I've got a Memup DRW1004IM with RCP1-051 firmware. I've seen that ther is a BTC0151 firmware available.
As I know, the memup DRW1004IM is an OEM BTC 1004IM. But I can't use the new firmware. When a try to use the 0151 after changing the IdString, I can click the update button, but I get a "wrong firmware version".
Any solution ?
