[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Joeyyjay:
Hey Everyone,

I have a huge problem. I have been searching the Web and even this forum for answers. Tried multiple things but I am still having trouble. I heard this was the place to go.

So I attempted to CF-Root my galaxy note 4 from sprint (Model # SM-N910P). I've rooted many of my andriod devices in the past (including samsung products) and have never experienced what I'm about to tell you.

Using Odin I attempted to root this device. It says it was successful then it rebooted. However, it hasn't stopped rebooting since. It's stuck in a boot loop. It loads past the "Galaxy Note 4" logo screen , then past the "Samsung" screen. But once it reaches the "Sprint" screen it stops there for a few seconds then reboots all over again starting with the "Galaxy Note 4" screen.

Here is everything I have tried so far:

- I took out the battery, waited a few mins. Put it back in turned it on. Same thing occurs

-I attempted to re-root. Still says successful. But still boot looping occurs.

-I then did a factory reset. Still occurs

-I then in the recovery menu wiped the data AND the cache partition. Still boot looping.

-Now I have read a fix of having to flash the stock firmware. Basically starting from scratch. I did this through 2 methods. First I found the stock rom file for the variant and specific model. Using Odin attempted to install it (via pda) It failed. (Don't recall what it said)

-Now I found a thread in this forum using its own stock tar file. Attempted to install that. It still failed. I will list the results from that below. I also wanna say I did make sure I had the right updated samsung USB drivers installed before I attempted to install these files. Plus Odin recognized the device no problem anyway.

Here are the results:

AND here is what the results are on the Note 4 itself:

SW REV CHECK FAIL : [aboot]Fused 4 > Binary 1

Not sure if this matters but before the root and this boot loop I enabled developer mode and enabled usb debugging.

So this is everything I've tried so far and the results. I've also re downloaded the file and have attempted this about 4 times already with no luck. Still getting the same fail with the same results and same boot loop. Can anyone give me any more tips here? Or is my phone a goner? I've already wiped this thing. So losing data is no longer a concern for me. I just really need some help. I've tried to be as descriptive as I could cause I know even the smaller details can matter here. If I missed anything feel free to ask me. This is my last resort. Thank you so much in advamce!

I appreciate all and any help on this! :)
