Need Help, Bricked SM-T900

I bricked my SM-T900 Wifi while attempting to root it. Can anyone help me get it un-bricked?
Here's a step by step list of what I did and what happened:
1. Turned on USB debugging mode
2. Downloaded and installed Samsung kies
3. Downloaded the file for SM-T900 from autoroot [dot] chainfire [dot] eu/ (it won't let me post outside links)
4. Turn off tablet, get into custom firmware installation mode by holding power, volume-, and home, then confirm the warning
5. run Odin (v3.07, came in the zip file)
6. plug in tablet, tablet showed up as a com port but did NOT show any other information. I don't know if it was supposed to show anything else but I hadn't though about that at the time.
7. Clicked on PDA and selected the file CF-Auto-Root-v2wifi-v2wifixx-smt900.tar.md5
8. Clicked start
9. Waited, it said it was doing something with cache, I don't recall exactly what it said
10. after about 3 minutes the screen looked wrong, all the pixels were different colors, (rainbow static?)
11. Waited about 10 minutes just in case that was not a sign of failure, then Odin reported that it failed.
Now when I press the power button, I get the screen that says "Firmware upgrade encountered and issue. Please select recovery mode in Kies and try again"
I tried using that in Kies but Kies can't connect to my tablet any more. When I try to use Odin using the recovery with power, vol-, home, it detects that I plugged it in but when I try to click start it fails and nothing happens.

I have exact the same problem.
I have read many articles, who said it was easy to root.
That's not true !!!!.
Maybe because the tablet became an update today ?
What I did to recover the tablet: (phew !!!)
Download this bootloader:
http://forum.xda-developers.com/attachment.php?attachmentid=2591013&d=1392923580
Connect to Odin and flash it.
A few seconds, it says OK, reboots and voila: there's your tablet again revived !!!!.

Unfortunately Odin fails before it manages to even connect to my tablet so I'm not sure it will work for me but I'll give it a try. It managed to connect before when I tried to flash the root files but now it fails every time. I'll update this when I get home and try flashing that.
Edit:
Got home, tried your fix. I am happy to report it worked and it only took a few seconds. Thanks!
Edit:
To anyone reading this thread, if you tried rooting your SM-T900 using the SM-T900 files for rooting, try using the SM-P900 files instead! I just tried that and it seems to be working fine.

I'm glad I could help. :good:
It's bad for your heart when you see that your expensive tablet is bricked.

Hello everyone. Where do I flash the bootloader in odin? Do I use PDA or Bootloader and do I need to check the bootloader update box? Just wanted to confirm before further messing up my tablet. Thanks!
Edit: Never mind, figured it out. Thanks for the help!

This method just worked for me. Flashed the bootloader with Odin after getting "stuck" and it booted right up.

What did you do exactly to fix it? I'm having the same issue. Just sits at screen and says:
ODIN MODE
Product Name: SM-T900
Current Binary: Custom
System Status: Official
KNOX Warranty Void: 1
RP SWREV: A1
How do you use that recovery.img file?

For the top most problem flash cwm or TWRP recovery through Odin or through recovery mode then boot into cwm or TWRP recovery delete all files and install a supported rom.
If u want full explained steps mail me
- [email protected]
Sent from my SM-J500F using XDA Forums

it's 2022 & my T900 finally went into bootloop in model logo, does anyone know the real reason for this? is it hardware or software problem?
- I can flash any version via odin but still bootloops
- TWRP worked once after that can't get in anymore
- the only button working is for the download mode PWR + Vol Down
- before all this LED Stayed on until batt drained then bootloops
it's a good tab to watch movie while on a treadmill

Stuck on the Samsung boot animation after disabling SuperUser on rooted N920C

I have been trying to fix the random reboots that came with the SpaceX kernal for Note 5 N920C and now I cannot boot my phone.
I have tried wiping all data and clearing cache. I cannot find a stock kernel.

Your phone should now tell you that you have no operating system. And that should be why you're stuck in a bootloop. In this case you will need to install the original firmware back on your phone and start the rooting process over again. The easiest way to reinstall the original operating system is to use Samsung Smart Switch on PC.

I'm not sure where my phone is from and I need to know that on Sammobile to get the right firmware. On my warranty card under Country it says Pays, [Some Arabic writing].

If you use Samsung Smart Switch, it will ask you for the model of your phone, and the Serial number. Then it will find the right firmware for you. The way you would get to that information on your phone is to boot in download mode.
"While the phone is off, press and hold the volume down button, power button, and home button at the same time. As soon as the phone starts to boot, let go of the power button while STILL holding the volume down, and home button."
Your phone should boot into a minty greenish screen. Press the volume down button again and it should give you the SN for the phone. That should help in locating the correct firmware for your phone.

Flash my SkyHigh kernel and should boot. Will auto root again.
Link ? Search. ..

If you mean the SM number, I have that along with an IMEI and other information that came with the phone. Right now my problems seem to be:
Cannot flash any custom ROMs because I get stuck on "NAND write start!!" on ODIN. I have tried multiple ROMs, multiple USB ports and multiple versions of ODIN.
My computer drivers for my phone seem to fail after about a minute of using my phone causing my phone to be seen as an unrecognized device. I have tried re-installing the drivers many times.
When I go into smart switch it never recognizes my phone. When I plug it in on the Download Screen it just says "Connecting..." and eventually says my device is unsupported.

