Is my device fully bricked? [Samsung Galaxy Tab A 8.0"] - Android Q&A, Help & Troubleshooting

Hello. I have tried to install a custom recovery (TWRP) on my Samsung Galaxy Tab A 8.0" (SM-T290) today, however, it has not exactly gone to plan. I will run over exactly what I did, and what troubleshooting steps I have taken so far.
I downloaded this version of ODIN: https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/
I unlocked the bootloader through the bootloader menu and enabled USB debugging after the tablet had turned on.
I downloaded and used the latest .md5.tar TWRP file from here: https://forum.xda-developers.com/t/...-2-for-2019-galaxy-tab-a-8-0-sm-t290.4185235/
ODIN Successfully flashed TWRP and the device rebooted. I attempted to get straight into the recovery by holding volume up, however, the screen remained black.
The tablet now cannot boot into recovery, download mode, etc, and only the backlight of the screen turns on. The tablet does eventually "boot up" and give the little vibration, at which point my computer recognises it, but I cannot see any files on the tablet. I can also see the tablet with ADB using the command "adb devices", however it tells me the tablet is "unauthorized", meaning I cannot use any ADB commands to attempt to reboot into recovery, download mode, etc.
I have tried disconnecting the battery and just powering on with the cable to no avail. I am assuming the device is fully bricked at this point, however, I would be appreciative if any possible solutions could be suggested, and if where I went wrong can be pointed out so I do not make the same mistake in the future.
Thanks in advance.

It's always risky to apply mods.
To get rid off of all mods you applied re-flash tablet's Stock ROM.
If this doesn't work for you then take it to authorized service center and let them try to fix it.

They never fix anything. The only thing they do is charge you an absurd price and replace the motherboard or the entire tablet.
I'm on the same boat. Tablet can't get into download mode, just shows "This device has unauthorized software on it and is locked". Tried all possible button combinations to no avail.

[Q]Help! Verizon i905 will not boot up.

I know there has been other treads about this before but none of the suggestions seemed to work for me. I searched and searched and I'm just not finding a fix. I hate to do these posts when an easy answer is right there but I just can't figure it out and it's killing me. So here it is:
I just got this Verizon Galaxy Tab that would not come on - only showed the battery charging icon. I just charged it over night and it came on once. However, processes kept shutting down. For instance, when I went into settings and tried to connect to my wifi network, the whole process would just close down. So I let it get to about 40% and reboot it to download mode (there was no recovery). I found the correct .tar file for it and flashed it with ODIN3 v1.85. It completed successfully but now it won't boot past the Samsung splash screen. Once the splash screen comes up, it will just go back to the large battery charging icon in the middle of the screen.
Then I tried the other option where you get into recovery and nothing happens at all. The screen is backlit black (you can just see light around the edges of the screen) and nothing ever happens.
So now, it's just charging but it seems to charge very slowly. I was wondering if this is a battery issue or some strange sequence that needs to be done. It seems to be at about 40% again. Any other suggestions would be appreciated.
These are other things I've tried:
hold the power button down for 30 seconds
Hold the power button down while touching the screen
More suggestions would be appreciated.
Now the tablet is fully charged but it still gets stuck on the splash screen when trying to boot up. Still have no recovery. Also, I'm not able to find a PIT file to re-partition. Can someone tell me how to get the stock recovery back at least? I've been looking but I can't find a file to flash for the recovery.
Same problem
Hi, I have the same issue basically. I have the Galaxy Tab SGH i957D 8.9 (TELUS) and flashed it to root last night, now I have the same problem. Except I have CWM installed, I was able to install that AFTER I locked it up. Help from one of the GURUs here would be great. It's obviously a problem caused by flashing it.
So try flashing with CWM, at least you'll have a good recovery on it. If we work together, we may be able to come up with a solution for our dilemma. I don't believe it;s a major problem, I had the same issue with my captivate phone when trying to CWM and Cyanogenmod, and I got it working perfectly, so there is hope.
I have tried the stock rom, rooted rom, and a couple of others, but still can;t get past the splash screens. Left it overnight trying to boot, and all it did was kill the battery. I can;t even turn it off, it just reboots every time I try shutting down. I CAN get to download and recovery mode though, and flash it all I want with Odin 3.7 and 1.83, just never boots past the splash screens.

