Re: Help unbricking AC750
Hi! W dniu 2022-06-18 o 17:14, Luca Bertoncello pisze: Hi! I have an TP-Link AC750 Archer C2. It worked with TP-Link Firmware and I wanted to install OpenWRT. Unfortunately, something went really wrong and now the devices seems to be bricked... Only Power-LED is on, no other activity. Has someone an idea how can I try to recover it? If that's C2v1 and you attempted flashing it over TFTP without appending U-boot to the factory image first, then you might need to desolder the SPI flash chip and use an external programmer, for example one based on CH341 and reflash it externally with "flashrom" or similar tool. I recovered one unit that way, and found OpenWrt uImage where U-boot should have been.

The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software.--- Begin Message --- You can connect a serial interface to try a command line reflash if the uboot is still operational or as I see a winbond flash on the pictures it mean you can reflash it with a CH341 board the original firmware (exemple https://amzn.eu/d/5IDoawl). I don’t know if you are use to that kind of recovery but your U-Boot looks broken. > Le 18 juin 2022 à 18:02, Luca Bertoncello a écrit : > > Am 18.06.2022 um 17:55 schrieb Brice GIBOUDEAU: >> Try the recovery procedure detailed on the device page.