Okay, here is an update.
I tried initializing my phone after smart switch failed to connect to my device and after putting in a serial and model name it says that the N920C does not support initializing.

hi,
As far as i know Smart Switch does not support./work on rooted devices..?
I might be wrong, but this is what i have read in other similar threads/post in past.
Plse check, this fact to be sure, otherwise you wasting time trying to get it to work.
Good luck
post note.
Stock kernel is included in stock Rom.
If you try to flash old stock Rom it apparently won't work(re bootloader updated etc) . It has to be the correct latest stock Rom for your particular device! not just any Rom..?
I also noted it has to be Odin v 3. 10.7 ? something /i believe.
plse note
i can't really say for sure as,
My Note5 is not rooted...... yet all my other devices ..... Note 2.. 3....4 is !
O, yes i also have N920 C device (not rooted) and Smart Switch works fine.

It kind of sounds like zit is a driver problem. You said you did a full wipe of data and operating system on phone. So I wonder if it could also be the type of firmware you are trying to install? I would try to install a fresh copy of the new stuff firmware from Sam mobile or smart switch in order to make sure all the drivers are pm running properly. @wilcor I agree with you 100%. I am a little confused as to why the phone would fail when installing roms or fresh firmware??

Ok, thanks everybody I eventually got this problem sorted. I called samsung and they told me what country my device was from and after that I made sure I used ODIN 3.10.7 and the ROM for AFGHANISTAN and it installed successfully. Thank you for all your help.

GT-I9295 Brick? Stock ROM fail on system.img.ext4 in Odin

Hi all.
A newbie, I ended up lost after trying to flash the latest CM 12.1 on my Samsung Galaxy S4 Active GT-I9295.
At first, there was an issue with the recovery, which upon entering showed black screen instead of the tool itself.
Trying to fix this, I managed to remove the recovery through flashing the Stock ROM, which has failed in Odin on the "system.img.ext4" instead - could not paste screenshot link here, feel free to ask for it, please!
I must say that I have tried hard to figure out what to do with the mess I have caused, but now I am helpless.
Would anyone give me some nice piece of advice to get my phone going again?
Thank you so much!

Did you try odin 3.10 by any chance? That could be the problem. Use odin 3.07 or 3.09, boot manually into download mode with complete shutdown & using vol down + power key and odin the stock ROM, reboot and do the same with TWRP (hold down the vol up key after flashing recovery when it is rebooting)

Hi there, Jason.
Yes, I did exactly as you say - got to the download mode, plugged in, ran Odin (tried 3.10, 3.09 and 3 v1.85) started flashing the latest Stock ROM and the I only got as far as the "system.img.ext4", when the download failed. Sometimes that happened even earlier, saying that there was no PIT etc.
When trying to flash the CWM recovery, it goes through OK, but then when trying to get into it, the screen just goes black, as described in my previous thread - "CWM or TWRP Recovery Black Screen".
I am stuck.
But I still hope that I am not a proud brick owner

Are you using the original USB cable if not then try with another cable. Also what is the device name shown when you boot into download mode

Hi. Try this:
Remove the battery and USB cable from your phone, and wait at least 3 seconds.
Place the battery only back in your phone.
Fingers on volume down and home, then another on power. (cold boot directly into download mode - this is important!)
Press up to enter download mode.
Insert USB cable into phone and lie it down somewhere it won't move or be touched during the flash.
Download a good current copy of Odin from:
https://idlekernel.com/flash-tools/Odin_3.10.7.zip
Extract the archive and run Odin.exe
Download this emergency recover tar for your device (newest firmware revision available as of right now):
https://idlekernel.com/flash-tools/recover/BL_I9295XXUDPA4_RECOVER.tar.md5 (also has official TWRP 3.0.0-2)
Insert "BL_I9295XXUDPA4_RECOVER.tar.md5" in the [BL] slot.
In the Options tab put an [✔] in the "Phone Bootloader Update" checkbox.
If you don't have anything you need on your internal storage, put an [✔] in the "Nand Erase All" checkbox.
Click [Start].
Once the progress bar is near finished, place your fingers on volume up and home to enter directly into official TWRP 3.0.0-2.
If you used the "Nand Erase All" feature earlier, you will need to go into Wipe -> [Format Data] -> type "yes" for your data partition to be usable again.
Hopefully this will get you past your black screen issues.
PS. Remember to flash stock boot.img with your system.img.ext4, as you cannot boot a ROM without a matching boot image.

What is your exact model number so i can give you correct files links ?
For example T-mobile note 4 has 3 models (SM-N910T / SM-N910T2 / SM-N910T3 .which 1 of these 3 you got?
You can simply check your model number by pressing 3 button combo while device is switched off (volume down+home+power) will boot into odin download mode press volume up to continue there you can see your device model number on top left corner.
It will be better if you can take a photo of your device while in odin download mode and and upload it so i can see what else will require to fix.
Let me know and I'll get back to you.

