Thanks a lot RIL works with that patch!this is the fix for ril. flash in twrp
Can't prove it as I haven't got a wakelock detector app installed and just upgraded from ripee's variant (where it didn't work), but so far battery drain is 5% the last hour while the tab was not in use with WiFi and mobile active, so I assume it is _not_ working. It helped before to use Airplane mode (with WiFi on) to achieve 1day lifetime, I'll continue with that if the drain stays as is.
Versions newer than than twrp_188.8.131.52_LL_5.1.1_t710 gets me stuck in a logo boot loop following flash. When I flash that version back, I can again get to recovery. Any suggestions on what I am doing wrong? The goal is to install LOS 15.1/16.0 on my SM-T710 (wifi only).
I've tried the 'treble' enabled image from this thread as well as the gts28wifi/gts28vewifi from twrp.me.
Background: tablet was rooted some time ago with kingo but the ROM was not changed from stock (5.1.1).
Second (maybe related) question: how to determine if my model is SM-T710 2015 (gts28wifi) or 2016 (gts28vewifi)?
Thanks to developers here and other success stories, I'll keep banging my head until I too succeed : )
Indeed deep sleep works, however there is a huge variance in battery consumption. After the last boot I've got optimal battery lifetime as well (see attached graph). The difference to the previous boot is that fingerprint is not working at all now while it nearly worked 100% before the boot.
