Screen wont turn on!!need helpp pleasee!! Urgentt - Acer Iconia A500

hey guys,
i have an acer a501 32gb model, last year i rooted my tablet to put a custom rom and for some reason now my tablet wont turn on. Nothing comes up on the screen!! the screen doesnt even turn on..just plain black!! :'(when i plug my charger in, the little light on the side turns on..that the only thing working. I tried doing a hard reset, try to get into recovery mode and even press the tiny reset button on the bottom and nothing happens!!
i have warranty but cant take it back to acer since its rooted and also i misplaced my original rom that i did a back up before rooting it.
any help would be great!!!!

This is probably a stupid suggestion, but have you tried pressing the power button and holding it for several seconds?

I had a similar problem as most phones in Canada seem to have Download/Recovery mode disabled, and here is what worked for me.
Grab something like One Click Un Root (all models), and click one click un root (obviously phone has to be on and plugged into the computer).
This should automatically reboot you into Recovery Mode!
All you have to do is "wipe data/factory default" or something like that (should be the third option).
As it states, you will loose all your data, but at least you will have a functionning phone!
did it work?
Hi. I have similar problem. Can anybody give instruction what can I do?
I have this problem too. Please help somebody
Add me to the list. Bell Galaxy S, went to unlock my phone the screen went black. Now it will not boot into the OS, the galaxy S splash screen displays then nothing. The menu and back button light up, thats all. ****[email protected]@
I have not rooted or anything.
Of course my download mode does not work.. Going to try this one click root thing if I can find it.
NOT HAPPY
This is not working. Probably because the phone is not in USB debugging mode as I can't change it... Is there any other way to get the phone into recovery mode?
**** me
i had the same thing happen to me the other day with my bell galaxy s and my phone wont do the 3 button combo trick. i left my phone plugged in to a wall charger for a while until the back of the phone became a little warm. i pulled the battery and then left the power cord plugged in and put the battery back in. i held the volume down and enter button until the battery charging indicator showed up, then i also pressed and held the power button until the boot animation started (this is the blue moving swirl and music, not the galaxy s splash scree) and then i let go of the power button. it took a few attempts at this before it actually worked, but eventually it will go into download mode at which time you can open the odin app, then plug in the usb cable and flash your phone that way. it did seem to make a difference if the back of the phone (around the camera area) was warm. if i let go of the power button while the music was playing and the phone did not enter download mode i would keep all 3 buttons pressed until it shut down again, then i would only let go of the power button while the phone initiated the charging screen, then once the battery logo was displayed i would hold the 3 buttons again and would just keep doing this until it went into download mode. i have flashed it at least 5 times today and i have been able to do this each time.
i also had an issue where odin would not recognize my phone was plugged in and windows would show a message saying the usb device was not recognized. i left the phone plugged in and while in download mode i pressed the volume up, enter button and power button until the phone went blank and when the galaxy s logo showed up i let go of the power button and the phone would go into recovery mode and then the usb drivers would be installed. i would then do the 3 button combo for download mode and odin would work fine. it took several attempts but it does work. i hope this helps you guys
If I hold all three buttons the splash screen does not come on, it just keeps looping the Galaxy S logo until I let go of the power button....

That's what mine did too, several times in a row and then it worked. For some reason it only works after the battery is charging for a bit and the back becomes warm. then it works at will
No luck. I am probably screwed getting it exchanged now too as I am passed the 14 days from Best Buy.
the on click thing doesn't work, if your phone is already bricked.
also it is not the phone's fault for not working, the phone was working properly before you tried the hacks.
whenever you do these kind of things you know you are entering into the "not supported" "not covered by warranty" zone.
in the worse case scenario, if you can no enter download mode to recover your phone, it'll be to take the phone back to bell and claim warranty on it, and prentent you don't know what happened to it.

