I am trying to root a Samsung Galaxy 4 tab 7". The box says SM-T230NU with the label "Model: SM-T230NYKMXAR".
I got drivers from here:
which is a slightly different number (has a U instead of M) but matches (ie. Samsung Galaxy Tab® 4 7.0 8GB, Black). I installed these and the device connected to the PC with no problems.
Using Odin 3.07, it detects the device. I click the PDA button and select
CF-Auto_Root.tar, then Start and I get this error:
<ID:0/005> Firmware update start.. <ID:0/005> recovery.img <ID:0/005> NAND Write Start!! <ID:0/005> cache.img.ext4 <ID:0/005> FAIL! <OSM> All now when I restart I get this message:
Now when I restart I get this message:
Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.threads completed. (succeed 0 / failed 1)
I downloaded and installed Kies 3. When I run it, it says "The connected device is not supported by Kies 3". It should be, this is 4.4 KitKat.
So I tried Kies 2.6, and it doesn't connect either. It doesn't give this error message, just keeps trying to connect but doesn't.
What can I do now?
