2Q0 radar firmware downgrade
Hi All,
I would like to ask if there is possible to downgrade 2Q0 radar from version 396 to previous 383? I heard somewhere that downgrade is not possible and I do not want to corrupt firmware. Thanks, David |

RE: 2Q0 radar firmware downgrade
Thank you for reply, do you think that bootloader and X firmware is needed firstly before flashing normal 383?

I was firstly on X383 (done that with bootloader), then on normal 383 and then after few months directly to 396 but I was not doing anything with bootloader. |

Only H03/H04 can be downflashed safely. H10 and above will (soft)-brick during downgrade. But after flash 0396 again they will work again without any problems
