I made an update for this device, enjoy :
Don’t forget to backup and share your experience, thanks
I have tried to install both of these images on my SM-T377P (gtesqltespr) and I get bootloops. All I get is the Samsung Galaxy Tab logo for a few seconds then a second long vibration with a dark screen and repeat.
I connected the USB cable to my computer to attempt to capture a logcat but it doesn’t show that a device has connected.
I tried to use terminal in TWRP to capture the file /sys/fs/pstore/console-ramoops but it doesn’t exist.
I am using TWRP 3.2.3 from www.msm8916.com/?view=downloads&codename=gtesqltespr
Got any suggestions how to troubleshoot this further?
Have you tried :
reboot to recovery,
wipe /cache and /Dalvic cache
reboot to recovery
wipe /cache, /Dalvic cache, /data
Before installing /e/ I used TWRP to wipe cache, Dalvic cache, system and data, then rebooted back into recovery to install /e/ from July 2020 that I had previously downloaded onto microSD card. I encountered a bootloop after /e/ finished installing and I rebooted into system.
So then I downloaded /e/ from October 2019, used TWRP to again delete cache, Dalvic cache, system and data followed by another reboot into recovery then adb sideload of the older image, which also bootlooped.
I have since reinstalled Lineage Oreo from two years ago onto my tablet until I can figure out what else to try.
