Bootloop every 3 minutes after hard shut off (10sec. off button pressed because Samsung S10 plus did not respond anymore).
After startup repetitive boot. Recovery Mode not possible to enter; standard method and also with USB C Data cable attached according to new Android Update.
No information found online about red message on top of startup screen "Erase Fail: Read Only "
Exynos Processor, International Verson, No microSD card used,
unhooked battery (removed back panel etc) which did not clear the issue
Go to nearest service centre. Or download Odin and flash firmware S10+ and don't forget: reset phone. "Flash S10+ firmware" Google it.
Hope your phone will be fixed!
