attempted to root and failed, need help please

Hi, I started out with a stock tmobile s3 and tried to root it for the first time today, I followed this video
http://www.youtube.com/watch?v=mndQZqom3Ac
which asked me to use this cf-root 6.4
http://forum.xda-developers.com/showthread.php?t=1695238
when I hit start on that .tar file under odin, it failed stating "complete (write)operation failed)
since then, my device would boot with error "firmware upgrade encountered an issue" nothing else would happen.
I tried to go into recovery mode again and this time when I tried to retry the odin tar install, it would give me a new fail of cannot open com3
When I tried to use kies, it would just forever try to connect and never connect. so I couldnt do anything there.
What can I do? I would preferably try to retain all my saved data.
I also suspect my usb port might be faulty, sometimes need to press it in firmly to make the usb mass storage to work properly.
Thanks in advance

i really didnt note which version i have... noob mistake i kmow. i think it is 4.2...is there any way i can check?

Ok, I totally messed up when I first attempted this. The .tar I used was for an international s3 and I have a tmobile us version!. the OP of the thread says it may even brick my phone if I attempt this on a non international version.
competely my fault, but what should I do to fix this and save my phone?
I cannot connect to kies, reinstalled the drivers and it still wont connect. just gets stuck in "connecting"
The odin now doesnt load a tar because it says "cannot open com3 "
EDIT:
fixed it, odin was not working due to kies running in the background and I finally was able to flash the correct chainfire for my phone

Glad its sorted out. I assume no issues now ?

Bricked Note 8 AT&T SGH-I467

I've searched, I've tried but to no avail have I been able to fix my poor note 8..and I'm hoping someone can help!
I HAD a stock 4.4.2 Note 8 (AT&T version I-467) running, and I went with the Kingroot method to root. The device rooted but ran like a dog, and in my infinite wisdom did a wipe/reset to see if that would help.
Now here is where I stand:
1) The device boots to a screen saying unauthorized firmware
2) I can get to download mode (power+vol. down+Home)
3) I can NOT get to the screen with (power+col. up+Home)
I have tried Kies, and it won't take the serial number/model number, and Odin can only seem to flash the boot loaders. I have tried 4 different ROM's from samsung (with different international codes), and none of them are able to update the system (they all fail at about 90%). I've tried the all in one toolkit, and since I can't enable USB debugging at this point, it never recognizes the device as attached.
I've tried manually flashing with Odin TWRP, Phils, and stock recovery,(in the hopes of getting one to take so I could load a new ROM from SD card) and they all fail as well.
When I split any of the system images I can load a boot loader file from them, and it succeeds, but everything else fails.
Can anyone point me in the right direction, or am I completely hosed?

+1 on that, I'm stuck in an exact same situation. No help from Samsung either. After rooting with Kingroot my tab started acting like crazy with flickering screen and random reboots, did exactly like you did.
There are many with similar issue and as per my research most of them have given up. Getting a system image dump from a rooted tab running 4.4.2 might be the only way out. Unless of course Samsung/AT&T decides to release full odin flashable image.

I was in a similar situation from trying to fix a eff problem and took my sgh-i467 to a Samsung Experience Center located in many Best Buys and they fixed it free of charge. They were not able to fix my issue with a corrupted EFF file that is keeping my 4G from working though as I had hoped. If you have a Best Buy around with the Samsung Kiosk in it I would give it a try. I ended up trying a few different ones to fix the eff issue and some of the employees at the Samsung centers were about as smart as a head of cabbage (they laughed at me when I said my Note 8 was the issue and said "you can't have a Note 8 the Note 5 just came out") but some were at least helpful and listened when I told them they have the tools to fix my tab (reflash it back to life) and they did. Hopefully they can help you.

man Im in the same exact situation.. And I cant seem to find any help anywhere. I cant locate a stock 4.4.2 kit kat odin flashable file anywhere for the n5120

please help me i need de 4 files repair from this tablet

Try the forum thread started by djjiz, https://forum.xda-developers.com/galaxy-note-8-0/help/i467-4-4-2-t3537302... He posted the files and yes I was able to bring back my previously bricked AT&T Note 8.

I messed up pretty bad

So, as we all must know by now, the Note 4 Retail version got the CID conversion, and now we have access to root.
But I have no such thing, because when I was messing with TWRP I couldn't flash SuperSu or Emotion r21. This resulted in a bootloop, and since I couldn't find a working way to get out of the bootloop, I decided to wipe the phone. The only issue is that I somehow accidently uninstalled android itself, leaving my phone without a system.
And now, I have used some files from http://forum.xda-developers.com/not...mware-firmware-kernel-modem-recovery-t2942937
To be more specific, I tried to flash the "Stock restore" file, as that seemed to be the best option. I got about 98% of the way through it with Odin before I got a write-denied error.
And that's strange because I have my phone in developer mode.
And now, if I plug my phone in, it gives me a screen telling me that I must use the Verizon repair assistant application on my computer, although it doesn't recognize my phone unless its normally booted up.
Hitting the power button brings me to a download mode like screen, with the text in the top left, but a picture in the middle that tells me to use Verizons repair assistant.
The screen says "Software Update Failed ... Your device didn't update successfully. Use the Verizon Software Repair Assistant on a computer to repair your device and complete the update."
Booting into recovery mode doesn't work
Booting into download mode does work, however it doesn't allow me to flash anything through Odin.
I have a Verizon Note 4 N910V Retail (w/ CID change), on 5.1.1 and latest bootloader
EDIT: Also, Odin doesn't recognize when the phone is plugged in, but the pc does. The pc doesn't know what it is though.
Odin has recognized my phone after I left it off over night
Does anybody have any idea on how to fix this? There has to be a way, since its not a bricked phone
Any help is greatly appreciated

