Please check the formatting of your card. Try either Fat32 or Exfat.
Someone asked if the measurements for the AMP2 are per channel. Yes it is for each channel. The AMP2 is very dynamic and clean and with a black background.
Hi Paul,
Finally I'm able to update the firmware, with generous help from another headfi member tkteo (thanks a lot!).
After that I retry myself and managed to update again, the root cause of previous failure should be due to I didn't manage to download a good/complete zip file from iBasso website, anyway just to share below the final steps i did and successful updated for other ppl reference:
1) Download the firmware from iBasso official site
(a) Better do not use any 3rd party download manager software but use the browser direct download
(b) Ensure the download is completed, check the file size
2) Unzip the downloaded file - for 1 times only
(a) This is the difference of my experience between failed to update and successful to update
(b) If you are unable to unzip the file using windows default unzip or 7-zip, then no need to proceed already, it means the downloaded file has problem. I tried to download at least 4 times and all failed to unzip, which led to failure to update software eventually.
(c) If able to unzip, then can proceed, you will see a folder, inside have a readme.txt and another zipped file (file name ending with ota.zip), this zipped file no need to unzip, leave it there.
3) Copy the ota.zip zipped file to SD card root folder (means not in any folder)
(a) Make sure the SD card was formatted in FAT32 or exFAT before you copy.
(b) On DX200, go to setting -> About DX200 -> System updates -> Local update -> locate the ota.zip then click update, the update will start if verified successful (i kept failing here yesterday).
(c) if the update started, remember do not power off or interrupt the update until it reboot automatically and completed.
I'm enjoying the DX200 now
