-This stick supports dual boot.
-
-`k0` and `r0` respectively contain the kernel and firmware of the first image, `k1` and `r1` the kernel and the firmware of the second one
-
-# List of firmwares and files
-## Useful files
-- `/var/config/lastgood.xml` - Contains the user portion of the configuration
-- `/var/config/lastgood-hs.xml` - Contains the "hardware" configuration (i.e. that _should_ not be changed)
-- `/tmp/omcilog` - OMCI messages logs (must be enabeled, see below)
-
-## Useful binaries
-- `/etc/scripts/flash` - Used to manipulate the config files in a samewhat safe manner
-- `xmlconfig` - Used to low-level manipulate the XML config files. Called by `flash`
-- `nv` - Used to manipulate the nvram storage, including persistent config entries via `nv setenv`/`nv getenv`
-- `omcicli` - Used to interact with the running OMCI daemon
-- `omci_app` - The OMCI daemon
-- `diag` - Used to run low-level diagnostics commands on the stick
-
-# Useful Commands
-
-## Getting/Setting the ONT's S/N
-```sh
-# /etc/scripts/bin flash get GPON_SN
-GPON_SN=TMBB00000000
-# /etc/scripts/bin flash set GPON_SN TMBB0A1B2C3D
-```
-
-## Getting/Setting the ONT's PLOAM password
-
-{% include alert.html content="The PLOAM password is stored in ASCII format" alert="Info" icon="svg-info" color="blue" %}
-
-```sh
-# /etc/scripts/bin flash get GPON_PLOAM_PASSWD
-GPON_PLOAM_PASSWD=AAAAAAAAAA
-# /etc/scripts/bin flash set GPON_PLOAM_PASSWD AAAAAAAAAA
-```
-
-## Enabling the Web UI
-```sh
-# /bin/iptables -D INPUT -p tcp --dport 80 -j DROP
-```
-
-## Checking the currently active image
-```sh
-# nv getenv sw_active
-sw_active=1
-# nv getenv sw_version0
-sw_version0=V1_7_8_210412
-# nv getenv sw_version1
-sw_version1=V1_7_8_210412
-```
-
-## Booting to a different image
-```sh
-# nv setenv sw_commit 0|1
-# reboot
-```
-
-## Querying a particular OMCI ME
-```sh
-# omcicli mib get MIB_IDX
-```
-
-# Low Level Modding
-
-{% include alert.html content="This section is based on `V1_7_8_210412` firmware version of the stick" alert="Info" icon="svg-info" color="blue" %}
-
-
-## Transfering files from/to the stick
-Works with binary files too, just run md5sum on source and destination to make sure you are not corrupting anything...
-From the stick to the PC:
-```sh
-# ssh admin@192.168.2.1 "cat /tmp/omcilog" > omcilog.log
-```
-From the PC to the stick
-```sh
-# cat lastgood.xml | ssh admin@192.168.2.1 "cat > /var/config/lastgood.xml"
-```
-
-{% include alert.html content="If a Windows system is used replace type with cat and run the commands from cmd (not Powershell)" alert="Info" icon="svg-info" color="blue" %}
-
-## Extracting and repacking the rootfs
-{% include alert.html content="Make sure you run both commands as root, otherwise you might get a damaged rootfs image" alert="Warning" icon="svg-warning" color="red" %}
-
-```sh
-# unsquashfs mtd5.bin
-# mksquashfs squashfs-root rootfs -b 131072 -comp lzma -no-recovery
-```
-## Flashing a new rootfs
-
-{% include alert.html content="Only the inactive image can be flashed" alert="Info" icon="svg-info" color="blue" %}
-
-So mtd4/5 if you are on image1, mtd6/7 if you are on image0.
-
-The follwing examples flashes a new rootfs to image1 and boots to it
-```sh
-# flash_eraseall /dev/mtd7
-# cat /tmp/rootfs.new > /dev/mtd7
-# nv setenv sw_commit=1
-# reboot
-```
-## Adding support to configurable SW and HW versions, VENDOR ID and much more
-`/etc/scripts/flash` can be flashed in order to add support for some variables implemented in `omci_app` but removed from `xmlconfig`. The patch is below (change the values to suit your needs)

-## Increasing the length of the software version from 13 to 14 characters
-`omci_app` has an hard-coded limit of 13 characters for the software version, which is too low. We can binary patch it to increase it to 14 (or more, if you dare/need)

-# xdelta patch omci_app.xdelta bin/omci_app bin/omci_app.new
-# mv bin/omci_app.new bin/omci_app

-For reference, the patch changes the follwing section of the omci_app:

-(It's inside the function referecing the string `OMCI_SW_VER1`)

-The original file md5sum is: `4aea2f72bacc11256b7e2c1583d2ad4f`
-The patched file md5sum is: `da20327c4c002e4c27f82f6ee63dbc1a`
-## Enabling PLOAM logging
-```sh
-/etc/scripts/bin flash set OMCI_DBGLVL 1
-/etc/scripts/bin flash set OMCI_DBGLOGFILE 1
-reboot
-/bin/omcicli set logfile 1 ffffffff
-```
-1. The binary log will be placed inside: `/tmp/omcilog`
-2. You can convert it into .pcap using [omcilog2pcap](https://github.com/ADeltaX/omcilog2pcap)
-3. You can then open it with Wireshark by installing the OMCI plugin from [wireshark](https://wiki.wireshark.org/Contrib.md)
-
-If you want to log everything since the stick boots, you can create a custom rootfs. Place the last command inside `etc/runomci.sh` as the last line of the file
