Hi sirs,
My unit is uSpirit on my OXY2 with 4649T & hobbywing esc. It flys great when I use 2.7.1.
I just update to 3.0 about 5 days ago, and I found that the website suggesting downgrade to 2.8.
So I install 2.8 windows software and try to flash 2.8.0.4 firmware which is also downloaded at website.
When I try to flash 2.8.0.4 firmware, PC software tells me to flash 1.3.2.4 firmware, so I followed.
After 1.3.2.4 flashed, I continue to flash 2.8.0.4 and go the setup wizard flow. I select uSpirit in setup wizard but the pc software tells me that the unit is Spirit ? but it says that's fine ? So I keep setting and found that my swashplate & tail compensation is all gone !!?? What ever I re-connect the battery or re-flash 2.8.0.4, the uSpirit looks init fine but without any compensation. Could you please help me ? Thank you.
Best Regards,
Pu-Sheng

Update status when I try to flash my uSpirit Back to 3.0.
In setup wizard it shows my unit is Spirt, but actually it's uSpirit.
An I got an error message here.

Hello,

the problem was not update, but something happened to the internal data of your unit.

It can be fixed easily. We will send you firmware that can fix your unit. Then it will work again with any version.
