Hi and thanks a bunch for the reply....
the battery reset part didin't work...I have tried the method you mentioned the easy method...where you push the CWM recovery file to the device through ODIN...now I hvae the CWM based recovery v6.0.1.4, I have factory reset the devvice through CWM as well and rebooted the phone through there..but still stuck on samsung logo..I think the phone doesn't have any ROM to boot from...I have the stock .tar file for this phone but how should I send it to phone? CWM says to 'install .zip/update file" from external sd card...
my stock file is .tar and it has boot.img inside...also if anyone know a place where I can find my ROM, please tell me that as well....
please tell me what should I do now...waiting for your reply...

Dude just use the emergency recovery vie kies, return to stock.
If possible. Save all cwm files to computer. If you were smart you made a backup image to you ext sd or recovery image we.
Gonna be a huge file be about ten min to save to pc.
Save the entire cwm folder. Yes everything .
Save to your pc.
Use kies emergency recovery.
Re root phone.
Install cwm recovery.
Make a recovery img.(jic you f.u. again lol)
Now put ext sd card in phone
Boot to recovery and try the recovery images again.
If nothing else your phone should be back to stock.
Worked for my gs3.

Do exactly as I say.
Download a sock rom from here. Link:-http://forum.xda-developers.com/showthread.php?t=1896696&highlight=cf+autoroot
After downloading go into donwload mode by pressing volume down+home button+ power key(in this order)
Connect phone via USB and open ODIN.
VIa the PDA option browse to the stock rom you downloaded and click Start and then wait till the rom is flashed. This should do it,
After flashing download this for rooting and extract the file to tar

On a more serious note, i have the International version of Note 2 so dont know much about other variants.
Sorry

There are 2 variants of the Note 2. GT7100 and GT7105. Which one do you have exactly? Go into settings, about device, and Model number....
After you determine which one you have, unless it is a carrier specific one from America, just flash the stock gt7105 one or the gt7100 one from here...

Yo dude sorry I misunderstood what you said, for w/e reason i thought your recovery was borked and not that you were bricked.
SO listen first off dont be afraid of using odin, its not rocket science and you wont bork it up anymore than it already is.
out of curiosity do you happen to use rom manager?
IF so ditch that pos ap, and just stick with recovery like the cwm or twrp.
i found this for you and hope it helps you out.
keep searching and trying dont give up youll get it eventually.
http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unrootunbrick-galaxy-note-2-with-stock-firmware/
basically what the poster above me said, you're only going to be able to do recovery via odin.
its not a big deal just follow instructions.
hope the link helps.

Note 2 stuck at Start Up screen. Please help

My Galaxy Note 2 is stuck at the Start up screen screen. Where its an all black bg and simply says Samsung Galaxy Note II
I have tried using recovery mode, cleared cache, and reset to factory. Neither troubleshoot method worked.
I have tried numerous Odin autoroots. none work. Whenever I try to root it fails. Im guessing it might be because I dont have Dev Debug enable and I cant get into my phone to enable it. because of this issue
I have tried looking for TWRP .tar but every file I download the file is always a .img
The Model of the phone is a SGH-T889 (T-mobile Note II)
I am all out of ideas, and I dont know what to do. I have been search for answers for hours and everytime I think I found a solution it doesnt work.

What ROM was your phone on when this happened ?
Can you get int to download mode ? If yes try flashing stock ROM and see if it helps.

It was on the offical default rom. the phone was never modded, or rooted.
My niece downloads a bunch of kiddie games onto the phone, we constantly have to uninstall them. My thoughts and the T-mobile tech suspects that it the crash may have been caused my too many updates or a bad updated file most likely due to the games or game.
I can get the phone into download mode, and recovery mode.
In reovery mode I have 6 options
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cashe partition
apply update from cache
I have tried Apply update from cache, Wipe cache partition, then Wipe data.factory reset. I also attempted to put a CF auto root .md5 file and a KIES .md5 file which I believe is a stock firmware file on a SD card. to try to use the apply update from external storage option, but neither file showed up when I went into the option. So I guess I didnt have the right sort of file.
So recovery didnt work so I tried using Odin v3.07 and Odin v3.09 with CF auto root files for the SGH-T889, that didnt work, ecerytime I tried to apply it, It was always Fail within seconds. I tried other root files that are made for other versions of the Galaxt Note 2 like the GT-N1700 but those also simply failed.
I tried using what I believe to be stock frimware files with Odin. and those also Failed.
Im not exactly the best person with these. I learn mostly what I know from the internet and reading various forums, youtube videos, and other people experiences. I cannot find anyone who's problem has not yet been fixed through the above methods. so I really dont know where to go from here.
I think the reason I cant Flash from PC is because it might be possible USB Debugging is not enabled. Not sure if this is what is causing all the Fails in odin

Lets see if we can get this resolved.
1) Do you remember what version of Android the phone was on 4.3 or 4.1.2 ?
2) Put your phone in download mode then connect to your computer via usb. Start Odin in admin mode (right click and run as admin).
3) Now do you see ID:COM section turn blue ? Under message you can see "Added!". If you see this then phone is recognized by Odin.
4) If your phone was on 4.3 then download this most up to date firmware - from here http://www.sammobile.com/firmwares/download/22863/T889UVUCMK7_T889TMBCMK7_TMB/
5) Once downloaded, extract the file(use 7zip or winrar), once extracted you will see a file with .md5 extension.
6) Now going back to ODIN, click on PDA and then browse to this file which you just extracted.
7) This takes some time, once done you should see a message like "Checking MD5 finished successfully", "Leave CS".
8) You can leave Auto reboot and F-reset time checked.
9) Now click Start and let the process finish.
10) If everything goes fine you should see a green message "Pass"
Let me know how it goes.

