[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,
Same here, but it's 3 years ago. Sorry for digging the topic. Still no hope? I still keep the tablet and have just buy another refurbished mainboard to replace but still no vibrate and blacksreen still there.

[Q] Help Dealing with Unresponsive Screen/Buttons (Probable Water Damage)

On Friday night, My phone was in the breast pocket of a blazer that got very damp in an unexpected downpour. The phone continued to work on Friday night as far as I recall (I wasn't using it much, but I'm pretty sure I did use it some). When I woke up on Saturday morning, it appeared to be off and wouldn't turn on. I pulled and replaced the battery and still got nothing. I put it on the charger, but I had to run out, and I ended up being gone all day.
When I came home, the power button still wouldn't turn on the device. I pulled the battery and replaced it, and the Google screen came on, then the CM10 boot animation. When it got to the pin screen, however, the screen wouldn't respond to me entering my pin. Then, after a minute, the screen turned off, and the power button wouldn't turn it back on. I did a battery pull. Again, replacing the battery brought up the google screen, the CM10 boot animation, and the pin screen. But, again, the screen was unresponsive, and the power button did nothing when the screen went off.
I took it apart and left it alone all day Sunday. On Monday morning, I tried again and got the same results. I went and picked up a bag of white rice yesterday and left it in there last night and all of today. Still, I've got the same outcome. Buttons and screen are unresponsive.
So I'm left with a couple of questions:
First, is there anything else that can be done? This seems to me to be water damage. Does anyone have any suggestions for possible solutions?
And second, I keep getting text messages. Is there any way to pull those messages using the Toolkit or adb or anything (I'm pretty inexperienced with adb)?
Any help would be great. I'm stuck in China without a phone right now, which is a pain in the butt. I'd like to revive this, and I don't want to go track down a new phone until I know this one is sunk. Thanks for your help.

install android-sdk
run adb server on the host
connect your device to pc (feed it naked drivers manually found on dev section, if you're on windows and device manager shows unknown device)
type: adb devices
q: do you see your device listed? (should be lots of numbers and letters)
if it doesnt even recognizes that it has been plugged in, then your usb connection went down the drain, nothing else you can do

My computer recognizes the device, and I'm able to do some things using the toolkit, such as a manual reboot, so I think my usb port is intact.

then i would reflash google factory images per this guide and return the device. unless you want to DIY (open the device, etc etc)

And you would expect this to resolve the screen and buttons being unresponsive? This is interesting. Is it possible to pull my messages beforehand?

Galxy s2 Vibrating and crashes at loading bar.

So i've looked around and no one that i've seen has the same exact problem as i do. Here's my post in another forums about my problem.
Here's my story about my Galaxy s2 for T-mobile. My phone randomly turned off 2 days and whenever i tried to turn it on, it would restart and basically never get pass the blue loading bar screen. Second, i found out about this boot loop sequence and i was able to do a factory wipe.
After i factory wiped the data etc off the phone, i was able to use it until it ran out of battery, but then after i found out it ran out of battery, it wouldn't let me turn it back on, it wouldn't get pass the loading screen, once again. On the other hand, i am able to go to recovery mode or download mode, but the phone shuts off before i can even try and click on the options i want.
Today, i found out that if i kept pressing power button consecutively on the phone, I'd be able to go to my home screen and basically act as if nothing ever happened, it'd function as a new phone! I then had the nerves of turning off my phone just to make sure it finally works now, but my hopes were crushed and now the pressing the power trick does not even work anymore. It would probably work one out of 10-15 times, and in the end it'd still restart. I am using a gingerbread galaxy s2. My friend tried using the usb jib on my phone, and it worked but whenever he tried to plug in the usb, the phone would just restart. I am extremely frustrated with this, and if you can help, please do so because it's important that i fix this phone. If you have any questions, please feel free to ask!
Hi there, thank you for the welcoming me to the forums. No, my phone is not rooted, it has always been gingerbread etc i never tried rooting because i never knew how:/ I believe this started when i was just browsing around facebook, so i'm not entirely sure what happened... Uhmm i tried going to download mode through the volume keys and power button when it's connected to usb to the i think it's odin3? and it'd be in the download mode but as soon as the computer says it's connected, the phone would just turn off again and bam, it's like nothing ever happened. My phone does charge when it's plugged in, but it doesn't show it's being charged but i remember my battery was dead last night and i charged it till today and now it's got power. ANd no i don't have a warranty:/ i really hope you can help me

Sounds like a faulty power button. Check out Mobiletech video for thier power button repair service.

