We flash the electronic control unit M73, manufacturers Avtel and Itelma. M73 can be either with a closed bootloader (loader), i.e. with a locked processor, or with an open bootloader, i.e. with an unlocked processor. Each type of bootloader of the ECU M73 has its own nuances when reflashing. M73 Avtel/Itelma (with a closed bootloader) are flashed - by diagnostics. M73 Avtel/Itelma (with an open bootloader) - by diagnostics / in BSL mode. Some programs for reflashing M73 units: ST10Flasher, Combiloader, OpenBox, ChipLoader. Be careful, you can easily ruin your ECU M73 when reflashing it. group in vk http://vk.com/paulxenon I'm in vk http://vk.com/paulxenon1 Factory firmware for the M73 ECU in decompiled format, you can download it from my group http://vk.com/topic-55389136_31094401 Financial support for the channel: Webmoney R387271933832 Z362404111228 Yandex money 41001669548677 Qiwi 9539015181 Mastercard 5469430010205831
