-`images/bananarchy-nokia-argon.img` (linked as `images/nokia-argon-sxmo.img`) — raw partitioned image (`256 MiB``ext2``pmOS_boot` + `ext4``pmOS_root`) ready for EDL flashing to `userdata` or raw `dd` to a microSD card.
-`images/boot-bananarchy-nokia-argon.img` (linked as `images/boot-nokia-argon-sxmo.img`) — standalone Android `boot.img` with Linux `6.12.1-msm8916`, initramfs, and appended DTB.
- Additional device images (`bananarchy-nokia-beatles.img`, `bananarchy-nokia-tough.img`, `bananarchy-nokia-sparkler.img`) can be generated at any time via `./rebuild-image.sh <device> --mkinitfs`.
- **Cross-compiled Xlibre (`X11Libre/xserver` 25.2.0)**: compiled specifically for ARMv7 Cortex-A7 (`-O2 -march=armv7-a -mtune=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -fno-plt -fomit-frame-pointer`) with all 3D/GLX/Glamor/VGA/DGA/XVideo bloat stripped out, rootless `elogind` device management, and `modesetting` KMS + `ShadowFB` (`drmModeDirtyFB` partial rectangle SPI updates) with automatic software cursor fallback on `/dev/dri/card0` (`panel-mipi-dbi`).
- **Non-Nerd `Fira Code` with OpenType ligatures**: `Fira Code` (`font-fira-code`) is configured as the primary system and terminal font across Fontconfig, Xft, `st`, `dmenu`, `dwm`, `conky`, and `dunst`, with `DejaVu SansM Nerd Font` used strictly as a fallback for Private Use Area icon glyphs.
- **Patched `sxmo-dmenu` (`dmenu`) (`< 15 ms` startup)**: full-width `240x320` 9-line vertical menu (`lineheight = 26`, positioned flush at `Y = 24` right below the 24px `dwm` bar) with a `#383838` top search bar, `#005577` prompt badge, `#1c1c1c` item list, `XIM` (`XSetLocaleModifiers("")`, `XSetICFocus`, `Xutf8LookupString`) for live `fcitx5-t9` search filtering and `#` mode switching, C-level focus preservation (`prevfocuswin`), and direct Nokia keypad bindings.
- **Patched `sxmo-dwm` (`dwm`) (`< 2 ms` display wake/unlock)**: configured for `240x320` (`bh = 24`, `#323232` top bar, `#005577` active tag/border, vertical `bstack` layout default, overflow-protected Pango status bar rendering keeping the right-aligned clock always visible). Directly polls `/dev/input/by-path/platform-gpio-keys-event` (`SW_LID`) and intercepts locked-state wake keys (`XF86PowerOff`, `XF86PickupPhone`, `XF86KbdLcdMenu1`, `XF86KbdLcdMenu2`) in C to toggle `/sys/class/backlight/backlight/brightness` and `/sys/class/leds/white:kbd_backlight/brightness` in `< 2 ms` before running Sxmo state hooks asynchronously.
- Supports 6 input modes cycled with `#` (`XF86NumericPound`): `abc`, `Abc`, `ABC`, `Sym`, `Ctl`, and `123`, updating the live top-bar status indicator (`[abc]`, `[Abc]`, `[ABC]`, `[Sym]`, `[Ctl]`, `[123]`) in real time.
- Locks the candidate popup bar to the bottom of the screen (`X = 1, Y = 290, W = 238, H = 30`) with fixed-width 28-character monospace formatting (`Fira Code 9.5`), so neither the popup window nor individual letters ever jump when cycling through candidates.
- Includes instant case toggling during preedit, full 32-character ASCII punctuation/symbol entry, terminal control sequences (`^A`–`^Z`, `Esc`, `Tab`, `F1`–`F12`), and a `550ms` long-press `*``Ctrl+` modifier latch.
- Fetched from the latest `master` branch of `https://code.luxferre.top/luxferre/bantam-cpp`, cross-compiled for `armv7`, and installed to `/usr/bin/bantam` and `/usr/local/bin/bantam` (with no default `.bantam.cfg` pre-created).
- Automatic PM8909 WCD analog codec register initialization at boot (`CDC_A_MICB_1_VAL``0xf141 = 0x60` for 2.8V internal MEMS microphone bias, and `CDC_A_RX_EAR_CTL``0xf1c0 |= 0x20` for +6 dB earpiece PA gain).
-`bananarchy-photo`: CLI and Sxmo menu camera utility (`Camera` in the Sxmo System and Apps menus) supporting instant JPEG/PNG photo capture, optional flash (`-f`), and `imv` photo viewing (`-v`).
3. Upload `bootloader/loaders/8110.mbn` via Sahara and connect to eMMC via Firehose.
4. Back up `gpt.bin`, `fsc`, `fsg`, `modemst1`, `modemst2`, `persist`, and `boot` into `./backup/` (if not already backed up).
5. Flash `lk2nd-msm8909.img` to `boot`, flash `images/bananarchy-<device>.img` to `userdata`, clear the stock `system` superblock, and reboot into Bananarchy Linux.

