Olá, Já executei exatamente tudo aquilo que me indicado e nada, o Rádio não liga, o monitor nunca acende nem há qualquer sinal sonoro como fez logo de inicio. A fonte que ligo tem 13.5V e quando carrego no botão ON/Off do rádio no consumo é de 0.08Ah e um segundo depois passa a 0.007Ah e não liga. Esta fonte é a que uso noutros Rádios e está perfeitamente equilibrada e estabilizada. Estou desolado, que faço?

Hi, I am trying to update the rt73 radio firmware, and everything works fine with IAP (with message "IAP Checksum right"), then the radio is turned off. But when I turn the radio on, it still has the old firmware, with no change. I am using the original cable, with PL2303 Profilic driver in Windows. I've tried different firmware versions, but every time when I turn the radio on, the firmware is still the old one. It does not change, does not update, it is stuck, not writing . In the past I've updated the radio firmware successfully. Can anyone help me? Best Regards, Jose Damico

I wrote you an e-mail regarding problems with my RT73. I thoroughly described the issues of difficulties with uploading the firmware, or in fact the lack of possibilities. USB cable purchased in your online store, drivers downloaded from there also and it is not possible to upload, and the radio does not work. Please answer me.

I tried this and I got IAP Checksum error. After repeated attempts it just fails at different blocks. Now my radio won't function at all.

Estou com o mesmo problema, mais descobri que me enviaram o cabo com o chip FTDI, e o cabo tem que ser com o chip Prolific, existe alguma maneira de atualizar o firmware com este cabo ou eu tenho que comorar outro cabo, meu rádio também não liga mais, só consigo entrar no modo de firmware, tela branca. Mas o IAP trava a atualização sempre em uma pagina diferente.

This is down to digital signing issues and is 100% safe. You can ignore it directly and put it in your computer white list.