What kind of error pops up ?
Do factory reset 1 more time.after reset let phone completly cool down dont touch anything .
then you complete setup.
Use high speed microsd card if microsd card is not good it can cause issues and lag to whole device.
Download wake lock app from playstore and open the app you have to click on partial wake lock as shown in screenshot below.it will manage your cpu to run more efficient.
If issue still remains you have to erase old nandroid completly by using PIT FILE and repartion your internal memory to flash fresh nandroid.
Try first the things that i mention and use your device for 2 days.if it didnt work after that you can try erasing nandroid with my guide.

I think I'd rather go with that option as I just tried what you mention in earlier message and still gets the same error. Can you help me out with erasing old corrupted nandroid. Let's give this one a try cuz till now I tried almost every thing and yeah I just noticed another thing which is my phone's ICCID is also Unknown. I am not sure but do you think this might be causing problem?
Thank You Once again for so much help.

Hi I'm unable to connect my phone to pc unfortunately and Now I believe this is hardware problem as when I decided to get my phone unlocked the person who was unlocking couldn't connect either so he'd suggested me that it's a hardware problem and couple of days later I was able to connect to PC till today. so I think I won't be able to perform repartition my phone until and unless I get my connectivity back. Thank You so much for your help anyway. I'd definitely give it a try as soon as I get my connectivity back and will update you.
Thanks

I just tired, and nothing worked out. the place where I took my phone to unlock he actually changed the charging and connecting port to check if it's port problem but the result was same until it gets back connectivity on it's own. I just changed the cable reset phone couple of times. It's not even connecting as a media device.

Note 9 bootloop out of nowhere!!

So let me give you a little background first. I was at my brother's house recording him dunk in superslowmo. All of a sudden, my phone freezes. After about 2-5 mins I decide To hold power +volume down and the phone goes black and goes to the "Samsung Galaxy note 9 secured by knox" screen and does a infinite reboot to that screen. The phone will not go into recovery mode BUT will go into Download Mode. I tried letting the phone completely drain and then trying it with no success.
I do have AT&T protection on my device but the only thing they will do is replace it which I'm trying to avoid being that I have pictures I want to extract from the phone.
So to my question(s)
1) if I flash latest version of firmware from sammombile will I lose my pictures? (Trying to avoid loss of pics)
2) can I use a MacBook to do the reflashing or does it have to be windows?
Please and thx to all that respond!!!

Once in download mode hold volume down and power to see if phone boots up. If you reflash with Odin use home_csc so it does not wipe your data. If you do get to recovery do not do a wipe, everything you have saved to phone storage will be gone. See if you can get to device storage by connecting to computer once your in download mode or recovery. If so just move all important files to computer then you can use Odin to flash firmware.

1) while flashing in Odin, the CSC file determines if your phones data is erased or not during the flash. In order to retain personal data, flash HOME_CSC..
2) you can use Jodin to flash on a Mac https://forum.xda-developers.com/devdb/project/dl/?id=20803

Okay I ditched the macbook idea and I have my aunt's computer in from of me.
When installing the firmware.. Am I going for the latest USA version which is from like last week... Or do I do the ATT firmware from Nov 2018 and do the OTA update?

We're you already on the latest firmware? If you are then just flash the latest and use home_csc

I'm going to try that now. Just look at what version of Windows I have and it's 8.1... does that make a difference of why the drivers won't install ?
This is the error message when I try "mss installwizard for samsung usb driver for mobile phones failed "

When I was installing smart switch it told me to "disconnect my device from pc"( which it read AS A Samsung phone)
But when it's all downloaded It just says connect device again but when I do the computer makes its sound and then nothing.
If I'm in device manager and I plug in my note 9 it pops up as 'sdm845' but says there are no drivers installed.
I uninstalled the Samsung drivers (even though it says failed) and I tried again and it said fail to install again

Okay if anyone Is still reading this.. If I switch up and use my Father's Macbook instead, does anyone know the necessary steps to continue on with the process? And keep in mind the state of my phone is in a boot loop and only goes to the download screen

I was just doing the whole chatting thing with a Samsung representative and they advise me to go to a place near me to do the reflashing.
but still the thing that's bothering me is that my PC isn't installing the drivers regardless.
without even thinking about my phone connected , I should be able to go on Samsung's website and download the drivers right off the website but when I do I get the "mss installwizard for samsung usb driver for mobile phones failed "

Install this drivers, reboot pc, open odin as administrator, connect phone in download mode.

Did you ever get to the bottom of this ? I seem to have a similar issue, where phone is in a continuous boot loop. It stays on powered by android screen for few secs and then restarts.
I cannot enter recovery mode, but can get into download mode. Have flashed via ODIN few times successfully, but same condition prevails.
Safe to assume MoBo is fried ?

Could be that the main storage in the motherboard is corrupted, which needs to be reformatted entirely.

Just a heads up, Google photos has free backups up to 15gb in full quality, or unlimited backup of 1080 for pics and videos. So at least from now-> forward a hardware issue won't ever cause you to lose pics again. You just need to open the app and setup backups.
