Galaxy tab A 2016 (SM-T585) backlight not working after security update - General Questions and Answers

I just downloaded and installed newest security update (2018-06-**) for my device. After restart screen just went black. When i plug in to charge it, it vibrates, so it is working. Tried force restarting with Power + VolDown, it restarts, but you can only barely make out even the samsung logo when restarting because the backlight does not light up. I tried going into system recovery mode but i just can't see anything... What should i do now?

Find screenshots of stock recovery from devices just like yours, then use that screenshot as a guide when you boot into recovery, look at the screenshot and look at the list of options in stock recovery. You're looking for the "wipe cache partition" option. Starting from the top of the list, count down the list until you get to the factory reset option. Now boot to stock recovery, then press the volume down button the same number of times as what you counted from the screenshot. For example, in the screenshot, if "wipe cache partition" is the third option on the list, just press the volume down button three times, this should put you on the wipe cache partition option, then press power, it should do the wipe. Then try rebooting.
If that doesn't help, use the screenshot again as a guide to use the "factory reset" option" by counting down the list then pressing volume down that many times then press power to do the reset then reboot.
If that doesn't work, you'll have to flash your stock firmware via PC.

[Q] Restoring phone to factory settings using ODIN

I flashed a rom using the guidance of the Samsung Galaxy S3 toolkit. Everything went well--until the rom--which is the Ilusion v2.0 [4.2.2], (found in the Sprint Galaxy S3 Android Development section)--got stuck in an endless animation right hefore the phone fully restarted to the home screen.
It's just stuck in this endless animation, like it's perpetually loading.
It's very frustrating. I want to restore the entire thing to its factory setting. Is there anyway to do this using Odin? Maybe when the phone is in Odin Mode?

First before you return to stock I would recommend fully powering the device off and then booting into recovery mode by holding the power button + home button + volume up button until you feel a vibration and see some small blue text in the upper left hand corner of your phone's screen, then continue holding the home button + volume up button until you enter recovery mode. Once in recovery mode select the option's to wipe cache, wipe dalvik cache, and perform a factory reset. After you have done those three things select the "reboot system now" option and the phone should then reboot and power on normally and enter into Android no longer getting stuck on the boot animation. If you do however want to return to complete stock you use Odin to flash the stock firmware for your phone which can be downloaded from here I would reccomend checking outthis video on how to re-flash the stock firmware for the Sprint Galaxy S3.

[Q] Nexus 5 No Command Stock Recovery

Hi!
I have recently purchased a Nexus 5. On the day of the purchase, I received an OTA update for camera issues (it currently says build KOT49H). However, although I belive this install went through, as it changed Android version from 4.4 to 4.4.2, it didn't work as expected during installation. It froze during the Android robot screen, while it was installing. Bottom-line, now that I enter recovery, the first thing I see is a dead Android with a red triangle on it and the message "no command" underneath. If I press any button, the menu appears and I can choose the options. However, sometimes if I press volume up, instead of going up the menu, it closes it and shows the dead android background image only. I press again, and see the menu again, but can't go up, only down.
The phone is stock rom, not rooted, not altered in any way! I have attached several pictures in this respect.
Any clue about this issue?
Thanks!
If you reboot your system from recovery, you are stuck on "no command" screen as well?
Try wiping cache partition and rebooting. if it doesn't help, then do a factory reset and see if it helps.

No, the phone actually works if I reboot it normally. Only when I enter recovery I see this dead android robot. When I initially saw this dead android after update, I did to a wipe cache from recovery, as well as factory reset both from phone, as well as from recovery. Still the dead android in recovery remains, as wallpaper image...

That's the stock recovery and this is the way it should be. It's perfectly normal.

Thanks, I guess you're right! It's deceiving, however, that Google chose this image as default for recovery! I thought something went wrong...
However, I have reasons to believe that something is not right! When I enter recovery, I see the dead android, which is perfectly normal. In order to see the options (reboot, wipe cache, factory reset etc), I have to press volume up. If I press volume down, I go down the menu. If I press volume up, I should go up the menu. However, this leads to disappearing of the menu and back to the dead android background. If I press vol up, I see the menu again, with the cursor on the last position... I can't go up the menu. Is this normal behavior?
For instance, I had to select "wipe cache" and only after this process ended, by pressing vol up I was able to move through the options and choose reboot. Vol up in this case wasn't making the menu to disappear.
Thanks!

[Q] Nexus 5 stuck on boot animation after a wipe all data/factory reset....

Hello,
I had an issue of my Nexus 5 restarting whenever I tried to unlock the screen. Since, I have searched several websites and found that I need to do a factory reset to fix the issue. And, I followed the below steps:
1.If your phone is on, power it off.
2.Press & hold Volume Down and Volume Up, and then press & hold Power simultaneously until the device turns on. You will see the word Start with an arrow drawn around it.
3.Press Volume Down twice to designate Recovery mode.
4.Press Power to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.
5.While holding down Power, press Volume Up.
6.Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it.
7.Scroll down to "Yes - erase all user data" and press Power to select it.
When everything is completed. I tried restarting the phone by clicking the power button, and what I see is the Boot Animation . Waited for an hour, two , three and five. Still i see the same. Please help me. I tried to search for similar posts with no luck.
Thanks in advance.

Stock recovery wipes everything AFAIK so your user data and the OS are gone... You have to flash the stock build (factory images) or take the opportunity to flash a new recovery and a custom rom.
EDIT: maybe not I actually never used it.

It doesn't touch /system or /boot. Only /data, but not excluding /data/media like custom recovery would

Oh yes I remembered there was a difference regarding the wipe process. Thanks for the clarification.

Did factory reset now bricked

So I did a factory reset, the tab rebooted to wipe the device, went to nvidia logo then screen went black, shuts off automatically and I can turn back on just for it to get right past the logo and shut off again, I've tried volume up with power and volume down and same thing happens. Sometimes the power won't even turn it back on for 5-10 minutes. Any suggestions?

Dumb question, but are you sure the battery is charged? I would leave it plugged in for awhile and try again. Then if it still is not booting try to enter download mode while connected to PC. Mine did something similar to this once when I did a factory reset as well. It only recovered after connecting USB to my PC.
I'm guessing you have custom recovery installed?
1. Download the factory image from NVIDIA website (specific to your device version),
2. Go into fastboot by pressing volume down and give a slight nudge to the power button (don't press until the logo comes up, just a quick nudge will do)
3. Unlock your bootloader using the instruction which can be found on this forum (if you have, skip this step) sorry I'm on mobile phone, so a bit hard to do a search for the link with small screen.
4. Unzip the recovery image zip file.
4. While still in fastboot, flash the recovery images using flash-all.bat contained in the unzipped folder.
You will lose your custom recovery and your root, but since you were gonna wipe your device anyway.. let me know if you're stuck somewhere.
I think i might have found fix....
Shut down the device with long press (8sec) Power button
Press and hold Vol down key
Press and release Power key
Device enters fastboot mode
Select Recovery mode option (using Vol up/down for navigation and power key to select)
Device enters recovery mode (after showing NVIDIA boot logo) with Android Robot screen.
Press and release Vol UP + Power button simultaneously
Then select wipe data/factory reset with Vol up/down key to navigate and power key to select
try this but be PATIENT AND wait for it to say erasing then i think ill be normal once its done also just wait with it on the "blank screen" we could have just got ahed of are selves and whent to conclusions and thought it was bricked

1) Turn off the phone completely by holding down the power button
2) Hold the volume down button and power button at the same time and boot up your phone in fastboot mode
3) Use the power buttons to navigate to recovery mode
4) You'll see a dead android with a message saying no command
5) While holding the Power button, press and release the Volume Up button once.
6) Press the Volume Down button twice to highlight "wipe data/factory reset" and press the Power button to select it.
7) Press the Volume Down button seven times to highlight "Yes - erase all user data" and press the Power button to select it.
After the reset is complete, select the option to reboot your device.
