[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,

[Q] Galaxy Nexus CDMA, soft bricked?

So I've done all the research I can and can not figure out what I should do about my phone.
The complete story:
My power button was not responsive starting last night, after pulling the battery the phone began to work fine. The issue happened again today so I did a Backup of the phone using Clockworkmod, then flashed on old rom to see if the power button issue was "software related". The power button was still unresponsive and i went into recovery mode, but of course could not do anything because the power button didn't work to confirm any highlighted items. So once again i took out the battery and the phone will not turn on.
What I have done so far:
1)Plugged the phone in w/the battery in, and i receive a battery charging icon for about 8 seconds then it goes away and black screen.
2)Plug the phone into the computer without the battery and the computer recognizes the phone but under devices i get a blinking icon saying "OMAP 44440"
If I can get the phone on, I can gnex toolkit to return my device to fatory but I have no idea what to do next? Please help.

This sounds like a hardware problem. Your physical buttons should be functioning normally when your phone is powered off (e.g your power button). Sounds like you need a warranty exchange.

Thanks for advice, but I've got a couple problems with that.
My phone is rooted and has not been restored to factory because I can't turn it on.
Second, if I could turn it on isn't my warranty voided? And if it isn't voided, given that I could restore the phone to factory; I bought the phone through amazon,so would i contact amazon, verizon or Samsung?
Any thoughts on using a usbjig to start up my phone?

I don't know how but my phone turned on, Thanks for the help.

Issues with booting (blinking orange LED)

Hi there,
I'm having strange issues with DHD. I've read a few threads with issues like this, but symptoms are always slightly different.
Yesterday, I've connected it to the charger (the battery was empty), and when I tried to turn it on, it just did 3 vibrations and orange notif. LED started blinking. When connected to the USB, the Windows recognizes device as Qualcomm, and further reading suggested that the phone is entering service mode, which is normally accessible with Power + Vol+. I've also found out that volume rocker can be the issue, but in my case I don't see anything wrong with it, it's working and looking like before.
No matter what I did, it always did the same, it won't even go into recovery (Power + Vol-), screen always stays blank, the only activity I'm getting are flashing LEDs and vibrations.
Also, phone is charging when turned off (battery removed and reinserted). I've charged it for a few hours yesterday and the green LED was on.
And finally, when turned off, and plugged into the USB, after few seconds, adb devices will show the device, and after the serial number it says recovery. Does that mean that the phone booted into the recovery? The screen is still black though.
So, the most important thing for me is to find out is it possible to return the phone back to stock, in order to send it for a repair. And even better, a solution for the problem

I believe its a hardware problem, although adb says its in recovery. Any more ibfo you could give us? ROM, how you rooted it etc?

thanks don't hurt ya know?

Take off battery,connect phone to charger via USB for 3 minutes ,than insert battery put battery cover now u should see orange light ,now press power button and voila
It's an issue with the volume rocker I think

Had a very similar issue when I had IceColdSandwich on my DHD, only started when I flashed that Rom, reflashed a different Rom, everything is fine again!

I'm not sure that the issue is with ROM, I'm starting to think that it's probably a hardware issue. And that's why I need to found out how to return everything to stock, and send it for warranty.

Try again it will work .may be leave it longer after you put the battery in like an hour .it should work after an hour press the power button

Today, i visit the service, flat cable and battery where reinserted and everything is normal now. You could try this method if you have a warranty. Best regards.

