I have a Verizon LG G2 VS980. The phone was rooted and running stock firmware.
I hit the "Update software" by mistake on a business trip and when the screen went black, I powered off the device in hopes of preventing the update (which I see now was a HUGE mistake.) Now, the phone only boots into fastboot mode. When I try to hold the vol + and power, it takes me straight into fastboot as well as the vol - and power.
I have tried to do the factory reset by holding vol - and power and then pressing it again when the LG splash screen shows. When I select to hard reset the phone, it goes into fastboot mode.
Now, when I plug the device into the computer, the computer will not recognize it. I am using the manufacturer's data cable, I have tried multiple USB ports, I have uninstalled and reinstalled the drivers countless times. Neither fastboot or ADB in command prompt recognize the device. However, the device does show that there is an android device plugged into the computer.
I have spent hours looking through every thread that addresses issues similar to this but I have not found a solution yet. What can I do from here?
First of all this belongs in Q&A not development.
Are you doing the hard key combo correctly? Power the phone down, when when it reboots is vibrates. When it vibrates you hold power and volume down. At the splash screen, you release it then hold them again.
Did you try this thread?

When you held power up and volume on reboot, did you have it connected to the PC to see if you had download mode?

-check your device manager and see if your computer recognizes it.
-Try another computer.
-Another USB cable
Your computer should recognize it since you had it recognize it before.
Yes, I have tried multiple usb cables and have tried to get into download mode both plugged into the pc and unplugged.
Am I correct in assuming that step one needs to be to find out how to get the computer to recognize the device?

I have a Motorola Droid 4. I installed SafeStrap recently on it and installed CM11 to the stock rom (mistake I know). I kept running into issues and I finally sorted all of them out and I decided I wanted to restore back to stock and then install CM11 to a rom slot. I come to find out that I am unable to restore my stock backup as it keeps failing. So I then decide I am going to just go ahead and restore my CM11 backup to rom slot 1 and make it the active boot rom, but that turned out to fail to for whatever reason. I reboot my phone several times and received the Motorola logo followed by the dreaded Android on his back with his chest opened up and the exclamation point/triangle coming out of it.
So I gave in and decided to just go ahead and use the Droid Razr Utility that I have used before to reinstall the stock ROM and start all over. During this process everything seems to be going fine. I am able to boot into Fastboot, the PC recognized the phone and can see it. I then start the recovery by doing option "2" to wipe and install. My phone reboots a couple of times and then comes to the point of another reboot but the phone never turned back on. I've tried many button combinations to get this to boot up but nothing seems to respond. I have attached a screenshot of what the Droid Razr Utility showed when the phone was attempting to restart but never did.
I purchased a Fastboot cable to hopefully get me to the point of my PC recognizing the phone but that does not seem to work. When I plug in my phone Windows never detects anything. I removed all the drivers and nothing. If I plug the phone into a charger the Green light flashes for a split second. If I plug my phone into the computer the Green LED light will stay solid. According to Motorola this indicates that the battery is fully charged. I've tried reseating the battery to no avail.
So based on the information above and the attached screenshot, is my Droid 4 bricked and unusable now?
After doing a bunch of research I think I indeed bricked my phone. Since the ROM I tried flashing to my phone was not for the Droid 4 but rather the Droid RAZR, it looks like my phone is dead. I was hopeful and assumed that this would be able to be reversed by hooking up to a PC but apparently that is not the case. Perhaps I tripped the eFuse or something which is causing the boot loader to not initiate. I guess I need to get a new phone now unless someone has a nifty trick up their sleeve to get the phone accessible via a computer.
You are going to need a Team Black Hat cable, aka fastboot cable. Then plug it in, and run RSD Lite using the DROID 4's fastboot files. You can find the fastboot files at this website below. Download the one that matches the version of Android you have.

Ordered a factory cable on eBay; we shall see; thanks for the information
Even though my computer does not seem to recognize my phone when I plug it in. For example, I plug it in using the Fastboot cable and I never heard a sound from my computer like it knows something was just plugged in?
I did buy a fastboot cable from bluvector on amazon but that didn't seem to do anything for me. My Droid 4 still has a black screen and plays dead:crying:

Are you having the same problem as me? Your Droid 4 will not turn on and just sits at a black screen when you push the power button?
@sd_shadow you out there? I would love to hear your advice on my issue to see if there is any hope for my phone.
I received a FastBoot Cable but when I plug it in nothing happens. I also have a Kindle Fire HD and plugged the fastboot cable into it and powerd it down and back on and it boots normally. I'm wondering if the fastboot cable is faulty? Also I think my droid 4 may be completely shot since pushing the power button does nothing for me so I don't know how I could get back into Fastboot mode, unless a confirmed working fastboot cable will force the phone to boot and enter fastboot mode?

