To great unfortunately, the other two routers GL-MT300A cannot be revived with the same method.
The firmware is loaded, the update process reaches 100%.
But more nothing happens, the update window does not closed.
In the beginning, I used the openwrt-gl-mt300a-clean-2.264.bin firmware, which previously worked fine on all three GL-MT300A.
Then I tried to use the new firmware gl-mt300a-3.0-1011_clean.bin. But this also did not give good results.
But after trying to revive routers are still unavailable at address 192.168.8.1 (also 192.168.1.1).
As a result, out of three routers, only one works.
And what do I need to do now?
