First of all, I’m a novice when it comes to flashing devices. I wanted to free myself from Google and therefore decided to use /e/.
I installed the /e/ OS on my Samsung Galaxy S9+ today, which was running on Android 10, using the Easy installer (snap version) on opensuse Linux.
After the seemingly successful installation, I now have /e/ OS running but this appears to be a “downgrade” to Android 8.1 as a base - this wasn’t clear during the installation at all. There was no information about which version was installed. If I look into the Snap folder and then ‘Sources’ it also only mentions “e-latest-star2lte”.
How do I now get the latest version?
Can I use this Guide to upgrade from 8.1 to 10 (Q) without being on (stock?) Android 10 first? https://doc.e.foundation/devices/star2lte/upgrade
No !
as this page is written for orthers devices that use fastboot commands.
I am not sure you have to reinstall stock-samsung-android-10 as you already were on this version previously. (easier using windows Odin than Linux Heimdall)
I am not sure that I understand you correctly.
The Easy Installer has TWRP installed, so you could possibly do something with it?
These fastboot commands, aren’t they part of “android-tools”? They are available for opensuse in the OBS repos (see https://software.opensuse.org/package/android-tools).
Qu’affichent les infos sur la version de bande de base (modem) dans les paramètres a propos de l’appareil ?
Translation: What does the baseband (modem) version info show in the About Settings?
Le easy-installer a probablement flashé le fichier modifié "vendor.img” évoqué dans la documentation (permettait d’installer /e/oreo par dessus un Android 8, 9, 10)
Il posera problème pour un fonctionnement avec /e/Q
Peut-être peux-tu extraire du firmware Samsung Android 10, le nouveau vendor.img et le flasher avec TWRP ( ou Heimdall ) vers la partition prévue (VENDOR), avant d’installer /e/.
Sinon tu devra réinstaller le firmware Samsung complet, ce qui paraît plus sûr ( plus clair en tout cas, mais fastidieux si tu n’as pas accès a windows )
Avant d’installer TWRP, le patch de decryption et /e/ pour finir
Translation: Maybe you can extract from the Samsung Android 10 firmware, the new vendor.img and flash it with TWRP ( or Heimdall ) to the intended partition (VENDOR), Otherwise you’ll have to reinstall the complete Samsung firmware, which seems safer ( clearer anyway )
OK then I would rather choose the safe variant and reinstall the entire Samsung firmware…
Then once I’m on (stock) Android 10, I can try the detailed guide you posted instead of using the Easy Installer.
How do I get the Samsung firmware back on the phone?
ok I tried odin but in download mode I get a red error message and it doesn’t seem to do anything after that. SW REV. CHECK FAIL (BOOTLOADER) DEVICE : 15, BINARY : 12
I don’t know what I’m doing wrong …
I’m using Odin3_v3.14.4; Samsung-USB-Driver-v1_7_23_0 && this firmware (DBT) SM-G965F_2_20201012211233_hme8eekytx_fac
open the AP_folder.tar.md5
extract the vendor.img,
Boot the device in TWRP mode and plug it to the PC.
copy/paste the vendor.img into your device storage
using TWRP, install the right vendor.img
then using TWRP install /e/.zip
if that don’t work, i am thinking about reinitialising your Bootloader level with a “combination”
I chose vendor image for the first flash, then moved the .zip file of the Q version (dev branch https://images.ecloud.global/dev/star2lte/ ) on the internal storage of the phone and installed that.
Reboot. Now it’s on Android 10
However, everything is sooooo smaaaaaaalll
BUT ok, that will have to wait for a fix later…
BTW will I need to update TWRP in the future? Will that work with future updates?