Did you try to use verizon repair assistant?

Yes,but it refuses to recognize that my phone is plugged in

UPDATE: I flashed TWRP and i forgot to uncheck auto-boot, but it did get me out of Verizons restrictive boot. Also, Android is now present , just needing repairs
EDIT: Android is starting! Hopefully is someone else does this incredibly stupid and reckless use of TWRP like I did, they'll know how to fix it (to an extent). Sorry if this thread was more of a waste of space since I just fixed it myself (miraculously).

S6 Edge+ (G928) t-mobile soft bricked after OTA upgrade to 6.0.1 while overseas HELP!

Hello, I managed to soft brick my phone while overseas and am writing this message at 2:00am in the morning (at least in this time zone) after two days of trying to fix it. Some background info--I'm usually based in the U.S., have a Samsung Galaxy S6 edge+ with service from T-mobile. Have never rooted or modified the phone in any way. I'm using a macbook pro laptop (running a windows virtual machine/vmware, on the mac) on this trip.
While on this current trip to Asia (currently in the Philippines) (much to my surprise it seems like the phone was getting 4G data here), I accidentally bumped the "yes" button on t-mobile's persistent OTA upgrade request box and the phone started a OTA upgrade, I assume to Android 6.0.1. I kept an eye on the phone as it went through various stages of progress in the upgrade. didn't see any error messages. It eventually restarted, got to the T-mobile screen, and got stuck there. That was two days ago. I've done quite a bit since that time to try to figure out what went wrong, searched all over online to find potential solutions. it goes without saying if there is any way possible i need to recover many important files on the device, so a reset is the option of last resort.
Long story short, seems like the farthest I can get on the phone is to Android Recovery mode, or the download screen. I installed the android tools and have "adb" working from the mac command line. Bad news is, it looks like I didn't have USB debugging mode activated on the phone, now I can't see any possible way to activate usb debug mode because the phone just won't boot past the t-mobile screen. I can get adb to detect the phone for a moment if I select "apply update from adb" on the recovery mode screen but that's about it, haven't been able to issue any other commands to the phone through adb other than detect and sideload.
tried to reload the android image...via command line adb sideload G928TUVU2DPD1 but get error messages about failure to verify (i think), anyways adb sideload wasn't happening. I installed Odin on my windows VM, attached the usb bridge from the mac to the windows vm and Odin was able to see the device. I was able to successfully push G928TUVU2DPD1 to the phone's download mode, both Odin and phone seemed happy about the file transfer, the phone went through a install process, restarted, with the exact same result as when the OTA update finished - phone stuck at the t-mobile screen after reboot.
I tried to load TWRP to the phone with hopes to run backups, and was actually able to transfer TWRP to the phone using Odin, yet TWRP wouldn't install -- the phone complained of the unauthorized binary. i guess the phone has to be rooted first or something else needs to be flashed to defeat the binary check, haven't tried that yet.
So I'm stuck with a soft bricked phone for now, yet instinct tells me with Odin working and talking to the phone, I should be able to install -something- that will get me back in business...that's why I'm posting this message, to ask for help as it seems like this group is the go to place for this type of specific info.
i am not at all familiar with custom android work yet have been active with tech stuff for the greater part of my life, plenty of coding and experience dating back years and have done dev work in most of the popular languages, very comfortable with command lines, log files and so forth...just never had a reason to mess around at a low level with my android phone until the past 48 hours, so i'm not really familiar. does anyone have any ideas? as a next step i'm thinking of trying to push a downgrade to the phone through Odin which I suppose would be Android 5.1.1 , although I haven't yet located binaries that feel exactly right for t-mobile and s6 edge+ ... sigh, this has been quite a time consuming way of learning the bricked phone recovery process..
:good:
thanks in advance for any ideas or help on this...it's quite disturbing to be on a business trip with no phone, and the past 6+ months worth of not backed up (gulp) data still sitting on the device (hopefully)..
here's some data from the Android Recovery screen:
6.0.1/MMB29K.G928TUVU2DPD1
samsung/zenltetmo/zenltetmo
was flipping through the recovery logs and i notice quite a few log entries about "couldn't find any tzdata when looking for localtime!" , I notice entries like "Starting recovery on Fri Jan 2 03:55:29 2015" -- i'm wondering if the phone is having trouble setting internal time and date which might be preventing it from booting...just a theory.
sorry for the long message, wanted to completely describe this fun scenario, just in case anyone has any ideas..thanks again

keep trying to load TWRP from the download screen on my phone...but get the "custom binary blocked by FTP lock" message. There's no way to change any settings on the phone as it still won't boot past the t-mobile screen..