Thankyou so much after leaving phone in cupboard for like 5 years and forgot why it was on there I decided to plug it up. Then I remembered it wouldn't turn on and I was getting the orange blinking. After following your instructions it's all on again. Have upgraded since then so I guess this is a back up phone now lol

[HELP] Screen off, vibrating continuously

Hi,
My phone has been working fine since I did S-off and installed a LeeDroid 2.3 ROM a year ago. This wednesday I had to install another ROM because of boot loop problems with the previous one. I used VJ CM10.1 v5.3 which worked amazing for almost 2 days. Yesterday at night while the phone was charging I couldn't unblock it (black screen) and the orange led kept light event without usb cable. I removed the battery and since then the phone only vibrates continuously when I turn it on. Even without battery if I use an USB cable it starts vibrating inmediatly, of course with any screen response (in the dark you can see a very light attempt to start the screen but nothing else). The PC don't detect anything when I plug it and I can't use any key combination to get to Recovery.
I wasn't doing anything dangerous, only charging but the ROM was only 2 days old. Does anybody now what is happening or how could I fix it? Sorry if It has been responsed but I think not (It's no the 7 vibrations problem).
I can provide more information if needed.Thanks a lot.

Take out the battery, hold the power button for 10 seconds, then try to boot.

Same result. It only vibrates. I'm considering hardware fault (is 2 years and half old) but as I changed the ROM this week seems to be somewhat related.

Before we come to a conclusion, let's try all the stuff we can.
Does the phone boot in hboot?

No, all key combinations apparently have the same result.

The last thing i'd like you to try is putting your phone in the freezer with the battery taken out. Who knows, maybe it will boot afterwards.
If not, then send it to a service.

Thanks a lot, I will try. By the way, I've started saving money to buy the Nexus 4

My S4 mini won't turn on, doesn't vibrate, can't launch recovery or download

So a few hours back I picked up my phone, but it didn't respond. A few minutes earlier it worked fine, and now it just seems dead. I cannot launch recovery mode or download mode. The phone does not respond to me holding the power button or something, there is no vibration and no visuals on the screen. Removing the battery and plugging it back in does not work. Leaving it charge for a while does not work. (assuming that it even charges). When I plug in the phone into my PC via cable I hear a sound that something is connected, but it doesn't show up on 'My PC'.
What do I do?

The same happened to my sister! Nothing worked, probably the motherboard died. Used it at leaset for spare parts for my other s4 mini. Especially the LED panel is so precious, it's cost is like half the price of the phone.

Can the motherboard really die like that? One moment its fine, the next second dead?

Yeah, likely. I ain't a geek or sth, but the same happened to my sister. Was looking for a solution for hours, but it's probably some random variation in voltage or sth that burns some part on it and then it dies. You don't have to crack the phone etc., it can happen randomly.

Wouldn't a broken motherboard make my PC unable to make a sound when it's connected? Also, when it's connected to the PC and i hold the power button for ~15 seconds, it disconnects. This would mean that the power button still functions

Then it's deffinitely NOT completely broken. A dead MB would definitely NOT identify the phone in the PC.
Did u try entering Download mode & connecting to ODIN, trying to load FW again?

I cannot enter any mode. Pressing volume up or down + home + power doesnt do anything. How do I connect to Odin, and whats an FW?

FW = Firm Ware i.e. software that is flashed onto chips. aka ROM.
But if you can't go to download mode you can't flash stock ROM again. So Yes sounds likely some component has failed or maybe just a bad solder joint, a short, etc) which is not allowing power up,( either way you need someone to fix hardware & install stock using jtag for you, probably not worth the cost on our old phones in most countries. but if you can buy a used phone with eg a damaged screen or other problem you may be able to get 1 working phone by swapping parts eg power board ...

The same happened to me last august... I posted here, but no one ever helped me https://forum.xda-developers.com/galaxy-s4-mini/help/weird-bricked-gt-i9195-stuck-black-t3619023 i just think that it's some kind of programmed obsolescence, my phone was 4 years old and it just shut off and never light up again after closing a simple call... F*** Sammy and their timers!

Just happened my nephews phone. Was intermittently responding to buttons and now not at all. PC detects it and shows as "HS-USB Diagnostics 9008" in Device Manager.
There are a couple of guides online for using applications on the PC to interact with the phone using this device ID, but it seems to be mainly focused on LG phones. Anyone know if there's anything that can be done for Samsung devices?

The exact thing happend to my S4, it suddenly turnd of while im using it, did anyone find a solution?
