[Q] Desperate Cry for Help :(

Heya XDA - I have no idea WTF happened to my tab. Received notification of a OTA upgrade yesterday, taking me to one of the most recent 3.1 builds (.10 if I remember) - this morning woke up to another OTA update message offering me to go to .11 - accepted, downloaded, tablet hung up during the OTA process.
Now here's where it gets tricky. No matter what I do, when powering up my tablet I get the "Power Off - Shutting down" screen, and a endless spinning circle as the tablet claims to be shutting down. I cannot access any part of the system - all on screen commands are dead, except for the Settings icon in the lower right hand corner - i can click it, enter settings - but the moment I try to select a catagory or change any setting, the system goes right back to the "Power off - Shutting down" screen.
I am way outside the 30 days I can get a trade in - really don't want to have to mail this thing off to Acer.
Here's what I have tried:
One of Vache's full ROM images for my Region - flashed via power and vol process- fails about 1/4 of the way through.
Clearing cache/data - managed to get the vol/power+rotation lock combo going that clears cache and data. Still cannot boot - once I power on no matter what I do I get the "Power Off - Shutting Down" screen.
Tried to do the factory reset via USB keyboard + "Home"??? button? Heard mention this opens up a menu of some sort that I can factory reset from, I have two different USB keyboards and cannot manage to make this happen. Anyone able to explain this? Can this help me?
What's so weird about this - once I power up, I get the "Power Off - Shutting Down" screen no matter what I do. During this time, my battery shows up as %15 - this a500 has been on the charger for hours and hours, overnight last night, was 100% this morning before I applied the OTA update. Even with tablet plugged in, the battery shows as only 15%. What's even weirder - with tablet power off and plugged in, I do not get the red or blue charging light from the power button.
Totally freaking out here, no idea what to do. Anyone able to help?
Edit: When trying to manually flash a update.zip - I am getting the Clockwork Mod (I think?) flash screen - a green droid guy with gears turning. This fails about half way through. I have installed ClockWorkMod before this problem - but cannot enter the clockwork menu by the normal vol/power combo - I am so confused
Edit again: From browsing other posts - seems I am not the only one with this problem. The most recent OTA update failed, every single reboot since then is useless - all I can get is the "Shutting Down.." screen. Trying yet another update.zip via MicroSD to see if I can actually restore my tablet
Edit Yet once more (Problem Resolved!) - no idea how - but after a lot of searching I found a full package with build number 4.010.40_COM_GEN1 - this update.zip flashed with no problems, and my Iconcia is UNBRICKED! Sorry for the panic, everyone

OTA .13 Failure
I have the same problem, but got there by a different path. After many attempts to upgrade to .11 from .7, I downloaded the full file .02 to .11, decrypted and moved update.zip into the external sd card. Used the power / vol- combination and the update to version .11 went on without a hitch. Shortly after that, I received a notice that .13 OTA was available. It appeared to install without a hitch but after it rebooted (automatically) the tablet came back and immediately displayed the never ending Power Off screen described above. I would add that a two gears with a belt icon is sitting in the top left corner and "Android System" is noted beside that icon. I have tried every trick I have found in the forums to fix this:
1. Removed the SD card and shut down the tablet
2. Used power / vol- with portrait rotation lock turned on
3. Put the SD Card (with the .11 update.zip file ) back in and tried 1 and 2 again (no change: never ending power Off)
4. Tried power / vol+ with rotation lock. Saw the cach clear and looked very promising. Came back up with the rotating gears guy, but still went back to Power Off.
As soon as the power button is pressed the power icon goes red and stays there. Looks like the .13 update fools the device into thinking the battery is dean and it tries to shut down but never completes the cycle.

Exact same problem here. Downloading update.zip files like mad trying to find one that will work. Anyone have any idea what the hell is going on?

Moving to Q&A.
PS: Every Q? thread should be posted in Q&A.

