Tab T807N gone haywire - Galaxy Tab S Q&A, Help & Troubleshooting

I am searched this forum for about the past four nights trying to figure out what is going on with my tablet. Long story short my boyfriend could not figure out the lock screen code while I was asleep and restarted the tablet I guess in download mode and it was stuck there. It had the little green guy and said downloading do not do anything. When the battery finally died it started to reboot but then just kept going in the boot loop. I was finally able to get into it and it will boot up for the most part but the three buttons at the bottom won't work the back button the home key and the recent apps key. They don't light up even though they're set to be lit all the time now. I took out the SD card which had evidently become completely erased when he was doing something to it. Also it doesn't recognize that the SIM card is installed although it is installed and I made sure it made the click sound when pushed in. Now when I press the power button volume up plus home key to try to go into recovery mode it doesn't do anything. I was able to boot it in safe mode but that didn't help me either way.
Any advice?

He's mucked something right up.
I suggest putting it back in download mode and flashing the latest firmware with odin.

[Q] Can't boot or go into download mode

Hey everyone,
My phone won't boot, go into recovery or go into download mode. I was on FrostyJB but was going to change to a 4.2 ROM, so I was going through my normal backup process. I set Titanium Backup to backup all apps and then left it for a while. When I came back later to pick up my phone I checked the lock screen for the time but did not unlock it. About 10 minutes after this I attempted to wake my phone, but it would not respond. I pulled the battery and attempted to reboot it. The soft keys lit up but the screen stayed black. When I try to put it into download mode it just vibrates occasionally. I was switching ROMs also due to the fact that my phone was filled up with "system data" and I needed the storage for my trip to Colorado in approximately 6 hours now. Any help is greatly appreciated and if its not too much trouble please respond quickly because I'd like to have a working phone during my trip.
Thanks in advance!
Ok, so I've managed to connect it to Odin by pressing the buttons blindly (the screen never lit up). I flashed a new recovery and rebooted it but no cigar. I assume my screen is broken somehow. I guess I'll take it to a Tmo store when I get back from vacation, it's a shame I won't have it for the trip >.<
Did you try pressing volume up + power + home key to get into recovery? Also if the soft keys lit up while trying to get into download mode then it may still be in download mode even though the screen is black. That can happen due to various things. To be sure I would connect it to a pc and see if Odin can identify it. If so then you can try flashing it back to stock and see if that makes any difference.

I just had very similar situation backing up system on TWRP (fell asleep and phone completely discharged while in recovery).
1)Open ODIN on PC,
2)Pull battery out of phone.
3)Connect phone to pc w/ usb
4) Put battery in
5) hold down volume, home button and power button
6) Took me immediately into download mode
..good luck

[Q] Phone possibly hard bricked, need help

So I'm running CM 10.2 android version 4.3 and I started to notice that when I pressed the power button, it brought up the reboot menu instead putting my screen to sleep so I downloaded the newest nightly and figured it was probably just a bug and went to flash the latest nightly. Upon reboot, my phone got in an infinite bootloop so I pulled the battery, let it sit for a minute and then held the power, volume up and menu button to enter recovery. I got the blue words in corner that you will normally see when booting into recovery, then saw the S3 screen that you'll see right before entering recovery, however, my phone started rebooting again constantly vibrating etc. So then I decided to try and get into download and flash back to stock with Odin. So I entered download mode, pressed volume up on the confirm screen and then it entered download mode and then immediately rebooted and wouldn't stop. Is my phone bricked? I'm wondering if the power button is broken since when in download mode, it reboots which normally occurs when you hold the power button in download mode. Sorry for the long description but just wanted you guys to know what I've done so far and am experiencing. Any help is appreciated. I've been rooting phones from all manufacturers for years now and I'm out of ideas at this point. Thanks!
Definition of a bricked phone: A completely unresponsive device which doesn't turn on at all. Doesn't vibrate upon start up and doesn't have any signs of life.
You most likely have a jammed power button as that has been the issue with the GS3. Not a brick.
Clearly not bricked as the first reply explained. And for the love of god, please use some white space (paragraphs) next time.
If you think that a button is jammed, see if you can physically unjam it without causing damage. If you believe that the flash may be messed up, the mskip's Samsung Toolkit may be able to reflash a known good ROM even with a stuck button. And look into some of the button remapping apps like the aptly titled Fix Broken Power Button app.
Good luck.

