How to roll-back AsiAir version?

Post by BB001 » Mon Feb 10, 2020 5:50 pm

Hi,

I’ve been testing v1.4.1 (9) and ran into a camera control issue. It can no longer read images from my Canon 60D. I tried to install 1.4.1 but the install knows the firmware is updated and halts. (The EOS untilty on my MAC reads the camera fine as previous AsiAir software also worked well)

How do I reset the firmware so I can go back to the production software version?

Thanks,
Bill

Start by restoring from the SD card image (.img format) that you had originally saved when you first bought the ASIAIR. Burn that image into a brand new 32 GB Samsung microSD card. Do NOT overwrite your current microSD card -- it may be your only lifeline to your license file. Without a license file that is keyed to your Raspberry Pi's processor number, you will need to email ZWO for a license file, and it might currently take longer to receive a response.

Remove the beta v1.4.1(9) app from your tablet.

Next install the released 1.4 normally from the App Store.

When the app runs, the released ASIAIR v1.4 app should then update your firmware to Firmware 4.55 instead of to Firmware 4.66 (assuming that is your problem).

If you are on iOS, you cannot roll back any further than v1.4. If you are on Android, look in your folders for the APK files from the earlier versions of the app that you had installed. Remove the current ASIAIR app and install from one of those APK files.

If you forgot to save the original SD image,

(1) mount your existing microSD card on your computer. It should open with a volume called "BOOT". In the BOOT volume, you will find a file called "zwoair_license". Copy that file to your computer. This is the file with an encrypted string that corresponds to your Raspberry Pi's processor ID (ZWO also uses part of the ID as a serial number of your ASIAIR). You should save this file in a safe place, and additionally write-protect this file on your computer for as long as you own the ASIAIR.

(2) download a generic ASIAIR SD image from the web (just Google for it). It will not include a license file

(3) Burn a new microSD card from the downloaded image (you can use ApplePi-Baker if you are using MacOS X). Do not burn it to your existing SD card (see warning in the first paragraph).

(4) Mount this new microSD card.

(5) copy the license file over to the mounted volume (BOOT) of the new microSD card. The microSD card is now ready to use.

Clear skies,
Chen

My backup disk loaded but the network would not start. I recreated the boot disc from scratch. Worked like a charm.

Moral to the story: Test backup images and in all things be patient.

This is back to not working.

As I wrote last night this all worked. Today i went to create a fresh backup and the create secondary backup disc; testing it I found again AsiAir reports for Canon the message “ Can’t stop immediately, please wait for seconds. So I went back and created a new boot disc; just like last night. That started the AsiAir and updated firmware to 4.66.

Going to test Canon (60D) again it failed. Sometimes it will trigger the shutter but not load, other times it immediately reports the above message. The camera works on EOS utility. I’ve also replace the USB cable to AsiAir. The 5G network is on. The camera is set to bulb, manual, raw etc.

I don’t get it. I just used this setup v1.4.1 from Apple for 2 weeks of shooting at end of January. It only broke when I got to 1.4.1 (9). This Apple distributed version should be working.

What’s going on?

Thanks,
Bill

Hello Bill,
There are no changes since the first support version of DSLRs, the message 'Can’t stop immediately, please wait for seconds' caused by the hardware api limition, so just wait.