Motorola Devices will be powered by the Fastboot/Factory cable, when you connect the Droid 4 to pc via a fastboot cable, it should power on but you may need to select fastboot mode in bootmenu options.
Not sure about the kindle HD, but an Original Kindle Fire 1st gen, will boot direct to fastboot mode, when connected to a Fastboot cable
Both require Hardware cable and device to be working correctly.

According to the description on the amazon site that I bought this cable from it shows the cable as being able to support Kindle Fire HD, that is why I am thinking that this cable is faulty, since it is not working on my droid nor is it working on my Kindle Fire.
I am thinking on buying a different one and returning my current one but i'm hesitant to do so. I have my doubts that this will allow my Droid 4 to boot up and/or be recognized by my computer. Since I get no response with the Vol-, Vol+, Power button combinations i'm thinking this is hard bricked because of the wrong files I flashed to it.
Before I made this mistake the phone was at least responsive showing the android/exclamation point screen. Then my dumbass ran the wrong flashing utility and that was all she wrote.
Do you think there is hope for my my phone even though the power button yields no response? If the fastboot cable will at least allow my phone to be recognized by my computer then I think i could save it, but that is where i have my doubts, but would love to try.

If you flashed Droid Razr firmware, yes it's bricked. or haven't seen anyone recovery from that yet.
@bean1975, did you have any luck with getting the fastboot cable to recover your phone?
Hello guys I think I have bricked my device. I had successfully installed CM 12.1 but couldn't install google play store. It was firmware 5.1.1. So I decided to install os original firmware v5.1.1 using Rootjunky videos. How to Firmware Restore or Unbrick your Amazon Fire 5th gen Tablet. I successfully loaded the firmware ( Install from the ADB complete )but in the end I screwed up. I didn't remove the cable before pressing reboot system now(in recovery mode). Now tablet won't boot up. Now connected to pc some software installs and I hear disconnecting/reconnecting tone, few seconds interval. In device manager ,other devices it shows MT65xx Preloader with yellow icon. Please help if there is any hope. Many Thanks.

I can't even boot it up. I tried pressing low volume + power button / all kinda combinations. When connect to pc it keeps disconnecting and reconnecting in 3-4 sec gap. There is no fire/device in device manager. Installed all softwares . Before bricked device everything worked fine. I can't reach to recovery option. All these solution works after that process.
At 7:35 on this video of Rootjunky - { How to Firmware Restore or Unbrick your Amazon Fire 5th gen Tablet} I was supposed to plug out the cable and press reboot button. I didn't remove the cable just pressed the button and from there device don't start. I don't see any logo ,the screen is just switched off. The only movement I see when I plug it to the pc. The reconnect/Disconnect tone from pc I think it's in Loop. I hope you guys understand now how exactly I bricked it. Previously I installed the CM 12.1 successfully and it was smooth and fast.
Before this solution, on other devices I had MT65XX PRELOADER option with yellow icon. It stays for a few sec then disappears and this process repeat itself.. After updated drivers ( disabling driver signature on windows 10) now there is no fire device in device manager but connect /disconnect tone is there.

I don't know how to flash firmware through sp-flash tool. . I will give my best ,every solution you tell me. I got this tablet as a gift and I gave it to my younger brother. He gave me to install some games except I installed custom roms / tons of softwares but games on it and finally bricked it. Thanks guys for help.
any updates?
Help please, same issue, same mistake! Device will be "connected" (windows sound) and disconnected, and continue, it won't stay connected, (battery disconected, tried holding volume key too) therefore I cannot use flash tool

Device is unrecoverable if it can not boot into stock recovery mode by pressing two outside buttons from a cold start.
Same issue here. Any work around
Unfortunately I seem to have made the same mistake... Isn't it possible to buy a "Factory Fastboot Cable" and get it back to life that way?
Same problem here... instead of wiping cache and rebooting I pressed "Shut down" and it wont turn on again... it doesn't even activate screen. Nothing at all. How can it be recovered? There must be a solution out there!
My 1020 got bricked while flashing through WPInternals.
In the middle of the flashing the USB got disconnected and after that I have blank screen. The power button pressing does make phone vibrate. Also soft reset combination makes vibration. However I am not getting anything on my laptop on USB connection. No connection notification. Nothing on device manager. I tried combinations to get it detected but nothing works.
So the question is, Is there any way I can blindly send force flashing to one of the USB port and make it happen ?
JTAG is the only option ?
same me hichic
Flash Mode
Hello,
try this: power off/reset and power on holding vol-up key. You should get a flash-and-cogwheel sign on your display. If so, you cna reflash your (valid) .ffu file using PhoneImageDesigner/Lumia Flash Tools (->google!).
Are you sure your USB cable or port is not broken?
Best whishes,
Joachim

Okay, I have already tried that, since the USB got disconnected during boot loader flash, it does not display anything on the screen when I start with power button or reset combo. It only vibrates.

