I suspect that the SD card is corrupted when firmware was being written to the ASIAIR from the ASIAIR app in your tablet. Quite likely caused by a poor WiFi connection.
If the SD card is indeed corrupted, you will need to restore the SD card image that you had backed up when you had originally followed the "First Use" instructions in the ASIAIR User's manual. Either restore the image into the currently corrupted card, or restore the image to a new 32 GB SD card. It takes just 15 minutes to half an hour, and you should be able to see the ASIAIR WiFi access point again.
This time, make sure that you boot the ASIAIR from a solid power source, and have a solid WiFi connection (no more than a meter or two between ASIAIR and the tablet) when the old firmware is again updated from the ASIAIR app.
If for some reason, you had not backed up the SD card (which has a copy of the license file that is specific to your ASIAIR processor), you will need to contact ZWO (it is the weekend there, so you may need to wait another day or two).
Do you have another SD card you can try with? Anything with capacity of 32 GB or more will work (albeit, the max image storage area remains at 25 GB). In a pinch, I have used 64 GB cards.
This error occurred by the SD Card Reader IO error. Please try another SD Card Reader.
Please try to change to another SD Card Reader, we met this issue cause the reader IO error. Maybe this helps.Kurt wrote: ↑Tue Nov 05, 2019 12:42 amOn the first attempt to load the backup file, was with the original SD card (formatted) that came with the air, I attempted several times, with the same result, 83%. ZWO sent me a new OS, and I tried loading that on a new card It went to 96%, then stopped and gave same error message.
Do you have access to a different computer, especially a Mac that can run ApplePi-Baker? ApplePi-Baker seems to work pretty consistently for me.
Short of that, or if they still fail at 83% to 96% of completion, you could try these two things:
1) In case there are some partitions that cannot be overwritten, go to the SD Association web site and download and run their SDFormatter program to low-level format the SD card.
If memory serves, the ZWO SD card image has four partitions, a BOOT partition in FAT32 format, a Linux swap partition and a couple of Linux data partitions (ext format).
The part that bothers me is that you can't even write to a brand new 32 GB card, so a bad partition would not apply. Be sure to use the specific Samsung card that ZWO specifies; there are apparently some cards that are too small (possibly bad sectors) to take the ZWO SD image. But since nothing else seems to work, it is worth a low level format of the original (or identical) Samsung card.
Next thing to try:
2) launch whatever Windows program that you are using with "Run as Administrator."
Good luck again,
