Phones

Health, last connection, and everything stored on this PC. Plug in for a USB backup, trigger one over the internet, Find My J, or copy a phone onto a new one.

Link a phone to JCloud

  1. USB (best for full backup): plug in a data cable. If the phone asks, tap Allow. USB debugging can stay on — then Backup.
  2. Wi‑Fi: every app talks through JCloud. Encrypted slices wait, retry, and shrink if the signal drops — same send/save/receive path for photos, apps, and notes.

JCloud

This PC is the cloud for your phones. Each phone has its own folder. Plug in USB, or open the phone link on Home.

Checking…

USB backup copies the whole phone under the active device. Offload only frees space in the folders listed in Settings — it will never wipe the entire phone.

Devices

Name each phone. JCloud tracks storage used on this PC and the latest backup per device. Plug in a phone and tap Use for backups (or bind its adb serial) so the right folder is used.

Settings (schedule, folders)
Wireless sync (token)

Token (send as header X-JCloud-Token). All apps use JCloud Link — AES-256-GCM slices that resume and shrink on a weak signal: …

Over Tailscale Funnel the phone can hit this Phones app and upload files without USB. USB/adb backup is still the simplest full pull of Photos/Download/etc.

Vault for this device

Offload moves folders to this PC and deletes them on the phone. Phone app: install JCloud from the App Store, then open the phone link on Home (it pastes this PC’s URL + token). Mobile page: /jcloud-app

Recorder

Voice or type. Saves into J Notes on this PC so Jill and the Notes phone app can read it.

J Maps · Hey Jarvis

The phone app is J Maps in the catalog. Hey Jarvis here can add calendar events and send ideas to J Notes.

J Calendar

Each phone user has their own calendar. New events are sole (private) unless you share them. Paste dumps and Hey Jarvis live in the full app.

Standalone apps

Jarvis, Clip, and Jill work on house Wi‑Fi and cellular through this PC’s public HTTPS. Clip and Jill still run on the mini PC. Standalone apps ship all UI inside the APK and run offline on the phone.

  • Notes — offline notepad (com.chris.notes) in the App Store when built.
  • Template: phone-tools/apps/StandaloneNotes (and copy for new apps — leave Capacitor server.url empty so assets stay local).
  • Rule of thumb: if it must work on a plane with no PC, build it standalone and put the APK in the store.

Drivers Windows needs

USB IDModeWhat you need
VID_18D1&PID_4E11 / 4EE1ADB / AndroidGoogle USB / Android ADB Interface — adb devices
VID_18D1&PID_D00DFastboot / bootloaderWinUSB with Google GUID — fastboot devices

What failed on this PC (and the fix)

  • Stock Google android_winusb.inf does not list FP6 fastboot PID_D00D → yellow Android in Device Manager.
  • Zadig installs WinUSB but often with the wrong DeviceInterfaceGUID → device looks OK, fastboot hangs on “waiting for any device”.
  • GUID can reset every time the phone re-enters fastboot → re-run the fix.

Correct Google fastboot GUID:

{F72FE0D4-CBCB-407d-8814-9ED673D0DD6B}

Phone in bootloader, then run elevated:

~/Desktop/Phones/phone-tools/fix-fastboot-guid.bat

Or PowerShell (Admin):

powershell -ExecutionPolicy Bypass -File ~/Desktop/Phones/phone-tools/fix-fastboot-guid.ps1
fix-fastboot-guid.bat

Troubleshooting

SymptomLikely causeFix
adb shows unauthorized RSA prompt not accepted Unlock phone → Allow USB debugging (Always allow)
adb devices empty Cable / driver / not in Android Data cable, another port, enable USB debugging
Bootloader menu but fastboot devices empty Missing or wrong WinUSB GUID Device Manager → Android VID_18D1&PID_D00D → run fix-fastboot-guid
fastboot OKAY but still locked On-phone confirm not done Select Unlock bootloader / Unlock critical with Vol Up + Power
Keeps restarting after unlock Wipe / first boot chaos Force off → Vol Down+Power → stay on menu → finish unlock_critical / flash
/usr/bin/env: bash: No such file Git Bash shebang bash ./flash_FP6_factory.sh
Critical unlock check fails unlock_critical not confirmed Repeat unlock_critical; fastboot oem device-info must show critical unlocked: true
Phone on welcome setup mid-process Wipe reboot Skip setup; get USB debugging or force bootloader — flashing will wipe again

Instructions for Jarvis (agent)

  1. Work from ~/Desktop/Phones/phone-tools/platform-tools.
  2. Check adb devices and PnP VID_18D1. If unauthorized → tell user to tap Allow.
  3. adb reboot bootloader. Poll for PID_D00D. If fastboot empty but Android USB present → run elevated fix-fastboot-guid.ps1, then retry.
  4. Unlock / unlock_critical only with clear “confirm on phone” prompts. Expect wipes and temporary disconnects.
  5. Flash with Git Bash: bash ./flash_FP6_factory.sh from C:\flash\fp6-eos (or re-extract zip). Log output. Wait for EXIT 0.
  6. Tell user first /e/OS boot can take 5–10 minutes. Do not relock unless asked + SPL checked.
  7. Update this page / JARVIS-PHONE.md if a new gotcha appears on the next phone.

Unlock (wipes)

# On phone: Unlock the bootloader → Vol Up → Power

.\fastboot.exe flashing unlock_critical
# On phone: confirm again

cd /c/flash/fp6-eos
# or: tar extract zip to that folder first

Anti-rollback

Note stock SPL before unlock. /e/OS rollback ≈ 5th of its SPL month. Only relock if /e/OS rollback ≥ previous stock SPL. Prefer leave unlocked.
