# Don't run rpi-update on production devices: it installs bleeding-edge firmware and kernels

> rpi-update installs pre-release kernel and firmware builds that may contain regressions. Raspberry Pi's own README says to use it only for testing or to get a specific pending fix; normal updates come through apt.

Old forum answers often say "run `sudo rpi-update`" to fix a problem. On a device that has to keep working, that's usually the wrong move.

## What it actually does

`rpi-update` replaces the kernel, kernel modules, firmware (and, unless skipped, the bootloader EEPROM images) with the **latest bleeding-edge builds**. Its own README says:

- There is **always the possibility of regressions**.
- Use it **only with a good reason**: to help test, or to get a **fix that has been pushed for a bug you're affected by**, until it arrives through normal releases.
- It's intended **only for Raspberry Pi OS**. With other distributions, and especially ones that ship a custom kernel, it's almost certainly not safe.
- **Back up before updating.**

Fixes reach Raspberry Pi OS through **`sudo apt update && sudo apt full-upgrade`** once they're considered well tested. That's the update path for production devices.

## If you really need it

```bash
sudo rpi-update                 # latest pre-release firmware + kernel
sudo rpi-update <git-hash>      # a specific revision from raspberrypi/rpi-firmware
sudo rpi-update pulls/<PR>      # build from a raspberrypi/linux pull request (kept 90 days)
```

Useful environment options from the README:

| Variable | Effect |
|---|---|
| `SKIP_BOOTLOADER=1` | update everything except the bootloader EEPROM images |
| `SKIP_KERNEL=1` | keep the kernel and modules (firmware may depend on a newer kernel, so use with care) |
| `ROOT_PATH=… BOOT_PATH=…` | offline update of a mounted SD card (set both or neither) |

To go back to the packaged bootloader images after an rpi-update, the README gives:

```bash
sudo rm -rf /lib/firmware/raspberrypi/bootloader-2711
sudo rm -rf /lib/firmware/raspberrypi/bootloader-2712
sudo apt reinstall rpi-eeprom
```

## For fleets

Test a pinned `rpi-update` revision on a few devices, not the whole fleet. Better still, wait for the fix in `apt` or build it into your own image (see the custom-image item), so every device runs a known, reproducible combination.

## Claims

- rpi-update is only intended for Raspberry Pi OS; on distributions with a custom kernel it is almost certainly not safe. (unverified)
- Kernel builds from raspberrypi/linux pull requests that rpi-update can install persist for 90 days. (unverified)
- rpi-update can install a specific firmware revision by Git hash from the raspberrypi/rpi-firmware repository. (unverified)
- rpi-update installs the latest bleeding-edge kernel and firmware, and its README states there is always the possibility of regressions. (unverified)
- The rpi-update README says to use it only with a good reason, such as helping with testing or getting a pushed fix for a bug you are affected by. (unverified)
