Hey there!
Today I purchased Mi 4a Gigabit International Edition (production date 05/2021) and tried to install OpenWrt with no success.
I immediately thought it was because of the new chip, but... strangly it's GigaDevice GD25Q128C
, which should be supported.
# dmesg | grep GD25
[ 0.430000] GD25Q128C(c8 40180000) (16384 Kbytes)
# dmesg | grep flash
[ 0.430000] flash manufacture id: c8, device id 40 18
The bootlog is almost identical to https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition#oem_bootlog
My flashing steps as follows:
- Exploit 4a with
OpenWRTInvasion
- Download firmware: https://downloads.openwrt.org/releases/21.02.3/targets/ramips/mt7621/openwrt-21.02.3-ramips-mt7621-xiaomi_mi-router-4a-gigabit-squashfs-sysupgrade.bin
- Put OpenWRT firmware with
ftp
to/tmp
. - Flash with
mtd -e OS1 -r write openwrt.bin OS1
After unlocking/flashing/rebooting, 4a just rarely blinks orange. Unbricking with TinyPXE4AINT
works fine.
Thanks in advance!
