no, because there is still no update for my device, my tablet wont go to safe mode now(maybe because i have done several flashing in my device & it often fails) , i have tried downloading apps that will automatically put your device to safe mode after reboot but it will say "unfortunately *** stopped" then reboot again to normal. But i will try reinstall my rom after im done with my work, is there any other options?

Turn On Safe Mode
If the device is on, turn it off.
Press and hold the “Volumem Down” button, Then press the “Power” button until the Galaxy Tab powers on.
Continue to hold down only the “Volume Down” button until the Home screen loads.
............................................
Maybe some of Apps cause the problem try to uninstall new them
I had the same problem with Galaxy Grand2 after update but after switch to safe mode the problem solved
After all if the problem is still exist install new rom with Odin [Download the Rom from http://samsung-updates.com/device/?id=SM-T231 ]

[Q] Help Nexus S Totally Bricked!

Please help if you can, would really appreciate, dont know how to unbick my totally F$$$$### Nexus S Phone.
Even in recovery/fastboot mode on my Nexus S (Vol up+power), I cannot get my system to recognize the device....in fact, even in Windows, I am not able to get the system to recognize my device in Recovery mode/Fastboot mode....the only way it will recognize the device is if it is turned on the normal way, and hangs on the "Google unlocked icon" screen.
Some background info:
My power button recently stopped working...I thought it had to do with the fact that I updated NexusTools (was running a CyberGR rom...cant remember the name...had V4 Ultimate in it (downloaded from Rom Manager)).
So what I did was download/install (from the same developer) their hybrid ics rom....that did not brick it...but it also did not fix the power button...so after not liking the new rom, and the fact that it didnt fix my power button, I reflashed to the original rom I had installed (wiped everything, including doing a factory reset), and it just hung on "Google unlocked icon"
Now my phone does the following:
- First of all, the only way to power the device up is to plug it in (it automatically turns on and tries to boot without me pressing the non-functional power button)
- If I let it try to boot, it infinity hangs on the Google unlocked icon screen
- If I boot into recovery (by holding vol up button and plugging the phone into a power source), it hangs on the recovery screen...meaning the power button, as well as the volume buttons, as well as any buttons are non responsive.
- If I boot into recovery, the device doesnt even register on my system....
What am I doing wrong? What can I do to try and fix this?
I would truly appreciate if anyone reading this has some insights for me.
THANKS!!

yes, sounds like a dead power button(i have one myself).
try going back into your recovery, do a full data wipe(factory reset), then reflash the rom(and gapps). if still nothing, redownload the rom and try again. in your recovery, there is an usb option. use it to transfer your newly downloaded rom from your computer to phone.
Once I am in recovery mode it "freezes" though...as in not even the volume buttons work...they worked fine before, and even work to get into recovery mode...but once there they no longer work...nor does connecting the device in recovery mode to my laptop....so im kind of at a loss, as I cant even use Fastboot/adb to wipe/push anything on the Nexus S through my laptop

im guessing that your using cwm recovery?
give your phone a few smacks on the back near the power button, your phone thinks its being pressed in.
yes, it definitely thinks it is being pressed in...thats for sure...and makes sense...ill try that haha!
Yes latest CWM Recovery...5.0.2 or something like that...just updated that before phone died...
Weird...so i "smacked" the phone a bit...when I do it in recovery mode, it reboots the phone into recovery....so it definitely thinks its being pressed down constantly...but I have found no way to make it "un-pressed"...only briefly by smacking it...

in twrp recovery, theres an option to not use the power button to select(thats what im using), is there a similar option in the newer cwm recovery? tr\y pressing the soft buttons). also, see if sticking a fingernail in between the power button helps, to pull out the button a bit.
After continuingto smack it...as well as "pulling" on the power button, I am not able to use volume buttons and power buttons within recovery...flashing a new rom now...will let you know if that fixes it...otherwise I will try unbickable in ubuntu again and see if that fixes it thanks for the pro-tip of smacking it, haha!

Try thisDo it for your own risk )
Remove the battery and insert the battery again, press and hold the volume up and down,
press the power button and wait until the screen (SAMSUNG) appears then release the power button but keep the volume up and down until recovery appear,
then select (backup / restore) and restore backup if any, otherwise select factory reset and reboot (but remember this process delete all personal data.)
Hope that helps!

Power button Failure, Can't go into Recovery, Download.

My power button decides to become unresponsive.
So I tried to unroot my phone and bring it back to a stock image and when I go into download mode, 2 seconds later, it turns off. :crying:
I try another method by using mobile odin to see if that helps. Tried to flash the stock image and it tried to reboot to Recovery mode. Nothing. It stays in a black screen after the samsung galaxy s3 logo. After pulling the battery, it tries to reboot to recovery again and still, a black screen. The only way to stop it from booting to recovery is to set it back to download mode. I hold the power button and it restarts. ( The power button seems to work when I try to go to recovery, download, power on.
I am running Cleanrom 6.0 R2.
I am in deep [email protected]#!. I do not want to go to verizon and notice my phone is rooted and I can't fix it without a huge bill.
Please help if possible

S6 Blue Light permanent Bootloop

Hey,
I just flashed Xposed for 6.0.1 but forgot Samsung need different Files now I stuck in Bootloop (Samsung Logo)
Is there anyway to Turn the Phone off so I can go to recovery? Currently it just keeps flashing, hold power Button not working =/
So I guess I need get the Power drained? Or is there some "Trick" to shut it down? Reboot working with Vol - + Power but no shutdown.
hold home button volume up and down button then hold power button soon as you see screen go off let go
Worked Thanks after uninstall I stucked on the Main Screen, so I flashed a Original FW with Odin hope this Helps.
Is there some Xposed for Samsung SDK 24? I couldn't find.
A piece of advice, you can also insert your charger. When you force a reboot it will shut down and display the charging animation. Your device is still off. From there you can boot into recovery or download. Worked here after a messed up odin flash

(help) Bootloop after OTA update

Hello
My stock A515F/DS received an OTA about 3 days ago. After it restarted to finish the update, it got stuck in the boot logo. It will reboot on itself from time to time, and I was able to reboot it manually by pressing vol down + power, but I can't get into recovery or donwload mode (by pressing vol up as soon as it reboots). The screen flickers for a moment, but it reboots again. We are under quarantine by federal law so I can't get my phone to samsung. Is there any way you guys know to flash it without going into recovery/download mode? I don't mind losing my data, everything is on my drive account, I just want my phone again
Thanks in advance
I think there is no way without entering in download mode or bootloader. Try with this:
When the phone is on, no matter which state, press Vol down + power until it reboots. As soon as the screen goes black, change to Vol. up+power. If this is successful, you can then select Reboot to bootloader to enter in download mode.
If this doesn't work, the next solution is waiting the end of quarantine
