Problem with rooting and flashing with Odin.

Hey folks,
This is the first time I have had a Samsung phone and I am unfamiliar with Odin, I finally decided to root after having had my phone since release ( the first time I have had a device and NOT rooted it on day one!). I've used the Odin bundled with Chainfires CF-Auto-Root, 'CF-Auto-Root-hlte-hltexx-smn9005.tar.md5'.
This is what I get from Odin after flashing -

You can either take your battery out and try and boot up again, but more likely You need to Reflash 4.4.2 and re-root, - seems the bootloader isn't playing too nice with everyone currently.

Do we have a repository for ROMs? I assume I flash a ROM the same way I 'rooted'?

JB, I'm with Vodafone UK, they have yet to roll out an OTA for KK.

My bad on the last post saying to reflash 4.4.2 - seems everyone is using Odin right now and having issues with something.
Head over to Sammobile.com and grab the lastest JB Rom for your device, type in *#1234# and post your results here and we can tell you which firmware you need to grab,

That file you used was recently updated by chainfire to work with Kit Kat. Could it be something in there kept you bootlooping?
I have a copy of the old file that was used to root JB. If you want I'll upload it somewhere for you to try. Same process only different file.

Do you think it's because I am rooting with a KK kernel on a JB ROM?

Take your battery out to kill the power, then it'll let you go back to download mode when it's powered off.
hey_joe is correct with the fact you seem to have used the wrong CF file which is for 4.4 and doesn't seem to work with 4.3 builds.

It'll go back to download mode just fine, but what do I flash to restore my ROM? Is there an older 4.3 file I can flash to recover my phone?

No. As I said Chainfire updated the file to work with Kit Kat and maybe something from that update is causing the bootloop. Because he can't downgrade his phone's firmware to JB, he probably couldn't test if there was an issue or not with JB using the new file. Anyway it's just my thought. You can try the old file and see if it works. It beats having to download the whole firmware and flashing all over again.

What bootloader are you on currently? type *#1234# in your dial pad and I can send you the right way for your ROM - dejmbay has pre-rooted and stock roms listed in the dev section here.

F*&K me, I am half asleep this afternoon, IT should have said You're on the Vodafone UK which is MJ6 - for the correct AutoRoot use the link hey_joe gave you.
If no good, have a look here or here second link has Pre-rooted ROMS

I'm using some unfamiliar recovery now, 'Android system recovery <3e>'. Looks basic. I have root though, am I free to flash via storage a ROM now? I assume I do exactly the same flash via Odin to install TWRC?

You will need a custom recovery, You can try either Chenglu's CWM, PhilZ CWM or TWRP - all three are easy to use, quite easy to install also -- Open ODIN, flash in PDA and after 10secs or so all done, have a look around at the ROM's there's some nice one's going

Odin won't flash Disk Image Files? Only Tarballs? Chenglu's 6.0.4.5. CWM is an image not a tarball.

[Q] Big problem root gt-i9505

Hello,
*
I come to you because it has been more than 24 hours that I try to install an AOSP rom in my s4 Galaxy (GT-I9505)
In fact I have a big concern when I flash CF-Root-jflte Self-jfltexx-gti9505.zip (latest site chainefire) with odin everything goes correctly
But once back in android, not Rooted (lack binary ...)
-I tried several version odin (1.85, 3.04, 3.07 and 3.09)
-I tried on several PCs (Windows 7 and Windows 8)
-I tried several USB cables
-I made full wipe
-I flashed the PIT file from the stock rom 4.4.2 (version in my S4)
-I tried to put everything back to zero with a stock rom
*
Without success, my phone does not want to be Root ...
*
So I thought I flashed a Recovery
I tried TWRP, CWM and Philz-recovery and reboot before all began to flash, so do not even touch system
I tried several rom AOSP (11 cm, slimkat ...)
*
Could you please give me a little help here because I dry supplement
I'm bored here, this is my 5th as samsung and this is the first where I can not install CM 11
I do not understand why not traveling on wheels Recovery flash, they do not put error message but reboot alone and without flash
*
Ps: I've tried stock rom pre-Rooted to fasher with odin, it works, I have root but it does not address the concern of recovery
Sorry very bad English, it's google traduction

