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?
Sorry, I was apparently unable to reply to you until several hours later due to restrictions on new forum users…
Dark mode.
As far as I can tell, nothing is missing, it was just that the icons and font were extremely small and had to be adjusted manually in the display settings, to the big difference from the previous “Oreo” version.
I don’t understand where you are going with this?
Still I must add that I have taken another firmware for the ‘vendor.img’ as mentioned above and namely the DTM version (SM-G965F_2_202102065705_y7bp6konpr_fac) because according to IMEI that was probably the previous standard and also the firmware was somewhat newer.
On the one hand, I am of course happy that it has now worked at all to install the Q version of /e/ on it after all. Would I like to have a “clean” installation? Of course that would be the absolute non-plus-ultra.
Addition
I have successfully flashed a new firmware to the “stock” Android 10 using Odin. I found the correct firmware here. https://www.galaxyfirmware.com/model/SM-G965F/DBT/G965FXXUFFUE1
and then I could install newest TWRP and /e/ dev Q version successfully with your HOWTO Guide!
The (7) adb sideload wasn’t working for me, so I did it with, the (8) SDcard method.
@manoj, could w/e/you host an Android 10 vendor image for the s9 /s9+ device in ecloud.global ?
and recommand thoses steps as a workaround for those who have already OTA updated runned the easy installer on s9/s9+ are desapointed with their Oreo, and are afraid about flashing
if
updated to Samsung-Android-10 on the s9 / s9+ → did the easy installer process [ emulate heimdall + unlock the bootloader + flash twrp to /recovery + format /data + reboot to recovery ? + wipe /system + install dm-verity + vendor 2018 + emulate adb + sideload e-0.17-o-stable from the computer (to /boot and to /system) + wipe /cache and /dalvicARTcache ] = /e/Oreo on the device
Then is
→ boot TWRP → format /data + reboot to recovery + wipe /system → install android 10 based vendor.img → install /e/Q.zip from SDcard (to /system and to /boot) = regular /e/Q on the device ?
It would help if the ‘Easy Installer’ would name the version it will install - then if you want a newer version that the installer does not support, you can install it manually. This would have saved me a lot of trial and error, and probably others as well.