Thanx for the reply. As you can see, I've been around these forums for a long time and usually I'm able to work it out but this one has got me stumped. Just wanted to ask you if you have tried to flash a custom ROM in Clockwork? Also, did you go through unlocking the boot loader befor you flashed it? I did not because I received the tablet in this condition. I tried to flash clockwork mod but I get an "invalid file" error in Odin. Once I flashed the stock recovery and it worked fine. But after reflashing the stock rom, the stock recovery is gone now. Do you have a link to the files you used? I'm thinking that the stock recovery is messed up but I can only find that one file.
no I haven't tried flashing through CWM, as I wasn't trying to flash originally, I was just rooting and going easy on it, then it wouldn't boot, so I wasn't prepared and now can't add files to my SD drive.
I didn't unlock the boot, as none of the instructions I read mentioned it (rooting was all I was trying to do).
I don't even have a stock recovery either, all I have is CWM and TWRP.
I'm going to try mounting it in Linux and see if that makes any difference to put roms on my SD drive, as windows doesn't like it anymore, except through Odin, where luckily it seems to work fine... For now.. lol
Fixed!!!

I'm glad you got the right firmware and fixed your tab! But this site does not list a firmware for the SCH–i905 anywhere. Unless the Verizon Galaxy tab has an alternate model# there is no firmware on the site for my device. Oh well, at least one of us got tablets fixed. Congrats!
Download mode issue.
What recommendations do you guys have for a tablet that will not recognize in download mode?
I accidently flashed a bootloader and had auto reboot on - couldnt flash kernel and modem in time.
My tablet fully boots up, (rom manager says cwm is installed) as well as when i boot into recovery its completely black.
My main concern is that download mode is not recognized. it was previously working prior to installing the bootloader.
What can i do to fix this issue?

Can you start by giving as much info as possible about your tab, make model# etc.
can you actually get into download mode? Power button and Volume down button till it boots then release pwr.
you may have bad drivers on your pc. I had this problem with my phone when I installed CM.
get into DL mode and then start Odin and hopefully you will see the Com port attached.
then in PDA load the stock rom for your tab.
hopefully at this point youll be all set.
if your tab is fully functional, then try just flashing CWM or TWPR to your tab. I found with mine that CWM works best. I like TWP better for looks and the touchscreen functionality, but I found it gets a bit flaky after a few flashes, where CWM seems more stable.

give me all your info for your tab, make, model.. carrier etc. as much as you can, and I will see if I can find any stock roms while doing my searches. 2 sets of eyes are better than one...
So i have a sch-i905, 4.0.4 - I CAN boot into normal android
I flashed a bootloader last night and had auto reboot ticked. was not able to install the modem or the kernel.
I can get into download mode without any issues,but now download mode says "waiting for cable" and is not recognized by pc as it once was prior to the flash.
I can also get into recovery but its completely black ( assuming due to no kernel flashed )
I can get into android normally, but cant fix firmware through download mode, and recovery.
Please help :X
side note: rom manager says twmp and cwm is installed, though i get no display in recovery only blackness
if i can get download mode to work again or get cwm to show up i can fix it, but dont know where to go from here.

I don't get it. First, you can't flash a kernel using Odin. Second, your tab won't even be able to boot without the kernel.

If you can get into DL mode, then its probably just an issue of drivers on your pc. Download the samsung drivers and reinstall.
Then put your tab in dl mode. Then connect to the pc with cable, try a different usb port than before.
Then start odin, if you get the Com port showing up in the status box, then flash CWM recovery to the tab. Then start over with what you are trying to do. But I can almost garantee its an issue with drivers on your pc. I had the exact same problem with my phone when I did it,
and fixing drivers was the issue. I wss stumped for a long time on that issue. If that doesnt work, look into Heimdall flash utility or Kies and go from there.
Hope this helps. Or at least gets you on the right track.

dont think its a driver issue.
it was working fine in download mode prior to me flashing a bootloader.bin, and yes you can flash a kernel.bin through odin, as well as a modem.bin.
I was in the process of installing cwm this way when it happened.
I can get into the os, i can get adb working fine, recovery is just a black screen though it goes into it. and i can get into download mode still, just stuck at "waiting for cable" no interaction with device manager

Ive tried another pc as well. I dont believe its a driver issue as there is 0 interaction in download mode with device manager. but prior it easily was detected in odin no issues.

Ok... Im getting confused here... You Can still flash with Odin? Then you can install a new recovery on it. If device manager on the pc is not working, then you probably have a corrupt install, or the wrong rom file for your particular tab, and the usb drivers arent correct for your tablet.
Personally, I would start by downloading a stock rom file and return the tab to factory before starting anything, so you have it working as it should before continuing further.
If you DO HAVE a stock rom, maybe you could pass it along, i believe shawndh who started this thread is in need of one for the same tablet.

I cannot currently get download mode to recognize anything. just keeps saying "waiting for cable" thats why i cant do anything in download mode. It was currently working prior to flashing the bootloader through odin with the "auto reboot" accidentally clicked.

Oh... Well then it is beyond the scope of any problem I have encountered, or seen a solution to. I thought you could still connect in download mode.
Can you change usb debugging mode in tablet settings, that may enable you to connect? If not I dont think I personally can help, as your posts read like you could still use Odin.
On my phone, (galaxy S) nothing would connect after I messed up, but could do things with Heimdalls utility. See if you can connect with that. Worth a try, it does the same as Odin, but connects differently somehow.

i even went as far as getting a brand new cable to see if it was my cable still same thing. No response in download mode for either pc's ive tried.
little stumped....
possible clues: when tablet boots up, it boots up to a bright black screen, only once it completely boots up am i able to see my display properly.

Thanx for the reply. I have the SCH-i905 32gb Galaxy 10.1 tab. The carrier is Verizon. I've spent days looking for another download source but I can only find one - there's a link from this site. Others have posted that it did restore their devices so I'm thinking that there are some bad clusters that need to be quarantined but I can't even find a tool for the Galaxy Tab that will do or check for that. I'd appreciate it if you could take a look though. Thanx.

Are you connecting to a USB port that is on the motherboard of your computer? Mine will only recognize my tablet with one port. The other ports are not recognized at all by ODIN.

I don't think its a cluster issue, just a bad flash previously. But you'll see from the link, yours is also known as the P4vzw. Well check the link and make sure that's your tab that I found. Then have a look at ALL the files for that tab.
Have you seen/tried this one... here's the thread STOCK ROM FOR YOUR TAB...
forum.xda-developers.com/showthread.php?t=1342995
Here's just the file.
http://goo.gl/XPMXv
Try flashing CWM recovery to your tab, and try a file from cyanogenmod
http://wiki.cyanogenmod.org/w/P4vzw_Info
Or just try the CM ROM first maybe and see what happens. I don't remember what you have for recovery. There are a bunch on there, but all nightly that I saw, but even that would be better than nothing for now if it works.
I'm still looking, but I know what you're saying about few and far between. I think they all are for the tabs. Let you know if I find anything else.

[Q] CMR boots, but main OS no longer boots

Hi, first of all I love this forum, this is my first time posting here but I found it indispensable when I was doing Android development-related stuff. However I've now managed to do some damage to my phone and need some expert advice!
So I was following the instructions on the CM wiki (I can't post external links yet but the address of the page is /w/Install_CM_for_i9100) for installing CM (I'm using a Mac). I got my phone into download mode and used Heimdall to flash ClockworkMod Recovery. This is where I think I went wrong: Heimdall found the phone fine and transferred everything, however the progress bar held at 'full' for about 5 minutes. After a while I thought it must be done and just doesn't have a confirmation once it's done, so I unplugged the phone and rebooted into ClockworkMod Recovery. Recovery boots up fine but when I try to connect using ADB the phone can't be found. When trying to boot up normally I now get the warning triangle below the Samsung Galaxy logo and the phone just turns off. Booting into download mode, Heimdall can no longer find the phone when it's connected. So, since I can't boot into my stock OS, and I can't transfer a new OS or re-flash CMR, does this mean my phone's bricked? Or is this a known issue with a fix? I've tried the search function on this board but can't find this exact issue.

[Q] Stuck in boot loop, exhausted almost all optons

LG Escape running 4.1.2
here is the progression of events:
1. rooted device
2. root seemed successful and no malfunctions
3. backed up all apps and system data with Titanium backup
4. the lg escape has no way to unlock the bootloader, so I tried various other methods. one of which was entering recovery mode via terminal commands. this is basically a hard reset, and it wiped all my data
5. I restored all my apps and data from my external sd card with titanium
My best guess is this is where something went wrong
6. upon restoration it prompted me to reboot the device
7. reboot passes manufacturer logo, but resets when AT$T logo appears
8. as stated earlier, there is no way to enter recovery mode during boot.
9. there is a hard reset during boot, but mine will not work, as it requires touching buttons which do not seem to be active in my stage of the boot sequence
so, I understand this does NOT mean my phone is bricked, but I don't know how else to get it to boot back up, or what is even causing the boot loop, as I DO NOT HAVE ANY CUSTOM ROMS flashed. any help here is very appreciated!
EDIT: so I have attempted to use adb on my pc to reboot into recovery from there, but it occurred to me that while I was in recovery the first time, I never checked "usb debugging". as a result my adb console commands cant even see my device. any way to turn on usb debugging while locked in a boot loop?
also, I can get it to enter download mode. I was hoping I could just reflash the firmware to it without needing to enable usb debugging, but have no clue how to do that while locked out of the phone.
I realize this is a very specialized set of questions, but it is necessary to ask here as the most people will see it. im open to any ideas

