I solved it by running a windows WM with Odin. Flashed with success
Probably use pico as mentioned above, and don't forget to reboot to fastboot /recovery to install it right after installing latest 17.1 if it doesn't work if you install it directly after. Anyway, don't let it boot system first.I tried to install the latest 17.1 on my T813 and the corresponding open gapps arm64 10.0 but after some time of booting, it always ends up in the recovery again. The same when I force reboot as described in the OP.
Tried the same with 16.0 and open gapps arm64 9.0.
The only way it worked once, was when I didnt install any google package. What can I do? I tried to do everything correct...
I'm in the same boat, also tried 16 and 17 but opted out for going back to stock as I want LTE to work. As far as I know, there is no workaround. It's a shame really as it's still a really good tablet and a fully working ROM could give many devices a second life.I had almost forgot my wife had this tablet (T719 8" LTE), so I was glad when it showed up in a drawer and it actually still booted. Stock ROM is nice but Android 7 is getting too old and where is the fun without a homebrew ROM to try ? I tried both LOS 17.1 and LOS 16 and opted for the latter which feels more polished (SELinux enforced, it passes the safnet test, camera works fine).
Just for confirmation:
both Android 9 and 10 are "abandoned" and will not receive further security fixes; I think also LOS 16 and 17.1 are not actively developed, changelog for both is rather empty for the latest months. So I guess any recent build is fine, I am not expecting any change in recent builds.
In both LOS 16 and 17.1 LTE is not working, the sim card is not seen and it cannot be accessed. Any hope or workaround to have it working ? It's the only missing feature to declare LOS 16.1 almost perfect.
Regarding a), if you don't want to root, you can remove system apps with adb:Keeping the stock ROM is an option, but a) is bloated with goggle and samsung stuff you cannot remove (and some of the samsung stuff no longer works at all) b) android 7 is slowly but inexorably loosing apps support - and one such app is nova launcher (android 8 minimum) which to me is a must.
I like LOS 16, it is lean and clean and I can choose to install only the minimal google apps I use; I will have to live without LTE (99% of time the tablet is used at home). My S2 would also need a new battery, but i'm not sure it is sound to invest money in it. Really glad it still works as a reading/youtube/Netflix tablet albeit with wi-fi only and a limited autonomy.
Yes, mine is doing that too, at 15% of battery it reboots itself; peak current is no longer what it used to be...
