Hi all, I got 2 Xiaomi Gigabit Edition routers and tried to flash them. After the ffirst bricked, tried many times to debrick with various methods and many images but all was unsuccesful. I think I havn't found the correct firmware for it.
At the second I tried with the other router but I havn't flashed yet but read the 'uname' and 'lsmod' information from it (using acecilia/OpenWRTInvasion guidance) and saw the following:
# uname -a
Linux XiaoQiang 3.10.14 #1 MiWiFi-R4A-3.0.27 SMP Mon Apr 12 09:07:54 UTC 2021 mips GNU/Linux
# the "/api/xqsystem/check_rom_update" output
{"needUpdate":0,"code":0,"status":
{"status":0,"percent":0},"changeLog":"","version":"3.0.27"}
Has anybody an idea how to debrick it and flash and install openwrt or it is impossible to this version.
Hi, thanks your link. But I can use acecilia/OpenWRTInvasion's method and can connect to the router via ssh or telnet. And of course can write to the MTD unfortunately :). Will call the Xiaomi service asking for correct test.bin, maybe it helps.
Sorry for misunderstading but I used acecilia/OpenWRTInvasion tool only on an untouched factory router and read system info via ssh.
I tried on another Xiaomi router previously which has bricked and hasn't debricked since. Tried many methods to debrick it, it works, asks the test.bin via tftp but all the downloadable firmwares are wrong so far.
If I understand well, it can't debrick normal way pressing reset button and powering on way? As far as I see the tftp works just firmware is not correct, see the following log line:
"dnsmasq-tftp: sent /tftpboot/test.bin to 192.168.31.11"
And the led light blinking purple very fast and nothing else happened. The router kept in bricked state.
I asked the official Xiaomi service helpdesk for correct firmware but they didn't help me unfortunately.
Thanks for advice, I don't have needed equipments for trying serial console access. I tried to examine the still working router and saw the following (accessing it via OpenWRTInvasion)
Very interesting, it contains a file named openwrt_release
Thanks for your linked files, I tried them but it wasn't successful to debrick the router unfortunately. After it I opened the case of the router and made a photo. Please take a look at the picture, it seems for me it is an Eon chip on the board.
Have you any instructions how to connect to the router via serial console? But I am afraid of that it is a newer model which hasn' got support from xiaomi yet.
Thanks for the link, I donwloaded it, will try. Would you send me a bootloader image also to try to debrick it via tftp? Does it work with dnsmasq also or needed to use miwifirepair tool? (the second method needed Windows and I don't have it)
Thanks, will try flash wwith your images sent before. May it use without debrick via tftp? Or needed to revert the original working operating system then flash it with yours?