i have now tried to flash the firmware while in download mode using a less than legitimately obtained lg R&D tool. however, i need V10F_00.kdz and i am facing a bit of censorship. any kind soul willing to host this file on dropbox or similar so i can download it?
Usually devices have a button combination to press when powering on to get into different modes. Maybe try searching for the button combination of your phone on Google? Try ' lg escape button recovery ' ?

*URGENT* HELP! File pulling with ADB

To start off, I suffered, what seems to be a common problem, of the fingerprint unlock on Samsung Galaxy S6 Edge randomly being unable to recognise my fingerprint. Followed by my back-up password not being accepted. Unfortunately, I turned off my data and wifi before the phone locked so the problem doesn't seem to be able to resolve itself unless I Factory Reset the phone.
This i am happy to do as long as I can find some way to retrieve the media files from the phone (just pictures and videos). I read up and watched some videos where some people were able to use ADB through Recovery Mode or Field Test mode, and pull the files from the phone. These people however were using older models of Android phones but I decided to read numerous pages etc and go ahead and try.
I set up everything (I believe) i needed on my Mac Book pro in order to use the Adb Terminal. However when I tried to connect my phone Adb couldn't detect my device. I then decided (after reading somewhere to do so) to press "Apply update using ADB" on the Recovery menu. Again, Adb did not detect my device.
i left this screen up on my phone which resulted in "dm-verity verification failed..." appearing at the bottom of the screen. It then switched back to the Recovery menu and continues to show "dm-verity verification failed..." at the base of the screen. Now when I try and power up the phone normally, the start up screen just repeatedly flashes and it goes no further than that.
Im not completely brain dead when it comes to this stuff but I obviously don't fully understand what I am doing, So Im wondering if there is a genius out there who, even after what I've done, can help me pull the files from my phone before I have to Factory Reset!
The problem is, that you don't have the ability to use adb pull through the stock recovery. This kind of thing can only be done via a custom recovery like TWRP, CWM, or Philz. Now that it's not booting, pretty much the only thing to try is to install a custom recovery and boot directly into it before it tries to restart. Make sure you find one for the correct variant of your phone. If yours is a VZW or ATT version, you're in trouble because they don't have custom recoveries like that for them.

Samsung Galaxy S4 i9505 is not booting to android or recovery

Hello, i have encountered a problem with my rooted SGS4 i9505 (I'm new to xda and don't really know if this question is supposed to be placed in here so forgive me for that)
I have been using this phone with a nightly build of cm13 6.0.1 and there were absolutely no problems and it was great but today i wanted to update to another nightly build so i downloaded it and in the developer's option i checked that the phone would also get a custom recovery that, comes with the rom i think, installed and it rebooted to update the rom. Then the screen just went black , i waited a minute but it still didn't boot so pressed down the power button in hope to boot up in android again but instead it started booting into recovery but after the blue text in the left-top corner appeared the screen went black again. If i plug the phone in to charge it starts vibrating with intervals of about 3-5 seconds and never boots, no logo or even text is displayed, the screen is just black.
So i can't boot into android nor the recovery, only in download mode, and odin also doesn't recognise the phone
If someone could help that would be very much appreciated, thank you.
(I'm not a native english speaker, so please forgive me if there are any mistakes)
If you can get into Download Mode, then it's a matter of making sure the correct drivers load for Odin to see it. Check your Device Manager on your PC. Even if the PC has connected with it before and loaded the correct drivers, sometimes you have to manually point it in the right direction again. Messing up the recovery should not affect the Download Mode. Once you get the computer to recognize it again, then I would use Odin to reload TWRP recovery and you should be able to boot into recovery and do what you need to do. If recovery is still messed up, then you might need to reinstall the original firmware and start over.
