i found this device on the market as Mobile Router with Global coverage - supported frequencies covers worldwide networks LTE and 5G… this is based on platform MediaTek Dimensity 7300 - MT6878. Original software is based on Android 14. Working quite well. But as this is Android usage is limited.
Device have sim slot, esim support and Wifi Extender that allow connect me to hotel wifi, run OpenVPN and provide network access via hotspot behind this vpn, unfortunatley Wireguard is not supported.
Device parameters are quite powerfll with 4GB RAM and 8GB storage. (full spec in manual)
I was thinking if there is possibility to use this device with OpenWrt?
I was googling and found this:
and this:
In my opinion this can be very interesting device running opewnrt.
Without looking deeper into the specs, there are enough keywords to suggest that the device is more of an android smartphone without display, than a traditional router with a dedicated modem. Getting that supported on OpenWrt would be very hard (and very unlikely).
I was able to enter debug mode, bootloader loks unlocked:
fastboot flashing unlock OKAY [ 5.080s] Finished. Total time: 5.080s
but when i was searching for “OEM unlocking” this this option is greyed out and looks like is “off” but there is info “Bootloader is already unlocked” but checking flag from fastboot shows:
fastboot flashing get_unlock_ability
(bootloader) unlock_ability is false
So i don’t know if bootloader is unlocked or not…
Im able to connect via adb and have shell, i can boot in bootloader mode, recovery mode looks like doesn’t exist.
I tried with mtkclient but it looks like this platform is not supported.
Device is unlocked, i was able to download all partitions - firmware data. This is Android 14. I was able to patch init_boot.img with Magisk and get root. Now i have fully working router on Android with full ssh/adb access to this device and this is great. Im was able to install wireguard in parrarel to openvpn - works!
As i know that device is unlocked, imble to flash partition’s im thinking if we are not step closer to possibility of porting OpenWrt.
As i meintoined on previous post - there is linux distribution for SoC - MT6878 - postmarket OS.
I just purchased this device as well. How did you get into fastboot?
I noticed you can get into the Android system UI by tapping on the serial number rapidly, which opens a debugging app with the system UI accessible at the top. This also allows you to enable adb access for your host.
