[!] SGS3 Screen off, boots up, no recov

The TL;DR is - Running ROM fine. Phone boots up but screen does not turn on. Does not seem to boot into recovery/download mode. adb is attached aka works.
Phone was sitting on desk, untouched and not charging. Now the phone screen does not come on, but hardware keys light up and notifications come on. I then charged the phone for several hours. Hard reset with a battery pull, let it sit for 10 mins, try to reboot. The phone vibrates once, and 30 seconds later notifications come in, hardware lights come on, and led blinks. So the phone is booting fully, but no screen on.
If I try either of the recovery or download combinations, the same normal boot up happens. So I cannot seem to get into recov/download normally. Odin does not recognize the phone. Windows OS recognizes the internal and external storage as normal. "adb devices" returns nothing.
Is there anything you think may solve my screen-off predicament? .... Worst case its a hardware problem Other than that, I am friggin stuck here. Your assistance and suggestions are greatly appreciated!

Had a similar issue when a flashing went bad. My charger was plugged in and for some reason it just kept looping like you mentioned. No combination worked.
I disconnected charger and pulled battery. Waited a few seconds and did the recovery combination. That did the trick. Hope it helps

I am open to suggestions. Plan on opening and operating, as I suspect it's a hardware issue. Worst case, any have experience with replacements?
(Oye, now I'm reviving the OG Droid Incredible ...)

Take it into a pitch black room and look closely, does the backlight try to turn on? I had a very similar problem where my backlight just died, I could see the faint outline of my home screen (like my brightness was on -50% lol) and everything worked but the screen. Ended up being a hardware problem.

Thanks for the suggestion. I cannot see even the faintest of light, just pitch black screen.
It's peculiar though --- the hardware buttons are not vibrating. As if it's not recognizing any input other than the Power Button. And thus, maybe why its not recognizing the volume rocker to get into recovery.

Bump: adb now works and recognizes my device. Open to suggestions!!!
edit: Tried adb reboot recovery ... phone turned off, vibrated, then received no input whatsoever -- however still made the connection noise when plugging into USB. Only solution was a hard reset.

Just flashes on startup. Black Screen

I got an HTC One S from a friend who got it from another friend. I don't have any history on the device. He gave it to me to fix because I'm the only Android user he knows and his phone won't start.
If I keep the power button pressed, the capacitive buttons flash exactly 15 times and occasionally the phone vibrates. I don't have a One S so not sure if that indicates that phone was started or shutdown.
Neither fastboot devices not adb devices shows the device. But every once in a while when it vibrates, if the phone is connected to the PC with a USB cable, it beeps - like it's connected. I don't see Android Phone in Device Manager. But I see a MTP USB Device with a yellow exclamation mark. Uninstalling and reinstalling HTC Drivers didn't fix the problem.
I have tried Power+Volume Down key. Shining a torch on it (seemed to work for a few people), keeping it plugged into the mains for 3 days, kept it in the freezer for 2-3 minutes (also seemed to work for one person).
I think when I first got the phone and plugged it into the mains, I saw a red charging light. But I may be mistaken. In any case, there is no light anymore indicating charging. But I don't think that's the problem.
I have no idea whether the device is bricked or not. And if there is any way to fix it. Samsung has Odin which makes any Samsung phone practically unbrickable. I haven't used any HTCs since the G1 so have not been in touch too much with the HTC development. But from reading, it seems that messing around with Romming with S-ON can cause the phone to be bricked. And perhaps that's what my friend or his friend did. Does this sound like that's what could have happened?
Thanks for any pointers.

