Before You start to read: I'm doing it because I want to - I will not be very sad if I brick it. I just want to learn something new about making firmware, and I believe it is my occasion.
So I got this model for free.
When I was looking for some information about, Google redirects me to W8960. Although it seems to be completely different hardware I've found the RS-Header information useful.
Here is boot log:

TL-WA701N login: But, wait! TL-WA701N? I went to OWRT Wiki, and there is short description about this one:
Similar to the TP-Link TL-WR741ND but with PoE and a smaller antenna.
Further reading provides that CPU of Version 1 (other CPU's on v2 and v2.3) is Atheros AR7240 (same as here?) and that on version 1 OpenWRT 12.09 Does work [AA12.09: openwrt-ar71xx-generic-tl-wa701n-v1]
Lets look at TL-WR741ND.
Version 1.x looks by design quite simmilar and up to 3.1 by hardware.
What should i do next? Should i try to install AA12.09: openwrt-ar71xx-generic-tl-wa701n-v1?
