This ROM contains a minimal Debian Stretch installation that turns your old'n'broken cellphone in a raspberry pi-like server. This is NOT android with chroot, but a full-blown Debian installation. All android stuff including recovery is wiped.

HINT: This firmware may work on other MT6589-based devices with at least 4GiB eMMC.


Custom kernel (based on aquarius-HD5) with everything that makes systemd happy. What works: eMMC, usb client, frequency stepping (Other stuff not tested).

Custom simple initrd with recovery-like features

Debian Stretch is stripped to a bare minumum set of packages, install all you need via apt-get

Partition table is cleaned of useless partitions leaving only one for rootfs.

You don't need to press the power button to boot it – just plug in the battery and the usb cablle and you're good to go (suits even for junk with broken power button)

Boot sequence:

Custom initrd enables usb into a composite (serial port + ums + ethernet) mode and waits for ten seconds for an emergency login (e.g. if you screwed up and debian doesn't boot) on the virtual serial port. If nobody logged in – it mounts rootfs and boots debian

Debian tries to obtain an ip on the usb interface via DHCP (waits up to 5 minutes)

Debian enables a login shell on the virtual serial port.


Q: How to change network settings?
A: Login using virtual serial port and edit /etc/network/interfaces according to debian docs.

Know issues:

No eMMC usage optimization (yet)

Doesn't resize rootfs on first boot

Doesn't regenerate ssh keys or ask for timezone setting on first boot

Only DHCP version so far

LOGIN: root
PASSWORD: 12345678
DHCP HOSTNAME: eldershade

Warning! This is only a preview version, e.g. proof-of-concept. Debian is not optimized to make the best of eMMC and may wear it up quite fast. Please post your comments here or in the 4pda thread
