[AT&T Samsung Galaxy S7 Edge Questions & Answers] xjimmy:
"Downloaded the one said to do 5 DIFFERENT ONES that are essentially the same," what does that mean? You downloaded the firmware zip file that had 5 seperate files in it, and they're all essentially the same? See how you quoted one of the files inside? Notice how it starts with "AP"? In odin, you click the AP button, then add that file in that AP slot. Then the one that starts with "BL" in the BL slot, and so on and so forth, until you have all 5 files in their respective slots. THEN you start the flashing process. Did you do that? If that didn't work, did you make sure the md5 number listed at the download screen match after you downloaded the zip file? Do you have an md5 checksum program on your computer? You can easily find a free one by doing a quick google search. You could also maybe try downloading and flashing a different/newer stock AT&T firmware.

As for xposed, you first need to download and install this version of the xposed apk from the xposed website: XposedInstaller_3.0_alpha4.apk

Then, if/when rooted find and flash this version of xposed framework in flashfire:

xposed-v85.1-sdk23-arm64-custom-build-by-wanam-20160530.zip

If you're not having any luck, and your phone is still stuck in download or recovery mode, you can still power it off for the time being using the following steps:

If it's in recovery mode, you'll have options listed, like "reboot system now," and, "power off device." You can toggle through each choice using the volume up and down buttons, and once you highlight the one you want, hit the power button to select it. You can go to "power off device" in recovery mode and turn your phone off for now if you don't want to have to worry about it. If your phone is in download mode, it'll either be at the warning screen where you can hit volume up to continue, or volume down to cancel and restart the phone. If it is all the way in download mode, it'll say "downloading... do not turn off target !!" If it is on the warning screen, just continue into into download mode. If it is in download mode already, or you just continued into download mode, and you want to turn the phone off, press and hold volume up, volume down, power, and home button and hold them all down at the same time until the phone shuts off. Immediately after, let go of all the buttons, and then press and hold the volume up, home, and power buttons until the phone comes back on, and in the top left corner, in blue, it'll say "Recovery booting." It is then that you let go of all the buttons. You will enter recovery there and be able to power the device off.

Anyway, I hope you already got it fixed, and if not, I hope this information helped. I'm not trying to be mean, but you really need to search through all of the forums, read everything, read people's comments for information on how to do these sort of things properly, and how to fix the problems. Rooting, installing custom roms and xposed is a little different on newer devices now. Mistakes can be much more costly now than they used to be, so unless you've read thoroughly on such processes, and/or have found a youtube video that helps and you're feeling confident about it, you might want to reconsider attempting to apply these kinds of changes to your phone. If you have any friends that are good at this stuff, maybe that would be another way as well. Anyway, best of luck to you.
