AnyTone AT-D878UVII PLUS CPS & firmware 4.00
Recommended version Not hosted — available from the manufacturer
Latest release: firmware and CPS 4.00. Removes the satellite function (not enough CPU space; the code optimisation it needed caused freezes on 3.08N) while keeping every other change since 3.04, and fixes APRS settings not downloading in the CPS.
Read before installing. Not hosted: every AnyTone/BridgeCom package includes the 'D878UVscreens' background-image set by Tim Rauhut, DL2DMC, whose readme says it 'must not be re-distributed without written permission of the author', and vendor files are never modified. Package D878UVII PLUS V4.00 official release 250815.zip: 27,573,577 bytes, SHA-256 5ba14d88cebef105365e8977529a5817d1d163a9e9eccc5156ccd9575be500e6 (checked 2026-09-18). Contents: CPS installer (D878UVII CPS 4.00), firmware D878UVII_V4.00_20250725 (.CDD/.CDI/.spi), update instructions and change log (PDF). Install: CPS > Set > Set Com; turn GPS and APRS off in the radio; hold PTT + PF3 (top key) while powering on (red LED blinks); CPS > Tool > Firmware and Icon Update > Open Update File > the .spi in the FW folder > Write; then reset the MCU by holding PTT + PF1 while powering on and confirm 'Initialize'. Save the codeplug first: the reset erases it. Use D878UVII_* firmware only; D878UV (V1) firmware gives 'version error'. The CPS version must match the firmware version. A byte-identical CPS and firmware (repackaged zip) is also on anytone.net/download-list-5.
