[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.

Phone will not turn on

My phone worked perfectly fine for months until today. My cannot boot. When I turn it on it goes to the galaxy s3 screen before turning off. I have tried taking the battery out, sim, you name it and I still get the same result. Does anyone have any tips for me? Thank you

If it also happens in download and recovery mode, power button might be stuck. That or hardware failure.

I cant even get that far into the phone =/
But I think something must be loose in the phone. I got it to boot up but it was very jumpy and hard to get off the unlock screen. Should I try to open it up and check?

Good way to tell if it's a power button issue is to remove the battery, then put it back in and wait a min. If it tries to turn on by itself, the button is your problem.
If it doesn't, it could still be the button though. It won't rule it out but is an easy way to confirm it most of the time.
What do you mean by its jumpy and hard to unlock?

[Q] SPH-L710 reboots in recovery Battery, power button issues possible

I have read the other posts regarding the rebooting issues of the Sprint Galaxy S3 variant, but I seem to have a touch more difficult problem. My phone constantly resets and seems to be getting worse. It now will reset in the middle of recovery. I was able to wipe the cache and dalvik and then it started resetting even more frequently in recovery and made reloading the rom impossible. It even resets in the download screen. So it makes it impossible to use Odin and other applications. If anyone has any ideas let me know. I have a few possible options that I am pondering. The following is what led up to this if you need some background:
A week ago, I noticed that my battery suddenly was not charging when wifi was on. I turned it off thinking it was some glitch and reset the phone and plugged it in to charge. It said it was at 100 % some hours later. then I turned it back on again and within a couple minutes, it said it was at 22%. So I hard reset and then plugged it into the wall, but it was still not charging. I had go somewhere,so I plugged it into the car charger and enabled fast charge. I turned on my data and all the sudden it rebooted, lost my wifi password, but when it came back on, it was charging properly. So I thought it was just some odd glitch. Charged properly for days.
Then I noticed the phone starting to randomly reset maybe once very other day when texting. I was actually going to put on a new rom tomorrow thinking maybe my old one had become corrupt. Then it suddenly increased drastically tonight to where it was starting to reset constantly. I thought maybe the button was stuck, and pulled off my otter case to make sure it wasnt being pressed down oddly, but it continued. Then I went into recovery and was able to wipe the cache and dalvik before it got really bad and now it won't even let me stay in recovery for any length of time. I almost got a rom loaded when it reset and its been resetting faster than ever. Becoming unresponsive to button presses as well. Even when I could get into the recovery, it would keep showing "swipe screen to open," as the power button was apparently continuing to activate or the phone was trying to reset itself. And yes, I have tried a battery pull several times and then tried to get into recovery, only to be booted out right as I see the recovery screen if I get there.
So that is my problem. I can't flash odin or anything else as the phone just keeps resetting. Part of me thinks to get a new battery and try to see if that doesn't solve my issue, as maybe the battery is causing the phone to reset? But part me is also thinking maybe the power button has gone sticky suddenly? It won't charge it seems as the red light will not come on and it keeps resetting before the battery charging icon can even come up. Any help or advice would be appreciated. I am leaning towards the battery going bad suddenly and shorting out the phone. I now have the battery, which last I saw was at 48% (It was charging when this happened), out of the phone and am waiting till morning to hopefully pick up a new battery. But I would appreciate any insights into this issue.
Thank you very much

Same issue
I'm having the same issue described above with the S3 constantly rebooting. I can get into download mode but it restarts a few seconds into the flash. I have tried a different battery but that did not solve the problem - I am also thinking it's a power button issue... any suggestions?

I just had my phone replaced for same reason ( Thank god for insurance) Download mode would last about 5 seconds, Recovery would do the same. I managed to get a stock restore with flash counter reset to boot as i was walking into the Sprint store for the techs to look at this lol.. Same exact thing happened on my S2. Power button is done. If you have INS call and get it replaced (Took me about a week for new phone)

I read some post on possibly using Samsung Kies to flash a new ROM, but that was for the international version. I would be curious if anyone has ever tried this or if its possible to replace the power button with a part replacement? I have ordered an S4 but this time I will make sure to use the home and left touch pad more often to unlock the phone and save wear on the power button. I wold still be interested f anyone has found a fix for this.

So after looking around, I am pretty convinced this the power button,as people describe on this question. If you don't have insurance, I see there are selling replacements or you can pay someone to replace and fix the power button fairly affordably on ebay. I might go the second route, as I want it fine right and the man had a 100 percent rating positive, and I dont really know what I am doing lol. Thanks everyone for your answers.

Freezing at initial android set up?

I just got my brand new OP3, opened it and turned it on to start setting it up, it freezes inside the android set up and then restarts itself after a few seconds of being frozen.
Any solutions? I really don't want to return it, I find it a bit stupid it doesn't even work out of the box

Might be a dud. They happen. RMA it.

I don't own this phone, but this happened to me with a Nexus, I turned it off, was able to get into recovery mode with button combinations, then I factory reset, cleared cache, and rebooted, it was fine.
I hope you can give it a try

Tried doing the Factory reset thing, no luck. Talked to OP support and the guy told me to submit a ticket with my issues, and that a "level 2 technician" would help me.
So I got home and plugged it into my PC, turns out the phone doesn't freeze when plugged in via USB. But on the included charger, and without being plugged into anything, it freezes and reboots itself in a continuous loop.

Keep us informed I'd like to hear what the problem/solution is

Hello, i have the same issue, did u find the solution ?

I also had my Oneplus 3 in a bootloop and freezing while showing either the 1+ square or the rotating red dots.
After I tried to get it repaired by talking with support and had been using my old phone for a few days and reflashing the ROM and recovery many times. I got it working again (ish) now it only freezes ones a day.
Support is a pain, I'm waiting for a level 2 techician for almost a week now.
So I any of you know a solution or have a confirmation that it is a hardware failure, I think we all would like to hear about it.

A5 Random Freezes and Restarts

Hello guys,
I just bought a brand new A5 2017 from a carrier centre and it restarts on an almost hourly basis. It works for maybe 1 or 2 hours normal, and then restarts by itself. When it boots up, I get messages of random apps crashing and then it restarts again. Once it restarted within minutes of each boot. I don't know the reason for this.
I have tried hard reset, soft reset, even flashing an AP firmware from Germany (I'm from Bosnia and Herzegovina), but with no luck. The phone just restarts when it wants.
Also tried safe mode, the same problem persists.
Any advice?

Try stock recovery and do factory reset. Vol. up, home and power buton. Btw. i think they are selling sh.t to eastern Europe (im from Croatia). I had bootloop on second day with A5 (2017). CPU was hot as hell. Recovery did not work, only desplaying error. But after 4-5 reset it came to normal. I was sending error log to samsung, they never answerd.

I did the reset with the vol up, home and power button about 5 times, and I still run into restarts. I really like the phone and wouldn't turn it back unless I had to. Do you have any more advice? Thanks!

Yes. After a gazillion factory resets (soft and hard), I performed a repair (initialization, if that's what the Smart Switch calls it) of the phone through the Smart Switch. It booted up and all was well until it restarted again. Next thing that I did was: wipe everything via a hard reset, and then repair the phone through Smart Switch. This was about 2-3 hours ago. Did run into 2 crashes (Google Play Services and Chrome) but I think it was related to the syncing, but no restarts and I hope not in the future.

Im glad to hear that. That was a softweare problem.

Just to give you an update. Unfortunately, the phone restarted again today, so I returned it to the carrier. They said they will send it for testing, and that I will most likely get a new device. Seems that it actually wasn't a software problem; my guess is that EMMC has a fault.
