Bricked Samsung Galaxy S3 With Bad Software

I accidentally bricked my Samsung Galaxy S3 with a bad software. Now, It won't turn on at all. I tried this so far by pressing volume + home+ power with no luck. Whatever that I do, I cannot get it to go into download mode. This is what I did that bricked my phone. I really feel so dumb for not seeing the "for windows os!" Any help will be greatly appreciated. Thanks in advanced.
Section 1: (For Windows OS)How to Odin stock pre rooted 4.1.1 JellyBean/Unlock bootloader/Flash a Custom recovery
Step 2: Power device off, hold the volume down/home/power keys until you see a yellow triangle, then press the volume up key to access "odin or download mode".
Step 3: Open odin and connect the oem usb cable to pc & device. There should be a "comport number" in upper left hand corner of odin indicating communication between the device & pc.
Step 4: Click on the PDA function of odin. Select the stock rom you downloaded in step 1, then select start. This operation should take less than 8 minutes before odin will say pass/reset and should reboot. If not manually reboot...
Step 5: Open up the SuperUser application from your app drawer and make sure its up to date!
Step 6: Download the EZ-Unlock app to your device from HERE.(Only use version 1.1 or 1.2 for now as the latest versions have issues!)
Step 7: Open the app and select unlock! Now your unlocked...yup its that easy!
Step 8: Download the EZ-recovery app to your device from HERE.
Step 9: Open app, select CWM recovery, tap the pulldown menu, choose CWM 6.0.1, select flash, then reboot recovery.
Step 10: Congrats you are now rooted, unlocked, and have a custom recovery installed!! If you want to flash a custom rom proceed to section 3 or 4.
It wasn't bad software, just the wrong software. Looking at those directions that is the root and recovery method for a Verizon GS3. Try to get it into download mode again (vol -, home, pwr) and see if you can flash the stock odin files.

Installation:
1. Connect your Grand to your computer via USB Cable.
2. Extract & Start ODIN on your computer, make sure that Auto Reboot & F.Reset is Checked while Re-partition is Unchecked.
3. Restart Galaxy Grand in “Download Mode”. You can do it by switching off the device and then holding Volume Down+Power+Home button simultaneously for few seconds.
4. ODIN should recognize your device [ID:COM will turn blue or yellow], if it does not either your antivirus or firewall settings is creating problem or Samsung USB driver (Kies) is not correctly installed.
5. Check & Hit PDA on ODIN and select the file 'I9082XXUBMI1_I9082ODDBMI1_I9082DDUBMI1_HOME.tar.md5'you downloaded and extracted on your computer. (extract and select).
6. Press Start
After this,
Your Samsung Galaxy Grand will reboot on its own, and you will have official Android 4.2.2 Jellybean Installed on your device.
Note: If their is any problem during installation, like boot loop or force closures, installing the 4.2.2 version or during the install you need to wipe/factory data reset your Galaxy Grand. You can do this by pressing Home+ Power + Volume Up key. There will be an option to wipe/factory data reset select it and your will be good to go.

Samsung Galaxy Tab S 10.5 (can't get out of retail demo mode)

I purchased a used Samsung Galaxy Tab S 10.5 on ebay. Originally it had Android 4.4.2
When I turned it on the device is in retail demo mode.
I have tried the following
1) passwords found on this forum such as (5444, M729Q16K8546, blue, unlimited, easy, galaxy)
2) none of these worked
3) Can not deselect "samsung retail mode" in settings/security/administrators
I tried updating to android 6.0.1 by doing the following but the retail mode is still there
It will not enter into download mode so I did the following
1) Enabled developer options on tablet
2) Used command "adb reboot download"
3) Installed Android 6.0.1 stock rom (T800XXU1CPH7_T800XAR1CPH4_XAR.zip) from sammobile.com
4) Tablet installed and updated Android
5) Retail mode is still there and I still can not get rid of it
Any suggestions are greatly appreciated
Thanks
Never had a retail demo device so my answer may be limited.
Did you tried/are able to install TWRP ?
If you can get TWRP you can try to make a complete factory wipe (Advanced Wipe > check all the boxes > wipe)
Then reboot to download mode (Reboot > Download)
Install the stock rom again
Here is the link: https://forum.xda-developers.com/ga...p-2-8-6-1-unofficial-sm-t800-805-807-t3074633
Flash it via odin
I have tried to do TWRP but can not get it to work. I did not use the apk I was using ODIN on my pc. I was using a TWRP file twrp_3.0.0-0_T800. Not sure if that was the issue or not.
Here are the steps I used:
1) put phone into download mode by using adb on pc (adb reboot download)
2) In ODIN
a) turn off autop reboot
b) select AP file twrp_3.0.0-0_T800
c) wait for success in ODIN
3) tablet never rebooted so I used these keys (press at same time until reboot power+vol down+vol up+home)
4) Tablet rebooted into normal running mode
If you don't enter in recovery right away you flash it the system will revert the changes back. so if the system start to boot normally you need to flash via odin again.
I recommend you to flash the version i linked, as it is more compatible with MM bootloader, also turning off auto reboot is a very important thing.
You need to press all the buttons together power+vol down+vol up+home, (press power last) . when the screen light up release the volume up button (the next to power button) and keep holding the rest.
also...
You can try one trick that i use sometimes, it will give you more time to make the key combination, connect the device to the charger and press and hold power+vol up until the screen turn off, it may show a battery icon, so you disconnect the charger and wait the icon go away. the device should be turned off now. so you basically press and hold vol down+home+power (press power last)
If you done the combination correctly and the screen became black, don't worry, it is a bug, just wait some time (1 min i think) and press home key, it should show the recovery.
It can be a pain in the a** sometimes... but trust me, it generally works.
Ok, so far so good. It took a while but I got into TWRP. But I can't seem to select the image file.
I have it on an external MicroSD in the root. File is called T800XXU1CPH7_T800XAR1CPH4_XAR.zip
I can browse files on the list on the left. But I can't seem to find the file
Did I miss a step?
Somehow after going through menus, it recognized the file
But when I tried to install it, I got these errors
Zip Signature verification failed!
Error installing zip file /sdcard/download/T800XXU1CPH7_T800ZXAR1CPH4_XAR.zip
Could not find 'META-INF/com/google/android/update-binary' in zip file
Error installing zip file /sdcard/download/T800XXU1CPH7_T800ZXAR1CPH4_XAR.zip
you got me wrong, in the TWRP what you need to do is make a complete wipe (Wipe > Advanced Wipe > check all the boxes > wipe)
then you need to enter in download mode. (Reboot > Download)
and flash the rom via odin!
extract the zip on your pc, it should be a .Tar file, select AP mode on odin, select the .tar and flash it in there.
I apologize for the confusion. Those steps worked!!
I think part of the problem is that I did not extract the firmware file. I kept trying to flash the TAR file.
I did a wipe in TWRP
Then rebooted into download mode
Flashed extracted firmware file in ODIN in AP Box
Then the tablet rebooted and was in setup mode like a brand new tablet!! Who hoo.
Works great
Thanks for all the help
