## How to update my RaspiBlitz (AFTER version 0.98)?
## How do I generate a Debug Report?
If your RaspiBlitz is not working right and you like to get help from the community, its good to provide more debug information, so other can better diagnose your problem - please follow the following steps to generate a debug report:
*Notice: Please be sure that your base image you started with was version 0.98 or greater. If you used the now deprecated XXupdateScripts.sh script to update before, you might have started with an older base image. If you never run that script, you're good.*
- ssh into your raspiblitz as admin user with your password A
- If you see the menu - use CTRL+C to get to the terminal
- To generate debug report run: `./XXdebugLogs.sh`
- Then copy all output beginning with `*** RASPIBLITZ LOGS ***` and share this
*PLEASE NOTICE: Its possible that this logs can contain private information (like IPs, node IDs, ...) - just share publicly what you feel OK with.*

## How to update a old RaspiBlitz (BEFORE version 0.98)?
If your old RaspiBlitz if version 0.98 or higher, just follow the update instructions in the README.
If you run a version earlier then 0.98 you basically need to setup a new RaspiBlitz to update - but you can keep the blockchain data on the HDD, so you dont need have that long waiting time again:
You need to setup a new RaspiBlitz. So close all channels. Remove all funds from your Raspiblitz (cash-out). Go into terminal and run: `sudo /home/admin/XXleanHDD.sh` and then `sudo shutdown now`. This way you keep your blockchain data on the HDD, but your HDD is cleaned. Now follow again: https://github.com/rootzoll/raspiblitz#scenario-2-start-at-home
1. Close all open lightning channels you have (`lncli closeallchannels --force`) or use the menu option 'CLOSE ALL' if available. Wait until all closing transactions are done.
## Why do I need to re-burn my SD card for an update (AFTER version 0.98)?
2. Move all on-chain funds to a wallet outside raspiblitz (`lncli --conf_target 3 sendcoins [ADDRESS]`) or use the menu option 'CHASH OUT' if available
3. Prepare the HDD for the new setup by running the script `/home/admin/XXcleanHDD.sh` (Blockchain will stay on HDD)
4. then shutdown RaspiBlitz (`sudo shutdown now`), flash SD card with new image, redo a fresh setup of RaspiBlitz, move your funds back in, Re-Open your channels
## Why do I need to re-burn my SD card for an update?
I know it would be nicer to run just an update script and you are ready to go. But then the scripts would need to be written in a much more complex way to be able to work with any versions of LND and Bitcoind (they are already complex enough with all the edge cases) and testing would become even more time consuming than it is now already. That's nothing a single developer can deliver.

# How does PASSWORD D effects this seed?
## How does PASSWORD D effects the word seed?
On wallet creation you get asked if you want to protect your word seed list with an additional password. If you choose so, RaspiBlitz recommends you to use your PASSWORD D at this point.
To use a an additional password for your seed words is optional. If you choose so, you will need the password to recover your private key from your your seed words later on. Without this password your private key cannot be recovered from your seed words. So the password adds an additional layer of security, if someone finds your written down word list.
## How can I recover my coins from a failing RaspiBlitz?
You might run into a situation where your hardware fails or the software starts to act buggy. So you decide to setup a fresh RaspiBlitz, like in the chapter above "Update to a new SD Card Release" - but the closing channels and cashing out is not working anymore. So whats about the funds you already have on your failing setup?
There is not a perfect way yet to backup/recover your coins, but you can try the following to make the best out of the situation:
### 1) Recover from Wallet Seed
Remember those 24 words you were writing down during the setup? Thats your "cipher seed" - now this words are important to recover your wallet. If you dont have them anymore: skip this chapter and read option 2. If you still have the cypher seed: good, but read the following carefully:
With the cypher seed you can recover the bitcoin wallet that LND was managing for you - but it does not contain all the details about the channels you have open - its just the key to your funding wallet. If you were able to close all channels or never opened any channels, then everything is OK and you can go on. If you had open channels with funds in there, the following is to consider:
* You now rely on your channel counter parts to force close the channel at one point. If they do, the coins will be available to use in your funding wallet again at one point in the future - after force close delay.
* If your channel counter parts never force close the channel (because they are offline too) your channel funds can be frozen forever.
So going this way there is a small risk, that you will not recover your funds. But normally if your channel counter parts are still online, see that you will not come back online and they have themselves some funds on their channel side with you: They have an incentive to force close the channel to make use of their funds again.
So here is what todo if you want to "Recover from Wallet Seed" with RaspiBlitz:
- SetUp a fresh RaspiBlitz (fresh SD-Card image and clean HDD).
- During the new SetUp you get to the point of creating the LND wallet (see image below).
- When you get asked "do you have an existing cypher wallet" answere `y` this time.
- Follow the dialog and enter the cypher seed.
- If you get asked at the end for the password D to encrypt your cypher seed, use the same as the last time. If you havent entered one last time, just press Enter again.
Then give LND some time to rescan the blockchain. In the end you will have restored your funding wallet. You maybe need to wait for your old channel counter parts to force close the old channels until you see the coins back displayed.
### 2) LND Channel State Backup
This second option is very very risky and can lead to complete loss of funds. And it olny can work, if you can still access the HDD content of your failing RaspiBlitz. It should only be used if you lost your cypher seed for the option above, forgot your cypher seed encryption password or your old channel counter parts are offline, too.
What you do is in priciple:
- Make a copy of the HDD directory `/mnt/hdd/lnd`
- Setup a fresh RaspiBlitz
- Stop LND with `sudo systemctl stop lnd`
- Replace the new `/mnt/hdd/lnd` with your backuped version
- Reboot the RaspiBlitz
This is highly experimental. And again: If you restore the LND with an backup that is not representing the latest channel state, this will trigger the lightning "penalty" mechanism - allowing your channel counter part to grab all the funds from a channel. Its a measure of last resort. But if its working for you, let us know.
## How do I change the Name/Alias of my lightning node

