[RT-AC3100] - Transmission error Install

[elrengo]

Hi! I bought a Asus RT-AC3100 router. Yesterday I installed the AsusWRT-Merlin Firmware (Stable Release: 380.58).

I have attached to router 2 HDD. First in USB3 a Sonny 1TB (USB3), second in USB2 a old laptop 500GB using a Kingstong enclosure.

In Sony I shared media to my Network, at this moment only fotos.
In other I create 2 filesystem, 1 GB Swap file system then EXT4 file system to install entware, transmission or other software and for the files download by torrent.

I follow the wiki to install entware and transmission:

1. https://github.com/RMerl/asuswrt-merlin/wiki/Entware
2. https://github.com/RMerl/asuswrt-merlin/wiki/Installing-Transmission-through-Entware

That was imposible to found how to enable swapon for swap file system I follow the step to create a swap file and enable it.
And I enable the "JFFS Partition" and "Enable JFFS custom scripts and configs" then formtat them after restart.

When I finish the intall and go to browser: 192.168.1.1:9091 I fown this error:

404: Not Found

Couldn't find Transmission's web interface files!

Users: to tell Transmission where to look, set the TRANSMISSION_WEB_HOME environment variable to the folder where the web interface's index.html is located.

Package Builders: to set a custom default at compile time, #define PACKAGE_DATA_DIR in libtransmission/platform.c or tweak tr_getClutchDir () by hand

Command result:
