I'm in China and have a Chinese version of the Archer C7 AC1750 (TL-WDR7400) v2 onto which I want to install LEDE. However, when I try to flash from the stock TP-Link interface, it says "发送请求失败,请重试" which indicates failure. I've tried several varieties of firmware, including OpenWRT and the "optimized" version of LEDE from github/infinitnet; they all give the same error.
I understand the stock TP-Link does some region checking on firmware uploads, which is perhaps what's causing it to reject uploads? Does anyone have any suggestions about how to proceed? Thanks!
Thanks for replying! This router has never been upgraded; it's running the factory default. I looked for a while but my Chinese isn't good enough to find the firmware downloads page on tp-link.com.cn - is that what you want to find, a link to download the TP-Link stock firmware?
Based on Wiki, TL-WDR7400 v2 doesn't share Archer C7 v2 US/EU hardware design, it looks more like the C7 v4. Don't try to flash it with a wrong firmware.
Interesting, thanks. I wonder if all the Chinese versions of Archer routers are so different from EU/US versions? I also have a Chinese AC-1300 (TL-WDR6500) v6.
