Hi,
My sister has a acer a100 tablet for some time now, and suddenly it won't boot, it's just stuck on the acer logo. The device is not rooted.
I've tried just about everything I could find on the internets. When I go into stock recovery, an android with a red triangle appears together with some yellow text mostly saying it couldn't mount anything, after a while I get the recovery option, but am unable to select anything, I can toggle between them, but pressing the power button doesn't do anything.
I've also tried some fastboot tricks I found, but no luck.
I don't know if she was installing some firmware update and then shut it off (she says no), so I don't really know which android version she has.
I hope someone can help me figure this.
thanks in advance!

Take a look at the brick thread, sounds like a perfect example of the brick bug.

Hi! First of all, I tried searching the forum, but I failed find any specific help on this. I hope someone can point me in the right direction, or knows how to solve this.
I tried to install manually an OTA uptade on my desire, and I think I may have screwed up something.
When I power up the phone, it's stuck in booting: boots, HTC logo comes up, vibrates, then the whole cycle starts.
I was able to get to the screen, with the skating droids, but when I tried to choose recovery, an image of a phone comes up with nothing but a red triangle.
Does anyone know how to fix this? Any help would be appreciated.
Stock android 2.2, rooted with unrevooked.
to leave the triangle-screen:
-press Volume up ("+") and the power-button.
-select "Reboot system now"
..and you're done!
tried that, but it still ends in an endless boot loop. Also tried factory reset.
Nevermind, looks like there was some kind of hiccup the first time. I started the OTA update manually (after leaving the triangle screen with the vol. up + power combo) and after some rebooting it wokrs now. And it's updated too. Thanks anyway!

Google: red triangle of death.
Good luck.
Hi, guys!
This is nearly my first time here reporting a problem, but I'm really stuck and I'm pretty sure that you'll be able to help me.
I have a GSM Galaxy Nexus i9250 which was on Stock Rom without Root (even though it was rooted and back to normal afterwards). Last night I left my phone plugged to the wall, charging. Let me tell you that the phone was on, too. The following day (I mean, this morning) when I went to pick up the cellphone, I found that it was in an infinite bootloop. Google logo, X logo, Google logo, X logo... And so on.
The first thing I thought about, was changing the battery, considering the fact that I had been using the extended one. Despite from that, It didn't work.
After that, my second idea was to flash the factory image again, but the issue wasn't solved. At first, I was able to actually see my phone working on (I was ver close to choose the language!) but the reboot came up again.
Last but not least, my last chance was to try to solve the problem via Recovery Mode. When I tried to go down that road, a tiny Android appeared on my screen, with its chest opened and a red triangle over him.
I ran out of ideas, but surely you'll have come great tips or another magic trick regarding this problem.
Thanks a lot in advance!

Hey, thanks for your help!
Unfortunately, that didn't do the trick... =/
Whenever I try to wipe cache, the process begins and the phone resets again... And again... And again.
Could it be a HW issue?
Thanks!
Hello, I have the same problem, which appeared about week ago. I was going sleep when my phone froze. I plugged charger then (I was too tired to wait) and next morning my phone was in infinite loop. After reflashing stock firmware all was good but only for a while... When I replaced all the content I had, bootloops appeared sometimes ending infinite and sometimes just only 1 or 2. By now I don't know what to do. Firstly I thought that it was maybe because of root access for some crappy app, but even without root it still happens. I even tried not to restore backup from Play Store, but with no luck.
Is there any way to see some log and discover what is causing trouble?
Any help is really needed!
Sideload .zip if youre unlocked or do a factory reset

Hi
If you turn on usb debugging in the developer options, you can then do adb logcat while it's bootlooping.
That will at least show you what's failing. Also adb shell dmesg gives you the kernel messages.
Logcat is pretty easy to follow once you get over the information overload you will see it looping after a short while
Edit: obviously if it's bootlooping you can't get into developer option. You can access adb via recovery. You should be able to "adb shell cat /proc/last_kmesg" . Doing that after failed boot attempt will give you the kernel output from the last boot. Theres ways to enable debugging for booting from recovery I'll double check it when I get in
Hope that helps a little

Hi All,
Really hoping someone can suggest a possible solution for this one, only had the phone a few months!
So, Chinese released M9. Unlocked. Stock recovery, not rooted. Gapps installled.
Everything perfect, then today I got the 5.1 update.
Seemed like a slightly iffy install process...looked a little like it failed a couple of times and tried again.
Finally finished, the phone shows the white screen with the one logo, takes a while, opens on the desktop and turns off, back to the white screen with the logo.
I have been able to boot into safe mode, which is stable
I have been able to get to download mode and bootloader. Neither of these offer a cache wipe or a factory reset.
I have not been able to get into recovery mode, it shows a phone with a red triangle and an exclamation point.
So for my (largely uneducated) part I have two theories for the cause:
1) Gapps is somehow proving a problem, either faulting the install or causing a fatal error on startup
2) Since the update was notified and downloaded while on a VPN via Hong Kong, I wonder if I accidentally ended up with the HK version in which case I suspect there may be hardware differences (at least the radio). This seems unlikely, I would hope there were enough checks in place to prevent this happening.
No solid idea where to go from here. I have not yet tried ADB access, but even if I can connect, what will I do? Flash a new ROM? I'd rather not. And surely I'd need to root in order to do that....
At a loss, any potential solutions welcomed whole heartedly!
Thanks...
Booting into safe mode, but not booting otherwise, indicates a problem with some app or rom setting.
You're probably going to need to do a factory reset, but that's odd that it doesn't show up in bootloader or download mode. Have you tried the options in stock recovery (which is that screen with the red triangle)? Use the volume keys to change options.
Hi iElvis - the screen with the red triangle - there's nothing other than the red triangle, no options, no text and nothing happens if I press any of the physical buttons.
Trying a factory reset from safe mode - I'll let you know what happens!

Hmm. It would seem the Chinese models are set up differently, which would not surprise me at all.
Just today, out of nowhere my phone restarted itself and got stuck in a bootloop. I tried to boot into recovery mode, but that wouldn't work either. Every now and then when I tried to go to recovery mode it would say "no command." Now the phone wont turn on at all. I am not rooted, so just running stock Nougat. Does anyone have any advice or links to tutorials that I can use?
Thanks in advance.

Sadly you're facing the bootloop of death which renders the device completely useless, no tutorial is gonna work for you to be able to fix it. You should send it to Google or LG if it's still under warranty to get a replacement.
Unfortunately sounds like an hardware issue, no tutorial can fix it.

Did you press and hold the "Power" and "Volume Up" Button after that "no command"? Then just release the Volume Up Button to access Stock Recovery.
I haven't. I'll give that a try assuming I can even get it to that point again haha.
I have the same problem, and now its completely die
So i tried rooting my samsung. with this option
and now its stuck on the twrp logo and it doesnt even turn off it just loads the logo again and again please i need help quick.
Can't enter anything. And the phone doesn't show up in odin. I can only restart the phone
Managed to open it in recovery? somehow its showing up on abd
Seeing how you really are rather new an all, Plus the fact no body else has mentioned anything, I have to ask....
