Would it be possible to post the source you compiled the binary from to post on GitHub?
Or how were you possible to create the firmware?
Thank you!

@dhmyess amazing work, thanks for sharing.
I installed openwrt-ar71xx-generic-cpe220-v3-squashfs-factory.bin and so far so good, however when I try to install openwrt-ar71xx-generic-cpe220-v3-squashfs-sysupgrade.bin I got a warning message stating that the file does not contain a supported image 
Moreover, when I choose to force installation to check image's information this is what I get:
The image seems to be downloaded correctly, with a file size of 7.803.649 bytes.
Any idea?
Edit: ok, I didn't see that I had to select the sysupgrade image once again after checking force installation 
Can you confirm this information is correct?

Hi,
sorry for the bad news but ar71xx is deprecated and will be replaced by ath79 soon. ar71xx is already made source-only in master.
If you would like to add it as a supported device for the future please port your changes to the ath79 target.
Then you can send a git pull request to https://github.com/openwrt/openwrt/pulls
Best regards
Sven
Not Correct, it should be

cccbeeb563506eaa598841acb14aa794c99e505c4a0714529f54695cb84e5c04 *openwrt-ar71xx-generic-cpe220-v3-squashfs-sysupgrade.bin
Hi Sven, Thank for your information.
Since these are snapshot builds, the sha or md5 is likely to change every day when it is rebuilt. You need to get the most recent one from the download page at the same time you download the file.
Thank you all for your replies.
Can you tell me where to download the newer images from? I couldn't find the snapshot releases in https://downloads.openwrt.org/ (the ones I previously downloaded are the ones you shared through GDrive)
The CPE220 v3 is still not officially supported, hence no downloads being available on the official download server.

Incidentally, I found this bug in the logs:
Mon Aug 19 20:14:21 2019 daemon.info uwsgi: /sbin/sysupgrade:
Mon Aug 19 20:14:21 2019 daemon.info uwsgi: /lib/upgrade/platform.sh:
Mon Aug 19 20:14:21 2019 daemon.info uwsgi: line 590:
Mon Aug 19 20:14:21 2019 daemon.info uwsgi: syntax error: unexpected ")" (expecting ";;")
Mon Aug 19 20:14:21 2019 daemon.info uwsgi:
I think the issue resides in line 586 containing cpe220-v3), which seems to be a leftover since it appears that you later moved that section of the case statement a few lines down:
cpe220-v3)
tplink_pharos_check_image "$1" "01000000" "$(tplink_pharos_v2_get_model_string
return 1
;;

Edit: Okey i was reading a bit about snapshots firmwares... as a noob on this matter as i am it would be better if i keep away of installing that files from google drive right?
