Can the Flash_Dump/MX25L12835F_CFW_20210830_V4.bin be used on V4 device?

Hi @ludwig-v stupid question, can the Flash_Dump/MX25L12835F_CFW_20210830_V4.bin be use on V4 device?
As far I understood it last version of the FW you were able to repack.
Do we need to care about any HW differences between V3 and V4?
I wanted to use the device as AAWireles gateway - just compiled old public version of the project and tried to run it on Pi Zero 2 W2, but the performance is not satisfying.

I was just wondering if maybe there is an other way to dump file system - maybe some boa server vulnerability.
