Urgent!Mobile is fastboot mode

I have an LG Optimus one p500 that's stuck in fastboot mode.
After doing factory reset,phone entered in fastboot mode. After selecting that the phone rebooted but was stuck in Fastboot mode. It's been stuck for 5 days and I can't figure out how to exit fastboot or just reboot regularly.
Methods tried:
-Battery pull then turn on
-Press and Hold Homekey, Powerkey and Volume down when booting
-Run fastboot on my command prompt and reboot, continue or flash command
-Phone is not entering emergency mode
<But they all end in fsatboot mode "Fastboot: Processing Commands" still>
I've tried everything and read everyforum, My questions
1)How can I just reboot my phone regularily! so it's not in fastboot mode?
2) Is there a command prompt for fastboot that willl exit fastboot?
I just want my phone to work normally! Please help, much appreciated!
Please reply fast because my phone's warranty is over.

Now this is spamming.
I've already posted a solution on this thread.

[Q] Stuck on fastboot with broken pwr button

Hi I have the following problem: after I flash Cannibal open touch recovery I could not flash any .zip file so I decided that I go back to CWM touch so I restarted my phone. Phone booted into fastboot mode with the following message no boot or recovery IMG so I decided to flash recovery with fastboot. I opened the folder with fastboot command flash_recovery connect the phone to usb but the command line always showed waiting for device. I unplugged the phone and tried to press the volume keys but nothing happened as if it freezes. I pulled the battery and try it again but no response. I cant connect phone to odin because it has broken power button and after I insert the battery it always turn on itself. Please advise me what to do thank you.

Seems your drivers have gone corrupt. Try a different system and use Nexus Root Toolkit.

I tried this option but without success. Phone does not respond to anything. No volume up or volume down. It´s just stucked on bootloader.

This link says that if you get <waiting for device> , then fastboot is not configured properly. Check out the link over here.
You may also try this command "fastboot boot recovery-clockwork-6.0.4.3-crespo.img" to boot into recovery without installing it.

no hope

The reason you cannot navigate in fastboot/bootloader is that your powerswitch is probably stuck in the "on position"...does your device immediately power on when battery is inserted?
The way i solved this a few months ago was to completly remove my powerswitch from the board power my device on..use quickboot to enter fastboot menu and input commands...
Also completely removing your power button makes powering on your nexus alot more complicated.
what i did was go to download mode (holding vol+ and -) and pluging phone in..this takes you to download mode
then you need to get a copy of a boatloader file to flash via odin which will reset your phone and power it on...pm me if interested i can provide you with files necessary

[Completed] Bricked zenfone 2 - OTA update while rooted - unsucessful flash

My problem:
I had a temporary CWM installed on my Asus Zenfone 2 ZE551ML 4gb/32GB and without thinking, installed an OTA update form 2.20.40.63 to 2.20.40.90.
My phone booted to the Asus logo with the loading circle and got no further.
Sadly I did not have USB debugging enabled at the time so I cant detect it in ADB in recovery mode to sideload.
I have tried to copy firmware to my Micro sd and load from there but my phone has never recognised or mounted SD cards so that is out of the question.
As a last resort I tried flashing the Boot.img, Recovery.img, droidboot.img and system.img, now it wont even get to the asus logo without coming up with and android logo with a red triangle above it, the same logo that comes up when I now try to enter recovery mode.
I have recorded a video of the process I followed to flash the zfone, but cant post it here as this is my first post, but I think I can send it to someone through messages
What am I doing wrong and how do I get my phone back?
Any help would be hugely appreciated, and keep in mind Im a bit of a noob so set by step instructions would be awesome, Thanks guys
Update: the original .img files i used were apparently already rooted, so I am now extracting the 2.20.40.90 firmware from the official Asus site and I will try to flash with those.
but I cant find the system.img inside the UL-Z00A-WW-2.20.40.90-user.zip and was wondering, do I need to take out the Boot.img. droidboot.img and recovery.img then turn all the existing files into a system.img?

Hi, thank you for using XDA Assist. Try asking in your device's specific forum here, http://forum.xda-developers.com/zenfone2 They are the experts on your device. I would start by posting in this thread, http://forum.xda-developers.com/zenfone2/help/help-post-questions-instead-making-t2997779

Ahh thank you, sorry I didnt really know where to post the question

Fixed my phone!!
Ok guys, so I figured out what I was doing wrong.
I preformed the flash correctly with pre-rooted system.img, but I didnt wipe the cache, as soon as I did, my phone booted to a normal rooted device!!
If you want to do this yourself, download pre rooted versins of these files (easy to find with a quick google search)
Recovery.img
Boot.img
Droidboot.img
System.img
ADB tethered launcher (not needed if your phone can enter recovery mode)
and place them all in a new folder (lets call it zenUnbrick)
Boot your zenfone 2 into fast boot mode, then connect it to your pc
(Hold volume up button and power button, when your phone vibrates let go of the power button and continue to hold the volume + button until you see the fastboot screen)
Now hold down shift + right click inside the zenunbrick folder and select 'open command window here'
When that opens, run these commands in this order. Wait till each one finishes and be aware that the (fastboot flash system system.img) command takes quite a while to work its magic, so be patient and dont turn off your phone
fastboot flash fastboot droidboot.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot
when your phone reboots, it will most likely still seem bricked, but do not despair!! this is where you open up the ADB tethered launcher, although if your phone can enter recovery mode then you dont need this program
Option 1 - If your phone can enter recovery mode
Boot your phone into fastboot mode
use volume up and down to select recovery mode and use power button to select
wait for your phone to reboot
when you see the broken android symbol, press volume up button and power button simultaneously
select wipe cache and wait (it takes a while)
select reboot now
Your phone is now unbricked and rooted!!
Option 2 - If your phone cant enter recovery mode
Boot your phone into fastboot mode and connect it to your pc
open ADB tethered launcher
type 'ACCEPT'
when it loads type 'T4'
wait for your phone to reboot
select wipe cache and wait (it takes a while)
Select reboot now
Your phone is now unbricked and rooted!!

