@Dear Henry,
If you purchased the item from Cudy’s official flagship store on Taobao or JD.com, you can contact customer service directly to request a replacement.
“Hi support.
1. Guys I think a comment of a blog entry is not the better way to provide tech support.
2. So I downloaded this one:
m_upgrade_TR3000-R47-2.4.21-20251009-140812-sysupgrade_90649
Both routers download the bin file and after install the router led flashes to red and stay like that. Is there something else I can do? I’m in mainland China, is it possible to give this two devices back to the factory?
Both of your router are 128MB Flash version according to the SN. So you must download the firmware for TR3000 V1.0 to recover the router. Not the firmware for TR3000 256MB Flash V1.0
“Hi support team! According to your question “please check the SN number on the label at the bottom”, so two of my devises are:
tr3000245000505 EU1.0
tr3000250202816 ZH1.0”"

@Уважаемый Александр,
Какую прошивку вы использовали для восстановления маршрутизатора? Пожалуйста, пришлите мне название прошивки, которую вы скачали.
Кроме того, разжимали ли вы прошивку в файл с расширением «.bin» перед тем, как переименовать его?
“Здравствуйте, роутер TR3000, делаю откат с OpenWRT на прошивку cudy по инструкции, в программе показано что прошивка загрузилась, на роутере мигает индикатор с красного на белый, больше ничего не происходит, что делать?”
