So far 7023b after updating it with 7010b Epdkv100 (accidentally downloaded and installed wrong update via sd card) received dead radio turning on showing welcome followed by black screen no buttons light, bought ch341a and did 3.3v mod and using bios pins 25xx series on ch341a managed to read chip via Neoprogrammer. However I am not able to find any working firmware, any firmware I could found here on elektroda does nothing apart from either full dead radio, lighten up black screen or only buttons light up.
It's a ZCD7106-C200S-MAIN V2.2G (dated 2024-10-25) main board with F1C200s processor (P6034BB 6732) and 25QH64DHIQ eeprom/bios chip (P4098800 01 2423Y),
button board is ZCD-RF701-KEY_v2.0 (dated 2022-11-14)
Any1 here has a working dump .BIN ?
AI: Can you post the exact sticker/label from the radio casing (brand/seller model, MCU/version, serial, screen size if shown) or at least a photo of it? 7023B alone is too generic and same PCB can use different panel/LCD variants.
ZCD7106-C200S-MAIN V2.2G
AI: Do you have a backup/readout from your original 25QH64 before writing anything else — and if yes, what exact size is the BIN and can you share it/check whether the read is consistent on multiple reads?
no