[GUIDE] How to Unlock Bootloader and Install TWRP

First, you’ll need ADB and fastboot, which can be downloaded here. To set up ADB, go to Settings/About Phone/Software Info and tap on build number until you get a toast notification saying “You are now a developer!” You will now have a new category in Settings called Developer Options. Go into developer options and enable USB debugging and OEM Unlock. You won't be able to turn it on if your phone is plugged in to your PC. Once you've turned it on, go to your PC, open Terminal or Command Prompt and type “adb devices”. Then plug in your phone and hit enter. You'll get a prompt on your phone to “Allow connection​s to this PC?”. Check Always allow and Allow. Now run “adb devices” again. Your device should now appear in Terminal.
If you have a SD card, download the latest zips from here and here onto your​ SD card. It'll save you a step later on.
Then you'll need to reboot to fastboot by holding down VOL- and plugging in USB while power is off. Alternatively​, you can type “adb reboot bootloader” in Terminal or Command Prompt.
Next, you'll need to unlock the bootloader. Bootloader unlocking​ will factory reset your phone! Once you're in fastboot, run “fastboot oem unlock” in Terminal or Command Prompt. Now the bootloader is unlocked.
Now it's time to flash TWRP, a custom recovery for Android. It's going to be the way you install custom ROMs and add-ons. Download Official TWRP here. Once you've extracted​ the recovery.zip, run this command: “fastboot flash recovery path/to/recovery.img”. Once the file has flashed, disconnect the USB cable and battery. The next step is important! You're going to need to boot into TWRP for the first time. With the phone off, hold down VOL- and press power until the phone vibrates and the LG logo appears. While still holding down VOL-, release and immediately press and hold power. You should now be at a white screen that says “Reset all data and restore to factory settings?” Use the volume and power keys to select yes and yes again. If you've installed​ TWRP successfully​, it won't actually factory reset your phone. Now you should see the TWRP screen. If you don't see the TWRP screen and instead see a floating ring that says “Erasing”, don't worry. Let if complete and try flashing TWRP in fastboot again.
In TWRP, you'll be greeted by a screen that says “Swipe to allow modifications?” Swipe it, then go to the Wipe tab. Go to Wipe, then Format Data, then type yes, then go to the Reboot tab and select Recovery to reboot into TWRP again. If you're prompted to install the TWRP app, don't bother.
Once you've rebooted into TWRP again, it's time to disable encryption​ and root the phone. Download the latest zips here and here. Skip downloading them if you already put them on your SD card earlier. On your PC, push the files to your phone using the command “adb push path/to/file.zip /sdcard/”. You can drag and drop the file into Terminal or Command Prompt to copy file path. Then go to the Install tab in TWRP and select the no-verity-opt-encrypt.zip, tap Add more zips, then add the root zip, then swipe to flash. Let the zips flash, then tap the Reboot System button when it's done. Your phone will take a little longer to boot and might reboot a couple times.
Once you're back in the OS, go through the setup wizard. Set up Magisk. If you stay on stock, you should install an app like Quick Reboot Pro from the Play Store to make it easier to reboot into recovery. Now reboot back into TWRP and go to the Backup tab. If you have a SD card, set it as the backup location. You can enable compression if you want. This will make a full system backup that you can restore from as long as you have TWRP. If the backup takes up too much space, you can put it in Google Drive or your PC later on.
You are now ready to install ROMs!

Please explain more in detail so you can be helped better In what ways? What are you doing to get into bootloader mode? I've never had any issues on my T-Mobile Stylo 2 plus. Are you trying to get into bootloader using buttons manually or through twrp or adb?

You hold volume DOWN and power then soon as screen comes on and you see LG you let go of the power button and then immediately press power again and you never let off volume DOWN. That doesn't work?

Ill try that i think i wasnt doing it correctly i was holding down power button then i let go an i was holding down the down button. Ty for u help ill try it later today.

Hey there, I've got the LG K530F, is there any chance of unlocking it? I looked up the LG developer website and it's not listed in there, filling that form will just lead to a popup regarding that. I thought about downgrading it back to MM (Android 6.0) using the K350F10d_00_02221.kdz firmware package aiming to be able to run fastboot oem unlock, but I'm afraid of getting it bricked. Anyone tried it? I recall doing something like that to unlock the LG Optimus L9, but that one was way older and had much weaker security measurements.

Can't get into Bootloader
Hi i have a LGL82VL and when trying to use adb reboot bootloader it just restarts, And when using Vol Down and Power it just comes to the factory reset page (Hard Reset)
Any ideas on how to get to the bootloader? i checked with fastboot devices while on the hard reset page and got nothing. Any Ideas?

Phone stuck at fastboot mode

Hello, everyone I have an Ulefone note 8 dual sim which after some time of use suddenly showed up dm-verity corruption at start up. I searched through google and decided to flash the rom again with sp flash t ools (Ulefone official rom)
So everything went smoothly, but after i started up the phone, it's stuck at fastboot mode. Here's a photo
The problem is, I can't exit fastboot I tried pressing just the power button and power button and volume up/down and the result is the same.
Can anyone help me?

bro you can exit fastboot from your pc by cmd "fastboot reboot"
or click all button for 30-60 sec or remove battery plug
