I was trying to flash twrp for my Samsung galaxy tab 3 using TWRP manager app downloaded from play store.I got some error in between,and it asked me to reboot, Since then it has been contionously looping.
I am not not able to enter download mode or recovery mode using volume up + power + home buttton,tried all the combinations, nothing seems to work.
And also when my phone boots up,i see a red excalamation mark at top left,can someone tell me what does that mean and how to fix my phone.
Even tried connecting to power chord and pressing power +volume buttons.
Please help am a nubie.
