I bought a Samsung Galaxy S9 from the /e/ shop with /e/ preinstalled.
I always kept my smartphone up-to-date, I had the 0.20 version until yesterday and every update worked perfectly until this one.
I saw the notification for an update to version 0.21. Download thru the settings app worked fine. Then, the phone installed the update (via TWRP, without any error message). Then it reboots in a loop.
The problem : I have the “Galaxy S9+, powered by Android” screen (by the way is this normal ? I have a S9, not an S9+). After a few seconds, it switches to the /e/ logo with the jumping dot. The /e/ logo stays here for one minute, then there is a black screen during 1 second and again the “Galaxy S9+, powered by Android” screen. This happen in a loop and it never boots correctly.
What can I do ? As /e/ was preinstalled I hoped not to have any problems with updates… I don’t have a backup phone so it would be really cool if someone could help me.
I received an answer from the helpdesk but it didn’t solve my problem. I’m waiting for their next e-mail but in the meantime I was wondering if someone knows which steps are in the second point of this tutorial (the toturial is not complete) : [HOWTO] The system doesn't boot (bootloop)
Other question before doing anything wrong : could a factory reset from TWRP solve my bootloop problem ?
While the ROM might be corrupted, maybe something prevented the phone from receiving the Upgrade correctly - I do not know the method of Upgrade, so it is unhelpful for me to speculate further on this.
I hope that the /e/ team is trying to figure the most risk free way to get you out of this. Only if you felt you had to continue without that support I would think that you would have to prepare to take this path Revert Samsung Device to stock ROM on Windows PC then a “start from fresh” install of /e/ using a Q dev ROM as above.
Thank you for your precious help ! I’m sorry to answer a bit late but I installed 27_ARI9.zip before reinstalling /e/ 0.20 today and… IT WORKED !!!
My phone is now fully functional, thank you !
After booting the phone, I there was a “system update” notification to upgrade to /e/ 0.21. I tried to upgrade but the same problem happened : bootloop ! So I reinstalled /e/ 0.20.
This is quite annoying… I’m stuck to /e/ 0.20 now… I suppose that I will have the same problem for future versions
I think it’s a bad thing that you have to deal with this kind of problem when you buy a phone with the system pre-installed. Everything should work properly, the software has to be stable and functional. I really like the work that the /e/ developers are doing but it’s this kind of problem that prevents me from recommending /e/ to people around me
Anyway… Do I need to do future updates ? It’s quite risky, isn’t it ?
Other question : if I encrypt my phone, can I still access my date via TWRP ? (can TWRP decrypt the content of the phone ?)
Thanks again for all your help and responsiveness !

In fact, this should have been a “one off” as you could check by following some of the threads sharing this tag #ota-upgrade. Many users had a successful experience, except perhaps a dozen of you covered in the list above. I think you are saying that you took the path of “going back” to Oreo - in which case, it would look as if you tried again (by upgrading to 0.21, Q, Android 10) to do the failing Upgrade.
There is no news that I have seen on the optimum fix.
The way that developers are made aware of these issues is when someone tells them. We do this in this way Report an issue, (new users might possibly face a login issue which is fixed by sending exact details of the failing login to email@example.com)
Following the link I gave you above, takes you to the issue raised there
If you add to that please be careful to show where your situation is the same, but particularly where it is different (in that I think you downgraded to Oreo).
You will know that you can demonstrate whether you have “Oreo | Q” and also “stable | dev” from
Settings > About phone > Android version > /e/ version.
It is reported by others that this does not work on every Samsung, but if you long press on /e/ version you should be able to “Copy to clipboard”