I dont think the device is bricked. its just a little harder to press the power and volume down when you see the buttons flashing.
just check and do these steps.
connect the mobile to charger and see if the orange light comes and stays on
if the orange light is there, press the power button and keep your finger ready near the volume down button
you should keep the power button pressed and as soon as the orange light disappears you should press the volume down button until you end up in boot loader screen
give this a few tries and see if the device boots up in bootloader

The problem is that I no longer see any light at all when I connect the phone to a charger. It's probably fully charged. Would that show a green light? If so, that's not visible either. I have a feeling that the bootloader has got wiped out or something.
I read in one post that the phone may be stuck in the QHUSB-DLOAD mode.
So I followed the steps in http://unlimited.io/qhsusbdload.htm. But that didn't help. I don't remember the exact statement since I was running an Ubuntu Live CD. But the gist was that it couldn't connect to the phone so presumably it's not stuck in QHUSB-DLOAD mode. Although the site states that it will NOT fix QHSUSB_DLOAD issues encountered by flashing ROMs - which may well be what may have happened.
I understand that running an RUU for the HTC One S may set it back to factory state. But for that I need fastboot to work.

Nexus 5 - Hardbrick ?

Hey guys,
I need some urgent help.
My Nexus 5 device is not booting. It stucks at the bootlogo then powers off and restarts again.
Normally it wouldnt be hard to fix such an issue but the problem is :
I can't boot into bootloader (bootloader appears for 1 second then phone powers off)
I can't boot into Recovery mode (Recoverymode appears for a second then phone powers off)
I can't get my phone into fastboot mode, - it appears for a few seconds durign the bootloop as an "unknown device", but I am not able to flash a new bootloader/factoryimage.
I tried like every possible option what I can do, but nothign worked for me.
What else can I try since I can' get my phone into fastbootmode?
Bootloader is unlocked
Secureboot is enabled
(from what i can see in these 2 seconds where the bootlaoder pop's up)
Is there a way to recover my nexus5?

Symptoms of broken starter button
Posté depuis Nexus 5 / Miui7 by Miui-France

Remove the motherboard and clean around the power button. When you have cleaned around the power button, quickly press and release the power button using more pressure than normal a few times, try to boot again.

Thanks for the tips!
I never thought that a broken Button could cause this issue.
I will check it as soon as I am home.
But how am I supposed to clean the motherboard, and I don't understand how cleaning the button from the outside
of the case should help to solve this problem.
Can you guys explain it a bit more detailed please? ^^
Are there good and very detailed tutorials for this?
And yes, you ideas definitely make sense because some days earlier when the Nexus5 was still
booting fine, I remember that I sometimes had the issue when I turned of the display with the power button
it instantly turned on again and I had to turn it off like 3-5 times until it really was off (standby).

To clean around the power button, you'll have to disassemble the phone which is not hard to do it you take your time and use the right tools.

I noticed that the issue really was the powerbutton, - however the button was broken and
not repairable by cleaning. To repair the phone I would have to purchase a new motherboard.
In the end I decieded to purchase another phone, just saying that if someone will have the same issue in the future
try to clean first, if that wont help the powerbutton is most likely broken, and this results in a new motherboard-purchase because
the button is not repaireable by hand

The power is replaceable if the damage is confined to the power button itself.

Nexus 5 Android Power UP

Hi,
First I hope I'm posting this in the right place - to get assistance/direction that will help my situation. If not my apologies - please send me to the right place.
I have a Nexus 5, Android 5.0.1, Rooted.
- My device was charging then suddenly went into boot cycle - showing the Google logo then powering off and repeating the same. Trying to get into recovery mode was impossible - would power cycle out of there too.
- I have tried doing the multiple fast press, and sticky button clean solution (actually taking the back plate off etc.) posted out on the net but that has not resolved my issue.
- Left my phone to charge overnight. The problem still persists. More accurately. Turning it on without it plugged in to the charger does nothing.
All the following is the behavior when its plugged into the charger:
- Without pressing any button just shows a full battery charge icon for about 8 sec then the screen turns black for two seconds and that keeps on repeating. If I press the power button it shows the Google logo for a 1.5 seconds and shuts of, going back to the battery charge icon flashing cycle.
- Now if I press the power and volume down button It takes me to the fast boot mode screen where can cycle through the menu's <Start, Restart Bootloader, Recovery mode, power off>. None of the options work. No matter which I chose the phone shuts of and goes back to the full battery icon cycle.
- I was thinking a battery issue but, when in recovery mode the phone will not turn off. I can use the volume buttons to go through the menu as pointed above but using the power button just takes me back to the battery icon cycle. Now I'm not sure, battery, power button or software. What could it be?
I am thinking, try a new battery or, damn buy a new phone (my phone has outlived its warranty). If there are any ideas on fixing this I'll appreciate your opinions. If i have to get a new phone is there any hope of salvaging data. I have a 4 month backup on my computer, but my latest is stored on my phone.
Thanks.