Can you download Odin?
Sent from my SM-N910T using Tapatalk

yes i have installed Odin and it's working fine...I can push files to the phone in download mode and it works fine, but the Android images i have loaded so far all seem to result in the phone getting stuck at the t-mobile screen...it won't go past there

Did you ever get this figured out? My guess is it has something to do with not being connected to t-mobile home network. The fact you can get to download mode & Odin sees your phone should mean all hope is not lost yet on recovering your files and getting it working again.
Twrp isn't going to work unless you had root installed with the USB debugging & oem unlock option turned on in developer mode.
Maybe try asking in some of the other s6 forums. There's a lot of knowledgeable people here & I'm sure someone knows how to fix this.
Goodluck, I hope you get it figured out, I know how frustrating it can be.

[Samsung] Galaxy Tab 3 SM-T210 / "Firmware upgrade encountered an issue"

Hello!
Few days ago i found my Samsung Tab 3, and decided to charge it and biit it up.
It got stuck on Samsung logo when i booted it.
So i did a factory reset using the recovery mode.
After i did that the device booted up. with lots of errors.
I was on the setup screen for my device and these errors appeard and said like core has stopped working and every like preinstalled app on my samsung device aswell (NAME has stopped working). So i was not able to fullfill the setup of my device.
I read about it online and a firmware upgrade could fix the problem ( Like the easiest way i read )
So i did some googling and downloaded Odin and a firmware. Followed a guide and did everything right. BUT the process faild like 8min into the flash.
And now my device is stuck on "download mode" but with the error "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
I cant get the phone to turn off, nor get into recovery mode or anything else. I tried flash again but no luck.
I also tried another firmware i found. still same problem.
How do i fix this and how can i use my samsung tab 3 again.
WHen i bought it years ago i never really used it. So it's in "new shape" and has never really been used. And now i wanna give it to my little sister for some kids games to play at Xmas.
I hope we can solve this problem.
Thanks in advance
Regards
Timmie

That depends on various things, such as the Android version, kernel and change ID. Than also the Odin version you've used and/or the settings during the attempt of flashing. I found that using the wrong Odin version on a particular Android version, that may prevent the flash of being successfull. B.t.w, did you format both user and cache partition while trying to reset to factory default?

Yeah, I've found out what Odin version to use that worked for others. I've downloaded lots of different firmwares and such and tried. ALL fails.
When i did a factory reset i also cleared cash and user.
Now i cant even turn off the damn thing. If i charge it up and start, it just goes directly to the screen where it says "Firmware upgrade encountered an issue" and if i try to turn it off, it just reboots and goes back. And i cant even return to factory reset page.
I think that my Micro-USB cable might not work for this, or is that a thing? Do i need a good cable from PC to Phone for this? Or does any cable work?
I just want this tab to work. been trying for weeks.
Thanks for your reply. I hope we can sort this out.

It is quite easy to turn the device off, for that to happen you have to press and hold the on/off button. You'll see that the device will shutdown and try to reboot and then finally shuts down again and stay off, then release the on/off button.
Are you sure trying to flash the correct firmware with correct changes, etc??
Please share with us the device and Android version, as well as the stock ROM version with changes you're trying to flash.
Put (copy and paste) the output of Odin below.
Another way to get the firmware flashed is by using Heimdall, but for that to happen you first need to rename the extension of the stock ROM (remove .md5 and leave .tar) and than extract all seperate pieces that are contained within the stock ROM.
All those extracted pieces from the stock ROM you have to upload seperately onto Heimdall and try to flash them to your tablet, one by one.
Heimdall you'll find 'here' or use FWUL instead which has Heimdall pre installed, download is to be found 'here' and install it on a USB medium a stick, to put FWUL onto USB, use Balena-Etcher and the download is to be found 'here'.
Micro USB cable does work, but if you're unsure, try another one and make sure using the correct drivers too.
Using Odin, make sure the tablet is recognised and 'connected' in Odin, also make sure 'repartitioning' is unchecked.
If you've used the wrong Odin version, flashing will fail!

Hi, complete novice here, does anyone know where I can get a working Firmware for my Tab 3 v7 (SM-210)?
I have searched through various forum articles here, and tried to install with several builds but none will install. The only one that gets anywhere near is the JASBR build by gr8nole. It appears to install, but on restart, the TAB just sits on the "Samsung Tab3" start screen.
I read that I may need to flash the firmware 4.4.4 (Kit Kat), but can't find it!
The unit is not totally bricked (yet), as I can run TWRP 2.8, with which I created a backup of the original build, but when I try to restore the backup, it fails at just over 31%.
Can anyone help please?