[Q] Why won't my Galaxy Nexus power on?

I have a Samsung Galaxy Nexus. It is had some water damage in the past (making it near impossible to get repaired under warranty) and that has caused it to act funny. Funny = Powering off at random times and rebooting itself/causing the buttons to act silly. Recently it did the thing where it powered off and now it won't come back on. I know the power button still works and it is charging because when I plug it in the charging symbol pops up when I press the power button. However it won't power on. I plug it in to my laptop and it charges but my laptop does not recognize it is plugged in. Is there any sort of program I can download that will allow me to get into my phone or anything I can do? Also I have tried the Power and Volume buttons to try and power it into Bootloader mode but that does not work either. Neither does pulling the battery or putting a different battery in or using a different charger.

Isnt it clear it is dead? Electric stuff+water=death. (Physics 101)

So your galaxy nexus turned into a Nexus 4? Or is there another reason you're in this forum?

Rude
Why are you people so mean? I am looking for help, really just a program that would allow me to plug my dead phone into the computer (since it indicates it is charging) and allows me to get files off of it. That would be nice.

Help

Hey man,
I'm not sure if your gnex is salvageable, but if when you plug it into your laptop it indicates charging perhaps you may be able to get to your data. First question...do you have usb debugging enabled in settings? We have to get your laptop to recognize the phone as a drive,then try to grab the files. Tell me more about what happens when you connect it. We aren't all mean, some here just forget how it was when they had nothing but questions and no answers. Most in the forums are very helpful, regardless of experience level.

Thanks for your civil post, I will try my best to inform you more on what my phone is doing.
When I plug it into the laptop it does indicate it is charging but that is the only sign of life I can get out of it. After reading a little bit more on the issue I figure might be the power button that is the issue since it is running JellyBean. One solution that I have tried that has yielded interesting results is plugging the phone into the laptop via USB without the battery in the phone. My computer then makes the "beeping" sound like it is connecting to it and then "beeps" again like it can't connect.
I can't post a link but if you google katzz ifixit then you can go to the website I went to that described the issue and gave the solution I just described. Katzz is the name of the user who posted the solution.
I'm pretty sure I have USB debugging enabled in the settings because before my phone stopped responding I plugged it into the computer a lot to transfer files.
Is there any sort of program that would allow me to turn on my phone from my computer even though I can't seem to get my computer to recognize my phone?

GN doesn't boot or turn on if unplugged

Hello I have a problem with my galaxy nexus. my dad's using it and yesterday while he was browsing the phone shut down e turned on only if plugged in. So today i'm trying to figure out what's the problem.
If unplugged it doesn't turn on in any way, it's like dead. When I plug it in i can only turn it on in fastboot mode but i can't enter recovery or boot the phone, if i try one of those it goes to the google logo and then turns off or return to fastboot and if i unplug the phone while it's in fastboot it turn off immediatly. I also tried to turn it on without battery and sim but nothing.
Oh and there is one thing my dad noticed yesterday. I gave my phone to my dad to subtitute his huawei y530 and copied on my GN photos, music and contacts. Yesterday when the phone turned off he said that for like half second he saw on the screen the huawei logo, and i can't understand why.
I also tried the procedure described there http://forum.xda-developers.com/galaxy-nexus/general/bricked-gnex-brought-to-life-t1760787 but nothing.
hope someone can help me, and sorry if english is not perfect.

It might sound a bit like a battery problem here. Try to take out the battery and plug in the phone the try to start it. If it does not work, via adb try to flash a Google Factory image for GNex. This is all I csn think of right now

I can only access fastboot mode (where you have to select to start the phone normally, in recovery or reboot bootloader) and if i remove the battery the phone shuts down, no matter if it is connected to AC or USB.
If i plug the phone in to my pc usb (with phone turned off) i can hear the sound of the usb connection and after a few seconds it disconnects and keeps doing that over and over.
