Hello,
My H815 phone is stuck in fastboot mode.
Whenever i press the power key the phone goes directly into fastboot mode.
I wanted to reset the phone using the phone's menu but straight after that the phone booted directly in fastboot mode and it's now stucked.
I believe that the bottery should be dead as well.
The host has it's bootloader uncloked, however i cannot install TWRP as i receive a message command: unknow in ADB when i try to install the recoevery.
I tried different USB cables and different ports of the same |laptop, currently runnin windows 7 with all the drivers.
Looking for are feedback on how to install the recovery and get rid of the command:unknown error

Search for FWUL from Steadfasterx.

Which command are you using for installing TWRP in ADB?

so i had just htc dev unocked my one x, now i was using hasoons tool, and when i tried to flash a recovery in fastboot with commands, everything in the prompt said okay.. flashed successful and so on, and the bar on the top right hand side of my phone flickered as if to load, but didint. now when i go to recovery mode, it gives me the splash screen with some red letter **** about distrabution, then reboots. ive tried flashing every possible recovery for the one x, including stock, and seems to do nothing, help??
pic is the screen rite b4 reboot (thats what i get when i reboot into recovery)
EDIT:: now im stuck at the screen in the picture, will not boot into anything else, will not be recognized by adb. PLEASE HELP!!!!
EDIT EDIT: i can power off, and get back into fast boot with volume off, but im almost asuming i just have no recovery..... and it will NOT! boot into the phone no matter what, only booting into that screen... what the **** do i do lol this is kind of a panic now
Have you tried reflashing stock recovery? Also shouldn't you be in the AT&T One X forum unless of course you have the international version of the One X.
I have tried the stock recovery, but now its in fastboot and won't get recognized by adb on my pc as it did. It just boot loops now at that screen and won't get recognized. And this isn't at. &t

You're suppose to flash stock recovery in fastboot.
I know, I tried when it was getting recognized, now I can't even pick it up with adb
so its telling me to flash the stock RUU, but i cant use adb commands it wont recognize in fastboot, the computer dings when i plug it in, but adb devices comes up with nothing, i tried every usb port on my pc and everything

First of all ADB only works in RECOVERY mode not directly in bootloader. So do the following steps & instal custom rom (Any1 u like).
1. You need recovery.img in your fastboot directory
2. Go into bootloader and connect phone
3. Then use: "fastboot boot recovery.img" (thus booting your image from pc and not the installed recovery).
4. When in recovery, you can use the adb commands.
5. You can try with "adb devices" which should show you serial of phone.
6. command: adb push rom_rom.zip /sdcard
credits to broncogr for finding that adb works if you use fastboot boot command and to Jotha for helping me out!
I recently tried to flash back from Lego Rom to stock ZVC and have hit some trouble. I used CWM to clear the caches/data, as per usual, but after installing the ZVC rom the phone just boot loops at the Lego Rom boot screen.
Normally, I would jump into recovery, but my volume buttons no longer work (they failed after a screen replacement, I suspect the ribbon cable is damaged). What are my options? Can ADB force it into recovery for me?
I've installed the latest USB drivers, but ADB is not recognizing any devices (at the ROM booting screen or at the charging/battery graphic). Do I have any options beyond buying a new volume button ribbon cable?
I have the same issue in windows and ubuntu. Will LGNPST be able to communicate with the device?

well first of all yes you can reboot recovery using adb.
But if you installed the zvc rooted ROM then why is it booting Lego?
You can install philz or twrp for a full touch recovery and not need volume buttons. You'll still need to use cmd to do "adb reboot recovery" or adb reboot fastboot". You can also flash recovery from adb. Just get a recovery.IMG I think it's adb fastboot flash recovery.IMG or whatever the name of the recovery is.
But if ADB doesn't return any devices when I execute "ADB devices" how can I get it to send a reboot signal to the phone? When I tried "ADB reboot recovery" I was given an error about no device connected.

