Hello there!

I have followed this post https://community.tp-link.com/en/home/forum/topic/261318?page=16 and applied the beta firmware which brought the mesh support.

I would like to downgrade the firmware from beta to last stable version. I have asked the same in the original thread https://community.tp-link.com/en/home/forum/topic/261318?page=16 but I thought it would be worth to ask as a separate post to get assistance.

Any further help would be greatly appreciated. Thank you.

This is what I have tried already:

1. Initially running latest stable version
2. Applied the beta firmware ax11000v1-up-ver1-2-0-P8[20210415-rel78917]_beta_2021-04-16_10.34.39 and had issues with Wi-FI
3. Applied the second beta firmware ax11000v1-up-ver1-2-0-P1[20210512-rel61683]_nosign_2021-05-13_08.26.02 and Wi-Fi issues persist
4. Downloaded last stable version and tried to upgrade and its failed without any progress (error message: upgrade failed)
5. Reset the device (From the router website) to factory default settings and it still running on the beta firmware
6. Reset the device by pressing the reset pin and it still running on the beta firmware
7. Reset the device by pressing the reset pin and applied backup configuration file (I have taken configuration backup when the router was in last stable version)
