these are the possible reasons for that to happen
1) u dont hav the drivers for ur phone
download "pdaNet"(just search in google) install with ur phone connected.
2)if u r using USB 3.0 connect to USB 2.0
in my laptop i cant enter fastboot when i connect it to usb 3.0
samething happened to me too at first this fixed it.

Are you sure it says that your bootloader can be unlocked in service menu
7378423 in dialer i think
Sent from my Xperia ion using XDA Premium 4 mobile app
If some one can find me a way to unlock the bootloader on L28H i will be very glad...cuz i just bricked my phone and i`m flashing a rom for locked bootloaders
Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
Quote:
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the phone dial pad and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
After you have verified that you can unlock bootloader, scroll to the bottom of the page and click "Continue"
You will get "Are you sure prompt" accept it by clicking "yes i am sure" (i assume that you have read an understood it)
Then accept the "legal terms"
Finally you will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
You should now receive your unique unlock key, its displayed on screen, SAVE THIS KEY SAFELY
Extract fastboot_with_Android_USB_file.rar and open fastboot folder
Hold SHIFT and right click on the background of the folder
Select 'Open command window here'
Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which you received earlier.
Your device should now be bootloader unlocked

Is the same for any ION. Some can be unlocked, some can not be unlocked.

Yes i have the key from Sony but when i connect the phone to pc in fastboot my PC says that it could not recognize it and my phone then boots to the battery logo....EVEN THOUGH i have installed the DRIVERS via the flashtool (flashtool drivers)

then try to boot in fastboot mode via flash tool itself.
once device is in fast boot mode follow the instructions to unlock the boot loader. and It is not necessary to unlock bootloader to install custom rom. it is only required if you want to install custom kernel. recovery can be installed without unlocked boot loaer.
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 !

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?
Hello.
This could be more general question so I try to get an answer here. Device: H815 wit bootloader unlocked. USB debugging is enabled but PC is not authorized so I can not execute any ADB command.
My problem is simple, I have flashed the latest Genisys rom and after initial setup (included lockscreen pattern setup) I restarted the phone. No I am not able to unlock the phone with correct lockscreen pattern provided. When I "connect" three dots it says "Try again", when I connect four and more dots it stucks and I can not swipe another pattern.
I am also unable to enter into recovery/fastboot mode (with power+vol down buttons). The phone starts booting instead of boot into the fastboot mode.
Is there any way how to flash anything or delete files containing lockscreen pattern?
Thank you very much for any help.
Babi
EDIT: Solved with LGUP.
when you attempted to go into recovery by holding power + vol down, did you let go of the power button and hold again immediately (while keeping vol down hold) when LG logo showed up?
anyways, if you can get ADP to detect your device, you can use this command to remove lockscreens
rm /data/system/locksettings.db
rm /data/system/*.key
or if you able to get into TWRP, find that folder and delete those files manually.
sorry i'm at work and can't type long, but let us(community) know.
Yes I did. I tried it with volume down button released as well. So I am not able to enter into fastboot mode. This issues persists.
I know about these commands, but how can I execute these commands without authorized device (ADB litsts "unauthorized" device)?
No, I was also not able to enter into recovery mode.
hi everyone, today i tried to upgrade my g7 G710ULM whith LGUP but in the procees i got an error, now i have the phone stucked into a fastboot screen like that:

re flash correct stock KDZ file with newer LG up V1.15
Hold vol dwn and power till it shuts off then quickly plugin the usb cable from your pc and hold vol up while you plug it in and wait till download mode shows up.
My Lenovo P2 won't start. When I press the power button the Lenovo logo appears and after about 10 seconds it vibrates and the screen turns off and then on again and tries to start again.
i am using stock rom, oem is locked
1-) Recovery menu does not work, it just says "Boot mode recovery" above, but after 10 seconds it flickers and shuts down and tries to start normally.
2-) When I press the Volume Down and Power keys, I can enter the fastboot menus.
3-) Recovery menus do not work,
4-) I installed Rescue and Smart Assistant on the computer. and when I enter the Rescue menu and type IMEI, I get a "device not supported" error.
How can I solve this problem please help.