I have changed the cable too(USB flex cable of my lumia and USB cable too), It does charge battery, does keep flashing the start button once in a while when the cable is connected. I am sure USB is working fine. But not getting detected in PC.

Hello there... Any solution you found? I am stuck with my zuk z2 in same situation ?? any help ?
I have a similar problem.
What caused the black screen? -
History:
I booted to test mode at 2.5.033 ST, the phone got stucked at this menue there was no way to get out. TWRP Restore to Nandroid bougt only black screen after 2nd vibration and ZUK logo.
I fixed the Test mode bug, by flashing the ZUI 1.9.104 ST Stock ROM via QPST.
After the phone was "repaired" I unlocked the bootloader, installed TWRP, made a nandroid backup of fully stock ROM and restored a nandroid backup from before the test mode problem.
The nandroid restore was successful, I rebooted the phone and it was "dead". Black screen, only rebooting (perioldy vibrating) there was no end, until the battery was empty.
I got no luck to reach any mode with tricky button pressing (vol+ pwr; vol- pwr; vol+ vol- pwr; usb in vol-) nor Windows detecting the phone. That's why I decided to remove the back glass cover, to got access to the battery.
Now I'm able to get the phone detected by my PC.
What I did: disconnect the battery, connect the phone to my computer, pressed the vol- button and connect the battery.
This made my PC able to detect the phone, but no I have an other problem. Windows only detects the phone as "unknown usb device (device descriptor request failed)". I don't know any way to install the driver....
Maybe anyone is able to help me or has any tip?
Thanks!

What id shown in unknown device.
Like ven_9102&dev_1234
Maybe with editing quallcom drivers for your device id, you can still install it.
and if luck qpst can recognize it as qualcomm debug mod

Alright bro, there is one method you can try.
http://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
I assume your phone is a brick now. The only method you can use is the 9008 unbrick mode. (AKA QBST)
There are a few things you need to prepare before you save ur phone. U need to download the require application that the website provided above, after you set everything up,
make sure you download the latest 2.5 QBST rom,
http://bbs.lenovomobile.cn/z2pro/t554654/
Because ur phone wont be able to enter 9008 through software, thus u need to do the following.
1. Load the content XML fille,
2.Turn off your phone. After it's fully shutdown
3. press and hold the volume up button for 3 seconds
4. press power button while hold the volume up (press it for 0.5second and keep holding it)
5. after 0.5 seconds, plug in the usb right away
6. the QFIL tool should appear the Qualcomm usb QD loader
7. the download button should turn blue
8. flash it and wait for reboot

Thanks for your tip.
I followed your described procedure, but the phone will not be recocnized by the PC.
1st: I loaded QFIL XML file. (By the way this tut is made by me)
2nd: I disconnected the battery (The phone can't be turned off normally!)

Yes, I did exactly you described. Sorry but this isn't working.
I don't know what I should do. Even a repair shop couldn't fix it.
Maybe I need to do this:

But I don't want to destroy my PC (3000 bugs)

I will report the result.
OK. I made the deepflash cable.
After using it there is no difference between pressing one of the button combinations I recently mentioned (VOL+ or VOL- or PWR).
The phone will be detected as Unknown device. After intalling my modified driver to match the unknown ID, QFIL don't detect the COM Port.
Hello had the same problem, only with the difference that my battery was not completely discharged.
What has helped:
1 Start QFIL Tool
2 Press the volume +
3 Connect the original cable to the PC
4 QFIL Tool recognized the phone and I could play an original Rome.

Ps. Is now the battery cover (glass) broken?
No, I used a hairdryer, a razorblade, plastic tool and a suction cup to lift the backcover glass.
The glass is fully intact no damages.
You have good nerves. I would not have expected that.
But in the end, it does not matter if it does not start anymore.
Thank you again for your great instructions for playing and rooting the mobile phone.
I hope you get your phone back.

Good and bad news
The guy unbricked the phone successfully, I received it today.
Now I have an other problem:
The phone is very very slow and laggy now.
The problem occurs everywere, Recovery, boot (the bootlogo laggs), booted System, also the test mode laggs now
Furthermore the sceen flickers sometimes and at the right side the sceen is mirrored sometimes.
Did anyone has an idea?
What I did today:
reflash through qfil

Hi m_atze, I am exactly in the same situation as You. After using deep flash cable method, I got "unknown usb device (device descriptor request failed)". Could You tell me what was the solution to unbrick the phone?
