## Recovery image preparation
The recovery image is used to replace the stock firmware with OpenWRT via
TFTP. Citing the MR200 OpenWRT
[manual](https://openwrt.org/toh/tp-link/archer-mr200):
> Turn on the device while pushing the WPS button until the WPS light turns
> on. At that point, the bootloaders integrated tftp client with the ip
> address of 192.168.1.1, tries to connect to a tftp server running at

> **ArcherC2V1_tp_recovery.bin**. so you need to be running a tftp server
> with the ip/netmask of 192.168.0.66/23 and connect it to lan port1. It is
> vital that your firmware includes the bootloader at the very beginning
> (without any extra tp-link header) as the bootloader will start writing
> the firmware to flash with the starting address of 0x00000000.

## Revert to TP-Link stock firmware
**Important:** Always revert back to the same stock firmware version which
was used to prepare the recovery image.
To avoid the possibility that the firmware file will be un-published fro
mthe vendor, it is stored is stored in the [firmware](./firmware) folder in
this repository. There is also an `extracted_firmware.bin` created out of
this stock firmware, should the ned to revert back be required (for
instance to install newer firmware released by the vendor, that would
update the 4G router firmware as well - something OpenWRT cannot do).
**Attention:** following this step can possibly brick the device. Double
check everything before proceeding! Citing the MR200 OpenWRT

scp extracted_firmware.bin root@openwrt:/tmp
/usr/bin/ssh root@openwrt
mtd -r write extracted_firmware.bin firmware
```
After the upload the router reboots itself and after this point,
**upgrading** should be always the preferred option to this one, because it
is not touching the bootloader.
