[Q] GT-N7105T - Telstra (Australia) Note 2, stalled during CF-Auto-Root

Hi All,
Just trying to find some people who've managed to root the Australian version of the Note 2 successfully? I have the Telstra Galaxy Note 2 (GT-N7105T) and sat down this afternoon to root using CF-Auto-Root.
I got to the part where the phone is in download mode after pressing the volume up to proceed (other option is to press volume down for exit & reboot). I did not change any settings in Odin, plugged the Note 2 into USB and hit Start in Odin (after selecting the CF-Auto-Root package... everything exactly as the instructions state), then it took a few minutes before it gave the "<ID:0/003> Added!" message. Since then it's been sitting for about an hour at the same screen both on the Note 2 and in Odin... getting a bit worried because Chainfire said this should only take 30 seconds..?!
Current Odin screenshot, it's been about 1 and a half hours now on this screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Hoping some others with rooting experience can help out – did I miss a step? In any case I don't think it's going to progress, so how should I exit out? Hit Reset in Odin? Just unplug the USB cable and try to reboot? Or a hard reset?
Cheers for any advice!

you have used the tar for normal lte version not telstra version.
if you have a nandroid then restore it.
i am not sure if you should or shouldn't disconnect cable of your phone...

Cheers for the reply UtkarshGupta.
I did a bit more research and found that I needn't have been so worried... I thought that maybe it had froze part way through flashing, but the ID:COM shows that it had only just connected with the device and hadn't done anything else! (Of course I only knew this after doing more research on Odin.) Probably because I plugged in the USB then clicked Start in Odin - the PC was still installing drivers and ID:COM wasn't lit up yellow at that stage, soo... it was okay to pull the USB cable, then I just held the power button to exit download mode.
But now the experience has me spooked - not sure if I should try again, or whether I should wait for a Telstra-specific root method that's been tested. After all this variant phone was only released two days ago here in Australia...

I don't believe you have a problem with the ROM. Your problem is that you're running an old version of Odin3.
I received my N7105T the same day as you did and performed the root procedure first thing, using the same ROM as you have but Odin3 v3.04. No problem.
Two things though:
1) Be sure that you've installed the latest Kies to ensure the latest and greatest drivers are running.
2) Make sure after you've installed Kies that it's not running as it will otherwise not allow connection to the COM port established through the USB lead.
You shouldn't have any problems performing the procedure based on this information.

Hey Artstar,
Thanks for the info. After you mentioned the process you used (the same CF Auto Root package) I was more confident that wasn't the problem.
I have just successfully rooted using the same process as previously, except for waiting to be sure that COM was established (yellow COM box), and I also did install Kies for the USB drivers just to be sure (then uninstalled Kies).
The only thing now is that I get a message when trying to use Triangle Away (Play store version), it says "Could not find hidden partition. Are you not using ICS?" How did you get around that? I have not upgraded or done anything to the phone, it's still running Android 4.1.1.

How did you go?
I just got the note 2 LTE as well and want to root it.

Hey shawn, everything is a-okay now as far as the binary count goes... There have since been a couple of updates to Triangle Away and one of them was for compatibility with GT-N7105T (which is the model I have). So I ran Triangle Away and there were no problems there since the update. Although I haven't actually checked the binary count myself... but I got to the stage where I would rather have root, I didn't really care about the counter.
Depending how badly you want to root, you may just want to go ahead. There shouldn't be any problems there (just make sure you use a compatible package/method for your phone). However if you want to still get back to warranty you might want to double-check your exact phone model with some others who've rooted the same phone. (I'm not sure how many different models of LTE Note 2's are out there.)
Hope that helps!

[Q] Bricked, and Broken (mentally)

Hello internet, I'm a noob, so excuse my noobiness. Basically, I've managed to "brick" my SGH-T989D, also known as a Samsung Galaxy S2X, or Hercules; I'm on the Koodo network, and using 4.1.2 which I acquired from Kies. I was attempting to flash TWRP to achieve root using Odin as suggested by this website:
http://www.androidayos.com/2013/04/29/root-t989dtlumc4-samsung-galaxy-sii-sgh-t989d-teluskoodo-jelly-bean-4-1-2/
I followed the instructions, but Odin failed in the middle of the flashing. Now I'm stuck with this screen (not my picture):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
One of the attachments is a screen shot of my "About Device" information from before I was bricked. I've tried flashing multiple stock ROMs through Odin, typically with a name similar to "T989DTLUMC4_T989DOYBMC4_KDO", but it consistently fails. The point at which it fails varies, and I'm not confident about what's causing the failure, but I've noticed it tends to hang up on "<ID:0/003> SetupConnection..", or fails at "<ID:0/003> Complete(Write) operation failed.". I'll attach a screenshot of what Odin looks like upon failure with the message box clearly visible. I don't have any recovery files, because, ironically, I was bricked while flashing a recovery to prevent bricking. Also, I'm open to trying things other than Odin.
I'd like assistance to get my phone back to a usable state (at least able to make calls, and text). I would be especially grateful if it ended up rooted, and/or with a safe method of flashing, and trying custom ROMs (I eventually wanted to have Cyanogen mod 10.1, and Clockworkmod Recovery). However, any help is appreciated; Thank you for your time.