By default, Sxmo `dwm` is configured with the **vertical bottom-stack (`bstack`, `TTT`)** layout as default, so opening multiple `st` terminals stacks them **vertically (one terminal under another)** to maximize line width on the `240x320` portrait screen.
You can switch between **vertical stack (`TTT`, `bstack`)**, **horizontal tile (`[]=`, `tile`)**, **deck (`[D]`, `deck`)**, and **fullscreen monocle (`[M]`, `monocle`)** layouts — as well as switch focus between open terminals — using any of the following combos:
- **Short-press `#`** *(when no character is in preedit)*: cycles through the 6 input modes (`abc` -> `Abc` -> `ABC` -> `Sym` -> `Ctl` -> `123` -> `abc`), displaying a `1500ms` preedit status banner (`[Mode: abc]`, `[Mode: Abc]`, `[Mode: ABC]`, `[Mode: Sym]`, `[Mode: Ctl]`, `[Mode: 123]`).
- **Auto-commit timeout**: `1500ms` for keys with `<= 10` candidates, or `1800ms` for keys with `> 10` candidates (`1` and `*` in `abc`/`Abc`/`ABC`, `*` in `Sym`, `9` in `Ctl`). Pressing a different key immediately commits the active candidate.
- Press **`#`** or **D-Pad `Up`**: toggles letter case (`a` <-> `A`) on the fly without changing mode, or jumps forward **`+4` candidates** for non-alphabetic items.
- Press **D-Pad `Down`**: toggles letter case (`a` <-> `A`) for alphabetic items, or jumps backward **`-4` candidates** for non-alphabetic items.
- Press **D-Pad `Left`**: steps backward **1 candidate** on the same key.
- Press **D-Pad `Right`** or **Center `OK` (`Return`)**: commits the highlighted candidate immediately.
- Press **`BackSpace`**: cancels the uncommitted preedit candidate without deleting previously committed text.
- In `123` mode: commits a decimal point (`.`) immediately.
- In all other modes: toggles a one-shot **`Ctrl+` modifier latch** (`[Ctrl+ LATCH ON]` / `[Ctrl+ LATCH OFF]`; mode prefix shows `+^`, e.g. `abc+^`). The next committed key (`a`–`z`, `[`, `\`, `]`, `^`/`6`, `_`/`-`) is sent as `Ctrl+<key>`.
- **Hold `#`**: commits a literal `#` character immediately in any mode.
*(In `Abc` and `ABC` modes, uppercase letters precede the digit and lowercase letters on keys `2`–`9`. In `Abc` mode, committing an alphabetic character automatically reverts to `abc`.)*
Open the **System menu** (`Left softkey`) or **Apps menu** (`Left softkey` -> `Apps`) and select **Camera** (`bananarchy-photo --menu`). From the Camera menu you can:
- **Take photo**: capture a photo to `~/Pictures/photo-YYYYMMDD-HHMMSS.jpg` and immediately open it in `imv`.
- **Take photo (flash)**: turn on the rear flashlight (`white:torch`), capture a photo, restore the flashlight state, and open the photo in `imv`.
- **View photos**: browse all saved photos in `~/Pictures` using `imv` (press `Right softkey` inside `imv` to navigate, zoom, rotate, or quit).
- **From the CLI (`bananarchy-photo`)**:
```bash
# Capture to ~/Pictures/photo-YYYYMMDD-HHMMSS.jpg and print path
bananarchy-photo
# Capture with rear LED flash enabled and open in imv
- **Why `v4l2-ctl` + `ffmpeg -f rawvideo` is used under the hood**: Alpine's `libavdevice` links against `libv4l2.so.0`, whose `v4l2_mmap` wrapper on 32-bit ARM (`musl` 64-bit `off_t`) misaligns variadic `syscall(SYS_mmap2, ...)` arguments. Capturing via `v4l2-ctl` and encoding via `ffmpeg -f rawvideo` bypasses `libv4l2` completely.
Both the rear loudspeaker (`Speaker` / `SPK_OUT`) and the front earpiece speaker (`Earpiece` / `EAR`, boosted by +6 dB in `CDC_A_RX_EAR_CTL`), as well as the internal MEMS microphone (`Mic1` / `AMIC3`, biased at 2.8V in `CDC_A_MICB_1_VAL`) and 3.5mm headset microphone (`Mic2` / `AMIC2`), are managed through PipeWire/WirePlumber and `sxmo_audio.sh`:
- **List available audio outputs (`Speaker`, `Earpiece`, `Headphones`)**:
```bash
sxmo_audio.sh out list
```
- **Switch active output to the rear loudspeaker**:
```bash
sxmo_audio.sh out set "Speaker"
```
- **Switch active output to the front earpiece speaker**:
```bash
sxmo_audio.sh out set "Earpiece"
```
- **Record from the internal MEMS microphone (`Mic1`)**:
- **Inspect modem registration, operator, and signal quality**:
```bash
mmcli -m any
```
- **Place or manage voice calls and SMS**:
Use the Sxmo **Phone** / **Texts** menu (`Left softkey`) or `mmcli -m any --voice-list-calls` / `mmcli -m any --messaging-list-sms`. In-call audio is automatically routed between the modem (`VoiceMMode1`) and the PM8909 WCD codec by the `q6voiced` service and `sxmo_modemaudio.sh`.