Its my fault??
I did not hack my phone. Its not rooted, I did nothing to it.
By "unlock" I meant exactly that, unlock as in swiping the screen to unlock it.
The more I search the net the more posts I find of Galaxy S phones randomly bricking...
on the original message sounded more like you went to Unlock the phone, as in SIM unlock the phone using any of the tools available out there, and there has been already several people which had the same problem.
if you go back to Bell for an exchange, you better not use the word "unlock" rather use Swipe
as the message on the phone "swipe the screen to unlock"
there are no known issue about this causing the phone to brick.
if that is what happened to you, you should have started a new topic for people to help you, instead of hijacking the topic from the OP, as your issue is different from OP, the OP actually screwed up because he/she flashed the wrong ROM to the i9000
... anyways, Does it work if you reboot the phone?
I have rebooted the phone about 100 times. The phone crashed when I unlocked it to check a text I received. (not hacked). Has not booted up properly since. I have found many others with the same issue who have also not hacked/rooted/unlocked/ their phones.
Waiting on Best Buy to call me back. I am so pissed right now, I have been bragging to my friends and co-workers how awesome this phone is, one has already picked one up, I hope his doesn't brick too. Not recommending it to anyone anymore..
did you load a lot of MP3 to the phone?
can you boot into Recovery Mode?
in the recovery mode you can wipe the Cache and wipe the data
that should make your phone work normal again
it'll be best to open a topic to help you trouble shoot your interesting issue, as it's the first i've hear that you get a black screen after Swiping out of the lock screen
I can't get into recovery mode. I have tried every button combination I have found. I had about 2 GB of music on the phone. I also installed the Android SDK to try ADB, but since the phone is not in USB debugging mode it does not see it.

on the other topics relating to the 3 button not working.
have you tried the heating up method?
or the plugging the battery in, when all 3 buttons are pressed? (of course for this one you will need help from a friend, unless you are very skilled at keeping the 3 button on hold meanwhile able to slide in the battery in with out a 3rd hand)

Vega Won't turn on at all. Not even backlight

Just bought my Advent Vega today and was all running fine. Charged it too 100% then turned off and booted into the stock recovery. I then waited for it to show up on the computer as i have already got the drivers installed as i have jjust today flashed someone elses vega on the computer. mine didnt show up and then unplugged it and now it wont turn on at all. Tried charging it and then try booting. Unplug charger nothing. The thing is that the charging light still shows.
Any Help would be great. Dont want to have to send it back for repair. it may take weeks.
Thanks
Alex
Hmmm.... it could be a faulty unit, but my guess would be that you need to try at least 10x to try to turn it on.
I know some people complained that the buttons are very poorly designed and sometimes don't even work.
It's the same for my tablet, the "power/home" button doesn't always work like it should.
Once, I had to retry five times in order to power on the device.
If it's not that it could be some other minor issue, try holding the power button for a long time (8 sec), or try to go into recovery again, or something like that.
a sighn its trying to boot is the blue led under the camera tilt the vega away from you and look at the edge of the LCD it will glow when powering on
have you tried push back button, hold it, then press power button 2 second, the release the power button while still pressing the back button? it should be recognized and can be flashed

Some times this can take several attempts.. and i mean several!
I actually had Audi running and had it connected to the pc so could tell if it had worked or not... not the correct way i know but it worked for me.
Interested to know if you ever got this sorted alcurtis93? I'm having the same issue with a vega where it won't even bring up the backlight. No life in it whatsoever.
A bit of a late reply, but try to wipe your device and maybe even flash a newer custom rom

[Black Screen] S3 neo, READ and suggestions are welcome.

Hello everyone,
I have an S3 neo, it's 6 months old. About 2 months ago i started checking in this forums, and then i flashed cm12, and started adding custom roms to my phone. Everything was well, phone was working fine, and so on.
One morning i woke up and my phone went off, and when i turn it on, it's black screen. I restarted few times, took out memory card, and poof it worked. Was all good.
I left it like that and next morning it happened again. And since then i tried all the ways, like take out battery, hold power button 1 min then try to turn it on after few minutes, and so on. Nothing worked. Pulling out memmory card or sim card didn't work either. It's like this for almost 2 weeks i can't use the phone.
I cant get in download mode or custom recovery i i don't know why it won't react on that. It turns on each time like normally, led notifiaction works, the lights on home and back button works, only screen is black. I can unlock it, and such things but cant see anything.
I even succesfully did a factory reset over play store from pc, but that didn't help either..
Biggest problem is that its under warranty but since custom rom i can't take it to service unless i have money to pay... which i dont
I have NEVER DROPPED it, it was never in water, and so on. Doesn't have a scratch at all.
It even has sound, and everything. Just freaking black screen ....
So what i am asking is if anyone here knows how to remove custom rom and custom recovery over pc,is it possible, without the screen? Any way to do it so i can get warranty back ? All i need is a freaking stock rom and stock recovery and a binary reset i guess. Just freaking would need screen to work for 5 mins eh....
If anyone has any ideas please post them, thanks..

