[Q] Help!! a100 Blackscreen

i have a a100 with the latest flexreaper rom installed and im stuck with a pretty serious issue:
a couple of days ago the tab was acting real slow and sluggish and getting bad battery life didnt think nothing of it so i just rebooted a couple times and left it alone . all was good untill the battery hit 10% and i plugged it up using the factory ac adapter. the next day (maybe 6-7 hours later) i went to turn it on and nothing no vibrate no screen flash nothing; other than the power button turning blue as i pressed it and it would stay on for a couple hours but still no other response from the tablet.
im at my wits end on what could be wrong and now i got my wife with her foot on my neck till i get it fixed. can anyone help me?
ive tried to do a hard reset with the reset button tried to boot into recovery /bootloader no dice
(also my home button flashed a couple time i pressed the power button) dont know if its relevant but wanna get as much info out as possible

wondering if anyone can help me...

It may take awhile for someone to see this and form something to try, random bricking for no reason is rare, its almost always some error by the user. However have you attempted adb connection to it? Leave it powered off, connect to the PC you used to unlock the boot loader then power on. Does the PC make the USB connect sound? Does the Acer vibrate? Did the home key blink again?
It really sounds like your boot partition is wrecked which wouldn't normally happen outside of flashing. If boot loader is trash then it won't know what to do and just sit there. No recovery or anything else.

it made something like the connect sound but instead of the regular duh doom sound it did a dadadoom (kinda hard to describe the sound) but it was faster than ive ever heard the connect sound before which is weird. the tab didnt vibrate and it seems the home button blinks when the tab is dead and needs recharged

Yeah I know that sound it means USB connected but error for some reason. Its been shown if this thing dies all the way down it wont read the battery correctly and probably needs to be sent in. Before that I personally would unplug it open it up and remove the battery for awhile, maybe an hour then put it back and plug it in. But thats me, not the advice I'm giving. If you have warantee on it use that.
The batteries on a lot of devices and laptops etc have something of a fail safe, if the voltage drops below a certain point it trips to prevent cell damage, however it renders the battery useless.
I haven't searched out much past that if a reset is possible by us, but it seems the pack is trash after or needs sent in.
Since this is a sealed unit you void warranty opening it (well unlocking the boot loader did too) so you can't send it in for repairs without paying for it.
I hope someone can jump in and help figure this out, and prove me wrong.

Weird, This exact same thing happened to me. Used it in the morning and now after work it won't turn on. I had already tried disconnecting the battery, but hadn't thought to leave it disconnected for an hour. My tablet has been running the leaked ICS since it came out and The last factory reset it had was about a month ago. It was working fine up until this. The power button seems to be responding correctly, the issue is that after the LEDs light up, there is no vibration or display. I hope someone can help us with this issue.
EDIT:
It won't connect in ADB mode. It will only appear on my computer as an APX device and since there is no vibration I am unable to boot into fastboot. Any help or suggestions? All the threads I have found have involved booting into fastboot.

i am also having this problem. i set ti backup last night to save to box i turned it on this morning it.worked set it on the charger came back to a frozen screen. I turned it off now just a black screen it turns on or the home button dose but nothing comes up on the screen

same thing here.

I have been using ICS the leaked one, and last night I was goint to check my email and it did not turn on, I though the battery died. I plugged to the charger and this morning I tried to turning it on but it failed. I did the reset pin but nothing. I connected to the computer and it was recognized as a APX device and installed a driver ACER Picasso USB recover but i cant access anything. I am a nob. Thanks

i am also having this problem. last night. just a black screen it turns on or the home button dose but nothing comes up on the screen. :crying: Help!!!!!!

Has anyone tried holding the power button for a while? Laptops do this too, if someone felt ventures, try taking the battery out and hold the power button. No promises, might work.

Having the exactly same issue, here...
I also tried to hit the hardware reset button and it does not help.

If the screen is blank while powered on its in failsafe mode, in other words is bricked, has to go to Acer.

This just happened to me a few weeks ago as well. If you are still under warranty send it in to Acer, thats what I did. I just got an email saying they had fixed it and were sending it back for free!!
At the time I was on the 9/02 JB build. I wonder if this issue is caused by faulty hardware or if it is an issue that was made by rooting and unlocking it? I don't know enough about this stuff to answer that though, but it does make me think whether I should root/unlock it when I get it back or leave it stock.
Also thanks Pio_masaki for helping me a few weeks back wasn't sure if I was even going to send it in until you said they most likely won't be able to tell.

I highly doubt they even CARE when sending these in. They will void for physical damage most likely.

Ohmygod,

My Xperia Arc S doesn't want to turn on anymore

Hey
My phone stopped working.
A few weeks ago it suddenly didnt turn on anymore
The evening before i put it in charge coz it only had 6% left.
The next morning it didnt do anything
no led light, didnt turn on.
When i try to boot fastboot mode, the light doesnt turn on. when i put it in charger, the light doesnt turn on, my computer doesnt recognize it.
i tought lost case, its dead.
but this morning i tried to turn it on one time, it didnt work. i put it on my desk. i accidently wiped the phone off my desk, it turned on.
It showed Sony Ericsson logo, as im used to, the screen lights up very bright for a second, normaly the key lights and the led should turn on, that didnt happen.
then it went to a black screen, and turned off after a few seconds.
after that it didnt turn on anymore
Maybe the worst part: coz my father is going to buy an iPhone 5, he wants to give me his 4
is there anything i can do? I no longer have warranty.

