Hi guys today before my training I decided to flash the newest soft for my FC tattoo 4FS.
Before I did it I have made backup of previous settings - diff all - see it attached below.
After flashing new soft I got some error messages - see attached screenshot seems new version changed names etc..
During try of lunching my drone it got crazy. It is laying on the ground yaw, roll and pitch seems to work ok but while I am putting a little throttle it got crazed with very high throttle peek and backlflip.
Props are installed correctly.

I have attached diff all and dump for new flashed soft 4.0.1.

Could you help with that issue?
thanks

You can't apply diff settings from a Betaflight 3.x (or earlier in fact) firmware install to a Betaflight 4.x firmware install.

The way Betaflight 4.x PIDs and filters are tuned is a lot different to Betaflight 3.x and if you try to restore pre Betaflight 4.x settings you risk a flyaway.

The best you can do is to restore the sections of the diff from Betaflight 3.x that are to do with Port config, Mode config, Beeper config, LED config, ODS config, and a few other things that have nothing to do with tuning. You can also use your previous rates.

If your Betaflight 3 x install was custom tuned (not the default stock Betaflight tune settings) then you will have to tune Betaflight 4.x from scratch again. There are some tuning notes HERE.

Two qustions.
1. Can I restore somehow 4.0 default settings and then set up my rates, modes, osd, beeper only?

2. If I have diff all. Can I flash older soft the one I had? in that case switch from 4.0.1 to 3.x and restore my diff all backup?

You can restore BF4.0.1 back to default settings by entering the "defaults" command into the CLI. Then copy and paste in individual setting sections from your Betaflight 3.x diff file but only the sections that are not for tuning. I can take a look at your Betaflight 3.x diff file a bit later and help you with that if you need it.

If you want to go back to Betaflight 3.2.5, then yes, you can just reflash that older version and reapply your diff file. It will then be back to how it was before.

Great so I will back for a moment to what I had. Not too much time at now to experiment and would like to fly tomorrow 
Then within a days I would really appreciate If could help me to set up for BF 4.

Thanks !

Shit I messed a little my previous soft was LUXF4OSD (LUX4) 3.2.5 Feb 11 2018 not Omnibus I guess I had a lot of luck not loosing my bird

EDITED:
Just came back to LUXF4OSD (LUX4) 3.2.5 Feb 11 2018 with my settings.

OK, so when you get around to re-flashing Betaflight 4.x again you can just copy and paste the following into the CLI and run it. This will apply all the settings that you had applied for Betaflight 3.2.5 except for any of the PID profile stuff. While some of the rate settings between Betaflight 3.2.5 and 4.x are the same, some of them are different so I think it's probably safer if after flashing and applying the below that you then go in and manually re-apply your preferred rates in the PID Tuning tab. Some of the setting names have changed between Betaflight 3.2.5 and 4.x but I've substituted any of those with the correct new setting name.

Great many thanks. I will use it for sure. Btw I used the occassion to refresh all motor joints as well as camera since I noticed wire isolation uncovered some of wires.

Again my sweet bird is adorable to me
