[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] 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] Samsung Ace II will not turn on

Hello, new here and I know nothing about rooting nor have I rooted my phone but after looking all over the net I have come here in hopes of finding some tech wizards that can help me.
The Problem:
Turned phone off and a few hours later I tried turning it back on but it only shows the screen with model number and Samsung under it. It shows for a few seconds then the screen goes black and keeps looping like this. I have not rooted or anything. Not dropped in water ( water square is pink though). Phone shows no water damage or corrosion after opening.
What have I done?
I tried booting in recovery and download mode but i have never done it before and I was not successful at getting any other screen besides the model number Samsung screen.
I have tried a different battery after spending some time at the mall (no on carries it any more as it is no longer made) different battery did nothing. Repair guys suggested it may be the button sticking and said hey could clean it for $25. Instead I went home searched the web and disassembled my phone. I cleaned the button areas on the inside of the case and the contact on the inside attached to the circuit board. I have reassembled and it still does the same thing.
After more research I found a video saying to actually remove the internal button from the circuit board to stop the loop (which will leave me with no power button) I have not tried this as I am not that bold (yet).
I am wondering if it is a software problem that can be fixed by using Odin and installing the stock firmware but I just have not found a proper guide that makes enough sense for me to actually try. I don't want to waste my time with something I have never done and make things worse.
I have downloaded Odin and firmware from sammobile but that is about as far as I can go without some hand holding....
Thanks for reading my story any help would be much appreciated.

Try this - Press and hold Volume up + Home + Power buttons together a few seconds, you should get recovery mode. And then find factory reset.

Thanks for the reply. I have tried this many times and tried again after reading your reply. This should work fairly fast from what I understand right?
My phone is a virgin mobile phone (Canada) is it possible they have locked out recovery / download modes?
When I try to start in recovery nothing happens at all. Screen does not light, phone does not vibrate. Again I have never tried this until now so I don't know if the phone ever booted into these special modes when it was working.

It's weird. I found something on page hard-reset.com. I cannot post link here now. I put "samsung ace2 recovery" into google and it was on first page. It's hard reset key combination. Try it.

When you plug the phone into the charger, do you get the battery charging status screen?

Weird bricked GT-I9195 stuck on black screen after Samsung logo

So, unluckily today i find myself here lookin' for help with my phone. I had already took a look on other brick threads, but i can't find an appropriate answer to my problem.
I'm (i was) running lineage-14.1-20170602-nightly, i had ne0zone75's TWRP 3.1.0.0-0, and that's how the brick came in a strange way; i was simply on XDA Labs app browsing the forum, when i received a call. I've answered, and when i shut off the call the phone shut off immediately after. I thought it was a reboot, but keeping pressed the power button didn't switched on the phone anymore. So i've tried to remove the battery and re insert it after some minutes, but the only thing i can get is the screen with the samsung logo that goes all black after 5 seconds. I already had other bricks due some errors of mine in the past, but this time it's really difficult.
1: I can't access recovery mode. Ow, how i wish i could.
2: I can access download mode, but after that i reach the ODIN MODE screen with the details of product binary, KNOX, ecc. the phone shuts off again.
3: If i keep the power button pressed, the phone doesn't starts. It only starts if i replug the battery in, but after some seconds it shuts off again.
4: How could a call as another mess up the whole phone?
5: I didn't installed nothing new from at least a week... yesterday an automatic update of the Play Store took place, but except that nothing has been changed. Nothing of nothing! No settings, no apps...
What could i do? Installing Kies with Samsung drivers could help me flashing a stock rom for example? Because at the moment, there isn't too much that i can do with the phone in this state... I hope this little jewel won't have to become a stone to be thrown away. Any help would be great, and really appreciated. Thanks in advance...

Things has got worse. Now my device doesn't starts at all; no vibrations, no signs of life, nothing. I've tried even to put it for 6 hours in my refrigerator, because i've read that the cold temperature could be helpful to fix some broken contacts on some component, but i'm losing hope 'bout it. I supposed that at this point is something hardware-based and not software, because it's just impossible that a call like an other one could be the cause of this hard brick... The only thing is that if connected to my PC, it is being showed as QHSUSB_LOAD. I'll try some methods that i've seen in other forums, like softwares that tries to fix this, but i think that i'll be forced to buy a new device. Neither an usb-jig could help me to force the download mode if the phone is dead in every aspect... the only thing that i still didn't understood, is if a debrick.img on my SD card (sadly i've read that a microSD class 10 with at least 16 GB is required, and i don't have one) could help somehow on a situation like this one of not. Still no one could advice me with some tip, guys
Edit - feel free to close this thread, I have another phone now
