The PinePhone is a smartphone created by Pine64, capable of running mainline Linux and supported by many partner projects. The "BraveHeart" edition was the first publicly-available version of the phone, though it came without a fully functional OS (factory test image) and was geared specifically towards tinkerers and hackers. People looking for a stable consumer-grade phone should wait for the final release, which is expected to occur in March 2020 and will be available for at least five years.
"BraveHeart" PinePhone Unboxing and First Time Preparation Guide
From the factory the battery has a sticker on it that isolates the battery from the phone. The battery will not charge until this is removed.
After unboxing remove the back panel. Then remove the battery and peel off the clear plastic below it that isolates the charging contact. Then replace the battery.
If you power on the phone the factory test image will boot. RTL8723CS (WiFi modem) will fail unless there is a WiFi network in range for it to see and the battery is charged. EG25 will fail until battery is changed.
By default there is no true OS image installed on Braveheart phones. An SD card with a bootable image needs to be inserted into the phone. See section 12 below for a list of OS options. Note the SD and sim sockets are stacked on each other The SD slot is the "shallower" socket and the SIM card goes in the "deeper" socket.

List of devices working with the PinePhone (depending on OS support)
The PinePhone has 6 "pogo pins" on the back allowing for custom hardware extensions such as wireless charging or an IR blaster. The pogo pins provide access to an interrupt line, power input to charge the battery, 3.3v power source, and an I2C interface.
A step/stl/stp (3D model) file for the back cover is freely available for creating custom cases that interface with the pogo pins.
The PinePhone has a serial port in the headphone connector, it's activated by the 6th contact on the dipswitch. If the switch is on then the headphone connector is in audio mode, if it's off then it's in UART mode.
The uart is 115200n8
The pinout for the serial connector on the tablet side is:
- Tip: RX
- Ring: TX
- Sleeve: GND
The serial connection is 3.3V
You can also buy the debug cable from PINE64 Store The store cable uses a 4 ring plug, as seen in the PDF, but a 3 ring plug works just as well. That cable uses a CH340 chipset based serial to USB converter, but any 3.3v serial connection can be used.
The PinePhone features six switches that can be used to configure its hardware. They are numbered 1-6, with switch 1 located nearest to the modem. Their on position is toward the top of the phone.
- Modem: On enables 2G/3G/4G communication and GNSS hardware, off disables.
- WiFi/BT: On enables Wi-Fi and Bluetooth communication hardware, off disables.
- Microphone: On enables audio input from on-board microphones (not 3.5mm jack), off disables.
- Rear camera: On enables the rear camera, off disables.
- Front camera: On enables the front camera, off disables.
- Headphone: On enables audio input and output via the 3.5mm audio jack, off switches the jack to hardware UART mode.
The supplied battery is meant to be compatible with Samsung part number EB-BJ700BBC / BBE / CBE from the 2015 J7 phone. There is a report that the EB-BJ700CBE isn't quite the same size, causing the back not to fit properly.
The battery terminals, in order from nearest the edge to nearest the middle, are:
- not connected
The battery includes a protection circuit that isolates it in a number of fault conditions, including if it is discharged too far. The fully discharged battery can be recharged by connecting the phone to a charger. Once it has charged sufficiently you will be able to boot the phone.
If your battery is hard to remove from the phone, try loosening the screws around it. Possibly cutting up a piece of plastic and sliding it under the battery as a pull tab can work too.
When you first receive your Pinephone you will need to remove the plastic tab under the battery terminals to boot it. This is to protect it from turning on during shipping.
It's also important to note that the EG25 modem and RTL8723CS wifi/bluetooth do not work without the battery plugged in, even if you are supplying enough power to the Pinephone with USB-C
Modem and Carrier Support
To check if the PinePhone is supported on your carrier:
It is likely that there will be a few frequencies that your carrier uses which are not supported by the PinePhone. Not all of the carrier's frequencies need to be supported by the PinePhone for it to work - as long as most of them are supported, you will still get good coverage.
Factory Test Requirements
Most of the self tests should just work, but a couple of them will fail unless certain requirements are met.
RTL8723CS - WiFi
- The self test needs a visible access point nearby so it can discover an SSID.
- The self test may fail if the battery charge is too low.
EG25 - Modem
- A working micro-SIM that doesn't require a PIN to unlock
- Enough battery charge
The PinePhone will automatically boot from microSD if a bootable card is inserted. Although it is technically possible to use any ARM distro (because the PinePhone uses the mainline kernel), there are a few that are designed specifically for phones. Under 'Pinebook Pro Software and OS Image Download Section' you will find a complete list of currently supported Operating System images that work with the Pinebook as well as other related software.