I have the same problem as the OP (boots only up to Samsung logo with black bg) but it was not caused by niece downloading games but instead from trying to install jedi masterx2 rom.
I did what ciphercodes recommended and put phone in download mode and odin went through the motions of installing the stock os (in my case version 4.3) but after apparently installing the rom it again booted up to Samsung note II logo in black bg.
luckily I can install either Clockword mod recovery v6.0.4.3 or teamwin v2.8.6.0
The clockword mod recovery can read the external sd card (whereas funnily enough the teamwin can't) and I can attempt recovery from previous backups on cmr or to install a rom from zip file but neither of these work - reboots again to Samsung logo in black background after apparently installing the rom.
both teamwin and cwr mention that they can't mount system and that's probably why no rom is install either using cwr or odin so my guess is that I have to reformat the partitions cause probably efs file is corrupt but I don't know how to do that and I have done extensive search in google but have not found a solution
so ciphercodes if you or anyone reading this can help please reply to this message

I am uncertain of which version the phone was on. If you need I can call t-mobile and have them tell me which version it was on.
I did these steps. the file took a hour to download. and It still didn't work. I follow all steps down to the exact. and when I pressed start. within one second it said FAIL. just the other attempts I made.

Unless your t889 Note II was sitting in a drawer and not being updated for the last year or so you probably have 4.3
When you go to download mode do you see "custom binary download: yes ..."
and do you see "knox warranty void:" ?
if so, your phone has been rooted.
but unlike your case, when I try to install stock rom through Odin, it goes through the motions of installing and gives message pass - that is that the stock rom has been installed, but unfortunately it has not installed any rom that my phone can read.

Since your phone is not rooted then I think that ciphercodes advice will not work as you can only install a stock rom that way only if your phone is first rooted.
Probably you should try to root your phone using instructions from this thread
http://forum.xda-developers.com/showthread.php?t=2562994
But this might not work for you as it could be that efs file is corrupted or something else as we both boot up to a black screen that only has Samsung logo

Since your phone is not rooted you may be able to get it repaired under warranty. I think that Samsung warranty is only good for a year, but if you purchased your phone with a American Express gold card (I think other gold cards will also apply) your warranty is extended to double what the original was. So perhaps you have a chance to have your credit card pay for the repair.
Otherwise:
I am no expert but if you want to continue playing with your phone before you get expert advice you may want to play with the recovery mode. To enter recovery mode press volume up and home and power buttons at the same time. once you feel vibrate or after a while release the power button but continue to hold volume up and home buttons and then you will enter recovery mode. you may want to go to menu that says wipe data/factory reset and see if that works. It may be that it is like my phone and the system cannot be mounted in which case you will get that message. After you are through to get out of this menu remove the battery.
But please be aware that I am no expert and you are using this info at your own risk
but I think of doing something catastrophic using this advice in my non expert opinion is small.

Yeah the warranty is expired. and I have tried recovery mode. thats actually the first step before trying to apply a firmware. So recovery hasnt worked either. Guess I will just have to get a new phone. thank you all for oyu help tho. I apperciate it

I was just reading through the thread.. It doesnt seem like you tried flashing Tmobiles Stock 4.3 Firmware in download mode. If you tried to flash a 4.1.2 Firmware when the phone was already updated then I think thats where it failed. Try again but with the 4.3 Firmware through ODIN. After it finishes try rebooting it manually and/or if it doesnt boot again then go back into recovery and factory/data reset again...shouldnt hurt to try..

Bootloop - No Custom OS - No USB Debugging

Hello All,
I am using Samsung Note 3 Neo, unfortunately I have struck up with bootloop. I have read around and tried all the bootloop fixes but they all require the phone to have USB Debugging enabled prior for the fixes to work. Sadly for me, I didn't have the prior knowledge that that was available so I am stuck with a soft bricked phone with no work around.
Any help on issue is greatly appreciated.
Thanks in Advance

You can still access download mode (volume down+home+lock), right? Try flashing TWRP using odin ( i don't think you need to have usb debugging enabled) and then wipe everything and flash stock rom. Or if instaling TWRP does not work, flash directly stock rom using Odin. Hope that helps

I am not able to access download mode, I tried using volume down+home+lock button, Its not getting into Custom OS mode. Just black screen blinks and same samsung logo will come for thrice it will blink and then goes into bootloop

Hmm.. Can you access your stock recovery (home+lock+vol. up)? If you can, try doing factory reset and reboot. Not being able to enter download mode is really rare

Is your phone a Note 3 or a Note 3 Neo? These phones are two different variants.
Can you access download mode? (Phone off, press volume minus + home key + power at the same time until you see the phone starting to ask you if you want to procceed to access to download mode)
If yes, your model number is written at the top, download the latest firmware available for your phone model on samfirmware and flash it using odin, follow a tutorial if you are unsure cause you don't wana mess your phone up more that it already is.
If it cannot access download mode, this is gonna be a bit more complicated :/

Note 3 Stuck on Tmobile Splash Screen - How to recover without losing data?