You need to search for ODIN version 1.85... hard to tell what you're using but it looks very different from mine. ill try to attach a good copy of it. The one i used was nice.
In the mean time... have you gone into Kies and at the top select "tools" and "emergency recovery" or somethign similar to those words? that WILL restore your device to a usable state... that's guaranteed.

Hey! thanks for the reply. I was using Odin v3.07. I have a couple of screenshots for you. Kies wants me to provide a recovery code (screenshot), which is not given to me. I believe that option only works if your phone was bricked while updating using Kies. Also, Kies doesn't seem to be connecting to my phone. It never advances from the connecting screen (screenshot), and seems to give up when I navigate to different menus. This is probably due to the current state of my phone. Lastly, I downloaded Odin v1.85, but the flashing failed with a similar error (screenshot). I hope you have more ideas.

IT WORKED!! (screenshot) I don't know what's changed since the last time I tried it; why is Odin so inconsistent? Regardless, thank you to Droid8Apple, and XDA forums. There is a lot for me to learn in unlocking the potential of my android device.

You have to make sure Kies is disabled before using Odin, it'll cause Odin to either not recognise or fail.

Thank you for the advice; I'll certainly remember that. By disabled do you mean simply closed (clicking the red "X" at the top right), or is there something further I need to do like kill processes in the task manager, for example?

How do i find out if the phone is rooted or not?

Hey everyone i have a telus samsung s3 and it wouldnt accept the unlock code so the guy who i bought the unlock code from said my phone might be rooted and i need to unroot it?
Heres the information from about device:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I also installed this app called "Root Checker" which shows if the device is rooted or not and heres the result:
According to this website: http://www.mobile-spy.com/blog/is-my-phone-rooted/. I downloaded an app called "Terminal" and followed the instructions:
Another simple way to find out is to download and install a “terminal” client on the phone. A “terminal” is a text-based window that allows us to run commands on Linux devices such as an Android phone or tablet. It is the command line interface for Linux, similar to DOS.
Upon opening the terminal, if you see a “#”, then the phone has root access and is in superuser mode.
If when opening the terminal you see a “$” then the phone is not in superuser mode, but that doesn’t mean that it has not been rooted.
Type “date” and press enter. It should display the date and time. If the date does not display, then the terminal doesn’t work, try downloading another terminal client.
Otherwise, type “su” without the quotes. If the device has been rooted, the next line will display a “#” signifying that you have root access and the device is ready for superuser commands. If it has not been rooted, then the terminal will not recognize the “su” command.

Here are the results:
As you can see it verifies that the phone isnt rooted so please tell me if there is some other way to verify or just those apps?

try another root checking app?
install an app that requires root and see if it works/asks for super user permission?

Never had a problem using root checker or the su command. Your phone is not rooted (unless someone tried to and then half-assed it maybe).

No, but your best bet to get the phone completely back to stock is to use Odin. Search "Odin back to stock". Pretty easy to do just need a computer and about 5 minutes.

That should be the right rom. Have you gone into recovery, wipe the phone and retry flash the stock rom? A reformat? i was having lots of trouble with mine but seen this today and tried method 2 with the exception of gapps to get it back to stock.

You running a 4.3 bootloader? Is your phone an i747 or i747m?

Cannot do anything with Galaxy S3

I cannot root it, I cannot install any recovery besides the stock one that comes with it, I cannot get it to connect to the computer as mass storage, only as a media device.
Im thinking I just blew $215 on a paperweight.
I CANNOT EVEN INSTALL TITANIUM BACKUP TO GET RID OF THE FREAKING ATT CRAP!
What have I did wrong?
I have CWM v5.5.0.3!
Ive tried countless number of rooting programs including some poplular ones:
1. Casual - http://forum.xda-developers.com/showthread.php?t=2189536
2. Kingo Android ROOT - http://www.kingoapp.com/android-root.htm
3. Towelroot - https://towelroot.com/
4. CF Root (Flashed SU but does not work) - http://download.chainfire.eu/269/CF-Root/CF-Auto-Root/CF-Auto-Root-d2can-d2vl-sghi747m.zip
CF Root flashed Superuser but it says unfortunately Superuser has stopped.
Im about to take this back to the store I got it from....

Tell us your phone's specifics (firmware, modem, bootloader, is it AT&T or some other carrier). Does the phone work OK otherwise?
Do you have a ROM you want to try?

How are you flashing the recovery? Do you have Knox on your phone?

