Help me!

I have a problem with my ROM! Please tell me how can I do? Yesterday, I was ran back up file. Now, my mobile not reponding!
is it stuck in bootloader mode? that's where there's something on your screen like "serial v...something". if yes then you're still okay; just do a couple of hard resets and it should bring it back.
you have to explain a little more though; did you flash / upgrade your rom and then it froze up? or did you back up the system and then it stopped working?
cheers

Please help me, I have YT9216B, bricked .... ATC_Flash_Tool ends the flash, but.....

Let me explain in vreve .... I installed this rom
https://forum.xda-developers.com/android-auto/android-head-units/everything-yt9216b-t4007063
but I had a problem with the reversing camera, black screen, then I tried to install a different rom, but the same as mine and stock, when I gave the command to sp flash tool, Firmware Upgrade was selected, so it made me the format of the head unit, obviously the rom did not finish the flash, and I had to open the unit to make the test point, in the firmware upgrade the preloader was also selected (other bull**** made), in the end on 4pda I read cge maybe it could have been EMMC_PART_BOOT1 corrupted due to the format, so following the instructions I wrote one equal to mine in the head unit, now after several attempts I managed to install its firmware, only that it turns on, shows the androi logo, then reboots and goes into recovery .....
Please help me, I'm getting mad since this morning, how can I solve ...
A heartfelt thanks to all !!
A step forward....

Good morning forum, I update you, I managed to sew boot 1 to the preloader, I tried to flash the same rom that gave me problems with the reversing camera, and now the head unit turns on and goes into boot without then going into recovery, but it remains with the fixed logo and does not go on .... Do you have any suggestions? What can I try to do to solve this problem ?? Thanks in advance, to anyone who will have a good heart to help me ..
Solved great....
I just solved everything ...... I also made a little culture about these units....
