Original Shield Tablet (WiFi) bricked or kill-switch engaged? - Shield Tablet Q&A, Help & Troubleshooting

When I got my replacement tablet for the recall, I followed the instructions to kill the kill switch on my old tablet (a 16gb Wifi only version). I deleted the TegraOTA folder, and used the zip file as well. I then installed BlissPop and have left it that way since.
A few days ago, I decided to switch from the now-defunct BlissPop over to LineageOS. For some reason, I couldn't get the tablet to boot into recovery (I installed the TWRP app, wouldn't boot into TWRP; I flashed TWRP using fastboot, wouldn't boot into TWRP; I flashed Nvidia's stock recovery, still wouldn't boot into recovery).
So I decided to flash stock, but new everything (I think the 5.2 or 5.3 version). Booted into OS setup (without connecting to network) so I could enable debugging/connect with ADB. This worked, so I rebooted into bootloader and finally got into TWRP. But, because of shared storage, I couldn't get into system folder to see if TegraOTA was back. So I decided to go back to original stock so I could access internal storage. Performed a factory reset, flashed the very original stock system/recovery/boot from these forums.
Restarted tablet and... nothing. Black screen. When its plugged in, the light shows it has charging, but no amount of time or effort pressing the power button will get it to do anything.
Did I brick it somehow? I've flashed various upgrades, OTAs, custom ROMs on both Shield Tablets I've had and am 99.99% sure that I didn't do anything wrong this time. Did I unknowingly flash something that would allow the kill switch to be thrown even if the tablet was never connected to my network? Is there any way to test? Basically I want to be certain its 100% done for before I toss it and buy a new tablet (I sold my replacement earlier this week, which is why I decided to upgrade the old one in the first place). Thanks in advance for any help!

If you installed latest stock and system detected tablet with bad battery it probably killed itself even if you did not connected it to internet

[Q] Help! I tried to root my tablet and now I seem to have broken it -- it won't boot

Alright, so yesterday I tried to root my tablet (Samsung Galaxy Tab 3 10.1 Wifi) yesterday by installing TWRP and then loading the Superuser zip found in their link in the play store. It worked fine--I had root access and all was going fairly well. I then tried to make a small tweak to the build.prop file by changing ro.build.version.codename from REL to L.
When I rebooted to apply that change, I could not start up, so I did a factory reset (not a big deal, no essential files on there). It then booted fine, but when I reinstalled/updated all my apps, the Google services were crashing like mad. So I reverted the build.prop file back to REL and again it would reboot, so I did another factory reset and all was good; the Google apps were fine.
Well I was still rooted and I wanted to take advantage of all that time I spent doing it, so I downloaded the bootanimation zip found on this thread and replaced my bootanimation.zip that was already on there. I restarted to see the animation, and this is when the real nightmare started happening. I could not boot now at all.
I did another factory reset, and still it wouldn't boot. I then used TWRP to do a full reset, and still nothing. I did an advanced reset and somehow managed to delete the operating system files (I have no idea how), causing TWRP to say that no operating system was installed. I still couldn't boot, of course.
Finally, I decided I had had enough of this rooting ****. I searched all over the internet looking for a North American version of my stock ROM, and finally found one posted on this forum post. I wouldn't normally trust any random file, but I was getting desperate here. I used Odin to flash that ROM, and there were no errors. Now when I go into recovery, it gives me stock and not TWRP, so I know that was probably successful.
However, I still cannot boot. I get stuck on the screen that says Samsung Galaxy Tab 3, which sometimes goes away and then comes back. I can't send it in for warranty, because it still says "custom" in the recovery mode. How can I fix this? any ideas?
I really want my tablet back :crying:

[Q] After disabling ATT, hell broke loose.

I have the shield tablet LTE version and after connecting to WIFI it immediately installed all OTAs upto the hotfix also. So here I am sitting with lollipop in my tablet and I decide to go for rooting and CWM installation.. After rooting using adb/fastboot and installing CWM image, I decide to disable ATTall access because I read that it stops the portable hotspot from working. So, did that and then process after process started crashing. First it started with background data not being enabled (playstore wouldn't open) , NVidia hub crashing, google text to speech crashing, etc.
So, I went to cwm and did factory reset. At the initial stages itself where it asks for language setup, the google text to speexh crashes and I cannot click next or proceed forward.
I flash the Lollipop OTA once again thinking it would overwrite the system but it didn't.. and the same issue keeps happening..
Now what do I do?

An update to the mess i was in...
I tried recovery mode at the fastloader boot menu and I got the robot lying down with a red exclamation mark sign. I pressed vol + key and it opened the original recovery I think. I wiped user data from this menu and rebooted. and now it has come to the original screen setup and so far no process crashes...
What could have caused this entire mess?
I am not sure what would cause your issues but i believe your best bet is to download the full rom image for your tablet and flash it via fastboot. That should get you back up and running. (Be warned doing this will erase everything on your tablet!! SD card will be untouched)
By fullmrom u mean the one from the nvidia developer website right?
Yes that is the one! I am currently at work so I cant post a link to it but if you need it ill try to post it once im off, in about 30-ish minutes. Good luck! (p.s. last resort is RMA)
Is your shield up and running once again? Just wanted to get an update. =]
Thanks javydawg, I didnt use the one on nvidias developer website as i simply did not have enough data left in my Internet plan .. its 2.3 gb in size... after recoVery i was left with lollipop so i flashed a 750 mb file tht i gt from these forums and updated it to the latest version.. i still haven't pinpointed the reason for my earlier trouble but will shout out if it happens again... have to be careful cos not sure if RMA is possible for me in India...