The fact that you can get to download mode is good. But sorry, what this means is out of my league. Try PM'ing "DocHoliday77". He seems to be a great resource for all things SGS3. He's in numerous threads in the Development forum
EDIT: I booted into download and mine says the exact same thing

You have Knox on your phone. You tripped the knox counter and changed the warranty bit to 1 which means the warranty on your phone has been voided.
When flashing a custom recovery phone in Odin, do not check auto reboot. When you see the word reset appear in the status window, remove the usb cable, pull the battery, and use the button combo to boot inter recovery.

No still nothing.
It vibrates when you first start it up and then the Samsung logo comes up with Recovery is starting in blue at the top for about a second and then goes to a black screen and nothing never happens afterwards.
What is Knox by the way? Is this keeping my phone from being rooted?

Figured id post here now rather than having two threads going for the same problem.
The more this goes on though, the more i am suspecting some sort of hardware problem.
I want to suggest using the PIT file to repartition the device, but theres no firmware to use along side it. Theres a program here on xda called PIT Magic i think. I dont know much about it, but maybe it could help you to somehow repartition....?
As for knox, there is tons of info out there on it already,so i wont get into it here. It wont block you from rooting, but it can deny root access when an app requests it.

Will the pit wipe it?
Will installing cm 11 using the installer work? Does it work?

Yes, repartitioning will wipe your data.
I dont use CM roms so im not familiar with the installer. Sorry.

Im out of ideas for you...sorry. I kinda think its probably a hardware issue. It sounds like youve done everything you can to get root or recovery. Might be wise to start looking into a motherboard replacement...and keep your backups up to date!

I just spent $215 on this. I don't think the place where I bought it from will ever take it back.

I wish i had something better for you to try. Sorry.
If you are willing and able to consider it, i saw several motherboards and devices with broken screens (but otherwise functional) go for less than $65 today. Its the best option i can think of now.

Where at?

Sorry. It was on ebay. They often will go for a bit more than that, but if you are patient you should be able to get one relatively cheap.
Just do not buy any that say no power. Just look at ones that are a good motherboard, or a device with a broken screen where they say it powers on, just with no display. Also make sure the IMEI is clean.
Good luck!

Try using FlashFire, it's basically Odin for your phone. I think you have to join the Google+ Community to download it, but it works great.

Once you update to the latest firmware, towelroot will not work. The exploit towelroot uses has been patched. And no one knows what you mean by "modstrings"

Well it don't work now anyway and forget the modstrings part I just need a way at this point to root and I cab roll with what I need to do worst case I have to go buy a new computer but I would rather not

https://towelroot.com/modstrings.html
This would make a great t-shirt!..."Modstrings? What are you talking about?"
Yes he is right the latest update patches the towelroot exploit. But you can still use another method without computer. But basically if you want your whole world to open up then you will not need that update. For example im running 5.1 lollipop on my gs3 so that ota update is not helping me at all. Rooting your stock rom opens a couple door in an old phone. But installing a custom rom, kernel, mod, framework, etc. will open every door. My gs3 outperforms my sisters gs6 in many ways and i had 5.1 update before she did. Amd i can always put my phone back to stock rom, unroot, and make it under warranty terms again because i made backup. But if you want slight upgrade i can help you troubleshoot the ota installation. But if not its ok because my wife has same phone and didnt update and she is running same custom rom, kernel, mod, framework, etc that i am with no problems.
Check out this thread i started last night as its related and has more info...

Fastest path to cwm is rooting your phone using towelroot or cf autoroot then install root checker app to verify root and then install app supersu and then install app called rommanager from app store and update the recovery in the app. Should only take a few minutes plus reboot time. No computer needed. Forget about the ota upgrade for now since you want cm12.1. Once cwm running do a nandroid backup so you have a stock rom image before doing anything else. Later you can revert back to the moment after you rooted if you run into any problems and try again, try ota update again, or unroot and get it back to warrantied state. Before updating to custom rom check out my new thread to get some ideas on what to back up to save your important data and other ideas. Yes i can help you furthur just message me anytime or ask in my thread..

The towelroot saying success is throwing me off. I will try to find out info on that. Did you use root checker app to verify root or no root? My first root i thought nothing happened at first. Let me know

Error 7 first exploit and error 9 secong exploit.... as for towel root years ago I paid for root checker advanced I know better its not rooted I have done factory resets and tried again I'm running 4.1.2 this is stock from a ota a long time ago I know you have no reason to hekp but if you can get me in the right place to make this work you save me a grand plus if I'm getting a new pc its asus gaming level what I had was 6k I won't take much less please let me know what you find I have been reserching for the last six hours.... no luck

Thanks to zip addict he found me king root and I looked in to it the 4.5 version I git root no pc all is needed after that is super sume from what he told me so that you can install the right super user and move on to a recovery now at this time I'm trying to find a dl for super sume that is not the play store as it says not compatible