Are you sure you're using i9505? I have the same device and haven't any issue and the chainfire auto-root works very well for me.
Good luck. :fingers-crossed:

Yes it's a GT-I9505
I flash I9505XXUFNC4_I9505OXXFNC3_I9505XXUFNC4_HOME.tar
This works fine, but I can not root.
CWM and still does not work, it restarts before flashing the rom without I touch the button

Strange.
Try flash again the stock rom and use the Odin from chainfire auto-root. I'm doing this every time and work very well without any issue and fails.
That's all I can help you, good luck man.

Ok, follow these steps. Ignore anyone, if you have already done.
That's what I do and usually gives everything well.
Flash samsung stock rom, after reboot, open Supersu disable Knox, Turn device off, turn the divce on in download mode, flash the custom recovery (Philz or TWRP recommended).
Have you try this?

Yes, but it does not work.
Even after having root Supersu said that lack binary files.
Knox did not disable beings on my phone
I do not know what to do now
I'll try:

PDA: XXUFNC9
PHONE: XXUFNC9
CSC: OXAFNB8 (8 codes)(NOTE: KIES will NOT recognize this FW due to CSC mismatch..)
Kernel: 3.4.0-481100 (19.03)
KNOX WARRANTY VOID - 0x1!!!
Build Date: 19.03.2014
Changelist: 481100
Original Stock ROM: Download: <<< Sammobile.com >>>
Pre-Rooted ROM (Odex): Downloads: <<< AFH >>>
Latest KNOX Bootloader INCLUDED - Completely IRREVERSIBLE back to 4.3 & 4.2.2!!!
It is Knox free
Edit :
This still does not work with the Knox free.
Tomorrow I back to the store to get a refund, I'm tired.

Why not just flash a stock rooted rom, and go from there. If it's the GPE there is a rooted ROM that fits that phone. That's what I did.
http://forum.xda-developers.com/showthread.php?t=2569510
That's the ROM I used.
Nevermind I noticed that you have the I9505 and not the I9505G.

[SUPPORT THREAD] Canadian N900W8 KNOX 0x0 Status {Updated April 5th 2015}

Important Information
List of ROMs installable on the SM-N900W8 (by Model number): Here
Current Firmware: N900W8VLU2DOC4 - Download
Status: VULNERABLE
Latest Recommended Modem (LP): N900W8VLU2DOC4
Previous Recommended Modem (KK): N900W8VLUCNI1
Flashing a Modem:
If you have an invulnerable bootloader, you can flash any of the latest modems through Odin no problem, download and flash under CP.​If the modem does not stick after flashing:
Flash it without Auto-reboot ticked.
Manually turn off your phone (battery pull required), then immediately go back into Download Mode.
Flash it again, then manually reboot the phone (battery pull again) after done.​
GPS Problems Fix (Not Locking): Here by @crom1.
Thanks @Calen77 for the find!​
Vulnerable: Trippable
Invulnerable: Untrippable under any circumstances while running the bootloader loaded phone. Odin flashing friendly.
Semi-invulnerable: Trippable under one condition (can be ignored if you don't plan to downgrade). Otherwise they are all untrippable.
All 4.3 N900W8 bootloaders are normal bootloaders and will trip when it detects any modification.
All 4.4.2 N900W8 bootloaders are unable to be tripped when doing just rooting and installing custom recovery.
-> The leaked Mexican bootloader allows you to avoid tripping the bootloader even through a downgrade of 4.4.2 to 4.3.
-> Canadian 4.4.2 bootloaders will trip if you attempt any downgrade to 4.3. This is the only issue.
-> You can flash a different modem, a different ROM base (AOSP or TW), CSC, Kernel, Recovery and NOT trip KNOX on any devices.

