I had the same problem “ERROR!! ACK is not found”. Unfortunately, doing the factory reset on MacOSX and installing the standalone mixer firmware did not fix my VCI. It’s still stuck in bootloader mode! Can you explain more clearly how you were able to do the DJTT v2 update at the end of the standalone mixer update?

I had the same problem as I posted in the Mapping Downloads area.

I followed FlashFlooder’s Advice and persevered with it and finally got it to work.

For me the way I fixed it was the following

  1. Powered off my VCI400 and left it powered down for a few minutes.
  2. Restarted my PC.
  3. Connected my VCI400 via the USB Cable - But did not power it up.
  4. Opened the FirmUP.exe and left it open.
  5. Started the VCI400 in Bootloader Mode
  6. Tried to flash and in this case it was successful.

Hopefully that helps.

Okay, after hours of trying different scenarios this is what finally worked for me:

  1. Restart PC
  2. Turn VCI-400 on in bootloader mode
  3. Open FirmUp and attempt update
  4. Update fails and gives the ACK error
  5. Leave Firmup open
  6. Turn off VCI-400 and turn it back on in bootloader mode
  7. Without changing the previous Firmup settings, press Start again.
    Wow what a pain!

F…ck non of this works in my case. I can do what I want… it always says:

When I press “get Version”: there is no reply
When I press “Start”: ERROR ACK is not found

On fifth time of reboot (when i started to panic) this works!
Many thanks!!!

p.s. “Dj techtools guys”, you REALLY need to do something with this flashing process…

i cannot get it to bloody work… close to taking a hammer to the f**king thing!!!

Please Help! Just got my VCI400EG When I plug it into
my mac and open the Vestax updater, it says

Device :VCI-400
Audio Firmware : vFF.FF ???
MIDI Firmware : v07.02

Is this even correct? Feels like I may have updated or changed the wrong file :disappointed:

If anyone can help me. I’d really appreciate it

What manufacturer laptop are you using?

You still having problems?

I hope the other user replies, for I am having a similar problem–although may/may not be the exact issue.

My VCI 400 unit is not stuck in boot loader mode. It is unable to get into boot loader mode. The reason this all happened is, I attempted to upgrade to the recent Vestax 2x firmware, and it seemed to cause a conflict with the existing firmware. So now, I’m attempting to restore to factory settings, yet, I cannot get into boot loader mode in order to do this. I have contacted Vestax, DJTT, and Flashflooder, and await a response. If I find out a solution, I’ll be sure to follow up to this thread.

When I press “get Version”: there is no reply
When I press “Start”: ERROR ACK is not found

Quickswitch.. What manufacturer laptop are you using?

My hardware conditions occurred with Mac OS, and (Toshiba) Win 7, and Win 8, using Traktor 2.6, with Flashflooder 2.5.1 mapping.

I thought I’d share what I experienced with other users… The reason I think I was unable to get into boot loader mode (instead of being locked within boot loader mode), was because the USB/Power lights did not behave as they normally would–indicating the boot mode is enabled.

After going through many re/installation procedures, I eventually got to a clean reinstall (including the Flashflooder goods). Yet I was only certain on a few attempts, if ‘boot loader mode’ was in fact enabled, because the of lights.

I later experienced what being locked in boot loader mode was, but I quickly recovered from it. So… there’s 2 different problematic scenarios.

On other reinstall attempts, the firmware updater app would message, ‘no reply’, which also did not indicate ‘boot loader mode’ was actually on/off.

I researched through others’ related issues. I didn’t read a mention of the scenario, I’ve just described. I hope this information makes sense and helps. If I can help more, let me know. For now, I’m staying clear of any future firmware updates until further notice, or unless those updates come from Flashflooder.

For the record, I did not need to downgrade to the FW1 flashflooder ware, nor do a factory reset.

Back to normal operations.
