The same WebUI freeze is happening here on my RUT955 Batch 087 after a hard reset attempt which didn't involve any bootloader/firmware upgrade. I can still do SSH login, also I noticed that the hostname changed to Teltonika-UNKNOW
This all happened on the latest RUT9 firmware, which was working fine before the reset button was held down.
After that, I loaded again the very bad legacy firmware, and loaded again the RUT9 firmware, but the situation didn't change. I'm still locked out from the WebUI.
Would you please:
1) Update the bootloader so that it would accept as valid the checksum of the latest RUT9 firmware
2) Provide a way to fix my device?
