[Sprint Samsung Galaxy S6 Edge] peabody42:
Hi folks,

just posting this writeup thinking maybe it might be of help to some people.

Started with a clean S6 Edge straight from Samsung repair for broken screen. Factory wipe, KNOX reset. It had the PD2 update. Tried using Skipsoft's Toolkit and ponied up a donation to get the Pro version with the S6 Edge 6.0.1 update, but it didn't work: it got stuck at the "SEANDROID NOT ENFORCING" screen after flashing TWRP 3.0.2. I know there are issues with 3.0.2, but it's what's optioned in Toolkit now.

Flashing TWRP 2.8.7.0 results in normal boot, but I could not enter recovery mode for some reason. 3.0.0-0 didn't work, either.

What I ended up doing is forcing phone into download mode (Power+Volume Down+Home), ODINing TWRP 3.0.2-1. This resulted in a bootloop (somewhat expected). But I could get into recovery easily. From recovery, I flashed Renegade's PD2-Aroma V3.0 Full ROM via ADB sideload. After a very long first boot, everything works 100%! Root, SuperSU, etc., all taken care of. Hotspot works.

Notes and tips:

- While I didn't use Skipsoft's Toolkit in the end, it's still worth supporting. Might work smoothly using 3.0.2-1 instead of 3.0.2.0, but I'm comfortable with adb/fastboot/etc. so just ended up using that. If you don't already have Android SDK and tools/platform-tools, Skipsoft conveniently includes those commands in its directory under C:\Unified_Android_Toolkit (they're named adb-toolkit and fastboot-toolkit. You can copy and rename them as "adb" and "fastboot" for convenience).

- Make sure you get the right TWRP 3.0.2-1 device version. You want to use twrp-3.0.2-1-zeroltespr.tar.md5 for Sprint S6 Edge. Remove the .md5 part and set it to use the .tar extension (stupid Windows asks you to confirm file extension type change).

- In TWRP you can either push your custom ROM or sideload it. To push a file, move the custom ROM into the same directory you've got adb/fastboot for convenience. Open a terminal window in that directory, and either "adb push customromfilenamehere.zip /sdcard/" or in TWRP, click Advanced/ADB Sideload, and enter "adb sideload customromfilenamehere.zip".

- If you're sideloading it, it's gonna take a while, and will start flashing even while the transfer percentage is creeping up. Example: at around 9%, it started AROMA, around 14%, it went through some of the installation options. It was done flashing everything and ready for reboot even though the terminal window said only 76% was transferred. That's ok. Click "finish" in AROMA on phone, reboot. Unplug phone. Wait a long time for first boot (this took around 20 minutes for me). ENJOY.

Remember: all is not lost as long as you can get into download mode! Power-Volume Down-Home until you get to screen prompting to get to download mode. Volume up to select that mode. You can ODIN from here.

Additionally: if you find yourself for whatever reason stuck at the initial S6 Edge boot screen with "SEANDROID NOT ENFORCING," you might be in some kinda of boot limbo. I was able to issue some adb commands here, even with recovery was borked and the phone didn't boot all the way. Doing an "adb reboot-bootloader" would let me do a complete boot to ROM while I was trying to get the different TWRP versions working (until 3.0.2-1).

Hope this helps someone.

tl;dr: For PD2/6.0.1 Sprint S6 Edge, manual flash TWRP 3.0.2-1. Push custom ROM through Recovery. Reboot, wait a long time. Success!
