Stuck on installing e/os on Galaxy S9

[frisober]

I am trying to install e/os on a Galaxy S9, but I am stuck.

When I do what I think is required in the terminal, I get a message that does not help me, and the blue download bar does not appear either.

Description: Flashes one or more firmware files to your phone. Partition names
(or identifiers) can be obtained by executing the print-pit action.
T-Flash mode allows to flash the inserted SD-card instead of the internal MMC.
Use --skip-size-check to not verify that files fit in the specified partition.
Note: --no-reboot causes the device to remain in download mode after the action
is completed. If you wish to perform another action whilst remaining in
download mode, then the following action must specify the --resume flag.
WARNING: If you’re repartitioning it’s strongly recommended you specify
all files at your disposal.

I have repeated the steps several times, but I am not getting anywhere.

What am I doing wrong?

Who can help me? Thanks in advance.

• From terminal application on PC, navigate to file path where you have downloaded the recovery-e-for-your-device.img or the TWRP-for-your-device.img, (could be in the “/platform-tools” folder
• execute the following command to install it .

using Heimdall

$ heimdall flash --RECOVERY recovery.img --no-reboot

So you command should be :

heimdall flash --RECOVERY recovery-e-3.0.4-t-20250711507810-community-starlte.img --no-reboot

• From the folder where the files are
• Without / before the file name
• With correct file name, without space between file name and file extention

@piero

heimdall flash --RECOVERY recovery-e-3.0.4-t-20250711507810-community-starlte.img --no-reboot

Thanks for your quick answer but… I did paste the line you gave and the phone says "Downloading’ but nothing happens for hours already.
In the terminal I find:
riso@friso-HP-ProBook-650-G1:~/Downloads$ heimdall flash --RECOVERY recovery-e-3.0.4-t-20250711507810-community-starlte.img --no-reboot
Heimdall v2.0.2

Flashing the custom recovery take less than 2 minutes

Then :

@piero

…NOW COMES THE CRUTIAL STEP !..

• To get out of the Download mode you must Force Power Off your Samsung device,
  (on some old devices, unplug the device,)
  hold Volume Down + Power.
  release when you see the screen turn off…

• immediately Boot to Recovery before any other boot mode attempt,
  hold Volume up + Home + Power
  release Power when you see the very little blue line in the top of the screen…

…IT WAS THE CRUTIAL STEP !..

.

you can read this custom recovery first boot explanation by @aibd

.

You must successfully end with the “recovery-e” main screen :

.

.

if you see something like that :

.
It FAILED ! that is the Official Samsung Recovery screen !
Please re-read and retry the flashing process

I fiddled around with it for a while and finally got it working.

Thanks for all the help you offered.
