Bin file 0 bytes issue

[Muk_IT]

I tried to scan the 0411 PCM in my LQ4 swapped blazer and the bin file was 0 bytes. below is what was displayed, I saw someone else post a similar issue and it would up being an OS issue, is that the same issue I am having and if it is the same issue is there a way to get this to download? I am brand new to tuning in general and definitely new to Universal Patcher/PCM Hammer.

This can happen when trying to read an hptuner custom OS. LSdroid will usually read them, but you get an unknown operating system error you have to click past when doing so. Then again, your issue could be something entirely different.

Yep, unknown OSID. The next release of PCMHammer works a bit differently and will still write the file, but this one will not. You can overwrite it with a standard operating system or one that is in its internal database, then it will work properly.
