[Q] Device stuck on ACER logo when booting - Acer Iconia A500

I know there have been many others with this problem and I've tried the most common solution: running recovery mode with an external SD. I've tried many different update files however it always get stuck on the stock recovery screen. The android is lying down with a red triangle and an exclamation mark - some files will show a loading bar under it while others do not. I have tried reset the tablet both by doing volume + power + lock screen sliding and manually resetting it via the button beforehand.
Any ideas?
Thanks

these instructions worked for me

Can't boot device

Hi, I've tried to flash device. But After rebooting I see always boot screen. If I press hone and power I see exclamation sign in white triangle. I appreciate if someone can you help?
I have Magic unlocked from Amazon. There was installed 1.5 platform. Also it has B class boot.
what happens if you dont press home and power.. will it normally boot up???
also you get the triangle because you have not yet installed any recovery image so that you can flash your device with any roms....

is it dead?

hello guys..i'm a newbie in android, and, i have a big problem now. i tried to install another rom instead of the stock one (spanish), and now my device doesn't start at all. i tried many ways, and each time i was able to go to fastboot menu or recovery menu. now, after i've done some steps from this tutorial: http://forum.xda-developers.com/showthread.php?t=491350&highlight=model+incorrect , my device keep restarting by himself. I cannot reach even recovery menu or fastboot menu. It starts the logo screen for 4-5 seconds, and after that is restarting and again the logo, even if i'm trying to press home+power or camera+power. what can i do???
My problem is like in this movie
if i press action button + power, nothing happends on the screen, but the blue led in the right top corners stays powered on. Do you know why?
If you cannot get in to recovery (home + power) or the SPL (power + camera) then you're doomed.
not even with jtag or something, cannot be done?
Unless you physically replace the motherboard (which doesn't look too hard) then no you can't. As of yet there's no Jtag method.

[SOLVED] [Q] Huawei U8180 First time Modder Problem

[SOLVED]
I rooted this, installed clockworkmod, then went and got an cm7 dated april something 2012 u8160 rom from psyke83 website.
installed it through clockworkmod install from sd card option with success (also clicked option to backup everything).
yet when phone reboots it hangs on the blue arrow in a circle spinning around, sometimes reboots n repeats but it never goes past that.
I have tried going into recovery mode holding down volume buttons and power
and I get 1 of 2 errors:
with sd card in:
firmware update
step 1/2
unpacking
update failed
with sd card out:
purple screen.
I am a first time android modder, can someone please, please tell me how to fix this. I can access the sd card with a reader if need be to put whatever files on it that I should.
Thank you.
Start the phone by pressing volume up + power OR volume down + power. You should be able to boot to recovery with one of those combinations (other one boots to fastboot most probably). After that do the wipe data/cache and try to reboot once again.
What was wrong in the beginning was that you did not wipe data/cache. That made the CM use old OS's data files which obviously won't work.
The unpacking thing was caused by pressing volume up + volume down + power. That causes the phone to go to upgrade mode if there is an update package found.
Nope. still goes to the blue arrow circling then freezes then reboots....

You are right about me not wiping the data/cache though...
But in your phone forum, are there tutorials on how to boot to recovery? Do you have any other hard keys on the phone?
there is one other button but that didn't work either.
I cannot find a forum for Huawei model u8180 (

Hmm, would this work?
yay!!
it was volume up + power + cancel button (? maybe home button? not sure on what this button is but its the biggest).
wiped all data n cache n then it booted properly.
So the problem is solved? If you can, mark first post title with [SOLVED].

[Q] Please help,phone works normally, but, getting Stuck on fastboot and recovery

Dear experts,
Phone model: Karbonn A9+
Rom: Custom Rom Hyperion Skyfall
When I hold the power button, the phone turns on and off, No problems with that.
However, when I press volume Up+Power, I get a green screen saying FASTBOOT at the top left corner and that’s it. Nothing happens from that point.
when I press volume Up+Power, I get a green screen and holding the buttons past that I get a red screen saying RECOVERY at the top left corner and that’s it. Nothing happens from that point.
However, when I press volume down+Power, I get a black screen saying ENTRY QPST DOWNLOAD at the top and that’s it. Nothing happens from that point.
I have to remove the battery to turn my phone off.
Moreover, I tried a factory reset erasing internal and external storage, after erasing when the phone is rebooted and gets stuck in the start-up screen. I removed the battery and powered on the mobile ,no problem at all the phone turns on but not resettted.
What I did?
Tried to install latest CWM through recovery, updated it but I pressed something instead of restart your device.
What should I do to make everything work again? I am a noob in Android, please be extra patient and illustrative
Many thanks in advance
same issue

I am facing the same issue...today i flashed "ClockWorkMod_Recovery_V6_-_Karbonn_A15.zip" . It was flashed successfully. But after that whenever I try to enter recovery mode using Power+ Volume up keys, it shows red screen... thats it....i do not see typical recovery screen menu. However the screen turns full white. Only option is to take out the battery and restart the phone.
PLEASE PLEASE PLEASE HELP

I think I bricked my ZTE Blade C2 v809

Please help me. I am in a sort of panic right now.
I have a ZTE Blade C2 v809, sold here in Portugal as Meo Smart A12. It was rooted and working fine. I was however getting some error 24's trying to install apps. I thought this might have had to do with using Titanium Backup to remove TouchPal (I did make a backup first), so I decided to restore TouchPal. There were however some errors in the restore and it was stuck there, so I decided to reboot the phone.
Chaos. Now it wont boot. If I press the button normally, the phone boots, I see the android logo, the screen goes black (Not shutdown black, a sort of light black background) and nothing happens. If I try to boot into Recovery mode by holding the power button and the volume down key, I just get the android logo stuck there, nothing happens. If I hold the power button and the volume up key, I get the picture of that laying down android with the message error.
Any more info I must provide please tell me, I am desperate for a solution, If I lose this phone I wont be able to get another one.
Okay I fixed it. Turns out the recovery menu DID work if I waited for a long time and tapped the screen. Used the update.zip available from the site, and it works like a charm
Yay, I bricked my phone, too.
I did something similar, changed recovery-from-boot.p name to recovery-from-boot.p-bak and install-recovery.sh to install-recovery.sh-bak
Now the phone doesn't boot properly, in fact it's stuck in a boot loop:
>starts
>shows white ZTE logo on screen
>restarts
Tried connecting the phone via USB cable and used fastboot devices & adb devices commands, no devices found.
Also tried pressing "power + vol down" and "power + vol up", nothing. I can't enter recovery mode or bootloader.
Apparently the remaining way to get in it's trough the SD slot, or maybe there's another way.
I kindly ask for help, couldn't be possible that I ruined this cell phone so fast.
Ideas, somebody?
