Tab S6 stuck in bootloop, can't get to recovery mode - Samsung Galaxy Tab S6 Questions & Answers

My Tab S6 tried to auto-install an update yesterday (it is rarely connected to Wifi/internet). It then rebooted. Since then, it's been stuck in a boot loop.
It will display the "Samsung Galaxy Tab S6 | Secured By Knox" logo screen for a few seconds, then switch to the blue "Installing System Update" screen (with the android logo). Installing System Update gets to 28% and stops. Then the rotating icon on the android freezes. Then the device reboots and starts all over again.
Edit: the tablet is 100% stock. It's not been rooted or had any custom ROMs loaded.
I have tried getting to recovery mode, by holding power+volup while it boots. This doesn't seem to change the behavior at all. Any advice is much appreciated.

can you shut it down? try volume down and power button ? if it don't shut down, do this soon as it reboots, hold volume up and down and plug in usb cable to desktop/laptop usb port! it will boot into download mode!

I can't actually shut it down. If I start holding power+voldown right after it boots, the tablet does reboot before getting stuck at 28%. But it reboots--it doesn't power off.
I tried download mode and that actually seemed to work! Specifically, I left the tablet overnight in the reboot loop until the battery drained. Just now, I held down volup+voldown and plugged it into my laptop. I got the green "Warning/Custom OS" screen and then pressed volup to continue. The tablet rebooted pretty quickly after that (I'm guessing due to low battery) so I didn't get a good look at the download mode options.
Once I'm in download mode, can I factory reset the tablet? I don't need to preserve any data/apps/settings.

You cannot reset the tablet from Download mode afaik- You need to enter Recovery Mode to do that.
You can however, flash stock from Download mode using Odin (3.13.3 is best). If you're not confident with doing that, your best option is Factory Reset in Recovery Mode. Hold Volume Up and Power when the Tablet is booting, let go when you see the Samsung logo. The timing can be tricky, but you should be able to do it. Also, you can force a reboot with Volume Down and Power.
Alternatively, if factory reset doesn't work, since you're completely stock, you will still be covered under warrenty.

Thanks for the suggestion. I have tried this many many times. I've tried letting go of the buttons at different times. I've tried holding volup while letting go of power. I've tried this a ton of different ways, and no matter what, the tablet always shows the "Installing system update" screen. Some googling has led me to believe that sometimes, when performing a factory reset, the "Installing system update" screen shows up right before the normal recovery screen. Is it possible that the tablet is trying to get to recovery mode, but can't get past this first step?

Honestly, I don't know - I'm not an expert but I guess it's possible that the update failed and corrupted both System and Recovery.
You'll be covered under warrenty, so maybe just return the Tablet from where you purchased or direct to Samsung, could take a while given the current situation though I guess. If you have a PC, then I think the best option would be to just flash stock yourself, since that's probably all Samsung will do. Even if that doesn't work you'd still be covered under warrenty, as far as I'm aware attempting to flash stock doesn't trip Knox.

Here is solution to unbrick your device!!!

Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...
12. Feedback here and let us know if this works? For reference for others in the future...

FYI, I got in this situation, and the previous post did work for me, just takes good timing! Thanks!!!!

Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Just found a news article that there is a RGB/sRGB problem with wallpapers. It might be the problem i had.
I am adding a screenshot of the result.

Yeah, I had that kind of reboot loop from a wallpaper that I downloaded

I can get into download mode. But it kicks me out within a few seconds. Any help please

I have the same problem with a Tab S6 Lite, it is in bootloop and does not let me enter the recovery mode, I can go into download mode and I flashed the latest original firmware Android11, Android10 etc., . I tried them all but always goes in bootloop, and also the bootloop occurs only if I connect the usb cable to the PC, without any sign of life. Do I still have hopes or have I compromised the motherboard?
The reason for all this is because I had followed a guide to give root permissions with magisk, I did everything right, only that the guide was with Android10, while I had Android11 and I was deceived by the fact that in the title of the guide there was written "guide 2021"
, so I did not check the compatibility of operating systems, I was a fool, I know, I hope so much that I did nothing irretrievable, it's my son's tablet!

Did you use HOME CSC or the non HOME CSC when flashing?

Download the android 11 last rooted rom from there. You install it with odin as as a normal original rom.
Disable in odin auto reboot. After rom install, restart manually and press the correct buttons immediately to boot in Twrp and not to system. Format (not wipe) data from there and reboot to system. If you are lucky it will work..
(I hope you unlocked bootloader before try to root. If you haven't unlocked bootloader this won't work also).

Flash in odin the same rom you had. There are 2 csc files in rom, which you use 1 in odin one. Try use the "home csc". Home csc keep KEEPS your data. If you're lucky it may work. (It would work in keeping your data 100% if your rom was ok. Because it isn't you have some changes to work.).
You must try with same rom or newer.
CSC – If you flash the CSC file, it’ll perform a factory reset of your Galaxy device and wipe all data while installing a new firmware to bring your device to the same state as it was when you purchased it. Go with CSC if you want a clean installation.
HOME_CSC – On the other hand, if you want to keep your Samsung phone’s data and settings even flashing the stock firmware, you can select the HOME_CSC file.

Rooted SGH i777 Won't Boot After Factory Reset

I decided to do a factory reset on my rooted SGH i777. When I did the factory reset, the phone was plugged into my computer. Now when I turn on the phone I see the Samsung Galaxy logo and then the screen goes black (no backlight) and the phone is completely unresponsive. Is there any hope to save my phone?

US variants have their own specific fora, your thread belongs here. I've asked mods to move it for you, sit tight until they do. Generally speaking (and this is the only advice I'm prepared to give you as I don't have your specific device, but the advice holds true for all Samsung phones), if you don't have download or recovery modes, you're probably boned.
I'm sure other people will suggest a few 'longshot' things you can try which might have a very very rough chance of working when your thread gets moved to the right place though.

I'd say there is a fairly good chance...
Can you boot into download mode? If so, then it's very likely. Just flash the stock firmware with Odin. You can download the necessary firmware file from the Download Repository. If you need any additional help, just ask.

Generally, a hard bricked phone is one that exhibits no signs of life. If there are any signs of life, buttons light up, boot screen appears, screen flickers, etc, then it is not hard bricked, and is probably recoverable. But first, you need to get it into download mode.
If the phone is hard bricked, you can get it back with jtag repair from a reputable shop such as Mobile Tech Videos.
There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.

Thanks for that fantastic explanation!
This worked for me:
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
Now, how do I fix my phone with download mode?
Do I need to put a factory firmware image back onto the phone? It currently has rooted firmware that was working perfectly fine until I did a factory reset.

I would suggest that you flash the latest stock firmware, I777UCMD8 (Android 4.1.2 Jelly Bean) which you can download from the Download Repository. After flashing that you can root using the Framaroot application using the Aragorn exploit.
If you want custom firmware, once rooted you can install either Mobile Odin lite or Mobile Odin Pro and flash a custom kernel which has ClockworkMod Recovery. Following that, you can flash any firmware of your choice.
To get you started, and in case you need them, here are the directions for using Odin to flash the stock firmware (copy and paste):
How to use stand-alone Odin3 to flash firmware:
Follow and recheck each of the following steps. Do them in order listed, as some steps are dependent on previous steps. Instructions are for Odin3 v1.85 (recommended). It should work with any version of Odin, but some details, like color of items, may be different.
1.) Open Odin on the Windows Desktop.
2.) Have the USB cable plugged into USB port on the computer, but *Not* plugged in to the phone.
3.) Shut the phone off.
4.) While holding down the vol+ & vol- keys, plug micro-usb plug into phone.
5.) In Odin, you should get the yellow box under where it says ID:COM with the text 0:[COMx], and in the Message area, <ID:0/00x> Added!! where x is some number, usually 1-8.
6.) In Odin, make sure Auto Reboot and F. Reset Time are checked and all other items are not checked.
7.) Click on the PDA button. Browse to the tar file you want to install and select it so its path appears in the text edit box next to the button.
8.) Make sure the check box next to the PDA button is checked.
9.) Click the Start button.
10.) You should see the green progress bar advancing.
11.) Once the flash is complete, the phone will reboot into system.

Thanks!
With your help, I was able to recover my phone. Thank you! I will be using stock firmware. Last time I had my phone rooted, it was so slow it was unusable.

Did I just brick my phone?

So, I was off attempting to root my phone with CF-Auto-Root. I have an S6 Edge from T-mobile, and so I selected the one for the SM-G925T, which was my phone's model number. On using Odin, following all the steps from the youtube video titled "How to Root Galaxy S6 or S6 Edge!" by Max Lee at High on Android (Sorry I can't post a link, I'm too new) Anyway, once I got to the part where I was rooting, upon restart, my phone seems to be locked in the startup screen. In the upper right corner in red, it says "Recovery is not seandroid enforcing" other than that, the screen is black with some white text that says "Samsung / Galaxy / S6 Edge / Powered By / Android" With each "/" representing a line break.
When I hold down the power button, nothing happens. Did I just ruin this phone, or is there something I can do to fix it? (I fear I may have unplugged it too early... I waited ~5 minutes before I figured it was totally frozen and that I would need to do something. Hopefully that didn't ruin the root...)
Thanks for any help!

First, take a couple of deep breaths, your phone is not lost to the world.
Sounds like your stock firmware is kicking up a fuss about being booted from a non-samsung recovery.
There are several threads about this particular error already, but the general gist seems to be to get your phone back into Download Mode (power button + volume down + menu button) and flash your stock firmware back in.
That will probably remove root and clear your data though.
Do a Google for "Recovery seandroid enforcing s6" if you havn't already

This is quite normal. The same thing happened to me.
If you've got as far as flashing TWRP via Odin then it should just be a matter of booting into recovery. As you're in a place where your phone will keep trying to boot even if you power off, it's just a matter of timing.
To shut the phone down you need to hold Power and Vol Down for about 10 seconds. What you'll find though is the phone will boot up again straight away and show you the annoying Seandroid screen so what you need to do is power off the phone then as soon as the screen goes black hit Vol Up, Home and Power. Keep holding them and instead of booting to Seandroid it should boot to TWRP. If you get Seandroid just try again. You need to get those buttons pressed as soon as the phone starts to boot-cycle though.
Once you're in TWRP you can install root, and then install the kernel which will allow the phone to boot normally again.
Good luck!

Yeah, I was just googling around to see if anyone had more luck. I'm currently downloading 5.1.1 (I didn't know that Samsung changed the bootloader, so I'll have to wait for that root to come out. Oh well...) Hopefully it goes well I'll update with results once it's done downloading!

The s6 is weird. This is the first Samsung phone that when using cf-auto root it soft-bricks my phone. You have to flash recovery through odin, then root through recovery for it to work. Dont forget the no sleep fix while you're there.
Here are the steps and links:
1. Download ODIN v 3.10.6 from http://forum.xda-developers.com/show....php?t=2711451 and extract it to a folder.
2. Download TWRP v2 by eousphoros (Odin Flashable Version) from https://mega.co.nz/#!aQhTnQRR!k-M-j9...swZO3CWYi0mMtI
3. Download the latest SuperSu Beta from http://forum.xda-developers.com/apps...v2-05-t2868133 and transfer it to your internal storage on the phone.
4. Download Deep-Sleep flashable fix from http://forum.xda-developers.com/show...7&postcount=56 and transfer it ot your internal storage on the phone.
5. Put your phone into Download Mode. Power Off, then hold Power+Home+VolDown. At the warning press VolUp to continue.
6. Connect your phone to your computer via the USB cable.
7. Launch ODIN.
8. You will see the text Added! in the status panel (left side).
9. Checkmark the box beside AP and then click on AP.
10. Browse to the TWRP tar.md5 file you downloaded earlier and select it.
11. Wait a few seconds for MD5 check to finish successfully.
12. Press Start. You will see the progress bar at the top and when it's complete status window will have message "All Threads Complete (Succeed 1, Failed 0)".
13. Boot into TWRP (Button combination Power+Home+VolUp) and then flash/sideload SuperSu beta zip and then the deep sleep fix zip that you have on internal storage.
14. Reboot to system. Congratulations, your phone is now rooted.

I'm confused... When I use the Vol Down + home + power button, it boots into the normal (as far as I can tell) samsung bootloader thing (at least, the one from 5.1.1) So I don't think I have TWRP installed even. Anyway, it shows up in Odin, so how do I start loading everything? In the Files [Download] section in Odin, I see boxes that say BL, AP, CP, and CSC. Which of those do I select to load up the full backup that I got? (It's about 4GB of data with an .iso, if that makes a difference)
Edit: Basically, I have no MD5 files in the download. (I got it off high off android)

When I use the Vol Down + home + power button, it boots into the normal (as far as I can tell) samsung bootloader thing (at least, the one from 5.1.1) So I don't think I have TWRP installed even. Anyway, it shows up in Odin, so how do I start loading everything? In the Files [Download] section in Odin, I see boxes that say BL, AP, CP, and CSC. Which of those do I select to load up the full backup that I got? (It's about 4GB of data with an .iso, if that makes a difference)
Edit: Basically, I have no MD5 files in the download. (I got it off high off android)

You will not be able to flash anything in odin if youre not in download mode. If you have trouble getting in download mode, you're doing it wrong. Turn off phone, then press Vol down + power + home and dont release any of those until you see something unusual, such as an android robot. While using odin, NEVER EVER load anything in any other option than AP. As far as backup goes, I don't know what backup you made but you don't restore it though odin thats for sure, you will hardbrick your phone.

I can get into the stock Samsung download mode (light blue screen, it says downloading on it..) On the links posted in post number five, none of them worked for me... The thing is, I was trying to load TWRP while my phone was updated to 5.1.1 if that makes any difference... Anyway, it appears that the stock download mode is working, so what do I do now? (From what I've read, I can't really put TWRP on it??)

Alright, I got it working! (Hopefully this will help others get redirected to the right thread, since it took me a while to find this!) Depending on whether or not I am allowed to post links at this point, I may need to post repeatedly here, and I apologize for that, but it's all with the best intents in mind!!!
Anyway, if you do what I did, which is this:
No backup, attempt to root GS6 Edge (SM-G925T from T-mobile) with the 5.0.2 CF auto root, while your phone has already been updated to 5.1.1. It puts you in a boot loop, which really isn't fun, because it doesn't appear that you can fix it... Anyway, I went to the thread, which you can find here: http://forum.xda-developers.com/tmo...recovery-twrp2-8-6-0-g925t-5-1-1-of6-t3143002 . Anyway, what you need to do is boot into download mode (which you can still do when you are in the boot loop, just hold the volume down + home + power buttons until the device boots into the downloader screen. At that point, you use Odin, and install the file called "OF6 Stock Recovery". That should fix it! Anyway, go to the thread above, it helped me a TON!!!

This isn't really rocket science. Yes, there are different root options for 5.0.1 and 5.1.1 but this is clear in the OP when you decide which root to use.
The only things you need to consider are, if you flash a custom recovery (not the 'download mode' that you use for Odin) then the stock rom won't boot. It's not bricked but you just need a custom kernel. Therefore the steps are:
Download and copy the custom kernel and root to the phone
Boot into Download mode -Vol down, home, power - and flash recovery (TWRP etc) via Odin
Boot into TWRP custom recovery - Vol up, home, power - and flash kernel and root
Reboot
Profit
It really is just a matter of reading the steps carefully and doing exactly what they tell you.

SGS3 softbrick with lineageOS 14.1 and broken home btn

The title says it all. I have my Samsung Galaxy S3 (i9305) here next to me trying to boot up (stuck in lineage-os 14.1 loading screen), and I have my home button (hardware button) broken. With S3 you normally get in recovery by pressing home+volUp+power. I have tried ADB, but it doesn't even detect my device (i have correct drivers installed, and I think LineageOS has USB-debug automatically on. I'm also sure that my cable works with the phone and is a data cable. Disassembling the phone and replacing the home button would be an absolute "last resort" if *nothing* else works.
How to replicate:
1. Download Lineage OS 14.1 (https://forum.xda-developers.com/ga...m-unofficial-lineageos-14-1-gt-i9305-t3542012)
2. Reboot to TWRP recovery using ADB (broken home btn)
3. Install lineage (wipe, install rom, wipe cache/dalvic)
4. Restart device
5. Get booted into Lineage OS setup
6. The screen fills with popups stating that google play services/google/gallery etc. keeps stopping. (I didn't try to install gapps or such, just the rom)
7. Try to complete the setup
8. Get to the tab where you can restore files and such from an old phone using a google account
9. Click any of the options, and phone restarts
10. Aaand we are stuck in the loading screen.
I'm sure there are a lot of smarter people than me, who have had this same problem and fixed it. Thank you for your time reading this! :highfive:

Your pc does not recognize it at all or only not in adb mode?
Have you tried to connect it to pc, turn it off, And turn it on with holding both VOL + and -?
Have you tried to just hold VOL -?

Nothing recognizes it, tried with 2 different PC:s and ADB.
Just tried all methods you suggested, didn't do anything.
Also the OS was LineageOS 14.1, not hyper-rom. My bad!

Just buy USB jig and your phone should be into download mode then reflash latest stock firmware , if your home button is broken I don't recommend you to flash any custom firmware first replace your home button . Good luck

Thanks for your reply. I was thinking about that, but I would probably rather make one myself since I live in Finland and it takes about 30days or so for one to arrive from China.

J3 Hard Brick

**Please move to correct forum if not allowed*
Samsung J3 - J337P > Windows 10
Will not boot into download mode, Will not boot into recovery.
Power on > SAMSUNG J3 screen > No boot. Screen just flashes. No logo after the initial J3 screen.
Have tried every button combination / plugging USB in trick I can think of in an attempt to get to download mode.
Phone immediately attempts to boot when plugged in through USB. Im sure its just trying to display the charging screen but it doesn't even do that.
Samsung drivers are installed but do not see any USB recognition in Device Manager.
Any ideas for this newly acquired paper weight?

did you try adb or fastboot? just because its not showing in windows doesn't mean its not being seen...

i finally got it to boot into download mode by holding VOL down and the home key while plugging the usb in. flashed to stock rom with odin. not rooted but also not useless now.

I am having similar problems although self-induced. I had messed up my J3 Achieve so that it wouldn't boot. So, I tried reloading the stock firmware but had problems. I ended up loading the combination firmware factory binary. But, now I cannot get it into Download Mode to use ODIN for another firmware update. It keeps going in to the Unknown Power or Upload Mode. ODIN sees the phone in that mode but won't connect to load files.
The Factory Binary has a place to do DownloadMode, but it says Enter Password. So, I have no idea what the password would be and coannot find any documentation on the service firmware (assuming they use this at the factory to test). I can get to recovery, which will let me load from SD or ADB. I have barely used ADB and couldn't get it to connect. So, I need some guidance. Hopefully I didn't totally brick it, although I only paid about $60 for it and can get most of that back for parts.
Ideas?

OK, I got the stock ROM reloaded - finally. Now, however, I'm back to the problem that started all of these problems in the first place. When I flash TWRP, the phone won't boot. It shows the initial screen and then goes into a mode where it is either black or dark gray (momentary flashes like it's trying to do something). I've verified my version of TWRP (released in October). Any ideas how to flash this one correctly?

I know you've fixed this but the way to get it to download mode when you get the upload screen is by holding down vol - , power and home button. Once the screen goes blank continue to hold down the home button and let off either the vol- and hold the home button, or hold vol - still and home button. It will then boot into download mode.

Help with S6 Edge please!? I'm going insane!

Hi guys, I've owned an S6 Edge in the past.
Due to my fondness, I purchased another one last week (Arrived today).
Damn, it's in mint condition! I purchased it knowing it wouldn't boot.
The guy had a picture of download mode stating it needed firmware/rom.
Not a problem I thought! I went through all this with my past S6 Edge.
I got the phone, got it out the box, thought hmmm... Won't boot, must be dead!
Plugged it in (First issue) I didn't get a charge screen, but a S6 Edge Powered by Android (bootloader screen)
Anyhow, I've flashed the latest stock firmware, continues to bootloader screen and sticks.
I've flashed TWRP and I can enter TWRP, flashed multiple custom roms, still stuck at the bootloader screen.
Flashed the stock firmware with re-partition and a PIT file, still stuck at the bootloader screen.
Any help? Is this phone done for or am I missing something?
This would have been my daily driver after smashing my S9, needed a non contract phone. I LOVED my old S6.
It is a G925F, not sure what firmware it had previously, haven't had a single successful boot.

Try to install Android 5 firmware on it.. And when it's booting up (SAMSUNG LOGO) Click Power+Volume down button.. When it's powered off.. Quickly, Click Power+Home button+Volume up and you will be booted to Recovery Mode.. Click wipe data, cache then reboot system.. Wait till the phone boots completely.. Then, you can flash twrp and custom roms... Tell me if it worked..

Hi mate, I've tried installing (and successfully) Android 7.0. It stays on the 'powered by android' galaxy screen.
I can get into TWRP and install custom roms successfully, just stays on the said screen again.
Also, might be worth noting, when I plugged the phone in to charge it just goes to the same screen mentioned.
If I hold Power and Vol Down while plugged in it will go to the battery and the thunderbolt, just no animation.
Also LEDs not working.

Just do it...Dont plug your phone when ur doing power+volume down thingy..Android 5 firmwares are a little bit different than marshmallow and nougats..So just flash it and you will see the profit

Also, won't I get a bootloader error while trying to flash because it is a lower version?

If you try the Odin3 flash tool?

How long are you leaving it on the bootloader screen after flashing stock? First boot can take 15-30 minutes sometimes

hey just do the following...
Hi...if your problem is still active - not solved! Here a little Note for you that maybe help you to get s6 edge running again.
First you need to start Odin 3.12.03 with Admin rights!!!
Then you could use the Firmware from my Google Drive if you want. Its the German Variant with CSC-DBT
https://drive.google.com/file/d/1pDybynK6_Huu-vjM_azIjgz30IIhlEAP/view?usp=sharing
If you want to use SamFirm by your own. Keep attention that you check the "Binary Nature" !!!!!!!!!!!!!!!!!!!!!!!!!!
If not...its just 1,9 Gb and dont work
If yes...its over 2,3 Gb and work fine
shutdown phone with Vol- and Power (keep holding both)
then start into downl mode with Vol- and Home and Power (keep holding all together)
connect phone to usb
after flashing rom the first start could take up to 10-15 mins...not more on stock firmware
if the first start is done and your in the screen where to type your sim pin
power off the phone and unplug usb
start into download mode again
reset Odin and select the twrp.zip into ap
plug usb again
flash twrp with odin
phone restart automatically...just wait the minute
then shutdown and start into twrp recovery with Vol+ Home and Power (keep holding all together)
so good luck man
