Looking for TP-Link WDR3500 stock firmware

Dear all, for some migration testing from ar71xx to ath79 of a TP-Link WDR3500, I would like to temporarily revert to the stock firmware. However, I can't find it on manufacturer's page, and the link in the wiki (" * TL-WDR3500 V1 TL-WDR3500-V1-stripped.zip) is broken. (https://openwrt.org/toh/tp-link/tl-wdr3500_v1?s[]=wdr3500)

Does anyone still have the file somewhere?

Thanks

shouldn't need to go via stock fw to migrate from ar71xx -> ath79.

use sysupgrade image, reset settings during flash.

not if you have openwrt or Freifunk firmware installed already. However, going from stock to ath79 target is one of the integration test cases.

see https://github.com/freifunk-gluon/gluon/issues/2413

Ah, ok ...

https://www.tp-link.com/us/support/download/tl-wdr3500/#Firmware ?
or do you need the stripped one ... ?

Thanks for the link, I guess I can strip the firmware myself using the instructions from https://openwrt.org/toh/tp-link/tl-wdr3500_v1?s[]=wdr3500#factory_restore

In case, you or someone have the stripped version readily available, I would take it.
Thanks!
