This is a quick guide that'll explain how to fix or enable ADB and MTP in custom recovery e.g TWRP

Requirements

• TWRP recovery, you can port TWRP for your device
  
• Notepad++ ; download @ https://notepad-plus-plus.org/downloads/
  
• Android image kitchen (AIK) ; download @ https://forum.xda-developers.com/showthr...?t=2073775
  

Steps on how to fix or enable ADB and MTP in TWRP recovery

Follow the steps below to fix or enable ADB and MTP in TWRP recovery

1. Extract your twrp recovery.img using AIK tool (drag and drop onto the unpackimg.bat)
   
   
2. If successful, open the \ramdisk folder and edit the file below using a text editor e.g Notepad++
   • For android 7 and below, edit default.prop
     
   • For android 8 and above, edit prop.default
     
   
   
3. Search for the following items below one after the other and if they exist then modify their values (see the next step for the right values to use)
   
   Code:

   ro.secure
ro.adb.secure
ro.debuggable
persist.sys.usb.config
sys.usb.config
   
   
4. If they don't exist then add each item in a new line as seen below
   
   Code:

   ro.secure=0
ro.adb.secure=0
ro.debuggable=1
persist.sys.usb.config=adb,mtp
sys.usb.config=adb,mtp
   
   
   
   
   
   
5. Repack the TWRP by running the repackimg.bat script
   
   
6. Finally, flash and boot into TWRP then confirm if both ADB and MTP work
   

Important Notice

• This might also work for other custom recoveries such as CWM / Philz. You can try to find out yourself
