+### Installation using IP Cam DMS (no flash soldering)
 
 * Download, unzip the archive and run the [IP Cam DMS](https://team.openipc.org/ipcam_dms/IPCam_DMS_20201121_EN.zip) program, which allows you to control the camera using the camera manufacturer's protocol.
 * Download the [special archive](https://github.com/OpenIPC/coupler/releases/download/latest/000659A7_fpv_IPC_GK7205V200_50H20AI_S38.bin) and perform a firmware upgrade, which will effectively make a seamless transition from the original firmware to OpenIPC.
 
-### Installation on camera (flash replacement option)
+> Note! Despite the fact it is the easiest way to flash firmware it has few disadvantages:
+> * It won't backup a stock firmware. There are chances you need the backup to extract some important parameters from the stock firmware. So even if you are 100% sure you don't need the stock firmware it's still a good idea to have a backup.
+> * In fact there is a prebuild fpv version only for IPC_GK7205V200_50H20AI_S38 board. For other boards you need to find and flash the lite version first. So that makes no sense using this installation type for other than IPC_GK7205V200_50H20AI_S38 boards.
 
-* Turn off the camera, unsolder the original 8 megabyte SPI NOR flash chip and dump it with a programmer just in case. It is desirable to unsolder the chip with [hair dryer](https://aliexpress.com/item/32980690787.html), but if you really want you can use a regular soldering iron [as Alexey Tolstov suggests](https://www.youtube.com/watch?v=M69JiBtuqq8) or [like this](https://www.youtube.com/watch?v=dspjVDv7hck). After unsoldering of the chip, the pads should be well cleaned from solder residue with a piece of copper cable.
+### Installation using burn (no flash soldering)
-When working with a hair dryer it is desirable to remove the lens and insulate the other components, especially the plastic connectors with [kapton tape](https://aliexpress.com/item/1005003563721341.html) (in extreme case with chocolate bar foil). Never [use Rose alloy](https://habr.com/ru/post/437778/). If you're not very good with a finger, it's easier to go to the nearest cell phone repair service and show the master a part of this manual.

+This will work even in case you have locked bootloader or flashed wrong bootloader to the SPI flash.
+* On the workstation, install a TFTP server
+* Find your SoC on [openIPC][supported_hardware] and Generate `Installation Guide` (note: select NOR 8M memory chip even if you have 16M or 32M chip since there is no fpv versions for those configurations. Don't worry after the first boot the overlay fs will be expanded.)
+* There is a video tutorial for the [burn][github_burn] utility: [OpenIPC BURN Utility Playlist][youtube_burn] . Just select the video for your OS and follow the guide.
+* At the end of the video tutorial you will be at the terminal with unlocked bootloader. Don't close it, you will need it further.
+* Make sure the TFTP server is run and you downloaded OpenIPC firmware from the `Installation Guide` to the proper place
+* Follow the `Installation Guide` from the second step to:

 * After booting the system, verify that it has obtained an IP address via Ethernet (it can be accessed via SSH via root@<IP address of the camera> without a password). Using a modern operating system and the name `openipc.local` you can find the camera within the local network without knowing its IP address. 
 * Solder GND, DP and DM to the USB pads (USB 5V power supply should not be connected to the board due to the high power consumption of the adapter), and separately 5V and GND to power the WiFi adapter (possibly via an additional DC-DC converter depending on your circuit). The USB wire that comes to the board should be secured with a cable tie to avoid breaking off the pins on the contact pad:
