5 years ago HI Guys apologies It would seem that my issue isn't due to TWRP, Magisc or any other app i have running. The issue lies with either the hardware or the stock image i got from Sammobile.com. Being a noob, during my experimentation i have had to flashback to the stock image on several occasions. Only discovering the Bluetooth issue when putting my work to good use and using the device.
Yesterday i tested the theory. Flashed it to stock, booted to OS and skipped all the config disabled WI-FI and DATA so it couldn't pull updates. Tested Bluetooth and the issue is present. The Bluetooth did work correctly before i started rooting it. This is unlikely a hardware issue so can only assume its an issue in the build i have from Sammobile. If any of you have access to a stock pre-installed rom that works that hey could give me access to do some testing or indeed any advice it would be very much appreciated.
Device = Samsung Galaxy Tab S4 (SM-T835) PDA = T835XXU2ARJ3 CSC = T835OXM2ARJ3
Many thanks
hi Everyone,
new to the android rooting, However i recently got a new Samsung Galaxy Tab S4 sm-t835 and for various reason wanted to root it.
Device Galaxy Tab S4 SM-T835 *twrp_3.2.3-2_sm-t830_26918""
WHAT STEPS WILL REPRODUCE THE PROBLEM?
Put your device in DOWNLOAD mode. (Hold POWER + VOL UP for stock recovery use UP button to highlight Bootloader then Power button to select it and enter Download Mode )
Run ODIN and first flash the custom patched kernel below using the AP slot. This is necessary to disable dm-verity otherwise your device will not boot. This kernel is also switchable to permissive mode. T830XXU1ARH8_dmverity_patched_boot_permissive
Once your device reboots put the device in download mode again.
Restart ODIN and uncheck Auto reboot.
Load the file below into the AP slot and hit start. twrp_3.2.3-1_t830_26918
After flashing and ODIN reports PASS immediately force reboot to recovery. Do NOT let the device boot to the OS. You should now see TWRP recovery. It is now safe to boot to the OS
WHAT IS THE EXPECTED RESULT?
Once in the OS any paired Bluetooth device should be retained after a reboot or from exiting airplane mode
WHAT HAPPENS INSTEAD?
All Paired devices are lost and need repairing
ADDITIONAL INFORMATION
Flashed back to factory and everything works as it should, Repeated flashing the recovery partition and agin BT Devices are no longer retained across reboots