Thanks for that - sorry for mispost. Again, as noted in my original post - question answered, issue resolved. Total panic this morning

For sure - sorry about the delay on that, was just so excited to be unbricked after a day of futile effort, I needed a break.
Anyway - here's what I have figured out. Somehow during the ota update I received this morning something failed - the tablet rebooted, and regardless of what I did the moment I booted up I would get the powering down notification. System access was not possible. This was on a 100% stock official 3.1 version - even unrooted before letting the update run.
Tried one of the full ROMS from Vache's thread in the dev section, as well as a bunch of other backup images I was able to find. Every single one failed at about 25%.
After a lot of fail - I gave this thread a try:
http://forum.xda-developers.com/showthread.php?t=1187578
"Bricked Tablet...help!"
I used the link on the bottom of page one - the unencrypted update.zip user kjy2010 was kind enough to upload - here is the direct link - http://www.multiupload.com/WCT2FYLMQC
This one worked - put on MicroSD card and flashed via vol/power method - result - 4.10.40_COM_GEN1 - and I am unbricked! Iconiaroot 1.3 worked for getting root after install - slowing getting my tab back to normal now

N910TUVS2EPK2 - got it rooted!

Happy, happy, happy! Since I got it to work, thought I'd share.
~ caveat emptor, not responsible if this doesn't work for you ~
First off, I followed this very helpful post from DeeXii:
https://forum.xda-developers.com/note-4-tmobile/general/recovery-n910t-t3-marshmallow-pe3-guide-t3406870
I had flashed the N910TUVS2EPK2 stock from Odin after screwing up my phone doing other crap. In any case, after doing that, I obviously wanted root again! Note that this wasn't immediate - I flashed to this a couple months ago, so have been fully setup with gmail, and other account settings. So, the above link gave the best overall, simple step-through, with handy download links. It worked, and even better didn't lose any of my settings. (but, no guarantees, make sure you've backed up!)
Additional details that would be helpful:
- make sure you run Odin as Administrator.
- Odin: click the button next to AP, and then go select the twrp archive you downloaded
- Power off phone, hold boot into download mode (power, home, volume down at same time). click volume up when it says so.
- connect to Odin. you need to see the square just below ID:COM turn blue.
- Click Start to flash the twrp.
- IMPORTANT: after it flashes, the phone will auto-restart. *Quickly* pull out battery before it boots, otherwise it will put back stock recovery on you. (this happened to me - I had waited until it had fully booted, then powered down, then brought it up in recovery mode, and it wasn't twrp! - so remember, pull out battery right after it cycles after flashing)
- Put battery back in, and then boot into recovery by holding power-home-volume up simultaneously. If you end up seeing the nice pretty twrp squares, then this worked. It is interesting that there is also a message here stating that the kernel may very well write back the custom recovery. So, can't say if this will be permanent or not, but at least you can now flash the supersu. (subsequent reboot into recovery still seems to have twrp, so groovy!)
- (presuming you had already put the supersu on the sd card or internal memory - I used the systemless supersu), click install, select it and flash.
- just for kicks (not sure if this was needed or not), after flashing I saw an option to wipe cache/dalchik, so I did that too.
- rebooted (it took awhile, had to 'optimize' all the apps, etc.) - and I'm rooted!
If anyone has been trouble with specifically the N910TUVS2EPK2 build, then I hope this helps.

Thanks man, had the same issue. I figured it might be something to do with booting int OS. Sure enough with 6.0.1 EPK2 rom you MUST load into boot recovery right after flashing TWRP as you stated.
Something went wrong with my OTA update of EPK2 and it started to bootloop( 2 vibrates upon restart and then random amount of bootloops, and then random, soon-coming freeze upon loading in OS and continuing boot-looping) sometime after the update. I erased most of the old stuff via TWRP reinstalled EPK2 bootloader separately and then flashed EPK2 rom and it seems to be OK so far (knock on wood). We'll see hopefully it's not hardware issues like many people were reporting with bootlooping.

