Upgrade 311X MobileOdin My Experience
I tried to upgrade using MobileOdin with P3113UECMH2_P3113XARCMH2_XAR. I chose to not flash recover so that my CWM would remain in tact. I choose to Enable EverRoot. I did not: inject Superuser, Mobile Odin. I tried both with wipe Data and not Wipe data. I tried different Superuser apps via flashing with CWM and Playstore, being careful to have only one app active. I'm sure it might be made to work but I couldn't do it.
The system would come up and after a few choices, the touch response was poor and than a reboot was necessary. It was difficult to get superuser to grant permissions.
I've gotten MobileOdin to work in prior upgrade but failed this time. After multiple atttempts, I flashed with Odin and P3113A_CWM_RECOVERY-126.96.36.199_SUPERSU-0.96_BUSYBOX-1.20.2.tar.md5. That worked as expected.
Should someone else try Mobile Odin, It would be helpful if they reported their experience. I did try an early release last week of 3110 using same procedure with similar results.
