How to enter Recovery Mode

All stock how do you access recovery mode?
Not, Sony stock doesn't include a recovery mode.

S3 reboot from download mode to recovery using software

Hello together,
I currently want to install a custom recovery twrp for lineage os.
I come to Download mode. But I can't reboot to recovery because the volume up button is not Working any more.
When I reboot in normak mode and from there to recovery mode using adb reboot recovery then the custom recovery is overwritten.
As I read this is a "feature" in the Samsung Software that recovery id overwritten with stock recovery during normal boot.
So the question is: can i boot from download mode to recovery with software. In odin mode i can't connect using adb. As there is no fastboot for Samsung devices I can't connect using a command line adb. So any chance to do it with defect volume up button?
Thanks for any ideas in advance.
Have you root access? I don't think, but if you have you can use "flashify" to flash twrp.img in recovery partition and then use "Reboot to recovery" to boot twrp. You find both in play store.
Edit: you can flash a old 4.1 firmware and use this https://forum.xda-developers.com/showthread.php?t=1695238 to have SuperSU and cwm, then in cwm you can flash twrp in zip file
Tapastalking
Thanks
Hi thanks for the idea. This was the other option but needs root. I thought there is an easy solution with something like adb in odin mode. In fastboot I could do that.... so I thoguht there might be a pendant with Samsung smartphones.
You need root to change the recovery.
Beamed in by telepathy.
It worked but Encryption failed and after the password lineageos hangs.
Is there any possibility to boot into Recovery from odin / download mode using adb or anything other.
With a jig i will come to download mode.
