For users who install FancySS before January 1, 2022:

From January 1, 2022 onward, v2ray will drop support for the legacy Vmess+MD5 protocol and will not force users to switch to Vmess+AEAD ciphers.

The official FancySS repository is over 2 years old, and does not support Vmess+AEAD. Therefore, if you have installed this version before, your router will most likely stop working. If that is the case for you, then you need to update your v2ray app.

To fix this issue, you’ll need to update your Merlin OS to the latest version (Merlin Koolshare 380 X7.9.1), and install the Shadowsocks.tar.gz file from this GitHub repository (like you did when you first installed V2ray on your router).

380 firmware: https://fw.koolcenter.com/Koolshare_Merlin_Legacy_380/

Latest V2ray-core: https://github.com/cary-sas/v2ray_bin

If you are running a router that is incompatible with firmware 380, for example a router running firmware 384 or 386, you can install Merlin Clash instead: https://mcreadme.gitbook.io/mc/


We do NOT guarantee that our VPN will work with your specific router.

Each router is different. The same model may be flashed with a different version of the OS, and some routers may only support older OS versions which don't work with our App.

Please only purchase a router listed in this guide below.

We do NOT provide extensive customer support for routers.

We only support routers listed in this guide below.

We only provide support for configuration of the V2ray app:

  • Where to put the API link and how to update it.

  • How to setup DNS to prevent DNS poisoning.

  • How to connect to a specific server.

We do NOT provide ticket support for:

  • Flashing your router

  • Installing the V2ray app on the router

  • Exception: If links in this guide are no longer working, you can open a ticket with us to get working links.

However, we do provide this guide in English, as well as links to other resources you can read should you need more info.

Buying Your Router

The v2ray app for Merlin is part of the fancyss app package. It can only be run on a customized version of Merlin, Merlin-Koolshare.

Therefore, you'll need to get a router that can be flashed with Merlin-Koolshare (or that comes with it pre-installed).


  1. Purchase a router that can run Merlin-koolshare

  2. Flash it with Merlin-Koolshare

  3. Download and install the FancySS app package

Flashing your router

Once you've bought your router, you'll need to flash it with Merlin-Koolshare.


  1. Make sure you already have Merlin flashed on your device

  2. It is recommended to first update your Merlin firmware to the latest version from your router's manufacturer website or merlin's website before installing KoolShare.

Download the KoolShare firmware

Find which version of Fancyss your router supports from the router list above.

For Fancyss_hnd:

For Fancyss_arm384:


For Fancyss_arm:


For EA6200 router, download the latest 7.9.1 firmware here.

Flash your router with KoolShare

  1. Login to your Merlin router

  2. Go to Administration > Firmware upgrade

  3. Click on "Choose file"

  4. Find your downloaded firmware (ends in .trx) and click "Upload"

Enable JFFS

Next, we need to enable JFFS to be able to upload FancySS to our router.

  1. Go to Administration > System

  2. Enable "Enable JFFS partition", "Format JFFS partition at next boot", and "Enable JFFS custom scripts and configs"

  3. Click "Apply" at the bottom of the page

  4. Reboot your router

Install the APP (FancySS)

First, you need to download the correct version of FancySS for your router.

Go to the corresponding page below and download the latest version of the shadowsocks.tar.gz file.

The file will have a version number. You'll need to rename it to just shadowsocks.tar.gz

For Merlin Koolshare 380

For Merlin Koolshare 384/386

Use Merlin Clash instead:


Once downloaded, you have to rename the file to shadowsocks.tar.gz

Install Shadowsocks.tar.gz on your router

  1. Login to your router

  2. Go to "软件中心" on the left menu

  3. Click on the "离线安装" tab at the top (see picture)

  4. Click on "Choose File" and select the [shadowsocks.tar.gz] file you downloaded in step 1

  5. Click on "上传并安装"

If you get an error message saying that the package is not allowed to be installed, you need to remove the restriction.

  1. Enable SSH in Administration > System

  2. SSH into your router (you can use putty on windows, or terminal on Mac) and run the following command:

sed -i 's/\tdetect_package/\t# detect_package/g' /koolshare/scripts/ks_tat_install.sh

That is one line only.
