Interesting!My PW3 has updated via OTA to 5.12.2 and lost jailbreak(installed old hotfix). The emengercy.sh didn't work at that verison.However, seeing this post, I went to check my device and found it updated to 5.12.3 via OTA and the emengercy.sh was successfully executed and my ;log is back.In my case, I didn't update it manually but my JB is back.What a surprise!
