How to determine if the radio has the 16Mbytes SPI-Flash or not ?

HI to Everyone,

we are facing big troubles in patching the TYT MD-380 (neither Tytera, nor Retevis. TYT only).

The patched firmware is running well, both on our Tytera MD-380 and Retevis RT3 handhelds. While doesn't work on TYT branded MD-380.

We know that it only works on radios with 16Mbytes SPI-Flash.

So here's the question: "Is there a way to determine if my radio has the 16Mbytes SPI-Flash or not ?

I'm looking for this kind of information everywhere, but no infos at all up today.

Is there any chace to solve this matter ?

Thank you in advance for any tip
