Hi Hayabusa,

1 - Rescue button
2 - Connect board

What appends ?

[Hayabusa1]

Hello,

yes when i do Rescue he connect and then when i try too update it dont does anything, and what i noticed, when the board is plugged in i always here a sound same a usb device is alwas plugged in and then plugged of again and again, when i look in the device manager the computer sees the board as a Hid device! there must be something wrong, maybe there old data from the taulabs on it...

when i try with the taulabs gcs  the flashing works right!!

Try to update bootloader first.

Download bootloader from here :
https://librepilot.atlassian.net/wiki/download/attachments/4128780/bu_revolution.opfw

Take a look here :
https://librepilot.atlassian.net/wiki/display/LPDOC/Firmware+Tab

1 - click Rescue
2 - connect board
3 - Open and select the BootloaderUpdater (BU) file from where you saved it on your hard drive
4 - flash button is now enabled : Click Flash to flash it to your board,
5 - After flashing complete, press Boot and wait until the blue LED is on, then flashes, and finally goes off (normally ±15 seconds).
Wait 10 seconds more.
6 - Disconnect the board from USB.

i try i can go too step 6, and not more, the bootloader i can Flash no Problem, then i click boot when it is ready and i reconnect the board, then it dont comes back, i must do rescue again and when i try ugrade and erase he dont do anything hmm

do you have a revo board? maybe you can upload the Firmware file from your board and i can flash the file manualy

[f5soh]

Try manual erase :

Rescue
Erase settings.

Second option, flash firmware attached :

Rescue
load
flash
boot

wait some time

If it has a TauLabs bootoader, you will have to do the SBL and do some special commands.

Do you have an LP build environment?  That is the easiest way.

What OS are you on?  Windows?

See if you can acquire the program "dfu-util"

See this post that I wrote up about flashing a bootloader.

See the first post in this thread if you have a Revo or Sparky2 that is bricked and won't run (blue LED has a 7 second blink over and over).

Thank you very much!
This fixed my cc3d Mini Revolution reboot loop, after having Taulabs on it.

Well I have this very pproblem with Revo mini
I made several times everything discribed here without any success
Blue led shows bootloader mode and it stays in this position.It seems that bootloader upgrade is somehow faulty
I didnt find any marks for SBL
So,has Revo mini board it at all?
Please advise ,what next?

[f5soh]

Revo Mini do not have SBL pads, to enter into bootloader mode and do dfu rescue you need to solder a small wire by yourself.