## Why is my node address on the display yellow (not green)?
Yellow is OK. The RaspiBlitz can detect, that it can reach a service on the port 9735 of your public IP - this is in most cases the LND of your RaspiBlitz. But the RaspiBlitz cannot 100% for sure detect that this is its own LND service on that port - thats why its just yellow, not green.

## I dont have an LAN router - how to connect to my RaspiBlitz?
To connect a RaspiBlitz directly (without a router/switch) to your laptop and share the WIFI internet connection, you can follow this [guide for OSX](https://medium.com/@tzhenghao/how-to-ssh-into-your-raspberry-pi-with-a-mac-and-ethernet-cable-636a197d055).
In short:
* make sure all VPN are off (can interfere with local LAN)
* connect with LAN directly
* Settings > Sharing/Freigaben > activate "internet sharing" from WLAN to Ethernet
* Settings > Network > Ethernet-Adapter > set to DHCP
* in terminal > `ifconfig` there you should the the IP of the bridge100
* in terminal > `arp -a` and check for an IP of a client to the bridge
* in terminal > ssh admin@[clientIP]
If anyone has expirence on doing this in Linux/Win, please share.
## How do I unplug/shutdown safely without SSH
Just removing power from the RaspiBlitz can lead to data corruption if the HDD is right in the middle of a writing process. The safest way is always to SSH into the RaspiBlitz and use the "POWER OFF" option in the main menu.
But if cannot login with SSH and you need to power off at least remove the LAN cable (network connection)first for sometime (around 10-30 secs - until you can see no more blinking lights on the HDD) and then remove the power cable. This should minimize the risk if data corruption in this situations.
## How can I build an SD card other then the master branch?
There might be a new not released features in development that are not yet in the master branch - but you want to try them out.
To build a sd card image from another branch than master you follow the [Build the SD Card Image](README.md#build-the-sd-card-image) from the README, but execute the build script from the other branch and add the name of that branch as a parameter to the build script.
For example if you want to make a build from the 'dev' branch you execute the following command:
## How can I build an SD card from my forked GitHub Repo?
If you fork the RaspiBlitz repo (much welcome) and you want to run that code on your RaspiBlitz, there are two ways to do that:
* The quick way: For small changes in scripts, go to `/home/admin` on your running RaspiBlitz, delete the old git with `sudo rm -r raspiblitz` then replace it with your code `git clone [YOURREPO]` and `/home/admin/XXsyncScripts.sh`
* The long way: If you like to install/remove/change services and system configurations you need to build a SD card from your own code. Prepare like in [Build the SD Card Image](README.md#build-the-sd-card-image) from the README but in the end run the command:
If you are then working in your forked repo and want to update the scripts on your RaspiBlitz with your latest repo changes, run `/home/admin/XXsyncScripts.sh` - thats OK as long as you dont make changes to the sd card build script - then you would need to build a fresh sd card again from your repo.
## What other case options do I have?
You can replace the generic case in the shopping lists with a customized 3D printed for the RaspiBlitz called "Lightning Shell" - great work by @CryptoCloaks
Also there are first free 3D open source files in this repo in the directory `case.3dprint` that you can selfprint. Those are much simpler then the 'Lightning Shell' and are not finished yet. But feel free to try out and improve - PullRequests welcome.

