I am trying to install /e/os on a Samsung Tab A7 (since weeks). I worked me through the tutorial of the /e/os documentation. (As a new user I can only put two links in a post and prefered others)
With all recoveries I’m running into trouble while trying to flash /e/os. When doing the adb sideload it says
“Comparing TZ version XF.5.1-01015-1 to XF.5.1-654142-4
ERROR: This package requires firmware from an Android 12 based stock ROM build. Please upgrade firmware and retry!
Updater process ended with ERROR: 1”
I upgraded and retried a lot. I’m stuck since weeks. Firmware is the latest version (July 15th 2024), and yes, it’s for Android 12.
I also tried older unofficial TWRP builds (3.6.0 and 3.6.2), and at least with the 3.6.0 build I run into the same error. (I have other issues with 3.6.2 so I can’t tell.) And of course I also tried the e-recovery (which I don’t prefer since I plan to root with magisk and am not sure if that’s possible with e-recovery)
Have you installed stock, connected to the internet and installed all OTA updates from Samsung before you started? Maybe more than one reboot & update required.
I am running twrp 3.6.0, Vendor Security Update from Samsung 1. January 2024 with Info about gta4lwifi | LineageOS Wiki Perhaps give it a try if eOS version still fails. I was running eOS but the Bliss launcher landscape screen bug was a bit too annoying.
Yes, I installed stock, connected to the internet and installed updates when I did this the first time. Since then I can’t update anything else than things like the calculator. Security update is already up to date. Or do you mean something else with OTA updates (and if so, how can I find them)?
I used the download link you linked to.
We have /e/os running on all devices in our family and now one of the kids needs a new tablet. I chose this tab because you can install /e/os on it. For having the same OS on all devices I really would prefer eos to lineage. (I use lawnchair as launcher on my phone since I don’t really like the bliss launcher).
If I really can’t find out how to get /e/os running I probably will finally switch to lineage with microg, but for now I want to try to find out what I am doing wrong. Or at least I want to understand why it’s not working.
d/e/v only needs to integrate the current identifier of version T500XXS7CXB1 Stock Android 12 Release Date February 2024 in its builds, and d/e/OS-T will no longer block the installation."
That really sounds like the firmware updates are not integrated in the eOS build. Can I do something about it? Who needs to know?
The cause of the error has been known for months, but D/e/v is unwilling to make a small change.
/e/OS-T can only be fresh installed with Samsung firmwareT500XXS6CWI2 Binary BIT-6 (six) or lower.
Without adapting the /e/OS-T to the Samsung firmware, no new installations with Samsung firmware T500XXS7CXB1 or T500XXS8CXG1 are possible. Luckily, there are good alternativ/e/s.
Okay, reporting an issue is actually what I wanted to do initially. Since I was unable to register at https://gitlab.e.foundation I searched for other options to get help and found this community forum.
When trying to register I get an error message regarding my email address. It says something like “E-mail is not allowed for registration. Please use your regular email address. Contact your administrator.” I tried with two different email addresses from different providers and finally gave up on it.
I really would like to add a comment to the reported issue by @piero but I’m running into obstacles all the time. Am I stupid? How can I register?
