Hello people, I have a big problem, i put rom revenge, but one day for other the display, only show the light and touch button. After this I have buyed a new display for try to work, but is the same thing. What is the problem and how to resolve, thanks
Heyyo, hmm, and holding down power and volume up or power and volume down doesn't eventually reboot to fastboot or TWRP?
If still no display, unfortunately it sounds like you have to attempt qfil.

I make qfil and continue equal. The problem, is hardware but I don't where. The mobile work all normal but pixels don't show the display is all black, but show the button light and display light.
@Gaftuga , sorry I don't quite understood what you wrote. Can you please try following the QFIL guide? It should teach you how to put your phone in EDL (Emergency Download Mode) and in device manager on Windows you should see it as QDLoader 9008 driver. Please check the guide I linked.
I bricked my x2 before (testing OnePlus 3 device firmware on x2... Bad idea lol) and it was the same as yours where the LCD backlight turns on, but the display never shows anything and the hardware buttons light up. After QFIL, my x2 works again as I am using it right now to write this and has been fine for over four months.

Hi All,
I have flashed EUViewPad 7 based on Stock rom. installed SD Card Booster, CPU Master and etc.
The flash is fine since I managed to boot it and install several apps.
Until I needed to reboot the device since the hacker keyboard always forces to close. I rebooted it and poof I am in infinite boot animation without a way to remove the battery. afraid to fiddle just waited the battery to drain so I can test again(This happened on my O1. just removed the battery, put it back and its ok)
I have drained the battery after almost 8 hours of non stop boot animation. But this device won't turn on anymore. It just vibrates when I press the on button.
Tried opening the back(crap I have scratched the back covering. now it has large scratches ) but the battery is taped . My question folks is what is the possible solution to my problem aside from removing the battery(can't even get to clockword recovery)
Thanks
Not too sure about your device, but doesn't yours have a reset button like the viewpad?
Should be a small hole on the bottom edge right next to the microphone.
Try pressing that with a paperclip if you're having boot problems.
Anyway, if you've drained the battery completely, make sure to leave it charging for a little while. Too low battery voltage will make it unable to start. 15 mins or so should be more then enough.
Try starting with both volume buttons + power pressed. Keep holding it until you see "entering recovery mode."
Let me know if this gives any results.

Ahh I have that reset button beside the microphone hole. Will try this later on. Thanks for your help and for your custom rom
Uh oh... Tried pressing the small hall beside microphone, pressed on button. No luck. tried pressing that hole and on at the same time No luck again.
Is it possible that it will mess up the whole boot process due to boot animation loop??

I'm afraid and it sounded like, from your descriptions, that the boot process has been messed up .... so, what do you got to lose by trying to "wake" it up or at least respond to commands, right ?
Try holding the power button & use a small pin to press RESET - leave it connected to the power supply/charging unit.
Try holding both volume Up & Down key & use a small pin to press RESET
Try holding both volume Up & Down key along with the Power button at the same time, and press RESET (you might want to get someone to help you to this)
Try holding the volume Down (left) key & Power button, and press RESET with a small pin.
Does any of these work in getting the screen to show life, be patient as you might have to hold it for 10 to 30 seconds before it cycle & restart/display the 3 birds ...
Chances are you will need to flash a stock ROM with the SULT3 utility, and then if successful, root it again & start over (carefully) - it might work or it might not even connect via usb at all .... worth a try, got nothing to lose at this point.
As a last resort, contact Cherry Mobile and get it repaired & sending it back to the shop .... check the warranty details in your locale, opening the rear case & exposing the battery, might or might not void your warranty coverage.
Hi Letiride,
I have tried the combinations you have specified but no avail. I can't boot this so my PC with correct drivers cannot even recognize i plugged this.
Is my Tablet already bricked?? I have bought this second hand so no warranty already.
Huhuhu Did I already have one of the "Vibrator" Android phone

Oh mine, no - if it won't power up or boot into Recovery or FTM mode, I'm afraid it's critical if not officially certified "paperweight". Try uninstalling your PC's usb drivers for the device, or use another computer & install SUTL3 utility from Viewsonic, and see if it can at least beep & signal some USB sequence loading the drivers.
Here's a link to Droid Explorer posted elsewhere in XDA (instead of pointing you to "Search" for it) Install it if you can get the yours powered on, but use it with care as it's a very "powerful" tool to explore all the hidden workings of the Android device(s).

