-==== Web Interface ====+Note that the time for an initial flash is very long for these devices. Users should expect 20 minutes before being able to access it, V4 can be 10 minutes, V1 is slower. Further sysupgrades may be a little faster at around 8 minutes.

 +</WRAP> 
 + 
 +It is possible to install OpenWrt via the TP-Link web interface, but you need to prepare the image first. 
 + 
 +=== Automatic image preparation === 
 + 
 +The [[https://www.aboehler.at/doku/doku.php/projects:re200|GUI tool (openwrt-imagetool)]] for creating a web-flashable image based on an original TP-Link firmware image and an OpenWrt image is available [[https://www.aboehler.at/hg/openwrt-imagetool/archive/tip.tar.bz2 | in this mercurial repo]]. Follow the instructions there or in the software. The software basically automates the below steps. 
 + 
 +=== Manual image preparation === 
 + 
 +You need an original firmware, the -factory.bin image as well as a tool to fix the image checksum. The below steps worked for me (**Warning: The firmware upgrade overwrites the boot loader and there is no recovery mode present!**):

You can use ''%%mktplinkfw -i stock_upgrade.bin%%'' to find out the correct MD5 sum and a hex editor to change the bytes of the header sum. The web interface now happily accepts the image.
  
-==== Serial ====+==== Web Interface Method (v2, v3, v4) ==== 
 + 
 +Simply install the -factory.bin image via the stock web interface. This procedure does not overwrite U-Boot, hence you have higher chances of being able to recover from a bad flash. (note: for v3 running TP-Link firmware > 1.1.0, Web UI rejects OpenWrt factory bin. You need to [[https://forum.openwrt.org/t/tp-link-re200-v3-refuses-to-install-openwrt/108388/8?u=ivzhh|downgrade to 1.1.0 first]]. The TP-Link US website doesn't have the 1.1.0 firmware link, you need to stay on the EU site and download the 2019 version) 
 + 
 +==== Serial (v1 and v2) ==== 
 + 
 +You need to configure a TFTP server at 192.168.0.10 and PUT the -factory.bin image as "test.bin". Then, interrupt the boot loader by pressing '2', accept the defaults and OpenWrt will be installed to flash. RE200 will look for test.bin at 192.168.0.10 having its own IP set as 192.168.0.254. 
 + 
 +==== Serial (v4) ==== 
 + 
 +You need to configure a TFTP server at 192.168.0.184 and PUT the -factory.bin image as "test.bin". Then, interrupt the boot loader by pressing '2', accept the defaults and OpenWrt will be installed to flash. RE200 will look for test.bin at 192.168.0.184 having its own IP set as 192.168.0.254.

 + 
 +<code>scp -O re200v1_tftp.bin root@192.168.1.1:/tmp</code> 
 + 
 +Install it by forcing a ''%%sysupgrade%%'': 
 + 
 +<code>sysupgrade -F -n /tmp/re200v1_tftp.bin</code> 
 + 
 +Flashing this relatively big file takes some time, so be patient. Afterwards, you should be back to stock. 
 + 
 +<WRAP round important> 
 +**If you flash the wrong file or mess up the preparation, you will have to disassemble your device and attach serial console!** 
 +</WRAP> 
 + 
 +As an alternative, you can use serial console: Put the resulting re200v1_tftp.bin image as "test.bin" to your TFTP server. Install via Serial as you would install OpenWrt. 
 + 
 +==== Back to Stock (v2, v3, v4) ==== 
 + 
 +Download an OEM firmware from TP-Link and prepare it using the tool ''%%tplink-safeloader%%'' from the OpenWrt development environment (should be included in the Image Builder): 
 + 
 +<code>build_dir/host/firmware-utils/bin/tplink-safeloader -z oem-firmware.bin -o oem-sysupgrade.bin</code> 
 + 
 +Transfer the resulting file to /tmp on the device, then run ''%%sysupgrade /tmp/sysupgrade.bin -F%%'' on the device. ''%%-F%%'' is necessary because the firmware does not have the upgrade metadata appended. 
 + 
 +**Attention:** After the first reboot, it is advisable to flash an OEM firmware upgrade. Otherwise, the software version is displayed as 0.0.0. 
 + 
 +**Note:** RE200v4 OEM firmware requires a ''%%soft_ver%%'' HIGHER than its own. This means (for the time being until a solution is found): 
 + 
 +If you 
 + 
 +  - Upgrade from stock to OpenWrt or 
 +  - Upgrade stock to newer stock version 
 + 
 +it will require the firmware image to contain a later firmware version than the one currently installed. However, if OpenWrt is always $STOCK+1, you cannot simply flash OpenWrt and revert to stock. Doing so would leave you with the OpenWrt-supplied FW version stored in the soft-version partition. Stock will then refuse any FW with a version lower or equal to this; which simply might not exist. 
 + 
 +This also makes the following impossible: 
 + 
 +  - flash OpenWrt 
 +  - revert to stock 
 +  - flash OpenWrt again (fails because the firmware already has the version used by this image) 
 + 
 +If the obove mentioned serial recovery should fail because of this, one could do the following: 
 +  - place openwrt-ramips-mt76x8-tplink_re200-v4-initramfs-kernel.bin as test.bin at the tftp server (if you compile that target it will drop in bin/targets along with the other images) 
 +  - press 4 to enter console mode (write help for available commands) 
 +  - tftp to load image into ram 
 +  - bootm to start the kernel 
 +  - you now have a running openwrt kernel and may bring a working image to /tmp (wget) 
 +  - sysupgrade with your image 
 + 
 +This however will not overwrite ''%%soft_ver%%''!
