Can't flash TWRP with ODIN on SM-T835

Search This thread


Jan 17, 2010
I am trying to root my tablet. OEM Unlocking is on, USB Debugging is on, latest USB drivers.
I enter in Download mode, Odin connects, I select in AP twrp-3.5.2_9-0-gts4lwifi.img.tar, click Start. I get <OSM> All threads completed. (succeed 0 / failed 1). Yeah, very useful log...
Here are some screenshots that might help.

I don't have this device so maybe not much help
from your screen shots i see 2 things that will cause your issues
Odin failing at setup connection - While this is a common issue with some PC's you can try the above post or try a different PC.
In download mode: KG status shows Prenormal - so if odin does work twrp will fail anyway. KG state should be in Checking mode. To change this state requires a connection to the internet. As with the RMM state ( now KG state ) it was usually after 168hrs ( 7 days ) but this may vary for devices. Your can try the date method but i don't know if it works on the KG state as it did on RMM state.

    Is a more detailed log for Odin somewhere?
    is a matter of connection ,try with USB 2.0 & not USB 3 or 3.1 - turn off any antivirus - added odin to permissible "firewall applications" ..
    _ before flashing in odin, selected "reset" ..
    try - tablet : 1) load into download mode 2) click cancel 3) load into download mode again 4) click continue 5) flash again .. & GL
    Yes, I had a similar issue a while back, USB 2.0 is needed, anything above that and it fails to write.
