I posted this over in the GetLogs thread but since I know there were unique issues for NAND and not everyone that hangs out over here makes it over there, I'd like for anyone using GetLogs on NAND to try out the new version here:
xda-developers - View Single Post - [APP] GetLogs - Get dmesg, logcat, radio, etc with one click!
You can see some of the changes in that post, mainly it fixes a huge bug with the "just a file" option, it also limits the size of the output to 1000 lines per log, to prevent OutOfMemory Exceptions.