If you run into this issue and none of the solutions in my original post apply, read on in case my final solution helps you out (you might not even have to get paid help if you know how to work on the fault I was experiencing). If not - nothing more for you to gain if you read on.
As it stands:
I took my device to a reputable cell repair shop. After describing to them the symptoms of my device the out ruled the stuck power button issue and tentatively diagnosed it as a firmware bug or nand memory corruption issue which would require a nand mem flash which they had the tools to do. I went for it.
When I went to pickup the device. They reported that the device was functional and they did not even have to do the flush. My data is safe. Issue was a loose battery contact which they detected and fixed. It's been 8 hours and all looks good. These guys were going to charge me a $80 bill to do the flash if the recovery was successful, but I had to leave a $56 deposit after tax for them to begin the work and pay the balance if the procedure was successful. When closing the deal they just gave me the device and said since they did not have to do what they anticipated, the deposit I left them was satisfactory.
I have my device back and working (at least for now) and have the chance to make external backups incase the issue reoccurs. I'm happy. Cheers.

Zenfone 5 Selfie/Lite (ZC600KL) stuck on ASUS logo

Hello! I could not find a section for my phone, so I am posting here.
My Zenfone 5 Selfie/Lite (ZC600KL) randomly "bricked". After being left alone charging for 20 minutes, when I came back it was turned off. Holding the power button resulted in the phone showing the "Powered by Android" logo, then the ASUS logo, and stop there.
I don't think it's a battery issue as it always lasted a long period of time; this is the first time anything like that happens, and might be the last. I also never tried meddling with my phone (rooting or the likes of it), so I'm pretty much clueless. I messed around with the phone, turning it on and off for a while, letting it run out of battery and charge it again, leaving it stuck on ASUS logo over night, to no avail.
Here are some things that I noticed that might help solve this problem:
1. After I connect the charger, the screen shows an empty charging battery along with the LED showing the red color (which means no battery). After 5 seconds, the screen turns on again by itself to show the true state of the battery, which is whatever % it is right now and the correct LED light (orange/green).
2. Turning on the phone makes the "low battery" buzz followed by a normal vibration. If it's charging, the "No battery" red LED shows.
3. I can turn on the fastboot mode by pressing Volume + and Power, but it only shows "CSC Fastboot mode!!! Long press power key to shutdown device". While on fastboot, my computer recognizes the phone is connected through USB, but I cannot access the phone's storage.
4. Pressing Volume - and Power does nothing besides restarting the phone.
My english isn't the best, so I apologize. If there's anything that I messed up and you can't understand, please do tell me.
P.S: Zenfone 5 Selfie is the same phone as Zenfone 5 Lite, but it is known by both names for some reason. Thanks for reading.

Exactly the same problem and phone I have here and Google research has been useless plus it appears this model phone has many firmware versions also
I have tried flashing firmware in fastboot mode but the ADB and fastboot tools won't work as it shows write protected as it appears bootloader is locked and am struggling with QPST also got so desperate to get phone working I even checked out some of those android repair software like DR fone then realised they want $70 USD and instantly removed the software haha
Hope we can get answers but seems like that maybe no one has solutions for this
