my phone is fully stock currently. Im trying to install TWRP Recorvery into my phone, but there is some problem. i enter download mode, then open up odin and install the recorvery into my phone, odin says pass but still my phone has stock recorvery. ive tried factory reset, cache reset. etc. the TWRP version for my phone is CORRECT. im sure about it.
Phone model is Samsung Galaxy Tab S 10.5
What is causing this problem?
