FINALLY made it!

And the problem it self:
I use Ubuntu ot VM and so the option by default of USB was : USB 2.0 ( OHCI+EHCI) Controler.
but my hub is connected to USB 3.0. So I have changed it to USB 3.0 (xHCI) Controler, and the mirracle happend
The instalation procesed fluently.

Probably this should be mention into the manual or some kind of troubleshooting.

Thnaks MrT1001 for you support, and to UBports of course!

Can I use something like this:

heimdall flash boot-reboot-recovery-herolte.img
heimdall flash recovery_herolte.img

but I don't know the right syntax's ....

@MrT10001 - The same. I cant understand whats wrong. Should be easy procedure.
Can I flash UBtouch via TWRP or ADB ?

Hello All,

I'm looking for some help. I'm trying to install UBTouch to my Samsung S7.
Now I'm running Lineage OS 20 with unlocked bootloader, magisk root and TWRP as well.
UBinstaller just do nothing when the phone is in download mode. I tested on windows 10 machine and on linux ubuntu machine with hamidal installed as guides say.
So far I've tried following starting point for the UBInstaller:

1. LineageOS 20, TWRP with root - when the phone is in download mode - do nothing and receives a error.
   2.LineaageOS 18.1, TWRP with root - when the phone is in download mode - do nothing and receives a error.
   3.Flash stock Oreo 8.0 with ODIN > developers option > OEM Unlocked - ON (it was in that state after first boot) > USB debbuging - ON, > Flash TWRP with ODIN > UBinstaller - do nothing and receives a error.

I've tested multiple combination to start UBinstaller - and there is no difference. ADB working fine, but fastboot with hamidal seems - not.

Please give me some advice!
Thank you i advance!