Soft brick, but can't access recovery mode

Hey there, so my phone randomly decided to stop working today.
Whenever I put the battery in the phone or plug in the charger, the Samsung screen loads then nothing. This all happens without me pushing the power button btw. Then the power button doesn't work, nor can I access recovery.
Like I mentioned, this all happened very suddenly and unexpectedly. I haven't flashed a rom in awhile so I'm not sure what caused the problem. One tidbit worth mentioning is that my phone would randomly reboot on the rom I've been using, but it wouldn't happen too often.
Any help would be greatly appreciated. Not exactly sure what I should do in this situation. Thanks for reading.

try to be quicker to access recovery, power off the phone. then press the power, vol up, and home then AS SOON as you see the blue text on the left top side of the samsung logo screen let go of the buttons, it should boot into recovery then wipe data factory reset and reboot.

flash this recovery attached with odin by booting into download mode via power vol down and home, wipe data factory reset and reboot
http://www.androidfilehost.com/?fid=9390212717148635222 (recovery)
http://www.androidfilehost.com/?fid=9390275921635705049 (odin)
place in pda with only f. reset time and auto reboot checked. it SHOULD only take about 10 seconds to flash. as soon as your phone reboots hold the recovery combo and it should go to it
I can't really access download mode either.
I'll get to the screen that asks if I want to go into download mode, then push the up on the volume rocker, get to the next screen, but then it goes black about a second later.
Thanks for all the help so far though.

kinda odd. never had that happen before. ,maybe you could try to reflash the download mode into your phone using this method
http://forum.xda-developers.com/showthread.php?t=2369125(make sure you use a debrick.img http://d-h.st/iEy for att not sprint BTW)
or use a jig. since your phone can still access the boot interface.

Have you done this and then connected the USB to see if ODIN will recognize the phone? it's entirely possible that you are getting into download mode, but just can't see it..
It's certainly worth a try.

r800i LUPUS Softbrick

I've dug around trying to find a similar problem here and on google, so my apologies if this has already been addressed.
The problem originally began when the game pad stopped being responsive (or at times took multiple presses to get a response) and after no luck troubleshooting it, I tried to reset from clockwork recovery.
Ever since my phone no longer boots. It just sits on the LUPUS wolf logo (I do not recall exactly which rom I am running, but I hope this helps) and at first I thought it was your normal "this can take a bit" first boot, but I've let it eat the whole battery and it never gets anywhere. I've tried to prompt the phone to boot into both custom recovery and d/l mode and neither get me anywhere. Any suggestions?

IMHO, it looks like faulty slider flex cable (exact same situation i had, but i was able to enter recovery after 2 minutes of logo on screen)
Try to power on phone with slider open.
If you can enter in recovery mode with "volume -" (if it light blue led or vibrate) and see is d-pad is working.
Sorry for the delayed reply. The notification went into my spam folder :/
Alright, I followed your steps in two ways. I opened the slider and held both the power and the volume down till I got the buzz buzz and the LED blinked green once and continued to hold volume down till I got the LUPUS logo. No luck. I did mostly the same thing the second time but I held the volume down for 3 minutes with the same result. I still have yet to make it back into recovery.

To be able to enter recovery, it is not "holding volume-" while powering on phone or keeping it pressed.
Press power button (and it should vibrate), and release it.
When blue led is on press and release vol- button many times untill you enter recovery (don't keep it pressed all time)
Ah, you are absolutely right. I've never entered recovery like that on another Android before. I loaded up the "near perfect" rom and my game pad seems to be working for now, so it appears I am back in business.
How problematic is it if my slider flex cable is going bad? Will it permanently fail eventually?

