As some of you already know, I made my way on the S5 forum. I sold my N3 a few months ago. I will not be updating, ot replying to this thread anymore as i dont keep myself updates with what going on in the Note 3 world. Luckily, nicholaschum has taken things into his own hands and you an continue the conversation in this thread

Have a nice day, and hope to see you all in the Note 4 forums

Requir rooting only.

First timer here...

I am ONLY interested in rooting my Note 3 (SM-N900W8) KitKat. I would like to keep my current firmware. To that end, can I just ignore everything else but the "CF-ROOT" procedure, outlined below, to root my Note 3 without tripping its e-fuse Knox counter? If I do require YOUR 4.4.2 firmware, then can you tell me what's the difference between the two firmwares? Or better yet, can you tell me where I can download my current firmware so I can re-flash it after this rooting process?

Thank You very much!

PS. Sorry to quote your whole post but I did not want to cause any misunderstandings. I understand that I only have 1 shot at not tripping the Know counter.

Whats different from the other other upgrade threads? This one doesn't block you from going back to 4.3, it allows you to retain knox 0x0 and it's safe.

Just tried this, worked perfectly. I came from X-Note 7.0 and did this on my friends Note 3 and he was on stock. I already had knox 0x1 but i was alble to keep his at 0x0.

As of now, this has only been tested on W8 model as it takes the files from the Telcel firmware (mexico). You can use this method on any W8 model, the only thing you will have to change is substitute my modem (CP) by the modem from the latest 4.3 firmware of your carrier. It seems as the MD5 from all modems for all canadian carriers match exactly, so the model for rogers also applies to Bell and Telus

If you are coming from a non-canadian W8, you can extract your modem directly from stock firmware. Here is how:

Upgrading to Kit Kat and downgrading back to 4.3 does not trip knox, and rooting using my instructions either. Be sure to turn off reactivation lock before flashing this. This method gives you an easy way to official 4.4.2, once you're there, you can flash any 4.4 rom.

Also, and this is an important factor for a lot of people, this doesn't block you from going back to 4.3. If ever you want to go back to Jelly Bean 4.3, just flash back to it via ODIN

Download all the files, PIT, BL, AP. CP and CSC, the flash via ODIN 3.09. Then flash CF-Root and CWM if you wish. I did not check re-partition in ODIN, it worked for both of my Notes, most users didn't check it either, but a small few said the flash failed until they checked re-partition, either way, it should not brick your device.

Here are the links to the files:

PIT: (MD5: e2dba603c963443660b369e04b07d574)

BL: (MD5: 1bce2f5a137901e2fb206379d3e7ae11)

AP: (MD5: 08443eb20702a975fc0be85f7e9c439d)

CSC (this one is for Canada only, if you have any other carrier please download yours):
(MD5: beae61ca1628b303657c40e14cac3fb6)

CP: (MD5: 45522799eb027108fa1c493cbd83abf5)


CF-Root: Don't use included ODIN in CF-Root, use 3.09 and flash via AP

CWM: (MD5: 31e4a86b58837ba87bfa1bf2073371db)


Thanks to Oogar for a more complete version of this process. This method does break WiFi and NFC so head over to his thread for the patch and a proper thanks
