Damage after driving in 4H (4WD) with hand break engaged?

Good day, 
About half a year I own new Jimny 2021 (manual transmission) and today this icy winter day I used 4H.

I know I should never use hand break with 4H or 4L mode.

But after I return from my grocery store in parking lot I turn rear gear and drive about 2 meters back (4H was engaged), I instantly feel resistance and press clutch and take off car from hand break. Looks like everything is ok, and I think everything is working normally.

But I still scared If I made some damage and greatly reduce lifetime of my transfer box or maybe some other parts, what do you think about this situation? 

Im new to this type of cars.

Thank you in advanced:)

Who told you that you should never use the handbrake in 4H or 4L?

No, don't bother to tell me, it's what we call an "Old wives tale", so you can forget that bit of your story and rest easy.

As Lambert has said, no damage.

Probably of more concern is using 4H on-road. You should only engage 4wd when the surface offers a good amount of slip, otherwise the lack of a centre differential means you're at risk of stressing the drivetrain. Cold days with a risk of ice don't really meet the criteria.

Don't forget that 4wd only helps you go, it doesn't help you stop or steer.

I disagree with the comment "it doesn't help you ----or steer".
When I was teaching people the fundamentals of driving on a dirt surface, I would get them to drive down a wet grassy/dirt hill and try and turn at the bottom whilst in rear wheel drive. The motor would just go straight on. When they tried it in 4 wheel drive, the motor would turn but you need an amount of power on to achieve this. By practising this manoeuvre, they would start to understand how much power was needed to achieve a smooth turn.

It is perfectly OK to use hand brake in 4WD mode to hold the vehicle parked and also as an aid for starting to move easily, for example a severe uphill start.

What is not OK is to break the car (make a moving car slow down or stop) with the hand brake in 4WD mode or to play an action idiot by making a speed U-turn with the hand brake.

If you do not hear or feel any difference after that situation, don't bother yourself with such thoughts.
