S21 Ultra can't wipe cache partition since April patch

[DaveB87]

After finally getting the update through this morning (O2 are just slow!) I thought I'd do a bit of maintenance on the phone. Now I'm unable to access the bootloader menu and can't wipe cache partition anymore. Is anyone else experiencing this?

After reading issues I re-visited & updated this reply from below.

Managed to get into boot loader.

release power & up volume the split second, just "Samsung" comes up, before! the 2nd line. worked plugged into PC & charger indicator was still going round.

Thought I had tried every timing possible,

Solved, for me. so ignore below.

Same here,

tried every combination, plugged into PC, charger or nothing at the other end.

Just reboots as normal.

PS

I have posted elsewhere but mainly was asking as the text seems to have gone from the edge pull out menu, Icons only.
