Samsung j400f dead boot repair help

[Bhagat20]

I have Samsung J400f dead boot, I want to ask what is the procedure to repair dead boot, do I need to write dump provided in shell support or directly I can write latest firmware? Because I don't know the history of the phone, was it MDM lock or not, suggest?

All procedure with eMMC or UFS is same - read-write-erase data

if you think what boot-loaders partititon is corrupted - you need simple write it from dump of by vendor

I sincerely do not understand why people who successfully write partitions to one emmc cannot write them to another ...

all actions for all devices are almost the same

Samsung phones are a little tough to repair dead boot, for other brands not that much of a problem

if difficulties arise, then first you need to write what you have already done and did not work

if you haven't tried anything, what's the point of discussing anything?
