A friend gave me their Sprint LG-LS970 claiming it won't boot. This is a non technical user that hasn't tried to manually update, root, or otherwise modify their phone.
It's booting to the recovery screen ("Android system recovery <3e>"). I have three four options reboot, apply update from ADB, wipe data, wipe cache, apply update from cache. I can scroll through the list with the volume buttons, but I can't select any of the options. I've tried pressing in both of the volume buttons at the same time, tried the power button, and also tried the three hardware keys that aren't illuminated at the bottom of the screen.
I tried to connect to my PC, but Windows isn't detecting a device. I've tried two USB cables and an 8 and 7 PC.
I downloaded the LG PC Tools Suite and attempted to do an "Upgrade Recovery" but it, like Windows can't detect the phone.
The only time I hear Windows detect new hardware is when I hold down the power button for while (like 30 seconds). If I keep holding down the power button I hear the Windows hardware sound go off over and over again. Once I let go of the power button and the LG logo comes up, I can't find anything in the device manager related to the phone or unknown.
I don't know what my next step should be. Perhaps I'm just really ignorant and don't understand what "enter button to select" means on the recovery screen.

I can't get my computer to recognize the device so that I can use adb sideload in twrp. There is no operating system on the phone so I can't install usb drivers. When I try, it says failed to install drivers. Can anyone help point me in the right direction. In the command prompt, when I type 'adb devices' nothing comes up. Any help much appreciated!
the phone is and Lg Optimus g pro e980.

Did you already solved it?
Right now my phone is bricked due to a failed attempt to flash an F240S KitKat ROM to my E980, but that's another story, at least I have access through adb.
This is what worked out for me with Windows 7:
1. Download and install LG's latest drivers on your PC: (http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425).
2. Unplug the USB cable from phone.
3. Press the power button until the phone turns off.
4. Immediately after power off, press the power and volume up buttons at the same time, the phone will turn on showing the LG logo, don't release the buttons. Keep both buttons pressed until the LG logo disappears.
5. Now that the screen is completely black, release the power button only, keeping the volume up button pressed.
6. Always with the volume up pressed, the LG logo will appear and disappear a couple of times, don't release the button.
7. When this cycle ends, the phone shows a box (in Korean in my case) that I guess is related to the service software (see picture).
8. You can release the volume up button and plug the phone to the PC with the USB cable, Windows 7 should install the proper drivers and you will have adb access.
That's it ...
doesnt work for me,boots meinto TWRP.
Try both volume up, volume down and power at the same time, this is the default combo. Using volume up and power button at the same time work sometime when the recovery doesn't work. Hold the buttons and plug in the cable should work. If that doesn't work for some reason, try the sabering but without the battery. Put the battery back in once the menu comes up.
The phone is in bootlopp (i think).When i turn on appears android on groundb with the red triangle and a chinese word.This disappears and appears again,for an infinite time.Display stays turned on.Turning on in bootloader it works,but just in bootloader.If i try to enter in "Restart bootloader,"recovery,"normal boot"ecc it's in bootloop again.So i can access only bootloader at the moment.I want to reflash system,droidboot imgs ecc with fastboot but...tried to recognize phone on an old HP Compaq nx6110 with usb 2.0 and win7.installed on it adb drivers,adb and fast-tools.don't think zenf2 drivers are important at the moment,now should consider just the adb drivers cause i can access only bootloader.however i think zenf2 drivers are installed on it.nothing.phone no recognized by fastboot and no recognized by windows.consider that on a xp and 2.0 usb pc (with fastboot,adb,and adb drivers on it) phone is recognized by windows as Android-Phone but then windows says i've not the drivers for the installation (appears the drivers' choosing window).No asus driver on it,on the win7 pc there are!!

When you see the dead android with red triangle, hold the power button and keep pressing it and quickly
press volume up button and release it but keep the power button and you will see the Recovery options.
Then choose "format Cache" with volume up & down button and enter with power button to format cache partition.
It would take a long time so don't be alarmed. When done, choose restart system and the boot loop should be fixed.
Good luck.