Until we reach version 1.0 the update process will be a bit rough .. so what you do is:

* wait until all closing transactions are done
* move all on-chain funds to a wallet outside raspiblitz (`lncli --conf_target 3 sendcoins [ADDRESS]`)

* shutdown RaspiBlitz (`sudo shutdown now`)
* flash SD card with new image
* Redo a fresh setup of RaspiBlitz
* Move your funds back in
* Re-Open your channels
We know that this is not optimal yet. But until version 1.0 we will change too much stuff to garantue any other save update mechanism. Also by redoing all the setup you help out on testing the lastest setup process.
From the upcomming version 1.0 onwards the goal is to make it easier to keep up with the lastest RaspiBlitz updates.
## Recover your Coins from a failing RaspiBlitz
You might run into a situation where your hardware fails or the software starts to act buggy. So you decide to setup a fresh RaspiBlitz, like in the chapter above "Update to a new SD Card Release" - but the closing channels and cashing out is not working anymore. So whats about the funds you already have on your failing setup?
There is not a perfect way yet to backup/recover your coins, but you can try the following to make the best out of the situation:

* You now rely on your channel counter parts to force close the channel at one point. If they do, the coins will be available to use in your funding wallet again at one point in the future - after force close delay.
* If your channel counter parts never force close the channel (because they are offline too) your channel funds can be frozen forever.

So going this way there is a small risk, that you will not recover your funds. But normally if your channel counter parts are still online, see that you will not come back online and they have themselves some funds on their channel side with you: They have an incentive to force close the channel to make use of their funds again.

So here is what todo if you want to "Recover from Wallet Seed" with RaspiBlitz:
- SetUp a fresh RaspiBlitz (fresh SD-Card image and clean HDD).
- During the new SetUp you get to the point of creating the LND wallet (see image below).
- When you get asked "do you have an existing cypher wallet" answere `y` this time.
- Follow the dialog and enter the cypher seed.
- If you get asked at the end for the password D to encrypt your cypher seed, use the same as the last time. If you havent entered one last time, just press Enter again.
Then give LND some time to rescan the blockchain. In the end you will have restored your funding wallet. You maybe need to wait for your old channel counter parts to force close the old channels until you see the coins back displayed.
### 2) LND Channel State Backup
This second option is very very risky and can lead to complete loss of funds. And it olny can work, if you can still access the HDD content of your failing RaspiBlitz. It should only be used if you lost your cypher seed for the option above, forgot your cypher seed encryption password or your old channel counter parts are offline, too.

- Reboot the RaspiBlitz
This is highly experimental. And again: If you restore the LND with an backup that is not representing the latest channel state, this will trigger the lightning "penalty" mechanism - allowing your channel counter part to grab all the funds from a channel. Its a measure of last resort. But if its working for you, let us know.

## Further Development of RaspiBlitz
The RaspiBlitz was developed on the basis of the RaspiBolt Guide to run LND on a RaspberryPi: https://github.com/Stadicus/guides/blob/master/raspibolt - the idea was to prepare as much as possible and have it on a SD-card ready to startup quickly. The configuration should be automated by scripts combined with some very basic user interaction thru the terminal for adminstration. The LCD should provide basic information, so that the health and state of the RaspiBlitz could be monitored with ease. The LCD has also basic touch support and could be used for direct and fast daily interactions.
The goal of the RaspiBlitz is to provide a out-of-the-box hardware lightning node to learn the basics of being part of the decentralized network and to quickly start building your own applications based on lightning (LApps) - at home or at educational/hacking events. With the well known [GPIO-Pins](https://www.raspberrypi.org/documentation/usage/gpio/) of the RaspberryPi, low-cost entry point and its rich hardware extension ecosystem it seems like the perfect device to foster the communities creativity. Lets keep crypto weird.
Everybody is welcome to join, improve and extend the RaspiBlitz - its a work in progress. Check the issues if you wanna help out or add new ideas. You find the scripts used for RaspiBlitz interactions on the device at `/home/admin` or in this git repo in the subfolder `home.admin`. More to come.

Check it out on: [dietpi.com](https://dietpi.com)
Issues:
* Setup is not automated yet - more steps required than running on Raspbian.
* There is no LCD support yet on DietPi.
See the instructions using DietPi for multiple kind of hardware: [dietpi/README.md](dietpi/README.md)
after installing DietPi and building the SDcard the setup continues from [Documentation](#documentation))
