LG logo for a sec.
4.Phone shows black screen for 3 seconds.
5.Computer beeps like USB is disconnected.
... and again, and again.
Adb nor fastboot doesn't recognize any device (it did, before I have installed that wrong version of CWM, so USB drivers are OK I guess).
I tried hard reset, LG update tools, LGMobile support tool and of course I spent a whole day by searching this forum for any solution. I found similiar cases to mine (continuous beeps like Windows is detecting plugging and unplugging USB device), but this seems to be quite different because of continuous restarting of the phone, so the PC doesn't have a time to initiate USB device.
I would be really greatful for any help. Thanks
Edit: Problem SOLVED!
I solved it by following:
1. Download omap4boot from http://forum.xda-developers.com/showthread.php?t=1971014
2. Install driver for continuously plugging/unplugging phone in windows device manager (use omap4boot-for_optimus-v1.21\usb_drv_windows folder for search driver). Install it while the device is connected to PC.
3. Run command line and navigate to the omap4boot-for_optimus-v1.21 folder and run start_fastboot.bat.
4. Disconnect phone from PC.
5. Select 3. item Prada (works for L9 P760).
6. When prompted, connect turned off phone to the PC.
7. When promted to fastboot devices, choose Yes. Device should be found now. At this point you have approximately 3 minutes (device should stop restarting itself for a while) to do the rest.
8. Run another command line (do not close current one), navigate to android platform-tools and run fastboot flash recovery command with appropriate CWM img file. File can be downloaded here http://mobotalks.com/android/how-to-unlock-the-bootloader-and-install-cwm-recovery-on-lg-optimus-l9-ultimate-guide/
Done.
Hi, I was looking everywhere since yesterday but can't find a solution. I had cwm + twpr + lollipop cm12. I've decided to back to stock, so as allways: driver, b2cApp, kdz, v20h and v10a, usb, s/w mode, xml parser, shhtp, etc... Standard offline kdz method. But during flashing I stuck on 15% and get the info that my phone anad pc are not connected by usb cable, I tried changing usb ports at pc, reinstaling everything, but I have still the same error. If that woldn't be much enough I ****ed something up and I think I don't have any recovery right now
I can put my phone in s/w mode but I stuck on 15% with usb not connected error.
I can put my phone in fastboot mode but my pc does not recognize it, its just pluging in and out it from windows.
I can put my phone in stuck on LG logo 'mode'
Any help? How to unbrick it? How to flash stock or at least some custom recovery? Of course unlocked bootloader. Please help me :crying:
Key it ****ed up even more.
When kdz show me to connect my cable i clicked retry, plugen cable out and in, kdz found my device, and go to step 2. In half way I had again the same error, so again clicked retry, plug out, plug in. Again founded my device, when I had downloaded 100%, same situation. founded my device, log that tool is extracting kdz and nothing. Waiting about ~1,5h, nothing happend, so I diconected cable. In that moment kdz go to third step and I get windows force close for not repodnig app kdz. I said a loud **** and started again. Phone has not been found anymore by kdz. After a few tries, booted to fastboot, and connected to computer. It has been found as Google Fasbtoo USB, no way to update driver to fastboot. I disconected phone and decided to try again with s/w but nope. S/W not turning on anymore (with or without battery). Fastboot not turning on any more. Just LG logo, when I'm connecting device to PC it is sometging pluging in and out but nothing showing in device manager
Any ideas? Please!

If you gotta Recovery access AND the latest and BUMPED recovery (for example TWRP), you can still try to flash THIS:
-download the ROM from the PC;
-then, install ADB on linux or windows;
- 'adb push path_to_TOM_on_your_PC (for example, on linux, '/home/user_name/Download') /sdcard/Download (folder where ROM will be pushed in your device);
-Then try to flash the ROM.
It seems weird that your device isn't recognize with Linux, but try this still..
@almars are you on stock? What caused your problem?
There is indeed a chance to save your phone. 99%chance
so before I had stock but now I do not think any system.
One day shut down with the message "the system will now be turned off" and began to restart. From that moment, the computer does not detect my phone. I started the recovery and performed Dalvik cache, date etc. I can start download mode but it is the lack of communication with the computer.
Now, after the power is turned LG logo already is and end, nothing happens
Hi casual_kikoo , unfortunately I can not use the ABD because the computer does not recognize the phone.
Drivers from LG and ADB, of course, installed

For me it does not work "Since the phone turned off, press power + vol down, release as soon as the logo appears and then hold vol down + vol up"
If nothing works you may have to open the phone to unbrick it and flash the right stock files to it. Also see general for several unbricking guides to see or you could still fix your phone without doing that.
1. The phone was connected to Powerbank and after disconnected can't turn on to stock rom.
2. When I click on I see only LG logo and after 5 minutes logo my cellphone provider.
3. I can turn on Factory reset but after I choose factory reset after next reboot still is bootloop.
4. I thought that I can turn on Download mode I hold volume up, plug in the cable, and I see text "Download mode" and it tells me to keep holding. after 1 min. nothing going on. I have seen on internet photos that download mode should look diffrent than mine.
5. When I'm in "download mode" after 2-3 min. it turns on fastboot.
6. I have installed LG Driver but my computer recognizes my phone as an USB charge only interface - Lg Flash Tool and LG PC Suite didn't see phone
Any suggestions ?

You can try installing google's driver and finding your device in adb, also check in device manager if your pc can even detect your phone
Unfortunately on my phone debug mode is turned off. I installed google drivers but Adb can't see my device.
My computer detect on my phone :
Modems: LGE AndroidNet Usb modem
Ports: LGE AndroidNet Usb serial port
Devices : Lge Android MTP Device
------------
Update
Finally I gave the phone so lg service and after few days They said that burned internal memory. Subject to close.
