Interesting by ungoogling my digital life, i recently bought a device to test /e/.
As I don’t have a tablet at home, I bought a Samsung Galaxy Tab S2, also based on the reading of this install page.
As I do not succeed to sideload the zip file (failed signature), I discover that it was the TRWP that was not the good one (i was always in official one using ‘update with adb’ menu) … so i search more and thanks to xda forum, I download a good one : it seems that my tablet is the 2015 model (gts210wifi) and not the 2016 (gts210vewifi) (sic).
So, I’m actually inside Trwp for first time but here is now my questions : is it risky to try to upload the gts210vewifi image on my gts210wifi device ? what are the technical specifications differences ? if so, is these differences could affect my installation and definitively put my device out of order ?
First, I tried to install unofficial /e/ build found in this post, but it has failed (error 7).
So, I decide to give a try with lineageOS 18.1 and Yes it succeed to install even if adb sideload show an error at 47%. lineageos worked well.
Then I decide to retry with /e/ and the sideload then began, and this time without error but counter to lineageos, /e/ unofficial is looping on “logo + my data is MY data”.
is this because of the ARB thing that the unofficial /e/os was looping ?
Seems the most likely explanation.
But, @twiny, an edit; did you wipe Data (that is wipe system,data,cache,dalvik) as you attempted to move from Lineage 18 to 7 Nougat. If not that would be good to try. With a “built for Nougat” device you may be less impacted by anti rollback protection. With my older Samsung I have bumped Android versions, various things went wrong but I previously dug myself out!
The important thing is to read before you jump too much. And it can be significant if you installed Gapps in Lineage, that should be avoided when you attempt to downgrade.
You were right, I didn’t think to wipe before trying to downgrade from lineage v11 to nougat v7 …
I just did it, and it has worked instantly like a charm. (despite the red message at boot: kernel is not seandroid enforcing)
I can now go discovering the benefits of this beautiful ungoogled os
PS: However, I had read everything 3 times before starting .