Can't you just uncheck the Odin option to reboot instead of the frantic battery pull?
Just wondering, as I'm going to do this later- thanks!
Steven.RN
Followup: Yep. Slip over to the options tab in Odin and uncheck "auto reboot". After Odin flashes TWRP, (the bar is all the way across the download screen, and the Odin Log says "succcess") go ahead, disconnect the phone from USB. Do your battery pull, replace battery. Close up the phone, then hit Volume up, home, and power at the same time- Bang! TWRP screen.
Further note: first time I did this flash, it didn't work, it just stopped in it's tracks. Then I realized I had to enable "developer mode" by clicking on the build number in the "About phone" sections in settings 5 times, going into Developer mode (the new option will present itself in the menu on settings), then: enable OEM unlock and USB debugging. Odin will flash TWRP just fine after that. (Duh on me!)

Trying to go back to stock firmware. Need help

I was messing around trying to root my phone. Now its stuck in the ODIN mode. Which is the necessary ODIN and stock firmware to flash it? Do all I need to do is load into ODIN using volume down home and power. And in ODIN, click AP and choose the tar file, and then start? Can someone link me the proper ODIN and AP file please? My phone is a brick. Im a retard noob. : ( lol. Im trying though. Any help is appreciated.

It says "An error has occured while updating the device software. Use the emergency recovery function in the Smart Switch PC software.

Using Samsung Switch
All hope is not lost. You may have done what I just did and tried to flash a root exploit inappropriate to you phone's firmware version. At this time, the latest factory firmware that you can revert to is rev02 (files with the string "G935TUVU4BQB1" in their name). If you're on the latest T-Mobile update, the you've got factory rev03 firmware, for which no online release is available. Basically, T-Mo users can't restore if we try to root and screw up. But don't panic yet. Hopefully you have a computer to install Samsung Switch on.
1) Download and install Switch, and start it up with your phone unplugged. When it shows the animation of connecting your phone, do so. It probably will list it as an unrecognised device, ignore that.
2)Next to the minimise button in the upper right, select "more", then "Emergency software recovery and initialization". Go to the second tab in the window that pops up, labeled "Device initialization". If you've got the T-Mobile version of the S7 Edge, your model number is SM-G935T (which I'm assuming since we're in the T-Mo subforum). If it rejects the model number, ensure that your internet connection is working; I experienced network issues at the same time and drove myself nuts for a few minutes.
3) It then asks for your device serial number. If you know that, great. Otherwise, unplug your device. Perform a safe reboot by holding Home+Volume Up+Power, and release when a blue screen comes up informing you that loading custom OSes is dangerous. At this point, push the Home key (which the phone should say leads to barcode). The barcode screen will have your serial number on it, write it down. Safe boot the phone again (Home+Volume Up+Power), but this time press Volume Up to get back to download mode. Go back to Switch, which reset itself when you power-cycled the device, go back to that "more" menu, to the second tab. Input your model again, followed by the serial you just wrote down.
4) At this point, Switch should start downloading a pretty big file. If it's anything like the size of the other factory firmwares I tried downloading (the rev02 ones that won't work, with the G935TUVU4BQB1 in the names), then it should be around 2GB. Wait for that to finish, and it'll start pushing it to the phone automatically. Afterward, your phone has been factory reset, and will ask you to sign in with a Google account that has been previously linked to it. This will most likely be the one you were using before you tried to root. From there, it's like doing the first time setup of a new phone.
Sorry my recommendation is a month late for you, I only just had the same problem tonight. We should have been on the same firmware version, though, so if you're still looking for a solution, then give this a go. Hopefully it also helps people who get stuck in a similar conundrum. Good luck!

Simply Odin stock and start over make sure partition is uncheckeded

do you have a option if the smart switch is not recognizing at all?

Bricked S8s after software update.

