Can not install on Galaxy S5 duos

[ant0ine]

Hi

I would like to install /e/ on my smartphone but I have some issues.

My phone is a Galaxy S5 LTE Duos (G900FD) and it is supported by /e/ https://doc.e.foundation/devices/klteduos

I follow this install process
https://doc.e.foundation/devices/klteduos/install

and I am stuck at

adb sideload e-1.21-r-20240323388943-dev-klteduos.zip

with a message similar to “signature verification failed”

I enable USB debugging but was not able to perform an OEM unlock (can not find this option).
I did not install TWRP either.

I am running Debian 12

antoine@talos:~$ adb version
Android Debug Bridge version 1.0.41
Version 29.0.6-debian
Installed as /usr/lib/android-sdk/platform-tools/adb
antoine@talos:~$

hello @ant0ine, welcome to this forum.

@ant0ine

i was not able to perform an OEM unlock, (can not find this option)

there was no need to allow the unlock of the bootloader in develloper-option on this device generation, it was simply did when you install a custom-recovery-manager.

@ant0ine

a message similar to “signature verification failed”

it is common as the build is not Samsung-Official, just don’t ask for a verification

@ant0ine

I am running Debian 12
Android Debug Bridge version 1.0.41
Version 29.0.6-debian

I had issues on upgrade to Debian 12 and there are some other reports of strange behaviour

First I would suggest that you really must be on latest platform-tools (not the older Debian version you are using).

Caution: The default adb installation on OS like Ubuntu can be outdated and can cause errors. We would recommend that linux distribution users ensure they use the installation process given here

• https://doc.e.foundation/pages/install-adb

However I suggest you are sure to retain Debian’s

android-sdk-platform-tools-common

and check that Debian already met this: Each user that wants to use ADB needs to be in the plugdev group. … add yourself to it using the following command:

sudo usermod -aG plugdev $LOGNAME

what should I do to not ask for verification ?

[ant0ine]

I tried once again to install /e/, here is the results

antoine@talos:/document/tel$ adb sideload e-1.21-r-20240323388943-dev-klteduos.zip 
Total xfer: 2.00x                                                  
antoine@talos:/document/tel$

my phone displays this message

E:failed to verify whole-file signature
E:signature verification failed
Installation aborted

[ant0ine]

I tried several times and I finally did it

Here is what I did

1 > install twrp with heimdall (odin not available on Debian)

• boot in download mode ( Volume Down + Home + Power)
• then heimdall flash --RECOVERY twrp-3.7.0_9-0-klteduos.img

2 > install /e/ os

• boot in recovery mode ( Volume Up + Home + Power.)
• wipe data
• select advanced > adb sideload
• then adb sideload e-1.21-r-20240323388943-dev-klteduos.zip

[piero]

so, what was your solution ?

use TWRP instead of recovery-e ?
or
wipe /data that you missed during first attempt ?

[ant0ine]

well I think the solution was to use heimdall with TWRP
