My Samsung Galaxy S3 won't turn on! - Android Q&A, Help & Troubleshooting

Hi! I'm new here, so sorry if I posted this in the wrong thread or I formatted it incorrectly.
Recently, I rooted my Samsung Galaxy S3 using Kingo Root, with the intention of installing Ubuntu Phone.
Rooting went well. I ran the setup, and the rooting process completed successfully.
Afterward, I attemped to unlock my bootloader (in order to make a nandroid backup), using EZ Unlock.
After the process finished, I "restarted" my phone by holding the power button and tapping "restart".
The phone turned off, and it's stayed off. I thought I had accidentally tapped "Shut down", so I held the power button, expecting to feel the standard vibration that the S3 usually produces when it turns on.
Nothing.
I am completely unable to interact with the phone. Holding the power button does nothing, meaning I can't boot into normal, recovery, or download mode.
I've tried removing the battery and all that, but nothing has worked at all so far.
Does anyone know what I should do?
Thanks!

[Q] Problems while rooting. How to restore?

Hello all.
Today, I tried to root my TELUS Samsung Galaxy S Fascinate by using Odin and CWM3-Voodoo-blue.tar.md5. I received a "FAIL!" message, so I pressed Start again, which yielded nothing. So, I removed the USB cord from the phone and tried to boot it up. Nothing happened. I tried to use cwm-recovery-ALL.tar, but, again, I received a "FAIL!" message, and ended up with nothing.
It seems, at the moment, the phone can boot up in download mode (Vol Up + Vol Down + Power). However, the screen appears filled with randomly coloured pixels, and nothing else works on the phone. Is there a way to recover my phone from this state?
I'm going to sleep right now, so I won't be able to reply right away, but I'll check replies as soon as possible.
EDIT: Now, it seems as if the screen isn't booting up at all. However, I can still see the download screen with Vol Up+Vol Down. I don't think the phone was rooted at all, so I'm thinking of sending it back to Samsung so they can fix it. Is there a way to check if a phone is fully rooted or not?

[Q] Asus Padfone 2 does not turn on - Any way I can root the phone?

Hello guys,
A week ago my asus padfone 2 for some reason it has stopped working. Every time I press the power button it turns on; it shows the welcome
screen (the ASUS logo) and it stays there for like 10 mins. After that it comes up with a black screen and some chinese. I asked a friend from China and he told me it says something about reset the phone. So i pressed the ''reset'' button but nothing happened. I tried to reset the phone by pressing the volume and power button, i chose wipe factory data option, the process was completed and when I rebooted the phone it was doing the same thing (showing the welcome screen and stays there until it shows the screen with chinese instructions for reset).
So basically I can not turn on my phone. Is there anyway I can root the phone by not turning it on at all? I tried to follow a tutorial in which you need to install superboot rooting package... but when I click on the install-superboot-windows.bat file it just says that it's waiting for a device. I guess my laptop can't recognize the phone.
Any help would be much appreciated,
Thank you

Power button

Ok, i've searched all over the internet for the same problem and i couldnĀ“t find anyone who've experienced this.
Where's what happened, my power button started to mal-function after my phone restarted. Now i cant lock or unlock the screen with it. The funny thing is that if I press it long enough it shows that [Shutdown/restart] menu. And if i keep pressing it it will soft reset the phone as usual.
I've already tried an app to se wich keys are being pressed to rule out the stuck key problem. The phone no longer recognizes the quick press of the key to lock/unlock, it only recognizes the long press of the power button.
Also today it refused to identify the charger and didn't charge at all, dunno if it as something to do with it.
My phone is the Wiko Wax, rooted, custom rom( Tesla 0.4.9a) android 4.4.4, with custom kernel as well.
I have already re-flashed everything, formated my phone and everything, but it doesn't seem to get fixed.
This started to happen after the phone restarted it self, without me doing anything to it