I think you can boot to download mode or revovery. The LED notifi and backlight buttons won't turn on if you boot to download mode or recovery.
Just try to boot to...
1. download mode. Just press and hold for 2-3 seconds power + home + volume down
2. then wait 3 seconds. After that press volume up.
3. Connect your phone to pc, open odin and check if a device is connected.
4. If a device was found by odin - flash a ROM (stock or something else) and hope that this will fix the black screen problem.
Good luck!!
Hi, thanks for ur reply but... My phone turns on when i click home + volume down + power button. I hear sound, blue led notification and so on.......
But when turned on, when i connect to usb odin recognizes it, says connected, and when i try to install the rom i it takes really long and on the end i get fail..*attached the screenshot of fail) I guess because its not in download mode. Any other suggestions how i could get in download mode more?
More suggestions please?thanks
Anyone has any ideas ?
So what all i tried is
Remove battery, hold power button for 1-2 mins, let phone for few mins and turn it on. didn't work
I tried with adb,but usb debugging not on so cmd cant find my device
Only thing left i guess if someone has idea how to get in download mode in some other way or some program that doesnt reguire download mode but can flash rom and etc.
@Crazeh
Take it back to the nearest service center and act the dumb ("I don't know what is wrong with it")
I have done that many times
They are prob gonna call me and tell me to pay for fix
No one has any idea what else should i try ?
try link2sd app form play store. it has the option to boot to download mode. I think titanium backup has the feature also.
My screen is black so i can't do anything on it.....
try to disable ambient screen. report if problem persist
How should i disable ambient screen ? While i can't see anything on phone cause of black screen ?thanks for reply Rox
Anyone?

ok so i think your problem isn't due to any rom but hardware problem
power off your phone remove the back , look on the left you see a little trap , open it , now you see connector it is the one of the screen try to see if you can disconnect and reconnect it
power on your phone and see if it work :fingers-crossed:
Where is that little trap?
btw if i do this will i loose my warranty completely ?

If Odin recognizes it, it means it's in Download mode. The device has different interaction with the host over USB when it's not in Download mode.
I don't see the screenshot of the failure. It may be that something got broken in your hardware, so the flashing fails. There's a known issue with the S3 called "Sudden death syndrome", I don't know if it applies also to the S3 Neo, where some of the memory of the ROM fails suddenly. If that is the case (I'm not saying it is, but it might be), there's no fix other than replacing the hardware.
Odin doesnt go over setup connection. cant post screenshot bc im new to the site. btw im sure the phone is on but recognized in odin...

LG G2 not turning on/bricked?