My feeling is that the core image & boot file(s) were corrupted, damaged & overwritten, and it need to be reformatted & reflashed from a stock *.nb0 file, someone with adb might be able to - maybe, just maybe - rescue it.
Let's see if one of our fellow developers might have a better solution on where to begin b/c this is about as far as I can offer - well, you can always put on eBay for parts & hoped you didn't spend a lot as 2nd. hand.
Uhhh looks like i have no other choice but to have this repaired at service center and pay
So I've had my atrix unlocked for some time and have had Epinter's android 4.2.1 running on it smoothly. One day I tried to turn it on and it would only go to the boot logo screen (Motorola for stock) and i cant enter fastboot by using the volume keys. Further, the status light never lights up. This may have happened about a week after installing winterboard (port from iOS) probably a dumb choice, but.
can anyone advise if this is bricked, or a way i can get into fastboot and wipe the thing? any advice is appreciated
no input?! I just read somewhere i may be get it into AP fastboot by holding down both volume keys and power button. would love to get this phone working again!

So if you read something, why haven't you taken the initiative to try it out?
I have. And no luck. just says unlocked and will not toggle through options (fastboot etc). I included it in the post so it wasnt a lame 'bump' post. but thanks for your lame bump post.

Just so we are sure, you were holding down the 'Vol down' key while simultaneously pressing the 'Power' button and the text 'Fastboot' didn't show up, is that right?
Also, did the phone have CWM installed?
Yes. clockwork is installed. Yes I held volume down and power.
If you notice when you cold boot your phone a status light appears before the splash screen, and then turns off. Mine.. Doesnt ever turn on.

^ Unfortunately, that does not sound good at all. Did you have the 'fastboot' options (and the other menu items) enabled before? Would you happen to know exactly what made it go away? Because without that support, there's very little you can do.
You could try charging the battery separately, but I'm not so sure. We might need to know what was done/flashed to get into this state.
Press power + volume up, does it do something?
yes I previously had the option to go into fastboot and the other options (bypass motoblur etc) neither volume up nor volume down get me to the other options - it only stays at saying 'unlocked'.
Maybe the volume keys are broken?
I did install Winterboard by Saurik and that may have caused this problem.
I have used a different battery/charged the battery separately and still nothing.
i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

Is there any software or commands I could use to diagnose my phone over USB? The screen is black, even during boot (no logos), but the phone is still working in the background. The notification LED blinks normally, menu and back button lights up when pressed, and it even rings when someone calls, though I can't see who it is b/c of the black screen. The screen is not cracked or damaged, and I didn't drop it, so not sure why this is happening. I want to test the GPU or other components before I put down a lot of money for a new screen and it no resolve the issue.
Phone is a rooted SM-N910V that has been working great for 3 months.
Thank you!

Thanks for the suggestions, though I have already tried all those plus other things.
I've left the battery out for over a day, removed sim card, held power button in to drain any residue power.
I'm lost as to why all of sudden the black screen. Hoping there's a way to test the phone to confirm if its the lcd or something else like the gpu chip. On a laptop you could plug a monitor in the vga port, don't guess phones have this option

I read that the phone was rooted so maybe that custom rom has some bug and that way you get black screen .
Try to flash him back to stock firmware and see if the problem is solved .
It is just rooted on the standard firmware, I didn't install any custom firmwares. But I was wondering if I could possibly reflash it from a backup I made with twrp. I cant get to recovery, well actually I could if I new the exact steps since everything works, I just cant see crap.
Is this even possible or is there another way to access twrp over the usb?

So I wanted to put my new Lenovo 10e into developer mode so I could install non-playstore apps on it........The method that is universally shown online is to power down the device, then hold volume up, volume down and power button all at the same time for 5-9 seconds.
In all the dozen or more videos Ive watched and articles the screen goes into a special menu and they click this then that and boom.... Developer mode.
Mine does not do that. the light on the power button lights up and the screen stays blank..... That's it...... No menu, no nothing.
Is this tablet different in some way? Is there a different procedure I need to do?
Any help would be greatly appreciated.
I just did it to mine!! Follow what @AMilkyDeveloper says at this reddit link:

then, when you get to the correct white screen follow up with the proper choices in this youtube video:
