W204 not cranking

Hello everyone My C250 2012 was having a low battery, i was jumping it and everything was fine, i got a vacation for a while and came back to turn it on but it won't even with jumping, so i changed the battery with a new one but still it's not cranking, now those symbols are on the dash and stereo. Anyone faced this issue before or how can i start my car at least to take to a garage?
I uploaded the video for the same on wetransfer also

Good day,

Most probably you have a blown fuse(s). This usually happens during jumpstarting due to the sparks and the accompanying voltage fluctuation.
If all fuses (engine side & inside the car) are good, check for potential rats eaten wires since you have parked the car for some time during your vacation.

For any additional assistance please let me know.

Regards.

You just need to pull this plastic cover and you will see many fuses behind it.....I'm leaning toward a blown fuse because you have many affected systems popping up messages due to the missing power I guess.

Please send me the picture of your car chassis number (VIN) and I'll try to get you more specific information to your car. The number is usually on a black sticker when you open the door or at the bottom of your windshield, it's a 17 digit number.
By the way, are you able to put the gear in neutral and turn the steering in case you need to put the car on a recovery truck? This is important otherwise you can't take the car easily to a repair shop/dealer if needed. Hope it will end up a simple fuse issue.
I'm usually interested in similar concerns and hope to be able to assist.

For reference the issue is the ECU was fried due to multiple tries of jumping (maybe wrong jumping as well), i bought a second hand ECU reprogrammed it and everything went well.