New to Nvidia Shield help !

Hello I bought an Nvidia Shield LTE and had Bliss Rom in it, I restored to the original (factory image) and everything seemed to go ok. after reboot I set the wifi and said that there was an update, it rebooted but after flashing the android bot with the progress bar everything went black. I have not been able to power it on or get into recovery mode, if I plug it to the pc it make a different plug in sound. but I have not been able to figure it out, please help.
Hi,
did you buy a "pyrotab" (a recalled tablet because of a Y01 battery) knowing what it was? Did the seller mentioned this?
Yours had Blissrom on it, the tablet could not download and execute the TegraOTA.zip executable that kills the tablet as soon as the replacement is activated. But since you restored the tablet using the official Nvidia Shield rom and did not flash the nomoreota zip file in TRWP *BEFORE* rebooting, the tablet downloaded the ST - YY kill update and your tablet is now a paper weight. And no there's no way to restore it, search the forums for confirmation.
I know this because I bought myself a pyrotab knowing what it was and read many times the instructions on how to prevent it to be killed. It had a crappy rom on it so I flashed the official one but made sure to run the nomoreota.zip and supersu in TRWP before rebooting to make sure it did not have the dreaded files and my tablet is still working perfect so far. (Gotta check that battery though!!)
Sorry for your loss!

Lenovo K4 Note (A7010). Won't power up. How to recover?

Ok so, I flashed a CM13 rom on a K4 Note (16GB internal and 3GB ram version). I pretty much followed all the steps required for flashing - unlocked bootloader - installed TWRP - wiped (factory reset) - flashed the Rom. Now, the phone booted up alright and worked for a day. The phone doesn't belong to me, and the owner decided that he wanted to factory reset it one more time. Since I also wamted to show him how TWRP functions, I booted into recovery via the advanced boot option in Cyanogen (Did not use the key combination). So this phone turns off and decides not to start. I waited for some time and decided to manually power it up. It won't. I held down the key for about 5 minutes and yet, to no avail. Not even a vibration. No response at all.
So, I would like to understand what happened with the phone, since as far as I can tell, TWRP was working fine. I used the key combo method to boot into TWRP thrice the night before - to flash CM, to flash gapps and to flash thr xposed installer. I can say CM was working fine since I used it for a night to get a hold of any bugs. Nothing went wrong at that time.
So, what can I do now? Since the phone is completely unresponsive and is not being detected upon being connected to the PC, I suppose it's hard bricked. But what cause the brick in the first place? Any possibe way to recover the phone? Is it even hard bricked though?
What about battery charging % frist chik battery I think battery fult

Nah, it doesn't charge either. I tried plugging it in and turning it on. It still won't.
It's just sitting there. Doing nothing.

Samsung Galaxy Tab 2 10.1 P5110 bootloop

Hi! So, my father's old Samsung Galaxy Tab 2 10.1 P5110 (bought 5 years ago) has gotten into a bootloop. It's an odd case. Basically, it's like the device is completely read-only.
To describe the symptoms:
It boots into the OS, but after 30 seconds or so it suddenly restarts. The device cannot be turned off (it just reboots and reboots and reboots...), so it empties the battery if left unplugged.
I can enter download mode and recovery mode, where the device is stable.
The device is not rooted.
I tried to flash it with TWRP recovery (it worked on my mother's tablet; exact same model, but no problem like this), but the recovery mode is always unchanged. I've flashed with Odin 1.8*, Odin 3.0*, and latest Heimdall; it always completes, but nothing changes. I've learned about having to boot to recovery after flashing due to a script replacing custom recovery, but even when I go directly to recovery mode, it's the same old stock recovery.
I decided to try another approach, by uninstalling apps during those short 30 second intervals of functioning OS; I got to uninstall one app (AVG anti-virus software), but after the reboot, the app was installed again.
I tried to go into recovery mode to do "wipe data/factory reset" and "wipe cache partition", but even that did nothing! Everything is where it was.
I can use ADB in recovery mode, so I tried to see if I could do some damage there, but the tablet is unrooted, and no rooting works either. (Tried rooting with Odin and "apply update from external storage" in stock recovery.) Couldn't find a writable directory to upload a su executable into either.
Just now I finished a 90 minute flashing of some Chilean stock firmware -- although I'm Swedish -- to see if that made things "rewritable", but guess what? All the old apps and files and settings were still there, in Swedish.
At this point I'm starting to suspect that I could hit it with a sledgehammer and it would just return to normal after a minute.
My father is not poor (just a bit cheap!), so buying a new tablet isn't a big deal, but I'm ostensibly a computer engineer...ing student, so it feels like a surrender to leave it unsolved. What might be the problem? Can memory in these devices become read-only due to some hardware fault?
Risky suggestions are welcome. If it's bricked, that's no problem.
EDIT: Whoops! My father ordered a new tablet; I was still going to experiment on the old one, maybe get it working again, but it seems that he went and tried the sledgehammer mode on it. But what happened is still an open question.