I must have not been thinking the whole picture. What can the phone do? What happens when you turn it on, do the volume buttons work at all? Because if you can get into recovery or fastboot at all then something can be done try multiple combinations as much as possible. I'm thinking hold the power button down and plug in USB. Wait for something to happen then let go of power. Does your computer ever recognize something is plugged in? Maybe during boot?
I think I bricked my G3 :/
I tried usual methods but couldn't get into recovery or download mode, then a few days ago I realized I could get it into this fastboot mode by holding volume up and plugging into USB as you would normally do to get into download mode but you have to hold up for a minute or so (it shows the download mode icon for a few seconds and then goes to fastboot) when in fastboot it connects to the computer and shows in device manager as "android device" and the phone says "processing commands" So I tried to follow this guide http://forum.xda-developers.com/showthread.php?t=2785089 to return it to stock, but I couldn't get it to show up in the LG software.
I read some forum posts about fastboot mode and found that by using the command "fastboot boot twrp.img" (the recovery image I downloaded) in command prompt it would send it to the phone and the phone would display some info and then reboot into TWRP, from here I tried to install a correct rom but the installation starts and there are some errors and then it hangs. I also tried the command "fastboot flash recovery twrp.img" but it fails. This is as far as I have got with it.
It came to me in this condition but the previous owner said he was running Cyanogen and it was working fine until he tried to update it with a nightly build. I suspect he might've tried to install the wrong rom for the phone or the rom was corrupt.
ou could try to revive the phone doing a testpoint and then use boarddiag tools (look in xda thread).
Here is how to make a testpoint: http://forum.xda-developers.com/showpost.php?p=65002893&postcount=17
Hello!
I'm trying to fix a LG G4 that goes straight into fastboot mode when it's powered up.
I've tried several things:
1. Holding power + volume down. It goes into recovery mode but when I click yes to restoring everything, it automatically takes me back to the same fastboot screen.
2. I've installed Android-SDK and updated drivers when I plugged in the phone. When I put in 'adb devices', there is nothing. When I put in 'fastboot devices', the serial number shows up. The bootloader is locked and when I put in 'adb reboot bootloader', it says 'error: no devices/emulators found'. Then I tried both 'fastboot oem unlock' and 'fastboot flashing unlock', it gives me: 'FAILED <command write failed <Unknown error>>.
3. I've downloaded TWRP but it obviously does not do anything right now with my errors.
I unplugged the phone from the computer and now it says 0% battery, it does not charge.
I'm really confused and lost at what to do. Any help would be appreciated.
Thank you in advance!

Hi! I did try to follow the guide to KDZ on here but I can't get into download mode. I'm literally stuck; the phone simply starts up right into fastboot mode.
I need to know the history. What model. What were you doing to get stuck in fastboot.

Hi! It's the H810 model. My dad was watching YouTube videos when his phone suddenly turned black and went into fastboot. The phone was originally from Wind Mobile but my brother unlocked it through the web. My dad uses ChatR. In order to start up the phone now, I have to plug it to a wall outlet before it starts up into fastboot. When I plug it into my computer directly, it says 0% battery but it does not charge up.
I know a fastboot usb cable force charges. But it sounds like a more sisnister problem if its like u say. Id sent it to lg for waranty on bootloop issue
LG-H810 Qualcomm 9008

Try to type into the terminal: 'fastboot continue'. This should make the system start up.

Just type "fasboot reboot" ..it should boot normally or just press power button for 10 seconds and release
my device came with unlocked bootloader, so I tried to flash twrp but every time i type "fastboot flash recovery C:\adb\twrp-3.2.1-3-whyred.img" and hit enter, the device seems to disconnect from pc and there is "press any key to reboot" in fastboot on my phone.
How can I solve this issue?`
Phone gets detected by adb/fastboot tool so its not a driver problem. I tried different cables and usb ports aswell.
Firmware is latest global stable.

Well if you already had adb in your pc, rename the twrp file to recovery, you don't have to move the twrp from download folder, open download folder press shift and right click then select open cmd here, on cmd type "adb device" to see if your device connected, then after that type this "fastboot flash recovery recovery.img" press enter than after that type "fastboot boot recovery.img" TEAMWIN logo should appear on your device and then you can unplug your device. Hope this useful
i am trying to flash twrp there is no folder called adb i have installed the 15 second adb and all so i have got this minimal adb flashboot and i tried with that and got this ---- FAILED (remote: Flashing is not allowed in Lock State). i have granted all usb and oem unlocking. please help with this
Phone shows unlocked during the boot?
I had the same Problem,after a Factory Reset works for me.
I am on Miglobe-Rom Miui10 8.6.28.
Minimal ADB is enough.
Or use this from Attachment.
Unpack with Win.zip and copy Twrp in this Folder.
Conect the Phone with your Pc ,boot into Bootloader and click "cmd-here.exe"
Use this Command
fastboot flash recovery twrp-3.2.1-3-whyred.img
@Nazukii - Quick question - any chance you could try running GameBench on your device, and see if our background service dies when the device is disconnected from the PC? I don't have a Note 5 Pro to test, and I've got some user complaints. Any assistance would be awesome!

If you have made sure that you have all the drivers installed and still have not solved, you need to use an Intel-based PC / notebook and use a usb 2.0.