Currently known N900W8 4.3 vulnerable bootloaders: MI5, MJ1, MJ4
Currently known N900W8 4.4.2 invulnerable bootloaders: MEXICAN NA2
Currently known N900W8 4.4.2 semi-invulnerable bootloaders: NB7
Currently known N900W8 5.0 vulnerable bootloaders: DOC4
For the people running MI5, MJ1 vulnerable bootloaders (excluding MJ4) and not willing to upgrade to 4.4.2 -> I suggest using URDLV to root without tripping KNOX: http://forum.xda-developers.com/showthread.php?p=46818375
For the people running MJ4 vulnerable bootloader and not willing to upgrade to 4.4.2 -> You can use Kingo root to root, however this is a fondly avoided app, as the first version sent your IMEI to a server in China. Hesitant to upgrade to 4.4.2? You're done.
For the people running MJ4 vulnerable bootloader -> I suggest following the guide below this Q&A to get your phone to 4.4.2, so you get the Mexican bootloader to be free of all KNOX and it's dread. (Highly recommended)
For the people running NB7 semi-invulnerable bootloader -> You are free to root, custom ROM flash, replace your kernel, modem updating through Odin, etc. Just do not attempt to downgrade if you want to preserve KNOX.
Q: But but but, what if I.....
A: NA2 bootloader? Nothing you do can touch your bootloader UNLESS you intentionally upgrade your phone through KIES or Odin. These are the only two tools that is able to touch your bootloader. Everything you do will preserve KNOX. The hierarchy of your phone stands so that the bootloader is on top of the recovery partition, and everything else is under recovery. Recovery is unable to touch the Bootloader (like how a normal office worker can't fire their boss).
Q: How about.....
A: NA2 bootloader? You are safe. Stop worrying about sh*t.
Q: How does this work?
A: The Mexican NA2 was a leaked firmware for the N900W8 intended for development devices, it was never released in the "NA#"'s officially for the N900W8 models. (Need confirmation if tripped KNOX on the Mexican version of N900W8) This could mean they turned off the functionality of the security breach on these devices while trying to distinguish the two different N900W8's modems so they don't trip everyone's KNOX when the OTA is released. In layman's terms, the Mexican firmware was the base for the Canadian version, but when applying different patches to distinguish the two regions, they needed a development version that doesn't trip KNOX. The latest NB7 was not patched most probably due to either not noticing this flaw or slow updates as usual (very, very slow).
Q: How do I check my bootloader version?
A: Using @vndnguyen's app on the play store, located here. Look under Firmware Info (in green), and then under Bootloader version. Take the last three characters for the actual bootloader version.

