[Galaxy Note 4 Q&A, Help & Troubleshooting] XproZayd:
This is what happened....

I was on stock Rom and as time went by it started slowing down on me. Ive never rooted this phone and decided to factory reset the phone. So when i did, the hard reset..... as it went to the Samsung logo the phone shutoff, after right away went directly into download mode. i freaked out and pulled the battery. Then i put the battery back in and it wouldn't boot. So I'm guessing its bricked cause it shows no sign of life at all :( .

I was looking up "how to unbrick a Galaxy note 4" and unfortunately unbrick methods dont exists. I even called up my local Jtag service and He said nothing can be done except sell him the phone for 100 bucks for parts (Which i refuse to believe) .

After reading around for an entire day i came across

Part 1 : http://www.androidbrick.com/ultimate-qualcomm-snapdragon-unbrick-guide-snapdragons-are-unbrickable/

Part 2: http://www.androidbrick.com/unbrick...-you-have-the-right-kind-of-rom-qhsusb_dload/

Ok, so i figured some things out thanks to Android brick ! .

In-order to unbrick all Galaxy Note 4's which run on Snapdragons 805 is to access Qualcomm's Service Port Via [QHSUSB_BULK] ---> [qualcomm hs-usb qdloader 9008]

Now we can use MiFlash 2012 To Unbrick our Snapdragon 805s from a "Hard Brick".

So their are 5 things we need to unbrick all galaxy note 4's:

-MPRG8084.hex <-------------- Main

-8084_msimage.mbn <-------------- Main

-rawprogram_32GB.xml

-patch0.xml

-Settings.xml

If we can find these, we just found the ultimate unbrick solution for all Snapdragons 805 phones.

And after i found all that stuff so complicated, i would like to try this except the note 4 version:

What is Hard Brick?

Hard brick is the state of android device that occurs when your device won’t boot/respond/charge at all. This is mainly caused by flashing corrupted firmware, damaged bootloader, incomplete flashing in Odin/Download mode, or interrupted OTA upgrade. You can't recover from hard brick by traditional methods since your phone is ~dead & you can't enter any Recovery or Download Modes; You'll need to use JTAG (expensive service), USB JIG (cheap, but no gurantee), or this free guide/files to get it repaired.

What do you need?

- Hard Bricked Device: Samsung Galaxy Note 4 (N910W8)

- Micro SD Card: 4/8/16/32 GB micro SD card

- Unbrick Image: working dump with the same bootloader/version

- Image Writer: native commands on Linux/MacOSx or Win32 Disk Imager on Windows

How to recover?

1- Download Unbrick Image for your bootloader from here

2- If you're using Windows, download Win32 Disk Imager

3- Backup all files in the micro SD card you 'll use

4- Write the Unbrick Image to your micro SD card using Win32 Disk Imager or Linux/MacOSX commands

5- Remove battery, Insert micro SD card & then the battery

6- Hold Power + Home + Volume Down to enter Download Mode by bootloader on SD card

7- Flash Stock firmware via Odin & Enjoy

Downloads:

All files you may need are available in this folder

-So if some one can create a "you need to create your own Unbrick Image since I can't share it for the device-specific bootloader. Just run this Unbrick Image Creator in recovery & it'll create "/sdcard/Unbrick_Files" in your internal SD card." for me, id love to try it and see if it works.

I was running Android 5.1.1 With Rogers before it went down and wonder if someone can run the unbrick image creator and create an unbrick file for the rest of the Canadian Galaxy Note 4s.:good:::):)[/QUOTE]
