Was trying to get this phone rooted and backdate the OS to 7.0 and wiped the NAND in hopes that it would clear the 8.0 ver 5 boot loader. Now what, is it completely soft bricked? I can load the firmware but it sticks in a boot loop on the recovery update!:eek:

You can't... You can't downgrade bootloader on this phone

More details may help...

The phone starts to boot into recovery, then says "installing sys update" then splashes...
"#fail to open recovery_cause(no such file or file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
dm-verity verification failed...
E:failed to mount /cache (invalid argument)"
then it loops back into recovery.

Do you have the right firmware? What is your device...G 930p? The modded Odin? Also, maybe redownload the firmware file again.

Yes it's the right firmware, correct it's a SM-G930P. Didn't know the modded Odin made a difference, I've tried both versions of Odin...
When I flash the firmware now it fails during the "boot" part of the firmware upload.

Well, turns out it might have just been a garbage USB cable! :confused: Got the phone reflashed, but now there's a NEW PROBLEM! Phone boots now but I go through the WiFi and agreement boxes... But as soon as it does that and chews on the next "welcome! preparing your device for first time use... This may take 3-4 minutes" it then just reboots continuously back to that screen! :eek:
