J3 Hard Brick - Android Q&A, Help & Troubleshooting

**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.

[Q] So... I bricked my phone =/

I'm stuck at the Vibrant boot screen, and when I try and plug it in the USB and user adb devices, it doesn't recognize it. I've tried Droid Explorer, and I believe my Vibrant is hardware locked.
Any ideas? Sorry to make another thread but I couldn't find a solution to anyone with this problem.
What did you do to it?
Search around the forum, there is a post talking about getting into download mode with hardware lock phones.
If you are able to get into download mode you can use ODIN to install stock ROM again.
Something incredibly stupid, I tried flashing a custom kernel on the stock ROM.
Yeah that's all I've been doing. I've read all the threads I can find about how to get into download mode with a locked Vibrant, but no luck =[.
Launch Odin
Plug in USB to PC not the Phone
Insure Phone is off
Hold down Vol +/-
Plug in cable
Hold down +/- about a second
Walla you are in Download and should see a yellow triangle
Have you tried turning off your phone and turning it on holding down the Vol +/- and power and entering Recovery mode?
From there you could flash a nandroid backup if you made one that is. Sometimes I get lucky if its in the regular recovery and use the Re-do package option and sometimes I get it up and running.
Of course it just depends on where you are in your flash and what your phone will allow you to do.
Tried that oh so many times, and it just wouldn't budge.
At first I was actually able to run ADB commands... and before I had read more about it, I booted it into recovery (instead of dl mode fml) and wiped cache/user. I already tried reflashing zips to see if CW would start up so I could restore my nandroid backup I had made.
Anyways, now ADB doesn't even recognize the phone. And I tried to install the drivers on my laptop to see if that would do the trick, but I'm still stuck.
Edit: I just tried to use the method you gave in your first post again and I just get the battery charging screen. Thanks for trying to help though, I appreciate it.

Flashed Wrong Recovery - CWM and Download mode don't work

I tried to Unroot my Galaxy Tab 10.1 LTE last night and think I may have bricked my tablet. I used the instructions here on the XDA forum which had a link to all the Stock ROM's in one place. I got the most recent one and the only one for USA but it said it was for the model 7510. I didn't think that would be a problem since the USB drivers I installed on my PC were also labeled as being for the 7510 and they worked.
This tablet is the SCH-I905. Now I can't get it to boot at all. Gets stuck in a boot loop. Shows the Samsung logo, then resets and does it again. I can't get it in recovery mode either. Goes to a black screen and hangs.
Using the normal process to get to Download mode doesn't work. Holding Power and Volume Up, then letting go of the Power button, then pressing Volume Down and then Up. That's one weird thing. I can get to the option screen that shows the Download and Recovery mode options. Normally I would hit the Volume Down button to select Download mode and on the screen it says to press Volume Up to continue or Volume Down to cancel. If I press Volume Up it goes to a black screen and hangs. If I press Volume Down I get the Odin Download screen that says Waiting on USB cable.
That screen doesn't look the same as what I normally see but I'm not sure what's different. I didn't memorize each line of text. I just know there's not as much text there as there usually is. My PC will not recognize the tablet no matter which USB port I try to use and the tablet doesn't recognize that the USB cable is plugged in. I had no problem with the USB connection before I flashed the 7510 stock ROM.
So, if I cannot get to recovery mode and I can't get Download mode to work so I can use Odin to flash a different rom then is this thing bricked or is there something else I can try? I am about to try using my laptop and its USB ports but I don't think that's going to make any difference.
BTW, I have since found the correct 'stock recovery rom' at droidbasement.com and downloaded it to my PC. I just need to get on the tablet somehow.
Many people have your problem. I have my Lte verizon bricked as yours. The problem is demaged bootloader, only nvflash can fix it but actually our bootloader is locked and we need a hex key called sbk. At least we have to wait that somebody hack our tab from the basement. For now we can only search and share result.

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)

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.

Download Mode note getting

Hii Friends,
Im using samsung mega 6.3. (GT-I9200)
im trying to update my mobile via odin. but when i try to enter download mode its not entering .
Please help me
(Volume down + home button+power button )
Dag_Nab.It
S/G MEGA 6.3 (AT&T-US) SGH-i527~GT-i9205
I have the same issue with my device not entering Download Mode. My device will ONLY go to main screen asking for password, which I no longer remember.
please help us
Still_Kicking...
VolumeUP+Home+Power, still getting 'no response' while holding all three down and releasing at start up.
*i forgot to mention that after StartUp, on the Enter Password request page, only the Power button operates. the VolumeUp, VolumeDown, and Home buttons do nothing. I have to press Power button after the screen has blacked out to bring-up the Enter Password request page again.
Today, I installed an old SIM card (SIM not provisioned MM#2) is displayed. I'll have to research this for the meaning as this is a first for me.
This time I held VolumeDown+Home buttons throughout the StartUp process. This time, on the Enter Password request page, in the lower left corner, Safe mode is stated. Anyone have some tips on what we can do while the device is in this mode as I have yet to read anything on Safe mode for any of the devices listed so far?
TO ENTER Safe mode:
Hold Power button until device starts up, release. Now hold down VolumeDown+Home buttons until Enter Password request page shows. The device should now state that its in Safe mode in the lower left corner. Please take note that this is on the S/G MEGA 6.3 (AT&T-US) SGH-i527~GT-i9205.
Galaxy Mega 6.3/ Black screen after ROM Flash
A friend of mine gave me his Galaxy Mega 6.3 as when he previously did something with the phones software, he messed something up and lost imei numbers, wifi and bluetooth wouldn't work however the phone would still turn on. Just like an MP3 player.
I struggle around a day to get this phone into download mode in order to flash its factory rom and i finally got the phone to download mode, i flashed the correct I9205 stock rom on and now the phone wont turn on.
No buttons light up including the blue LED at the top. The screen turns on and back off after a few seconds. No logo appears, but the phone does respond to the power button. Its like a bootloop but it loops before it gets to any sort of logo screen. I cant seem to launch to any sort of safe mode, recovery mode or download mode and the phone is not detected on my computer.
Any ideas on how to get this backup and running.

Did you check the PDA, CSC, and of course the md5 to make sure you had the right Firmware(ROM)? Where did you download it from?
How did you get the device into download mode?

I managed to get the device to download mode via the normal method of pressing volume home and power however it doesnt always work and it just restarts continuesly. I got the rom from sammobiles or something like that and i believe its the correct one. I have tried several other roms that is for mega 6.3 but no hope. However i did manage to get twrp installed. Do you by any chance know any os that you can link for me that i can install directly and only by using twrp installation?

There is LineageOS ROM with RR Remix. I have heard that you have to use Kies before you can use Odin3. Sorry for the late reply.

Tab S6 stuck in bootloop, can't get to recovery mode

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!!!

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.
...
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.

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

Hi,
Really need your help, after I updated my firmware using Odin, updated BL, AP, CP, CSC, my tab cannot boot up stuck in logo. Doing the Power + volume up leads me to different screen now. I cannot access recovery mode or download page anymore,
What must I do? Pleasssee help. Added the pic, after doing hard reset (power + vol up)
I cannot connect back to Odin also. Always setup connection failed.
Please help. Really messed up big time
Just a thought... Can this be restored from service center?
Thank you in advance.
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?

Try to install a castom rooted rom which has pre installed also Twrp.

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).

Wiping cache partition in Recovery and reflashing the firmware are basically your only 2 options

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.
