Cannot flash iode 5 on Galaxy s10e

first i tried flashing iode 5.4 via twrp (after factory reset),
it says “updater process ended with ERROR: 1”.

then, i tried using odin to flash iode-5.4-recovery.img,
odin shut itself everytime i pressed start.

tried iode 5.3 as well, same result.

anyone has similar issue? or is the problem on my end?

i have got into iode recovery via heimdall,
however when i flash iode 5.4, it again says "ERROR: recover: Error in /sideload/package/zip (status 1)

Hi,
what processor does your S10e have? Snapdragon or Exynos?

Have you tried flashing the latest non-beta (4.xx)?