Hi. Browsed for ages and always come here for answers.
Here's my problem.
2x S8s. SM-950f.
Updated to most recent software through software update. Both phones were glitchy and crashing and just generally irritating after.
Factory data reset etc. This did not resolve the problems, also led to one of them having issues with FRP (annoying)
Used Odin to try and flash the latest firmware (from sammobile, UK BTU) after flashing both, they reset and powered on. Got stuck at the S8 screen.
Restarted then both were at the "an error occurred during update" screen.
Managed to get back to download screen. Re checked the software and model numbers, even that the bootloader was the correct version etc. All was fine.
Connected to Odin, shows that it is connected, but nothing happens when clicking start.
Now after attempting that, both phones will not power on.
(One will when placed on the wireless charger, but just sticks at S8 screen) and download mode or reset screen can not be accessed. So, not exactly happy. And totally out of ideas
Any suggestions, beyond taking it to a shop to see if anyone can help.

yes .....dont tuch the phones for 24 hours let the battery die ...it will...connect to pc and then try download mode....u may need to press combination for like 1 minute to get to download mode....flash twrp reboot directly into it when odin says successfully .....wipe system data ....dont turn on phone download any custom rom flash and enjoy.....it will trip knox but worth than getting a new board....

Okay, will give that a try.
TWRP?

TWRP install
https://dl.twrp.me/dreamlte/twrp-3.2.3-0-dreamlte.img.tar.html: Download link for twrp SM-G950F (dreamlte)
Just said, wait until your device powers off due battery insufficience. Plug cable and hold at the same moment vol(down)+bixby+power. Then press vol(up) at the warning screen to proceed to odin mode. Let it charging a while like 1 h. Then unplug it and plug it to your pc. In Odin select ap the previous downloaded file. Take your mobile in your hand. With one hand, prepare your fingers to vol(up)+bixby and with the other hand start the flashibg process. Be careful, and take your hand directly from the mouse if you clicked start in odin, and position your one finger to power button, but dont click. If odin start pass, press immidiately the buttons (vol(up)+bixby+power) and let it to start into recovery. If you arrived to recovery, reply to us if not search for help!!!
Good luck

i have the same issue with my s8 but when i boot in download mode the screen goes black but if i press volupe up it connect to odin with black screen you shoud give it a try

Will try that

Okay, downloaded TWRP, can get phone calls nected to Odin but when I extract TWRP it doesn't give a valid file type.
Am I being dumb.
No files appear that Odin will recognise.
Also just shows as "recovery" no .tar or anything

Ignore above. Corrupted download.
Sorted.
Now when flashing TWRP is gets to a fail due to
"Complete (write) fail

Not sure what stage your at and maybe some more useless ideas
1. Trying to flash twrp is kinda of useless if you can't get into your system need oem unlock for that.
2. Have you tried taking out Sim card and SD card and reboot.
3. If you can at least boot try smart switch as it has a emergency recovery option.
4. Trying rebooting in safe mode.

All been attempted

930V stuck in bootloop after OTA

Hello All, So I have a friend's 930V here. She let the phone "try" install the latest verizon OTA a few days ago, best I can tell 8CRK1 (I know). It did not complete. I have been attempting to fix it for a few days now. I have only been able to get the phone to actually boot into recovery twice. All other attempts say either "erasing, then installing update" or just "installing update", neither of which ever complete. The phone then reboots, says "recovery booting" and does it again. But I can not get it to boot into recovery to wipe the cache.
I have flashed it several times using odin (v3.13.1 and v3.13.1_3B) with firmware (8CRK1, 8CRJ3 and Umodel 8CRJ2). They all complete and pass in odin, yet it will not boot.
Some it will not even turn on, so let it sit for a while, when I come back it will turn on
- Will ticking erase NAND and/or REPARTITION help?
- Should I force the PIT file (HEROQLTE_USA_VZW)?
I have even gone to trying the Verizon/Samsung software upgrade utility, which fails half way through and says phone disconnected (on the phone it says unsupported dev_type)
-I'm about to rip my hair out- Any advice would be awesome!
thanks
A-
the screen grab I've attached are from the 1 of the 2 times it actually got it into recovery