NOOB: hard bricked op3, volume up button hasn't been working

First off, I did do a search, but as far as I can tell no one has had this problem so far.
This is all after modding using a tool kit: (i can't include the url but it is the toolkit by neisor on the oneplus forums)
tldr: phone stuck in bootloop, computer wont recognize the phone, maybe because it keeps shutting off and then booting to the 1+ logo, then shutting off again, would drivers help? what can I do about the volume up button?
So for a while my volume up button hasn't been working, and the mega unbrick post shows that I need to hold the volume up button for at least 25 seconds and while holding, plug my phone in. I have also seen some posts that say the volume up button could be a software issue, and the button itself could be working, and it is just not registering, as well as someone saying that you could take the back off and manually press the button, instead of using the bar on the outside of the phone (would this work?). I have gotten the button to work in the past by pressing the volume up button to the side instead of straight in, but I haven't been able to get it to work since my phone got bricked.
Another issue: my phone is stuck in a boot loop, I can't access fastboot, and I'm unsure of recovery because my volume up button is not working. would it be worth it to deal with the constant vibrating to try to get it to recovery?
I have been able to shut the phone off by holding the power button for something like a minute and a half, though.
This is my first post, and if I have broken any rules I am very sorry, but I need help and am tired of not having a phone.
Thank you everyone,
Mark
Edit: this is what I did to root the phone:
1. download the toolkit
2. unlock bootloader (when fastbooting the phone said unlocked at the bottom, and a message about not being secure showed every time I rebooted the phone)
3. flashed twrp (no issues, still booted, recovery went to twrp. for some reason I had to flash multiple times as every now and then recovery would revert to stock op, although I did make a backup through twrp)
4. send supersu zip file to phone, install using twrp (phone would not boot, op logo stayed on phone for 2 hrs + until I rebooted to fastboot and tried to reinstall the backup I made, still nothing)
5. Try magisk (still stuck on op logo)
6. try to go back to stock, accidentally lock bootloader (now the phone is stuck in bootloop, don't know what to do from here as I cant get to fastboot and am unsure of recovery's accessibility.)
If you are sure you have a broken volume button, you need to replace it first in order to get the phone fix.
Correction:
Fastboot/bootloader = Power+Vol Up
Recovery = Power+Vol Down
This happened to me except I didn't even get anything appear on the screen -- the phone just periodically vibrated with the screen not even light up. I tried the reset toolkit which is meant to flash your phone back to normal using Qualcomm drivers or something, but that didn't work either. Eventually I had to send it to OnePlus who fixed it for free in under a week! They said the motherboard had failed.
I hope you get this fixed!
Thanks

thanks for the correction, I will keep trying the volume buttons, if it doesn't work by the end of today I will search for a new volume button.
Thanks again,

Damn, that sucks, and besides being unfixable (doubt it), this is my biggest fear. I'm in the US and really don't want to have to ship my phone to china to have it fixed. If you are in the US as well do you know if there is a OnePlus branch I can send it to in the US?
Thank you,

There seems to be one in Texas. Anyway, contact OnePlus and they may try to solve it over the air.
Apart from that, did you install the Qualcom drivers properly? Even with your faulty power button, try to hold it down for 40+ seconds (for the phone to switch off) and then immediately hold down the volume up button for 10 seconds and then plug in the phone to the PC. I know I am merely repeating the instructions of Naman Bhalla in his Mega Unbrick Guide but it is crucial to do them correctly especially the installation of the drivers. Try these steps repeatedly because for some people, the phone gets recognised after repeated attempts. Or else replace the power button and then try these steps.
I had to use the Guide last month and successfully resurrected my dead phone.

Can you boot into recovery by pressing power+volume down buttons?
Update: Got phone to show on computer as qualcomm under coms and ports
So last night I went ahead and held volume up for about 20 seconds, then plugged the phone in, keeping the volume up button pressed the entire time. my phone stopped bootlooping and showed up as a qualcom device! So I have downloaded the new driver the stock os, and am going to proceed to try to unbrick my phone.
Wish me luck,
Mark
Yes, I did, and its working so far

I still need to turn off the signed drivers features ( a huge bi*ch, I have to use another computer to contact microsoft or something to get my computer to load when I turn off safe boot or whatever its called), but once I do that I can install the driver and attempt to reinstall the stock os. Hopefully everything will go well.
Thank you,

So far recovery has not been loading, just the bootloop, but I have gotten the phone to power off by pressing the power button for 40 seconds, and the volume up button plus plugging in does make the phone register as qualcom 9008 or something like that. Basically everything is going well so far, and the faulty vol button seems to have been a software bug, as it does work when plugging it in. I will try to get to fast boot, but it did not work last time.
Thank you,
