[Q] Unrooted Evo won't boot

My friend has a completely unrooted, stock Evo. I'm not sure about the hardware version, and I hope it doesn't matter.
They were texting and using navigation with the phone plugged into a car charger, when it turned itself off and now won't turn back on. After a battery pull, it'll boot to the splash screen, but then shuts off again. After that, it doesn't boot at all.
I've tried getting it into fastboot, but I'm not incredibly familiar with the Evo. So far, no luck.
I have a rooted Incredible, so I've tried all the little tricks I've used to fix my phone.
So, any ideas? Bad hardware, bad software? Get it replaced?

My last Evo (I'm on my third one) was unrooted & would do something similar. At first it would just reboot itself, but then the screen would freeze & flicker and I would have to pull the battery then try to boot it up. Sometimes it would take 10 or so tries, but after it would boot up it would eventually do the same thing. At first doing a factory reset would fix it but then that stopped working.
If it's similar to my issue then it will have to be replaced. If your friend has insurance then they'll replace it for free since it isn't user damage. Until they get a replacement, try booting into fastboot & selecting reboot from there instead of just powering it on. That worked for me a few times.

I had tried the fastboot reboot, but it wouldn't even get that far.
Turns out, the navigation and texting had drained the battery faster than the car charger could charge it. After a full charge overnight, it's booting up fine. So it was fortunately a very simple problem.
Thanks for the reply, though.

[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

A100 blackscreen
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 won't turn on after rebooting to recovery...

I was going to update to latest AOKP, I selected reboot to recovery, phone turned off and never turned back on. I can't get into recovery mode either this is very odd any ideas?
This is very strange because this should not cause a hard brick... when I selected reboot to recovery it seemed like it froze for a second, but though it was just in the middle of restarting, then it just shut off. Why would that cause this, only thing I can think is maybe my battery drained... I have it hooked up to a charger right now. But like I said I can't get the phone to do anything.

Same thing happened to me with Galaxy Note from AT&T, I've been looking in several forums about this, but since the phone is not even charging the battery or booting, I'm loosing hope.

S III sgh-i747 turned off and wont turn on URGENT

i apologize if this has been solved but i am on a very tight time frame as i need this phone for work and cant spend any longer searching. my phone randomly turned off by itself this morning and will not turn back on. it gets to the samsung splash screen and the screen just goes black and the phone wont do anything, its like the screen is stuck off, i have to take the battery out to make it turn do anything at all again. it was stock this morning, never been rooted or anything, i just rooted it about an hour ago and installed twrp and flashed jedi invasion 5 on it in hopes it would help. now it gets past the splash screen and to the initial setup screen but it only stays on it for about 3 seconds before the screen goes black again and i have to take the battery out for it to do anything again. im not an expert by any means but i have flashed note 2's and played with them a bit and know my way arround them for the most part. any help would be EXTREMELY appreciated.
almost forgot to mention, in download mode it says qualcomm secureboot: enable
not sure if that means anything but i didnt get any errors while flashing or anything
thanks everyone

I would make sure you have to correct drivers installed for the phone on your computer and ODIN back to stock. You can give that a try and see if it helps.

I'll check that out when I get home but I'm pretty sure everything is right, it was doing it before I even flashed anything so I think something else is the problem

Faulty battery or power button. You can try ODIN back to stock, not likely it will help.

It's not a battery or power button problem. Before I rooted it if I took the battery out and turned it on again it would turn on fine if I kept the screen from turning off. and the battery was staying charged, and if it wer a power button problem why would it work to turn the phone on but not again after its on?

My vote is a faulty power button. Has been known to happen on the S3. Could be power issues though. Bad battery could be the culprit. If flashing stock does not work see if you can get a battery to test out.

ok so i flashed stock and it fixed it temporarily. after i flashed it it was working great so i decided to root it and flash jedi. so i did this and it still worked great. (at this point i should mention that the sim card in the phone has been deactivated this whole time) so since its working i activate the simcard, restart the phone, and the problem started again. so i took the sim card right out and turned it back on and it works perfectly fine without the sim card in... what do you guys figure? should i try a new sim card? has anyone ever herd of this happening before?
EDIT: tried my other sim card in it and it doesn't work either, so it snot the simcard itself

Phone Turning off by itself.

So I have this weird issue with my HTC ONE M7 for a few days now. It would turn off by its own when I was using it but I'd just turn it on and it will work again. I thought it may have something to do with a bad app or the rom might be acting up. Anyway I ignored it since turning it on was a minor inconvenience and I needed my phone functional. Today whilst using GPS, the phone suddenly went dead on me. Every time I boot it up, it passes the initial HTC screen but then doesn't boot into android. The screen goes black and the phone turns off by itself. I went it recovery, wiped dalvik and cache thinking it was an app causing a boot issue but that didn't help. The problem continued. I already had a backup so I went ahead and tried restoring it. It worked the first time. But the phone still won't boot. It would turn off automatically. Then I tried reflashing it with the backup. This time the phone would just turn off as soon as the restore process started. I finally got tired of it and decided to reflash with a new rom. The flash went fine. But lo and behold the same issue again. Boot animation and then black screen with the phone completely turned off.
I thought it might be the battery so I plugged it in to my laptop USB. It booted but when i was setting up android, it would just shut down again. Then I connected it to the wall socket thinking the phone will get more juice. This time around I was able to set it up. With the phone connected to the wall socket all was working splendidly. Please note that during all this time the phone was at 100% and there were no drastic falls in the battery levels.
As soon as I disconnect the phone from power, any power intensive operation shuts it down. I have been in recovery mode for 2 hours now and the battery hasn't even dropped by 3%.
So the question is, What the hell is going on? Is it the battery, is it phone's hardware or is it a software issue? Any help would be greatly appreciated. Cuz if it's something that can't be fixed, I have to start thinking about getting a new phone then. THANKS so much for bearing with me! Cheers!!

if you are s-off i would suggest doing an RUU and starting fresh. Its hard to pin point a problem without having the device handy and trying some things. The RUU will let us know if its a software problem or if its going to be hardware related.

Hey thank you so much for replying. I am s-off. But would going back to stock re S-On my phone? And how do I do RUU? Thanks again.

Do not s-on! Just run the ruu eye dottat made

Installed RUU. The problem is still there. The phone can stay on for hours in recovery without a charger but as soon i want too boot into android it shuts down. It only boots up if it's connected to a charger and that too a wall socket not a usb hub cuz it goes some way into the boot process and shuts down half way. I am pulling my hair out here. Dunno if it's the battery or the mother board.

If ruu still has issues. It is motherboard or battery. From the symptoms, it sounds like battery as the phone needs to have some juice to fully boot the phone before being able to run off the charger.