Have you tried removing the battery, pressing power, then letting it charge for a couple of minutes, and then try to turn it on? Maybe it's really completely empty.

You had anything custom in there?
Did you use the original charger?
As I can understand, phone does not go into flashmode (while turned off, back button and connect USB cable) or fastboot mode (same thing but menu button)?

[Q] Help - Glide crashes and restarts

I bought a Samsung Glide i927 phone last month in the US, i bought it unlocked as i am from argentine, and i wanted to use it with movistar.
Recently the phone started to crash a lot, by that i mean that the screen starts going white, with horizontal lines and pixels of different colors appearing, then just turn off or restarts itself, only to crash again as soon as it starts an then turns off.
When this happens i try to start the phone and select the shut down option myself to see if the next time it starts it doesnt crash. But sooner or later it happens again.
This problem its happening too often, and not while doing something in particular like running an app or something. Sometimes it crashes just by plugging it to the power adapter, it even shows the white screen with the lines instead of the charging battery image when i charge it while turned off. I have already try to fix it upgrading android or doing a factory reset, but that didnt work.
Anyone have any idea of how to resolve the problem, or if its a hardware malfunction that cant be fixed?
To make things more difficult, as i said earlier im from argentine, and i cant go to AT&T or Samsung to get it fixed or get a replacement. English is not my first language, so please forgive my orthographic mistakes.
Thanks

This really sounds like some hardware problem, but to be safe, learn how to use Odin and use it to revert your phone to completely stock condition (cleaner than factory reset).

I tried to do that, but the first times when Odin try to reboot the phone it just freezes and i have to unplug it. After many tries it finally finished, but the phone keeps freezing and crashing.
The phone even crashes while turned of and conected to the power adapter.
Do you think that with LiteROM 0.9.0, that might fix this issues?

I've got reboots too, try to disable auto brighness
It helps for me

Power button issue
I am having a similar problem. At first, it just happened on rare occasions. However, today, it started doing it repeatedly. The phone was unusable. I did some checking around, and it appears that the power buttons on Samsung phones are prone to sticking. Some people suggest you actually remove the battery and slam the power button against a table. I wasn't going to do that, because I could just see it doing even more damage. What I did instead was firmly tap the power button repeatedly. It seemed to unstick the power button and allow the phone to function again.
Another alternative is to have the power button replaced, but that might be a hassle.

First of all, sorry for my bad english.
I bought it on amazon a few days ago, I have the same problem...
I thing aznemesis is right, because my power buttom is very sensitive, in fact, some times, when I press the button smooth and fast, to turn off the display like, the typical menu appears as if I had pressed the button for much longer period. Which proves your theory. The problem is if I hit the button over a table and the button breaks here in Chile do not exist spares of the terminal

Well, I did. I couldn't stand the desire to do so. After nearly 18 hours, the terminal isn't rebooted again.

The horizontal lines on the screen sound as if it is an overheating issue. What were you doing before your phone shut off? Are you using the factory charger?

cure found
take the battery out...blow on the power button with some compressed gas to get the dust out....then pour a drop of silicone based lubricant on the power button so that most of it gets in the gaps...then hit the power button a few times....haven't had any reboots since then

[Q] Phone stuck in screensaver mode

Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?

Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.

Have you tried factory resetting it?

Yes, but it didn't fix it. The problem still occurs.

tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA

Same problem. And I guess this guy has it too.

Black Screen

When I was using this phone the screen suddenly turned black. No powering off or anything, the phone was nearly fully charged anyway. Nothing seems to be working anymore. I tried turning it back on but it's completely unresponsive. It won't even charge anymore. I was wondering if there was any solutions to this and if other people where having this problem or did my phone just brick itself

Are you able to get to the bootloader? by pressing volume + and power at the same time. It may be worth trying to flash stock also. I am no expert its just what I would try.

Of course I did. But at no avail. Today, I found out, that the new screen is partially working. I can see very dark picture, it means, I have no back light. Tried to set it up from engineers mode, but no luck.
So the new screen is on, but without back light, and the phone heats pretty much in the top area.

If so. Try to pull down the statusbar and swipe a bit under the statusbar line, in the top of the screen from left to right, with some luck you will tap the brightness switcher

I can connect to the phone through Vysor, and when I change the brightness level there, there is no change at all. The Phone does not react to any settings change at all.
Tried eragon rom, but still no change....

Better hope you still have your garantie, because theres legit no way to restore it. You just have to send it back for it to get fixed. This happened to me once and yesterday twice. sadly I am to dissapointed from this. I am never buying an Elephone again ! PS bro it isnt worth sending this hell of a **** peace back. It costs and the blackscreen thing is gonna happen again in 6-8 months. SO go out there and buy yourself a real phone not this bull****. I have to do the same rn.

Just happened to me with my 3 year old phone. Left overnight with enough charge. Pressed the side button and nothing - held it down to restart and then complete blank.
Repalced the battery about 1 month ago with one from AliExpress for £5.
So using the kit provided with the battery or a watchmakers screwdriver - undo the 12 tiny screws and remove the white surround and then the inner back with the phone's number on it. Next disconnect the battery socket but be careful as it is tiny - use a torch and magnifier if vision not good. Remove the sim card. Wait 10 minutes - did this with the blue light flashing - it stopped finally on disconnection.
Put it all back together and hey presto fully working phone