My guide to get any Canadian Note 3 on 4.3 to 4.4.2 safely without tripping KNOX
Credits will also go to @Oogar and @polish_pat for the tutorials and their original files!
This is my version of @Oogar's and @polish_pat's guides, and I will keep them up to date. What's the difference? Well I will keep the links as fresh as possible and mirroring them as I see fit.
I will also provide pictures so that you will be assured you are doing the correct thing.​
Step 0: Verify your BOOTLOADER version
If your bootloader is of version MI5, MJ1 or MJ4, move onto the next step. Click the button below for a brief instruction how to check.
If your bootloader is of version NA2 (somehow) or NB7, skip to the contents of Step 4, however you won't be on a "happy" (invulnerable) bootloader if you are on NB7.
Using @vndnguyen's app on the play store, located here. Look under Firmware Info (in green), and then under Bootloader version. Take the last three characters for the actual bootloader version.
Step 1: Download these files!
Odin v3.09 - Fast Link
Samsung Kies (for drivers) - Direct Link -- Official Samsung Link
PIT File: (PIT) HLTE_CAN_OPEN.pit
BL File: BL_N900W8UBUCNA2_336994_REV03_user_low_noship_MULTI_CERT.tar.md5
AP File: AP_N900W8UBUCNA2_336994_REV03_user_low_noship_MULTI_CERT.tar.md5
CP File: (CP) Rogers Modem.tar
CSC File: (CSC) Canadian Multi CSC.tar
Step 2: I am on MI5/MJ1/MJ4!
NOTE: This will erase all your data from your phone as you will be flashing a LEAKED firmware. Official ROMs do not wipe your data. Make sure you make a backup.
Install Kies, then reboot your computer. (Do not open Kies, it will affect Odin!)
Extract Odin3 on your desktop using WinRAR or 7zip.
Open up "Odin3 v3.09.exe"
Turn off your phone and hold the HOME BUTTON + VOLUME DOWN + POWER BUTTON until you see a warning -> Press Down to Continue.
Plug in your phone using the original USB 3.0 cable (highly recommended)
Step 2 complete! Move onto the next step if you succeeded. If not, try restarting your computer.
Step 3: Odin's opened, device detected!
Make sure your Odin looks exactly like this (as shown in the photo below) with all the defaulted values. Do not tick anything unnecessary that is not mentioned in the photo. If your Odin looks EXACTLY like the photo I showed, move onto the next step (excluding ID:COM values).
Now add in the files you downloaded above according to their bracket names. Make sure that you UNCHECK Re-partition once all the files are set.
Click start and wait for the process to finish!
NOTE: If you can't boot up normally, retry the process above but check Re-Partition in Odin instead.
Step 4: You are now on the famous N900W8 "happy" (invulnerable) bootloader!
If you just want to obtain root and custom recovery, move on to Step 5 and finish there.
If you want to flash ROMs, move on to Step 6. (NOTE: Yes you can follow Step 6 after Step 5, but if you plan to flash ROMs at the start, you don't have to root your current ROM.)
Step 5: I'm not going to flash ROMs, I just need root and custom recovery....
Download ChainFire's CF-Auto Root: Direct from Chainfire's Website
Download the latest TWRP for N900W8: Nicholas' Database or TWRP Server (Slower)
Turn off your phone and hold the HOME BUTTON + VOLUME DOWN + POWER BUTTON until you see a warning -> Press Down to Continue.
Extract "CF-Auto-Root-hlte-hltexx-smn9005.zip" to a specified folder and ONLY touch the .md5 file, DO NOT TOUCH ANY OTHER FILES.
In Odin's AP area, select "CF-Auto-Root-hlte-hltexx-smn9005.tar.md5"
Click Start
Once it is complete, let your phone fully boot into the lockscreen, the put it in Download Mode again.
In Odin, press Reset, then In Odin's AP area, select "openrecovery-twrp-2.8.3.0-hltecan-4.4.img.tar"
Click Start
Once it is complete, take a Nandroid backup and you have finished this guide! DO NOT PROGRESS FURTHER UNLESS YOU WANT TO FLASH ROMs.
If you can't write to your SD card, follow this guide by @Khizar: http://forum.xda-developers.com/showthread.php?t=2684384