Jiayu G4 (God I hate to title it like this, but yes) stuck in bootloop

How the problem occurred
So a year or two ago I bought a Jiayu G4A/T/Whatever they're calling it and safely got it here. I've used the stock ROM for a bit but I wanted to get rid of the bloatware that was still on it, so I eventually ended up with a properly rooted phone with a ROM from Jiayu.es (Everything worked, have ClockworkMod as recovery, accessible via Mobileuncle Tools), which was essentially a stock Kitkat rom made to work for the phone. Now I got sick of the ROM and recently saw the new EMUI version on Huawei's P8 Lite, so I figured I'd look around for a tailored ROM running that, and ended up at "jiayu-emui-3-0-stable" from Needrom.
What I did
1. I downloaded a ROM from Needrom with identifier "jiayu-emui-3-0-stable" (I can't post external links)
2. Backed up my important files following a guide from androidcentral titled "[Guide] How to Backup and Restore Apps and Data when installing new ROMs" that I can't link,and did a full backup using CWM
3. Placed the ZIP on my internal SD card, went into recovery, wiped data/cache (not dalvik, since it wasn't described in the instructions, I think this might be a probable cause) and installed the new ROM from ZIP
4. Rebooted the phone and now it's stuck in the boot loop I mentioned.
What the problem is
Bootloops aren't that much of a problem usually, except this one is... I can't get into recovery mode. From there on it'd be cake, since I made the right preparations, but I can't get into it. While connected to my PC it keeps powering on, showing a splash screen from Jiayu.es briefly (which shouldn't be present anymore) and powering off after 10 seconds, only to come back to the splash screen.
What I've tried
I've unplugged it, removed the battery, waited to get a full power cycle and tried to hold my buttons in these combinations: [power button + volume up], [power button + volume down] - but neither work. It just keeps going with the boot loop. I can succesfully power it down, and when I plug it in from there it shows the low battery image. At the moment of seeing that I thought I could connect to it using ADB / Fastboot, but no luck there either. It keeps saying no devices found, and with fastboot it keeps on <waiting for device>.
My questions
What exactly can I do if there is no way for me to get into recovery mode? Are there any alternatives? How can I get my device to be recognized by ADB? Is that even possible? Why is this bootloop any different from others?
Update from the massive Q&A thread:
ZipAddict said:
Is it booting up on its own too after being off? This happened to wifes phone and it turned out the power button was stuck. I took a pencil and hit the power button with the eraser a few times and it worked then. Her case mustve dislogded it. I will keep my fingers crossed for u. If not send me a private message and i will look for an answer tomorrow and get back with u

Thank you for the reply!
Yes, it does. I took the battery out and let it lay disassembled for a night, after which I cleaned it a little and re-inserted the battery. With the case back on, nothing happened, so the power button wasn't stuck for sure. When I powered it back on with the power button (no USB attached) it showed the emblem for ~8 seconds and powered off. It then buzzes to show it's powered on again and up comes the splash screen again. Could it be that the ROM was just a rebooting falsehood? Why would it disallow me getting into recovery mode? I really hope there is something that can still force the device into recovery mode / interact with it somehow while in this state.
Oh, I also tried to see if the volume down button was broken but all the contacts seem intact, plus, they worked an hour before I started switching roms.

Samsung S+ only boots to 'Download Mode' - Any guidance?

Hello,
New to the forum and all of this, so please go easy on me.
I have a Samsung Galaxy S9+ (SM-G960F).
On Thursday evening, I went to the device and it was completely dead. It wouldn't turn on and I attempted to do power key/volume down and various other button combinations I found online that would normally boot the device. Obviously, I attempted to charge the phone, but the charging light did not come on yet the phone did warm up slightly as if it was charging. After leaving it plugged in for so long, a 'Downloading... Do Not Turn Target Off' screen appeared. It also states I can restart the phone by holding volume down/power button for seven seconds. However, when I do this the phone just goes dead and doesn't boot up. After plugging in the charger again trying various buttons, I eventually end up back at the same download screen.
I've read about recovery mode, safe mode etc but I am unable to access them using the instructions I've read.
Any help would be appreciated. Ideally I'd like to be able to access my photos/videos/messages on the device and be able to use it again.
