Hey!
I am getting this tab in 3 weeks, is there any "1 click root" method like vroot? If not can someone help me what to type in CMD? (i've installed cwm recovery on other my devices and custom roms too but they were way easier to root with one click methods)

---

You would need to use v1.0 for now. Safariking is fixing the v1.5 to make it all correct again. Have fun in the meantime folks and a good new year!

Much Easier...
FYI, change step 5 to then reboot system from twrp and choose to root the rom when prompted.
after booting into the OS using TWRP prompts of "play" and "normal" installed binaries and rooted no problems. no sideload or adb necessary.
TWRP handled this all just fine for me.
I also had to use Odin 3.09. 3.07 failed for me 3 times in a row.

I followed the instructions, but after it updated the firmware (first stage), it rebooted and went straight back into the normal OS, no changes.
Now when I try to access the download mode it won't - just keeps rebooting to normal OS.
Anyone any ideas? The Log bit from Odin says the following:

I've attached a screenshot of the ODIN window.

it sounds like your problem lies with step 4 and 5 after the flashing in odin is complete DONT let it reboot to android... when odin finishes and the tablet turns off and back on press and hold press power+vol up+home until it reboots the first samsung logo at which point let go of the power button and continue to vol up+home until you see TWRP logo now when in twrp just select REBOOT and then SYSTEM after android boots proceed to step 6 and 7 and you should now have root..

Awesome thanks for the help!

You should give credit to the original post as it did from ShinySide. This guide has been around for quite sometime now.
http://forum.xda-developers.com/tab-4/general/root-galaxy-tab-4-7-t230-t2835264
Added: it's still working on the latest firmware.
Can't remember too well: I too let it reboot after odin but no problem going into TWRP (note the difference in combo buttons) and select Reboot and it will has a choice to root. No need to odin again.

Got there eventually, just need to find some decent roms for it now!!
