|

Make sure you have installed a firmware with BTADDON compiled.
|

## Compiling and Flashing a Proxmark3 Firmware from non-root Android
|
||||
|
||||
READ ME:
|
||||
* If you can compile and flash your device from a PC, do it! It's probably much confortable than following this method.
|
||||
* Flashing is possible only via USB-UART, *not* via BT-UART
|
||||
* Avoid flashing the Bootloader from non-root Android as the connection is probably less stable than with pure USB and you don't want to brick your device...
|
||||
|
||||
### Compiling the Proxmark3 Firmware
|
||||
|
||||
Assuming we're using the Github repo sources as explained above.
|
||||
|
||||
```
|
||||
pkg install make clang readline libc++ git binutils
|
||||
cd
|
||||
git clone https://github.com/RfidResearchGroup/proxmark3.git
|
||||
cd proxmark3
|
||||
make clean && make -j client
|
||||
```
|
||||
|
||||
Termux doesn't have the ARM cross-compiler, so we'll install a Debian within Termux with https://github.com/sp4rkie/debian-on-termux
|
||||
|
||||
```
|
||||
$ pkg install debootstrap proot wget
|
||||
$ wget -q https://raw.githubusercontent.com/sp4rkie/debian-on-termux/master/debian_on_termux_10.sh
|
||||
$ sh debian_on_termux_10.sh
|
||||
```
|
||||
When launched the first time, the script will install the Debian. If called later, it will reuse the same installation and will be much quicker.
|
||||
At this point we should be on a Debian root prompt. We install only the requirements to compile the Proxmark3 firmware.
|
||||
```
|
||||
# apt-get install -y --no-install-recommends make gcc g++ libc6-dev gcc-arm-none-eabi libnewlib-dev
|
||||
# cd /data/data/com.termux/files/home
|
||||
# cd proxmark3
|
||||
# make -j fullimage
|
||||
# exit
|
||||
```
|
||||
At this point we're back to the Termux prompt.
|
||||
|
||||
### Flashing the Proxmark3 Firmware
|
||||
|
||||
Plug the Proxmark3 while pressing the button, to enter into bootloader mode manually.
|
||||
|
||||
Activate the USB-UART to TCP Bridge with one of the applications as explained above.
|
||||
|
||||
```
|
||||
cd proxmark3
|
||||
./client/proxmark3 tcp:localhost:<chosenPort> --flash --image armsrc/obj/fullimage.elf
|
||||
```
|
||||
Once the Proxmark3 has rebooted, reconnect it to the bridge in the app.
|
||||
The freshly flashed device is now ready to be used.
|
||||
|
||||
```
|
||||
./client/proxmark3 tcp:localhost:<chosenPort>
|
||||
```
