Hi @marcih83, yes, I think it’s a beginner question :))
But those who don’t know should ask so they can move on.
Samsung stock firmware is available on various channels. Two reputable ones are sammobil and samfrew. Samfrew has the slightly faster free download, but it still takes hours to download the zipped 4.65 GB ROM.
I top it with another startes question for the joy of the community.
So it means I need to dumb the full official Samsung os first over my /e/ os (via Odin I guess) and then flash the new /e/ update?!?
So there is no way to use a file like “VENDOR-27_ARI9.zip” ,that was used to get the pie version running?
@marcih83, we were all beginners once. And I’m still learning every day. And this learning is fun …
Well, it makes sense for me to install a stock Android 10, because it updates not only /Vendor, but also the bootloader and the important /EFS (modem and more).
The software jump from Android 8-Oreo or 9-Pie to 10-Q is a big one. For future-proof S9 / S9+, I think it’s worth the work. Tinkering around does not pay off. The S9 / S9+ is still a valuable phone. It deserves the best conditions to remain operational for a long time.
I’ve installed /e/ OS Q on my S9+ this morning, after the long wait! Most apps are running OK so far. Its been a while since I tried /e/ Oreo on the S9+ so looking forward to giving Q a decent run.
Just a quick question @SuzieQ to your knowledge does this Q version have 2-button navigation? I haven’t been able to find anything myself.
Well, for LineageOS there is a ‘Magisk’ 2-Button-Navigation app. I use /e/ OS deliberately without root (Magisk). But I will try this app for you. Not today - but in the next few days. Please remind me if I forget about it.
Hi @Sean, I was able to install the 2-button navigation app successfully and it is also displayed under ‘Modules’ in the Magisk Manager, but there is no option(s) for it in the > System > Gestures section.
At the moment I can’t tell if I made a mistake or if the app doesn’t work with /e/OS ‘Q’.
Fyi, I tried skipping flashing to stock Android 10, and tried to flash to the new Q first (with TWRP 3.5). Got missing vendor errors, so it seems that you really do need to start with flashing a stock ROM.
I am still trying to find a stock ROM zip file that will work for me (getting corrupt file errors), I’ll make a follow up post if I succeed.
If you’ve successfully upgraded to Q can you decribe what you did, where you got stock Android 10 files, etc?
I have tried sideloading a couple of stock Android 10 ROMs from samfrew and get corrupt zip file errors when trying to sideload with TWRP 3.5. Copying the same ROM into the phone directly and installing from within TWRP does not work either. I am trying to see if files from sammobil cause the same errors, just waiting on downloads.
I’m in the USA, but have no idea which stock Android ROM will work, so I’m just guessing - does this mean that I cannot upgrade to Q?
The .ZIP files from samfrew must not be installed via sideload or via TWRP 'Install'.
Samfrew’s G960FXX......-202101.........zipmust first be unzipped. You’ll then receive a maximum of five files (AP, BL; CP, CSC, HOME_CSC) with the file extension .tar.md5.
The four files (AP, BL; CP, CSC) .tar.md5 must then be installed via Odin3 or Heimdall.
Since you are using a European Galaxy S9 ‘starlte’, I recommend using a ROM for the BTU (United Kingdom) or NEE (Nordic Europe) region. This will also work in the USA.
