i trade the dump giiven , it gives me secure boot error but it does proove that this methode is the right one, you just need to extract dump from working phone , find a 32 GB SD card, flash the dump to the SD card ( in windows with win32Disk imager or dd command in linux) put the sd card in the phone, and bam it vibrates

@leptdre, you don't even need dump. It can be done with unpacked .kdz file. First, write PrimaryGPT at the very beggining of sd card with winhex or hxd for example. Then, when you plug the card again to PC you'll see same partition table as in phone and just write bootloaders (aboot, boot, sbl1, tz, rpm, laf, recovery should be fine) to the apropriate partitions from extracted .kdz on SD card (emmcraw tool is usefull here), then use it in phone.

It might take a bit more time to prepare such card, but will work the same. microSD card method is on the other hand useless for phones that died (or started to show secure boot error) on it's own. You may revive such device once or twice but it's often issue with dying eMMC chip anyway.
