[Solved] Hard bricked after pressing "Start" + "Vol. Down" (?) - Transformer TF300T Q&A, Help & Troubleshooting

Hi, I was trying to root my tab using Brk's Toolkit 8.0
But first, I had to go in APX mod. So I truned the pad off, pressed "Vol up" + "Start" but the tab just booted normally. I did it like 3 times and it always did the same thing.
So I figured I could test holding "Vol. Down" instead of "Vol. Up" while the tab was not booted but plugged to my PC.
The screen flashed, but the tablet didn't start. Instead, it turned black then showed the charging logo.
I tried again. Same flash. But this time the screen went black and nothing responds now. The screen is forever black.
How could this happen ? I know a device can turn into a brick after installing a ROM, but I didn't installed it yet...
Thanks for your insight
EDIT : Okay I feel super dumb but to be honest I didn't find this information elsewhere on the internet so I'm gonna share it :
After contacting Asus' support, they told me to maintain the POWER button for approx. 30 sec, then charging the device again.
Hope this could help someone

[Q] After System Restore - TF101 Keeps Booting Over and Over Again

Hello All!
My brother gave me his Asus Transformer TF101 to sell but it was heavily modified so I set about putting it back into factory state.
He had TWRP installed so I booted into that (recovery mode, volume down + power, etc.) and proceeded to do a restore. I selected the restore point and clicked "go." Everything seemed to work but now my TF never gets beyond the boot screen (the screen that says "ASUS, Inspiring Innovation..." and has the spinning circle). Obviously something went wrong with the restore and I can deal with that, however, I have a BIGGER PROBLEM now.
I cannot power down my TF. When I press and hold the power button it shuts down (the screen goes black) but then it starts right back up again. I have tried to hold the power button down for 3 seconds, 5 seconds, 10 seconds, 30 seconds, etc. but it always reboots.
Can someone please let me know how I can stop my TF from rebooting over and over again?
Thank you,
Jan
P.S. The main reason why I am needing to power down is I am trying to boot into APX mode so that I can use Easy Flasher.
try vol - and power more than 15secondes. Until you get 2 icons (1 for reset 1 for boot android)

Click to expand...
Click to collapse
When the tf turns itself off just start holding volume-up, eventually the screen will stay blank and you are in APX mode, I've had this issue a few times, just hold volume up and it will eventually boot into apx.
Also try volup and power to hard reset then it will turn on again automatically, be sure to keep holding volume up, apx will eventually come on.

[Completed] Sony Xperia Tablet S SGPT1211 not responding to reset/power comands

Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

Powered off, no charge light or power on

Hey all, I searched around, just haven't found the answer I'm looking for.
First, I did get it to bootup after holding Power+vol up/down, and I'm trying to understand what happened.
Running stock Verizon 4.4.2
Bootloader unlocked, S-off
Rooted
The phone was at about 75% charge and I was viewing gallery. I noticed that videos were no longer playing and was trying to get one up. The phone suddenly went black as if it powered off. I pushed the power button- nothing. Held the power button - nothing. Did that a couple more times for longer.
Then hooked it to charge - no light, nothing.
After a quick search I found a suggestion to hold power+vol up/down 1-2 minutes. I did that and it booted in about 15 seconds.
My question is, what happened? why?
Is there a way to avoid it?
And if it does it again what is the best way to get it restarted?
I still plan on flashing a newer ROM, just haven't done it yet.
Thanks
Really, no thoughts on this? Phone goes blank, won't restart. Someone on XDA must at least seen it.
Happened to me once but due to my own mistake.
I wanted to boot phone into bootloader, instead of shutting and then pressing vol down + power, i forced shut the phone by pressing power + vol up, here is where i commited the mistake, instead of holding the buttons for 7 secs( after which the phone should go off) i held them a bit longer mayb 15-20 sec, after tht i tried to boot into bootloader by pressing v up + power , nothing happened, did that several times, again nothing. Tried to power it on, nothing, connected to usb, again nothing.
It seemed like i had hard bricked the phone(thoughts of losing the phone came to my mind) but after trying and trying and trying again and again. It did got up(i held vol up + power for 7-10 sec, without releasing the power button, and releasing the vol up button, instantly held vol down button and it booted to bootloader).
Mayb the phone enters into some other kind of mode which only HTC is aware of.
Thanks piyushkohli97 for the reply.
Hasn't any developers run into this? Or someone with an understanding of the issue? It doesn't seem uncommon. I'm hoping to gain some insight into the issue. Anyone else?

Honor 8 boot loop - no fastboot no erecovery no dload - is it dead?

I think my phone has gone forever, but I'd like to check here if someone can save it.
I've been using this phone for 3 years, no changes besides OTA updates. Suddenly, screen froze and I held POWER button until it turned off. Then it rebooted and showed honor powered by android in blue background. It shows only that screen for a minute or so and then reboot again. If I hold POWER button, it'll reboot again (it won't turn off). The only combination of keys that produces different result is combo of VOL UP + VOL DOWN + POWER, which will turn screen black, then vibrate and then turn off (if I release keys before it vibrates, it'll start over).
I tried to put dload\UPDATE.APP in sdcard and nothing happened. I also tried all combinations described in a post I found in modaco forum (www[dot]modaco[dot]com/forums/topic/377629-honor-8-button-combinations-clarified/) and I don't get any other result besides what I described before.
Is there any way to fix it??
Did you try to press power and vol- ? When it boot, release power and keep your finger on vol- while connecting to a computer using USB. Normally, you should access to fastboot
EDIT: Oh sorry, in hurry I have not pay attention to the website you quote :'(

Samsung Galaxy S7 Will not power up, It showed a samsung logo and hung

My phone stopped working all of a sudden since last night, it was just sitting on the side idle and all of sudden it started showing a black samsung screen and hung and did not respond to any touch or anything else, At this point pressing powering button alone did not turn off the device, so I remembering pressing all of the button simultaneously and that turned off the phone but since then it wont turn on at all. I cant recall if the phone was on charge or not before it hung. But I am 100% battery was charged at least 70%.
After all that, I have tried all the possible combination of hard resetting this phone and still no luck to get it to power up.
Left the phone to charge overnight and in the morning tried restarting again with all the possible combination and still no luck to power up. I am clueless now.
Please let me know what could be the issue?
Any help would be appreciated
Update on the situation:
So Today I tried turning on the phone again and I pressed power+Volume Down+Home button and the phone started and it took me to the download mode. However when I pressed the up button it did not restart and stayed off, I pressed and held the same combition of buttons which are Power+Volume down+Home button then it took me to download mode again but I could not do much other than uploading a new firm to the phone which I did not want to do that. So I decided to restart it again by pressing the up button and it powered off and this time I went and pressed and held Power+Volume up+Home button and it did not do anything I tried this couple of times and still did not do anything. So I tried Power+Volume Down+ Home button and this time the device did not power up again.
At least now I know its not the hardware and some software glitch or a stuck loop.
Can someone please help me with this.
Thanks a lot Guys.
Update again:
Right after putting in the charging cable then the phone started up again and now the phone is showing an android blue screen "No Command" Pressing and holding Power+Up buttons do not bring it into the recovery mode? Please let me know thanks