Hi guys,
I have a problem with my LG. Yesterday i was casually lurkin some internet or whatever. Havent done anything suspicious or something. Then i switched phone off and put it for a while on the side. When I tried to unlock it after that it was impossible. Phone just doesnt respond. I havent rooted it or done anything connected with roms etc, not into this stuff really. When i plug it into charger red LED starts blinking, then LG logo appears, then battery icon and after that its just charging like normally and still red LED lights. Right now its fully charged so instead of red, the LED is green. The buttons combinations dont work neither (hold power,hold power and vol-) besides holding vol+ and power. I have to hold it for a while, then plug into charger and then some kinda download menu appears, but it does nothing too. Still cant start the phone. However few hours ago i just tried holding power for a bit and everything worked perfectly. Then i locked the screen and *bam* bricked again. I know there are many topics like that but i havent found the exact same problem with solution yet. Every help would be highly appreciated. :good::good:
BUMP please any advice. It actually Turner on one more time, but when i tried using power button, at first it didnt respond, then after few seconds it went bricked back. I managed to take off the backcover so maybe there is sth i can do?
I could be wrong but sounds more software related then hardware to me, maybe try to use one of that flash tools or pc suite to do a clean flash and sadly lose all your data.
If that doesn't help idk....
You don't have a backup do you?
No, unfortunately i dont. I didnt expect that to happen.
Yo so I actually managed to turn it on (i ve no idea how) and its working fine. Im scared to press the power button so it will be unlocked all the time. Ive already done the general backup of photos, music etc, but if there is some good app to make solid backup or something please let me know.
Soo is there any other option to find out if it is finally repaired than pressing power button? I can access data on PC so maybe theres the way to fix it now? If i press the button probably it will brick again, and then after couple of days it will suddenly start working, so id rather dont do this..

Samsung S4 stuck on first logo screen

I only use my S4 to listen to Spotify and Podcast, no other apps are present. I use it until I the replacement Headphone thingy comes for my Nexus 5x.
It's my old phone and it worked great until yesterday when my screen went completely pink and then my phone restarted. Now it's stuck on the first logo screen.
Not the Samsung animated logo screen, but the very first completely white text Samsung Galaxy S4 logo, I can't post pictures.
I am using a Cyanogenmod Rom because of the memory leak bug on stock rom.
I can't boot to recovery because it just boots for few seconds, then shuts off, vibrates 2 times and goes back into the boot screen where it's stuck.
The vibration thing happens everytime I try to boot the phone. The logo comes up, it shuts down, vibrates twice and then it gets stuck on the logo indefinitely.
I can boot to Download Mode and I can't boot to Safe Mode.
Any ideas what I could do? I really want to listen to stuff again.
Could be a power button issue. Open the phone, clean the power button contacts with a bit of pure alcohol, quickly press and release the power button several times in a row using a bit more pressure than usual, reassemble the phone, and see if it works.

It's still stuck the same way.
When I got to the Recovery Screen once, the screen turned yellow and phone restarted.
The power button may need to be replaced. Do you have a multimeter to test the connections?
@audit13: I've got a feeling the power button isn't his issue. On a properly working S4 the screen wouldn't flash a particular color before rebooting. Given that this happened to him suddenly, I think he has an issue with the SoC itself.

I have a almost dead S4 i9515 model here, it stopped working.
Here at home I plugged it in and it vibrated continue and nothing more.
Tried a couple of times to go to recovery (unrooted, so the standard recovery) and one time I got a Samsung logo with something blue in the top left side of the screen and nothing else.
Cleaned the power button and started the phone and got the Samsung boot logo, but it got stuck in the logo loop.
How can I check the power button with a multimeter? Is there a trick to get to the connectors?
You need to remove the back frame to access the power button connectors. There should be there of them. Without the power button pressed, touch the probe across the outer two and see if there is any current being passed.

Will try it this weekend, if it is the button I will just take it out, and try it that way till I get a new button.
Thanks for the tip!
Well, the button was not the problem, see next post
While starting it won't pass the Samsung logo boot,
while starting via recovery (power, home vol-up) I still won't pass the Samsung logo screen, but now with the message in the top left screen 'Recovery Booting...'
It's dead I believe, the power button is okay, but after a few difficult boots, it wouldn't pass the Samsung logo.
But now it doesn't respond at all anymore.
Is there a way to access this phone?
Via adb or Odin? I don't think so, if the phone doesn't startup I can't do anything...?
It is bye S4 I guess...
I am blocked here too with a GT-I9506, and can't fin anything, so yeah, i guess it's dead, mine too
Time for something new...
Anyone managed to revive his I9506? I have similar problem, if you can guys look into it and tell me that you have tried this already:

I think it will be the best way. It's third day of flashing stock firmware from 4.3 to 5.0.1 NEE an TPL. There ware two times that phone actually booted to recovery and green android appeared. But then phone rebooted and still can't get up.