NOTE: YOU WILL NEED AN EXTERNAL SD CARD FOR THIS AS MOST ROMS WIPE YOUR INTERNAL, MEANING YOU LOSE YOUR INSTALLER PACKAGE WHILE THE AROMA INSTALLER AUTOWIPES, AND THE INSTALL WILL CORRUPT.
Download the latest TWRP for N900W8: TWRP Server
Turn off your phone and hold the HOME BUTTON + VOLUME DOWN + POWER BUTTON until you see a warning -> Press Up to Continue.
In Odin, press Reset, then In Odin's AP area, select "openrecovery-twrp-2.8.3.0-hltecan-4.4.img.tar"
Click Start
Once it is complete, take a Nandroid backup of your current ROM.
Boot into your current ROM and take the Nandroid backup out of your phone's internal storage, and move it into your external SD. [URGENT]
Put your custom ROM you desire into your external SD, in this guide I will be guiding for an N9005 ROM.
Put your custom Kernel you desire into your external SD, you will need an N900T kernel [IMPORTANT, ANY STOCK N9005 KERNEL WILL BREAK WIFI/NFC FUNCTIONALITY] (If AOSP OR S5 ROM, skip this step)
Put this NFC/Wifi/BT fix into your external SD: N900W8 KK WIFI-NFC Fix (NI1 Source).zip -- Thanks a lot @Oogar for the file. (If AOSP OR S5 ROM, skip this step)
Turn off your phone and hold the HOME BUTTON + VOLUME UP + POWER BUTTON until you see "RECOVERY BOOTING..."
Install the three files in this procedure:
Wipe /system, wipe /data, wipe /cache, wipe /dalvik-cache,
FLASH CUSTOM ROM → FLASH N900T KERNEL (SKIP IF AOSP OR S5) → FLASH NFC/WIFI/BT FIX (SKIP IF AOSP OR S5)
Boot up and enjoy! If you have any problems follow this link: http://forum.xda-developers.com/showthread.php?t=2657214

All of this makes alot of sense.
Yesterday I tried flashing the Mexican files, but I was unable to flash over the bootloader. It kept on giving me an error saying auth fail.
I decided to simply flash the AP file, and then the chainfire root file and of course the recovery.
I am now running Xnote without any issues as of yet. I will mention that I didn't have WIFI after booting up, but I installed lean kernel and all is happy now.
Thank you for your informative post.
B.T.W.... knox says 0x0 but it says custom.

Thanks for the info nicholas.

His was like @Oogar's thread, informative instructions to GET 0x0, but it's not an updating thread that tells you which firmwares are KNOX exploitable, through the different Canadian firmwares
My thread is to inform people about the latest firmwares that are affectable/non-affectable by KNOX, not teaching people how to get KNOX 0x0. This means I will update this thread whenever there's a new Canadian firmware so that the Canadians will know whether it is safe to update to the latest iteration of updates.

NC1 is a Mexico firmware. Meaning you're running on the Mexican version of the N900W8.
If you're running the Mexican N900W8 then sorry, it isn't.
If you're running a Canadian N900W8 with the NC1 firmware, with NA2 or NB7 bootloader, then yes, it is safe.

I'm still alive and well, just no time at all to update. I'm even running stock Rogers right now -_-.
As polish_pat said, feel free to use anything in my thread as I lost track and don't want to update the OP while being uninformed.

You should be able to change your modem. Just flash in Odin. Will not trip KNOX {CONFIRMED BY ME - updated from MJ4 modem to NB7}

Will the Mexican NC1 modem work in Canada, or should I stick with NB7? I'm in a basement, so I'd like to try a different/better/newer modem.

Always use the latest from your region - my code.There's nothing better than what you're meant to be using on your device made for your region.

Actually it does matter. Strange how you got it working.
As the newer version has specific changes for the international variant, it won't matter to you as the Canadian version won't need the new fixes that the international variant needs.
I would just flash the hltecan version through recovery, like an update.

first time using Odin to root.
If I am already on version 4.4.2 and NB7 do i just use step 5 to root, or will I still need to do step 0?

As stated on Step 1, if you're already on NB7 you only need to skip to Step 5

Soft bricked, can't find stock roms, it's been 18 hours, I'm slowly losing my mind...

SM-N910G, I flashed chainfire's auto root without first using the Dr K/PhilZ forced/submissive whatever kernel first.
I can't seem to find a normal stock rom to push through Odin without encountering a sea of dodgy download sites.
Can anyone help? Just want a 5.1.1 stock rom...
Even any of the other 5.1.1 builds like Simpl, I can't seem to find a tar file.
Any nudges in the right direction would be very handy.
Thanks in advance.

