Create a Kali Linux Bootable USB from Your Android Phone
No PC needed — flash a live Kali Linux USB using only your Android phone and EtchDroid app.
Did you know you can create a bootable Kali Linux USB drive using just your Android smartphone? With the free EtchDroid app and a USB OTG adapter, you can flash any ISO directly from your phone — no laptop or PC required. This guide walks you through every step with screenshots.
⚙ What You Need Before Starting
Flashing will completely erase all data on your USB pendrive. Back up any important files before proceeding.
#1 Download the Kali Linux ISO File
First, download the official Kali Linux ISO on your Android phone. Always use the official Kali Linux website to avoid fake or malware-infected ISO files.
https://www.kali.org/get-kali/#kali-live → Choose: Kali Linux 64-Bit (Live) → File size: ~4.0 GB → Format: .iso
- Open your phone browser and go to kali.org/get-kali
- Tap on "Kali Linux 64-Bit Live" — this is the bootable version
- Wait for the download to complete (it's ~4 GB, use Wi-Fi)
- Note where the file saved (usually Downloads folder)

After downloading, verify the SHA256 checksum on the Kali website to confirm the file is not corrupted.
#2 Install the EtchDroid App
EtchDroid is a free, open-source app that lets you write disk images and ISO files to USB drives directly from Android. It's the most reliable tool for this job.
- Open the Google Play Store on your Android phone
- Search for "EtchDroid" — look for the blue USB icon
- Tap Install and wait for it to download
- Once installed, tap Open

It is open-source (GitHub verified), has millions of downloads, and requires no root access on most devices.
#3 Connect Your USB Pendrive via OTG
This is the step most beginners miss — you cannot plug a USB drive directly into your phone. You need an OTG (On-The-Go) adapter to connect them.
- Get your USB OTG adapter (USB-C to USB-A, or Micro-USB to USB-A)
- Plug the OTG adapter into your phone's charging port
- Plug your USB pendrive into the OTG adapter
- Your phone should show a notification that a USB device is connected
- Tap "Allow" if Android asks for USB access permission

Check your phone specs online — search "your phone model + OTG support". Not all budget phones support OTG. You can also use a free app like "USB OTG Checker" from Play Store to verify.
#4 Flash the ISO Using EtchDroid
Now the main part — open EtchDroid and write the Kali Linux ISO to your pendrive. Follow these sub-steps carefully.
- Open EtchDroid app
- Tap "Write a disk image or zip"
- Navigate to your Downloads folder and select the Kali Linux
.isofile - EtchDroid will automatically detect your connected USB pendrive — tap on it
- Review the warning — it will erase the pendrive. Tap "Write" to confirm
- Grant USB access permission when Android prompts you
- Wait for the flashing to complete — this takes 10–30 minutes
- Do NOT unplug the pendrive until you see the success message
