No there is presently no solution for work around for mobile data but for the phone struck up issue there is solution which allows u to get back to stock 4.3 without any issue.
1. Download the stock modifed (i.e bootloader file removed) MD4 tar file 'http://anything-android.co/getdownload.php?file=D2USC%20Fix/D2USC-No-aboot-md4-fix.tar.zip'
2. Download the OTA MJA file from 'http://anything-android.co/getdownload.php?file=D2USC%20Fix/md4_to_mja_ota_update_2.zip', copy the downloaded file to your SD card
3. Install the first downloaded MD4 file via ODIN PDA section and after completion of the process and cache cleadning after phone booted up when phone is at "SAMSUNG" logo switch off the phone and boot the phone to recovery mode i.e "volume up + home + power buttons" and select install update from SD card option and navigate to the downloaded file in the step 2 and press OK and it will be install the OTA update package it will take some time for completion and after that phone reboots and now u will be on stock 4.3 MJA