I have a galaxy note 3 which is stuck on the Tmobile splash screen.
I am not sure if this phone is rooted or not.
I don't want to wipe the phone because there is contacts and things which need to be recovered.
We can get into recovery mode, but not into Safe mode.
Can someone provide some tips?

If your contacts are synced with a Google account, they should appear if you sign in on another phone.
Flashing a ROM to a phone will carry risks; therefore, no matter what you do, you may wind up losing all of the data. That being said, you could try reflashing the stock ROM with Odin and it may boot without wiping.
You could also flash TWRP to the phone, boot into TWRP, mount the data partition, connect it to a computer, and copy off the data. Alternatively, you could try and copy information from the phone to a micro SD card in TWRP.

Did you fix your issue? I had this problem when....

I hope you have fixed your issue by now however if not then please try this.
1. Remove your battery from the phone
2. Hold your phone (volume down button + home button) then slide the battery in and power the phone. *Note you must hold the (volume down button + home button) until you get the warning about installing custom OS.
+Once you reach Warning OS page, at this point Oden should see your phone so you can download a custom recovery like CWM / TWRP
3. Download (Oden + Device Drivers & TWRP) --- I just found out that I need to post 10 times before I can link to outside files so I hope you get the links. If not then PM me and I will try to send directly to you.
HTML:
https://download.chainfire.eu/354/CF-Root/CF-Auto-Root/CF-Auto-Root-hltetmo-hltetmo-smn900t.zip
CF-Auto-Root which includes your phones correct Oden version
https://dl.twrp.me/hlte/twrp-2.8.7.0-hlte-4.4.img.tar"]TWRP.
4. Extract the CF-Root folder you downloaded using 7zip and you will see Oden. Install Oden on your PC.
5. Connect your phone to your computer and look for a so your connected to Oden and then flash TWRP .tar file to your phone. Once it flashes then your phone should reboot automatically and you should have access to your old data.
This happen to my Note 3 T-Mobile phone when I was trying to flash the wrong versions. If you are confused about the directions then I will do my best to make a video for you. It might take me a day or two to respond with the video. Hope this helps! Let me know how it works out or if you have any questions.
Also, once you gain access to your phone again I recommend taking a look at some of the ROM's on this website! There are some developers who have put quality time into making their ROM's SOLID working systems.
Always remember to give support as this is what makes this community attract real talent!

I do not recommend CWM as it is very outdated.
Rooting is not required to flash TWRP, only Odin and the tar version of TWRP.
The phone can be rooted by flashing supersu from TWRP too.

Tab S 8.4 Stuck in recovery loop

Hi Folks,
I have a Tab S 8.4 wifi that I seem to have broken. I was attempting to restore the stock Marshmallow rom and something has gone horribly wrong. This is what I did:
1. I installed the latest stock rom by Odin and booted
2. I then downloaded and installed CF auto root/TWRP for the SM-T700, however, I failed notice that I had left NAND erase checked in the Odin settings so now all I get is the device attempting boot into TWRP which doesn’t work.
The device won’t turn off to allow me to use the buttons to access download mode which I know is what I need. I have tried draining the battery completely but as soon as power is restored it attempts to boot into the failed recovery again and is, in effect, stuck on the TWRP screen, periodically flashing the screen. It its broken TWRP state, the computer recognises it as a USB MTP device but will not recognise with the correct drivers to allow me to use ADB to force it into the download.
Does anybody have any suggestions? Otherwise I have a £250 paperweight!

I have tried draining the battery completely but as soon as power is restored it attempts to boot into the failed recovery again and is, in effect, stuck on the TWRP screen, periodically flashing the screen. It its broken TWRP state, the computer recognises it as a USB MTP device but will not recognise with the correct drivers to allow me to use ADB to force it into the download.
Does anybody have any suggestions? Otherwise I have a £250 paperweight!

The file you flashed doesn't work on Marshmallow.
Use the updated twrp and supersu in the dev section.

Thanks for the reply ashyx, I don't current have a way to achieve that as I cannot access download mode. Any suggestions on how to do that?

You can access download mode anytime irrespective of the current state the device is in.
Hold POWER + HOME + VOL DOWN until the device boots in to download mode.

I did't realise it would work in any mode!
Thought I'd tried it but obviously not held long enough.
You are a star! Thank you so much.
