[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.

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] Not quite sudden death - but still a major problem

So I recently installed CM 10.1.2 on my S3, and everything worked perfectly for a few days. Yesterday though, my phone started acting strangely (lag when turning screen off, registering phantom input, etc) and began rebooting every few minutes. At some point, it ran out of battery - and now I can no longer boot past the CM loading wheel screen.
I can't boot to recovery, and I don't think my phone is taking charge (from my computer or a wall outlet), and the farthest I can get is the loading wheel - sometimes it only gets as far as displaying the Samsung logo, or the Galaxy S3 screen with the android dude at the bottom.
I'm still covered under warranty, and would love to take it to the store for a replacement (I've had battery issues prior to this), but the fact that it can get to the CM loading wheel means that they might figure out that I've rooted and whatnot. But I can't get to recovery to flash a stock image, so...what can I do?

Your best shot is to either borrow someone's S3 battery or buy a battery pack. Use that to restore your phone back to stock (unroot) and then you can go to the store for replacement.

So turns out battery isn't the issue, I used a wall charger to get it to full charge. I can get it to the download mode confirmation screen, and can press volume up to confirm - but my phone reboots soon after that.
Recovery isn't really possible either, I can see the blue text in the upper right but my phone reboots after that as well.
My phone will often show an empty battery icon with a little refresh icon in the middle; does this indicate that it doesn't see the battery as charged (even though it is)?

Yeah I've been doing some research into the issue...
I've noticed that my phone automatically boots when I put the battery in, and that it'll do a quick vibrate when plugged in to a power source (outlet or computer) but won't turn on.
Apparently the phone isn't supposed to boot automatically when the battery is put in, and this could be the source of the random reboots - I think if I can get the rebooting under control, I'll be able to get into download mode and fix it all. But I'm not sure how to do that. Maybe the power button has gone bad, as it also doesn't usually respond when I try to use it to turn on.
If there is a problem with the power button, does anyone have any ideas on how to fix it?

Mine does the exact same thing where I have to pull the battery and when I put it back in it automatically starts up and when I go to download or recovery it turns off before I can do anything

Sounds like power button issue.
I was having the same issues (random reboots, boot loop, powering on when battery put in, reboots in download mode and recovery)
This is not an easy fix. I ended up pulling the power button out and just setting my screen to time out after 15 seconds. Sucks but it works now.
If I ever need to turn off or hard reboot, I stick a pin in the power button hole and push down on the button.

The power button is a common issue for these phones.

[Q] HELP!! Phone won't turn on!

I was working out at the gym earlier today and when I wanted to take my phone out to check messages, my phone just shut off all of a sudden and wouldn't turn back on. I tried taking out the battery and putting it back in and it doesn't turn on when I push the power button. Also, sometimes, the phone would buzz and show the samsung logo and the cm logo, but then the screen would turn black again. I can't go into recovery mode either. When I got home and tried to charge it, it never charged either. It just did the same thing and buzzed and then show the samsung and cm logo and then the screen would go black again. At first, I was thinking it might have bricked, but seeing as how I never did any firmware changes to the phone, it shouldn't have bricked. I only opened the phone to check the time. Do you guys think it's the phones problem? Or is there any way to fix this?
Any help would be appreciated!

Any luck with download mode?

No, I can't seem to get into download or recovery mode.

DO you have a USB jig?

Another battery?

You are holding the power,vol up and home button at same time till the samsung logo flashes right?

Never mind guys. I took it to the repair shop and the guy said that it was my power button chip that was malfunctioning. He replaced the chip and it worked again. Thanks for the feedback though. Really appreciate it.

[Q] ATT LG3 Won't Turn On Completely Unresponsive

I have an ATT LG G3 yesterday it the phone suddenly won't turn on. It was on with mostly full battery and now won't turn on and is competley unresponsive. When I plug it in, no charging light comes on. Additionally I tried the hard reset by holding down power and down volume key; this gave me nothing.
Thinking that it might be a battery problem, I left it plugged in all night. But still nothing.
Any ideas?

I had the same problem and pulling the battery wasn't cutting it. This worked for me:
1. Take out the battery
2. WITH THE BATTERY OUT OF THE PHONE AND NOT PLUGGED IN, press and hold the power button for about 15 seconds.
What this does is it drains all the power stored in the phone and takes the power source away so the phone can fully reboot and refresh the power cycle.
3. Replace he battery and plug in the phone to the OEM LG Charger that came with the phone.
4. Let the phone charge for about 15 minutes then try to turn it on.
This worked for me but some phones are DOA being the phones are still in early production. It takes a few months before they work out all the Kinks.

I figured I'd add my two cents. I had the same issue with my D851 (T-Mobile) version. I was copying a file over my from computer and halfway through the phone shut off. I thought the screen timed out, but it wouldn't turn back on. I pulled the battery, tried holding the power button without the battery for 60 seconds, putting the battery back in, charging without the battery... nothing. The LED would never light, and the phone would never turn on. I contacted LG and it's currently on its way back to them for replacement.

I work for a wireless service provider and not only sell this phone but own one. I also had the problem and unfortunately the battery out power combo did not work for me either and swapping the battery was to no avail. I have seen one other DOA as well. I have noticed the new LG models have had some significant flaws and lemons when they've first come out but I feel the specs and price you get are worth the risk so if this does happen to you I wouldn't throw in the towel on LG quite yet. However the way LG reacts to this will speak volumes to the company's overall success in the industry.

what would happen if I tried returning my phone with root and another rom on it and it won't turn on?
I tried manually going to twrp but went to recovery instead, restarted phone and now it won't turn on. I've tried the suggestions in this thread to no avail.

Won't turn on
My LG G3 D855 first had this problem of restarting on its own when I play with its camera and while restarting, the phone is getting warmer. And now, it wont turn on. I press the power button while it is off, it tried to turn on until the LG logo screen and then it shuts down on its own and restarting non-stop until that LG logo screen and turning off again. When I plugged in a charger, it manages to turn on but only to the pass code part and then it turns off again and the battery charging screen when phone is turn off, is displayed. The battery showed was higher than the battery showed when during the pass code stage. Is it the battery problem? I haven't send the phone to be check yet, I hope its the battery..

Clearing phone
My won't turn on either. I filed an insurance claim and am getting a new one. But I have to send my old phone in. I was wondering how I can get all my info off of the old phone before I turn it in. I don't want some one to get my info that is on that phone. How do I clear it all with it not turning on. Is there a hard drive from the phone I can remove?

yes for i have solution if u want to turn on your phone ...
First put phone on charging and then turn it on after 10sec (dont remove from chargning ) when its completelty on ... then remove from charger ...

The plan: Put the phone into recovery and then push " power on".
The method: To get into recovery, push power and volume down together until you see "system recovery" ( it will take a while- maybe more than a minute) and touch "continue power up" by depressing the power key.

h! i have rooted my G3 and insatll TWRP it works .. but when i press volume down+power button it wont boot to recovery. ? i can easilt boot to recovery using ADB .. but how can i boot to recvery using power and voulme keys ..

http://lgg3root.com/lg-g3-root-tutorials/how-to-manually-boot-into-cwmtwrp-recovery-on-lg-g3/ Said better than I can. Be sure that you are firmly pressing both on the power and volume down keys, at the same time, don't give up- To be sure I have constant pressure, I take off the case. I do this each time I restart the phone.

Oh awesome. I was browsing the web having the same problem and this totally fixed it for me. Cheers!
