The guide is also useful to flash back stock firmware ... which is needed to get OTA updates to work again.
Please use the guide thread or the S4's Q&A/troubleshooting forum (which I have also linked in my previous answer) for further questions.
XDA Assist is only for pointing you to the best place to get help.

[Completed] how I flash my Samsung galaxy mega 6.3 att sgh-i527?

The screen was broken and I give it to a friend to change it, but when he fixed the phone lost the configuration. Just start in Samsung logo and restart in a bootloop. Not access to recovery mode, only download mode. Not recognized IMEI or s/n in kies.
I also try kingo and doesn't work, also several room stock for the model and always have two kind of error: secure check boot and secure check pit..
When I tried odin, the phone stopped and the process for flashing not advanced just get stuck. If I used a pit file for the phone have error. So I need help for this.
thanks
Hi
Thanks for writing to us at XDA Assist. Your device forum can be found here:

That way your question will be seen by folks who own your device and therefore are the most qualified to answer your question. In order to post in that section you'll need to create an XDA account, but that only takes a couple of minutes.

The CM12.1 that I'm finding is probably the one you already have, it's the only one here for your device so it won't do you any good for me to link you there.
