Got several of SM-J200Y as 2nd hand for a project.
Looks like there’s a bug in this image build – proving impossible to find any other (earlier) ROMs from legit sources.
(Finally!) got TWRP (twrp-3.1.0-0-j2lte.img the only one that works) loaded via Heimdall (had to resort to CLI; frontend gave poor results).
When booting, lock @ logo @ boot with error: “KERNEL IS NOT SEANDROID ENFORCED” in led letting @ top.
(soft-bricked? &) Unable to get beyond this point.
From what I’ve LMGTFY’d, may be some partitioning issue?
Unsure if applying Magisk may have any benefit – too late in morning to grok.