If you want to return to stock.
Download Samfirm from here: http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Then extract the files and run the tool.
Then enter the model as SM-N910G and the region you are in (CSC)
Then tick the 'Auto' box and press 'Check Update' and the 'Decrypt automatically'
It should look something like this, I put INS which is for India.

Then extract the firmware from the downloaded file using an archive tool such as Winrar and flash it via Odin.
Or use Sammobile.
If you want to install a custom ROM you will need to flash a custom recovery, for the N910G I would recommend this one (TWRP 2.8.7.0):
Download the twrp-2.8.7.0-trltedt.img.tar
https://dl.twrp.me/trltedt/
Flash it using Odin and your phone in download mode.

download stock firmware from sammobile (google it) and flash it with ODIN.

Unless you do not care about downgrading to lower bootloaders. It works fine otherwise. But having it locked does suck if you want to downgrade. No way to do it..... Yet.

Thanks for the help fellas, I ended up finding "N910GDTU1COJ3" which I'm flashing with Odin now.
Next time I'll flash the Dr K kernel before I do anything else...

Check PM.

There seems to be some confusion here, people are telling me, even on other threads, to do a factory reset in the stock recovery tool.
There might be an issue with recovery then, because I've only got a green android logo with "Downloading..." on the screen, nothing else is available to me.
It's not like previous bootloaders I've used where you use the volume key to select options etc, I literally can't do anything except flash from Odin.
Yes I have tried to flash TWRP using Odin, it didn't work...

OMG... By random luck I decided to hold the volume up key instead of down key when powering on and hey presto I have TWRP...
36 hours of my life I want back!

Not unless, someone upgrade and then try to downgrade

OK, dumb question. I've rooted devices, put custom ROMs on them, wiped them, etc. all before. But one thing I'm not sure about.
If I flash this EPJ2 using Odin, would that wipe out all my apps and settings? Or would I only lose root until I re-root?
Just wondering if I should plan on backing everything up. Thanks.

I took the plunge from maximum overdrive, phone feels smoother than before.

As, I said any TW MM will work. If you install EPJ2 on top of another ROM, you will obviously lose customization.
If you need to go back to OD, you would need to Wipe your ROM and install OD through TWRP recovery.

My experience is that you can downgrade from the MM Series of T-Mobile Firmware BLs and Modems.
For example, I was successfully able to switch between DOK2, EPE3 and EPJ2 using Odin 3.11.1.
I'll include just the Bootloader (BL) and Modem (CP) Odin files in case anyone wants 'em, as I usually find them in a post somewhere down the line on the official firmware comments.

Quickie Instructions I have on a notepad file along with these files on my SD Card for reference.
Found it on some forum or site that was real helpful!
INSTALLING THESE FILES
1. Load phone in download mode. (Vol down+Home+Power)
2. Open ODIN3 on your computer. (Make sure the Samsung drivers are installed, you can install KIES to get these.)
3. Load the bootloader file in BL.
3a. Load the modem file in CP.
4. Hit the start button, and let the files flash.
5. If there are no error messages in the log portion of ODIN3, then you have successfully flashed and upgraded to the bootloader/modem.
Note: You can check this in your "Settings - About Phone" section.

Quickie Instructions I have on a notepad file along with these files on my SD Card for reference.
Found it on some forum or site that was real helpful!
INSTALLING THESE FILES
1. Load phone in download mode. (Vol down+Home+Power)
2. Open ODIN3 on your computer. (Make sure the Samsung drivers are installed, you can install KIES to get these.)
3. Load the bootloader file in BL.
3a. Load the modem file in CP.
4. Hit the start button, and let the files flash.
5. If there are no error messages in the log portion of ODIN3, then you have successfully flashed and upgraded to the bootloader/modem.
Note: You can check this in your "Settings - About Phone" section.
Here's a screenie from my CM 12.1 flashed phone.
