ER605 V2 firmwware upgrade fails applying ER605(UN)_V2_2.3.3 Build 20251029
I have model ER605 v2.0 devices running 2.3.1 Build 20251015 Rel.78291.
The latest firmware is ER605(UN)_V2_2.3.3 Build 20251029 which can be found at https://support.omadanetworks.com/us/download/firmware/er605/v2/
When the firmware update is extracted, the file is 24,753,017 bytes with this signature:
$ openssl dgst -sha256 "ER605_un_2.3.3_20251029-rel18054_common_v2_up_2025-10-28_14.25.44.bin"
SHA2-256(ER605_un_2.3.3_20251029-rel18054_common_v2_up_2025-10-28_14.25.44.bin)= c14392daa7e44bf01321da055f429c2da74bd1a4316b3e3c2efa85d746a52287
In the web GUI when I navigate to System Tools > Management and select the file above and click the Update button, I first get the message "Firmware upgrading…
DO NOT operate the device during this process." and then the error "Upgrade Failed. Please check the upgrade file and try again."
Please advise.
Thanks!