Didn't work for me ... if I keep pressed the power button for a long time, power off the phone and it doesn't entry in Recovery mode...
I resolved with "fastboot erase cache" command
It is normal to get that error when selecting 'recovery mode'
The next step is a little tricky. You have to press and hold the power button, then press the volume up button. It may take a few tries. Both buttons will have to be pressed together simultaneous to enter Android system recovery. Please also see http://www.asus.com/us/support/FAQ/1011956/

Hi,
I´m having a problem with mine. Can´t recognize phone in fastboot but it´s different. I already asked for help in general thread - all resources (page 47 to 50) but still can´t solve.
I rooted my device using method 3 (one click root) and first everything seems fine, but on my first reboot i entered on bootloader - recovery and started a wipe cache, but didn´t finished it, push power button and force it of (i seemeed stuck there - was wipping for more than 10 minutes). Since then i can´t solve anything, tried many ways to unbrick my phone but i seem the problem was i can´t connect fastboot. After a lot o tries, i entered in TWRP using method 2 and wipe, made a recovery, everything and as magic i can enter again on recovery, even tried adb sideload (it started, but when starts to write something - at 50% of the process just ended). So, long story short, i did a flash of the original firmware i downloaded from asus website using method 2 and now it´s working as original, but i still having the same problem (or maybe worst, since i can´t enter the TWRP recovery using method 2 anymore) and can´t root my device. When i tried to do anything using fastboot it´s just shows "FAILED", When i request adb devices shows a blank line. If my phone is on, using android, it shows the correct serial number.
I don´t know what´s happening, it seems to estabilsh a connection (when on its ok, method 2 freeze on teamwin logo - the tool can write something on phone) but can´t write anything. i´m worried because i think i won´t be able to do any update and i wanted a rooted phone to.
Anyone seems a solution?
I'm having the same problem today and I solved it just now! I can't even open the fastboot and recovery. Finally I install the software "shuame"(I'm Chinese, you guys may find other software) on my PC, and with it my computer read zenfone2, and I use the function in the software to open fastboot mode, then I flash the WW version recovery.img and boot.img with a one-click tool in zentalk(TW), then I just double wipe, the phone is alive now !

I don´t know any other software. Is this software only in chinese ? Can i try?
My phone is actually working, but i can´t flash anything, even MOFD_update.zip (the file it is used to make ota uptades)
is Your phone rooted? which method did you use? Now you can use fastboot normally?
My wife's phone is stuck on the AT&T screen when booting. I am able to get into download mode, but am unsure of what to do next. I've downloaded the PC Suite and Mobile Support Tool (which seems to be more recent) from LG but in both cases when I do the update recovery I can't get it to work. The phone is totally stock, no root or anything, and as far as I know had the latest updates.
Can anyone help me bring the phone back from the dead?
This would probably work=
Ensure the device is power off.
Note If screen is frozen, remove/reinsert battery.
Press and hold the Volume Down button then press and hold the Power button. When the System recovery screen is displayed, release both buttons.
Select Factory data reset.
Note Utilize the Volume buttons to highlight and the Power button to select.
Select Yes.
Note Allow several minutes for the factory data reset and reboot processes to complete.
I hope I didn't end up with the proverbial brick, but I think I did. I was trying to restore my D-850 G3 to a native CM12 state to give to a family member. I did a good job with it but got stuck on not being able to change some settings. So I decided to wipe the cache and do a fresh install of CM12. I got far too aggressive and ended up wiping out everything. I have no recovery file on internal or external storage that I can access, and it appears the entire operating system is gone. I can't boot into recovery. When I try Power+volume up, nothing happens. I just get the LG startup screen and it's locked there. TWRP was on the phone but now I don't know if it is or not. If I could get to a menu and flash TWRP then CM12, I'd be OK I think (I just did that on the OnePlus 3). But I don't know how to get into the bootloader. I can probably find another way to load files onto the microSD card if that's necessary.
I tried downloading and using various LG support tools but I can't even get it recognized on USB - no adb, no fastboot, no way to get to anything.
I'd love to be able to rescue this phone from death but it's looking bleak.
Is there any hope here?
Do you remember which software you used?
I tried it on my laptop and I know it works with other phones (that aren't bricked), but all the G3 does is charge.
I installed LGMovileDriver_WHQL_ver4.04 and nothing.
Also LG PC Suite and it doesn't see anything.
I'm on Windows 10 - I do have an old PC running Win7.
If I could just get the device recognized via USB, I think it's salvagable.
To enter twrp its "power" + "volume DOWN"

I wish that worked but only resulted in the LG splash screen staying on until I removed the battery.
