I was using CWM recovery 22.214.171.124. I installed the first file, listed at the bottom of the page, the "Kernel.zip file". It installed using CWM just fine, it's a small file only about 6MB. The second file I tried to install, the "T110 on T210/210R.zip" file failed. It gave me something about 5 out 4 expected args and didn't work.
After this my tablet would not boot, it would show the Samsung Galaxy Tab 3 (not the animation) and then go black.
Next I tried to reflash using the 4.1.2 firmware from SamMobile using ODIN. This failed on the modem.bin. After this I couldn't boot in in recovery mode or ODIN mode. All I get is the, "Firmware upgrade encountered an issue...". ODIN still recognizes my tablet.
So I'm stuck. I've spent all night googling to no avail. Any help would be appreciated.
