Need Old Firmware for JODU51741 Device

Hi everyone,

I’m looking for the firmware for an older device with the model number JODU51741. I’ve searched online but haven’t been able to find any reliable source.

If anyone has:

The firmware file

A backup or dump

Or even a working link / archive

it would really help.

Additional details:

Device condition: (updated and locked ui)

I’d appreciate any guidance, suggestions, or alternative solutions as well.

Thanks in advance!
