HTC ONE M7_U/M7_UL - ADB PUSH & FLASH A ROM - DETAILED INSTRUCTIONS

Prerequisites:

• You need ADB and FASTBOOT on your computer, either by installing the Android SDK or Minimal ADB and FASTBOOT
• You need to know how to start a fastboot/adb command prompt:
  
  To open a command window prompt, in Windows go to Start Menu --> ''Run'' then type cmd. Change the directory to the ADB folder on your machine:
  

  • If using the default install location for the SDK:
    
    Code:

    cd C:\adt-bundle-windows-x86_64-20130219\sdk\platform-tools

  • If using the default install location of Minimal ADB and FASTBOOT:
    
    Code:

    cd C:\Program Files (x86)\Minimal ADB and Fastboot

  • Or hold left shift + right click a blank space inside the folder where adb and fastboot are located and select ''Open command window here'' from the contextual menu.
    
    
• You need TWRP recovery (2.6.3.3 or higher) on your device.
  
  
  

  1. Unlock bootloader if not already unlocked:
     
     
     Thanks to Electroz for the video tutorial
     
  2. Flash TWRP Recovery:
     
     1. Make sure the recovery.img file is in the same folder where adb and fastboot are located
     2. reboot phone in bootloader mode
     3. Flash the recovery:
        
        Code:

        fastboot flash recovery name_of_recovery.img
        fastboot erase cache
        fastboot reboot-bootloader

  
  
• You need your HTC drivers correctly installed on your PC:
  
  
  

  

  
  
  If not, follow this guide (thanks to nkk71):
  

  originally from @nkk71: [GUIDE] [02-MAR-2014] nkk71's SuperGUIDE to returning 100% back to stock
  
  follow the below instructions to fix
  
  Open "Device Manager" -> select the unknown "One" -> right-click -> "Update Driver Software ..." -> "Browse my computer" -> "Let me pick" -> "Android USB Devices" -> select "My HTC ..." -> install that
  

  just in case, HTC Drivers can be found here: [Drivers] HTC Drivers for Windows - Several Versions (credits to @mdmower)
  though you should already have them since you have been using your phone anyways
  
  for those who like a visual guide:
  

  
  okay so I did a fastboot boot command, and as you can see it didnt install correct driver
  

  

  
  
  
  Open "Device Manager"

  select Browse my computer for driver software
  

  

  
  
  
  select Let me pick from a list of device drivers on my computer
  

  

  
  
  
  select Android USB Devices

  warning, select Yes
